    On September 15, 2020, the U.S. Army Corps of Engineers published in the Federal Register its proposal to reissue the 52 existing nationwide permits (NWPs) and issue five new NWPs. Nationwide permits are general permits issued on a nationwide basis to streamline the authorization of activities that result in no more than minimal individual and cumulative adverse environmental effects. Many of the proposed NWPs require notification to the district engineer before commencing those activities, to ensure that the activities authorized by those NWPs cause no more than minimal individual and cumulative adverse environmental effects.
