On January 6, 2017, the U.S. Army Corps of Engineers (Corps) published the notice in the Federal Register announcing the reissuance of all 50 existing nationwide permits (NWPs), general conditions, and definitions with some modifications. The Corps also issued two new NWPs, one new general condition, and five new definitions. The 2017 NWPs will go into effect on March 19, 2017, and will expire on March 18, 2022. With the publication of this Federal Register notice, Corps districts will begin finalizing their regional conditions for the new and reissued NWPs. Regional conditions will provide additional protection for the aquatic environment, and will help ensure that the NWPs authorize only those activities with no more than minimal adverse environmental effects. Regional conditions will help ensure protection of high value waters within the St. Louis District. The publication of this Federal Register notice also begins the 60-day period for states, Tribes, and the Environmental Protection Agency (EPA) to complete their water quality certification (WQC) processes for the NWPs. The 60-day period for WQC will end on March 6, 2017. This Federal Register notice also begins the 90-day period for coastal states to complete their Coastal Zone Management Act (CZMA) consistency determination processes. The 90-day period for CZMA consistency determinations will end on April 5, 2017.
