This request is based on the monitoring data for the BRNA that shows a design value of 0.075 ppm or 75 ppb as of December 31, 2013. The Department attributes the realized reductions and air quality improvements to permanent and enforceable control measures. Section 107(d)(3)(E) of the 1990 Clean Air Act Amendments (CAAA) states that an area can be redesignated to attainment if all the following conditions are met: • The EPA has determined that the NAAQS have been attained. • The applicable implementation plan has been fully approved by the EPA under Section 110(k). • The EPA has determined
