Air Plan Approval; South Carolina; Transportation Conformity Update

The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of South Carolina, through the South Carolina Department of Health and Environmental Control, on October 13, 2015. This revision consists of transportation conformity criteria and procedures related to interagency consultation and enforceability of certain transportation-related control measures and mitigation measures. The intended effect of this approval is to update the transportation conformity criteria and procedures in the South Carolina SIP to reorganize previous exhibits into a single Memorandum of Agreement document as well as to update signatories to add the newly established Lowcountry Area Transportation Study to the list of Metropolitan Planning Organizations, created to represent a new urbanized area designated as a result of the 2010 Census. This proposed action is being taken pursuant to the Clean Air Act.
