Responsible Byproduct Disposal
FirstEnergy is committed to responsible disposal of materials created as part of the power generation process.
Little Blue Run
The Bruce Mansfield Plant in Shippingport, Pa., was the first coal-fired power plant in North America built with sulfur dioxide (SO2) scrubbers installed as original equipment. Much of the coal combustion byproducts (CCBs) created through the scrubbing process is used to make wallboard at the single-largest CCB recycling facility in the country. Until 2016, the remaining CCBs were stored at a facility known as Little Blue Run. The material is periodically covered with mulch and vegetation, and water quality is monitored through an extensive system. Although scrubber material is no longer placed at the site, FirstEnergy continues to maintain it and manage its closure.
CCB Dry Disposal
Air quality controls at FirstEnergy's coal-fired plants produce synthetic gypsum as a byproduct. This material, identical to gypsum found naturally in the environment, is then transported to state-of-the-art dry disposal facilities. These facilities utilize liners and leachate protection systems as well as extensive groundwater monitoring to ensure environmental protection.
