Proclamation 10987, signed by President Trump on October 24, 2025, is a presidential exemption issued under section 112(i)(4) of the Clean Air Act. It temporarily suspends compliance requirements of a 2024 EPA rule governing air emissions from primary copper smelters for the specific facilities listed in the proclamation’s Annex I.
Every compliance deadline that the 2024 EPA Copper Rule set for the listed facilities is extended by two years from its original due date. During those two-year extension windows, each listed smelter remains subject only to the emissions standards that applied to it before the Copper Rule took effect — not the newer, stricter ones. The presidential determination accompanying the exemption states two official grounds: that the required control technology does not yet exist in commercially viable form, and that the exemption serves national security interests tied to domestic copper supply.
The direct beneficiaries are the specific primary copper smelting facilities named in Annex I of the proclamation — a small group, given that only two primary copper smelters were reported operating in the United States in 2024. Those facilities avoid having to meet the new EPA emission standards on the original schedule, gaining additional time before compliance is required.
