Site description

First Energy Corporation’s W.H. Sammis Power Plant is located in Jefferson County, OH, along the banks of the Ohio River. Plant Sammis began operations in 1959 and currently operates seven coal fired units and five oil-fired peaking units that combine to produce 2,233 MW. This plant burns 18,000 tons of coal daily, amount to an annual average of 6.6 million tons of coal burned annually. All of the CCR material that is generated by this plant are stored in one of three active disposal sites. First Energy Corporation is planning to close down Plant Sammis in 2022. Plant Sammis’ three disposal sites, Pond 1, Pond 2 and Hollow Rock Facility, are regulated under the CCR-rule. You can find the industry reported data here.
