40 CFR Part 52

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

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing to approve 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).

DATES: Written comments must be received on or before January 8, 2007.
