This rule finalizes EPA's finding of nonattainment and reclassification of the Beaumont/Port Arthur 8-hour ozone nonattainment area (BPA area). EPA finds that the BPA 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. As a result, on the effective date of this rule, the BPA area is reclassified by operation of law as a moderate 8-hour ozone nonattainment area. The new moderate area attainment date for the reclassified BPA area is "as expeditiously as practicable," but no later than June 15, 2010. The State of Texas must submit a SIP revision that meets the requirements of the CAA on or before January 1, 2009.
