Ninth Circuit Tosses NWP 12 Appeal

On August 11, 2021, the U.S. Court of Appeals for the Ninth Circuit granted partial vacatur of an appeal brought by the U.S. Army Corps of Engineers (Corps) challenging a district court decision to vacate and enjoin use of the 2017 version of nationwide permit 12 (NWP 12).

Nationwide Permit 12 (NWP 12) Vacated on ESA Grounds
