Environmental Protection Agency August 22, 2014 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing to approve the July 17, 2012, State Implementation Plan (SIP) submission, provided by the South Carolina Department of Health and Environmental Control (SC DHEC) for inclusion into the South Carolina SIP. This proposal pertains to the Clean Air Act (CAA or the Act) infrastructure requirements for the 2008 8-hour ozone national ambient air quality standards (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 2008 8-hour ozone NAAQS is implemented, enforced, and maintained in South Carolina (hereafter referred to as an ``infrastructure SIP submission''). With the exception of provisions pertaining to prevention of significant deterioration (PSD) permitting, interstate transport, and visibility protection requirements, EPA is proposing to determine that South Carolina's infrastructure SIP submission, provided to EPA on July 17, 2012, addresses the required infrastructure elements for the 2008 8- hour ozone NAAQS.

The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the Commonwealth of Virginia pursuant to the Clean Air Act (CAA). Whenever new or revised National Ambient Air Quality Standards (NAAQS) are promulgated, the CAA requires states to submit a plan for the implementation, maintenance, and enforcement of such NAAQS. The plan is required to address basic program elements including, but not limited to, regulatory structure, monitoring, modeling, legal authority, and adequate resources necessary to assure attainment and maintenance of the standards. These elements are referred to as infrastructure requirements. The Commonwealth of Virginia has made a submittal addressing the infrastructure requirements for the 2010 sulfur dioxide (SO2) NAAQS.
