A.
Scope and purpose.
(1)
Policy statement. Flood control, groundwater recharge, and pollutant
reduction shall be achieved through the use of stormwater management
measures, including green infrastructure best management practices
(GI BMPs) and nonstructural stormwater management strategies. GI BMPs
and low-impact development (LID) should be utilized to meet the goal
of maintaining natural hydrology to reduce stormwater runoff volume,
reduce erosion, encourage infiltration and groundwater recharge, and
reduce pollution. GI BMPs and LID should be developed based upon physical
site conditions and the origin, nature and the anticipated quantity,
or amount, of potential pollutants. Multiple stormwater management
BMPs may be necessary to achieve the established performance standards
for water quality, quantity, and groundwater recharge.
(2)
Purpose. The purpose of this section is to establish minimum stormwater management requirements and controls for "major development," as defined below in Subsection B.
(3)
(4)
Compatibility with other permit and ordinance requirements.
(a)
Development approvals issued pursuant to this section are to
be considered an integral part of development approvals and do not
relieve the applicant of the responsibility to secure required permits
or approvals for activities regulated by any other applicable code,
rule, act, or ordinance. In their interpretation and application,
the provisions of this section shall be held to be the minimum requirements
for the promotion of the public health, safety, and general welfare.
(b)
This section is not intended to interfere with, abrogate, or
annul any other ordinances, rule or regulation, statute, or other
provision of law except that, where any provision of this section
imposes restrictions different from those imposed by any other ordinance,
rule or regulation, or other provision of law, the more restrictive
provisions or higher standards shall control.

C.
Design and performance standards for stormwater management measures.
(1)
Stormwater management measures for major development shall be
designed to provide erosion control, groundwater recharge, stormwater
runoff quantity control, and stormwater runoff quality treatment as
follows:
(a)
The minimum standards for erosion control are those established
under the Soil and Sediment Control Act, N.J.S.A. 4:24-39 et seq.,
and implementing rules at N.J.A.C. 2:90.
(b)
The minimum standards for groundwater recharge, stormwater quality,
and stormwater runoff quantity shall be met by incorporating green
infrastructure.
(2)
The standards in this section apply only to new major development
and are intended to minimize the impact of stormwater runoff on water
quality and water quantity in receiving water bodies and maintain
groundwater recharge. The standards do not apply to new major development
to the extent that alternative design and performance standards are
applicable under a regional stormwater management plan or Water Quality
Management Plan adopted in accordance with Department rules.
(a)
Alternative standards shall provide at least as much protection
from stormwater-related loss of groundwater recharge, stormwater quantity
and water quality impacts of major development projects as would be
provided under the standards in N.J.A.C. 7:8-5.
D.
Stormwater management requirements for major development.
(1)
The development shall incorporate a maintenance plan for the
stormwater management measures incorporated into the design of a major
development in accordance with the provisions contained in the stormwater
management regulations and herein.
(2)
Stormwater management measures shall avoid adverse impacts of
concentrated flow on habitat for threatened and endangered species
as documented in the Department's Landscape Project or Natural Heritage
Database established under N.J.S.A. 13:1B-15.147 through 15.150, particularly
Helonias bullata (swamp pink) and/or Clemmys muhlenbergii (bog turtle).
(3)
The following linear development projects are exempt from the groundwater recharge, stormwater runoff quality, and stormwater runoff quantity requirements of Subsection D(16), (17) and (18):
(a)
The construction of an underground utility line provided that
the disturbed areas are revegetated upon completion;
(b)
The construction of an aboveground utility line provided that
the existing conditions are maintained to the maximum extent practicable;
and
(c)
The construction of a public pedestrian access, such as a sidewalk
or trail with a maximum width of 14 feet, provided that the access
is made of permeable material.
(4)
A waiver from strict compliance from the green infrastructure, groundwater recharge, stormwater runoff quality, and stormwater runoff quantity requirements of Subsection D(15), (16), (17) and (18) may be obtained for the enlargement of an existing public roadway or railroad; or the construction or enlargement of a public pedestrian access, provided that the following conditions are met:
(a)
The applicant demonstrates that there is a public need for the
project that cannot be accomplished by any other means;
(d)
The applicant demonstrates that it does not own or have other rights to areas, including the potential to obtain through condemnation lands not falling under Subsection D(4)(c) above within the upstream drainage area of the receiving stream, that would provide additional opportunities to mitigate the requirements of Subsection D(15), (16), (17) and (18) that were not achievable onsite.
(5)
Tables 1 through 3 below summarize the ability of stormwater best management practices identified and described in the New Jersey Stormwater Best Management Practices Manual to satisfy the green infrastructure, groundwater recharge, stormwater runoff quality and stormwater runoff quantity standards specified in Subsection D(15), (16), (17) and (18). When designed in accordance with the most current version of the New Jersey Stormwater Best Management Practices Manual, the stormwater management measures found at N.J.A.C. 7:8-5.2 (f) Tables 5-1, 5-2 and 5-3 and listed below in Tables 1, 2 and 3 are presumed to be capable of providing stormwater controls for the design and performance standards as outlined in the tables below. Upon amendments of the New Jersey Stormwater Best Management Practices to reflect additions or deletions of BMPs meeting these standards, or changes in the presumed performance of BMPs designed in accordance with the New Jersey Stormwater BMP Manual, the Department shall publish in the New Jersey Registers a notice of administrative change revising the applicable table. The most current version of the BMP Manual can be found on the Department's website at: https://njstormwater.org/bmp_manual2.htm.
(6)
Where the BMP tables in the NJ Stormwater Management Rule are
different due to updates or amendments with the tables in this section,
the BMP Tables in the Stormwater Management rule at N.J.A.C. 7:8-5.2(f)
shall take precedence.

(7)
An alternative stormwater management measure, alternative removal rate, and/or alternative method to calculate the removal rate may be used if the design engineer demonstrates the capability of the proposed alternative stormwater management measure and/or the validity of the alternative rate or method to the municipality. A copy of any approved alternative stormwater management measure, alternative removal rate, and/or alternative method to calculate the removal rate shall be provided to the Department in accordance with Subsection F(2). Alternative stormwater management measures may be used to satisfy the requirements at Subsection D(15) only if the measures meet the definition of green infrastructure at Subsection B. Alternative stormwater management measures that function in a similar manner to a BMP listed at Subsection D(15)(b) are subject to the contributory drainage area limitation specified at Subsection D(15)(b) for that similarly functioning BMP. Alternative stormwater management measures approved in accordance with this subsection that do not function in a similar manner to any BMP listed at Subsection D(15)(b) shall have a contributory drainage area less than or equal to 2.5 acres, except for alternative stormwater management measures that function similarly to cisterns, grass swales, green roofs, standard constructed wetlands, vegetative filter strips, and wet ponds, which are not subject to a contributory drainage area limitation. Alternative measures that function similarly to standard constructed wetlands or wet ponds shall not be used for compliance with the stormwater runoff quality standard unless a variance in accordance with N.J.A.C. 7:8-4.6 or a waiver from strict compliance in accordance with Subsection D(4) is granted from Subsection D(15).
(8)
Whenever the stormwater management design includes one or more
BMPs that will infiltrate stormwater into subsoil, the design engineer
shall assess the hydraulic impact on the groundwater table and design
the site so as to avoid adverse hydraulic impacts. Potential adverse
hydraulic impacts include, but are not limited to, exacerbating a
naturally or seasonally high water table, so as to cause surficial
ponding, flooding of basements, or interference with the proper operation
of subsurface sewage disposal systems or other subsurface structures
within the zone of influence of the groundwater mound, or interference
with the proper functioning of the stormwater management measure itself.
(9)
Design standards for stormwater management measures are as follows:
(a)
Stormwater management measures shall be designed to take into
account the existing site conditions, including, but not limited to,
environmentally critical areas; wetlands; flood-prone areas; slopes;
depth to seasonal high water table; soil type, permeability, and texture;
drainage area and drainage patterns; and the presence of solution-prone
carbonate rocks (limestone);
(b)

(d)
If a variance in accordance with N.J.A.C. 7:8-4.6 or a waiver from strict compliance in accordance with Subsection D(4) is granted from the requirements of this subsection, then BMPs from Table 1, 2, or 3, and/or an alternative stormwater management measure approved in accordance with Subsection D(7) may be used to meet the groundwater recharge, stormwater runoff quality, and stormwater runoff quantity standards at Subsection D(16), (17) and (18).
(e)
For separate or combined storm sewer improvement projects, such as sewer separation, undertaken by a government agency or public utility (for example, a sewerage company), the requirements of this subsection shall only apply to areas owned in fee simple by the government agency or utility, and areas within a right-of-way or easement held or controlled by the government agency or utility; the entity shall not be required to obtain additional property or property rights to fully satisfy the requirements of this subsection. Regardless of the amount of area of a separate or combined storm sewer improvement project subject to the green infrastructure requirements of this subsection, each project shall fully comply with the applicable groundwater recharge, stormwater runoff quality control, and stormwater runoff quantity standards at Subsection D(16), (17) and (18), unless the project is granted a waiver from strict compliance in accordance with Subsection D(4).
(16)
Groundwater recharge standards.
(a)
This subsection contains the minimum design and performance
standards for groundwater recharge.
(b)
The design engineer shall, using the assumptions and factors for stormwater runoff and groundwater recharge calculations at Subsection E, either:
[1]
Demonstrate through hydrologic and hydraulic analysis
that the site and its stormwater management measures maintain 100%
of the average annual pre-construction groundwater recharge volume
for the site; or
[2]
Demonstrate through hydrologic and hydraulic analysis
that the increase of stormwater runoff volume from pre-construction
to post-construction for the two-year storm is infiltrated.
(c)
This groundwater recharge requirement does not apply to projects within the "urban redevelopment area," or to projects subject to Subsection (16)(d) below.
(d)
The following types of stormwater shall not be recharged:
[1]
Stormwater from areas of high pollutant loading.
High pollutant loading areas are areas in industrial and commercial
developments where solvents and/or petroleum products are loaded/unloaded,
stored, or applied, areas where pesticides are loaded/unloaded or
stored; areas where hazardous materials are expected to be present
in greater than "reportable quantities" as defined by the United States
Environmental Protection Agency (EPA) at 40 CFR 302.4; areas where
recharge would be inconsistent with Department-approved remedial action
work plan or landfill closure plan and areas with high risks for spills
of toxic materials, such as gas stations and vehicle maintenance facilities;
and
[2]
Industrial stormwater exposed to source material.
"Source material" means any material(s) or machinery, located at an
industrial facility, that is directly or indirectly related to process,
manufacturing or other industrial activities, which could be a source
of pollutants in any industrial stormwater discharge to groundwater.
Source materials include, but are not limited to, raw materials; intermediate
products; final products; waste materials; by-products; industrial
machinery and fuels, and lubricants, solvents, and detergents that
are related to process, manufacturing, or other industrial activities
that are exposed to stormwater.
(17)
Stormwater runoff quality standards.
(a)
This subsection contains the minimum design and performance
standards to control stormwater runoff quality impacts of major development.
Stormwater runoff quality standards are applicable when the major
development results in an increase of one-quarter acre or more of
regulated motor vehicle surface.
(b)
Stormwater management measures shall be designed to reduce the
post-construction load of total suspended solids (TSS) in stormwater
runoff generated from the water quality design storm as follows:
[1]
Eighty percent TSS removal of the anticipated load,
expressed as an annual average, shall be achieved for the stormwater
runoff from the net increase of motor vehicle surface.
[2]
If the surface is considered regulated motor vehicle
surface because the water quality treatment for an area of motor vehicle
surface that is currently receiving water quality treatment either
by vegetation or soil, by an existing stormwater management measure,
or by treatment at a wastewater treatment plant is to be modified
or removed, the project shall maintain or increase the existing TSS
removal of the anticipated load expressed as an annual average.
(c)
The requirement to reduce TSS does not apply to any stormwater runoff in a discharge regulated under a numeric effluent limitation for TSS imposed under the New Jersey Pollutant Discharge Elimination System (NJPDES) rules, N.J.A.C. 7:14A, or in a discharge specifically exempt under a NJPDES permit from this requirement. Every major development, including any that discharge into a combined sewer system, shall comply with Subsection D(17)(b) above, unless the major development is itself subject to a NJPDES permit with a numeric effluent limitation for TSS or the NJPDES permit to which the major development is subject exempts the development from a numeric effluent limitation for TSS.
(d)
The water quality design storm is 1.25 inches of rainfall in
two hours. Water quality calculations shall take into account the
distribution of rain from the water quality design storm, as reflected
in Table 4, below. The calculation of the volume of runoff may take
into account the implementation of stormwater management measures.

If more than one BMP in series is necessary to achieve the required
eighty-percent TSS reduction for a site, the applicant shall utilize
the following formula to calculate TSS reduction:
|
R = A + B - (A x B)/100
|
|
Where
|
|
R = total TSS Percent Load Removal from application
of both BMPs
|
|
A = the TSS Percent Removal Rate applicable to the
first BMP
|
|
B = the TSS Percent Removal Rate applicable to the
second BMP
|
(f)
Stormwater management measures shall also be designed to reduce,
to the maximum extent feasible, the post-construction nutrient load
of the anticipated load from the developed site in stormwater runoff
generated from the water quality design storm. In achieving reduction
of nutrients to the maximum extent feasible, the design of the site
shall include green infrastructure BMPs that optimize nutrient removal
while still achieving the performance standards in Section IV.P, Q
and R.
(g)
In accordance with the definition of "FW1" at N.J.A.C. 7:9B-1.4,
stormwater management measures shall be designed to prevent any increase
in stormwater runoff to waters classified as FW1.
(h)
The Flood Hazard Area Control Act Rules at N.J.A.C. 7:13-4.1(c)1
establish 300-foot riparian zones along Category One waters, as designated
in the Surface Water Quality Standards at N.J.A.C. 7:9B, and certain
upstream tributaries to Category One waters. A person shall not undertake
a major development that is located within or discharges into a 300-foot
riparian zone without prior authorization from the Department under
N.J.A.C. 7:13.
(i)
Pursuant to the Flood Hazard Area Control Act Rules at N.J.A.C.
7:13-11.2(j)3.i, runoff from the water quality design storm that is
discharged within a 300-foot riparian zone shall be treated in accordance
with this subsection to reduce the post-construction load of total
suspended solids by 95% of the anticipated load from the developed
site, expressed as an annual average.
(j)
This stormwater runoff quality standards do not apply to the
construction of one individual single-family dwelling, provided that
it is not part of a larger development or subdivision that has received
preliminary or final site plan approval prior to December 3, 2018,
and that the motor vehicle surfaces are made of permeable material(s)
such as gravel, dirt, and/or shells.
(18)
Stormwater runoff quantity standards.
(a)
This subsection contains the minimum design and performance
standards to control stormwater runoff quantity impacts of major development.
(b)
In order to control stormwater runoff quantity impacts, the design engineer shall, using the assumptions and factors for stormwater runoff calculations at Subsection E, complete one of the following:
[1]
Demonstrate through hydrologic and hydraulic analysis
that for stormwater leaving the site, post-construction runoff hydrographs
for the two-, ten-, and 100-year storm events do not exceed, at any
point in time, the pre-construction runoff hydrographs for the same
storm events;
[2]
Demonstrate through hydrologic and hydraulic analysis
that there is no increase, as compared to the pre-construction condition,
in the peak runoff rates of stormwater leaving the site for the two-,
ten- and 100-year storm events and that the increased volume or change
in timing of stormwater runoff will not increase flood damage at or
downstream of the site. This analysis shall include the analysis of
impacts of existing land uses and projected land uses assuming full
development under existing zoning and land use ordinances in the drainage
area;
[3]
Design stormwater management measures so that the
post-construction peak runoff rates for the two-, ten- and 100-year
storm events are 50%, 75% and 80%, respectively, of the pre-construction
peak runoff rates. The percentages apply only to the post-construction
stormwater runoff that is attributable to the portion of the site
on which the proposed development or project is to be constructed;
or
[4]
In tidal flood hazard areas, stormwater runoff
quantity analysis in accordance with Subsection 18(6)(a), (b) and
(c) above is required unless the design engineer demonstrates through
hydrologic and hydraulic analysis that the increased volume, change
in timing, or increased rate of the stormwater runoff, or any combination
of the three will not result in additional flood damage below the
point of discharge of the major development. No analysis is required
if the stormwater is discharged directly into any ocean, bay, inlet,
or the reach of any watercourse between its confluence with an ocean,
bay, or inlet and downstream of the first water control structure.
(c)
The stormwater runoff quantity standards shall be applied at
the site's boundary to each abutting lot, roadway, watercourse, or
receiving storm sewer system.
E.
Calculation of stormwater runoff and groundwater recharge:
(1)
Stormwater runoff shall be calculated in accordance with the
following:
(a)
The design engineer shall calculate runoff using one of the
following methods:
[1]
The USDA Natural Resources Conservation Service (NRCS) methodology, including the NRCS Runoff Equation and Dimensionless Unit Hydrograph, as described in Chapters 7, 9, 10, 15 and 16 Part 630, Hydrology National Engineering Handbook, incorporated herein by reference as amended and supplemented. This methodology is additionally described in Technical Release 55, Urban Hydrology for Small Watersheds (TR-55), dated June 1986, incorporated herein by reference as amended and supplemented. Information regarding the methodology is available from the Natural Resources Conservation Service website at https://www.nrcs.usda.gov/Internet/FSE_DOCUMENTS/stelprdb1044171.pdf or at United States Department of Agriculture Natural Resources Conservation Service, 220 Davison Avenue, Somerset, New Jersey 08873; or
[2]
The Rational Method for peak flow and the Modified
Rational Method for hydrograph computations. The rational and modified
rational methods are described in "Appendix A-9 Modified Rational
Method" in the Standards for Soil Erosion and Sediment Control in
New Jersey, January 2014. This document is available from the State
Soil Conservation Committee or any of the Soil Conservation Districts
listed at N.J.A.C. 2:90-1.3(a)3. The location, address, and telephone
number for each Soil Conservation District is available from the State
Soil Conservation Committee, PO Box 330, Trenton, New Jersey 08625.
The document is also available at: http://www.nj.gov/agriculture/divisions/anr/pdf/2014NJSoilErosionControlStandardsComplete.pdf.
(b)
For the purpose of calculating runoff coefficients and groundwater recharge, there is a presumption that the pre-construction condition of a site or portion thereof is a wooded land use with good hydrologic condition. The term "runoff coefficient" applies to both the NRCS methodology above at Subsection E(1)(a)[1] and the Rational and Modified Rational Methods at Subsection E(1)(a)[2]. A runoff coefficient or a groundwater recharge land cover for an existing condition may be used on all or a portion of the site if the design engineer verifies that the hydrologic condition has existed on the site or portion of the site for at least five years without interruption prior to the time of application. If more than one land cover has existed on the site during the five years immediately prior to the time of application, the land cover with the lowest runoff potential shall be used for the computations. In addition, there is the presumption that the site is in good hydrologic condition (if the land use type is pasture, lawn, or park), with good cover (if the land use type is woods), or with good hydrologic condition and conservation treatment (if the land use type is cultivation).
(c)
In computing pre-construction stormwater runoff, the design
engineer shall account for all significant land features and structures,
such as ponds, wetlands, depressions, hedgerows, or culverts, that
may reduce pre-construction stormwater runoff rates and volumes.
(d)
In computing stormwater runoff from all design storms, the design
engineer shall consider the relative stormwater runoff rates and/or
volumes of pervious and impervious surfaces separately to accurately
compute the rates and volume of stormwater runoff from the site. To
calculate runoff from unconnected impervious cover, urban impervious
area modifications as described in the NRCS Technical Release 55,
Urban Hydrology for Small Watersheds or other methods may be employed.
(e)
If the invert of the outlet structure of a stormwater management
measure is below the flood hazard design flood elevation as defined
at N.J.A.C. 7:13, the design engineer shall take into account the
effects of tailwater in the design of structural stormwater management
measures.
(2)
Groundwater recharge may be calculated in accordance with the
following: The New Jersey Geological Survey Report GSR-32, A Method
for Evaluating Groundwater-Recharge Areas in New Jersey, incorporated
herein by reference as amended and supplemented. Information regarding
the methodology is available from the New Jersey Stormwater Best Management
Practices Manual; at the New Jersey Geological Survey website at https://www.nj.gov/dep/njgs/pricelst/gsreport/gsr32.pdf,

This section sets forth requirements to protect public safety
through the proper design and operation of stormwater management BMPs.
This section applies to any new stormwater management BMP.
(2)
The provisions of this section are not intended to preempt more stringent municipal or county safety requirements for new or existing stormwater management BMPs. Municipal and county stormwater management plans and ordinances may, pursuant to their authority, require existing stormwater management BMPs to be retrofitted to meet one or more of the safety standards in Subsection H(3)(a), (b) and (c) for trash racks, overflow grates, and escape provisions at outlet structures.
(3)
Requirements for trash racks, overflow grates and escape provisions.
(a)
A trash rack is a device designed to catch trash and debris
and prevent the clogging of outlet structures. Trash racks shall be
installed at the intake to the outlet from the stormwater management
BMP to ensure proper functioning of the BMP outlets in accordance
with the following:
[1]
The trash rack shall have parallel bars, with no
greater than six-inch spacing between the bars;
[2]
The trash rack shall be designed so as not to adversely
affect the hydraulic performance of the outlet pipe or structure;
[3]
The average velocity of flow through a clean trash
rack is not to exceed 2.5 feet per second under the full range of
stage and discharge. Velocity is to be computed on the basis of the
net area of opening through the rack; and
[4]
The trash rack shall be constructed of rigid, durable,
and corrosion-resistant material and designed to withstand a perpendicular
live loading of 300 pounds per square foot.
(b)
An overflow grate is designed to prevent obstruction of the

Definitions. For the purpose of this section, the following terms,
phrases, words and their derivations shall have the meanings stated
herein unless their use in the text of this section clearly demonstrates
a different meaning. When consistent with the context, words used
in the present tense include the future, words used in the plural
number include the singular number, and words used in the singular
number include the plural number. The word " shall" is always mandatory
and not merely directory.
Any granular or solid material such as melting salt or any
other granular solid that assists in the melting of snow.
A surface that has been covered with a layer of material
so that it is highly resistant to infiltration by water.
A permanent building or permanent structure that is anchored
to a permanent foundation with an impermeable floor, and that is completely
roofed and walled (new structures require a door or other means of
sealing the access way from wind driven rainfall). A fabric frame
structure is a permanent structure if it meets the following specifications:
(1) Concrete blocks, jersey barriers or other similar material shall
be placed around the interior of the structure to protect the side
walls during loading and unloading of de-icing materials; (2) The
design shall prevent stormwater run- on and run through, and the fabric
cannot leak., (3) The structure shall be erected on an impermeable
slab; (4) The structure cannot be open sided; and (5) The structure
shall have a roll up door or other means of sealing the access way
from wind driven rainfall.
Any individual, corporation, company, partnership, firm,
association, or political subdivision of this State subject to municipal
jurisdiction.

C.
Deicing material storage requirements.
(1)
Temporary outdoor storage of de-icing materials in accordance
with the requirements below is allowed between October 15th and April
15th:
(a)
Loose materials shall be placed on a flat, impervious surface
in a manner that prevents stormwater run-through;
(b)
Loose materials shall be placed at least 50 feet from surface
water bodies, storm drain inlets, ditches and/or other stormwater
conveyance channels;
(c)
Loose materials shall be maintained in a cone-shaped storage
pile. If loading or unloading activities alter the cone-shape during
daily activities, tracked materials shall be swept back into the storage
pile, and the storage pile shall be reshaped into a cone after use;
(d)
Loose materials shall be covered as follows:
[1]
The cover shall be waterproof, impermeable, and
flexible;
[2]
The cover shall extend to the base of the pile(s);
[3]
The cover shall be free from holes or tears;
[4]
The cover shall be secured and weighed down around
the perimeter to prevent removal by wind; and
[5]
Weight shall be placed on the cover(s) in such
a way that minimizes the potential of exposure as materials shift
and runoff flows down to the base of the pile.
[a]
Sandbags lashed together with rope or cable and
placed uniformly over the flexible cover, or poly-cord nets provide
a suitable method. Items that can potentially hold water (e.g., old
tires) shall not be used.
(e)
Containers must be sealed when not in use; and
(f)
The site shall be free of all de-icing materials between April
16th and October 14th.
(2)
De-icing materials should be stored in a permanent structure
if a suitable storage structure is available. For storage of loose
de-icing materials in a permanent structure, such storage may be permanent,
and thus not restricted to October 15 - April 15.
(3)
The property owner, or owner of the de- icing materials if different,
shall designate a person(s) responsible for operations at the site
where these materials are stored outdoors, and who shall document
that weekly inspections are conducted to ensure that the conditions
of this section are met. Inspection records shall be kept on site
and made available to the municipality upon request.
(a)
Residents who operate businesses from their homes that utilize
de-icing materials are required to perform weekly inspections.
D.
Exemptions.
Residents may store de-icing materials outside in a solid-walled, closed container that prevents precipitation from entering and exiting the container, and which prevents the de-icing materials from leaking or spilling out. Under these circumstances, weekly inspections are not necessary, but repair or replacement of damaged or inadequate containers shall occur within two weeks. If containerized (in bags or buckets) de-icing materials are stored within a permanent structure, they are not subject to the storage and inspection requirements in subsection C above. Piles of de-icing materials are not exempt, even if stored in a permanent structure. This section does not apply to facilities where the stormwater discharges from de-icing material storage activities are regulated under another NJPDES permit.
E.
Enforcement. This section shall be enforced by the Police Department
and/or Code Enforcement of the Township of Monroe during the course
of ordinary enforcement duties.
F.
Violations and penalties.
Any person(s) who is found to be in violation of the provisions
of this section shall have 72 hours to complete corrective action.
Repeat violations and/or failure to complete corrective action shall
result in fines.
Any person(s) who erects, constructs, alters, repairs, converts,
maintains, or uses any building, structure or land in violation of
this section may be subject to penalties as permitted by the Code
of the Township of Monroe.
