Abstract
EPA is granting full approval of Missouri's attainment demonstration State Implementation Plan (SIP) and control strategy for the lead National Ambient Air Quality Standard (NAAQS) nonattainment area of Herculaneum, Missouri. This action is based on a proposed conditional approval of the SIP published on October 8, 2008, and a proposed approval of the supplemental SIP submittal received by EPA on September 3, 2009, published in the Federal Register on August 27, 2010. The applicable standard addressed in this action is the lead NAAQS promulgated by EPA in 1978. EPA has determined that both SIP submittals from the State of Missouri satisfy the applicable requirements of the Clean Air Act (CAA or Act) and demonstrates attainment of the 1.5 microgram per cubic meter ([mu]g/m\3\) lead NAAQS in the Herculaneum, Missouri area. This action does not address the obligations which Missouri has relative to the revised lead NAAQS promulgated by EPA in 2008.
