## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve the portions of the State Implementation Plan (SIP) submission, submitted by the State of South Carolina, through the South Carolina Department of Health and Environmental Control (SC DHEC), on May 8, 2014, for inclusion into the South Carolina SIP. This final action pertains to the infrastructure requirements of the Clean Air Act (CAA or Act) for the 2010 1-hour sulfur dioxide (SO<INF>2</INF>) national ambient air quality standard (NAAQS). The CAA requires that each state adopt and submit a SIP for the implementation, maintenance and enforcement of each NAAQS promulgated by EPA, which is commonly referred to as an "infrastructure SIP submission." SC DHEC certified that the South Carolina SIP contains provisions that ensure the 2010 1- hour SO<INF>2</INF> NAAQS is implemented, enforced, and maintained in South Carolina. EPA has determined that portions of South Carolina's infrastructure SIP submission, provided to EPA on May 8, 2014, satisfy certain required infrastructure elements for the 2010 1-hour SO<INF>2</INF> NAAQS.
