Last Friday, the U.S. Supreme Court declined to pause the Biden administration’s new federal air pollution rules to tighten limits on mercury and methane.

The regulations, issued under the Clean Air Act, aim to cut mercury and other metals from coal-fired power plants emissions, as well as methane and other gases known as volatile organic compounds from oil and gas production.

For manufacturers, particularly those in the energy industry, the new rules will likely result in increased operational costs in the form of costly upgrades in monitoring equipment, curb flaring, and participation in programs to detect large methane emissions.10/2/2024
