Summary

The Environmental Protection Agency (EPA) is proposing to approve 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 December 18, 2015, to demonstrate that the State meets the infrastructure requirements of the Clean Air Act (CAA or Act) for the 2012 Annual Fine Particulate Matter (PM<INF>2.5</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. SC DHEC certified that the South Carolina SIP contains provisions that ensure the 2012 Annual PM<INF>2.5</INF> NAAQS is implemented, enforced, and maintained in South Carolina. EPA is proposing to determine that portions of South Carolina's infrastructure submission, submitted to EPA on December 18, 2015, satisfy certain required infrastructure elements for the 2012 Annual PM<INF>2.5</INF> NAAQS.
