South Carolina Public Service Authority’s Winyah Generating Station is in Georgetown County, SC, along the banks of the Winyah Bay, close in proximity to the Atlantic Ocean. Winyah Generating Station began operations in 1975 and now operates four coal-fired units capable of producing 1,260 MW. The entire facility is planned to be retired by the company by the end of 2027, after its Board required it be retired by the end of 2028 to comply with new regulations, while Units 3 and 4 are scheduled for retirement by the end of 2023. This station also operates four onsite CCR disposal ponds as well as an onsite man-made cooling water pond. Winyah Generating Station’s South Ash Pond, Ash Pond A, Ash Pond B and Slurry Ponds are regulated under the CCR rule.
