General.

(a)

All major development shall comply with the design and performance standards for erosion control, groundwater recharge, stormwater runoff quantity control, maintenance and other requirements contained in this subsection.

(b)

In addition to all other applicable requirements, major development that results in an additional 1/4 acre of total impervious surface on a development site shall comply with the standards for stormwater runoff quality control.

(c)

To the maximum extent practicable, these standards shall be met by incorporating nonstructural stormwater management strategies into the design. Nonstructural strategies include both environmentally sensitive site design and source controls that prevent pollutants from being placed on the site or from being exposed to stormwater. If these strategies alone are not sufficient to meet these standards, structural stormwater management measures necessary to meet these standards shall be incorporated into the design.

(d)

Structural BMPs should be integrated with nonstructural stormwater management strategies and proper maintenance plans.

(e)

Source control plans should be developed based upon physical site conditions and the origin, nature, and the anticipated quantity or amount of potential pollutants.

(f)

Multiple stormwater management BMPs may be necessary to achieve the established performance standards for water quality, quantity, and groundwater recharge.

(g)

Development applications and approvals shall incorporate a maintenance plan for the stormwater management measures incorporated into the design of the development in accordance with § 190-83D(8).

(h)

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 muhlnebergi (bog turtle).

(2)

Nonstructural stormwater management strategies.

(a)

Strategy prioritization. To the maximum extent practicable, the standards in § 190-83D(3) through (7) shall be met by incorporating nonstructural stormwater management strategies set forth in this § 190-83D(2) into the design. The applicant shall identify the nonstructural measures incorporated into the design of the project. If the applicant contends that it is not feasible for engineering, environmental, or safety reasons to incorporate any nonstructural stormwater management measures identified in Subsection D(2)(b) below into the design of a particular project, the applicant shall identify the strategy considered and provide a basis for the contention.

(b)

Strategy objectives. Nonstructural stormwater management strategies incorporated into site design shall:

[1]

Protect areas that provide water quality benefits or areas particularly susceptible to erosion and sediment loss;

[2]

Minimize impervious surfaces and break up or disconnect the flow of runoff over impervious surfaces;

[3]

Maximize the protection of natural drainage features and vegetation;

[4]

Minimize the decrease in the "time of concentration" from preconstruction to postconstruction. "Time of concentration" is defined as the time it takes for runoff to travel from the hydraulically most distant point of the watershed to the point of interest within a watershed;

[5]

Minimize land disturbance including clearing and grading;

[6]

Minimize soil compaction;

[7]

Provide low-maintenance landscaping that encourages retention and planting of native vegetation and minimizes the use of lawns, fertilizers and pesticides;

[8]

Provide vegetated open-channel conveyance systems discharging into and through stable vegetated areas;

[9]

Provide other source controls to prevent or minimize the use or exposure of pollutants at the site, in order to prevent or minimize the release of those pollutants into stormwater runoff. Such source controls include, but are not limited to:

[a]

Site design features that help to prevent accumulation of trash and debris in drainage systems, including features that satisfy § 190-83D(7)(c);

[b]

Site design features that help to prevent discharge of trash and debris from drainage systems;

[c]

Site design features that help to prevent and/or contain spills or other harmful accumulations of pollutants at industrial or commercial developments;

[d]

(c)

Perpetual maintenance. Any land area used as a nonstructural stormwater management measure to meet the performance standards in § 190-83D(3) through (6) shall be dedicated to a government agency, subjected to a conservation restriction filed with the appropriate County Clerk's office, or subject to an approved equivalent restriction that ensures that measure or an equivalent stormwater management measure approved by the reviewing agency is maintained in perpetuity.

(d)

Technical guidance. Guidance for nonstructural stormwater management strategies is available in the New Jersey Stormwater Best Management Practices Manual. The BMP Manual may be obtained from the address identified in Subsection G below, or found on the Department's Web site at www.njstormwater.org.

(3)

Erosion control standards. The minimum design and performance standards for erosion control are those established under the Soil Erosion and Sediment Control Act, N.J.S.A. 4:24-39 et seq., and implementing rules.

(4)

Groundwater recharge standards. The minimum design and performance standards for groundwater recharge are as follows:

(a)

Recharge volume. The design engineer shall, using the assumptions and factors for stormwater runoff and groundwater recharge calculations at § 190-83D(4) and (5), either:

[1]

Demonstrate through hydrologic and hydraulic analysis that the site and its stormwater management measures maintain 100% of the average annual preconstruction groundwater recharge volume for the site; or

[2]

Demonstrate through hydrologic and hydraulic analysis that the increase of stormwater runoff volume from preconstruction to postconstruction for the two-year storm is infiltrated.

(b)

Calculations. Groundwater recharge may be calculated in accordance with the New Jersey Geological Survey Report GSR-32, A Method for Evaluating Ground-Water 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 http://www.state.nj.us/dep/njgs/; or at New Jersey Geological Survey, 29 Arctic Parkway, P.O. Box 427, Trenton, New Jersey 08625-0427; (609) 984-6587.

(c)

Prohibited recharge. 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 a 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.

(d)

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 and other subsurface structures in the vicinity or downgradient of the groundwater recharge area.

(5)

Runoff quantity standards.

(a)

Preconstruction runoff rates to be maintained. In order to control stormwater runoff quantity impacts, the design engineer shall, using the assumptions and factors for stormwater runoff calculations at § 190-83D(5)(b), complete one of the following:

[1]

Demonstrate through hydrologic and hydraulic analysis that for stormwater leaving the site, postconstruction runoff hydrographs for the two-, ten- and one-hundred-year storm events do not exceed, at any point in time, the preconstruction runoff hydrographs for the same storm events;

[2]

Demonstrate through hydrologic and hydraulic analysis that there is no increase, as compared to the preconstruction condition, in the peak runoff rates of stormwater leaving the site for the two-, ten- and one-hundred-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; or

[3]

Design stormwater management measures so that the postconstruction peak runoff rates for the two-, ten- and one-hundred-year storm events are 50%, 75% and 80%, respectively, of the preconstruction peak runoff rates. The percentages apply only to the postconstruction stormwater runoff that is attributable to the portion of the site on which the proposed development or project is to be constructed. The percentages shall not be applied to postconstruction stormwater runoff into tidal flood hazard areas if the increased volume of stormwater runoff will not increase flood damages below the point of discharge.

(b)

Calculation methodology. Stormwater runoff shall be calculated in accordance with the following:

[1]

The design engineer shall calculate runoff using one of the following methods:

[a]

The USDA Natural Resources Conservation Service (NRCS) methodology, including the NRCS Runoff Equation and Dimensionless Unit Hydrograph, as described in the NRCS National Engineering Handbook Section 4 - Hydrology and Technical Release 55 - Urban Hydrology for Small Watersheds; or

[b]

The Rational Method for peak flow and the Modified Rational Method for hydrograph computations.

[2]

For the purpose of calculating runoff coefficients and groundwater recharge, there is a presumption that the preconstruction 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 at § 190-83D(5)(b)[1][a] and the Rational and Modified Rational Methods at § 190-83D(5)(b)[1][b]. 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).

[3]

In computing preconstruction 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 preconstruction stormwater runoff rates and volumes.

[4]

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 and other methods may be employed.

[5]

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. The Village Engineer may also require that the outfall pipe be equipped with a backflow prevention measure such as tide gate.

(6)

Runoff quality standards. Stormwater management measures shall only be required for water quality control if an additional 1/4 acre (10,890 square feet) or more of impervious surface is being proposed on a development site. Such measures shall comply with the following requirements:

(a)

Suspended solids, Stormwater management measures shall be designed to reduce the postconstruction load of total suspended solids (TSS) in stormwater runoff by 80% of the anticipated load from the developed site, expressed as an annual average. 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 Pollution Discharge Elimination System (NJPDES) rules, N.J.A.C. 7:14A, or in a discharge specifically exempt under a NJPDES permit from this requirement.

[1]

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 1. The calculation of the volume of runoff may take into account the implementation of nonstructural and structural stormwater management measures.

For purposes of TSS reduction calculations, Table 2 below presents the presumed removal rates for certain BMPs designed in accordance with the New Jersey Stormwater Best Management Practices Manual. The BMP Manual may be obtained from the address identified in Subsection G below, or found on the Department's Web site at www.njstormwater.org. The BMP Manual and other sources of technical guidance are listed in § 190-83D(9). TSS reduction shall be calculated based on the removal rates for the BMPs in Table 2 below. Alternative removal rates and methods of calculating removal rates may be used if the design engineer provides documentation demonstrating the capability of these alternative rates and methods to the review agency. A copy of any approved alternative rate or method of calculating the removal rate shall be provided to the Department at the following address: Division of Watershed Management, New Jersey Department of Environmental Protection, P.O. Box 418, Trenton, New Jersey 08625-0418.

[3]

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 - (AXB)/100
	Where
	R = total TSS percent load removal from application of both BMPs
	A = TSS percent removal rate applicable to the first BMP
	B = TSS percent removal rate applicable to the second BMP

	Table 2 TSS Removal Rates for BMPs
	Best Management Practice	TSS Percent Removal Rate
	Bioretention systems	90%
	Constructed stormwater wetland	90%
	Extended detention basin	40% to 60%
	Infiltration structure	80%
	Manufactured treatment device	See § 190-83D(7)(a)[5]
	Sand filter	80%
	Vegetative filter strip	60% to 80%
	Wet pond	50% to 90%

[4]

If there is more than one on-site drainage area, the eighty-percent TSS removal rate shall apply to each drainage area, unless the runoff from the subareas converges on site, in which case the removal rate can be demonstrated through a calculation using a weighted average.

(b)

Nutrients. Stormwater management measures shall also be designed to reduce, to the maximum extent feasible, the postconstruction 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 nonstructural strategies and structural measures that optimize nutrient removal while still achieving the performance standards in § 190-83D(3) through (6).

(c)

Additional information. Additional information and examples are contained in the New Jersey Stormwater Best Management Practices Manual, which may be obtained from the address identified in § 190-83D(9).
