2060-AT99 201904 Unified Agenda of Federal Regulatory and Deregulatory Actions 2060 Office of Air and Radiation OAR 2000 Environmental Protection Agency EPA NESHAP: Coal- and Oil-Fired Electric Utility Steam Generating Units--Reconsideration of Supplemental Cost Finding and Residual Risk and Technology Review

This rulemaking will take final action related to two of the three distinct actions included in EPA's February 7, 2019, proposal (84 FR 2670) regarding the National Emission Standards for Hazardous Air Pollutants: Coal- and Oil-Fired Electric Utility Steam Generating Units (commonly referred to as the Mercury and Air Toxics Standards (MATS)), 40 CFR 63, subpart UUUUU. First, EPA proposed a revised response to the U.S. Supreme Court decision in Michigan v. EPA which held that EPA erred by not considering cost in its determination that regulation of hazardous air pollutant (HAP) emissions from coal- and oil-fired electric utility steam generating units (EGUs) is appropriate and necessary under section 112 of the Clean Air Act (CAA). Second, EPA proposed the results of the residual risk and technology review (RTR) of MATS as required by CAA section 112.
