Current through Register Vol. 56, No. 21, November 4, 2024

Section 7:13-12.9 - Requirements for a stormwater outfall structure

(a) This section sets forth specific design and construction standards that apply to any stormwater outfall structure proposed in any regulated area.

(b) The Department shall issue an individual permit to construct or reconstruct a stormwater outfall structure only if the following requirements are satisfied:

1. The structure is built with a concrete headwall or flared-end section with footings that extend no less than three feet below grade;

2. The structure does not obstruct flow in a channel or floodway;

3. The structure includes adequate conduit outlet protection where required by the Standards for Soil Erosion and Sediment Control in New Jersey at N.J.A.C. 2:90, as determined by the local Soil Conservation District having jurisdiction over the site;

4. If the structure includes a rip-rap apron, a three feet deep by three feet wide rip-rap toe wall is constructed at the end of the apron; and

5. The structure does not interfere with the normal flow of the channel or threaten to change the dimensions or location of the channel. For example, a large discharge of stormwater into a small channel, or a discharge situated at a significant angle to the normal flow in a channel, may cause the channel to move over time, interfere with the direction of flow and/or cause increased erosion or deposition of sediment within the channel.
