Re: Draft Stormwater Discharge Master General Permit Renewal NJ0141852 (Category Code R9)
For Tier A Municipal Separate Storm Sewer Systems (aka the Tier A MS4 NJPDES Permit)
The
New Jersey Department of Environmental Protection (the Department) is proposing to renew the Tier A MS4
NJPDES Master General Permit (NJ0141852). The conditions of this permit were last renewed in 2018 and
continue in force pending completion of the renewal process (see N.J.A.C. 7:14A-2-8). A copy of the draft Tier A
MS4 NJPDES Master General Permit is attached to this cover letter.
Enclosed is the public notice for the draft renewal of the Tier A MS4 NJPDES Master General Permit. The permit
renewal will also be public noticed in the Atlantic City Press, Star-Ledger, The Times, and on August 3 in the DEP
Bulletin. Included in the public notice are instructions and requirements for the submittal of comments by a
specified date, information about a public hearing, and other procedures for reaching a final permit decision in
accordance with N.J.A.C. 7:14A-15, 16, and 17.
The
draft Tier A MS4 NJPDES Master General Permit and supporting documents will be posted at
www.nj.gov/dep/dwq/tier_a.htm. I trust that these documents will be useful in understanding the draft permit as
well as for preparing comments on the draft permit. Specific questions about the renewal process may be addressed
to stormwatermanager@dep.nj.gov.

PUBLIC NOTICE
Notice is hereby given that the New Jersey Department of Environmental Protection (Department) proposes to
renew the Tier A New Jersey Pollutant Discharge Elimination System (NJPDES) Master General Permit
(NJ0141852). Renewal of this permit is in accordance with N.J.A.C. 7:14A, and by authority of the Water
Pollution Control Act at N.J.S.A. 58:10A-1 et seq.
This permit renewal serves to authorize discharges from Municipal Separate Storm Sewer Systems (MS4) from
New Jersey Tier A Municipalities. Stormwater runoff is commonly transported through MS4s before discharging
into local waterbodies. A full copy of the proposed Master General Permit renewal for Tier A is available at
www.nj.gov/dep/dwq/tier_a.htm.
The regulation of stormwater runoff through the Tier A MS4 NJPDES permit is intended to provide water quality
benefits and prevent increased flooding and erosion. The permit is a regulatory mechanism which addresses
stormwater quality and quantity issues related to public works operations, new development, redevelopment, and
existing developed areas by requiring Tier A Municipalities to implement stormwater programs. New Jersey’s
MS4 permit program is prescriptive in nature in that it clearly defines specific permit requirements that incorporate
the Statewide Basic Requirements (SBRs) and other regulatory requirements applicable to Tier A Municipalities.
This includes requirements that pertain to Public Involvement and Participation, Local Public Education and
Outreach, Post Construction Stormwater Management in New Development and Redevelopment, Pollution
Prevention/Good Housekeeping for Municipal Operators, MS4 Mapping, Stream Scouring Detection and Control,
Illicit Discharge Detection and Elimination, and development of a Watershed Improvement Plan.
The Department is establishing a 45-day public comment period for this proposed permit renewal. Written
comments may be submitted via e-mail to stormwatermanag[email protected]. Written comments may also be
submitted to Gabriel Mahon, Chief, or Attention: Comments on Public Notice NJ0141852, at Mail Code 501-
02A, Bureau of NJPDES Stormwater Permitting and Water Quality Management, P.O. Box 420, Trenton, NJ
08625-0420. The public comment period closes 45 calendar days after the last publication in the newspaper or
September 20, 2022 whichever is later. All persons who believe that any conditions of this draft document are
inappropriate must raise all reasonable arguments and factual grounds supporting their position, including all
supporting materials, during the public comment period. All materials supporting a comment shall be included in
full and may not be incorporated by reference. The Department requests that comments submitted on this permit
renewal be numbered and identify the permit requirement subject to the comment in order to adequately respond
to all comments.
The Department will hold a virtual non-adversarial public hearing via Microsoft Teams to solicit public comment
on the Tier A draft permit on September 20, 2022 from 9 A.M. to 12 P.M. The public hearing will be re-opened
from 1:00 P.M. to 4:00 P.M. to accommodate additional individuals if the attendance limitation for the 9:00 A.M.
to 12:00 P.M. Microsoft Teams session is exceeded. The public hearing will close at 12:00 P.M. for the first
session and 4:00 P.M. if a second session is held, or at end of testimony, whichever comes first.
The hearing shall be held before a Hearing Officer designated by the Department. Interested persons will have
the opportunity to electronically present and submit information on the proposed action.
This draft NJPDES permit renewal has been prepared, based on the administrative record which is on file at the
offices of the Department, located at 401 East State Street, Trenton, New Jersey. It is available for inspection, by
appointment, Monday through Friday, between 8:30 A.M. and 4:00 P.M. Appointments for inspection may be
requested through the Open Public Records Act office. Details are available online at www.nj.gov/dep/opra, or
by calling (609) 341-3121.
The Department will respond to all significant and timely comments upon issuance of the final documents. All
individuals and entities that submit written comments will receive notice of the Department’s permit decisions.

This fact sheet sets forth the principal facts and the significant factual, legal, and policy considerations
examined during preparation of the draft permit. This action has been prepared in accordance with the
New Jersey Water Pollution Control Act and its implementing regulations at N.J.A.C. 7:14A-1 et seq. -
The New Jersey Pollutant Discharge Elimination System (NJPDES).
PERMIT ACTION: Tier A Municipal Stormwater New Jersey Pollutant Discharge Elimination
System Master General Permit Renewal for Municipal Separate Storm Sewer
Systems (the Tier A MS4 NJPDES Permit) A Comprehensive General
Permit under 40 CFR 122.28
Precipitation that reaches the ground is either lost by evapotranspiration, infiltrates into the ground below
the root zone (becoming groundwater) or becomes stormwater runoff. Stormwater runoff flows from
rooftops, over paved areas and bare soil, and through sloped vegetated areas while picking up a variety of
sediments and pollutants on its way. The quantity and quality of stormwater runoff is affected by many
factors including the season, local meteorology, geography, topography, land cover, and the activities which
lie in the path of the flow. Impervious surfaces, such as rooftops and pavement, can increase the probability
of downstream erosion and flooding. The quality of the stormwater runoff depends on the associated
pollutants within the flow path of the stormwater. Although the amount of pollutants from a single site may
seem unimportant, the cumulative effect of pollutants accumulating in stormwater runoff from multiple
sites can negatively surface water quality.
Stormwater runoff is commonly transported through Municipal Separate Storm Sewer Systems (“MS4’s”)
before discharging into local waterbodies. In an effort to prevent harmful pollutants from being washed into
and/or transported from an MS4 into local waterbodies, Federal stormwater regulations require MS4
operators to obtain a National Pollutant Discharge Elimination System (NPDES) permit and implement a
stormwater management program. New Jersey Pollutant Discharge Elimination System (NJPDES”) rules
also require MS4 operators to obtain a NJPDES permit and develop a stormwater program. N.J.A.C. 7:14A-
24 and 25 et seq. This permit renewal is a Comprehensive General Permit (under 40 CFR 122.28), which
serves to authorize MS4 stormwater discharges from New Jersey Tier A municipalities and requires those
respective municipalities to develop a stormwater program.
The regulation of stormwater runoff through this permit renewal is intended to continue to provide
substantial water quality benefits, as well as provide enhanced water quality and quantity benefits through
changes the Department deems necessary. These changes are based on current information applicable to
stormwater related concerns, which includes, but is not limited to, surface water quality impairments as per
the final 2016 and draft 2018/2020 Integrated Reports, adopted/approved Total Maximum Daily Loads
(TMDLs), the presence of Harmful Algal Blooms (HABs), the Surface Water Quality Standard water
quality classification upgrades to N.J.A.C. 7:9B that occurred in May 19, 2003, November 3, 2003, August
2, 2004, June 20, 2005, June 16, 2008, and April 6, 2020, as well as the serious stormwater flooding that
has resulted from recent storm events, including Hurricane Ida.
Information gathered from across the country has shown that stormwater runoff has a high potential to
contain various pollutants. Pollutants found in stormwater runoff may include, but are not limited to;
FACT SHEET
1. Introduction
2
benzene and other volatile organic compounds (“VOCs”) from gasoline, motor oils and other vehicle fluids
(from spills, leaks and accidents); asbestos and various metals from brake pad and other vehicle component
wear and tear, rubber and other material from the breakdown of tires, excess phosphorous and nitrogen
from fertilizers, various oxygen demanding parameters from coffee, juice, soda, etc. being poured/spilled
by pedestrians, excess nutrients and pathogens from various wildlife such as birds, raccoons, etc. and illicit
connections, salt and related additives and/or impurities from deicing procedures, fertilizers and pesticides
from landscaping/lawn areas, and soaps and detergents from vehicle washing, or from power washing of
decks/sidewalks, and buildings. All of these pollutants have an effect on the surface and ground water
quality, including the numerous waters that are used for drinking water across the state. Some of these
pollutants are toxic or carcinogenic in very small amounts, such as benzene and asbestos, while the
pathogens from animal droppings and HAB’s can cause serious health effects for those that come in contact
with them. (see also How common road salts and organic additives alter freshwater food webs: in search
of safer alternatives - Schuler - 2017 - Journal of Applied Ecology - Wiley Online Library)
Water quality concerns were a main driving force behind the development of previous Tier A MS4 permit
requirements. A number of permit conditions have been added or enhanced in this renewal based on a more
recent, comprehensive statewide review of current water quality information and stormwater related
concerns. After completing compliance audits of 58 towns (almost 13% of the current 456 Tier A
municipalities) from 2015 through 2020, and online compliance evaluations of all of the Tier A
municipalities during the COVID pandemic, the Department found many instances of non-compliance with
permit conditions that can directly affect water quality. For example, for the 37 audits that were conducted
since the 2018 permit renewal became effective, many municipalities were not aware that the permit
required them to prioritize maintenance and repairs in the portions of their storm sewer system that
discharged into waterbodies assigned TMDLs. Many Stormwater Pollution Prevention Plans (“SPPP’s”)
did not contain the required basic identification of TMDLs that affected the municipalities’ receiving
waterbodies, even though that information has been made readily available to the municipalities via the
Department’s TMDL Look-up tool (https://www.nj.gov/dep/dwq/msrp-tmdl-rh.htm
).
The proposed enhanced permit requirements that are related to inspection and proper operation and
maintenance of all permittee-owned or operated storm sewer infrastructure, are aimed to improve the
control of pollutants, such as nutrients, pathogens, solid and floatable materials, and other harmful
pollutants that can harm the quality of our surface and ground waters of the state. In addition, proper
operation and maintenance is also necessary to ensure that stormwater infrastructure is able to convey
stormwater to the designated discharge location and reduce localized flooding. The enhancements to the
conditions in the 2018 MS4 Tier A permit are generally based on the objective of furthering the
improvement of water quality and quantity impacts from stormwater runoff throughout the state and are
identified and discussed in Section 7 of this Fact Sheet, entitled, “Basis and Background of Tier A Permit
Requirements.The Department maintains proper implementation of the conditions of this renewal permit
will provide a continued, iterative process towards improving stormwater quality.
The Department also maintains that no conditions contained in this renewal permit constitute an unfunded
mandate under Article VIII, Section II, paragraph 5 of the New Jersey Constitution, or N.J.S.A. 52-13H.
This determination is due to the fact that the requirements contained in this permit renewal are based on
improving water quality impairments and TMDLs as required by the Federal Clean Water Act (Act), and
because the MS4 permittees now have the ability to form stormwater utilities like many other jurisdictions
across the country since the 'Clean Stormwater and Flood Reduction Act' was signed into law in March of
2019. Specifically, where the legislative branch has provided an adequate funding mechanism that can
cover expenses associated to a mandate associated with a statute, rule, or regulation, the mandate cannot be
considered an unfunded mandate. (In the Matter of a Complaint Filed by Ocean Township (Monmouth
County) and Frankford Township. at 5-6 (Aug. 2 2002)).
3
The 'Clean Stormwater and Flood Reduction Act' became effective after the issuance of the 2018 permit,
and allows a municipality alone, or together with other municipalities, or as a part of a regional entity, to
form a stormwater utility to finance the improvement of the State's stormwater infrastructure, better control
water pollution and flooding, restore and enhance the quality of the State's waters, and protect the public
health, safety, and welfare and the environment by correcting inadequate stormwater infrastructure and
management. The stormwater utilities formed under this Act are required to charge fees based on a fair and
equitable proportional contribution of stormwater runoff from the properties in the utility’s jurisdiction in
order to fund their unique set of stormwater needs.
Specifically, as per the Act:
The Legislature finds and declares that:
1. The State of New Jersey faces an extensive set of problems due to inadequate stormwater infrastructure
and management, and these problems directly affect the health, safety, economic well-being, and
quality of life of New Jersey residents. When storms occur, rainwater runs off of impervious surfaces
such as roads, roofs, and parking lots, and into stormwater management systems and waterways. This
stormwater carries with it oil, pesticides, other chemicals, sediments, and bacteria that may contaminate
State waters, potentially making them unsafe for drinking, fishing, and recreational purposes. It is
estimated that up to 60 percent of the State's existing water pollution is attributable to stormwater and
nonpoint sources of pollution. Additionally, if a stormwater management system is not in place or is
not able to adequately absorb, capture, or convey stormwater, then runoff in large volume and force
may cause flooding and damage to homes, businesses, and property. A projected increase in sea level
rise and more frequent and severe storms are expected to only increase flooding.
2. New Jersey, in particular, is prone to pollution and flooding problems, with over 10 percent of its land
area covered with impervious surfaces. These problems are particularly acute in the 21 urban New
Jersey municipalities that have combined sewer systems, which routinely overflow and discharge
untreated wastewater and stormwater into the State's waters, contributing to water pollution and
impairing the use and enjoyment of those waters.
3. Stormwater infrastructure in New Jersey currently lacks a dedicated source of funding and,
consequently, receives few upgrades and little maintenance once built. In some instances, stormwater
infrastructure goes unmonitored and unattended until it breaks down; in other instances, it is simply
inadequate to manage stormwater.
4. Establishment of local stormwater utilities presents an effective management strategy to address
stormwater issues. Currently, there are more than 1,500 stormwater utilities operating in 40 states across
the country and the District of Columbia. Stormwater utilities are often authorized to assess fair and
equitable fees to fund the development, improvement, and management of stormwater infrastructure.
The Legislature therefore determined that it is in the public interest to authorize the establishment of local
stormwater utilities, and to allow those utilities to assess fees that are based on a fair and equitable
approximation of the proportionate contribution of stormwater runoff from any real property, in order to
finance the improvement of the State's stormwater infrastructure, better control water pollution and
flooding, restore and enhance the quality of the State's waters, and protect the public health, safety, and
welfare and the environment.
The Act allows the utilities to use the monies collected from these fees and other charges for various
activities related to stormwater management, as follows:
1. Initial establishment of a stormwater utility pursuant to P.L2019, c.42 and ongoing related
administrative expenses;
2. Capital expenditures, including planning, design, engineering, acquisition, construction, and
4
improvement of a stormwater management system;
3. Operation and maintenance expenditures of a stormwater management system;
4. Development and implementation of an asset management program for a stormwater management
system;
5. Development and implementation of a stormwater management plan and stormwater control ordinances
pursuant to section 1 of P.L.1981, c.32 (C.40:55D-93);
6. Any action required pursuant to any New Jersey Pollutant Discharge Elimination System permit;
7. Development and implementation of any long-term control plan to mitigate combined sewer overflows
pursuant to State or Federal law, rule, regulation, permit, or consent decree;
8. Monitoring, inspection, and enforcement activities to carry out the purposes of P.L2019, c.42;
9. Public education and outreach related to stormwater management; and
10. Any other purpose related to stormwater management as may be authorized by the department, the
Division of Local Government Services in the Department of Community Affairs, or the Local Finance
Board pursuant to rules, regulations, or permits.
More detailed information regarding the Act as well as the guidance information that the Act required the
Department to create is available on the Department’s website at

Federal MS4 stormwater regulations were issued in two phases:
Phase I, issued in 1990, requires medium and large cities or certain counties with populations of 100,000
or more to obtain NPDES permit coverage for their stormwater discharges;
Phase II, issued in 1999, requires regulation of small MS4s (which are smaller jurisdictions) to obtain
NPDES permit coverage for their stormwater discharges; and
The Phase II stormwater rule was revised by the United States Environmental Protection Agency (EPA
or USEPA) in 2016 as a result of litigation (see
www.epa.gov/npdes/npdes-st
ormwater-final-ms4-
general-permit-remand-rule). The 2016 rule change “does not change the stringency of the underlying
requirements in the statute or Phase II regulations to which small MS4 permittees are subject, nor does
it establish new substantive requirements for MS4 permittees” (81 F.R. 89322). The rule revision
primarily addresses procedural issues and “establishes two alternative approaches a permitting
authority can use to issue NPDES general permits for small MS4s and meet the requirements of the
court remand. The first option is to establish all necessary permit terms and conditions to require the
MS4 operator to reduce the discharge of pollutants from its MS4 to the MEP [maximum extent
practicable], to protect water quality, and to satisfy the appropriate water quality requirements of the
Clean Water Act (MS4 permit standard) upfront in one comprehensive permit. The second option
allows the permitting authority to establish the necessary permit terms and conditions in two steps: A
2. Federal Stormwater Regulations

first step to issue a base general permit that contains terms and conditions applicable to all small MS4s
covered by the permit and a second step to establish necessary permit terms and conditions for
individual MS4s that are not in the base general permit. Public notice and comment and opportunity to
request a hearing would be necessary for both steps of this two-step general permit. This final rule does
not establish any new substantive requirements for small MS4 permits.” [language added]. 81 Fed. Reg.
89320 (December 9, 2016). The Department is renewing this permit under the first option by issuing a
Comprehensive General Permit under 40 CFR. 122.28.
Small MS4s that are located within the boundaries of a Census Bureau defined "urbanized area" are
regulated under the EPA Phase II Stormwater Rule. Small MS4s also include those MS4s that are not
covered under the Phase I Regulation. Small MS4 means all municipal separate storm sewers (other than
“large” or “medium” municipal separate storm sewer systems as defined in N.J.A.C. 7:14A-1.2) that are:
Owned or operated by municipalities described under N.J.A.C. 7:14A-25.2(a)1;
Owned or operated by county, State, interstate, or Federal agencies, and located at public complexes as
described under N.J.A.C. 7:14A-25.2(a)2;
Owned or operated by county, State, interstate, or Federal agencies, and located at highways and other
thoroughfares as described under N.J.A.C. 7:14A-25.2(a)3; or
Owned or operated by county, State, interstate, Federal, or other agencies, and receive special
designation under N.J.A.C. 7:14A-25.2(a)4.
No urban areas in New Jersey currently qualify as a large or medium MS4s. Rather there are only small
MS4s. The Federal Phase I rules did identify Paterson, Perth Amboy and Jersey City as medium MS4’s,
and Newark as a large MS4. However, these municipalities are served primarily by combined sewers which
are regulated under NJPDES permits for combined sewer systems rather than as medium or large MS4’s.
The populations in the areas that are served by separate storm sewers within these municipalities are below
the threshold to trigger the medium or large MS4 permits. Therefore, all MS4s covered under this permit
are “small MS4s.”
The Federal regulations also require discharges to obtain NPDES permits for water quality reasons in
addition to the requirement based on population in an urbanized area that is discussed above. Stormwater
discharges that contribute to a water quality impairment or are a significant contributor of pollutants to the
receiving waters are not exempt from obtaining a NPDES permit. Specifically, 40 CFR 122.26 states that
“… discharges composed entirely of storm water shall not be required to obtain a NPDES permit except:
(v) A discharge which the Director, or in States with approved NPDES programs, either the Director
or the EPA Regional Administrator, determines to contribute to a violation of a water quality standard
or is a significant contributor of pollutants to waters of the United States. This designation may include
a discharge from any conveyance or system of conveyances used for collecting and conveying storm
water runoff or a system of discharges from municipal separate storm sewers, except for those
discharges from conveyances which do not require a permit under
paragraph (a)(2) of this section or
agricultural storm water runoff which is exempted from the definition of point source at § 122.2.
The Director may designate discharges from municipal separate storm sewers on a system-wide or
jurisdiction-wide basis. In making this determination the Director may consider the following factors:
8
(A) The location of the discharge with respect to waters of the United States as defined at
40 CFR
122.2.
(B) The size of the discharge;
(C) The quantity and nature of the pollutants discharged to waters of the United States; and
(D) Other relevant factors.
The Federal Phase II Rule at 40 CFR 122.34 requires that operators of small MS4s develop, implement,
and enforce a program that includes six minimum control measures to minimize the amount of pollutants
discharged into receiving waterbodies from small MS4s. The Federal Six Minimum Control Measures are
as follows:
1. P
ublic Education and Outreach: Distribution of educational materials and performance of outreach to
inform citizens about the impacts polluted stormwater runoff discharges can have on water quality;
2. P
ublic Involvement/Participation: Providing opportunities for citizens to participate in program
development and implementation;
3. I
llicit Discharge Detection and Elimination: Development and implementation of a program to detect
and eliminate illicit discharges to the MS4;
4. C
onstruction Site Storm Water Runoff Control: Development, implementation and enforcement of an
erosion and sediment control program for construction activities that disturb one or more acres of land;
5. Po
st-Construction Storm Water Management in New Development and Redevelopment: Development,
implementation, and enforcement of a program to address discharges of post-construction storm water
runoff from new development and redevelopment areas; and
6. P
ollution Prevention/Good Housekeeping for Municipal Operations: Development and implementation
of a program with the goal of preventing or reducing pollutant runoff from municipal operations.
A. Regulatory Background
Stormwater discharged from an MS4 is regulated through both Federal and state rules. In response to
EPA’s 1999 Phase II stormwater rules, the Department promulgated:
The Phase II NJPDES Stormwater rules, N.J.A.C. 7:14A-24 & 25
(https://www.state.nj.us/dep/dwq/714a.htm
) ad
ministered as the Additional Requirements For
Certain Stormwater Discharges and the Municipal Stormwater Regulation Program
(www.nj.gov/dep/dwq/msrp_home.htm), respectively.
The Stormwater Management rules, N.J.A.C. 7:8 administered as the Stormwater Management
Program (https://www.njstormwater.org/).
Formally defined at N.J.A.C. 7:14A-1.2, a “municipal separate storm sewer system,” aka MS4, is
generally a conveyance or system of conveyances that ultimately discharges to waters of the State and:
Is owned or operated by a town, township, city, borough, village, county, state, or other public
entity;
3. New Jersey Municipal Stormwater Program
9
Is designed or used to collect or convey stormwater;
Is not a combined sewer;
Is not part of a publicly owned treatment works (e.g., sewage treatment system); and
Includes curbs, gutters, ditches, manmade channels, storm drains, catch basins, municipal streets,
or roads with drainage systems.
To protect water quality, and to satisfy the appropriate water quality requirements of the Clean Water
Act, the MS4 State rules (N.J.A.C. 7:14A-25) require the Department to issue permits regulating each
small MS4. These MS4 permits specify the minimum control measures that must be implemented by
the permittee. These control measures serve to reduce the discharge of pollutants from the Tier A
municipality’s MS4, municipal maintenance yards and other ancillary operations, to the maximum
extent practicable pursuant to N.J.A.C. 7:14A-25.6(a)1 and 40 CFR 122.34(a) to protect water quality
and to satisfy the appropriate water quality requirements of the Clean Water Act. The benefit of this
approach was described in the NJPDES rule adoption notice published in the February 2, 2004 New
Jersey Register (See 36 N.J.R. 828-829).
New Jersey’s NJPDES MS4 permit program was developed under N.J.A.C. 7:14A-25 et seq., which
requires all New Jersey municipalities; state, county and interstate transportation entities; and certain
public complexes to apply for a NJPDES permit. N.J.A.C. 7:8 et seq. established the requirements for
stormwater management plans and stormwater control ordinances, design and performance standards
for stormwater management measures, and long-term operation and maintenance of stormwater
management measures. The following Master General Permits currently address stormwater discharges
from these MS4s in New Jersey:
Tier A Permit (NJ0141852);
Tier B Permit (NJ0141861);
Public Complex Permit (NJ0141879); and
Highway Agency Permit (NJ0141887).
To administer these Master General Permits, the Department issues each eligible entity a separate
General Permit Authorization to discharge under one of the above listed general permits. Because New
Jersey does not currently have any municipalities that operate medium or large MS4s, as explained
above, all municipalities operate “small MS4s.” The Tier A Municipal Stormwater Master General
NJPDES permit authorizes the discharge of stormwater from small MS4s for Tier A Municipalities in
New Jersey, which include eligible discharges from municipal maintenance yards and other ancillary
operations owned or operated by those Tier A municipalities. It should also be noted that stormwater
discharges from wood chipping and leaf composting activities are no longer authorized under this
general permit. Those discharges will now require authorization under the new Wood Waste Recycling
and Leaf Composting NJPDES Stormwater Master General Permit. Further discussion regarding this
change from the 2018 permit is included later in this fact sheet under Section 7.F.5., Municipal
Maintenance Yards and Ancillary Operations.
This MS4 NJPDES Master General Permit is a Comprehensive General Permit (under 40 CFR 122.28)
which identifies the requirements necessary to “reduce pollutants to the maximum extent practicable,
protect water quality and satisfy the appropriate water quality requirements of the Clean Water Act”
from stormwater discharges. Under the Department’s MS4 general permit program and consistent with
N.J.A.C. 7:14A-6.13, a general permit is the means by which the Department regulates a large number
of similar dischargers. To request authorization under the general permit, municipalities submit a
Request for Authorization (RFA) which represent a formal acceptance of the terms of the general
permit. See N.J.A.C. 7:14A-6.13(d). As provided by N.J.A.C. 7:14A-6.13(d)9 and 25.4(a)3, upon
10
reissuance of this general permit, existing authorizations shall be automatically renewed using the
information provided in the permittees’ most recently submitted RFA (see Part II.B.1 of the draft
permit) and the information collected by the Department in each permittee’s Annual Report and
Certification received electronically through the Department’s Regulatory Services Portal.
Alternately, a permittee may request their stormwater discharges be authorized under an individual
stormwater permit, as described in N.J.A.C. 7:14A-6.13(g). Any permittee pursuing authorization
under an individual stormwater permit shall submit an application (see
https://nj.gov/dep/dwq/forms_storm.htm
) under N.J.A.C. 7:14A-4 et seq. with reasons supporting the
request for the individual permit. Additionally, the application for the individual permit must contain
the information required under 40 CFR §122.33(b)(2). The Department will grant the request if the
reasons and information cited by the permittee are determined to be adequate to support the request.
B. Regulation of Stormwater from Existing Development
The pollutants discharged from small MS4s vary and may contain conventional and non-conventional
pollutants such as pathogens/bacteria, nutrients, total suspended solids, dissolved solids, petroleum
hydrocarbons, metals, volatiles, pesticides, PCBs, and solid and floatable material. The concentration
of pollutants as well as the volume of the stormwater discharged from each MS4 outfall is directly
linked to factors such as land use, development, percent of impervious surface, and human activities
that occur in the drainage area.
Under N.J.A.C. 7:14A-25.6 and as required under General Permit Authorizations issued under the
general permit, Tier A Municipalities are required to implement various control measures to reduce
pollutant loadings to watersheds from existing development. Specifically, and consistent with the
general permit requirements included under 40 CFR 122.28, each municipality must develop,
implement, and enforce a stormwater program. Pursuant to N.J.A.C. 7:14A-25.6(a)3, the Tier A
Municipality must document its stormwater program in a Stormwater Pollution Prevention Plan
(SPPP). The SPPP must describe the measures necessary for compliance with the permit, including the
Statewide Basic Requirements (as developed to implement the Federal six minimum control measures
at 40 CFR 122.34) and other permit conditions. Some examples of control measures that are required
to be described in the SPPP include documentation of permit required adoption and enforcement of a
pet waste disposal ordinance, prohibition on the feeding of unconfined wildlife on public property, and
catch basin cleaning. The Department has developed a free SPPP template at
https://nj.gov/dep/dwq/tier_a.htm
for municipalities to use to assist with this requirement.
C. Regulation of Stormwater from New Development and Redevelopment
Post-construction stormwater management in new development and redevelopment are components of
the minimum control measures at 40 CFR 122.34(b)(5). The regulatory standards to ensure that the
stormwater measures of such developments are both properly designed, constructed, and thereafter
maintained lie largely in the Stormwater Management rules (N.J.A.C. 7:8), which are incorporated as
part of the overall Federal municipal stormwater program consistent with 40 CFR 122.34(c).
The Stormwater Management rules at N.J.A.C. 7:8 set forth the required components of a Municipal
Stormwater Management Plan (MSWMP). As an integral part of a municipality’s master plan, the
MSWMP details the municipality’s strategy, measures, and process to manage post construction
stormwater runoff from new development and redevelopment to ensure compliance with N.J.A.C. 7:8.
The MSWMP is a significant component of the Stormwater Pollution Prevention Plan (SPPP), which
is a requirement under this permit and consistent with the written stormwater management program
document required by 40 CFR 122.34(b).
11
The Stormwater Management rules at N.J.A.C. 7:8 define what constitutes new development and
redevelopment projects. The Stormwater Management rules at N.J.A.C. 7:8-5 also establish the
stormwater management design and performance standards for water quality, water quantity,
groundwater recharge, and green infrastructure. The design and performance standards of the
Stormwater Management rules are implemented for major development by the municipalities under the
authority of Municipal Land Use Law (N.J.S.A. 40:55D-1 et seq.) through the municipalities’
stormwater control ordinances adopted with the MSWMPs. Furthermore, the design and performance
standards of the Stormwater Management rules are incorporated by reference in the Residential Site
Improvement Standards (RSIS, N.J.A.C. 5:21- 7), which apply to residential developments. In addition
to implementation through the municipality’s land use approval, the design and performance standards
of the Stormwater Management rules are implemented by the Department through the review of permits
issued by the Division of Land Use Regulation (Flood Hazard, Freshwater Wetlands, Coastal Area
Facility Review Act (CAFRA), Waterfront Development, Coastal Wetlands, and Highlands Water
Protection and Planning).
The Stormwater Management rules require applicants for major development to minimize the impacts
of development on water quality, quantity (flooding), groundwater recharge and through the use of
green infrastructure. “Green infrastructure” is defined at N.J.A.C. 7:8-1.2 to mean stormwater
management measures that manage stormwater close to its source either by stormwater runoff treatment
through infiltration into subsoil, treatment by vegetation or soil, or storage for reuse. The Stormwater
Management rules under N.J.A.C. 7:8 overall implement various water quality, water quantity, and
groundwater recharge design and performance standards intended to provide water quality treatment
for total suspended solids (TSS) and nutrients, prevent increases to flooding and erosion, and prevent
the depletion of aquifers and base flow of watercourses, respectively.
D. Regulation of Groundwater
This permit authorizes all new and existing stormwater discharges to surface water or ground water
from small MS4s owned or operated by Tier A Municipalities. To the extent that the permit regulates
underground injection, the permit also implements EPA’s regulations (found mainly at 40 CFR144-
148) for the Federal Underground Injection Control (UIC) Program. The UIC Program was created
pursuant to Part C of the Federal Safe Drinking Water Act (42 U.S.C. 300f et seq.). EPA recognizes
that States issue general as well as individual permits to regulate Class V injection wells (see 64 Fed.
Reg. 68554 (December 7, 1999), 67 Fed. Reg. 39590 (June 7, 2002), and the Class V Underground
Injection Control Study, Volume 1 (see
www.epa.gov/uic/class-v-underground-in
jection- control-
study). UIC is also covered in the NJPDES Regulations at N.J.A.C. 7:14A-8.
A. 2004 Tier A MS4 NJPDES Permit
New Jersey first issued the Tier A MS4 NJPDES Permit in 2004 consistent with the requirements of
N.J.A.C. 7:14A-25.6. This permit included the below listed Statewide Basic Requirements (SBRs) and
related best management practices (BMPs) that were designed to achieve the Federal Six Minimum
Measures discussed in Section 2, Federal Stormwater Regulations above. These permit requirements
were prescriptive in nature to aid in implementation where compliance of SBRs and related BMPs must
be detailed in the municipality’s SPPP. A summary of SBRs as included in the 2004 Tier A NJPDES
Permit included the following:
Public Notice for public participation in the development of Tier A Municipality stormwater
4. Tier A MS4 NJPDES Permit History
12
programs;
Post-Construction stormwater management in new development and redevelopment;
Local public education;
Ordinances addressing improper disposal of waste;
Illicit connection elimination and MS4 outfall pipe mapping;
Solids and floatable controls;
Municipal maintenance yard operations;
Employee training; and
Construction site stormwater runoff control.
The 2004 permit also included a provision for additional measures. Pursuant to N.J.A.C. 7:14A-25.6(e),
additional measures are non-numeric or numeric effluent limitations that are expressly required to be
included in the stormwater program by an areawide or Statewide water quality management plan as
adopted in accordance with N.J.A.C. 7:15. Additional measures could also be required by the
Department based on an adopted Total Maximum Daily Load (TMDL) approved or established by
USEPA, or an equivalent analysis that determines such additional measures are needed to protect water
quality, or a regional stormwater management plan adopted under N.J.A.C. 7:8. For additional
measures other than numeric effluent limitations, the areawide or Statewide WQM plan shall specify
the BMPs that the permittee or another entity (see N.J.A.C. 7:14A-25.6(a)3 or 25.8(e)) will implement
along with the measurable goals for each of those BMPs.
The 2004 permit also included a provision for optional measures. Optional measures are BMPs that are
included at the municipality’s discretion (in addition to any other permit requirements) that are intended
to further prevent or reduce pollution of the waters of the state pursuant to N.J.A.C. 7:14A-25.6(i). In
the case of optional measures, the SPPP shall specifically identify such BMPs as optional measures and
identify actions to implement those optional measures.
B. 2005 Tier A MS4 NJPDES Permit Modification
The Department issued a modification to the 2004 permit to further develop and refine certain aspects
of the permit. This included the following changes:
Expanded the scope of non-stormwater discharges allowable to include rinsing and wash water
from certain activities;
Established a definition of “catch basin”;
Revised requirements within the Post-Construction Stormwater Management in New Development
and Redevelopment section;
Revised the Yard Waste Ordinance / Collection Program to provide Tier A Municipalities with
additional flexibility on yard waste collection; and
Established an Equipment and Vehicle Washing permit requirement.
C. 2009 Tier A MS4 NJPDES Permit
The permit was renewed in 2009. A summary of the most significant changes included in the 2009
permit are itemized below:
Established a definition for “Permanent Structure” to clarify eligible structures for De-Icing
Storage;
Established a point system for the Local Public Education Program;
Removed the 7-day requirement from the Yard Waste Collection Program and Ordinance;
13
Required adoption and enforcement of a Fertilizer Management Ordinance for select
municipalities;
Required adoption and enforcement of an ordinance mandating the retrofitting of storm drain inlets
by private entities when repaving parking lots or private roads;
Required adoption and enforcement of an ordinance requiring certain private dumpsters and refuse
containers to be covered and leak proof;
Removed the Road Erosion Control BMP requirement;
Clarified the storm drain inlet retrofitting permit requirement to specifically state that “resurfacing
(including top coating or chip sealing with asphalt emulsion or a thin base of hot bitumen)” is
repaving;
Revised the Solids and Floatables Control permit requirement so that catch basin cleaning becomes
a separate BMP with a schedule for catch basin inspection and cleaning;
Required permittees to record where and when vehicle and equipment washing activities occur;
Refined the language within the minimum standard of the Employee Training BMP; and
Required revision of the SPPP on or before June 1, 2009 to incorporate the changes required by the
2009 renewal.
D. 2018 Tier A MS4 NJPDES Permit
The permit was renewed again in 2018. A summary of the most significant changes included in the
2018 permit are itemized below:
The structure of the permit was reorganized and revised from a single Part I narrative style permit
in the 2009 renewal, to a multiple part permit in order to separate the broadest requirements from
the most specific in an effort to improve readability, clarity, and enforceability. These new parts
were:
o Part I General Requirements: NJPDES which lists broad citations applicable to all NJPDES
Permits;
o Part II General Requirements: Discharge Categories which provides general permit
requirements that are applicable only to this permit category (e.g., Eligibility, Administrative
Process and General Conditions);
o Part III Recordkeeping and Reporting which states the general obligation to maintain records
and report compliance status in the Annual Report and Certification;
o Part IV Specific Requirements: Narrative - Notes and Definitions which provides notes and
definitions including a list of acronyms used in Parts I through IV. References in this fact sheet
and within this permit to Part IV “Notes and Definitions” are preceded with the words “Notes
and Definitions” (e.g., Notes and Definitions Part IV.A.1); and
o Part IV Specific Requirements: Narrative - Tier A Municipal Stormwater General Permit which
includes a general overview and the specific requirements which a permittee was required to
meet in order to remain in compliance with the permit. References to Part IV “Tier A Municipal
Stormwater General Permit” are, for the sake of brevity, not preceded by descriptive text (e.g.,
Part IV.A.1).
Two new sections were added to Notes and Definitions, Part IV.A.3 and 4, which are intended to
provide the permittee with a ready reference to state and Federal guidance documents. A list of
acronyms was added, and changes were made to some definitions. The Department added new
definitions; modified definitions found in the 2009 permit; and removed one definition found in the
2009 permit;
New definitions were added for the following terms: “Green infrastructure”, “Maintenance Plan”,
“Major Development”, “Manufactured treatment device”, “Storm drain inlet”, "Stormwater
14
management basin", “Stormwater management measure”, “Stream scouring”, “Subsurface
infiltration/detention system”, “Tier A Municipality’s MS4”, “Wood waste”, and Yard trimmings”.
Modifications were made to the definitions for the following terms: “Existing Permittee”, “Illicit
connection”, “Municipal separate storm sewer”, “New permittee”, “Permanent structure”, “Small
MS4”, “Solids and floatable materials” and “Stormwater facility.”;
The definition of “Original EDPA” is removed since it is not used in this draft permit renewal as it
was intended for the first iteration of the permit as issued in 2004. Finally, the definition for “MS4”,
which was only the description of an acronym, has been removed from the definition section and
moved to the new list of acronyms;
Eliminated the formula of Minimum Standard, Measurable Goal, and Implementation schedule
found throughout Part I of the 2009 permit and only stated Minimum Standard in the body of the
permit;
Renamed the first permit requirement from the 2009 permit “Public Notice” to “Public Involvement
and Participation Including Public Notice” to align with the Federal minimum control measures
more closely;
Renamed the second permit requirement from the 2009 permit “Local Public Education” to “Local
Public Education and Outreach” to align with the Federal minimum control measures more closely;
Expanded local public education point system to include activities or events under five categories
and increased the amount of required points from 10 to 12;
Includes new Part IV.A.3.e requiring the permittee to modify its stormwater program within one
year of any notification by the Department that such a change is necessary;
Made the refuse container/dumpster ordinance optional;
Removed the requirement for the fertilizer management ordinance;
Added additional BMPs to be implemented at the maintenance yard for various activities
(inspections and good housekeeping, fueling operations, discharge of stormwater from secondary
containment, vehicle maintenance, equipment and vehicle washing and wash wastewater
containment, salt and de-icing material storage and handling, aggregate material storage, street
sweepings, catch basin clean out and other material storage, yard trimmings and wood waste
management sites); and
Added the Stormwater Management Design Review (SWMDR) training requirement and
municipal board and governing body member related training requirement.
The final 2018 Tier A MS4 permit renewal was subsequently appealed following its issuance on
November 9, 2017. More specifically, the Delaware Riverkeeeper Network and Stony Brook-Millstone
Watershed Association, Save Barnegat Bay, Raritan Headwaters Association, NY/NJ Baykeeper,
Hackensack Riverkeeper, Association of New Jersey Environmental Commissions filed an appeal of
the November 9, 2017 NJPDES permit with the Appellate Division of the New Jersey Superior Court.
The New Jersey Appellate Division issued an opinion, Delaware Riverkeeper Network and Maya Van
Rossum, Delaware Riverkeeper v. NJ Department of Environmental Protection, Docket A-001821-
17T3 and A-1889-17T3, on March 18, 2020 affirming the NJPDES MS4 permit.
E. Proposed Tier A MS4 NJPDES Master General Permit Renewal
This subject draft Tier A MS4 NJPDES permit action serves to renew the 2018 Tier A MS4 NJPDES
permit. This Tier A MS4 NJDPES master general permit is proposed to be renewed and a summary of
the most significant changes proposed are listed below, with a detailed explanation of each of these
changes in Section 7 of this fact sheet below:
Requiring all (including new) Tier As to develop a Watershed Improvement Plan (“WIP”) in stages
over the 5-year permit term to address water quality impairments, TMDLs & protect high quality
15
waters;
Requiring mapping of all MS4 stormwater infrastructure;
Removing authorizations for leaf composting operations at municipal maintenance yards under the
Tier A, and require authorizations under the new Wood Waste Recycling & Leaf Compost General
Permit to be issued concurrently with the Tier A renewal;
Increasing street sweeping from monthly on some town roads - to all town roads 1-3 times per year,
depending on presence of storm drain inlets;
Requiring the review of de-icing additive ingredients;
Requiring towns to finish storm drain inlet retrofits by end of the 5-year permit cycle;
Adding a minimum inspection frequency for public and private BMPs to ensure proper
maintenance;
Adding a requirement for towns to require commercial/industrial facilities to cover salt piles year-
round when not in use (such as mall parking lots);
Requiring enhanced Best Management Practices at Municipal Maintenance Yards - will require
covering of additional types of materials stored in the yards & include links to the Wood Waste
Recycling & Leaf Compost General Permit;
Requiring removal of piles of excess residual salt on roads/parking lots deposited during spreading
operations;
Requiring measurable time frames for stream scouring and illicit connection program remediation;
Requiring towns to establish a dedicated stormwater webpage (we have a template posted on our
webpage which has already been used by some towns );
Increasing frequency of some employee stormwater training to annual to be reflective of annual
SPPP updates;
Adding the road erosion sediment control requirement back into the permit; and
Enhancing the SWMDR training requirement to require a short update course to cover rule
amendments.
It should also be noted that the five attachments to the 2018 permit have been revised. These changes
are summarized below with additional descriptions included in Section F:
Attachments A and A-1 - Measurable Goals and Implementation Schedule, which reiterated many
of the permit requirements in tabular form and included due dates for existing permittees and new
permittees, respectively, has been removed and all permit requirements from this attachment have
been incorporated throughout the body of the permit;
Attachment B - Point System for Public Outreach and Education has been revised to remove points
for creating a dedicated stormwater webpage, as well as other minor updates, and is now
Attachment A;
Attachment C - Design Standards for Storm Drain Inlets has been revised slightly to remove the
reference to the netting facility and is now Attachment B;
Attachment D Major Development Stormwater Survey, has been removed from the permit, and
now a revised version of that form is required to be submitted with the Supplemental Questionnaire
with each Annual Report;
Attachment E Best Management Practices for Municipal Maintenance Yards and other Ancillary
Operations, has been removed and all permit requirements from this attachment have been
incorporated into the body of the permit.
F. Compliance Assistance and Stakeholder Outreach for the Current 2023 Permit Renewal
In an effort to improve overall effectiveness of the permit renewal process and to maximize stakeholder
input, the Department held three virtual preliminary outreach sessions in August of 2021:
16
MS4 Permit Renewal Preliminary Outreach
Meeting Dates
MS4 Outreach – South
8/25/2021
MS4 Outreach – Central
8/26/2021
MS4 Outreach – North
8/31/2021
These preliminary outreach sessions were held to explain and gather feedback about potential new MS4
permit renewal conditions to address current water quality concerns, including TMDLs and water
quality impairments. The invitations to these sessions were emailed on August 6, 2021, to the
Stormwater Program Coordinators of the 456 Tier A municipalities and 101 Tier B municipalities.
These invitations were also open to each municipality’s respective consultants as well. Invitations were
also sent to 92 interested parties, including various environmental groups. A total of 122 people
attended these sessions, some of whom attended more than one session, and some consultants
represented multiple towns. Requests were received to address the following various stormwater
related topics:
Enhance the stormwater management measure BMP inventory, maintenance, inspection, and
enforcement requirements;
Require the retrofitting of existing development with stormwater management BMPs;
Ensure that the permit requires permittees to conduct meaningful public outreach;
Require annual updating of contact information in SPPP’s to maintain continuity through municipal
staff turnover;
Consider making funding available and what the cost associated with compliance with new or
revised permit requirements would be;
Consider climate change related concerns including data collection and costs incurred by
municipalities due to the impacts of climate change such as increased flooding and sea level rise;
Require improved personnel training, including better online stormwater training, and requiring
operator licenses for storm sewer operators; and
Incorporate enhanced TMDL considerations into local stormwater management planning,
including pollution reduction targets and water quality monitoring.
The Department then prepared a pre-draft of the permit renewal, which was emailed on March 2, 2022,
to the Stormwater Program Coordinators of the 456 Tier A towns, 101 Tier B towns, and 63 interested
parties, and scheduled the following virtual outreach sessions. Emails including the pre-draft permit
were also sent to the mayors of all Tier A and Tier B towns.
MS4 Permit Renewal Pre-Draft Outreach
Meeting Dates
MS4 Outreach 1
3/22/2022
MS4 Outreach 2
3/24/2022
Emails went to fewer members of interested parties for the March outreach sessions based on the
undeliverable and returned emails from the August outreach. A total of 71 people attended these
sessions, representing at least 53 Tier A municipalities, an unknown number of Tier B municipalities,
12 interested parties, and 3 phone-in attendees of unknown affiliation.
During the March 2022 outreach sessions, the Department received the following questions and
comments:
Will the ordinances requiring covering of private salt storage and tree removal also require an
17
enforcement component by the municipalities and will the Department provide models of these two
new ordinances?
Clarify the following issues regarding the Watershed Improvement Plan (WIP):
o Will the development of a WIP make towns eligible for 319(h) funding and are public-private
partnerships an option for funding of the WIP?
o Will the Watershed Improvement Plan require towns to achieve the percent reductions
specified in each TMDL and will TMDLs be revised to include other contaminants such as
microplastics or PFAS?
o Will towns be required to incorporate existing Watershed Restoration Plan recommendations
into the WIP and can municipalities take a regional/watershed-based approach to the WIP?
o How are the pollutant reduction goals of the Watershed Management Plan determined, and how
do they correlate to the TMDL percent reductions?
o As part of the Watershed Inventory Report for the WIP, the permittee must submit an electronic
map of overburdened communities and prioritize the needs of overburdened communities in
the final WIP. Hasn't NJDEP already developed a GIS layer that provides a determination of
overburdened communities and can be used for this?
o Does the requirement to map storm drain inlets just apply to inlets that are owned/operated by
permittee and what satisfies the location requirement?
o Provide clarification on what sort of timeline municipalities should be considering when they
think about watershed improvements? For example, should municipalities be implementing
these improvements over 10 years? 20 Years?
Clarify if Stream Scouring and erosion happen to sections of streams or other waterbodies not near
a municipal outfall, does the permit still require streambank stabilization :
Provide direction/clarification on what to look for during Illicit Discharge Detection & Elimination
inspections, how to request an extension for illicit discharge remediation after month 11, and will
the Department have an ultimate deadline for illicit discharges to be remediated.
Clarify if the Mapping of Stormwater Facilities include all outfalls or just outfalls that discharge
directly to surface water and whether it applies to privately owned stormwater management
facilities as well.
Provide clarification on whether the new Storm Drain Inlet Retrofit requirement is required for
privately owned storm drain inlets? And can this requirement be moved under the WIP section of
the permit.
Are Optional Measures being removed from the permit renewal and if so, can they be put back?
The Residential Site Improvement Standards (RSIS) has no grounds to regulate stormwater
statewide and references should be removed from the permit.
The Department explained during the outreach sessions that we will provide model language for both
the Privately-Owned Salt Storage Ordinance and the Tree Removal/Replacement Ordinance.
Municipalities will need to adopt the ordinances and establish an enforcement policy, though the
improper storage of salt on private properties that results in illicit discharge to stormwater may already
be enforced through the Illicit Connection Ordinance which is a condition of the 2018 permit.
While some stakeholders were pleased to see the addition of a Watershed Improvement Plan in the
MS4 permit, particularly given the potential to improve local water quality and flooding problems,
other participants were concerned about funding. They asked if the formation of a Stormwater Utility
would be an appropriate source of funds and/or if there would be grant money available to fulfill the
requirements in the Watershed Improvement Plan and other permit conditions that pose budgetary
concerns for municipalities to be compliant. Discussion followed to advise that 319(h) grants may be
available for projects involving green infrastructure and that Stormwater Utility fees would also be an
18
appropriate source of funding. Some stakeholders asked if it is required to incorporate existing
watershed restoration plans. The Department advised that this would be encouraged but is not required,
as is collaborating with neighboring municipalities to establish a regional approach. For stakeholders
who expressed strong interest in being involved in municipalities’ Watershed Improvement Plans, the
Department noted that there will be a 60-day public comment period for each report/phase of the
development of plans and for each project thereafter, and that it is open for anyone to participate.
A stakeholder asked if existing developments could be included in the retrofits of storm drain inlets and
the Department advised that the municipality is already required under the 2018 Tier A permit to adopt
and enforce an ordinance requiring the retrofitting of existing storm drain inlets on private property but
may also choose to include additional private storm drain inlet retrofitting requirements as part of their
Watershed Improvement Plan.
Stakeholders asked a few questions regarding clarification of the stormwater infrastructure mapping
requirements. It was clarified that under this permit, mapping is only required to be completed by the
municipality and not by private entities since they are not MS4 permittees. However, private stormwater
infrastructure is required to be included on the permittee’s maps as part of the Watershed Improvement
Plan. A stakeholder asked if green infrastructure is required to be mapped and it was clarified that all
stormwater facilities are required to be mapped and that green infrastructure falls under the definition
of a stormwater facility.
Optional Measures were removed from the pre-draft Tier A renewal permit and a commenter requested
that it to be added back into the permit. It was answered that it was taken out as there is no restriction
on the town being able to adopt Optional Measures. It was also discussed that Optional Measures are
not enforceable by DEP. However, in response, the Department has added this section back into the
permit renewal.
A commenter requested that references to RSIS be deleted and to also include language that references
the Clean Water Act and the New Jersey Pollutant Discharge Elimination System (NJPDES) rules to
make it clear that the goal is to improve water quality.
The Department received 21 comments from the USEPA, which are summarized here:
Include definitions for measurable goal, surface water body, and waters of the State;
Make language in certain sections of Part IV more clear, specific, and measurable;
Include publicly-owned green infrastructure in the Infrastructure Map;
Require proposed changes to the MSWMP be reviewed by the county planning agency before local
adoption;
Add additional specifications to catch basin inspection requirements and catch basin cleaning;
Do not rely on fluoride concentrations as an indicator in the Illicit Connection Report Form and
guidance as most of New Jersey’s water supplies are not fluoridated;
Clarify if the permittee will need a map of drainage areas to each outfall for identifying sources of
stormwater that contribute to scouring;
EPA supports the improved TMDL language requiring permittees to know the TMDLs associated
with their MS4s and develop a plan to meet their TMDLs;
Add details on how the Watershed Improvement Plan section includes waste load allocations;
Define “overburdened communities” or provide a method for permittees to determine such
communities (i.e., with use of NJ State environmental justice GIS maps);
The Department also received 575 emailed comments from various stakeholders, including
19
municipalities, environmental groups, and other individuals. Many of these comments were similar to
those received during the two outreach sessions in March 2022, while comments on additional topics
were also received, including:
Provide clarification to the statement in Part IV.E.1.i. that RSIS only applies to areas in the
municipalities that contribute stormwater to ‘eligible stormwater discharges;’
Consider that vegetation, terrain, density and other factors are so different between communities in
the southern, central and northern regions, that the concept of one Tree Ordinance for all is
unrealistic;
Support for the water quality related requirements pertaining to impairments and TMDLs;
Provide clarification that the Stormwater Program Coordinator must be duly appointed or
authorized by such;
Amend Part IV.A.1.f. to include an additional statutory citation that Master Plans shall include
MSWMPs;
Suggested the removal of references to “STORMWATER UTILITY” from the permitting language
at Part IV.A. 3.a; and
Recommended the inclusion of a compliance schedule in Part IV.G.2 or 3 and extending the
deadline for expansion of permittees’ illicit connection programs to include stormwater outfalls
that are not pipes.
The Department also held many earlier stakeholder outreach sessions during the preparation of the
March 2, 2020, amendments to the Stormwater Management rules at N.J.A.C. 7:8 and formed
subgroups to address some of the remaining issues that were brought up by stakeholders but were
outside the scope of the Stormwater Management rules amendments being discussed at that time. One
of the subgroups that was formed, the TMDL subgroup, focused on how the Department should address
stormwater discharges to waters that are subject to TMDLs. The subgroup consisted of stakeholders
representing developers, consultants and environmental groups, including three of the environmental
groups that appealed the 2018 MS4 renewal. See Delaware Riverkeeper Network v. New Jersey
Department of Environmental Protection, Dkt. A-1821-17T3). Although consensus was not reached in
the subgroup, one of the requests of the environmental groups was to enhance the protection of surface
waters that were impaired or the subject of an approved TMDL from pollutants in municipal stormwater
discharges.
Additionally, the USEPA submitted the following comment in response to the issuance of the draft
2018 permit renewal:
Please explain how municipalities will evaluate the impact of direct discharges on downstream
water quality and track their progress in reducing stormwater loadings for waters with a TMDL,
that are listed as impaired, that are on the state’s 303(d) list, or have in place other pollutant
reduction plans approved by NJDEP. EPA suggests considering requiring a modest level of
municipal outfall monitoring in the MS4 permit similar to Connecticut’s MS4 program as noted at
the following website:
http://www.ct.gov/deep/lib/deep/Permits_and_Licenses/Water_Discharge_General_Permits/MS4
_gp.pdf.
EPA also suggests cooperation with, where available, active citizen and non-government
organization water quality monitoring programs which can furnish valuable information if provided
guidance by NJDEP.”
20
The USEPA also provided the following recommendation in the National Pollutant Discharge
Elimination System Permit Quality Review report for New Jersey, performed by USEPA Region 2 and
dated September 7, 2017.
Stormwater-
Tier A MS4
NJDEP should strengthen the TMDL requirements in the permit to ensure that
stormwater WLAs will be complied with in order to be consistent with EPA
regulations at 40 CFR §122.44(d)(1)(vii)(B).
The USEPA Permit Quality Reviews (PQR) consist of evaluations of select sets of NPDES permits to
determine whether permits are being developed in a manner consistent with applicable requirements
established in the Clean Water Act (CWA) and NPDES regulations. Through this review mechanism,
the USEPA promotes national consistency, identifies successes in implementation of the NPDES
program, and identifies opportunities for improvement in the development of NPDES permits. The
USEPA conducted the review of the New Jersey State Pollutant Discharge Elimination System
(NJPDES) permitting program, which included desktop permit reviews and an on-site visit to the
Department’s offices in Trenton, NJ, on May 31 and June 1, 2016. While this review was conducted
prior to the issuance of the 2018 permit, the PQR report was not received by the Department until
September 7, 2017. This was well after the issuance of the 2017 draft permit renewal and would have
delayed the renewal of the final 2018 permit renewal which had been expired since 2014 and would
have constituted a significant change between draft and final permit issuance requiring preparation of
a new draft permit and a new public comment period, further delaying the issuance of the renewal.
Therefore, the Department opted to finalize the draft permit and evaluate various methods to address
TMDLs for consideration in the following permit renewal. The Watershed Improvement Plan, detailed
in Section H of this fact sheet, is the method by which the Department has chosen to address TMDL
requirements, as well as concerns regarding other impaired waters.
The Department has created a multitude of resources, including guidance documents, checklists, and
training modules to assist with compliance with the current permit and is working to update many of
these documents for this renewal as well. The Department maintains that these resources will assist
municipalities to implement compliant MS4 stormwater programs which will positively impact water
quality. Resources for Tier A Municipalities are available at www.nj.gov/dep/dwq/tier_a.htm
and links
are provided within this draft permit in Part IV. Additionally, the Department has posted a stormwater
index at
www.state.nj.us/dep/dwq/fd.htm which guides stormwater management professionals,
permittees and the general public to the Department's stormwater related technical information,
guidance materials, educational resources, forms, and applications.
As stated in the fact sheet of the 2018 MS4 permit renewal, “…the Department is engaged in an
assessment of and improvements to its municipal stormwater program which includes efforts to better
gauge the effectiveness of the MS4 program. These efforts include development of a new Supplemental
Questionnaire relative to the annual report form and a stormwater audit process intended to provide
focused compliance assistance to municipalities. These efforts will provide a platform for discussion
between municipalities and Department staff to foster an adaptive approach to municipal stormwater
management planning.
In implementing the improvements discussed above, the Department conducted 58 Compliance
Assistance Audits of Tier A municipalities’ stormwater programs and developed other documents and
templates to assist municipalities in complying with their permit requirements. These other materials
include an SPPP template that follows the 2018 permit outline, and which will be updated to follow
this permit renewal as well. The Department also created a stormwater webpage template so towns
could consolidate all of their stormwater related materials, or links to those materials, on one page.
Stormwater outfall inspection forms for general inspections, illicit connection inspections and stream
21
scouring inspections have been developed and posted on the webpage as well. These and other
stormwater related materials are posted at www.nj.gov/dep/dwq/msrp_home.htm.
A. Regulatory Background
Pursuant to N.J.A.C. 7:14A-25.3, Tier A Municipalities include those New Jersey municipalities that
are:
Located entirely or partially within an urbanized area and have a population of at least 1,000 within
the urbanized area (as defined by the latest Decennial Census);
Have a population density of at least 1,000 per square mile and a population of at least 10,000 as
determined by that Census;
Have a stormwater sewer system discharging directly into the salt waters of Monmouth, Ocean,
Atlantic, or Cape May counties;
Request to be Tier A; or
Operates a stormwater discharge(s) identified under N.J.A.C. 7:14A-25.2(a)4 (special
designations), provided that the Department determines that such identification warrants
assignment of the municipality to Tier A.
There is a separate MS4 NJPDES permit for Tier B Municipalities which was renewed concurrently
with the Tier A renewal in 2018 and is available at www.state.nj.us/dep/dwq/tier_b.htm.
T
he Tier B
permit is a subset of the Tier A permit where fewer requirements apply. Permittees and interested parties
should refer to the complete text of the Tier B permit for those requirements. In general terms, the
current Tier B MS4 NJPDES permit includes requirements pertaining to: Post Construction Stormwater
Management in New Development and Redevelopment (including proper operation and maintenance
of stormwater facilities), Local Public Education; and the labeling and design of storm drain inlets. The
Tier B permit is not being proposed for renewal at this time as all 101 current Tier B municipalities
have been notified by letter dated July 1, 2022, that they are being reassigned to Tier A, which is
planned to occur simultaneously with the renewal of this Tier A renewal permit. However the current
Tier B permit can be found at
www.state.nj.us/dep/dwq/tier_b.htm. The Tier B permit is not in any
respect a NPDES permit under section 402 of the Clean Water Act (see N.J.A.C. 7:14A-25.8(a)).
B. Issu
ance of Authorizations to Tier A Municipalities
Upon completion of the public comment and public notice process pursuant to N.J.A.C. 7:14A-16.4,
the Department will make a determination whether to finalize this permit. If finalized, the Department
will then issue this Master General Permit as well as the individual authorizations to each eligible Tier
A Municipality in accordance with N.J.A.C. 7:14A-6.13.
C. Tier Assignment
The current designation of Tier A or Tier B municipalities was based on the 2000 Decennial Census.
A listing of Tier A Municipalities is located at www.nj.gov/dep/dwq/msrp_home.htm co
nsistent with
N.J.A.C. 7:14A-25.3(a)3. Although the Census was updated in 2010, no reassignments were made in
accordance with the criteria under N.J.A.C. 7:14A-25.3 during the term of the 2009 or 2018 MS4
general permits.
A
s noted above, the Department has notified each of the 101 current Tier B municipalities that they are
5. Identification of Tier A Municipalities
22
being reassigned to Tier A, along with information regarding the justification and submission
requirements for a Request for Authorization (RFA) under this permit. Municipalities that received
this notice from the Department pursuant to N.J.A.C. 7:14A-25.2(e) and/or N.J.A.C. 7:14A- 25.3(a)3
were advised the deadline to submit the RFA under the Tier A permit is 180 days after the receipt of
that notice. This Tier A permit renewal contains compliance schedules for new permit requirements for
new Tier A permittees that will be required to enhance their stormwater programs. The specific
compliance schedule due dates are noted under each permit condition in Section 7 below. Although
reassignment from Tier B to Tier A is being done concurrently with this renewal, reassignment is
neither part of the Tier A renewal nor subject to public comment, consistent with N.J.A.C. 7:14A-25.3.
A. Overview
The Tier A Municipality (i.e., the permittee) is required to develop, update, implement and enforce an
MS4 stormwater program. A primary objective of the MS4 stormwater program is for permittees to
implement best management practices (“BMP’s”) and other control measures to implement the
Statewide Basic Requirements (N.J.A.C. 7:14A-25) and other permit requirements set forth in the
permit. The permit requirements serve to reduce the discharge of pollutants from the Tier A
Municipality’s MS4, municipal maintenance yards and other ancillary operations to the maximum
extent practicable pursuant to N.J.A.C. 7:14A-25.6(a)1 and 40 CFR 122.34(a), to protect and restore
water quality, and to satisfy the applicable water quality requirements of the Clean Water Act.
The Stormwater Pollution Prevention Plan (SPPP) documents the Tier A Municipality’s stormwater
program and describes the measures necessary for each municipality’s compliance with the Statewide
Basic Requirements as well as any Other Control Measures, Optional Measures and Additional
Measures. The Tier A Municipality shall submit an Annual Report and Certification summarizing the
status of compliance with this permit. See Part IV.K (Annual Report and Certification).
Part IV.E.2 of this permit and N.J.A.C. 7:8-4.3(a) require the municipality to develop a Municipal
Stormwater Management Plan (MSWMP.) The MSWMP describes the municipality’s strategy,
structure, and process for addressing stormwater runoff from new development and redevelopment to
ensure compliance with the Stormwater Management rules (N.J.A.C. 7:8.) This strategy, structure and
process constitute much of the post construction stormwater management program in this permit. The
MSWMP is also a component of the municipal master plan (N.J.S.A. 40:55D-94) and the municipality’s
SPPP must be consistent with its MSWMP.
B. Use of Best Management Practices to Reduce Pollutants to Maximum Extent Practicable
Consistent with the EPA Phase II stormwater rules for small MS4s, the NJPDES regulations at N.J.A.C.
7:14A-25 outline in broad terms what must be included in NJPDES MS4 permits. Beginning with the
issuance of the 2004 MS4 NJPDES permits, the Department has been prescriptive in its approach to
defining permit conditions. This is partly due to the fact that state and Federal regulations (N.J.A.C.
7:14A-25.6(a)1 and 40 CFR 122.34(a)) stipulate that compliance with the standard of reducing
pollutants to the maximum extent practicable is accomplished through the implementation of BMPs or
control measures. This draft permit is a Comprehensive General Permit (under 40 CFR 122.28) which
requires permittees to develop, update, implement and enforce a stormwater program (as documented
in an SPPP) to ensure compliance with Statewide Basic Requirements (SBRs), the actions developed
to implement the six Federal Minimum Measures, as well as any Optional Measures, Additional
Measures and other permit requirements. The Department provides an appropriate level of specificity
in establishing Tier A NJPDES MS4 permit conditions by specifying BMPs, measurable goals through
6. Overview of Tier A MS4 NJPDES Permit Requirements
23
the detailed permit requirements, and implementation schedules for these permit requirements and other
measures. This provides permittees, the public and regulators with clarity regarding what
municipalities must do to comply with the permit.
Without specific conditions, this permit would be difficult to enforce and would give permittees little
direction as to how to meet the requirements of State and Federal Rules. The Department has taken care
to issue specific MS4 permit conditions with clear stormwater program requirements since 2004 in
order to establish a standard of compliance rather than requiring New Jersey’s current 456 Tier A
municipalities, and new 101 Tier A municipalities to independently create compliance conditions for
public and Department individual review and approval.
The Department is not requiring numeric effluent limitations in this draft permit which is consistent
with the Federal Clean Water Act and EPA Phase II regulations at 40 CFR Part 122. The Federal Clean
Water Act defines the term “effluent limit” broadly to include BMPs that would restrict the quantities,
rates, and concentrations of constituents within a discharge. Thus, BMPs provide treatment pursuant to
the Department’s authority under the Clean Water Act with the goal of meeting water quality standards.
Specifically, Section 402(p)(3)(B)(iii) of the Clean Water Act requires that permits for discharges from
municipal storm sewers require:
“…controls to reduce the discharge of pollutants to the maximum extent practicable, including
management practices, control techniques and system, design and engineering methods, and such
other provisions as the Administrator or the State determines appropriate for the control of such
pollutants.”
Similarly, inclusion of best management practices as effluent limitations is also consistent with the
NJPDES Regulations at N.J.A.C. 7:14A-25.6(a)1 which states:
“Best management practice (BMP) requirements are generally the most appropriate form of
effluent limitations when designed to satisfy technology-based requirements (including reductions
of pollutants to the maximum extent practicable) and to protect water quality. Implementation of
BMPs (other than OMs [Optional Measures]) consistent with the provision of the stormwater
program required … and the provisions of the NJPDES permit … constitutes compliance with the
standard of reducing pollutants to the maximum extent practicable.”
In accordance with 40 CFR. 122.34(a), the Department must “include terms and conditions that meet
the requirements of this section based on its evaluation of the current permit requirements, record or
permittee compliance, and program implementation progress, current water quality conditions, and
other relevant information.” Continued efforts by the Department’s Municipal Stormwater Regulation
Program, including review of compliance evaluations, Annual Reports and Certifications, and
Supplemental Questionnaires; outreach efforts; and implementation of a municipal stormwater program
audit process, constitute evaluation of the permit requirements and the progress of municipal
stormwater programs. Based on the Department’s evaluations of current municipal stormwater
programs, the requirements contained in this permit renewal have been developed to account for the
information gathered since the issuance of the 2018 Tier A MS4 NPDES permit. The requirements
included in this permit constitute the Department’s determination of reasonable progress toward
reducing pollutant discharges to the maximum extent practicable.
Any municipality authorized under the 2004 Tier A permit was required to and continues to be required
to develop a stormwater program. The Tier A permittees’ stormwater programs must be documented
in their respective SPPPs. The SPPPs must be retained on site and made available for review by the
Department. Additionally, a new requirement of this renewal is the requirement for the permittee to
24
submit their SPPP to the Department. To certify compliance with the permit, Tier A Municipalities
complete an Annual Report and Certification which queries specific details regarding the Tier A
Municipality’s stormwater program.
C. Eligible and Ineligible Discharges (Part II.A)
This permit is intended to continue to authorize and control new and existing stormwater discharges to
surface water and groundwater from small MS4s owned or operated by municipalities assigned to Tier
A and from municipal maintenance yards and other ancillary operations owned or operated by Tier A
Municipalities. A NJPDES permit is required for these stormwater discharges under N.J.A.C. 7:14A-
25.2(a) and 24.2(a). Permit conditions regarding eligible stormwater discharges are included in Part
II.A.2.a. Part II.A.2.a includes a specific reference to municipal maintenance yards and other ancillary
operations which is further explained in Section 7.A.5.c, below. However, stormwater discharges from
wood waste recycling and composting activities will not be authorized under this Tier A MS4 permit
renewal; once this permit is final and effective, continued stormwater discharges from these activities
will need to be authorized under the Department’s new Wood Waste Recycling and Leaf Composting
Master General Stormwater Permit.
This permit renewal continues to authorize certain non-stormwater discharges (e.g., certain potable
water sources, uncontaminated groundwater, and irrigation water) from small MS4s owned or operated
by Tier A Municipalities. A complete list of the eligible non-stormwater discharges is included in Part
II.A.2.b of this permit. If any of these discharges are identified by the municipality as a significant
contributor of pollutants, the permittee must address the discharge as an illicit connection or as an
incident of improper disposal of waste (see Part II.A.3.e).
This permit does not authorize “stormwater discharges associated with industrial activity” or
“stormwater discharges associated with construction activity, except as otherwise provided in the
permit in Part II.C. Specifically, in Part II.C.2(a)2, the permit lists activities that commonly occur at
municipal maintenance yards and ancillary operations that are regulated under this permit in Part
IV.F.5. Any permittee that operates an industrial facility or construction site beyond what is specifically
authorized in Part II.C, must obtain a separate NJPDES permit for that discharge. as required in Part
II.C.4. In addition, this permit does not authorize any stormwater discharge that is authorized under
another NJPDES permit so long as that other permit is in effect for that discharge. Also, to implement
statutory and regulatory provisions governing consistency of NJPDES permits with Water Quality
Management (WQM) Plans (e.g., N.J.S.A. 58:10A-6 and 58:11A-10), this permit does not authorize
stormwater discharges from projects or activities that conflict with an adopted WQM Plan.
Statewide Basic Requirements and Associated Conditions
The Tier A permit must address the six Federal Minimum Control Measures under CFR 122.34(b): (1)
Public Education and Outreach on Stormwater Impacts; (2) Public Involvement/Participation; (3) Illicit
Discharge Detection/Elimination; (4) Construction site runoff control; (5) Post-Construction management;
and (6) Pollution Prevention or Good Housekeeping for Municipal Operations and the following Statewide
Basic Requirements (SBRs): (1) Public Involvement/Participation; (2) Construction Site Stormwater
Runoff Control; (3) Post-construction Stormwater Management in New Development and Redevelopment;
(4) Public Education on Stormwater Impacts; (5) Prohibiting Improper Disposal of Waste; (6) Control of
Solid and Floatable Materials; (7) Maintenance Yards and Highway Service Areas; (8) Employee Training.
7. Basis and Background to Tier A MS4 NJPDES Permit Requirements
25
This permit implements the Federal Minimum Control Measures and includes Statewide Basic
Requirements and associated BMPs, consistent with the 2004, 2009 and 2018 Tier A permits. Many
requirements are retained from the 2004, 2009, and 2018 Tier A permits and, for any new requirements in
this permit renewal, the permit provides delayed compliance due dates pursuant to N.J.A.C. 7:14A- 25.6(a)
and (c), to give permittees time to prepare for implementation.
This renewal permit retains the permit requirements as they were restructured to be consistent with the six
Federal Minimum Measures in the 2018 Tier A permit, described in Section 2 of this fact sheet under
Federal Stormwater Regulations, above. A detailed basis and background for each permit requirement, as
well as an explanation of any changes from the 2018 Tier A permit, is included below. A discussion of the
2018 Tier B permit requirements is also included, where applicable.
A. Stormwater Management Program (Part IV.A)
1. Stormwater Program Requirements
This permit renewal, similar to the 2018 Tier A permit, continues to require each permittee to
develop, update, implement, and enforce an MS4 stormwater program in accordance with N.J.A.C.
7:14A-25.6(a), with the primary objective to implement best management practices and other
measures designed to reduce the discharge of pollutants from the permittee’s MS4, municipal
maintenance yards and other ancillary operations to the maximum extent practicable, to protect
water quality, and to satisfy the appropriate water quality requirements of the Federal Act and the
State Act. The permittee will continue to be required to modify their stormwater program to
conform with all applicable new legislation or rule amendments within 12 months from written
notification by the Department. This permit renewal also still requires permittees to document their
stormwater program in a written Stormwater Pollution Prevention Plan (SPPP) as per N.J.A.C.
25.6(a)3, describing the measures necessary for the permittee to comply with each permit
conditions.
The 2018 Tier B permit required each permittee to develop, update, implement, and enforce an
MS4 stormwater program to continue to provide substantial water quality benefits, including an
emphasis on proper operation and maintenance of stormwater facilities to control nutrients,
pathogens, solid and floatable materials, and other pollutants as well as to reduce stormwater runoff
quantity. As per N.J.A.C. 7:14A-25.8(e), the Tier B permittees’ stormwater program was required
to include the Post-construction stormwater management in new development and redevelopment
and the Public education on stormwater impactsStatewide Basic Requirements, as listed in Part
IV.B, as well as any Additional Measures required by Part IV.C of that permit. However, there
were no Additional Measures included in the Tier B permit.
This permit renewal requires a principal executive officer or a ranking elected official to designate
a Stormwater Program Coordinator (SPC) who has the knowledge to manage the implementation
and compliance of the permittee’s MS4 stormwater program as per N.J.A.C. 7:14A-4.9 and
25.6(a)3. As the SPC, this individual is responsible for:
Coordinating the permittee’s implementation of its MS4 stormwater program, permit
conditions, and SPPP;
Signing and dating the SPPP; and
The completion and submittal of the Municipal Stormwater Regulation Program (MSRP)
Annual Report.
Permittees should form a Stormwater Pollution Prevention Team that is made up of individuals
26
responsible for overseeing the implementation of the various permit requirements. Due to the wide
range of tasks required, a variety of municipal personnel should be involved in planning and
implementing the stormwater program. This should include public works officials, municipal
engineer(s), municipal clerks, planning and zoning boards, code enforcement officers, police
officers, and the environmental commissions. Team members are not limited to only municipal
personnel; they could also include local volunteers, members of local watershed associations,
environmental groups, and educational professionals.
If a Stormwater Coordinator assignment changes at any time, a new assignment of responsibility
shall be submitted to the Department within 30 days of such change taking place. This is
accomplished through completion of the online MSRP Annual Report, or the Stormwater Program
Coordinator Information Update Sheet found at https://www.nj.gov/dep/dwq/msrp_home.htm.
The MS4 stormwater program and the SPPP shall be consistent with the Municipal Stormwater
Management Plan (MSWMP), which is a component of the municipal master plan as per N.J.A.C.
7:8-4.3(a). The MSWMP describes the municipality’s strategy for addressing stormwater runoff
from new development and redevelopment to ensure compliance with the Stormwater Management
rules (N.J.A.C. 7:8) and is described in further detail below. It should be noted that both the SPPP
and MSWMP have been requirements since the first iteration of the Tier A permit issued in 2004.
2. Stormwater Pollution Prevention Plan (SPPP) Requirement
The permittee is required to document their municipality’s MS4 stormwater program in their
Stormwater Pollution Prevention Plan (SPPP) as per N.J.A.C. 7:14A-25.6(a)3. This requirement
was originally required in the 2004 Tier A MS4 permit. The SPPP is required to describe how the
permittee will implement each permit requirement and also provides a place for record keeping
documenting when and how permit requirements were met. The SPPP is a living document that is
never “completed. The SPPP shall be reviewed at least annually and updated as often as necessary
to reflect changes related to the municipality’s Tier A MS4 Stormwater Program.
The SPPP shall include information regarding the location of any records required by this permit.
The Department may notify the permittee at any time that the SPPP does not meet one or more of
the permit requirements. Within thirty (30) days after receiving such notification, unless otherwise
specified by the Department, the permittee shall amend the SPPP to adequately address all
deficiencies, and written certification of such amendments shall be submitted to the Department.
The current SPPP shall be posted on the permittee’s dedicated stormwater webpage with updates
posted at least annually thereafter. The version posted on the dedicated stormwater webpage can
exclude inspection logs and other required record keeping. It is advisable for each member of the
Stormwater Pollution Prevention Team or affected municipal employees to have access to the SPPP
for reference and compiling record keeping data.
Existing Tier A permittees will need to update their SPPP to reflect the 2023 permit renewal
conditions by the Effective Date of Permit Authorization (“EDPA”) + 3 months. New Tier A
permittees will have until EDPA + 12 months to create an SPPP.
3. Implementation of SPPP Conditions through Shared or Contracted Services
As allowed in the previous Tier A MS4 permits starting in 2004, the permittee may rely on another
entity (e.g., governmental, stormwater utility, private, or nonprofit organization such as a watershed
association) to satisfy one or more of the permit conditions, or component(s) of any permit
27
condition, provided the other entity implements the contracted services in compliance with the
corresponding permit requirements and agrees to such in writing (See N.J.A.C. 7:14A-3 and 7:14A-
25.7(a)). However, the permittee remains responsible for compliance with the permit conditions if
the other entity fails to implement any of the measure(s) or component(s).
B. Minimum Standards for Public Involvement and Participation Including Public Notice (Part
IV.B)
1. Public Involvement and Participation Including Public Notice
The 2018 Tier A permit renamed this permit requirement “Public Involvement and Participation
Including Public Notice” consistent with N.J.A.C. 7:14A-25.6(b)1 and with the six Federal
Minimum Control Measures at 40 CFR 122.34(b)(2) (see
www.epa.gov/npdes/npdes-stormwater-
program and Section 2, Federal Stormwater Regulations above). In the 2018 Tier A permit
renewal, the Department also consolidated several previous permit requirements within this permit
requirement for clarity and to ensure that applicable public participation and involvement
requirements were met. This permit renewal retains these changes, as follows:
a. The permittee shall comply with applicable State and local public notice requirements when
providing for public participation in the development and implementation of the MS4
stormwater program. Requirements include, but are not limited to:
i. The Open Public Meetings Act (“Sunshine Law, N.J.S.A. 10:4-6 et seq.);
ii. Statutory procedures for the enactment of ordinances (N.J.S.A. 40:49-2); and
iii. The Municipal Land Use Law concerning the adoption or amendment of the MSWMP
(N.J.S.A. 40:55D-13, 28 and 94), and the review of applications for development
(N.J.S.A. 40:55D-12).
b. The permittee shall maintain records necessary to demonstrate compliance with the public
participation requirements of a, above.
This permit requirement ensures notification and opportunity for public involvement in those
elements of the permittee’s stormwater program, and ensures transparent development, updating
and implementation of the permittee’s stormwater program.
Since these requirements have been applicable to all Tier A and Tier B municipalities, no additional
time is necessary for new Tier A permittees to come into compliance, and therefore compliance
with these requirements is due on EDPA for all existing and new Tier A permittees.
2. Municipal Stormwater Webpage
This permit renewal contains a new requirement for permittees to develop and maintain a dedicated
stormwater webpage on their municipal website (see example stormwater webpage at
www.nj.gov/dep/dwq/msrp_outreach_material.htm
). Previously, stormwater related materials
were required to be posted anywhere on the municipality’s website. This requirement will create
greater accessibility for the public by consolidating these materials on a dedicated stormwater page
on the municipality’s website, rather than simply anywhere on their site. The first eleven
28
documents listed below were required to be posted on the Tier A permittees’ websites as per the
2018 Tier A permit:
1) SPPP (excluding inspection logs and other recordkeeping documents);
2) Municipal Stormwater Management Plan (MSWMP);
3) Stormwater Control Ordinance (SCO);
4) Pet Waste Ordinance;
5) Wildlife Feeding Ordinance;
6) Litter Control Ordinance;
7) Improper Disposal of Waste Ordinance;
8) Containerized Yard Waste/Yard Waste Collection Program Ordinances;
9) Private Storm Drain Inlet Retrofitting Ordinance;
10) Illicit Connection Ordinance;
11) MS4 Outfall Pipe Map;
12) Tree Removal/Replacement Ordinance (due on or before EDPA + 12 months as per Part IV.F);
13) Privately-Owned Salt Storage Ordinance (due on or before EDPA + 12 months as per Part
IV.F);
14) MS4 Infrastructure Map (due on or before EDPA + 36 months as per Part IV.G); and
15) Watershed Improvement Plan (due beginning on or before EDPA+36 months, as per Part
IV.H).
The Department will provide an easy-to-fill HTML stormwater webpage template on or before the
issuance of the final permit for municipal webpage administrators to use. and designated contacts,
as noted on the Department’s example templates, to provide 1-on-1 assistance if needed. A
webpage template has already been provided for the 2018 permit, which several towns are currently
using (see https://www.nj.gov/dep/dwq/msrp_outreach_material.htm
).
Existing Tier A permittees will have 3 months to develop this dedicated stormwater webpage with
links to the above referenced documents, with the exception of the Tree Ordinance and Salt Storage
Ordinance, which are not required to be posted until EDPA + 12 months; or the MS4 Infrastructure
Map, which is not required to be posted until EDPA + 36 months.
New Tier A permittees will have EDPA + 12 months to develop this dedicated stormwater webpage
with links to the above referenced documents, with the exception of the MS4 Infrastructure Map,
which is not required to be posted until EDPA + 36 months. Please also see Section F.1 of this fact
sheet below for information concerning the compliance dates for development of the ordinances
listed above.
Existing and New Tier A permittees note that the dates for posting materials related to the
Watershed Improvement Plan are noted in Part IV.H of the permit, and Section 7.H of this Fact
Sheet, and begin on EDPA + 36 months.
C. Minimum Standards for Local Public Education and Outreach (Part IV.C)
The 2018 Tier A and Tier B permits changed the name of this section from “Local Public Education
to “Minimum Standards for Local Public Education and Outreach.” This retained the 2009 name but
expanded it to be more reflective of one of the six Federal Minimum Control Measures namely “Public
Education and Outreach,” which is codified at CFR 122.34(b)(1) (see
www.epa.gov/npdes/stormwater-
discharges). The first component of the Local Public Education and Outreach requirement in this permit
29
renewal continues the public education program as well as a point system as detailed in the Attachment
entitled, “Points System for Public Education and Outreach Activities,” previously included as
Attachment B, is now included as Attachment A.
This renewal permit retains the requirement in accordance with N.J.A.C. 7:14A-25.6(b)4 to achieve a
total of 12 points from three of the five categories for both Tier A and Tier B permittees but removes
the possibility of earning points for having a dedicated stormwater webpage, which is now a permit
requirement under Part IV.B.2. This renewal permit enhances the social media options available for
points under the “General Public Outreach” category, allowing for one point for each social media
platform used, for a maximum of three points. There is now a limit on the number of newspaper ads
and radio/television ads that can be used; one point maximum for newspapers and two points maximum
for radio/television. One of the “Mailing or e-Mailing Campaign” activities in Category 2 has been
renamed to “Private Stormwater Facilities Education,” making it more connected to the description of
the activity and it no longer has the same name as another activity. The remaining “Mailing or e-
mailing Campaign category has been given a maximum of two points allowed.
Please note that former Tier B permittees who become new Tier A permittees under this permit renewal
can no longer earn points for Stormwater Management Design Review Training and Municipal Board
and Governing Body Member Related Training, as those training activities are permit requirements of
this renewal at Part IV.F.7-9, and new Tier A permittees will no longer be able to receive points for
those activities.
Additionally, this renewal permit, consistent with the 2018 Tier A permit, allows the option of earning
points for Ordinance Education to residents and businesses in the municipality. The 2018 Tier B permit
did not have any permit conditions for required ordinance education, so this will be a new way of
earning points for new Tier A permittees.
The second component of this section in the 2018 Tier A, and Tier B permit, concerned the labeling,
maintenance, and replacement of municipally owned or operated storm drain inlets with a message such
as “No dumping, drains to river.” However, the labeling requirement has been moved to Part IV.F.2.iii
of this renewal permit under the “Community-wide Measures” section. All storm drains that do not
have permanent wording cast into them are required to be labeled. This label serves to educate the
public that storm drains shall not be treated as trash receptacles and to convey the message that the
storm drain inlet drains to a waterbody. This labeling applies to all storm drain inlets along sidewalks
that are adjacent to municipal streets, as well as to storm drain inlets within plazas, parking areas or
maintenance yards that are operated by the municipality.
Since these requirements were included in both the 2018 Tier A and B permits, no additional time is
necessary for new Tier A permittees to come into compliance. Therefore, compliance with these
requirements is due on EDPA for all new and existing Tier A permittees.
D. Minimum Standards for Construction Site Stormwater Runoff (Part IV.D)
Stormwater runoff from construction sites can cause significant harm to New Jersey’s rivers, lakes, and
coastal waters if not managed properly. To address these impacts, it is necessary to control soil erosion
and sedimentation during land disturbance, as well as minimize stormwater contamination from other
construction related activities. Managing construction site stormwater runoff is one of the six Federal
Minimum Control Measures, codified at CFR 122.34(b)(4). Any NJPDES permit issued for small
MS4s shall recognize that under N.J.A.C. 7:14A-25.6(b)2, the Department is responsible for
implementing the SBR for construction site stormwater runoff control.
30
The Department satisfies this Minimum Control Measure under a separate Construction Activity
Stormwater General Permit (NJPDES Permit No. NJ0088323). The Construction Activity Stormwater
General Permit (5G3) controls stormwater discharges to surface water from certain construction
activities, including clearing, grading, and excavation. Generally, this includes construction activity
that disturbs at least one acre, or disturbs less than one acre but is part of a larger common plan of
development or sale that ultimately disturbs more than one acre.
The Construction Activity Stormwater General Permit is administered by the Department’s Bureau of
NJPDES Stormwater Permitting and Water Quality Management in coordination with the New Jersey
Department of Agriculture and the State Soil Conservation Committee through its 14 Soil Conservation
Districts located throughout the State (see www.nj.gov/agriculture/divisions/anr/nrc/njdep.html
). The
result of this effort is a program that emphasizes implementation at the district level and maximum
utilization of existing requirements and resources.
Construction activity that may result in stormwater discharges authorized by the Construction Activity
Stormwater General Permit shall be executed only in accordance with a specific Stormwater Pollution
Prevention Plan (SPPP) required by that general permit and is subject to routine inspections identifying
the effectiveness of the SPPP. This SPPP is specific to construction activity under the 5G3 permit and
not to be confused with the municipality’s MS4 SPPP. As a result, and as retained from the 2018 Tier
A permit, the Tier A permittee is not required to specifically address construction site stormwater runoff
control in its MS4 SPPP since it is already regulated in a separate permit.
As a result, and as retained from the 2018 Tier A permit, the Tier A permittee is not required to
specifically address construction site stormwater runoff control in its MS4 SPPP since it is already
regulated in a separate permit. A similar permit condition was included in Part II.C.3.b of the 2018 Tier
B permit under ‘Discharges Not Authorized Under the Tier B MS4 NJPDES Permit’ which stated that,
Any municipality that operates a construction site with such a discharge shall submit a separate RFA
under NJPDES Permit No. NJ0088323 (General Stormwater Permit Construction Activity), or an
application for an individual permit for that discharge. The Construction Activity Stormwater General
Permit (NJ0088323) and associated guidance is posted at www.nj.gov/dep/dwq/5g3.htm
.
Since these requirements were included in both the 2018 Tier A and B permits, no additional time is
necessary for new Tier A permittees to come into compliance, and therefore compliance with these
requirements is due on EDPA for all existing and new Tier A permittees.
E. Minimum Standards for Post Construction Stormwater Management in New Development and
Redevelopment (Part IV.E)
1. General
This renewal permit requires the permittee to implement and enforce a post construction stormwater
management program to address Post Construction Stormwater Management in New Development
and Redevelopment and to ensure compliance with the Stormwater Management rules at N.J.A.C.
7:8 et seq. Post Construction Stormwater Management in New Development and Redevelopment
are components of the minimum control measures at 40 CFR. 122.34(b)(5). The regulatory process
to ensure that such development is both properly designed and thereafter maintained lies largely in
the Stormwater Management rules (N.J.A.C. 7:8) and is complimented by and, in part, implemented
through the NJPDES Stormwater Rules at N.J.A.C. 7:14A-25.6(b)3.
The municipality’s post construction stormwater management program shall require compliance
with the applicable design, performance, and maintenance standards established under the
31
Stormwater Management rules, N.J.A.C. 7:8 et seq. In general, the Stormwater Management rules
at N.J.A.C. 7:8 et. seq. include the following:
Contain requirements for municipal stormwater management plans (MSWMPs) and
stormwater control ordinances (SCOs);
Provide information for the adoption and implementation of MSWMPs and regional
stormwater management plans; and
Establish design and performance standards for stormwater management measures and
establish safety standards for stormwater management basins.
The Stormwater Management rules at N.J.A.C. 7:8 et seq. establish the stormwater management
design and performance standards for new development and redevelopment and require applicants
to design their projects to minimize the adverse impact of stormwater runoff on water quality and
water quantity and loss of groundwater recharge in receiving water bodies. Pursuant to amendments
to those rules adopted in March of 2020, applicants must utilize green infrastructure to achieve
those goals. This permit requires municipalities to implement these rules, or a more stringent
standard, at the local level.
The design and performance components of the Stormwater Management rules are implemented
by the Department through the review of permits issued by the Watershed and Land Management
Program (Flood Hazard, Freshwater Wetlands, Coastal Area Facility Review Act (CAFRA), and
Waterfront Development) and by local authorities through the Municipal Land Use Law (N.J.S.A.
40:55D-1 et seq.), the Residential Site Improvement Standards (RSIS, N.J.A.C. 5:21-7) and local
ordinances. The RSIS are applicable to any residential application that goes before a local board.
Through the RSIS, the Stormwater Management rules become applicable whenever a project meets
or exceeds the definition of major development. (See also
www.nj.gov/dep/stormwater/sw_rule_faqs.htm
).
The post construction stormwater management program established by the permittee shall address
stormwater runoff from “major development” as defined in the Stormwater Management rules at
N.J.A.C. 7:8 et seq. unless any additional development is defined as “major development” by the
permittee’s SCO, which applies to non-residential developments and residential developments that
are not subject to the RSIS. The post construction stormwater management program established by
the permittee shall require compliance with the applicable design and performance standards
established under N.J.A.C. 7:8 et seq., and the permittee’s SCO if it contains more stringent
requirements, for major development.
The permittee shall review and analyze development plans for compliance with N.J.A.C. 7:8 et seq.
and the permittee’s SCO or Residential Site Improvement Standards (RSIS) as applicable, even if
a permit is required by the Department for the same or similar activity (e.g., a Flood Hazard Area
permit). Additionally, the post construction stormwater management program shall ensure that any
residential development and redevelopment projects that are subject to the RSIS for stormwater
management (N.J.A.C. 5:21-7) include any exception, waiver, or special area standard that was
approved under N.J.A.C. 5:21. The Stormwater Management rules (N.J.A.C. 7:8) and the RSIS for
stormwater management (N.J.A.C. 5:21-7), independently and as implemented in this permit, apply
to all areas of the Tier A Municipality.
This permit condition, common to both 2018 Tier A and Tier B permits, is retained largely
unchanged from the 2018 permits, with the exception that the Stormwater Management Design
32
Review (SWMDR) course was only an optional condition for Tier B permittees where they were
welcome to attend and could accrue certain Public Education points if they did attend. This is
further explained below in Section 7.8 of this fact sheet.
One enhancement to this permit renewal is a clarification that compliance with N.J.A.C. 7:8 et seq.
requires the permittee’s review engineer be independent from the design engineer and shall not
have been involved in the design of the development plans. This permit renewal retains the
requirement from the 2018 Tier A permit that the design review engineer shall have completed the
Department’s SWMDR Course within the last five years.
This permit renewal also removes Attachment D, the Major Development Stormwater Summary,
which required detailed information for each structural and nonstructural stormwater management
measure and replaces it with a requirement to include all major development projects approved
each year on the Major Development Project List. A revised version of this attachment, the Major
Development Project List, will now be required to be submitted to the Department annually with
the MSRP Annual Report as part of the Supplemental Questionnaire, which is required to be
uploaded via the RSP.
Since these requirements were included in both the 2018 Tier A and B permits, and the Major
Development Project List is required to be completed for the calendar year beginning on the EDPA
and submitted by the following May 1, no additional time is necessary for new Tier A permittees
to come into compliance, and therefore compliance with these requirements is due on EDPA for
all existing and new Tier A permittees.
2. Municipal Stormwater Management Plan
The renewal permit retains the requirement from the 2018 Tier A and B permit for the permittee to
adopt, amend, and implement a written Municipal Stormwater Management Plan (MSWMP),
pursuant to N.J.A.C. 7:8-4 et seq. to describe the framework of the permittee’s strategy, structure,
and process for addressing stormwater runoff from new development and redevelopment in its post
construction stormwater management program. The MSWMP is a component of the municipality’s
master plan and the elements of an MSWMP are listed in N.J.A.C. 7:8 et seq.
The permittee shall conduct a reexamination of its MSWMP as part of the reexamination of its
municipal master plan in accordance with N.J.A.C. 7:8-4.3(c),4.3(d), and N.J.S.A. 40:55D-89, at
least every 10 years, or more often as necessary to reflect changes related to the permittee’s
stormwater management program (e.g., if required due to amendments to the Stormwater
Management rules at N.J.A.C. 7:8 et seq.).
The permittee shall submit the adopted MSWMP to the county review agency for review and
approval pursuant to the requirements at N.J.A.C. 7:8-4.4 (this includes MSWMP reexaminations
without change). Within thirty (30) days of the effective date of the plan this permit requires the
permittee to electronically submit the county approved MSWMP and any amendments to the
Department and post the county approved MSWMP and any amendments on the permittee’s
dedicated stormwater webpage.
This requirement, common to both 2018 Tier A and Tier B permits, also remains largely unchanged
from the 2018 Tier A and Tier B permits, but with minor enhancements. These enhancements are
that the permittee must submit the MSWMP reexaminations to the county review agencies, as noted
above, for their review and approval, and that the permittee must include on the MSWMP the date
of the last reexamination/revision approved by the county review agency.
33
Since these requirements were included in both the 2018 Tier A and B permits, no additional time
is necessary for new Tier A permittees to come into compliance, and therefore compliance with
these requirements is due on EDPA for all existing and new Tier A permittees.
3. Stormwater Control Ordinances
In order to implement the post construction stormwater management program, the permittee shall
adopt, amend, implement, and enforce a stormwater control ordinance (SCO) in accordance with
N.J.A.C. 7:8 and N.J.A.C 14A-25.6(b)3.iv(3). The SCO shall include, at a minimum, the following
elements:
Control aspects of residential development and redevelopment projects that are not pre-empted
by the RSIS;
Control stormwater from non-residential development and redevelopment projects, in
accordance with the requirements at N.J.A.C. 7:8; and
Set forth special area standards approved by the Site Improvement Advisory Board for
residential development or redevelopment projects under N.J.A.C. 5:21-3.5.
A model SCO consistent with the requirements of the Stormwater Management rules, as well as a
model SCO for towns that are subject to the regulatory requirements of the Pinelands Commission,
are posted at https://www.nj.gov/dep/dwq/example_ordinance.htm
. These model SCOs are
provided as a courtesy and are not required to be adopted verbatim by the permittee as long as the
applicable permit and regulatory requirements are met. For example, the permittee could adopt
more stringent stormwater management requirements in its SCO pursuant to N.J.A.C. 7:8-1.5(a).
Where the Pinelands Commission regulatory requirements at N.J.A.C. 7:50- 3 are applicable, the
municipal SCO (and any amendments) shall be certified by the Pinelands Commission. See
www.nj.gov/dep/stormwater/pinelands.htm or contact the Pinelands Commission for a model
Pinelands’ SCO.
The municipal SCO was originally required in the 2004 Tier A and Tier B permit, however, on
March 2, 2020, amendments to the Stormwater Management rules at N.J.A.C. 7:8 et seq. were
adopted necessitating required changes to each municipality’s SCO. In order to require that a
municipality keep its ordinances up-to-date (with this permit or with any legislative or regulatory
changes that occur outside of this permit), and consistent with N.J.A.C. 7:8-4.3(b), this permit
continues to require (Part IV.A.1.b) the permittee to modify and update its stormwater program
within one year of any notification by the Department that such a change is necessary. On March
2, 2020, a letter was sent to all municipal MS4 permittees providing written notification that their
stormwater programs, including their SCOs, must be revised within 12 months of the notice to
conform with the amended Stormwater Management rules. More specifically, their municipal SCO
was required to be revised to conform with these amendments by March 3, 2021.
Since these requirements were included in both the 2018 Tier A and B permits, no additional time
is necessary for new Tier A permittees to come into compliance, and therefore compliance with
these requirements is due on EDPA for all existing and new Tier A permittees.
34
4. Mitigation Plans
This permit renewal retains the permit condition from the 2018 Tier A and Tier B permits that states
that a municipality can grant a variance from the design and performance standards for stormwater
management measures, if the conditions at N.J.A.C. 7:8-4.6(a)1 and (a)2 are met, provided the
permittee has a mitigation plan included in an approved MSWMP, which meets the following
requirements:
A mitigation plan identifies what measures are necessary, potential mitigation projects, and/or
criteria to evaluate mitigation projects that can then be used to offset the deficit created by a
municipality granting a variance from an approved MSWMP and SCO. The mitigation plan
must comply with the Stormwater Management rules at N.J.A.C. 7:8-4.6. N.J.A.C. 7:8-
4.2(c)11. Additional information regarding mitigation plans can be found in Chapter 3 of the
NJ Stormwater BMP Manual at https://www.njstormwater.org
;
The mitigation project is in accordance with the requirements provided in N.J.A.C. 7:8-
4.6(a)3.i through (a)3.x; and
The permittee submits, within (30) days after approving a variance, a written report to the to
the county review agency and to the Department via email (
dwq-bnpc-
stormwatermanag[email protected]) describing the variance and the required mitigation. See
N.J.A.C. 7:8-4.6(b).
Since these requirements were included in both the 2018 Tier A and B permits, no additional time
is necessary for new Tier A permittees to come into compliance, and therefore compliance with
these requirements is due on EDPA for all existing and new Tier A permittees.
F. Minimum Standards for Pollution Prevention / Good Housekeeping for Municipal Operators
(Part IV.F)
Since there are many requirements within this section of the renewal permit, the Department is
providing F 1 as a tabular outline of the heading changes and re-ordering of topics from the 2018 Tier
A permit to this renewal permit under the Minimum Standards for Pollution Prevention/Good
Housekeeping for Municipal Operators section to assist with readability. The specific discussions
regarding the requirements, and the changes thereto, are included in the order they appear in the renewal

General Overview
The 2009 Tier A permit contained the following four sections:
Improper Disposal of Waste (N.J.A.C. 7:14A-25.6(b)5);
Solids and Floatable Controls (N.J.A.C. 7:14A-25.6(b)6);
Maintenance Yard Operations (N.J.A.C. 7:14A-25.6(b)7); and
Employee Training (N.J.A.C. 7:14A-25.6(b)8).
The 2018 Tier A permit merged those sections into a newly named section entitled “Pollution
Prevention/Good Housekeeping for Municipal Operators.” This name is derived from one of the
six Federal Minimum Control Measures (See CFR 122.34(b)(6)) and clarifies that Tier A
municipalities can utilize Federal guidance for this permit requirement. See the “National Menu of
Best Management Practices (BMPs) for Stormwater” at
https://www.epa.gov/npdes/stormwater-
discharges-municipal-sources.
The 2018 Tier A permit included the four previous sections from the 2009 Tier A permit, with the
addition of:
Community-wide Ordinances; and
Community-wide Measures.
The 2018 Tier A and Tier B permits had the same requirement for Storm Drain Inlet Labeling,
which was included under the Local Public Education and Outreach section of both permits. In
this permit renewal, Storm Drain Inlet Labeling has been moved to the Community-wide Measures
section.
This permit renewal retains the Minimum Standards for Pollution Prevention / Good
Housekeeping for Municipal Operators” heading from the 2018 Tier A permit and includes four of
the six of the sections noted above from the 2018 Tier A permit, excluding Improper Disposal of
Waste and Solids and Floatable Controls. The requirements from these 2 sections have been
retained in this permit but have been moved under different sections of this permit renewal;
permittees are required to have an Improper Disposal of Waste Ordinance per Part IV.F.1.iv., and
solids and floatables are controlled through the various BMPs described in the Community-wide
Measures section detailed in Part.IV.F.2.
The following sections have been added under the “Minimum Standards for Pollution Prevention /
Good Housekeeping for Municipal Operators” heading in this permit renewal:
Inspection and Maintenance of Permittee Owned or Operated Stormwater Facilities; and
Inspection and Maintenance of Stormwater Facilities not Owned or Operated by the Permittee.
These requirements were previously included under Minimum Standards for Stormwater Facilities
37
Maintenance in the Other Control Measures section of the 2018 Tier A permit and in the Minimum
Standards for Post Construction Stormwater Management in New Development and
Redevelopment section of the 2018 Tier B permit. This permit renewal also adds another new
requirement, the Stormwater Management Rule Amendment Training, under this heading. The
following conditions have also been retained from the 2018 permit but clarified with revisions in
this permit renewal:
Annual Employee Training;
Stormwater Management Design Review (SWMDR) Training; and
Municipal Board and Governing Body Member Related Training.
This permit renewal also includes two new Community-wide Ordinances which are the Tree
Removal/Restoration Ordinance and Privately Owned Salt Storage Ordinance. The permit renewal
also rearranged, added, and clarified the Community-wide Measures section. This section in the
2018 Tier A permit only had three requirements, Street Sweeping, Catch Basin and Inlet Inspection
and Cleaning, and Storm Drain Inlet Retrofitting. The 2018 Tier B permit indirectly required catch
basin and inlet inspection and cleaning as those activities are necessary to ensure the requirement
to provide adequate long-term cleaning, operation and maintenance of stormwater management
measures was met. The Community-wide Measures section in the draft permit renewal now
contains nine requirements: Triannual Street Sweeping, Annual Street Sweeping, Storm Drain Inlet
Labeling, Storm Drain Inlet Retrofitting, Storm Drain Installation, Herbicide Application
Management, Excess De-icing Material Management, Roadside Vegetative Waste Management,
and Roadside Erosion Control. The street sweeping requirements have been divided into two
sections, Triannual Street Sweeping and Annual Street Sweeping. Catch Basin and Storm Drain
Inlet Inspection and Cleaning has moved to Part IV.F.3.i-iv in this draft renewal, which has been
titled “Inspection and Maintenance of Permittee Owned or Operated Stormwater Facilities” and
has been divided into four categories to clarify requirements; Storm Drain Inlet Inspection, Storm
Drain Inlet Cleaning and Maintenance, Catch Basin Inspection, and Catch Basin Cleaning. The
Tier A Storm Drain Inlet Retrofit requirement has also been renamed to the new “Storm Drain Inlet
Retrofitting” requirement. The 2018 Tier B permit had the same requirement as the 2018 Tier A
permit for Storm Drain Inlet Labeling under the Local Public Education and Outreach section in
both permits. In this permit renewal, Storm Drain Inlet Labeling has been moved to the
Community-wide Measures section.
A detailed basis and background, including an explanation of any changes, for each permit
requirement is included below.
1. Community-wide Ordinances (Part IV.B.5.a)
This permit renewal proposes to retain the six Community-wide ordinances (pet waste, wildlife
feeding, litter control, improper disposal of waste, yard waste collection, and private storm drain
inlet retrofitting) from the 2018 Tier A permit, which state:
i. Pet Waste Ordinance: Adopt and enforce an ordinance that requires pet owners or their
keepers to immediately and properly dispose of their pet's solid waste deposited on any
property, public or private, not owned or possessed by that person. Information on the Pet
Waste Ordinance and the benefits of proper disposal of pet solid waste shall be distributed with
pet licenses. See the Tier A Municipal Guidance document
(
www.nj.gov/dep/dwq/tier_a_guidance.htm) for a sample ordinance;
ii. Wildlife Feeding Ordinance: Adopt and enforce an ordinance that prohibits the feeding of
38
any wildlife (e.g., Canada Geese) in any public park or on any other property owned or operated
by the Tier A Municipality. Exclusions include wildlife confined in zoos, parks, or
rehabilitation centers as well the following unconfined animals: (1) wildlife at environmental
education centers; (2) feral cats as part of an approved Trap-Neuter-Release program; and (3)
other kinds of unconfined animals, if any, that the ordinance specifically lists and excludes for
reasons set forth in the ordinance. See the Tier A Municipal Guidance document
(www.nj.gov/dep/dwq/tier_a_guidance.htm
) for a sample ordinance;
iii. Litter Control Ordinance: Adopt and enforce a litter ordinance or enforce the existing State
litter statute at N.J.S.A 13:1E-99.3. See the Tier A Municipal Guidance document
(
www.nj.gov/dep/dwq/tier_a_guidance.htm) for a sample ordinance;
iv. Improper Disposal of Waste Ordinance: Adopt and enforce an ordinance prohibiting the
improper spilling, dumping, or disposal of materials other than stormwater into the MS4 system
excluding those discharges as allowable under Part II.C.2.b. See the Tier A Municipal
Guidance document (
www.nj.gov/dep/dwq/tier_a_guidance.htm) for a sample ordinance;
v. Containerized Yard Waste/Yard Waste Collection Program Ordinances: (1) Adopt and
enforce an ordinance that prohibits placing non-containerized yard wastes (defined as leaves
and/or grass clippings) into the street; or (2) develop and implement a non-containerized yard
waste collection and disposal program that includes adoption and enforcement of an ordinance
that prohibits placing non-containerized yard waste at the curb or along the street within 10 feet
of any storm drain inlet and at any time other than a set yard waste collection schedule. The
frequency of yard waste pickups shall be determined at the discretion of the Tier A Municipality
but shall be part of a set yard waste collection schedule which is noticed to all municipal
residents and businesses. Any area, which the municipality determines to have no yard waste,
will be exempt from the collections. See the Tier A Municipal Guidance document
(
www.nj.gov/dep/dwq/tier_a_guidance.htm) for sample ordinances; and
vi. Private Storm Drain Inlet Retrofitting Ordinance: Adopt and enforce an ordinance
requiring the retrofitting of existing storm drain inlets on private property to meet the standard
in Attachment C (Design Standard for Storm Drain Inlets). Specifically, this ordinance: 1) shall
apply to storm drain inlets, on property not owned or operated by the Tier A Municipality (e.g.,
condominium associations), that are in direct contact (i.e. contiguous) to repaving; repairing
(excluding individual pothole repair); resurfacing (including top coating or chip sealing with
asphalt emulsion or a thin base of hot bitumen); and reconstruction or alteration of facilities;
and 2) shall not apply to a residential lot with one single family house. For a sample ordinance
see
www.nj.gov/dep/dwq/tier_a.htm.
The permittee, via these ordinances and consistent with N.J.A.C. 7:14A-25.6(b)5.iii, must effectively
prohibit improper disposal of waste into the permittee’s MS4 and implement appropriate enforcement
procedures and actions. Consistent with the 2004, 2009, and 2018 Tier A permits, the Department
continues to provide model ordinances posted at www.nj.gov/dep/dwq/tier_a.htm.
These models of
the eight Community-wide Ordinances, including the newly required ordinances discussed below, have
been developed as a courtesy, but municipal ordinances are not required to be adopted verbatim as long
as applicable permit and regulatory requirements are met.
The content of the permit requirements regarding ordinances, as well as the suggested model ordinances
for pet waste, litter, improper disposal of waste, wildlife feeding, yard waste collection, and private
storm drain inlet retrofitting, are consistent with the 2018 Tier A permit. Because this has been a
longstanding Tier A permit requirement, existing Tier A Municipalities should already be in
39
compliance and not have to readopt or amend those ordinances for the purposes of this permit renewal.
This does not relieve a municipality from the requirement to keep all ordinances up to date with any
legislative or regulatory changes that occur outside of this permit.
In addition to those ordinance requirements retained, the Department has included 2 additional
ordinances:
vii. Privately-Owned Salt Storage Ordinance: This renewal requires permittees to adopt and
enforce an ordinance requiring salt and other solid (granular) de-icing material to be covered
when not in use to prevent exposure to rain, snow, or stormwater run-on. The use of anti-icing
agents is critical to the public safety and economy of the state during winter precipitation
events. Their use is widespread, both publicly and privately, despite the environmental impacts
that de-icing agents can cause. When uncovered, pollutants from these piles are transported by
winds, waters, human activities, etc. into the nearest storm drain inlet. Road salt being
deposited into the receiving surface waters has become a nationwide problem, as the increase
in chloride levels can be toxic to aquatic life and can contaminate surface and ground water
drinking water supplies. While these discharges of salt laden runoff could have been enforced
by the permittee through the improper disposal of waste ordinance that is already required,
discharges from uncovered piles were witnessed in many locations within municipalities during
our MS4 stormwater compliance audits and enforcement inspections, which were reported to
the Department via complaints received from the general public. The requirement to develop
and implement this ordinance is therefore being added to this permit renewal so that the
permittees municipal authority in this regard is very clear.
This ordinance is intended to reduce the detrimental effects of salt laden stormwater runoff on
our surface and ground waters due to unnecessary runoff from improperly stored, private
stockpiles by further empowering permittees to hold privately owned salt stockpiles (e.g., at
commercial or industrial locations, such as shopping centers or industrial parks) to similar
management requirements as the municipality and industrial permittees. Similar to the
ordinance requirements in the prior Tier A Permit, the Department will provide a sample salt
storage ordinance at https://nj.gov/dep/dwq/tier_a.htm
.
viii. Tree Removal/Restoration Ordinance: This new permit requirement to adopt and enforce an
ordinance to control tree removal and the replacement of any trees that are removed is derived
from stakeholder involvement during 2019 regarding improvements to the Stormwater
Management program and rule language, and the ongoing need for enhanced stormwater
management strategies. Trees play a critical, often overlooked, role in the water cycle and can
mitigate stormwater runoff issues. This ordinance is intended to ensure that permittees are
considering these undervalued assets in their water quality management efforts. This permit
renewal requires permittees to adopt and enforce an ordinance to control tree removal and
replacement to reduce stormwater runoff and pollutants, and to promote infiltration of
rainwater into the soil. The minimum standards would be provided in a model ordinance to be
developed by the Department for each municipality for consideration of their own tree
ordinance.
The Department recognizes that permittees may be concerned that adopting and enforcing these two
additional stormwater ordinances will expand the burden of enforcement activities and incur more costs
and municipal resources. However, it should be noted that there is no requirement for permittees to
schedule inspections for compliance of these ordinances, and that the enforcement of these ordinances
may be incidental to other municipal activities, by any municipal employees, including those with
enforcement responsibilities. As such, the permittee should not incur any additional significant costs
40
due to enforcement of these activities. The permittee may opt to require fees for permits to remove any
trees that meet the ordinance specifications and/or instruct police officers to scrutinize any private salt
piles they come across during routine patrols. Permittees may choose to include penalty language in
their ordinance(s) for violators to cover any costs associated with any enforcement actions, but are not
required to.
The requirement to adopt the ordinances listed in i through vi above was included in the previous Tier
A permits, therefore. no additional time is necessary for existing Tier A permittees to come into
compliance, and compliance with those requirements is due on EDPA. However, existing Tier A
permittees will have 12 months from EDPA to adopt the two new ordinances for Privately Owned Salt
Storage and Tree Removal/Restoration.
New Tier A permittees will have 12 months from EDPA to adopt all Community-wide Ordinances.
ix. Optional Privately-Owned Refuse Container/Dumpster Ordinance: The 2009 permit
required the adoption and enforcement of an ordinance for dumpsters and other refuse
containers that are outdoors or exposed to stormwater to be covered at all times. However, this
requirement was not carried forward as a permit requirement in this draft permit based on a
December 21, 2011 decision by the Council on Local Mandates in response to a complaint filed
by Roxbury Township. As a result, the Department has moved the Refuse Container / Dumpster
Ordinance from the 2009 permit from a permit requirement to an Optional Measure.
Specifically, Tier A Municipalities have the option of adopting and enforcing an ordinance
requiring dumpsters and other refuse containers that are outdoors or exposed to stormwater to
be covered at all times. According to Annual Reports submitted by Tier A Municipalities for
the 2015 reporting year, 434 of New Jersey’s 457 year 2009 Tier A permittees adopted a Refuse
Container / Dumpster Ordinance. Municipalities that are not maintaining this ordinance must,
as required at Part IV.B.5.b.ii (Catch Basin and Storm Drain Inlet Inspection and Cleaning),
clean any municipally owned or operated storm drain inlet or catch basin more frequently to
eliminate recurring problems and restore proper function due, in this case, to uncovered refuse
containers that are outdoors or exposed to stormwater. The purpose of the ordinance is to
prohibit the spilling, dumping, leaking, or otherwise discharge of liquids, semi-liquids or solids
from these containers, thus reducing the need to frequently clean those municipal storm drains
or catch basins. This ordinance is not intended for: litter receptacles; individual homeowner
trash and recycling containers; containers that hold large bulky items (e.g., furniture, bound
carpet, and padding); permitted temporary demolition containers; and refuse containers at
industrial facilities authorized to discharge stormwater under a valid NJPDES permit. For a
model ordinance, see
www.nj.gov/dep/dwq/tier_a.htm.
2. Community-wide Measures (Part IV.F.2)
As described in Table F-1 , this permit renewal contains nine requirements under the heading of
“Community-wide Measures.” Most of these community-wide pollution prevention and good
housekeeping measures are required to control solid and floatable materials. Herbicide Application
Management and Excess De-icing Material Management are required to protect water quality from
direct discharges from inappropriate roadside herbicide application and saline discharges from
excess piles of road salt that would have otherwise remained on the road until they completely
dissolved into the stormwater runoff.
The 2018 Tier A permit contained three sections under this heading:
Street Sweeping;
Catch Basin and Storm Drain Inlet Inspection and Cleaning
41
o (this requirement has been moved under ‘Inspection and Maintenance of Permittee Owned
or Operated Stormwater Facilitiesat Part IV.F.3.i-iv of the permit and is described below)
Tier A Municipality Storm Drain Inlet Retrofit.
This renewal permit contains nine sections under this heading:
Triannual Street Sweeping;
Annual Street Sweeping (the street sweeping requirements have been divided into these two
sections, Triannual Street Sweeping and Annual Street Sweeping)
Storm Drain Inlet Labeling;
Storm Drain Inlet Retrofitting;
Storm Drain Installation;
Herbicide Application Management;
Excess De-icing Material Management;
Roadside Vegetative Waste Management; and
Roadside Erosion Control.
i. Street Sweeping:
Street Sweeping has been a permit requirement since the 2004 Tier A Permit. The sweeping
requirement proposed in this permit renewal would be broadened to apply to all permittee
owned roads, as opposed to only some permittee owned roads as per the 2018 Tier A permit.
However, the frequency requirement would be reduced to either one of two different
frequencies: triannually or annually dependent on whether the segments of the roads have storm
drains that discharge to surface waters, or not, respectively. The Department proposes that these
revised street sweeping requirements constitute an overall increase in the road miles that will
be swept on an annual basis and consequently, a reduction in solid and floatable materials
discharged to surface waters. This requirement is being enhanced to meet the
reduction/elimination of solid and floatable materials requirement in the Federal MS4 rule at
40 CFR 122.34(b)(6)(ii) and N.J.A.C. 7:14A-25.6(b)6. The Department made similar changes
to the Public Complex and Highway Agency MS4 permits for 2019 and 2020, respectively.
This change is being made because the number of municipal road miles required to be swept
monthly under the existing permit is limited, as those roads had to be in a predominantly
commercial area, have storm drain inlets, curbs, and a posted speed limit of 35 MPH or less.
The majority of the roads that meet the proposed sweeping conditions are county or New Jersey
Department of Transportation roads, and, thus, are not the responsibility of the municipality.
The Department acknowledges that many permittees already implement more frequent and
widespread street sweeping than required by the 2018 Tier A permit.
Since the sweeping frequency is proposed to be reduced concurrent with an increase in the area
to be swept, additional costs should be minimal in most towns. Permittees may further reduce
their financial burden under this requirement by sharing services with other entities. This may
include other MS4 permittees, such as municipalities and Highway Agencies. Any increase in
sweeping costs should be offset by the reduced costs associated with reduced catch basin
cleaning and vacuuming. These revised sweeping requirements will also reduce flooding due
to clogged storm drain inlets, and thus be more protective of public health and safety.
Specifically, the 2018 Tier A permit required permittees to:
“Sweep, at a minimum of once per month (weather and street surface conditions permitting),
all streets (including roads or highways) that meet all of the following criteria: (1) the street is
42
owned or operated by the municipality; (2) the street is curbed and has storm drains; (3) the
street has a posted speed limit of 35 miles per hour or less; (4) the street is not an entrance or
exit ramp; and (5) the street is in a predominantly commercial area.”
In this permit renewal, street sweeping for the permittee has been split into Triannual Street
Sweeping and Annual Street Sweeping. For Triannual Sweeping:
“The permittee shall sweep, at a minimum of once every four months, or more frequently as
necessary to eliminate recurring problems, all segments of roads that are owned or operated by
the permittee and have storm drain inlets that discharge to surface water. Existing Permittees
shall continue with monthly street sweeping until the new triannual sweeping program is
implemented on or before EDPA + 12 months. New Permittees shall begin this sweeping
program on or before EDPA + 12 months.”
For the Annual Street Sweeping requirement:
“The permittee shall sweep, at a minimum of once per year, or more frequently as necessary to
eliminate recurring problems, all segments of roads that are owned or operated by the permittee
that do not have storm drain inlets that discharge to surface water. Existing Permittees shall
continue with monthly street sweeping until the new annual sweeping program is implemented
on or before EDPA + 12 months. New Permittees shall begin this sweeping program on or
before EDPA + 12 months.”
ii. Storm Drain Inlet Labeling:
Storm drain inlet labeling in the 2018 Tier A and Tier B permits was located under the
“Minimum Standards for Local Public Education and Outreach” heading. This has moved to
the “Community-wide Measures” section in this permit renewal” and states:
“The permittee shall label all permittee owned or operated storm drain inlets that do not have
permanent wording cast into the structure of the inlet.”
“This applies to inlets that are located along sidewalks that are adjacent to municipal streets,
and within plazas, parking areas, maintenance yards or other ancillary activities that are
operated by the permittee.”
Since these requirements were included in both the 2018 Tier A and B permits, no additional
time is necessary for new Tier A permittees to come into compliance, and therefore compliance
with these requirements is due on EDPA for all existing and new Tier A permittees.
iii. Storm Drain Inlet Retrofitting:
The Tier A Municipality Storm Drain Inlet Retrofit condition from the 2018 Tier A permit has
been renamed to Storm Drain Inlet Retrofittingin this renewal permit. In the 2018 Tier A
and Tier B permit, retrofitting of municipally owned or operated storm drain inlets was only
required when:
“(1) in direct contact with any repaving, repairing (excluding any pothole repair), or
resurfacing (including top coating or chip sealing with asphalt emulsion or a thin base of
hot bitumen); or (2) in direct contact with any reconstruction or alteration of facilities.
Storm drain inlet retrofits shall meet the standard in Attachment C (Design Standards for
Storm Drain Inlets).”
43
In the draft permit renewal, the requirement has changed to state:
“The permittee shall comply with the standards set forth in Attachment B (Design
Standards for Storm Drain Inlets) of this permit to control passage of solid and floatable
materials through storm drain inlets installed by the permittee. The permittee shall retrofit
all permittee owned or operated storm drain inlets with the standards set forth in
Attachment B on or before EDPA + 59 months.”
As noted above, the due date for existing and new Tier A permittees to retrofit all remaining
permittee owned or operated storm drain inlets with the standards set forth in Attachment B is
EDPA + 59 months. Tier A and Tier B municipalities have been required to retrofit any storm
drain inlets that come in contact with repaving since the first iteration of the MS4 general
permits in 2004. Storm drain inlets must be replaced or retrofitted to restrict the passage of
solids/floatables, and in doing so, reduces the municipality’s costs of needing to employ the
use of a vacuum truck to clean the catch basin below the inlet.
The Department asserts that it is appropriate to set a deadline of EDPA + 59 months for all
storm drain inlets to be retrofit since permittees have been required to retrofit them for repaving
and utility projects for over 20 years. We anticipate that the number of inlets that municipalities
will need to retrofit (outside of those that are in non-compliance of the existing requirement
during repaving, etc.) has been reduced significantly since 2004. Retrofitting can be
accomplished with relatively insignificant costs by bolting a grate over the large curb opening,
which would be much less costly than replacing the entire inlet structure. Not all municipalities
have fully complied with this requirement during repaving or have left a buffer of pavement
around the old inlet as to avoid triggering the need to retrofit during a repaving project. Some
retrofits have not occurred due to a lack of repaving/maintenance, even though the lifespan of
most asphalt roads is 20 years or less.
Since the requirement to retrofit in accordance with Attachment B (formerly Attachment C))
when repaving, repairing, or resurfacing roads, or during reconstruction or alteration of
facilities, was included in both the 2018 Tier A and B permits, no additional time is necessary
for new Tier A permittees to come into compliance, and therefore compliance with that
requirement is due on EDPA for all existing and new Tier A permittees.
iv. Storm Drain Inlet Installation:
The renewal permit includes a new section not included in the 2018 permits called Storm
Drain Inlet Installation.” This requirement applies to the installation of new storm drain
infrastructure and is not a requirement to begin retrofitting existing storm drains. This
requirement is being added in the renewal permit to reduce the amount of solid and floatable
material being discharged into the receiving waters and to meet the reduction/elimination of
solid and floatable materials requirement in the Federal rule at 40 CFR 122.34(b)(6)(ii). The
requirement in this permit states:
“The permittee shall not install storm drains that do not include a catch basin or other BMP
designed for solids collection.”
Additional costs should be minimal for most permittees as retrofitting of stormwater inlet
BMPs is not required. This requirement will only be triggered when permittees install new
storm drain inlets, and the cost of installing a new inlet with a catch basin should be minimal
relative to the cost of the overall improvement project and are minimal compared to the overall
water quality benefit they produce. Further, the catch basin would only be required when there
44
is no other BMP (such as a stormwater basin or MTD) located between the new inlet and the
outfall.
Existing Tier A permittees and new Tier A permittees shall implement this requirement upon
EDPA.
v. Herbicide Application Management:
Some permittees apply herbicides as part of their municipal services. Management of this
application was addressed in the 2018 Tier A permit under the heading Roadside Vegetation
Managementfound in Attachment E (Best Management Practices for Municipal Maintenance
Yards and Other Ancillary Operations). This provided BMPs for roadside vegetation
management. The name of this requirement is being revised for clarification in this renewal
permit to Herbicide Application Management and it is being moved under the “Community-
wide Measuressection, but the text of the requirement is retained from the 2018 Tier A permit,
and still states:
“The permittee shall restrict the application of herbicides to prevent herbicides from being
washed into the waters of the State and to prevent erosion caused by de-vegetation. At a
minimum, the permittee shall: (1) not apply herbicides on or adjacent to storm drain inlets,
or on steeply sloping ground; (2) only apply herbicides along curb lines and unobstructed
shoulders that contain unwanted vegetation; and (3) only apply herbicides within a 2-foot
radius around structures where overgrowth presents a safety hazard and where it is unsafe
to mow.”
The Department already incorporated this clarification in the 2019 Public Complex MS4 permit
renewal and in the 2020 Highway Agency MS4 permit renewal.
Application of herbicides is an optional practice so this requirement may not be applicable to
every municipality. Since these requirements do not require purchase of equipment and the
program is to essentially ‘not’ spray herbicide in certain areas, compliance with these
requirements is due on EDPA for all existing and new Tier A permittees.
vi. Excess De-Icing Material Management:
The Department has added a new requirement in this renewal permit for Excess De-Icing
Material Management. This requirement is in response to citizen complaints and the
Department’s observations in the field regarding piles of excess road salt that have remained
on or adjacent to the roadways, parking lots, etc. long after storms had passed. This condition
requires permittees cleanup excess de-icing material deposited during spreading operations
(e.g., piles resulting from accidental spillage or when spreading equipment is started or
stopped) on all streets and parking areas owned or operated by the permittee, after a storm
event. This requirement is intended to target unintentionally created salt piles that are formed
from stopping and starting the salt spreaders, or any other means. The permittee will be required
to remove any excess salt piles from these surfaces remaining after 72 hours of the end of the
storm, conditions permitting. This requirement has already been added and implemented in
the 2020 Highway Agency MS4 permit. The renewal permit requirement states:
The permittee shall remove, within 72 hours after the end of the storm event, conditions
permitting, piles of excess salt and de-icing materials that have been deposited during
spreading operations (e.g., piles resulting from accidental spillage or when spreading
equipment is started or stopped) on all streets and parking areas owned or operated by the
permittee. Excess de-icing material removed from streets and parking areas may be
45
returned to storage or properly managed if unsuitable for reuse.”
Since these requirements do not require any additional equipment and should not require a
significant increase in staff time as there should not be a large number of these piles, and the
permittees have 72 hours to address these piles, no additional time should be necessary for new
or existing Tier A permittees to come into compliance, and therefore compliance with these
requirements is due on EDPA for all existing and new Tier A permittees.
vii. Roadside Vegetative Waste Management:
As noted above in Section 7.F.2 of this Fact Sheet, in the 2018 Tier A permit, Roadside
Vegetation Management was listed under Part IV.B.5.c. Municipal Maintenance Yards and
Other Ancillary Operations” under the heading “Minimum Standards for Pollution Prevention
/ Good Housekeeping for Municipal Operators.” However, that requirement addressed the
application of herbicides along roadsides in order to prevent it from being washed by
stormwater into the waters of the State and to prevent erosion caused by de-vegetation. That
condition has been renamed ‘Herbicide Application Management’ and is discussed above.
This renewal permit has added a new requirement entitled, Roadside Vegetative Waste
Managementand it states:
“The permittee shall ensure the proper pickup, handling, storage and disposal of wood
waste and yard trimmings generated by the permittee. Wood waste and yard trimmings
shall be managed to minimize the impact of vegetative maintenance activities on
stormwater discharge quality and shall be prohibited from being blown or deposited into
storm drain inlets and stormwater facilities.”
This requirement is intended to ensure appropriate management of materials generated from
activities such as mowing, tree trimming, and wood chipping along municipal roads or
municipal properties so that these materials are not transported into the MS4, thus increasing
maintenance requirements and resulting costs for the permittees. This requirement is also
intended to eliminate these materials from being transported to and have negative impacts on
the receiving waters. This update has already been incorporated into the 2020 Highway
Agency MS4 permit.
Since these requirements do not require any additional equipment and should not require any
significant increase in staff time to restrict the ability of these materials to be transported via
stormwater, no additional time should be necessary for new or existing Tier A permittees to
come into compliance, and therefore compliance with these requirements is due on EDPA for
all existing and new Tier A permittees.
viii. Roadside Erosion Control:
This renewal permit reincorporates the requirement for Roadside Erosion Control from the
original 2004 Tier A permit. In the 2004 Tier A permit there was a section called Roadside
Erosion Control Maintenance” at Part I.F.7.d. that was implemented to require Tier A
municipalities to develop a roadside erosion control maintenance program. The 2004 permit
stated that the minimum standard for Tier A municipalities shall be to:
Develop a roadside erosion control maintenance program to identify and repair erosion
along streets (including roads or highways) operated by the municipality. Tier A
Municipalities are also required to regularly inspect and maintain the stability of shoulders,
embankments, ditches, and soils along these streets to ensure that they are not eroding and
46
contributing to sedimentation of receiving waters. Repairs shall be made in accordance
with the Standards for Soil Erosion and Sediment Control in New Jersey (N.J.A.C. 2:90-
1).”
This section was removed in the 2009 Tier A permit because, at the time, it was viewed as a
redundancy, since municipalities are required to control erosion under the Standards for Soil
Erosion and Sediment Control in New Jersey (N.J.A.C. 2:90-1). This section was also kept out
of the 2018 permit for the same reason. However, those standards only applied to construction
sites, while this permit requirement will apply to existing roadways. In this permit renewal
permit, this requirement has been reintroduced in response to citizen complaints and
Department inspections and observations of roadside erosion. This condition is also being
restored in the permit to provide additional water quality protection, and as a stormwater
facility maintenance requirement, as roads are considered to be part of the municipalities’
stormwater conveyance systems. New Jersey has approximately 35,600 miles of roads, and
more highways per square mile than any other state. Erosion of or along these streets, highways,
and other roads contributes suspended solids, sediment and other materials to storm sewer
systems and waterways.
Permittees will be required to re-implement the road and roadside erosion control maintenance
program to identify and repair erosion along streets (including roads or highways) operated by
the permittee. Permittees would also be required to regularly inspect and maintain the stability
of shoulders, embankments, ditches, and soils along these streets to ensure that they are not
eroding and contributing to clogging or destabilization of stormwater infrastructure, or
sedimentation of receiving waters.
Sedimentation not only causes an increase of permittee costs for ditch, culvert and catch basin
cleaning to ensure proper operation and maintenance and prevent associated flooding, it is also
the single largest contributor of pollution to our nation’s waters. Sedimentation and the
deposition of material eroded by runoff from roads and roadsides can significantly impact water
quality, and when not maintained, this erosion can also convey a significant amount of
pollutants in the stormwater runoff. Sedimentation can also lead to a decrease in water carrying
and storage capacities of streams and reservoirs, as well as destroy fish and other aquatic
habitats. For example, sedimentation can fill the pores between gravel and cobble stream
bottoms, greatly decreasing the spawning areas for many fish species (including native trout)
and the habitat for macroinvertebrates, which serve as food for many fish species.
The reintroduced Roadside Erosion Controlrequirement has been added under Community-
wide Measuresand states:
“The permittee shall develop a program to detect and repair erosion along the roads owned
or operated by the permittee and to inspect and maintain the stability of shoulders,
embankments, ditches, and soils along these roads to ensure that they are not eroding and
contributing to the sedimentation of receiving waters. Any repairs shall be completed as
soon as practicable, but no later than 90 days from discovery, unless another timeframe is
authorized by the Department, and be made in accordance with the Standards for Soil
Erosion and Sediment Control in New Jersey, N.J.A.C. 2:90-1.”
The Department recognizes that permittees may be concerned that implementing this condition
will expand the burden of inspection activities and incur more costs and municipal resources.
However, it should be noted that there is no requirement for permittees to schedule separate
inspections as these road and roadside inspections can occur incidental to conducting other
47
ordinary municipal activities, including the inspection of storm drain inlets, street sweeping, or
police patrols. As such, the permittee should not incur any additional significant costs due to
inspection. And any road repairs would need to be conducted for public safety reasons, as well
as to ensure the proper operations and maintenance of the stormwater conveyance system.
New and existing Tier A permits will have 12 months from EDPA to comply with this
requirement.
3. Inspection and Maintenance of Stormwater Facilities Owned or Operated by the Permittee
(Part IV.F.3)
The 2004 and 2009 Tier A permits required permittees to ensure adequate long-term operation and
maintenance of stormwater facilities owned or operated by the municipality.
Consistent with, but more specific than the 2004 and 2009 permit requirements, the 2018 Tier A
permit required permittees to develop a program to ensure adequate long-term cleaning, operation,
and maintenance of all municipally owned or operated stormwater facilities under Minimum
Standards for Stormwater Facilities Maintenance in Part IV.C.1.a. which stated:
“The Tier A Municipality shall develop, update and implement a program to ensure adequate long-
term cleaning, operation and maintenance of all municipally owned or operated stormwater
facilities.
Stormwater facility inspection and maintenance must be performed pursuant to any
maintenance plans, or more frequently as needed, to ensure the proper function and operation
of the stormwater facility.
The Tier A Municipality shall maintain a log sufficient to demonstrate compliance with this
section; including but not limited to the stormwater facility inspected, location information of
the facility inspected (location information must be specific enough to locate and identify the
stormwater facility in the field; e.g., geographic coordinates), name of inspector, date of
inspection, findings, and any preventative and corrective maintenance performed.
The Tier A Municipality shall certify annually that municipally owned or operated stormwater
facilities are properly functioning.
If stormwater facilities were found not to be functioning properly and repairs were not made,
then necessary preventive and corrective maintenance shall be documented and prioritized, and
a schedule for such repairs shall be maintained. The Tier A Municipality shall prioritize this
schedule based upon but not limited to: (1) environmental, health and safety concerns; (2) the
findings of catch basin and storm drain inlet inspections performed pursuant to Part IV.B.5.b.ii,
above; (3) the findings of stream scouring inspections performed pursuant to Part IV.B.6.b,
above; and (4) to incorporate the findings pursuant to Part IV.C.2”
The 2018 Tier A permit also included specific requirements in this section for “Catch Basin and
Storm Drain Inlet Inspection and Cleaning” which stated:
“The Tier A Municipality shall inspect storm drain inlets and any associated catch basins that
it owns or operates and remove sediment, trash, or debris when present. Each catch basin and
inlet shall be inspected at least once every five years. The Tier A Municipality shall clean any
municipally owned or operated storm drain inlet or catch basin as frequently as necessary to
eliminate recurring problems and restore proper function.”
Under this permit condition, permittees were required to perform maintenance according to existing
48
maintenance manuals for specific infrastructure, or more frequently as needed to ensure the proper
function and operation of the stormwater facility, perform repairs as necessary, maintain logs to
document compliance, and certify compliance annually.
The 2009 Tier B permit required permittees to Ensure adequate long-term operation and
maintenance of BMPs on property owned or operated by the municipality.” The 2018 Tier B permit
expanded on this language under Minimum Standards for Post Construction Stormwater
Management in New Development and Redevelopment in Part IV.B.2 and Attachment E as
follows:
“The Tier B Municipality shall ensure, as set forth in Attachment E (Stormwater Facilities
Maintenance), adequate long-term cleaning, operation and maintenance of stormwater
management measures:
o Owned or operated by the Tier B Municipality; and
o Not owned or operated by the Tier B Municipality and not subject to the conditions of
another NJPDES stormwater permit.”
From Attachment E:
o “The Tier B Municipality shall develop, update and implement a program to ensure
adequate long-term cleaning, operation and maintenance of all municipally owned or
operated stormwater facilities as follows:
Stormwater facility inspection and maintenance must be performed pursuant to any
maintenance plans, or as needed to ensure the proper function and operation of the
stormwater facility (see );
The Tier B Municipality shall maintain a log sufficient to demonstrate compliance with
this section; including but not limited to the stormwater facility inspected, location
information of the facility inspected (location information must be specific enough to
locate and identify the stormwater facility in the field: e.g. geographic coordinates),
name of inspector, date of inspection, findings, and any preventative and corrective
maintenance performed. Example Maintenance Logs and Inspection Records forms
which are sufficient to demonstrate compliance with this section are available at ;
Certify annually that municipally owned or operated stormwater facilities are properly
functioning; and
If stormwater facilities were found not to be functioning properly and repairs were not
made, then necessary preventive and corrective maintenance shall be documented and
prioritized, and a schedule for such repairs shall be maintained.”
This renewal permit proposes to further clarify and expand the expected actions that are considered
adequate long-term cleaning, operation, and maintenance; the inclusion of inspection frequencies
of stormwater facilities to ensure better operation; clarification of the requirements for catch basins;
the addition of specific requirements for stormwater conveyance system inspection and cleaning;
inclusion of inspections for all other stormwater infrastructure; as well as retaining the requirement
maintain logs and records of cleanings and inspections of all facilities.
Revisions to this section also separate the requirements for inspecting inlets from inspecting catch
basins and clarify that inlets and catch basins are separate devices and only need to be cleaned
based on the results of the inspections if it is indicated that cleaning is necessary to remove
sediment, trash, or other debris to control it from entering the waters of the State, to eliminate
recurring problems, or maintain proper function. For guidance related to catch basin cleaning, refer
to the EPA Catch Basin Technology Overview and Assessment in the Highway Agency Guidance
document (https://www.nj.gov/dep/dwq/highway_guidance.htm
). The requirements in the renewal
49
permit state:
The permittee shall develop, update, and implement a program to ensure adequate long-term
cleaning, operation, and maintenance of all municipally owned or operated stormwater facilities,
which includes but is not limited to:
i. Storm Drain Inlet Inspection: The permittee shall inspect, at a minimum of once per year,
all storm drain inlets that it owns or operates;
ii. Storm Drain Inlet Cleaning and Maintenance: The permittee shall develop, update, and
implement a storm drain inlet cleaning and maintenance program. The program shall
establish the conditions under which a storm drain inlet must be cleaned, and maintenance
performed. Cleaning and maintenance shall be conducted, at a minimum, as frequently as
necessary to ensure that sediment, trash, or other debris is removed as necessary to restrict it
from entering the waters of the State; to eliminate recurring problems; and maintain proper
function;
iii. Catch Basin Inspection: The permittee shall inspect all catch basins that it owns or operates.
At a minimum, permittees who own or operate less than 1,000 catch basins shall inspect them
once per year. Permittees who own or operate 1,000 or more catch basins shall inspect a
minimum of 20% of the total or 1,000 per year, whichever is greater, rotating the schedule
in such a way that all catch basins are inspected at least once every five years on
approximately the same frequency;
iv. Catch Basin Cleaning: The permittee shall develop, update, and implement a catch basin
cleaning and maintenance program. The program shall establish when a catch basin must be
cleaned and maintained and include procedures for cleaning and maintenance. Cleaning and
maintenance shall be implemented as frequently as necessary to ensure, at a minimum, that
sediment, trash, or other debris is removed as necessary to control it from entering the waters
of the State; to eliminate recurring problems; and maintain proper function. (See EPA’s
guidance as noted above at
https://www.nj.gov/dep/dwq/highway_guidance.htm);
v. MS4 Conveyance Inspection and Cleaning: The permittee shall develop, update, and
implement a MS4 conveyance inspection, cleaning, and maintenance program. The program
shall establish when the MS4 conveyance must be cleaned and maintained to ensure proper
function and operation;
vi. Stormwater Infrastructure Inspection: (excluding infrastructure in i. v. above): The
permittee shall inspect all stormwater infrastructure that it owns or operates pursuant to
approved maintenance plans. If there are no approved maintenance plans for certain
stormwater infrastructure, the permittee shall inspect that infrastructure at least 4 times
annually, and after each rainstorm exceeding 1 inch of total rainfall, unless the NJ Stormwater
BMP Manual recommends a less frequent schedule;
vii. Stormwater Infrastructure Maintenance: (excluding infrastructure in i. v. above): The
permittee shall perform maintenance pursuant to approved maintenance plans, or more
frequently as needed, to ensure the proper function and operation. See
www.njstormwater.org; for maintenance guidance;
viii. Inspection/Maintenance Records: The permittee shall maintain a log sufficient to
demonstrate compliance with this section, including but not limited to the type of stormwater
50
facility; location information of the facility with geographic coordinates; name of inspector;
date of inspection; observations of the structural integrity; history of complaints; evidence of
current or previous flooding; any preventative and corrective maintenance performed; and
any additional information or findings. Example Maintenance Logs and Inspection Records
forms are available at www.njstormwater.org
under the maintenance guidance link; and
ix. Corrective Maintenance: If stormwater facilities are found not to be functioning properly,
corrective maintenance and repairs shall be completed as soon as practicable, but no later
than 90 days from discovery, unless another timeframe is authorized by the Department. The
permittee shall prioritize these activities based upon environmental, health and safety
concerns.
The changes proposed in this permit renewal are intended to ensure permittees are developing,
updating, and implementing a program that sufficiently ensures adequate long-term cleaning,
operation, and maintenance of all municipally owned or operated stormwater facilities.
Additionally, “storm drain inlet” has been defined in this permit to mean the point of entry into the
storm sewer system. This is important since some inlets do not have catch basins but still require
inspection and cleaning. The permittee must also ensure that any given catch basin or storm drain
inlet is cleaned as frequently as necessary to ensure proper function and operation. These
requirements are being included to ensure proper operation of these stormwater facilities, including
reducing and eliminating localized stormwater flooding.
Since these requirements were included in both the 2018 Tier A and B permits, no additional time
is necessary for new Tier A permittees to come into compliance, and therefore compliance with
these requirements is due on EDPA for all existing and new Tier A permittees.
4. Inspection and Maintenance of Stormwater Facilities Not Owned or Operated by the
Permittee (Part IV.F.4)
The 2009 Tier A permit required that permittees ensure adequate long-term operation and
maintenance of stormwater facilities not owned or operated by the municipality. The 2018 Tier A
permit retained this requirement, labeled as “Minimum Standards for Stormwater Facilities
Maintenance” with the enhancement that the permittees develop, update, implement and enforce a
program to ensure adequate long-term cleaning, operation and maintenance of all stormwater
facilities not owned or operated by the permittee and not subject to the conditions of another
NJPDES stormwater permit under the Other Control Measures section at Part IV.C.1.b. as follows:
The Tier A Municipality shall develop, update, implement and enforce a program to ensure
adequate long-term cleaning, operation and maintenance of stormwater facilities not owned or
operated by the Tier A Municipality, not subject to the conditions of another NJPDES
stormwater permit and constructed after February 7, 1984.
i. The Tier A Municipality shall ensure that stormwater facility maintenance is performed
pursuant to any maintenance plans, or more frequently as needed to ensure the proper
function and operation of the stormwater facility. See
www.nj.gov/dep/stormwater/maintenance_guidance.htm
; and
ii. The Tier A Municipality shall maintain a log sufficient to demonstrate compliance with
this section; including but not limited to the actions taken by the municipality to enforce
compliance with the long-term cleaning, operation and maintenance program; the
51
stormwater facility that was the subject of the action; location information of the facility
that was the subject of the action (location information must be specific enough to locate
and identify the stormwater facility in the field; e.g. geographic coordinates); the name of
person taking the action; the date of the action; and the findings. Example Maintenance
Logs and Inspection Records forms which are sufficient to demonstrate compliance with
this section are available at www.nj.gov/dep/stormwater/maintenance_guidance.htm
.”
The 2009 Tier B permit required that those permittees ensure adequate long-term operation and
maintenance of BMPs on property not owned or operated by the municipality and the 2018 Tier B
permit also continued this requirement in Part IV, Section B.2.j. which states:
The Tier B Municipality shall ensure, as set forth in Attachment E (Stormwater Facilities
Maintenance), adequate long-term cleaning, operation and maintenance of stormwater
management measures:
i. (Owned or operated by the Tier B Municipality; and)
ii. Not owned or operated by the Tier B Municipality and not subject to the conditions of
another NJPDES stormwater permit.
And from Attachment E of the 2018 Tier B permit which states:
The Tier B Municipality shall develop, update, implement and enforce a program to ensure
adequate long-term cleaning, operation and maintenance of stormwater facilities not owned or
operated by the Tier B Municipality; not subject to the conditions of another NJPDES
stormwater permit; and constructed after February 7, 1984; as follows:
i. Ensure that stormwater facility maintenance is performed pursuant to any maintenance
plans, or more frequently as needed, to ensure the proper function and operation of the
stormwater facility (see www.njstormwater.org/maintenance_guidance.htm
); and
ii. Maintain a log sufficient to demonstrate compliance with this section; including but not
limited to the actions taken by the municipality to enforce compliance with the long-term
cleaning, operation and maintenance program; the stormwater facility that was subject of
the action; location information of the facility that was subject of the action (location
information must be specific enough to locate and identify the stormwater facility in the
field; e.g. geographic coordinates); the name of the person taking the action; the date of the
action; and the findings. Example Maintenance Logs and Inspection Records forms which
are sufficient to demonstrate compliance with this section are available at
www.njstormwater.org/maintenance_guidance.htm
.”
This permit renewal has moved these requirements to the section labeled “Inspection and
Maintenance of Stormwater Facilities Not Owned or Operated by the Permittee” which is now
under the section Minimum Standards for Pollution Prevention / Good Housekeeping for Municipal
Operators. This permit renewal has retained similar language from the 2018 Tier A permit, but it
has been updated to include a minimum frequency of inspection and maintenance of stormwater
facilities not owned or operated by the permittee. The renewal permit language is as follows:
The permittee shall develop, update, implement and enforce a program to ensure adequate
long-term cleaning, operation and maintenance of stormwater facilities not owned or operated
by the permittee, not subject to the conditions of another NJPDES stormwater permit and which
were constructed after February 7, 1984.
The permittee shall ensure that stormwater facilities not owned or operated by the permittee
are inspected and maintained pursuant to approved maintenance plans, or more frequently as
52
needed to ensure the proper function and operation of the stormwater facility, but at a frequency
of not less than once per year.”
This requirement is sometimes assumed to be applicable only to privately owned or operated
facilities approved under the permittee’s Post Construction Stormwater Management program
(typically after March 1, 2004) and only to stormwater facilities that are connected to the
permittee’s MS4. This renewal permit clarifies that the permittee’s obligation to enforce cleaning,
operation, and maintenance also encompasses the stormwater facilities approved by the permittee
after February 7, 1984, regardless of location within the municipality, which is consistent with state
and Federal regulations.
The maintenance program requirements of this permit renewal are consistent with, but more
specific than the 2018 Tier A and Tier B permit requirements, and state:
The permittee shall ensure that proper maintenance includes cleaning and removal of solid
and floatable materials, including trash/litter, excess leaves or grass clippings, branches, logs,
any other debris, or excess growth. These materials have the potential to impede the proper
function and/or restrict flow causing flooding or excessive discharge velocity or may be
discharged to the receiving waters. The permittee may require the owners or operators of these
facilities to take measures to prevent the accumulation, discharge, or other hazards caused by
such debris in the stormwater facilities (e.g., catch basins along roads and parking areas, and
detention basins).
The permittee shall maintain a log sufficient to demonstrate compliance with this section, including,
but not limited to, the actions taken by the permittee to enforce compliance with the long-term
cleaning, operation, and maintenance program; the stormwater facility that was the subject of the
action; location information of the facility with geographic coordinates; the name and title of person
responsible for enforcement; the date of the action; and the findings.
The permittee shall maintain copies of all maintenance plans, as defined in Notes and Definitions,
Part IV.B.1.a.vi, of this permit, for stormwater facilities approved by the municipality. The
permittee shall provide copies of these maintenance plans to the Department upon request.”
In order to guide operations and maintenance of a designed system, a maintenance plan is required
to be developed for stormwater facilities. A maintenance plan is defined in this draft permit in the
Notes and Definitions section as follows:
“Maintenance plan” means a maintenance plan pursuant to N.J.A.C. 7:8-5.2(b) and 5.8
prepared by the design engineer for the stormwater management measures incorporated into
the design of a major development.
Note that a maintenance plan is not an operation and maintenance manual as described in the
NJPDES rules at N.J.A.C. 7:14A-6.12. While the Tier A Municipality is required to comply with
applicable operation and maintenance requirements of N.J.A.C. 7:14A-6.12(a), the Tier A
Municipality is exempt from the operations and maintenance manual requirements of N.J.A.C.
7:14A-6.12(c).
This renewal permit continues to require that Tier A permittees obtain geospatial location
information for privately owned stormwater facilities. This requirement is also included under the
Watershed Improvement Inventory in Part IV.H of the permit, as described in section H of this fact
sheet, where privately owned stormwater facilities need to be inventoried by the permittee and
53
included on the electronic map. Additional information regarding existing mapping of stormwater
management facilities can be found in that section, below, of this fact sheet.
Since the Department’s adoption of the 1983 Stormwater Management rules at N.J.A.C. 7:8, Tier
A and Tier B permittees were required to adopt Stormwater Control Ordinances to enforce the
maintenance duty upon private developments, with the option of including conditions to assess
penalties on private entities negligent of maintenance and perform maintenance work and back
charge maintenance costs to those negligent private owners. Therefore, this renewal permit
readdresses this enforcement privilege and obligation that has been exercised by many permittees
upon privately owned stormwater facilities prior to 2004. Moreover, the provisions of the
Stormwater Management rule from 1983 onward and related to ensuring proper operation and
maintenance of privately owned or operated stormwater facilities apply to stormwater facilities
approved by permittees regardless of their relationship to a MS4. Proposed Part IV.C.1.b
establishes the date frame “constructed after February 7, 1984” to accommodate the time needed
for municipalities to adopt stormwater ordinances following the February 7, 1983 adoption of first
adopted Stormwater Management rules.
The New Jersey Hydrologic Modeling Database (or H&H Database) is posted online and
encompasses several decades of data collection by NJ Soil Conservation Districts and the New
Jersey Department of Agriculture. This database contains a wealth of information regarding
stormwater management basins and data can be downloaded based on location. See
https://hydro.rutgers.edu/ to view the database map or
https://hydro.rutgers.edu/public_data/ to
download data in an Excel format. The information in this database may help permittees to identify
stormwater basins in the municipality that they were not aware of. This will help to identify basins
that may require maintenance and can help the permittee to develop a more robust inventory as a
result.
Since these requirements were included in both the 2018 Tier A and B permits, no additional time
is necessary for new Tier A permittees to come into compliance, and therefore compliance with
these requirements is due on EDPA for all existing and new Tier A permittees.
5. Municipal Maintenance Yards and Other Ancillary Operations (Part IV.F.5)
The requirements pertaining to municipal maintenance yards and other ancillary operations were
included in Part IV.B.5.c of the 2018 Tier A permit, with detailed best management practices in
Attachment E of that permit. These activities could be otherwise regulated under individual
industrial stormwater permits, but the Department has determined that this general permit is the
most efficient and appropriate means to regulate a large number of similar dischargers (see also
N.J.A.C. 7:14A-6.13).
Consistent with 40 CFR. 122.34(b)(6) and N.J.A.C. 7:14A-25.6(b)7, each iteration of New Jersey’s
Tier A MS4 NJPDES permit since 2004 has included requirements related to municipal
maintenance yard (MMY) operations. N.J.A.C. 7:14A-25.6(b)7 states:
“Maintenance yards and highway service areas: The permittee shall develop and implement an
operation and maintenance program that prevents or reduces pollutant runoff from maintenance
yards and highway service areas owned or operated by the permittee.”
In Part IV.F.5 of this permit renewal, these requirements, representing common activities at MMYs,
are presented under the heading “Municipal Maintenance Yards and Other Ancillary Operations.”
This section of the permit has been expanded to incorporate all applicable BMPs and control
54
measures which were previously included in Attachment E of the 2018 Tier A permit, and since
these conditions have been moved from Attachment E into the body of the permit, Attachment E is
no longer necessary and has been removed from this renewal permit.
Based on information from MS4 stormwater compliance audits discussed above, it was determined
that the 2018 Tier A permit did not accurately regulate all the activities that may be exposing
pollutant sources to stormwater at MMY locations. This permit renewal proposes to remedy this
gap by expanding this section and including additional BMPs or control measures that must be
implemented to minimize or eliminate pollutant source exposure to stormwater for each activity.
The Department has determined that expanding coverage under this permit renewal for additional
activities commonly occurring at MMYs is appropriate since such activities can be significant
contributors of pollutants to surface water if not managed properly (see N.J.A.C. 7:14A-24.2(a)7).
Therefore, this permit renewal incorporates enhanced requirements for documenting each MMY
and ancillary operation in the Stormwater Pollution Prevention Plan (SPPP); providing secondary
containment for bulk liquid material storage tanks; ensuring proper storage of aggregate material
and finished compost (with no processing activities); setting a time limit on and ensuring proper
storage of construction and demolition waste, wood waste, and yard trimmings (with no processing
activities); storing cold patch asphalt in a permanent structure or covered on an impervious surface;
storing scrap tires in a covered container or under cover; setting a time limit on and ensuring proper
storage of inoperable vehicles or equipment; and ensuring refuse containers and dumpsters are kept
covered.
The permit renewal enhancements differentiate between aggregate material (e.g., sand, gravel,
stone, and topsoil) and solid waste by setting a specific time limit on the storage of solid waste. The
storage of aggregate material, wood chips, and finished compost does not have a time limit;
however, the storage of construction and demolition waste, wood waste, and yard trimmings is only
authorized for a limited time. The discharge of stormwater from the processing of any of these
materials is not authorized under this renewal permit and sites conducting processing activities will
need to apply for an applicable industrial stormwater permit. Further, Tier A permittees are not
exempt from the requirement to apply for an industrial stormwater permit for any activity addressed
in this section if required to do so, for due cause, by the Department (See N.J.A.C. 7:14A-6.13).
Wood waste recycling and leaf composting are regulated industrial activities that requires a
NJPDES stormwater permit. Wood waste recycling and leaf composting operations at MMYs were
only authorized under the 2018 Tier A permit provided there were no discharges to surface water
from those activities. However, this was not the case for any municipal wood waste recycling or
leaf composting operations inspected during the MS4 stormwater compliance audits. Based on the
lack of ability of the MMYs to prevent discharges to surface water from these industrial activities,
the Department determined that these activities were not being regulated adequately under the Tier
A permit and that it was necessary to draft a new stormwater general permit with appropriate BMPs
to regulate those discharges to surface water. Thus, the discharge of stormwater from Tier A MMYs
and ancillary operations that process wood waste, yard trimmings, and leaf compost will no longer
be authorized under the Tier A permit upon the effective date of this permit renewal. Those MMY’s
must obtain reauthorization for those activities via the new Wood Waste Recycling and Leaf
Composting (WRC) Stormwater General Permit Authorizations regulating recycling/composting
activities, which will be made available to each municipality that performs these activities. This
new WRC permit was issued draft on July 21, 2022 and will be issued final no later than the
issuance of the final Tier A permit renewal.
In addition, Roadside Vegetation Management has been renamed Herbicide Application
55
Management and moved from this section in the 2018 Tier A permit to Part IV.F.2.a. of this renewal
permit under Community-wide Measures and is discussed in more detail in that section above.
Inclusion of this more comprehensive set of activities for MMYs is an important component of this
permit renewal regarding the protection of water quality and is consistent with 40 CFR
122.34(b)(6)(ii) which states:
…EPA recommends that the permit address the following: . . . controls for reducing or
eliminating the discharge of pollutants from . . . maintenance and storage yards, fleet or
maintenance shops with outdoor storage areas, salt/sand storage locations and snow disposal
areas . . . procedures for properly disposing of waste removed from the separate storm sewers
and areas listed above (such as dredge spoil, accumulated sediments, floatables, and other
debris) . . .”
The Department is proposing to expand the requirements for permittees to cover additional source
materials at their municipal maintenance yards. These changes are based on the MS4 stormwater
compliance audits of Tier A permittees which confirmed that many permittees are storing materials
such as cold patch asphalt and scrap tires uncovered in these yards. Permittees already are required
to employ federally required good housekeepingmeasures for small MS4 compliance at their
maintenance yards to eliminate run-on/runoff from materials they store. Permittees should not incur
any additional significant costs as they are already managing these materials and this permit
condition is clarifying those handling procedures. Additionally, these source material piles are
relatively small and the cost of covers or tarps would be insignificant in comparison to the cost of
compliance with a NJPDES industrial stormwater discharge permit, which would otherwise be
required for piles that remain exposed. These piles would be considered sources of stormwater
discharges associated with industrial activity requiring an industrial stormwater permit.
The BMPs in this renewal permit are intended to improve stormwater quality through the
implementation of techniques to minimize the exposure of pollutants to stormwater as follows:
Documenting Best Management Practices (BMPs) at all MMYs
Properly implemented good housekeeping measures and BMPs can eliminate or minimize
contact between stormwater and source materials. It was observed during MS4 stormwater
compliance audits of Tier A permittees that some permittees had more than one MMY or were
performing ancillary operations at various locations. Often, Department staff were unaware of
these locations unless municipal staff mentioned them. To remedy this gap, an enhancement
added to Part IV.F.5.a of this section requires each individual MMY and ancillary operation to
be identified with its own form in the SPPP, including a description of the site-specific activities
and associated BMPs.
Existing Tier A permittees shall implement this requirement upon EDPA. New Tier A
permittees shall include these updated MMY forms in the SPPP by EDPA + 12 months.
Site Inspections
There is no change from the 2018 Tier A permit regarding monthly site inspection
requirements. The requirement shall continue for Tier A permittees to track site inspections on
a maintenance log. The maintenance log must contain (at a minimum) a record of inspections
of all operations detailed in Part IV.F.5, including dates and times of the inspections, the name
of the person conducting the inspection and relevant findings. This maintenance log must be
56
kept on-site with the SPPP and made available to the Department upon request.
Existing Tier A permittees shall implement this requirement upon EDPA since there is no
change from the 2018 Tier A permit requirements. New Tier A permittees shall implement this
requirement upon EDPA + 12 months.
Inventory List
There is no change from the 2018 Tier A permit regarding the inventory list requirements. The
requirement shall continue for Tier A permittees to implement good housekeeping procedures
including maintaining an inventory of materials and machinery which could be a source of
pollutants in stormwater discharges.
Existing Tier A permittees shall implement this requirement upon EDPA since there is no
change from the 2018 permit requirements. New Tier A permittees shall implement this
requirement upon EDPA + 12 months.
Container Labels
There is no change from the 2018 Tier A permit regarding container label requirements. The
requirement shall continue for Tier A permittees to properly label all containers with labels that
are legible, clean, and visible. Permittees shall keep containers in good condition, protected
from damage and spillage, and tightly closed when not in use.
Existing Tier A permittees shall implement this requirement upon EDPA since there is no
change from the 2018 permit requirements. New Tier A permittees shall implement this
requirement upon EDPA + 12 months.
Spill Kits
There is no substantial change from the 2018 Tier A permit regarding the handling of spills.
The requirement shall continue for Tier A permittees to conduct cleanups of spills of liquids or
dry materials immediately after discovery. The permit renewal now includes the following
sentence: “Spills that are suspected to be a threat to human health or the environmental shall
be immediately reported to the NJDEP Hotline at 1-877-WARNDEP (1-877-927-6337).” The
permit retains the following requirements from the 2018 Tier A permit: All spills shall be
cleaned using dry cleaning methods only. Clean up spills with a dry, absorbent material (i.e.,
kitty litter, sawdust, etc.) and sweep the rest of the area. Dispose of collected waste properly.
Store clean-up materials, spill kits and drip pans near all liquid transfer areas, protected from
rainfall.
Existing Tier A permittees shall implement this requirement upon EDPA. New Tier A
permittees shall implement this requirement upon EDPA + 12 months.
Bulk Liquid Material
This is a new requirement for all Tier A permittees. Secondary containment of the containers
utilized in the normal course of storage, transfer, or use, is necessary for preventing leaks of
bulk liquid materials from becoming discharges. Secondary containment is also required to trap
leaks and leakage where they can be cleaned up and removed prior to their escape onto the
land, groundwaters or surface waters of the State. Tier A permittees shall have secondary
57
containment (e.g., spill containment dikes, double walled tanks with no exposed valves and
hoses, etc.) for all aboveground storage tanks containing bulk liquid materials (including but
not limited to gasoline, diesel fuel, heating oil, hydraulic oil, used oil and liquid de-icing
materials). The containment area must be impervious and be able to contain the volumetric
capacity of at least 110% of the largest tank’s capacity within the containment area. The
containment area must be constructed so that no volume of bulk liquid material can escape
through drains, storm sewer systems, or to the surface waters or ground waters of the state. All
accessory pipes, hoses, valves, and pumps must also be located within the containment area or
otherwise stored in a manner with no exposure to stormwater. It is recommended that the
secondary containment area be protected from the weather with a metal roof to prevent
stormwater from accumulating in the containment structure so that there is no need to determine
of that accumulated stormwater can be discharged, as discussed below.
Existing and new Tier A permittees shall implement this requirement by EDPA + 12 months.
Fueling Operations
There is no change from the 2018 Tier A permit regarding fueling operations. Stormwater
contamination can occur from residual spillage that may occur from topping off fuel tanks, not
being attentive during loading and unloading procedures, or improper cleanup after a spill
occurs. This requirement shall continue for Tier A permittees to establish, maintain, and
implement standard BMPs for vehicle fueling; receipt of bulk fuel deliveries; and inspection
and maintenance of storage tanks, including the associated piping and fuel pumps.
Existing Tier A permittees shall implement this requirement upon EDPA. New Tier A
permittees shall implement this requirement by EDPA + 12 months.
Discharge of Stormwater from Secondary Containment
There is no change from the 2018 Tier A permit regarding discharge of stormwater from secondary
containment. This requirement shall continue for Tier A permittees to implement BMPs for
discharges of stormwater from secondary containment systems (e.g., waste oil storage). Permittees
may only discharge stormwater accumulated in a secondary containment area if it can be
ascertained that the stormwater has not come into contact with stored product.
Since these requirements do not require any additional equipment and should not require any
increase in staff time to restrict the discharge from a secondary containment system, no
additional time should be necessary for new or existing Tier A permittees to come into
compliance, and therefore compliance with these requirements is due on EDPA for all existing
and new Tier A permittees.
Vehicle/Equipment Maintenance and/or Repair
There is no change from the 2018 Tier A permit regarding vehicle and equipment maintenance
and/or repair. This requirement continues for Tier A permittees to implement BMPs for vehicle
and equipment maintenance and/or repair. When stormwater is exposed to pollutants associated
with these activities it can become polluted with toxic or other deleterious materials (e.g.,
petroleum hydrocarbons).
Since compliance with this requirement would only entail the use of minimal and inexpensive
equipment, such as portable tents or covers, and drip pans, and since the discharge of vehicle
58
fluids would be considered an illegal unpermitted discharge, existing and new Tier A
permittees shall implement this requirement upon EDPA.
Wash Wastewater Containment
There is no change from the 2018 Tier A permit regarding wash wastewater containment. This
requirement continues to require permittees to manage any equipment and vehicle washing
activities so that there are no unpermitted discharges of wash wastewater to storm sewer inlets
or to waters of the State. A permittee that cannot discharge wash wastewater to a sanitary sewer
may temporarily store wash wastewater in a containment structure prior to proper disposal
while following the conditions in the permit for:
o Structural Inspections;
o Visual Inspections;
o Overfill Prevention;
o Leak Remediation;
o Pump-outs (including Clean-outs);
o Annual Engineer’s Certification; and
o Recordkeeping
The wash wastewater containment structure language provides Tier A permittees that are
otherwise unable to manage equipment and vehicle washing activities without unpermitted
discharges of wash wastewater to storm sewer inlets or to waters of the State with the option
to temporarily contain wash wastewater prior to proper disposal. Such containment structures
are typically installed at public works facilities which are not connected to a sanitary sewer
system.
Permittees are required to maintain all logs, inspection records and certifications on-site and
available to the Department upon request.
The Department maintains that these conditions provide prescriptive, pragmatic conditions that
prevent the inappropriate discharge of equipment and vehicle wash wastewater. Since vehicle
washing can be done at commercial wash locations or can be contained on impervious surfaces
with booms and vacuumed up without discharge to surface or ground waters of the state, and
since the discharge of vehicle wash wastewater would be considered an illegal unpermitted
discharge, existing and new Tier A permittees shall implement this requirement upon EDPA.
Salt and Other Granular De-icing Material Storage and Handling
There is no change from the 2018 Tier A permit requiring permittees to install a permanent
structure for salt and other granular de-icing material storage and handling to prevent
stormwater from coming into contact with salt and de-icing material, with the exception of the
text “other granular” being added to this condition.
When salt and other de-icing materials are stored outside and uncovered, they can easily
dissolve and be transported by stormwater to the surface waters and ground waters of the state.
Temporary outdoor storage is only allowable when a permanent structure is under construction,
repair, or replacement, and provided certain conditions are met. Permanent structure is
explicitly defined in Part IV, Notes and Definitions section of the permit. Requiring indoor
storage of salt and de-icing materials is an effective pollution prevention technique which helps
to eliminate pollutant loadings to surface and ground water. The Departments goal is to ensure
59
that these materials are properly handled, stored, or covered, so that they are not transported by
stormwater and discharged to surface and ground waters of the state.
Existing Tier A permittees shall implement this requirement upon EDPA. New Tier A
permittees shall implement this requirement by EDPA + 36 months.
Aggregate Material, Wood Chips and Finished Compost Storage
Storage for aggregate materials and construction debris was addressed in the 2018 Tier A
permit’s Attachment E. This condition has been modified and incorporated into the body of the
permit renewal. This renewal permit authorizes permittees to store aggregate material (e.g.,
sand, gravel, stone, and topsoil) provided these materials are stored and managed with
appropriate stormwater pollution prevention BMPs. Since construction debris is classified as
solid waste and there are requirements under the Solid Waste program restricting the temporary
storage of these materials, they are no longer addressed in this section and have been moved to
the section below that includes other solid waste materials, such as wood waste and yard
trimmings. Also, wood chips and finished compost have been added to this section as they are
not considered to be solid waste.
In addition, this renewal permit prohibits the processing of materials (i.e., composting,
chipping, grinding, screening, and/or size reducing.) The discharge of stormwater from the
processing of materials is not authorized under this Tier A permit. Facilities conducting
processing activities shall contact the Industrial Stormwater Permitting Unit for information
regarding obtaining the applicable NJPDES individual or general industrial stormwater
discharge permit.
For existing Tier A permittees, this condition continues the implementation of measures to
minimize stormwater run-on and pollutant run-off via surface grading, dikes and/or berms
(which may include sandbags, hay bales and curbing) or three-sided storage bays. Other
measures, such as the 50-foot setback from surface water bodies, storm sewer inlets and/or
ditches or other stormwater conveyance channels, also continue to apply.
Inclusion of these enhanced requirements serve to improve the permit by specifying practical
measures to minimize stormwater contact with aggregate material, wood chips, and finished
compost storage material. The Departments goal is to ensure that these materials are properly
handled and stored so that contact with stormwater can be minimized.
Existing Tier A permittees shall implement this requirement upon EDPA. New Tier A
permittees shall implement this requirement by EDPA + 6 months.
Cold Patch Asphalt Storage
This is a new requirement for all Tier A permittees to store cold patch asphalt in a permanent
structure or on an impervious surface and covered with a waterproof material (i.e., tarpaulin or
10-mil plastic sheeting) and contained (e.g., contained by berms) to control leachate and
stormwater run-on or run through. MS4 Stormwater compliance audits confirmed that many
permittees are storing cold patch asphalt uncovered in their MMYs, and some cold patch piles
have been observed with a rainbow sheen in the runoff. Review of some Material Safety Data
Sheets showed residual concentrations of benzene as part of the composition of cold patch
asphalt.
60
The Department maintains that these conditions provide prescriptive, pragmatic conditions that
prevent the inappropriate discharge of benzene from cold patch asphalt stockpiles.
Since cold patch stockpiles are generally small and can be readily stored in an existing
permanent structure or easily contained on an impervious surface with the appropriate type of
cover, and since the discharge of benzene would be considered an illegal unpermitted
discharge, existing and new Tier A permittees shall implement this requirement upon EDPA.
Street Sweepings and Storm Sewer Clean-out Material Storage
There is no significant change from the 2018 Tier A permit regarding street sweepings and
storm sewer clean-out material storage, except for the added enhancement for materials that
are bermed on an impervious surface be stored under a waterproof cover. Part IV.F.5.n provides
BMPs for the temporary storage of street sweepings, storm sewer and catch basin clean-out
materials, stormwater management basin clean-out materials and other similar materials that
may be collected during road cleanup operations. These BMPs do not address materials such
as liquids, wastes which are removed from municipal sanitary sewer systems, or material which
constitutes hazardous waste in accordance with N.J.A.C. 7:26G. Any of these materials,
collected in conformance with this BMP, must be stored in leak-proof containers or on an
impervious surface that is contained (e.g., bermed) and covered with a waterproof material (i.e.,
tarpaulin or 10-mil plastic sheeting) to control leachate and stormwater run-on or run-through;
and be removed for disposal within six (6) months of placement into storage.
Inclusion of this change serves to improve the permit and protect surface and ground water
quality by specifying another practical measure to minimize stormwater contact with these
materials. The Departments goal is to ensure that these materials are properly handled and
stored so that contact with stormwater that is discharged to surface and ground waters can be
minimized. Existing Tier A permittees shall implement this requirement upon EDPA. New Tier
A permittees shall implement this requirement by EDPA + 6 months.
Construction and Demolition Waste, Wood Waste, and Yard Trimmings Storage
Many Tier A permittees provide yard trimmings and wood waste pick-up as part of their
municipal services; thus, management of these materials was addressed in the 2018 Tier A
permit. Stormwater discharges from these activities at MMYs were authorized under the 2018
Tier A permit, provided that certain BMPs were followed. However, based on observations
made during the MS4 stormwater compliance audits, the current BMPs are not protective
enough and require further enhancement. In addition, because the Department determined that
similar BMPs are required, construction and demolition waste is also included in this section.
This permit renewal enhancement authorizes permittees to temporarily store rubble such as
asphalt millings, asphalt pavement, concrete, brick, block, and asphalt-based roofing scrap, and
vegetative waste such as wood waste and yard trimmings, provided these materials are:
Stored a minimum of 50 feet from surface water bodies, storm sewer inlets, and/or ditches or
other stormwater conveyance channels;
Stored in a manner as to minimize stormwater run-on and pollutant run-off via surface grading,
dikes and/or berms (which may include sandbags, hay bales and curbing, among others) or
three-sided storage bays. Where possible the open side of storage bays shall be situated on the
61
upslope. The area in front of storage bays and adjacent to storage areas shall be swept clean
after loading/unloading;
Removed within six (6) months of placement into storage; and
Not Being Processed (i.e., composting, chipping, grinding, screening, and or size reducing).
The discharge of stormwater from the processing of these materials is not authorized under this
permit. Please see below for additional permitting information for these activities.
Originally included in Attachment E of the 2018 Tier A permit, the requirement that road
millings to be managed in conformance with the Division of Solid and Hazardous Waste’s
(DSHW’s) March 2013 “Recycled Asphalt Pavement and Asphalt Millings (RAP) Reuse
Guidance” no longer applies because this document contained guidance on alternate uses for
RAP and no guidance on the proper storage of RAP at municipal maintenance yards. In
addition, the NJDEP Science Advisory Board’s 2019 report on asphalt millings determined that
RAP is not specifically defined in any of New Jersey’s regulations, and the definitions and
requirements for RAP in this guidance document is inconsistent with other State agency
guidance; thus, this RAP Reuse Guidance document was removed from the DSHWs webpage.
Also, the Division of Land Use Regulation reference has been removed because it was
redundant. This reference was included in Attachment E of the 2018 Tier A permit when the
requirements for aggregate storage at municipal maintenance yards were first added. All Tier
A permit iterations since the initial 2004 permit issuance have maintained the statement “In
accordance with N.J.A.C. 7:14A-6.2(a)7, this permit does not authorize any infringement of
State or local law or regulations;” thus, the Division of Land Use Regulation reference was
deemed unnecessary.
Existing Tier A permittees shall implement this requirement upon EDPA. New Tier A
permittees shall implement this requirement by EDPA + 6 months.
Scrap Tires
While many Tier A municipalities store scrap tires at their MMYs, management of this
stormwater pollution source material was not addressed in the 2018 Tier A permit. MS4
stormwater compliance audits confirmed that many permittees are storing scrap tires uncovered
in their yards. This new condition of the permit renewal requires Tier A permittees to cover
scrap tires with a tarp on an impervious surface or in a covered container or enclosure to prevent
the exposure to stormwater.
Since compliance with this requirement would only entail the use of minimal and inexpensive
equipment, such as tarps or covered containers, existing and new Tier A permittees shall
implement this requirement upon EDPA.
Inoperable Vehicles or Equipment
While many permittees store inoperable vehicles or equipment at their MMYs, management of
these stormwater pollution sources was not addressed in the 2018 Tier A permit. Tier A MS4
stormwater compliance audits confirmed that many permittees are storing vehicles and/or
equipment in various states of disrepair in their maintenance yards. This permit renewal
authorizes permittees to temporarily store inoperable vehicles or equipment for up to six (6)
months, provided portable tents or covers are placed over and drip pans under any leaking
vehicle or equipment, and use designated areas away from storm drains for the storage of
62
inoperable vehicles or equipment. Monthly inspections are required to check vehicles and
equipment for leaks and filled drip pans in compliance with the Site Inspections requirement
in section IV.F.5.b of the renewal permit.
Since compliance with this requirement would only entail the use of minimal and inexpensive
equipment, such as portable tents or covers, and drip pans, and since the discharge of vehicle
fluids would be considered an illegal unpermitted discharge, existing and new Tier A
permittees shall implement this requirement upon EDPA.
Refuse Containers and Dumpsters
Existing Tier A Municipalities already are required to follow good housekeeping practices at
their municipal maintenance yards to eliminate run-on/run-off from other stored materials. The
2018 Tier A permit requires onsite trash to be stored in leak-proof containers or on an
impervious surface that is contained (e.g., bermed) to control leachate and litter. This permit
renewal enhances the requirements for refuse containers and dumpsters by requiring permittees
to ensure that dumpsters and outdoor refuse containers exposed to stormwater at their MMYs
are kept covered. This serves to prevent the spilling, dumping, leaking, or discharging of
liquids, semi-liquids, or solids from the containers. This measure is not intended for temporary
demolition containers (e.g., rubble or construction waste, and wood waste) or containers that
hold large bulky items (e.g., furniture), provided they do not contain putrescible waste.
Since compliance with this requirement would only entail the use of minimal and inexpensive
equipment, such as portable tents, covers or tarps, and since the discharge of stormwater that
had become exposed to source materials would be considered an illegal unpermitted discharge,
existing and new Tier A permittees shall implement this requirement upon EDPA.
6. Stormwater Program Coordinator Training (Part IV.F.6)
Since the 2004 Tier A MS4 permit, the Department has received feedback from permittees and
NJDEP Compliance and Enforcement staff requesting training and guidance for Stormwater
Program Coordinators (SPCs) to better understand their responsibilities in overseeing and
implementing their stormwater programs. Since 2016, the Department has also conducted MS4
stormwater compliance assistance audits of several Tier A municipalities during which the
permittee has demonstrated inconsistent understanding of permit conditions and Best Management
Practices. In addition, upon SPC staff turnover, the MS4 unit and NJDEP Compliance and
Enforcement staff have received requests from individuals who are new to the SPC role asking for
clarification and assistance with their program responsibilities.
In response to these requests and observations, the Department will provide training for SPCs with
details related to the permit requirements and due dates for actions and submissions, SPC
responsibilities, including webpage postings, employee training, and annual MSRP reporting
requirements. The Department will notify all SPCs of record via email of the scheduled dates of
the training.
The Department will conduct this free training via an interactive webinar or in person sessions at
least twice per year.
Current SPCs are required to attend this training within EDPA + 36 months and once per permit
cycle thereafter. Upon commencement of duties of a new SPC, the permittee shall notify the
Department of the new SPC as per the conditions set forth in Part IV.A.1.e. and ensure that the new
63
SPC attends the next available SPC training session. The recording of the latest SPC training
sessions will be posted on the MS4 Tier A webpage for informational purposes between training
sessions.
7. Annual Employee Training (Part IV.F.7)
Since the issuance of the 2004 Tier A MS4 permit, the Department has required training of
municipal staff whose job responsibilities include activities required by the stormwater permit.
Training on certain topics was required every year while other the training on other topics was
required every other year. The Department is now proposing that training be conducted on all
topics each year, which changes the frequency of training for those topics that had previously only
been required every two years. The 2018 Tier A permit requires municipalities to provide employee
training on ten topics, with training on three of those topics required annually and the others every
two years. However, one of the three annual topics is on the Stormwater Pollution Prevention Plan
(SPPP), which encompasses all of the biennial topics, resulting in effectively requiring annual
training on those biennial topics. Additionally, many municipalities have had a number of permit
deficiencies noted during the MS4 stormwater compliance audits, and the Department has
determined that additional training will help resolve some of these deficiencies.
This change in the required training schedule is being made in acknowledgement of the
‘overlapping’ annual and biennial training requirements of the 2018 Tier A permit. This change in
frequency will also promote further compliance under the pollution prevention and good
housekeeping minimum control measures to the maximum extent practical under federal
requirements. Municipalities should not see any significant increase in cost, as they already conduct
annual training for some topics, and the annual training would cover some topics that were
inadvertently listed as biennial but covered annually during the SPPP training. Annual training also
supports the annual reviews/updates that municipalities make to the SPPP every year and will
ensure that staff is trained using the most current information. The order and naming of training
categories differ slightly as noted in the chart below, e.g., Yard Waste Collection Program training
is now included with the other Community-wide Measures.

Training shall occur annually and shall include the following topics, at a minimum, commensurate with an
employee’s title and duties. Training for new employees shall occur within three months of commencement
of duties. In order to assist permittees in meeting training requirements; the Department has posted a
Stormwater Training link to training materials at www.nj.gov/dep/stormwater/training.htm.
This link will
continue to be updated by the Department as training resources are developed or identified. In summary,
municipal employee training must cover the following topics, at a minimum, and shall occur at least once
every year:
SPPPProvide training on the content of the current SPPP, applicable recordkeeping
requirements, and provide detailed training to employees on any specific component applicable
to their title and duties;

Development and Redevelopment
65
Part G.1 of the permit);
Outfall Pipe Stream Scouring Detection and Control Provide training on how to inspect,
identify, correct, and document outfall pipe stream scouring and contributing factors. (See Part
G.2 of the permit);
Illicit Discharge Detection and Elimination Provide training on how to inspect, identify,
and eliminate illicit connections, and how to document the actions taken, and provide training
on the details of the program including investigation techniques, physical observations, and

https://www.epa.gov/npdes/national-menu-best-management-practices-bmps-stormwater
(See Part G.3 of the permit); and
Watershed Improvement Plan Provide training on the requirements for developing a
Watershed Improvement Plan, explaining the overall purpose and components of the plan. (See
Part H of the permit)
Increased employee awareness through training will increase the effectiveness of the stormwater
program and will ensure each employee is consistently implementing the permit conditions
necessary to comply with the stormwater permit.
This requirement applies at EDPA for all existing permittees. New permittees have 12 months to
create their SPPP and shall conduct training immediately upon completion. As such, the
requirement for new Tier A permittees is EDPA+12 months.
8. Stormwater Management Design Review Training (Part IV.F.8)
The draft permit renewal retains the stormwater management design review training requirement
that was first introduced in 2018. Specifically, permittees shall ensure that all design engineers,
municipal engineers and other individuals who review the stormwater management designs for
development and redevelopment projects on behalf of the municipality (see Part IV.E.1), complete
the Stormwater Management Design Review Course (see
www.nj.gov/dep/stormwater/training.htm
) once every five years. This course covers the
Stormwater Management rule criteria and the NJ Stormwater BMP Manual. For both designers of
stormwater management facilities and the public officials who review them, implementing the
Stormwater Management rules requires an understanding of both the municipal planning
requirements and the technical standards. The class is intended for those involved in the technical
planning, design, and review process for compliance with the Stormwater Management rules.
The course is taught by Department staff and is held either virtually through an interactive webinar,
or in person in a classroom setting over two or more days, totaling approximately 12 hours.
Attendees can earn Continuing Processional Competency credits (CPCs) upon completion.
Individuals who review stormwater management designs and have not completed this training
within the past five years must attend the next scheduled course offering. If unable to attend a
scheduled course offering, the permittee must notify the Department in writing no later than thirty
days after the missed course offering explaining why attendance was not possible and what
alternate arrangements are being made. The Department will offer this course free of charge, twice
per year.
66
Permittees shall ensure that all individuals that review and approve stormwater management
designs for major development projects on behalf of the permittee for compliance with the
Stormwater Management rules at N.J.A.C. 7:8 et seq. have completed this mandatory Department
provided training.
Existing Tier A permittees shall implement this requirement upon EDPA. New Tier A permittees
shall implement this condition within 12 months of EDPA.
9. Stormwater Management Rule Amendment Training (Part IV.F.9)
This new permit condition requires the same individuals that review and approve stormwater
management designs for major development projects on behalf of the permittee for compliance
with the Stormwater Management rules at N.J.A.C. 7:8 et seq. also complete this mandatory
Department provided training within one year of the adoption of the rule amendments if they are
not due to take the full course again in that same timeframe, if the Department determines that the
amendments warrant training. This ensures that these individuals are educated on the various
ongoing rule amendments within a reasonable amount of time and that their interpretation and
implementation is correct as soon as possible, rather than waiting for years after they were effective,
which could lead to stormwater management designs being reviewed and approved incorrectly
during that time. The course will be taught by Department staff and held either virtually through an
interactive webinar, or in person in a classroom setting. Attendees can earn CPCs upon completion.
The Department will offer this course free of charge.
Existing and new permittees shall implement this condition upon notification by the Department
that this amendment training is needed, which will allow the design review engineers one year to
take the training.
10. Municipal Board and Governing Body Member Related Training (Part IV.F.10)
As per the 2018 Tier A permit, permittees shall ensure that municipal board and governing body
members that review and approve applications for development and redevelopment projects,
complete the Asking the Right Questions in Stormwater Review Training Tool” posted at
www.nj.gov/dep/stormwater/training.htm.
This free online interactive training tool is designed for
Municipal Board and Governing Body members to provide a general understanding of post
construction requirements. This course must be completed by those individuals that review any
projects for compliance with Part IV.F.7 of this permit.
The Municipality is required to maintain a list of the dates and names of training program
participants in its SPPP.
Existing Tier A permittees have already been required to implement this training and therefore
training must be completed by current municipal board and governing body members on or before
EDPA and by new members within six months of commencing duties. Once per term of service
thereafter, municipal board and governing body members must also review at least of one of the
tools offered under Post-Construction Stormwater Management found at the website above.
New permittees shall ensure that their current municipal board and governing body members
complete the training on or before EDPA + 6 months. Additionally, new board members for new
Tier A permittees must complete this training within six months of commencing duties. Once per
term of service thereafter, municipal board and governing body members must also review at least
67
of one of the tools offered under Post-Construction Stormwater Management found at the website
above.
G. Minimum Standards for MS4 Mapping, Stream Scouring, and Illicit Discharge Detection and
Elimination Programs (Part IV.G)
A summary of these components as included in the 2018 Tier A permit is as follows:
Outfall Pipe Mapping Existing permittees were required to develop, update and maintain an
outfall pipe map showing the location of the end of all MS4 outfall pipes (tidal and non-tidal)
owned or operated by the permittee which discharge to a surface water body. The outfall pipe map
was to be submitted to the Department in an electronic format by December 21, 2020;
Stream ScouringExisting permittees were required to develop, update and implement a program
to detect, investigate and control any localized stream scouring from stormwater outfall pipes
owned or operated by the municipality. Permittees were required to, at a minimum, inspect each
outfall pipe which discharges to a stream for localized stream scouring in the vicinity of the outfall
pipe at least once every five years and to inspect any outfall pipes newly identified for localized
stream scouring in the vicinity of the outfall pipe. If scouring was detected, the permittee was
required to document sources of stormwater that contribute to the outfall pipes identified as having
scouring, investigate each identified source of scouring, prioritize, schedule and complete
remediation of identified localized stream scouring and make all stream scouring restoration in
accordance with the Standards for Soil Erosion and Sediment Control in New Jersey at N.J.A.C.
2:90-1.3 (e.g., Conduit Outlet Protection 12-1) and the requirements for bank stabilization and
channel restoration found at N.J.A.C. 7:13-12.14. All associated maintenance or repairs to
stormwater facilities were required to be made in accordance with N.J.A.C. 7:8-5.8.; and
Illicit Discharge Detection and Elimination Illicit Discharge Detection and Elimination (IDDE)
is one of the six Federal Minimum Control Measures (see
www.epa.gov/npdes/stormwater-
discharges-municipal-sources and 40 CFR 122.34(b)(3)) which the 2018 Tier A permit addressed
through requirements under the heading “Minimum Standards for MS4 Outfall Pipe Mapping, and
Illicit Discharge and Scouring Detection and Control.” In the 2018 Tier A permit, permittees were
required to develop, update, implement and enforce an ongoing IDDE Program. This program was
required to be documented in the SPPP. Permittees were required to, at a minimum, conduct visual
dry weather inspection of all outfall pipes owned or operated by the municipality at least once every
five years to determine if dry weather flow or other evidence of illicit discharge is present,
investigate the source if evidence of illicit discharge is found, eliminate non-stormwater discharges
that are traced to their source and found to be illicit connections, document investigations and
actions taken using the Department’s Illicit Connection Inspection Report Form, inspect any outfall
pipes newly identified for illicit discharges, investigate dry weather flows discovered during routine
inspection and maintenance of other elements of the MS4, and investigate, within three months of
receipt, complaints and reports of illicit connections, including those from operating entities of
interconnected MS4s. The 2004 and 2009 permits also contained similar requirements for IDDE.
This permit renewal retains and enhances these requirements with changes to include mapping
requirements for all storm sewer infrastructure, as well as including minimum timeframes for
completion of permit requirements for stream scouring and illicit discharge detection and elimination.
This permit renewal also includes a minor revision to the heading of these requirements to reflect the
enhanced requirements. A summary of the proposed requirements is as follows:
68
1. MS4 Mapping
The permittee shall develop, update, and maintain a MS4 Infrastructure Map that delineates the
location of the following stormwater features that are owned or operated by the permittee,
including their associated attributes noted in parentheses:
o MS4 outfalls (receiving surface water name, type of outfall);
o MS4 ground water discharge points (type);
o MS4 interconnections (type into/from, entity);
o Storm drain inlets (type, catch basin present, label present, retrofitted);
o MS4 manholes;
o MS4 conveyance (type, direction of flow);
o MS4 pump stations;
o Stormwater facilities (type); and
o Property boundaries of maintenance yard(s) and other ancillary operations (type).
The permittee shall ensure that the MS4 Infrastructure map be:
o Reviewed annually, or more frequently as necessary, and updated to include the location
or attributes of any new or newly identified MS4 infrastructure;
o Posted on the permittee’s dedicated stormwater webpage and included as a weblink within
the SPPP;
o Submitted electronically to the Department as a georeferenced shapefile, geodatabase, or
an AutoCAD file (with all other non-applicable data stripped out). If the DEP Mapping
Application (https://www.nj.gov/dep/dwq/msrp_map_aid.htm
) is used, then no submittal
is required as the data is automatically submitted to the Department via the mapping
application; and
o Provided to the Department on or before EDPA + 36 months for existing and new
permittees.
o Existing permittees: This time frame does not extend the deadline of December 21, 2020,
for the submission of the MS4 outfall pipe map.
These enhanced MS4 mapping requirements will expand on the requirements of the 2018 Tier A
permit. Permittees will be required to map their entire storm sewer system including outfalls,
ground water discharge points, interconnections, storm drain inlets, manholes, conveyance, pump
stations, stormwater facilities, and maintenance yard boundaries. This MS4 Infrastructure Map will
be required to be posted on the permittee’s dedicated stormwater webpage. Consistent with the
requirements of the 2018 permit, the Department is requiring that the submission of the MS4 map
69
be in an electronic format.
The deadline for submitting the map is EDPA + 36 months for existing and new Tier A permittees.
As noted in Section 1, Introduction, above, the Department has determined that this enhanced
mapping is necessary to improve the proper operation and maintenance of the storm sewer systems
throughout the state. Mapping of infrastructure is crucial for proper asset management as
permittees must be aware of the location of their storm sewer system components in order to
conduct proper operation and maintenance. Knowing the location of storm sewer system
components is also necessary when implementing a stream scouring and illicit discharge detection
and elimination program.
The Department is continuing to provide a free to use, ArcGIS Online based, stormwater
infrastructure mapping “application or “app”. This application was developed with the intention
of providing a method for municipalities to easily create a detailed map of stormwater
infrastructure. As part of the application development process, the Department acquired a pool of
licenses that are to be distributed to municipalities who are interested in the using the ArcGIS
Online based application. These licenses, which otherwise would cost money for municipalities to
obtain, are being offered free of charge. Municipalities who already have access to an ArcGIS
Online license can be invited to the application using their existing user information and may
continue to use their license to collect stormwater infrastructure data. Permittees can satisfy the
MS4 mapping requirements of this permit by using this application to upload stormwater
infrastructure location information directly to the Department. Permittees can also provide
stormwater infrastructure locational coordinates to the Department in the form of an ESRI
Shapefile, ESRI Geodatabase, AutoCAD DWG, or MS Excel spreadsheet which the Department
can then upload into the application’s data layer. The use of this application for submittal of
stormwater infrastructure mapping data will constitute compliance with the NPDES Electronic
Reporting Rule. Use of this application for collection and submittal of data for newly mapped
stormwater infrastructure would be advantageous, as it will likely prevent duplication of efforts
required to comply with both the permit requirement and the Federal Electronic Reporting
requirement. This application can also be used by permittees in conjunction with facilities
maintenance activities; stream scouring detection and elimination activities; and illicit discharge
detection and control activities, at their convenience.
2. Stream Scouring
The permittee shall develop, update, and implement a program to detect, investigate and control
any localized stream scouring from stormwater outfalls owned or operated by the permittee. This
program shall be described in the SPPP.
The permittee shall, at a minimum:
Inspect each MS4 outfall that discharges to a stream, and the surrounding area in the vicinity
of the MS4 outfall, for localized scouring of the stream banks or bottom caused by the outfall.
Each outfall shall be inspected at least once every five years, with a minimum of 20% of the
total number of outfalls or 100 per year, whichever is greater;
Inspect, within 30 days of identification, any new and/or newly identified outfalls as required
above for localized scouring of the stream banks or bottom caused by the outfall;
70
Investigate, within 30 days of receipt, all complaints and reports of stream scouring;
When localized stream scouring is detected, identify sources of stormwater that contribute to
the scouring from the outfall within 3 months;
Where identified sources are located on property owned or operated by the permittee, corrective
action shall be taken by the permittee to reduce stormwater rate or volume when feasible;
Where identified sources are within the jurisdiction of the permittee, but not located on property
owned or operated by the permittee, the permittee shall ensure that proper operation and
maintenance of stormwater facilities is performed by the entity responsible for the facility;
Prioritize, schedule and complete remediation of identified localized stream scouring as soon
as possible, taking action based upon the requirements above. If not able to be completed within
12 months, a schedule for completion shall be submitted to the MS4 Case Manager before the
12 month deadline. (See https://www.nj.gov/dep/dwq/msrp_managers.htm
). This schedule of
completion shall be maintained with updated information and provided to the MS4 Case
Manager on a quarterly basis until completion;
All stream scouring restoration shall be made in accordance with the Standards for Soil Erosion
and Sediment Control in New Jersey at N.J.A.C. 2:90-1.3 (e.g., Conduit Outlet Protection 12-
1) and the requirements for bank stabilization and channel restoration found at N.J.A.C. 7:13-
12.14;
All associated maintenance or repairs to stormwater facilities shall be made in accordance with
N.J.A.C 7:8-5.8. Any changes to stormwater facilities that were originally approved as part of
a major development project must be reviewed for compliance with N.J.A.C. 7:8 et seq. and
the permittee’s SCO or RSIS, as applicable, by a design review engineer who has completed
the Department’s Stormwater Design Review course; and
Maintain a log and document all investigations and actions taken sufficient to demonstrate
compliance with this requirement. Outfall inspections shall include all information requested
on the Department’s Outfall Inspection Form. Documentation of stream scouring shall include
all of the information requested on the Department’s Stream Scouring Investigation
Recordkeeping Form. (See https://www.nj.gov/dep/dwq/tier_a.htm
). These forms request
information related to the outfall location, date visited, name of inspector, and observations of
the outfall’s structural integrity and if and what maintenance or repairs need to take place, etc.
The Stream Scouring requirements of this permit are included to protect water quality from
negative effects of erosion and have been enhanced to include minimum timeframes for
completion. The Stream Scouring requirements of this permit align the physical inspection of the
outfall pipes with the Illicit Discharge Detection and Control requirements so that the municipality
could do both outfall pipe stream scouring detection and illicit discharge inspection on the same
schedule. As with the 2018 permit, this permit retains references to “localized” stream scouring “in
the vicinity of the outfall pipe.” A definition of “stream scouring” is in Notes and Definitions where
stream scouring means the erosion or removal of streambed or bank material by the physical action
of flowing water and the sediment that it carries. The stream scouring permit conditions require
identification, documentation, investigation and, when feasible, reduction of sources of stormwater
that contribute to outfall pipe stream scouring.
71
Existing Tier A permittees should already have this program in place, so compliance is required at
EDPA. New Tier A permittees must create and implement this program by EDPA + 12 months.
3. Illicit Discharge Detection and Elimination
The permittee shall develop, update, implement and enforce an ongoing Illicit Discharge Detection
and Elimination Program. This program shall be described in the SPPP, as required in Part IV.A.2.
The permittee shall, at a minimum:
Conduct visual dry weather inspection of all outfalls owned or operated by the permittee at
least once every five years, with a minimum of 20% of the total number of outfalls or 100 per
year, whichever is greater, to determine if dry weather flow (flow occurring 72 hours after a
rain event) or other evidence of illicit discharge is present;
Inspect, within 30 days of identification, any new and/or newly identified outfalls, as required
in Part IV.G.1.b.i above, to determine if dry weather flow or other evidence of illicit
connections or discharge is present;
Investigate, within 30 days of identification, dry weather flows or other evidence of illicit
connections or discharge discovered during routine inspection and maintenance of other
elements of the MS4;
Investigate, within 30 days of receipt, complaints and reports of dry weather flows or other
evidence of illicit connections or discharge, including those from operating entities of
interconnected MS4s;
Conduct follow-up investigations, within 30 days of discovering dry weather flows or other
evidence of illicit connections or discharge, to determine the source;
Eliminate as soon as possible, but no later than within one year of discovery, non-stormwater
discharges that are traced to their source and found to be illicit connections or discharges. If
unable to eliminate a non-stormwater discharge within one year, the permittee must request an
extension from the Department no later than thirty days before the end of the one-year
timeframe. If unable to make significant progress at any time during this process, please contact
your case manager. (See https://www.nj.gov/dep/dwq/msrp_managers.htm
); and
Document all investigations and actions taken using the Department’s Illicit Connection
Inspection Report Form. (See https://www.nj.gov/dep/dwq/tier_a.htm
).
The permittee shall adopt and enforce an ordinance that prohibits illicit connections to the MS4
owned or operated by the permittee. (See https://www.nj.gov/dep/dwq/example_ordinance.htm
for
a model ordinance.)
The Illicit Discharge Detection and Control requirements of this permit are enhanced to include
minimum timeframes for completion of permit requirements. These timeframes include:
conducting visual dry weather inspections of all outfalls owned or operated by the permittee once
every five years; inspecting all new and/or newly identified outfalls within 30 days of identification
for dry weather flow; inspecting dry weather flows that were discovered during routine inspections
72
within 30 days of identification; investigating complaints and reports of illicit connections within
30 days of receipt; investigating to discover the source of illicit connection within 30 days; and
eliminating illicit connections within one year of discovery. This is in part due to comments
received by the Department from the EPA on the 2018 Tier A Permit, the 2019 Public Complex
Permit, and the 2020 Highway Agency Permit. The Department has included a link to both the
NJDEP Illicit Connection Inspection Report Form and the USEPA Guidance Document as a useful
resource for the illicit discharge program. As specified in the Notes and Definitions section, “illicit
connection” is defined to mean any physical or non-physical (i.e., leak, flow, or overflow into the
municipal separate storm sewer system) connection to an MS4 that discharges domestic sewage;
non-contact cooling water, process wastewater, or other industrial waste (other than stormwater);
or category of non-stormwater discharges that a permittee for the MS4 identifies as a source or
significant contributor of pollutants pursuant to 40 CFR. 122.34(b)(3)(iii), unless that discharge is
authorized under a NJPDES permit. Finally, the requirement to maintain and enforce an ordinance
prohibiting illicit connections is continued from the 2018 permit.
Existing Tier A permittees should already have this program in place, so compliance is required at
EDPA. New Tier A permittees must create and implement this program by EDPA + 12 months.
H. Watershed Improvement Plan (Part IV.H)
1. Background
The Department conducts and oversees a wide array of ambient monitoring for freshwater (rivers,
streams, lakes), marine waters (bays, oceans) and tidal rivers. This ambient stream monitoring is
conducted and used to regularly assess the ‘health’ of the waters of the state to determine if the
New Jersey Surface Water Quality Standards (NJSWQS) at N.J.A.C. 7:9B et seq. are met and to
assess if designated uses (fishable, swimmable, safe for drinking, etc.) are supported. Monitoring
is conducted for chemical/physical parameters (total suspended solids, phosphorus, nitrate, total
dissolved solids, dissolved oxygen, copper, lead, nickel, zinc, etc.); biological health (e.g., bottom-
dwelling communities, fish populations); phytoplankton (microscopic plants) and sanitary quality
(pathogenic indicators of bacteria and viruses that present a human health risk). One purpose for
ambient monitoring is to evaluate impaired waterways, and that data is required to be compiled and
presented in the biennial Integrated Report. Water quality monitoring networks include sampling
stations in each of the 20 Watershed Management Areas statewide. Waters that do not meet the
applicable standard(s) or support the applicable designated use(s) are considered “impaired” and
are placed on the 303(d) List of Water Quality Limited Waters (also available at
www.nj.gov/dep/wms/bears/assessment.htm
), which is a subpart of theIntegrated Water Quality
Assessment Report.” These impairments are listed in the report based on the subwatershed of the
surface water that the monitoring represents. These subwatersheds are also known as HUC 14s and
are identified by their 14-digit Hydrologic Unit Codes. There are 958 HUC 14s in New Jersey and
they are shown in figure H-1 and H-2 below.
Since 2014, the state has been conducting a rotating regional approach to integrated water quality
assessment as required under the Sections 303(d) and 305(b) of the Federal Clean Water Act. Under
this rotating regional approach, the Department conducts streamlined assessments of statewide
water quality with more comprehensive, detailed assessments conducted in one of the five Water
Regions across the state on a rotating basis every other year. This results in a comprehensive
assessment of the entire state every ten years.
The biennial “Integrated Water Quality Assessment Report”” must include the status of these
subwatersheds, or HUC 14s, in terms of overall water quality and support of designated uses, as
73
well as strategies to maintain and improve water quality. See
https://www.state.nj.us/dep/wms/bears/assessment.htm
and for additional information.
Figure H-1 Figure H-2
Once a HUC 14 is deemed impaired for one or more parameters, Section 303(d) of the Federal
Clean Water Act requires development of a TMDL for the pollutant(s) responsible for each
impairment. A TMDL may be viewed as a pollutant budget for an impaired waterbody, meaning it
is the maximum amount of a pollutant that a waterbody can receive and still meet the NJSWQS.
The regulatory authority for the imposition of TMDLs is found in EPAs Water Quality Planning
and Management Regulations (40 CFR 130.7(c) and (e)), and in New Jersey’s Water Quality
Management Planning rules at N.J.A.C. 7:15-5 et seq.. The TMDL must be calculated so that the
NJSWQS can be attained in consideration of critical conditions and seasonal variation, yet also
include a margin of safety to account for uncertainty. The TMDL is allocated among all the sources
of the pollutant, including MS4 point sources as well as other point sources, nonpoint sources, and
natural contributions. TMDLs include implementation plans which identify a suite of measures
that may assist in reducing loads from each source. Ambient monitoring programs can be used as
a tool to evaluate progress in achieving the objectives of the TMDLs.
2. Addressing TMDLs through the 2018 Tier A MS4 NJPDES Permit
Stormwater point sources, like stormwater nonpoint sources, derive their pollutant loads from land
surface runoff. The distinction is that all point sources from Tier A municipal separate storm sewers
are regulated under the Federal Clean Water Act through the MS4 program. (See 40 CFR.
123.35(b)). These stormwater point sources are addressed through the SBRs, control measures and
74
best management practice requirements contained in the permit. In accordance with 40 CFR
122.34(a) and N.J.A.C. 7:14A-25.6(a)1, best management practices are generally the most
appropriate form of effluent limitations when designed to satisfy technology-based requirements.
The SBRs and other permit conditions that Tier A permittees are required to implement are
designed to reduce pollutant loadings in all watersheds, especially impaired watersheds. In the 2018
permit renewal, the Department stated that for waterbodies with approved or adopted TMDLs, the
reductions associated with compliant implementation of each SBR constituted reasonable progress
toward meeting the reductions specified in the TMDLs. Examples included: adoption and
enforcement of the pet waste disposal ordinance; prohibition of the feeding of unconfined wildlife
on public property; cleaning catch basins; street sweeping; performing good housekeeping at
maintenance yards; and providing related public education and employee training. These basic
requirements provide for a measure of load reduction from existing development. For example,
compliance with the pet disposal ordinance and prohibition of the feeding of unconfined wildlife
on public property will result in lesser quantities of pathogens and nutrients, such as fecal coliform
and Nitrates, being discharged to the waters of the state from the MS4 systems. Likewise,
compliance with street sweeping and catch basin cleaning requirements results in lesser quantities
of solids and any attached pollutants being discharged to the waters of the state from the MS4
systems. Also, compliance with good housekeeping at maintenance yards results in lesser quantities
of pollutants associated with common public works activities (e.g., road salt, and pollutants
associated with vehicle maintenance and vehicle fueling) from being discharged in stormwater
runoff. Finally, public education initiatives improve awareness of the impact that day to day
activities can have on stormwater quality (e.g., pet waste management, litter, landscaping activities
and inappropriate use of storm drains for disposal). Employee training serves to reinforce effective
implementation of the permittees’ MS4 programs.
To supplement the above described SBRs and other permit requirements, to raise awareness of
impaired waterbodies and TMDLs, and to promote municipal strategies to reduce pollutant
discharge from MS4s, the 2018 Tier A permit required permittees to identify pollutants listed in
any approved or adopted TMDLs for waterbodies bordering or within the Tier A Municipality for
inclusion in the SPPP on an annual basis. Additionally, the 2018 Tier A permit required
identification in the SPPP of strategies to address stormwater related pollutants associated with
TMDLs.
Language emphasizing the importance of understanding the conditions and needs of a
municipality’s receiving waters is included in EPA’s Measurable Goals Guidance for Phase II
Small MS4s as follows:
"If you haven't done so already, collect information on your city's receiving waters and what
pollutants and sources are impacting those waters. You should also know the various uses of
your receiving waters so you can design a program to protect those uses. Begin by asking
yourself the following questions: Do you know the names and locations of the waters that
receive a discharge from your MS4? Do you know the character and quality of these waters?
Are any of these waters listed as impaired on your State's 303(d) list? What are the pollutants
impacting these waters? Do you know the designated uses of these waters?"
To e
nsure that this requirement was user friendly and in consideration of limited municipal
resources, the Department developed the TMDL Look-Up Tool (
www.state.nj.us/dep/dwq/msrp-
tmdl-rh.htm). The TMDL Look-Up Tool is an on-line tool to streamline access to TMDL
information and was developed specifically to assist New Jersey’s municipal Stormwater
Coordinators with the identification of this information to use for developing strategies to further
75
reduce the impact of stormwater discharges from MS4s. The TMDL Look-Up Tool uses a
dropdown feature to locate the municipality and county. The tool then displays a list of watersheds
along with a link to any established, approved, or adopted TMDLs associated with any segment of
surface water wholly or partially within or bordering the municipality. TMDLs frequently include
short-term and long-term management strategies within the TMDL along with segment specific
recommendations. Tier A Municipalities have been able to review these strategies and use this
information to assess any local water quality issues in relation to operation and maintenance of the
MS4.
In accordance with 40 CFR 122.34(a)(2), the MS4 requirements should be based on the evaluation
of, among other things, current water quality criteria conditions and permittee compliance. TMDLs
are linked to water quality conditions and must be understood by permittees. Despite this, during
the MS4 stormwater compliance audits, and in preparation of the 2018 Tier A permit renewal, the
Department determined that there was a lack of awareness among municipal representatives
regarding TMDLs in waterbodies within a Tier A Municipality despite their relation to the MS4
system. This may have been partially due to the fact that TMDLs are apportioned by one or more
specific subwatersheds, which do not typically match municipal borders. In fact, multiple TMDLs
can apply within one municipality. The Department attempted to address this gap in awareness in
the 2018 Tier A permit by including the following requirements:
i. The Tier A Municipality was required to annually review approved or adopted TMDL reports
to identify stormwater related pollutants listed therein and associated with any segment of
surface water wholly or partially within or bordering the Tier A Municipality. This
information could be accessed at https://www.nj.gov/dep/dwq/msrp-tmdl-rh.htm
.
ii. The Tier A Municipality was also required to use this TMDL information identified to:
(1) assist in the prioritization of stormwater facility maintenance including schedules for
repairs required at Part IV.B.6.b.iv (Stream Scouring) and Part IV.C.1.a.iv (Stormwater
Facilities Maintenance); and
(2) identify and develop strategies to address specific sources of stormwater related pollutants
contributing to discharges authorized under the permit. Strategies may have included but
were not limited those found in the implementation section of approved or adopted TMDL
reports (for examples see “Total Maximum Daily Load (TMDL) Guidance for Tier A
MS4 Permittees found at www.nj.gov/dep/dwq/msrp-tmdl-rh.htm
);
iii. The Tier A Municipality was required to annually update its SPPP to list information
identified in i and ii, above; and
iv. The Tier A Municipality was required to incorporate any strategies identified in ii(2), above
as an Optional Measure.
In accordance with Part IV.C.1 (Stormwater Facilities Maintenance) and IV.C.2 (TMDL
Information) of the 2018 Tier A permit, municipalities were required to use TMDL information to
prioritize stormwater facility maintenance. For example, permittees should have updated their
SPPPs to note that they performed repairs and other corrective maintenance on stormwater facilities
that discharge to TMDL waterbodies before other stormwater facilities, or they could have targeted
those facilities for more frequent preventative maintenance. Permittees were also required to use
TMDL information when prioritizing or scheduling repairs for stream scouring, as required at Part
IV.B.6.b.iv (Stream Scouring) of the 2018 Tier A permit.
76
In addition to the requirements explained above, permittees were required to identify and develop
strategies to address specific sources of stormwater related pollutants. Permittees could have used
any identified short-term, long-term or segment specific implementation strategies as contained in
the TMDLs to proactively incorporate strategies into their SPPP. Permittees could have also
included strategies as identified in approved restoration plans as well as any strategies developed
as a result of the review of the local municipality needs and local input. The Tier A permittee should
have incorporated any selected implementation strategy as an Optional Measure in the SPPP. These
Optional Measures were required to be identified in the SPPP, but failure to implement an Optional
Measure identified in the SPPP was not to be considered a violation of the NJPDES permit. These
Optional Measures could then be used in conjunction with the requirements to use TMDL
information to prioritize maintenance and repairs to attain reasonable progress toward achieving
the reductions specified in the approved or adopted TMDL. The Department complemented the
information posted with the TMDL Look-Up Tool new guidance entitled “Total Maximum Daily
Load (TMDL) Guidance for Tier A MS4 Permittees” to assist municipalities in evaluating
strategies (see www.nj.gov/dep/dwq/msrp-tmdl-rh.htm
).
3. Addressing TMDL and Impaired Waters through this Tier A MS4 NJPDES Permit Renewal
MS4 stormwater compliance audits were conducted for 37 Tier A permittees (8.1% of Tier A
permittees), which included online reviews of permittees’ online SPPPs, since the 2018 permit
became effective. Despite the requirements in the 2018 permit, most permittees did not include
their TMDLs in their SPPP. Furthermore, they did not explain in their SPPP plans to prioritize
maintenance and repairs in those areas, nor provide any strategies developed to improve water
quality in TMDL affected waters.
Changes in this permit renewal are based on current information and stormwater related concerns,
which includes, but is not limited to: surface water quality impairments as per the final 2018/2020
Integrated Report, adopted/approved Total Maximum Daily Loads (TMDLs), the presence of
Harmful Algal Blooms (HABs), the Surface Water Quality Standard water quality classification
upgrades to N.J.A.C. 7:9B that occurred in May 19, 2003, November 3, 2003, August 2, 2004, June
20, 2005, June 16, 2008, and April 6, 2020, as well as the serious stormwater flooding that has
resulted from recent storm events, including Hurricane Ida.
Further, as many of the surface waters subject to TMDLs and impairments do not have point source
discharges besides the contribution from the MS4 systems, the Department has determined that the
stormwater discharges from MS4s are having a significant impact on water quality throughout the
state.
The Watershed Improvement Plan (“WIP”) is a new requirement in this permit renewal, included
as Part IV, Section H of the proposed permit. The goal in instituting a WIP is to make reasonable
progress towards restoring water quality in the impaired waters of the state, including those waters
with adopted/approved TMDLs. The Department believes the requirement is necessary based on
available water quality data, a more thorough and comprehensive review of other water quality and
quantity concerns as noted in the Introduction section of this Fact Sheet, and in consideration of
the State’s policy (see N.J.A.C. 7:9B et seq.) to restore, maintain and enhance the chemical,
physical and biological integrity of its waters.
The ultimate implementation of this WIP is intended to ensure compliance with the water quality
requirements of the Federal Clean Water Act. A depiction of these waterbodies with TMDLs or
impairments is included Figure H-3. The Department has, therefore, determined that each Tier A
77
permittee must develop a WIP. Each WIP would be tailored to the unique circumstances of the
municipalities and their respective subwatersheds, rather than dictating detailed measures each
permittee must undertake to address the specific TMDLs/Impairments within and bordering the
waterbodies their MS4s discharge into.
The WIP is composed of three phases; the Watershed Inventory Report, Watershed Assessment
Report, and Watershed Improvement Plan Report. Each of these phases have deliverables to the
Department and the requirements are listed out below.
The Watershed Inventory Report is the first phase that is due EDPA +36 months and shall
summarize and include an electronic map of the following items:
All stormwater outfalls owned/operated by the permittee;
The drainage area for each outfall(s);
The receiving waterbodies of those outfalls;
The water quality classification of all receiving waterbody segments;
All stormwater interconnections from the municipality into another entities’ storm or sanitary
sewer system,
The drainage area for each interconnection into another entities’ storm or sanitary sewer
system,
All stormwater connection points into the municipality from another entities’ storm sewer
system,
All storm drain inlets,
Area associated with each TMDL for waters that lie within or bordering the municipality,
Area associated with each water quality impairment for waters that lie within or bordering the
municipality
Overburdened communities,
Impervious areas, and
The Location and ownership of all privately (not/owned/operated) owned stormwater outfalls
and basins/infrastructure
The second phase that is due EDPA + 48 months is the Watershed Assessment Report that must
include but is not limited to:
An assessment of potential water quality improvement projects by subwatershed and
parameter;
An estimate of the percent reduction in loading of the TMDL/impaired parameters due to
project(s) above;
A summary of feedback from public information sessions;
An estimate of funding needs for each project, and identification of potential funding sources,
including the New Jersey Water Bank (NJWB); the formation of an SWU, using, 319 grants,
FEMA BRIC grants; Ag $, etc.; and
An estimate of an implementation schedule.
The permittee also shall post the Watershed Assessment Report, along with an announcement of a
60-day comment period for formal public input on its municipal website.
The third phase that the permittee shall prepare and submit to the Department on or before EDPA
+ 59 months, the final Watershed Improvement Plan Report, which shall include:
78
A summary of proposed locations and load reductions of water quality improvement projects,
both public and private, to be implemented;
A summary of the public comments received, and the changes made to the Final Plan;
A summary of how the projects will be coordinated with other regulatory requirements, such
as:
o flood protection; endangered habitat/species;
o surface & ground drinking water protection;
o climate change/resiliency;
o green infrastructure/SWM requirements;
o wildlife corridors;
o green acres;
o environmental justice;
o Combined Sewer Overflow Long Term Control Plans;
o wetlands;
o riparian buffers;
o forest corridors
o related ongoing projects;
o Pinelands Commission;
o Highlands Council; and
o Delaware River Basin Commission.
The proposed implementation schedule for the water quality improvement projects;
A schedule of the public information sessions to be held;
Problems identified that are outside the jurisdiction of the permittee, if any. These can be related
to pollutant loading due to agricultural properties, or other lands not under the jurisdiction of
the municipality, and opportunities to address them;
Costs, broken down by project and year, the funding opportunities that will be sought; and
This plan shall describe how stormwater related problems in overburdened communities have
been prioritized.
The permittee shall begin to implement the WIP in accordance with the schedule set forth within
the Plan.
The WIP will be updated when necessary, based upon the biennial (every 2 years) review of the
revisions to the impairments of the permittee’s waterbodies as per the Department’s Integrated Report
and newly adopted TMDLs.
79
Figure H-3
This permit renewal allows each permittee 59 months to prepare their WIP, tailored to their water
quality, MS4 circumstances, and resource opportunities. There are three due dates for the three
stages of WIP development:
Phase 1 is designated as the information gathering stage. Existing and new Tier A permittees
must submit the Watershed Inventory Report by EDPA + 36 months.
Phase 2 is the development of a list of potential actions the permittee can choose from for the
final WIP. Existing and new Tier A permittees must submit the Watershed Assessment Report
by EDPA + 48 months.
Phase 3 is the proposed final WIP with the list of potential actions boiled down to the specific
Actions the permittee selected, along with a reasonable implementation schedule. Existing and
new Tier A permittees must submit the Watershed Improvement Plan Report by EDPA + 59
months.
The Department will be available to assist the permittees in this process. Much of the information
required in Phase 1 is already available on the Department’s GIS system and can be provided free
of charge. The list of potential projects should be comprehensive, and the chosen projects must
consider the MS4 percent reductions listed in all pertinent TMDLs. The full percent reductions
noted in the TMDLs do not have to be accounted for in the potential or chosen projects, as some
percent reductions should have already taken place through the implementation of the other permit
80
conditions. However, permittees are expected to develop a WIP that will reasonably reduce the
contribution of applicable pollutants. The WIPs implementation, in concert with other any other
referenced actions, will improve the quality of the stormwater runoff from within their jurisdiction
to, in turn, improve and restore the water quality of the waters of the state to achieve compliance
with the surface water quality standards.
It is understood that the Phase 2 and Phase 3 efforts will largely depend upon the individual
circumstances that lay within each municipality. However, the Department will provide whatever
assistance it has available to assist the permittees in this process. Once Stage 3 of the WIP is
submitted, the Department will review and provide comments as appropriate. It should also be
noted that while each permittee is individually responsible for complying with the requirement to
develop a WIP, the Department encourages municipalities to work together in developing more
regionalized WIPs where a regional approach would be more effective at meeting the surface water
quality standards or would result in accelerated water quality improvements. Regionalized WIPs
will be accepted as compliant with this requirement, as long as each permittee’s responsibilities
under the regional WIP are clearly outlined and agreed upon by the group of permittees covered by
the regional WIP. Further, the Department will prioritize regional WIPs in terms of Department
assistance, funding opportunities, and review and approval.
There is some data available to assist permittees with mapping privately owned stormwater
facilities. The New Jersey Hydrologic Modeling Database (or H&H Database) is posted online and
encompasses several decades of data collected by NJ Soil Conservation Districts and the New
Jersey Department of Agriculture. This database contains a wealth of information regarding
stormwater management basins and data can be downloaded based on location. See
https://hydro.rutgers.edu/ to view the database map or https://hydro.rutgers.edu/public_data/
to
download data in an Excel format. The information in this database may help permittees to identify
stormwater basins in the municipality that they were not aware of. For most stormwater facilities,
the database contains original design plans which may help to identify the maintenance
requirements of a stormwater facility and can help the permittee to develop a more robust inspection
and maintenance plan as a result.
Permittees are encouraged to explore both commercial and public resources for data collection and
management. This could include sharing equipment and resources with other entities, including
other permittees. Other public agencies, such as the New Jersey Highlands Council and County
agencies may already have a database containing information that would be useful to permittees.
Permittees may also be able to obtain stormwater facility locational information already collected
by these and other public organizations.
To assist permittees with the required collection of location information of stormwater facilities,
the Department developed a voluntary, free ArcGIS Online Mapping Tool. This application (app)
allows for permittees to inventory and map stormwater facilities at their convenience. The
Department anticipates that the app will be expanded in the future to allow the user to document
additional information, including records of maintenance actions. When the expanded app is
available, permittees may be able to use the app to demonstrate compliance with the maintenance
requirement in this permit.
While creating an inventory using this application, Tier A permittees are strongly encouraged to
capture additional information about components of the MS4 system in order to optimize operation
and maintenance activities. This information is best managed using an electronic database;
however, as previously stated, it is anticipated that future versions of this app will be expanded to
provide for more detailed information collection. Also, inspection notes, such as facility condition,
81
maintenance activity, date of inspection, evidence of flooding and photographs can be tracked in a
municipal stormwater database. This would be useful to the permittee and its Stormwater
Coordinator for overseeing and prioritizing operation and maintenance of its own infrastructure;
for ensuring proper operation and maintenance of infrastructure not owned or operated by the
municipality; and for collecting and reporting statistical information necessary to complete the
Annual Report required by this draft permit.
I. Optional Measures and Additional Measures (Part IV.I)
1. Optional Measures
Permittees may incorporate Optional Measures into the MS4 stormwater program that extend
beyond the requirements of the permit to further prevent or reduce pollution to waters of the State.
Optional Measures are typically BMPs or control measures that are developed by the Tier A
permittee at its own discretion. The objective of Optional Measures is to encourage municipalities
to be proactive and creative in implementing strategies to bolster their MS4 stormwater program.
Optional Measures are required to be identified in the SPPP but failure to implement an Optional
Measure identified in the SPPP shall not be considered a violation of this NJPDES permit. See also
N.J.A.C. 7:14A-25.6(a) and (i). The 2018 Tier A MS4 Permit included a Refuse
Container/Dumpster Ordinance as a potential Optional Measure in permit section IV.E.2. This
permit renewal also includes this as an optional ordinance (renamed as Optional
Container/Dumpster Ordinance) in the Community-wide Ordinance permit Section IV.F.ix.
2. Additional Measures
The requirements for Additional Measures are retained from the 2018 Tier A MS4 permit and were
also included in the 2018 Tier B MS4 permit. Additional Measures are non-numeric (e.g., best
management practices) or numeric effluent limitations that are expressly required to be included in
a municipality’s MS4 stormwater program by a TMDL, a regional stormwater management plan,
other elements of an adopted areawide Water Quality Management Plan, or the adopted Statewide
Water Quality Management Plan. Additional Measures are allowable pursuant to N.J.A.C. 7:14A-
25.6(a) and (e).
Additional Measures are not required for any municipality at this time. In the event that the
Department determines that Additional Measures are appropriate, the Department will provide
written notice of the adoption of any Additional Measures to any affected municipality. The
Department will list each adopted Additional Measure in a minor modification to the permit since
the adoption process of the underlying plan (i.e., TMDL; regional stormwater management plan;
other elements of an adopted areawide Water Quality Management Plan; or adopted Statewide
Water Quality Management Plan) will have already provided opportunity for public comment. For
any required Additional Measures other than numeric effluent limitations, the required Additional
Measures will specify, according to the underlying plan, the best management practices that shall
be implemented, measurable goals and an implementation schedule.
J. Recordkeeping (Part IV.J)
The permittee shall retain copies of all records required to be kept by this permit. Records must be
available to the Department upon request. This permit requirement remains unchanged from both the
2018 Tier A and Tier B MS4 permits, therefore must be implemented for both existing and new Tier A
permittees at EDPA.
82
K.
Annual Report and Certification (Part IV.K)
Per the 2018 Tier A and Tier B MS4 permits, permittees were required to submit an Annual Report
and Certification and Supplemental Questionnaire summarizing the status of compliance with the
conditions of this permit using the electronic format provided by the Department via the MSRP Annual
Report service accessed through the Regulatory Services Portal (https://nj.gov/dep/online/
). T
his
permit renewal retains this requirement for all Tier A permittees to continue to submit the Annual
Report and Certification and Supplemental Questionnaire, uploaded as an attachment to the Annual
Report. These reports are due for submission by May 1 annually and shall summarize the status of
compliance with the permit conditions for the subject year between January 1 and December 31. The
permittee’s Stormwater Program Coordinator is responsible for electronically certifying, signing, and
dating the Annual Report.
Th
e permittee shall retain any records necessary to demonstrate compliance on-site for a period of at
least five years.
Both existing and new Tier A permittees must comply with this condition at EDPA.
As noted in Part II.B.3, Tier A Municipalities are required to comply with the NPDES Electronic Reporting
rule at 40 CFR Part 127. As noted at Part II.B.3, this Federal rule requires electronic submission of General
Permit Authorization requests (i.e., RFAs); general permit termination/revocation requests; and MS4
program reports by December 21, 2025. Since submission of the Annual Report occurs electronically as
required in Part IV.K, the requirements of this rule are satisfied with respect to Annual Reports prior to the
2025 deadline.
