NRG's Cheswick Generating Station is a 565 MW coal-fired power plant located in Springdale, Pennsylvania, on the Allegheny River. The plant began operating in 1970. Coal ash from the site is currently disposed of at a solid waste landfill, called the Lefever Landfill, and in several on-site impoundments. From 1970 to the late 1990s, the power plant disposed of ash by injecting it into the 6,500-acre Harwick Mine Complex. The Cheswick Generating Station’s Ash Disposal Site, Recycle Pond, and Emergency Pond are regulated under the CCR rule. You can find the industry-reported data here.
