Determination of Nonattainment and Reclassification of the Beaumont/Port Arthur 8-Hour Ozone Nonattainment Area; State of Texas; Proposed Rule

概要

EPA is proposing to find that the Beaumont/Port Arthur (BPA) marginal 8-hour ozone nonattainment area has failed to attain the 8- hour ozone national ambient air quality standard (NAAQS or standard) by June 15, 2007, the attainment deadline set forth in the Clean Air Act (CAA) and Code of Federal Regulations (CFR) for marginal nonattainment areas. If EPA finalizes this finding, the BPA area will then be reclassified, by operation of law, as a moderate 8-hour ozone nonattainment area. The moderate area attainment date for the BPA area would then be as expeditiously as practicable, but no later than June 15, 2010. Once reclassified, Texas must submit State Implementation Plan (SIP) revisions that meet the 8-hour ozone nonattainment requirements for moderate areas as required by the CAA. In this action, EPA is also proposing the schedule for the State's submittal of the SIP revisions required for moderate areas once the area is reclassified.
