Synopsis:

In a Federal Register (FR) notice published on July 18, 1997 (62 FR 38856), the United States Environmental Protection Agency (EPA) promulgated amendments to the National Ambient Air Quality Standards (NAAQS) for ozone. On Ap ril 30, 2004 (69 FR 23858), the EPA designated and classified a portion of York County, South Carolina within th e Rock Hill Fort Mill Area Transportation Study (RFATS) Metropolitan Planning Organization (MPO) as a moderate nonattainment area for the 8-hour ozone NAAQS as part of the Charlotte-Gast onia-Rock Hill NC-SC Nonattainment Area.

Air quality monitoring data from 2008 to 2010 indicate that all monitors within the Charlotte-GastoniaRock Hill NC-SC Nonattainment Area currently meet the 1997 8-hour ozone NAAQS of 0.08 ppm. As such, the proposed SIP revision would request that the EPA redesignate the York County portion of the

Charlotte-Gastonia-Rock Hill NC-SC Nonattainment Area to attainment for the 1997 8-hour ozone NAAQS and would provide a maintenance plan which fulfills the requirements of Section 175A of the Clean Air Act as amended, that will ensure the area remains in attainment of the 1997 8-hour ozone NAAQS through 2022. Documents relating to this re designation request and maintenance plan will be available via the Department’s website at: http://www.scdhec.gov/environment/baq/MetrolinaSC_Redesignation/
