Nationwide Permits

Nationwide Permits (NWP) are a type of "general permit" issued by the U.S. Army Corps of Engineers. Projects which are relatively routine and are minor in nature may qualify for a Nationwide Permit. Nationwide Permits cover specific construction activities such as installing culverts for a small road crossing, or for using rip rap to stabilize a stream bank to prevent erosion. Presently, there are 49 Nationwide Permits issued to the public for various activities like those described above. In each case, there are specific thresholds regarding area and/or volume of impact that can result from the project, and each Permit includes a set of General and Regional Conditions to which the work must conform. If your proposed work qualifies for use of a Nationwide Permit, the Corps will help verify this and will issue you an authorization to use the Permit.
