Permits Types
In the District of Columbia, we use two types of General Permits to authorize work: Nationwide Permits (NWPs), and the Chesapeake Bay Total Maximum Daily Load (TMDL) Regional General Permit (TMDL RGP). These General Permits may be used to authorize impacts to waters of the United States that have been determined to result in no more than minimal adverse environmental effects. The majority of projects qualify for authorization under one of these General Permits. For projects with the potential for more than minimal environmental impacts, authorization may be obtained through a Letter of Permission or an Individual Permit. Additional information on NWPs, Letters of Permission and Individual Permits may be found on our Permit Types and Processes page. Information on the TMDL RGP may be found on our TMDL page.
In some instances, issued authorizations may require compensatory mitigation to offset unavoidable impacts to aquatic resource functions and services. Information on compensatory mitigation requirements may be found on our Mitigation page.
Nationwide Permits
Nationwide Permits (NWPs) are general permits issued on a nationwide basis to authorize minor activities with minimal evaluation time. NWPs have been established to reduce the regulatory reporting burden for specific activities that have no more than minimal impacts to the aquatic environment.
