(D) If the potential for contamination of stormwater runoff by petroleum products exists onsite, prior to being conveyed to the stormwater management measure required at (a)6iv(5)(C) above, the stormwater runoff from the HPLAs and areas where stormwater runoff is exposed to source material shall be conveyed through an oil/grease separator or other equivalent manufactured filtering device providing for the removal of petroleum hydrocarbons.

(6) For all major development, as defined at N.J.A.C. 7:50-2.11, stormwater management measures shall be designed to achieve a minimum of 65 percent reduction of the post-construction total nitrogen load from the developed site, including those permanent lawn or turf areas that are specifically intended for active human use as described at N.J.A.C. 7:50-6.24(c)3, in stormwater runoff generated from the water quality design storm. In achieving a minimum 65 percent reduction of total nitrogen, the design of the site shall include green infrastructure in accordance with the BMP Manual and shall optimize nutrient removal. The minimum 65 percent total nitrogen reduction may be achieved by using a singular stormwater management measure or multiple stormwater management measures in series.

v. Stormwater management measure design, siting, and construction standards:

(1) Stormwater management measures designed to infiltrate stormwater shall be designed, constructed, and maintained to provide a minimum separation of at least two feet between the elevation of the lowest point of infiltration and the seasonal high water table;

(2) Stormwater management measures designed to infiltrate stormwater shall be sited in suitable soils verified by testing to have permeability rates between one and 20 inches per hour. A factor of safety of two shall be applied to the soil's permeability rate in determining the infiltration measure's design permeability rate. If such soils do not exist on the parcel proposed for development or if it is demonstrated that it is not practical for engineering, environmental, or safety reasons to site the stormwater infiltration measure(s) in such soils, the stormwater infiltration measure(s) may be sited in soils verified by testing to have permeability rates in excess of 20 inches per hour, provided that stormwater is routed through a bioretention system prior to infiltration. Said bioretention system shall be designed, installed, and maintained in accordance with the New Jersey Stormwater Best Management Practices Manual;

(3) For all major development, as defined at N.J.A.C. 7:50-2.11, groundwater mounding analysis shall be required for purposes of assessing the hydraulic impacts of mounding of the water table resulting from infiltration of stormwater runoff from the maximum storm designed for infiltration. The mounding analysis shall provide details and supporting documentation on the methodology used. Groundwater mounds shall not cause stormwater or groundwater to breakout to the land surface or cause adverse impacts to adjacent water bodies, wetlands, or subsurface structures, including, but not limited to, basements and septic systems. Where the mounding analysis identifies adverse impacts, the stormwater management measure shall be redesigned or relocated, as appropriate;

(4) The use of stormwater management measures that are smaller in size and distributed spatially throughout a parcel, rather than the use of a single, larger stormwater management measure shall be required;

(5) Methods of treating stormwater prior to entering any stormwater management measure shall be incorporated into the design of the stormwater management measure to the maximum extent practical;

(6) To avoid sedimentation that may result in clogging and reduction of infiltration capability and to maintain maximum soil infiltration capacity, the construction of stormwater management measures that rely upon infiltration shall be managed in accordance with the following standards:

(A) No stormwater management measure shall be placed into operation until its drainage area has been completely stabilized. Instead, upstream runoff shall be diverted around the measure and into separate, temporary stormwater management facilities and sediment basins. Such temporary facilities and basins shall be installed and utilized for stormwater management and sediment control until stabilization is achieved in accordance with N.J.A.C. 2:90, Standards for Soil Erosion and Sediment Control in New Jersey;

(B) If, for engineering, environmental, or safety reasons, temporary stormwater management facilities and sediment basins cannot be constructed on the parcel in accordance with (a)6v(6)(A) above, the stormwater management measure may be placed into operation prior to the complete stabilization of its drainage area provided that the measure's bottom during this period is constructed at a depth at least two feet higher than its final design elevation. When the drainage area has been completely stabilized, all accumulated sediment shall be removed from the stormwater management measure, which shall then be excavated to its final design elevation; and

(C) To avoid compacting the soils below a stormwater management measure designed to infiltrate stormwater, no heavy equipment, such as backhoes, dump trucks, or bulldozers shall be permitted to operate within the footprint of the stormwater management measure. All excavation required to construct a stormwater management measure that relies on infiltration shall be performed by equipment placed outside the footprint of the stormwater management measure. If this is not possible, the soils within the excavated area shall be renovated and tilled after construction is completed. Earthwork associated with stormwater management measure construction, including excavation, grading, cutting, or filling, shall not be performed when soil moisture content is above the lower plastic limit; and

(7) Dry wells shall be designed to prevent access by amphibian and reptiles.

vi. As-built requirements for major development, as defined at N.J.A.C. 7:50-2.11:

(1) After all construction activities have been completed on the parcel and finished grade has been established in each stormwater management measure designed to infiltrate stormwater, replicate post-development permeability tests shall be conducted to determine if as-built soil permeability rates are consistent with design permeability rates. The results of such tests shall be submitted to the municipal engineer or other appropriate reviewing engineer. If the results of the post-development permeability tests fail to achieve the minimum required design permeability rate, utilizing a factor of safety of two, the stormwater management measure shall be renovated and re-tested until the required permeability rates are achieved; and

(2) After all construction activities and required testing have been completed on the parcel, as-built plans, including as-built elevations of all stormwater management measures shall be submitted to the municipal engineer or other appropriate reviewing engineer to serve as a document of record. Based upon that engineer's review of the as-built plans, all corrections or remedial actions deemed necessary due to the failure to comply with design standards and/or for any reason concerning public health or safety, shall be completed by the applicant. In lieu of review by the municipal engineer, the municipality may engage a licensed professional engineer to review the as-built plans and charge the applicant for all costs associated with such review.

vii. Exceptions:

(1) For applications submitted pursuant to N.J.A.C. 7:50-4.31 through 4.50, a municipality may grant a variance in accordance with N.J.A.C. 7:8-4.6, as amended, from the on-site design and performance standards for green infrastructure, the standards for groundwater recharge, stormwater runoff quality, and stormwater runoff quality at N.J.A.C. 7:8-5.3, 5.4, 5.5, and 5.6, and the on-site recharge standards set forth at (a)6iv above, provided that:

(B) The proposed mitigation project shall be consistent with the stormwater management plan certified by the Commission pursuant to N.J.A.C. 7:50-3for the municipality in which the parcel proposed for development is located, unless said stormwater plan does not identify appropriate parcels or projects where mitigation may occur; and

(C) Any variance from the on-site recharge standards set forth at (a)6iv above shall require that the total volume of stormwater infiltrated by the mitigation project equals or exceeds the volume required at (a)6iv above.

(2) For applications submitted pursuant to N.J.A.C. 7:50-4.51 through 4.60, the Commission may grant an exception in accordance with the standards described at N.J.A.C. 7:8-4.6, as amended, from the on-site design and performance standards for green infrastructure, groundwater recharge, stormwater runoff quality, and stormwater runoff quality at N.J.A.C. 7:8-5.3, 5.4, 5.5, and 5.6 and on-site recharge standards set forth at (a)6iv above, provided the conditions set forth at (a)6vii(1) above are met.

(3) Unless specifically included at (a)6vii(1) and (2) above, the exemptions, exceptions, applicability standards, and waivers of strict compliance for stormwater management described at N.J.A.C. 7:8 shall not apply.

(4) No variances or exceptions shall be granted from (a)6iii(1) above, which prohibits the direct discharge of stormwater runoff to any wetlands, wetlands transition area, or surface waterbody and the direction of stormwater runoff in such a way as to increase in volume and rate of discharge into any wetlands, wetlands transition area, or surface water body from that which existed prior to development of the parcel.
