According to the South Carolina Department of Health and Environmental Control (SCDHEC), 503 of the state’s 3,693 active pollution control permits have expired. Most of the expired permits are for water and air discharges. The agency’s director Catherine Templeton has said that SCDHEC will work to expedite review of replacement permits. Until they are reissued, expired permits normally remain in effect. If SCDHEC adapts its permitting priorities to place increased attention on reissuing expired permits, consideration of applications for new permits could be delayed.
