Abstract
§303(d) of the Clean Water Act (CWA) and EPA’s Water Quality Planning and Management Regulations require states to develop total maximum daily loads (TMDLs) for water bodies that are included on the §303(d) list of impaired waters. A TMDL is the maximum amount of pollutant a waterbody can assimilate while meeting water quality standards (WQS) for the pollutant of concern. All TMDLs include a waste load allocation (WLA) for any National Pollutant Discharge Elimination System (NPDES) permitted dischargers, a load allocation (LA) for all nonpoint sources, and an explicit and/or implicit margin of safety (MOS). This technical report describes the development of fecal coliform (FC) TMDL for impaired shellfish station 12B-53, and Enterococci TMDLs for impaired recreational stations MD-120, RT-07055, and RT-20236 in Dawho River in Charleston County, South Carolina. These stations have been included in South Carolina’s 2020 and 2022 303(d) list of impaired waters for exceeding FC and Enterococci WQS for shellfish harvesting and recreational uses.
