Approval and Promulgation of Implementation Plans; State of Missouri

الملخص

The purpose of this revision to the Missouri State Implementation Plan (SIP) is to incorporate the lead nonattainment areas into the existing new source review (NSR) program. This revision changes the applicability requirements by changing the definition of nonattainment area in the state regulations to include lead nonattainment areas, and to delete the Kansas City area as a nonattainment area in light of its attainment of the ozone standards. This action proposes a limited approval because Missouri has not yet submitted to EPA augmented new source permit rules which meet the amended requirements of part D of title I of the Clean Air Act.
