U.S. EPA Proposes Utility MACT to Reduce Mercury and Other Hazardous Air Pollutants from Power Plants

On March 16, 2010, the U.S. Environmental Protection Agency (“EPA”) proposed regulations that, when finalized, will establish emission limits for mercury and other hazardous air pollutants (“HAP”) for new and existing coal- and oil-fired power plants (the “Utility MACT”). The EPA is working to meet a court-ordered deadline of November 16, 2011 to issue a final Utility MACT, so the agency’s consideration of public comments necessarily will be brief, causing no shortage of concern to the electric generation sector. The following provides a brief discussion of some of the important elements of the proposed Utility MACT as well as an overview of its potential impact on owners and operators of power plants.
