General Permit Number 18 (GP18) authorizes activities necessary to repair, rehabilitate, replace, maintain, reconstruct or remove a dam in a freshwater wetland, transition area and/or State open water.
In order to determine whether or not an area of freshwater wetlands, transition areas or State open waters may be disturbed by any proposed activity, detailed information about that wetlands and the site must be obtained, and an inspection of the property by a representative of the Department is required. The Department offers a “Letter of Interpretation" (LOI), which is a document that may describe if there are wetlands on the property, and if so, where they are located.
This page is for informational purposes only. Please see N.J.A.C. 7:7A-5.18 for the precise rules concerning this General Permit.
The Department shall issue a General Permit 18 authorization only if the dam is currently serviceable. A dam that is not currently serviceable, as defined, may not be repaired, rehabilitated, replaced, maintained or reconstructed, but may be removed.
