Brunner Island is a 1,490-megawatt power plant owned and operated by Talen Energy in East Manchester Township, York County, Pennsylvania. The Plant burns coal for fuel, but as of 2017, it was adding natural gas-firing capabilities to all three of its units. Brunner Island’s discharges wastewater into the Susquehanna River, which provides drinking water for more than 6 million people and eventually flows into the Chesapeake Bay. The plant's coal-burning operations generate over 671,800 tons of coal combustion residuals (“CCR”)5 annually, which has historically been disposed of in onsite basins and landfills, a system which today includes numerous closed CCR basins, one unlined, active CCR basin (Ash Basin 6), and one active CCR landfill (Disposal Area 8) built on top of a former CCR basin. The NPDES (water pollution discharge) permit for this plant expired in 2006, and the Environmental Integrity Project has submitted three rounds of comments urging the Pennsylvania Department of Environmental Protection to update the permit and pollution controls therein.
