CCW Impoundment Assessment Report. Bruce Mansfield Power Plant, Beaver County, Pennsylvania

摘要

The Bruce Mansfield plant is a coal-fired power plant located on the south bank of the Ohio River in Shippingport, Beaver County, Pennsylvania-owned and operated by First Energy Generation Corporation (First Energy). A Site Vicinity map is shown on Figure 1-1, and an aerial photograph of the plant is shown on Figure 1-2. Under normal operating conditions, byproducts of coal combustion, including fly ash, bottom ash, boiler slag, flue gas emission control residuals, and other general wastewater products, are sluiced or trucked into several storage basins east of the plant. The impoundments include a North Low Dissolved Solids Pond (North LDS), a South Low Dissolved Solids Pond (South LDS), and a West High Dissolved Solids Pond (West HDS). An East High Dissolved Solids pond exists at the Site as well, but it was decommissioned in 2003. These ponds are shown on the aerial photograph provided on Figure 1-3. A plan view and typical sections for these impoundments are included on Figures 1-4 and 1-5, respectively. In addition, fly ash and other generation byproducts are pumped seven miles away to the Little Blue Run Dam and Reservoir for permanent disposal. The Little Blue Run impoundment is not addressed in this report.
