Presidential Determination Concerning the Air Force’s Jet Fighter Training Operations in Idaho, Oregon, and Nevada

President Donald J. Trump issued a memorandum exempting the Air Force’s jet fighter training operations in Idaho, Oregon, and Nevada from federal, state, interstate, and local water-pollution control requirements and related enforcement processes. The exemption is made under section 313 of the Federal Water Pollution Control Act and applies for one year, from April 20, 2026, through April 20, 2027. The order says this step is being taken because Trump determined it is in the “paramount interest” of the United States. It also makes clear that the exemption does not cover certain Clean Water Act provisions in 33 U.S.C. 1316 and 1317, and it directs the Secretary of the Air Force to publish the determination in the Federal Register.
