On April 19, 2013, the Ohio Environmental Protection Agency (Ohio EPA), submitted a request to EPA to make a determination under the Clean Air Act (CAA) that the Bellefontaine nonattainment area has attained the 2008 lead (Pb) national ambient air quality standards (NAAQS or standard). In this action, EPA is determining that the Bellefontaine nonattainment area (hereafter also referred to as the "Bellefontaine area" or "area") has attained the 2008 Pb NAAQS. This determination of attainment is based upon complete, quality- assured and certified ambient air monitoring data for the 2010-2012 design period showing that the area has monitored attainment of the 2008 Pb NAAQS. Additionally, as a result of this determination, EPA is suspending the requirements for the area to submit an attainment demonstration, together with reasonably available control measures (RACM), a reasonable further progress (RFP) plan, and contingency measures for failure to meet RFP and attainment deadlines for as long as the area continues to attain the 2008 Pb NAAQS.
