The U.S. Environmental Protection Agency (EPA) says it is reviewing technical information that is focused on emissions limits for new power plants under the Mercury and Air Toxics Standards (MATS). The technical review is intended to clarify how the new standards would apply to five plants proposed in Texas, Georgia, Kansas and Utah. The review is based on new information provided by industry stakeholders after the rule was finalized.
EPA says the review, known as a “reconsideration,” will not change the rules for existing facilities, which were issued in January.
EPA will review monitoring issues related to the mercury standards for new power plants and will address other technical issues on the acid gas and particle pollution standards for these plants. The agency’s review will not change the types of emissions controls new power plants are expected to use to reduce this harmful pollution.
Reconsiderations are a routine tool that EPA often uses to ensure that its standards incorporate all relevant information, in cases where information only becomes available after a rule is promulgated.
The agency will complete the rulemaking by March 2013 and will stay the final standards for new power plants for three months during this review.
