PFAS - Shaw Air Force Base
In January - March 2020, DHEC sampled and analyzed community drinking water wells near Shaw Air Force Base (AFB) in Sumter, South Carolina for per- and polyfluoroalkyl substances (PFAS). The focus area for sampling was approximately a three (3) miles radius surrounding the Base property boundary within which 13 community water systems were sampled. Shaw AFB is one of the, Department of Defense sites, where PFAS were known to be used for training with fire-fighting foam. Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) are the two most commonly-produced and studied of the PFAS group. In 2016, the US Environmental Protection Agency (USEPA) issued a drinking water Lifetime Health Advisory (LHA) of 70 parts per trillion (ppt) for PFOA and PFOS, either individually or…, in this table, . Accumulated water quality data for the SAFB investigation graphic Exceedances of the USEPA LHA were observed at four of the 13 systems. Three of these were mobile home parks; the fourth was a business. Routine chemical analyses of the mobile home parks’ water wells and sanitary surveys of the mobile home parks’ water systems were performed. As a part of the Department’s community engagement…, Crescent Mobile Home Park Information Packet, American Mobile Home Plaza Information Packet, Cedar Hill Mobile Home Park Information Packet, We also answered questions residents had about their drinking water, including steps to mitigate or reduce potential exposure. The water systems that did not have exceedances of the USEPA LHA were encouraged to share their results with their customers and to enhance their knowledge and understanding of PFAS compounds as related to their systems. , *Page last updated 8/07/2020 at 10:34 AM.Moho em Recintos Fechados (Español)

Because South Carolina's Coastal Zone Management Program (CZMP) is federally-approved, a number of Federal Agency activities and permits are required to comply with the enforceable policies of the state's approved coastal management program. This "Federal Consistency" authority resides under the, Federal Coastal Zone Management Act (FCZMA), which was enacted on October 27, 1972, to encourage coastal states to develop comprehensive programs to manage and balance competing uses of and impacts to state's coastal resources or the uses of them.

By definition an MS4 is a system of conveyances that include, but are not limited to, catch basins, curbs, gutters, ditches, man-made channels, pipes, tunnels, and/or storm drains that discharge into, Waters of the State, . For these conveyances or system of conveyances to be recognized as an MS4, a state, city, town, village, or other public entity must own them. These conveyances must also not be part of a Publicly Owned Treatment Works and may not operate as a combined sewer. Operators of large, medium and regulated small Municipal Separate Storm Sewer Systems are required to obtain, NPDES permit coverage, in order to discharge pollutants into Waters of the State. These designations (large, medium, and small) are based on urbanized areas as determined by the latest census. South Carolina has one (1) large MS4 - the South Carolina Department of Transportation and three (3) medium MS4s -, City of Columbia, Greenville County, and Richland County., These MS4s receive individual NPDES permits for their discharges. There are also over, 70 regulated small MS4s, in South Carolina. The operators of these may choose to receive coverage under a general permit or obtain individual permit coverage.

Only 2 times the footprint is to be cleared as the lots are developed. The assumed disturbance on each lot is _____ sq. ft."
