  • (a) Determination of Attainment. Effective March 12, 2010 EPA has determined the Baton Rouge 1-hour ozone nonattainment area has attained the 1-hour ozone National Ambient Air Quality Standard (NAAQS). Under the provisions of EPA's Clean Data Policy, this determination suspends the requirements for this area to submit a severe attainment demonstration, a severe reasonable further progress plan, applicable contingency measures plans, and other planning Louisiana State Implementation Plan (SIP) requirements related to attainment of the 1-hour ozone NAAQS for so long as the area continues to attain the 1-hour ozone NAAQS.

    (b) Determination of Attainment. Effective October 12, 2010 EPA has determined that the Baton Rouge 8-hour ozone nonattainment area has attained the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS). Under the provisions of 40 CFR 51.918 this determination suspends the requirements for this area to submit an attainment demonstration, a reasonable further progress plan, applicable contingency measures, and other planning Louisiana State Implementation Plan (SIP) requirements related to attainment of the 1997 8-hour ozone NAAQS for so long as the area continues to attain the 1997 8-hour ozone NAAQS.

    (c) Determination to Terminate the Clean Air Act Section 185 Penalty Fee Requirement. Effective September 6, 2011 EPA has determined that the State of Louisiana is no longer required to submit a section 185 fee program State Implementation Plan (SIP) revision for the Baton Rouge ozone nonattainment area to satisfy anti-backsliding requirements for the 1-hour ozone standard. This determination is based on EPA's determination that the area has attained the 1-hour ozone standard due to permanent and enforceable emissions reductions.

    (d) Redesignation for the 1997 8-hour Ozone Standard. Effective December 30, 2011, EPA has redesignated the Baton Rouge area to attainment for the 1997 8-hour ozone standard. With this final redesignation to attainment for the 1997 8-hour ozone NAAQS and the final determination of attainment for the 1-hour ozone NAAQS in paragraph (a) of this section, the 1-hour anti-backsliding obligations to submit planning SIPs to meet the attainment demonstration and reasonably available control measures requirements, the rate of progress and contingency measures requirements, and any other outstanding 1-hour requirements, cease to apply.

    (e) Clean Data Determination. Effective June 16, 2014 EPA has determined that the Baton Rouge, Louisiana, marginal 2008 8-hour ozone nonattainment area is currently attaining the 2008 8-hour NAAQS for ozone.
