Denial of Petitions for Reconsideration
April 21, 2015 – EPA completed the review of the remaining requests to reconsider certain aspects of the Mercury and Air Toxics Standards (MATS) for power plants. After careful consideration, EPA has decided to deny all remaining requests - a step that affirms the agency’s approach in the final MATS rule and provides stakeholders with certainty moving forward.
