American Cement Association Statement Regarding Petition Filed Imploring the U.S. Supreme Court to Review EPA's 2024 PM 2.5 RuleÂ

WASHINGTON, D.C. (August 28, 2026)- As part of a coalition spearheaded by the U.S. Chamber of Commerce, the American Cement Association (ACA) has formally asked the U.S. Supreme Court to review a D.C. Circuit decision upholding a Biden-era Environmental Protection Agency (EPA) rule for fine particulate matter (PM 2.5).

"Keeping the PM 2.5 rule in place would be going completely against what the current Administration has been fighting so hard for in American manufacturing," said Sean O'Neill, ACA's Senior Vice President of Government Affairs.

"This rule imposes overreaching and technologically unfeasible limits, which will lessen-not strengthen- cement production at our plants and directly interferes with our country's ability to provide unparalleled national security and the resilient, dependable concrete infrastructure used by all Americans every day.

A regulatory system that provides no practical margin for growth or reinvestment risks discouraging projects that would advance environmental progress.

The PM 2.5 rule does not balance environmental stewardship with economic reality; instead, it penalizes the very industry that is building America's future."
