Air Permitting Improvements to Protect National Security Act of 2025

This bill amends the Clean Air Act to allow the President to waive emission offset requirements for advanced manufacturing and critical mineral facilities for national security reasons, and to let states use alternative offset methods for such facilities.

Sec. 2, Supporting Critical Manufacturing: This section adds two new provisions to the Clean Air Act. First, it creates a National Security Waiver: upon application, the President may waive any requirement for a new or modified advanced manufacturing or critical mineral facility to offset increased emissions of any air pollutant, if the President determines it is in the national security interests of the United States. The President cannot delegate this determination. Second, it establishes alternative requirements: a state permitting authority must allow such facilities to offset emissions by alternative or innovative means if the source shows it has used all reasonable means to obtain offsets, all available offsets are being used, and sufficient offsets are not available. The source must then comply with an alternative measure imposed by the authority, or pay an emissions fee no greater than 1.5 times the average cost of stationary source control measures in that area over the previous 3 years. The fees must be used to maximize emissions reductions. The section defines 'advanced manufacturing facility' as one primarily for manufacturing semiconductors or semiconductor manufacturing equipment, and 'critical mineral facility' as one primarily for extraction, processing, refining, or milling of a critical mineral designated by the Secretary of the Interior.
