Freshwater Wetlands - Application Guidance
Airport Sight Line Clearing (General Permit 9)

  • Overview
  • Application Guidance
  • Rules
  • FAQ

General Permit Number 9 (GP9) permits the cutting of vegetation only as necessary to comply with the protected air space provisions for a public use aeronautical facility, mandated by the Federal Aviation Administration (FAA) and set forth in the New Jersey Department of Transportation rules at N.J.A.C. 16:54-4.2. In other words, when, there would be selective cutting of certain vegetation in freshwater wetlands and transition areas, at airports (aeronautical facility)* used by the public, then a General Permit 9 is required.

*As defined in the New Jersey Department of Transportation (NJDOT) rules at N.J.A.C. 16:54-1.3

This page is for informational purposes only. Please see N.J.A.C. 7:7A-5.9 for the precise rules concerning this General Permit.

Only activities necessary to enable an aeronautical facility to comply with New Jersey Department of Transportation rules. The cutting of vegetation in wetlands and/or transition areas as part of a project that increases the area of pavement or buildings at an airport is not authorized under general permit 9, and would require an individual permit.

Getting a GP9: If you believe that your project will require a GP9, 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 required. 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.
