Approval and Promulgation of Air Quality Implementation Plans; Louisiana; Determination of Attainment of the 1997 Ozone Standard

摘要

The EPA is proposing to determine that the Baton Rouge, Louisiana moderate 1997 8-hour ozone nonattainment area has attained the 1997 8-hour National Ambient Air Quality Standard (NAAQS) for ozone. This proposed determination is based upon complete, quality assured, certified ambient air monitoring data that show the area has monitored attainment of the 1997 8-hour ozone NAAQS since the 2006-2008 monitoring period, and continues to monitor attainment of the NAAQS based on 2009 data. If this proposed determination is made final, under the provisions of EPA's ozone implementation rule, the requirements for this area to submit an attainment demonstration, a reasonable further progress plan, contingency measures, and other planning State Implementation Plans related to attainment of the 1997 8-hour ozone NAAQS shall be suspended for so long as the area continues to attain the 1997 ozone NAAQS.
