Air Plan Approval; Maryland; Reasonably Available Control Technology for Municipal Waste Combustors
What happened
The U.S. Environmental Protection Agency (EPA) approved state implementation plan (SIP) revisions from Maryland. These revisions implement statewide reasonably available control technology (RACT) requirements, specifically limiting air emissions of oxides of nitrogen (NOX) from municipal waste combustors (MWCs) in Maryland. This action, taken under the Clean Air Act (CAA), is effective on November 9, 2026, and was signed by Donald Trump.
Why it matters
This policy aims to reduce air pollution by controlling emissions from waste-burning facilities, helping to improve air quality in Maryland. Reducing oxides of nitrogen (NOX) is an important strategy for limiting photochemical reactions that cause ozone formation. The Clean Air Act requires states to implement such controls in areas designated as nonattainment for ozone.
