(k) EPA is conditionally approving two West Virginia State Implementation Plan (SIP) revisions submitted on July 1, 2014 and June 6, 2012 relating to revisions to 45CSR14 (Permits for Construction and Major Modification of Major Stationary Sources of Air Pollution for the Prevention of Significant Deterioration) for failure to include a significant monitoring concentration value (SMC) of zero micrograms per cubic meter for fine particulate matter (PM2.5). The conditional approval is based upon a commitment from the State to submit an additional SIP revision with a revised regulation at 45CSR14-16.7.c which will incorporate a SMC value of zero micrograms per cubic meter for PM2.5 to address this discrepancy and to be consistent with federal requirements. If the State fails to meet its commitment by June 24, 2016, the approval is treated as a disapproval. Sec. Sec. 52.2523-52.2524 [Reserved]
