EPA has announced that the agency is reviewing new technical information associated with the new source limits for toxics emitted from new power plants under the Mercury and Air Toxics Standards (MATS). According to EPA, the new information indicates that there may be technical challenges associated with monitoring mercury emissions at the levels set for new power plants.
These new plants would continue to rely on the same proven pollution control technologies to reduce mercury, acid gases, and particle pollution. The agency believes this information warrants further review and will follow an expedited, open, and transparent process that includes public comment on any proposed changes. The agency will also use its Clean Air Act authority to stay the final standards for new power plants for 90 days during this technical review.
