Air Permitting Improvements to Protect National Security Act of 2025

HR 6373 modifies the Clean Air Act to create new permitting flexibility for specific facilities. It allows the President to waive certain emission offset requirements for new or modified semiconductor manufacturing facilities or critical mineral facilities (like those processing lithium or cobalt) if deemed necessary for national security. States can also permit these facilities to use alternative offset methods - such as paying an emissions fee capped at 1.5 times local control costs - if all standard offsets are exhausted, with fees required to fund further emissions reductions in the area. The bill directly affects advanced manufacturing and critical mineral operations seeking streamlined permitting.
