What the agency says

The Environmental Protection Agency (EPA) is proposing to revise a Federal Implementation Plan (FIP) applicable to sulfur dioxide (SO<INF>2</INF>) emissions from several sources located in Billings and Laurel, Montana. Specifically, the EPA is proposing to revise a portion of the FIP promulgated by the EPA in 2008 (2008 Billings/Laurel SO<INF>2</INF> FIP) by removing a provision which contained an affirmative defense for exceedances of flare emission limits during malfunctions, startups, and shutdowns. The EPA is proposing this action pursuant to the Clean Air Act (CAA).
