Site description

The Gibbons Creek Steam Electric Station was a 454-MW power plant operated by the Texas Municipal Power Agency in Carlos, Texas in Grimes County. The facility was purchased in 2021 by Charah Solutions Inc. and imploded in October 2021 as part of a redevelopment plan. The Texas Municipal Power Agency’s website reports the Site F Landfill, Scrubber Sludge Pond, and Ash Ponds to be regulated under the federal coal ash rule. The Scrubber Sludge Pond is 7.4 acres, and the Ash Ponds are three interconnected ponds, each 260 feet wide and 1,800 feet long. All ponds are 20 feet deep and unlined as of January 30, 2018.
