Section 7:50-6.86 - Water management

(a) Water shall not be exported from the Pinelands except as otherwise provided at N.J.S.A. 58:1A-7.1.

(b) A diversion that involves the interbasin transfer of water from sources within the Pinelands Area between the Atlantic Basin and the Delaware Basin, as defined at (b)1 and 2 below, or outside of either basin, shall be prohibited.

1. The Atlantic Basin is comprised of Watershed Management Areas 13, 14, 15, and 16, as identified by the New Jersey Department of Environmental Protection at http://www.state.nj.us/dep/seeds/docs/watersheds.pdf.

2. The Delaware Basin is comprised of Watershed Management Areas 17, 18, 19, and 20 as identified by the New Jersey Department of Environmental Protection at http://www.state.nj.us/dep/seeds/docs/watersheds.pdf.

(c) A diversion involving the intrabasin transfer of water between HUC-11 watersheds in the same basin, Atlantic Basin or Delaware Basin as defined at (b) above, shall be permitted. If such an intrabasin transfer involves water sourced from the Kirkwood-Cohansey aquifer, the diversion shall meet the criteria and standards set forth at (d) below.

(d) A new diversion or an increase in allocation from either a single existing diversion source or from combined existing and new diversion sources in the same HUC-11 watershed and in the Kirkwood-Cohansey aquifer, that results in a total diversion of 50,000 gallons of water per day or more (hereafter referred to as "proposed diversion") shall meet the criteria and standards set forth at (d)3 through 9 below. "Allocation" shall mean a diversion permitted pursuant to a Water Allocation Permit or Water Use Registration Number issued by the New Jersey Department of Environmental Protection pursuant to N.J.A.C. 7:19.

1. When evaluating whether the proposed diversion meets the criteria set forth at (d)3 through 9 below, all of the applicant's allocations in an HUC-11 watershed, in addition to the proposed diversion, shall be included in the evaluation.

2. The standards set forth at (d)3 through 9 below shall not apply to:

i. A new well that is to replace an existing well, provided the existing well is decommissioned in accordance with N.J.A.C. 7:9D-3 and the new replacement well will:

(1) Be approximately the same depth as the existing well;

(2) Divert from the same aquifer as the existing well;

(3) Have the same or lesser pump capacity as the existing well; and

(4) Be located within 100 feet of, and in the same HUC-11 watershed as, the existing well;

ii. Any proposed diversion that is exclusively for agricultural or horticultural use ; or

iii. Any proposed diversion for a resource extraction operation that constitutes a nonconsumptive use, provided the water returned to the source is not discharged to a stream or waterbody or otherwise results in offsite flow, and the diversion and return are located on the same parcel.

3. A proposed diversion shall be permitted only in the following Pinelands Management Areas:

i. Regional Growth Area;

ii. Pinelands Towns;

iii. Rural Development Area;

iv. Agricultural Production Area;

v. Military and Federal Installation Area; and

vi. The following Pinelands Villages: Milmay; Newtonville; Richland; Folsom; Cologne-Germania; Pomona; Mizpah; Nesco-Westcoatville; Port Republic; New Gretna; New Lisbon; Indian Mills; Tabernacle; Blue Anchor; Elm; Tansboro; Waterford Works; Winslow; Dennisville; Petersburg; Tuckahoe; Delmont; Dorchester; and Port Elizabeth-Bricksboro.

4. A proposed diversion shall only be permitted if the applicant demonstrates that no alternative water supply source is available or viable. Alternative water supply sources include, but are not limited to, groundwater and surface water sources that are not part of the Kirkwood-Cohansey aquifer, and public water purveyors and suppliers, as defined at N.J.A.C. 7:19-1.3. A list of alternative water supply sources is available at the offices of the Pinelands Commission and at http://www.nj.gov/pinelands/.

5. A proposed diversion shall not have an adverse ecological impact on the Kirkwood-Cohansey aquifer. Adverse ecological impact means an adverse regional impact and/or an adverse local impact, as described at (d)6 and 7 below.

6. A proposed diversion shall be deemed to have an adverse regional impact if it, combined with all current depletive-consumptive net use in the same HUC-11 watershed, exceeds 20 percent of the stream low flow margin for the year of peak use . For this analysis, applicants shall use Appendix A of the New Jersey Statewide Water Supply Plan at http://www.state.nj.us/dep/watersupply/pdf/wsp-appendix-a.pdf, as amended and supplemented, and refer to the HUC-11 watershed where the proposed diversion will be located (hereafter referred to as "the affected HUC-11 watershed"). Applicants shall use the tables in Appendix A entitled "Summary of HUC-11 area, Low Flow Margin and Remaining Water" and specifically, the values for the HUC-11 Low Flow Margin in the column labeled LFM (mgd) and the values for current depletive-consumptive net use in the column labeled "Current Net Dep-Con (mgd)."

i. If a proposed diversion is deemed to have an adverse regional impact, it shall be permitted only if an applicant permanently offsets the diversion on a gallon-for-gallon basis in accordance with the following:

(1) Offsets shall be implemented in the affected HUC-11 watershed and include, but are not limited to:

(A) The recharge of previously non-infiltrated stormwater runoff in the Pinelands Area;

(B) The recharge of treated wastewater that is currently discharged by a regional sewage treatment plant that discharges treated wastewater into the Delaware River or Atlantic Ocean;

(C) Development of a desalinization facility; and

(D) Sewerage system inflow and infiltration abatement and/or water distribution infrastructure leak auditing and correction.

ii. A proposed diversion in an HUC-11 watershed where water withdrawals already exceed 20 percent of the stream low flow margin established in the New Jersey Statewide Water Supply Plan shall be deemed to have an adverse regional impact unless an applicant can permanently offset the entire diversion in accordance with (d)6i(1) above.

iii. Unless the submission requirements are modified or waived pursuant to N.J.A.C. 7:50-4.2(b)3, all applications shall include the information required at N.J.A.C. 7:50-4.2(b)4 or 5, as well as the following:

(1) Using data on low flow margins in the New Jersey Statewide Water Supply Plan in effect at the time of application, the applicant shall calculate the sum of the proposed diversion and all existing permitted allocations in the affected HUC-11 watershed, and show whether that sum exceeds 20 percent of the stream low flow margin for the year of peak use established in the New Jersey Statewide Water Supply Plan. The applicant shall submit a report that includes all required calculations and a summary of the impact of the proposed diversion on the available portion of the 20 percent stream low flow margin in the affected HUC-11.

(2) The applicant shall identify all offset measures and provide to the Commission a detailed description of the measures, including the volume of water that will be offset, timeframes for implementing the offsets, a description of the entity that will be implementing the offset measures, and an explanation of the entity's authority to implement the measures.

7. A proposed diversion shall be deemed to have an adverse local impact in the Pinelands Area if it results in the drawdown of the water table as defined at N.J.A.C. 7:19-6.2 of any portion of the Preservation Area District, Forest Area, or Special Agricultural Production Area in the affected HUC-11 watershed, or of more than four inches of the wetlands nearest to the estimated zone of influence in the affected HUC-11 watershed.

i. Application requirements:

(1) The applicant shall submit an analysis of potential drawdown impacts using the Thiem method in accordance with the New Jersey Geological & Water Survey Technical Memorandum 12-2, Hydrogeologic Testing and Reporting Procedures in Support of New Jersey Water Allocation Permit in effect at the time of application (hereafter referred to as "TM 12-2").

(2) Upon completion of the Thiem analysis, the applicant shall submit a proposed hydrogeologic test procedure, developed in accordance with TM 12-2, which shall include, at a minimum, the installation of:

(A) A single pumping well;

(B) Observation wells to sufficiently monitor water levels while the test well is pumped at a constant rate;

(C) Observation wells to collect time-drawdown data for aquifer characterization; and

(D) At least one piezometer to measure surface water and water table decline at: the nearest boundaries of the Preservation Area District, Forest Area, or Special Agricultural Production Area in the affected HUC-11 watershed found in any direction from the proposed well location; and the wetlands nearest to the estimated zone of influence in the affected HUC-11 watershed.

I. If the applicant cannot gain access to the parcels at the locations listed at (d)7i(2)(D) above for placement of piezometer(s), the applicant may propose to install piezometers at comparable locations if the alternate placement will adequately measure surface water and water table decline at the locations listed at (d)7i(2)(D) above.

II. Piezometers shall be tested to ensure hydraulic responsiveness and the results of such testing shall be included in the report submitted pursuant to (d)7i(3) below;

(3) Following the Commission's review of the hydrogeologic test procedure, the applicant shall complete the test and submit a final hydrogeologic report prepared in accordance with the "Hydrogeological Report" section of TM 12-2, which shall describe the field procedures used, all data gathered, analysis of the data, and evaluation of the effect of the proposed diversion on the Kirkwood-Cohansey aquifer.

(4) Using the results of the hydrogeologic testing performed in accordance with (d)7i(3) above, the applicant shall calculate an estimated zone of influence created by the proposed diversion and submit a groundwater flow model using the modular hydrologic model of the United States Geological Survey, (MODFLOW) in use at the time of the application. The MODFLOW model shall calculate the zone of influence of the water table at: the nearest boundaries of the Preservation Area District, Forest Area, or Special Agricultural Production Area in the affected HUC-11 watershed; and the boundary of the wetland nearest to the proposed diversion in the same HUC-11 watershed.

8. An applicant for a proposed diversion shall provide written documentation of water conservation measures that have been implemented, or that are planned for implementation, for all areas to be served by the proposed diversion. Water conservation measures are measurable efforts by public and private water system operators and local agencies to reduce water demand by users and reduce losses in the water distribution system.

9. The following notice requirements shall apply to the proposed diversions:

i. For applications submitted pursuant to N.J.A.C. 7:50-4.31 through 4.50, the applicant shall provide notice of the application to the municipality and county in which the proposed diversion will be located, as well as all other municipalities and counties in the affected HUC-11 watershed. The notice shall state:
