## Abstract

The EPA is approving a State Implementation Plan (SIP) revision submitted by the State of Louisiana for the Baton Rouge ozone non-attainment area for the purpose of replacing the previously approved contingency measures in the Demonstration of Attainment. These replacement measures meet the requirements in sections 172(c)(9) and 182(c)(9) of the Clean Air Act (the Act) as amended in 1990. We are approving replacement of the State's current contingency measures with contingency measures that require emission reductions from the Trunkline Gas Company--Patterson Compressor Station in St. Mary Parish. The State's current contingency measure requirement is that it hold 5.7 tons per day (tpd) of VOC emission reductions "on deposit" in the State of Louisiana Emission Reduction Credit Bank (ERC Bank). The replacement contingency measure that the EPA is approving would require that the Trunkline facility permanently reduce its volatile organic compound (VOC) emissions by 6.1 tpd from 1990 emission levels. These reductions are surplus and federally enforceable. Pursuant to section 553(d) of the Administrative Procedure Act, EPA finds good cause to make this action effective immediately.
