What the agency says

The Environmental Protection Agency (EPA) is proposing to approve Louisiana's State Implementation Plan (SIP) revision submitted to EPA on April 2, 2025, for the Evangeline Parish 2010 1-hour sulfur dioxide (SO<INF>2</INF>) primary national ambient air quality standard (NAAQS) nonattainment area. EPA is proposing approval of the following Clean Air Act (CAA) SIP elements: The attainment demonstration for the SO<INF>2</INF> NAAQS, which includes an Agreed Order on Consent (AOC) for the Cabot Corporation's Ville Platte Plant (Cabot) 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.
