Section 7:45-8.3 - Specific standards for outfalls

(a) For projects involving new or existing outfalls in the Review Zone, the following standards shall be required:

1. New outfalls to the Canal are prohibited;

2. New sources of stormwater that tie into drainage systems discharging into the Canal are prohibited;

3. New outfalls within stream corridors of water courses that discharge to the Canal are prohibited;

4. New outfall structures within the Park or within 300 feet of the Canal are prohibited; and

5. For projects discharging to existing outfalls in the Canal, the Commission shall consider the following prioritization of types of remediation measures:

i. Removal of the existing outfalls;

ii. Where the removal of existing outfalls is not possible under (a)5i above, stormwater being discharged through the outfall shall be treated to achieve 95 percent TSS removal for the water quality design storm, as described at N.J.A.C. 7:45-8.7; or

iii. Where treatment for stormwater is not possible under (a)5ii above, stormwater from offsite areas shall be treated to achieve 95 percent total suspended solids (TSS) removal as follows:

(1) Water quality treatment shall be provided for a developed area within the Canal's drainage basin that does not receive water quality treatment. The water quality treatment must achieve one of the following:

(A) An equivalent reduction in TSS loadings for twice the volume of stormwater generated by the proposed project during the water quality design storm; or

(B) An equivalent reduction in TSS loadings for twice the flow rate generated by the proposed project during the water quality design storm.

(b) An applicant shall provide clear and convincing documentation to demonstrate that a proposed project requires use of an existing outfall into the Canal, and that the remediation measures in (a)5 above cannot be met. If the applicant so demonstrates, alternative compensatory measures including offsite mitigation for water quality must then be provided, in accordance with N.J.A.C. 7:45-12.6, Waiver of stormwater runoff and water quality.
