Nationwide Permit Program

The U.S. Army Corps of Engineers (Corps) issues nationwide permits (NWPs) to authorize certain activities that require Department of the Army permits under Section 404 of the Clean Water Act and/or Section 10 of the Rivers and Harbors Act of 1899.  The NWPs authorize activities that have minimal individual and cumulative adverse effects on the aquatic environment.  The NWPs authorize a variety of activities, such as aids to navigation, utility lines, bank stabilization activities, road crossings, stream and wetland restoration activities, residential developments, mining activities, commercial shellfish aquaculture activities, and agricultural activities.
