Air Plan Approval; SC; VOC Definition

The Environmental Protection Agency (EPA) is taking final action to approve a revision to the South Carolina State Implementation Plan (SIP). The revision makes a modification to the definition of ``volatile organic compounds'' (VOC). EPA is approving the SIP revision submitted by the State of South Carolina, through the South Carolina Department of Health and Environmental Control (DHEC) on September 5, 2017, because the State has demonstrated that these changes are consistent with the Clean Air Act (CAA or Act).
