Trump exempts 180+ facilities from Clean Air Act air-toxics rules via an EPA email inbox
Across 2025, President Trump signed seven proclamations invoking Clean Air Act Section 112(i)(4) — a provision unused in the statute's 55-year history — to grant more than 180 industrial facilities in 38 states and Puerto Rico a two-year exemption from federal hazardous-air-pollutant standards. A May 2026 ProPublica investigation found that facilities qualified by emailing an EPA-run inbox, with no rigorous application and no meaningful role for the agency's air-quality experts. The statute permits such exemptions only where compliance technology is "not available" and the exemption is "in the national security interests of the United States."
