Summary

Pursuant to the Clean Air Act (the Act or CAA), the Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision, as supplemented, for the St. Bernard Parish, Louisiana 2010 1-hour sulfur dioxide (SO<INF>2</INF>) Primary National Air Quality Standard (NAAQS) nonattainment area. EPA is proposing approval of the following CAA SIP elements: The attainment demonstration for the SO<INF>2</INF> NAAQS, which includes an Agreed Order on Consent (AOC) for the Rain CII Carbon, LLC. (Rain) facility; the reasonable further progress (RFP) plan; the reasonably available control measures (RACM) and reasonably available control technology (RACT) demonstration; the emission inventories; and the contingency measures. The State has demonstrated that its current Nonattainment New Source Review (NNSR) program covers this NAAQS; therefore, no revision to the SIP is required for the NNSR element.
