Approval and Promulgation of Implementation Plans; South Carolina: Revisions to State Implementation Plan

Короткий зміст

EPA is approving several revisions to the South Carolina State Implementation Plan (SIP), submitted by the South Carolina Department of Health and Environmental Control (SC DHEC) on April 13, 2005, and October 24, 2005. Both revisions include modifications to South Carolina's Regulation 61-62.1 "Definitions and General Requirements." In the April 13, 2005, submission, Regulation 61-62.1 is being amended to be consistent with the new Federal emissions reporting requirements, referred to as the Consolidated Emissions Reporting Rule (CERR), and to streamline the existing emissions inventory requirements. SC DHEC is taking an action that is consistent with the final rule, published on June 10, 2002 (67 FR 39602). The October 24, 2005 submittal revises the definition of Volatile Organic Compounds (VOC). The revision adds several compounds to the list of compounds excluded from the definition of VOC on the basis that they make a negligible contribution to ozone formation, and similarly removes several compounds from the definition of VOC. This action is being taken pursuant to section 110 of the Clean Air Act (CAA).
