In March 2025, the United States Environmental Protection Agency (EPA) announced that it has set up an electronic mailbox to allow stationary sources to request a presidential exemption from certain standards under Section 112 of the Clean Air Act (CAA).
Section 112 requires EPA to establish emission standards for certain stationary sources of hazardous air pollutants. Section 112 also includes a provision that enables the president to exempt stationary sources from compliance with any standard or limitation under Section 112 for up to two years if “the President determines that the technology to implement such standard is not available and that it is in the national security interests of the United States to do so.” 42 U.S.C. § 7412(i)(4). Section 112(i)(4) also provides that such an exemption may be extended “for 1 or more additional periods, each period not to exceed 2 years.”
