N.J.A.C. 7:7A-5.5 General Permit 5--Landfill closures

When, as part of a landfill closure , there would be disturbance to freshwater wetlands, freshwater wetland transition areas and/or State open waters that are undertaken by the Department's Division of Solid and Hazardous Waste, or authorized through a solid waste facility closure and post-closure plan or disruption approval issued by the Department under N.J.A.C. 7:26-2A.9, a General Permit 5 is required.

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-5.5 for the precise rules concerning this General Permit.

General permit 5 authorizes a disturbance authorized through a closure plan, post-closure plan, or disruption approval only if:

  1. The activities that will cause the disturbance are necessary to properly close the solid waste facility and to properly maintain and monitor it after closure. For example, an access road necessary for landfill closure may be authorized under general permit 5, but an access road that is not necessary for landfill closure, but that will facilitate development of the site, is not authorized under general permit 5; and
  2. The amount of disturbance is the minimum necessary in order to adequately close and/or maintain the landfill. For example, a disturbance for an access road through wetlands may be necessary to properly close the landfill, but the road shall be the minimum size possible.

Mitigation: There is no acreage limit on activities under General Permit 5. However, mitigation shall be performed to compensate for disturbance of freshwater wetlands and/or State open waters authorized under General Permit 5, except that mitigation is not required for disturbance of wetlands located on top of the landfill, or on the intermediate or permanent cover of the landfill. The mitigation shall meet the procedural and substantive requirements at N.J.A.C. 7:7A-15. The applicant should submit as part of the general permit application a mitigation plan when required. Mitigation shall be performed prior to or concurrently with the landfill closure or disruption activities. Please note the Department shall not issue an authorization under General Permit 5 until the mitigation proposal is approved if one is required.

Getting a GP5: If you believe that your project will require a GP5, and you do not know how to apply for one, we suggest that you visit "The Permit Process" section of this website for more information. It will give you a general overview on the ins and outs of permitting, and will direct you to the forms necessary to apply. Please be advised that any application submitted must follow the procedures and information requireme. If you intend on applying for multiple freshwater wetland general permits, be advised that there are strict limits on what can and cannot be applied for, with a 1 acre cap on wetland disturbance for any one project site.

Note: The Department has, for your convenience, developed an Application Checklist for General Permits. Please follow carefully the requirements as outlined on this checklist to insure that you have all of the required information necessary to complete and process your application.
