EPA Review of the Mercury and Air Toxics Standards Residual Risk and Technology Review
Posted by [email protected] on Apr. 10, 2023
EPA is proposing to strengthen and update the National Emission Standards for Hazardous Air Pollutants for Coal- and Oil-Fired Electric Utility Steam Generating Units (EGUs), commonly known as the Mercury and Air Toxics Standards (MATS) for power plants, to reflect recent developments in control technologies and the performance of these plants. This proposed rule reflects the most significant improvements and updates to MATS since EPA first issued these standards in February 2012. It also fulfills EPA’s responsibility under the Clean Air Act to periodically re-evaluate its standards in light of advancements in pollution control technologies to determine whether revisions are necessary.
