Environmental Protection Agency
The Environmental Protection Agency (EPA) is proposing to determine that the St. Bernard Parish sulfur dioxide (SO<INF>2</INF>) nonattainment area ("St. Bernard area" or "area") failed to attain the primary 2010 one-hour SO<INF>2</INF> national ambient air quality standard (NAAQS) under the Clean Air Act (CAA or the Act) by the applicable attainment date of October 4, 2018. This proposed determination is based upon review of compliance records for the area's primary SO<INF>2</INF> source, the Rain CII Carbon, LLC (Rain) facility, in addition to dispersion modeling based on the allowable limits showing design values close to the SO<INF>2</INF> NAAQS. If the EPA finalizes this determination as proposed, the State of Louisiana will be required to submit revisions to the Louisiana State Implementation Plan (SIP) that, among other elements, provide for expeditious attainment of the 2010 SO<INF>2</INF> standard.
