Approval and Promulgation of State Plan for Designated Facilities and Pollutants: Louisiana; Clean Air Mercury Rule (CAMR)

EPA is taking direct final action to approve the State Plan submitted by Louisiana on October 25, 2006. The plan addresses the requirements of EPA's Clean Air Mercury Rule (CAMR), promulgated on May 18, 2005 and subsequently revised on June 9, 2006. EPA is taking direct final action determining that the submitted State Plan fully implements the CAMR requirements for Louisiana. CAMR requires States to regulate emissions of mercury (Hg) from large coal-fired electric generating units (EGUs). CAMR establishes State budgets for annual EGU Hg emissions and requires States to submit State Plans that ensure that annual EGU Hg emissions will not exceed the applicable State budget. States have the flexibility to choose which control measures to adopt in order to achieve the budgets, including participating in the EPA-administered CAMR cap-and-trade program. In the State Plan that EPA is approving, Louisiana would meet CAMR requirements by participating in the EPA administered cap-and- trade program addressing Hg emissions.
