  • Overview
  • Application Guidance
  • Rules
  • FAQ

General Permit Number 13 (GP13) permits up to one acre of dredging in palustrine emergent freshwater wetlands necessary to restore or maintain a lake, pond or reservoir to it’s original bottom contours. GP 13 Does NOT authorize disturbance of wetlands that are not palustrine emergent freshwater wetlands, or in transtion areas, except as necessary to obtain access to a dredging project.

This page is for informational purposes only. Please see N.J.A.C. 7:7A-5.13 for the precise rules concerning this General Permit.

In accordance with N.J.A.C. 7:7A-2.2(b), if a dredging project meets all the following
criteria, the project does NOT require Department approval under this chapter:

  1. The project disturbs State open waters only, and does not disturb wetlands located in the
    lake, pond, or reservoir;
  2. The project does not disturb wetlands or transition areas adjacent to the lake, pond, or
    reservoir; and
  3. The project does not involve the discharge of dredged or fill material in the State open
    water. For example, if the project involves placement of fill in a lake bed for an access
    road, or involves temporary placement of dredged material on the lake bed prior to
    removal of the dredged material, the project would be regulated and would require Department approval.

Dredged material must be disposed of in accordance with the requirements in the standard conditions for all general permits at N.J.A.C. 7:7A-4.3. The Department may require testing of dredged material if there is reason to suspect that the material is contaminated.

Activities under general permit 13 shall comply with all applicable requirements at N.J.A.C.
7:7A-4.3, Conditions that apply to all general permits, and N.J.A.C. 7:7A-13.1, Establishing
permit conditions.
