The Sandow Steam Electric Station was a 1,137 MW plant until its closure in 2018. Sandow was operated by Vistra Energy, a subsidiary of Luminant in Rockdale, Texas. The AX landfill has been used for ash disposal since May 2015. The AX Landfill is approximately 169 acres in size, as of 2018. Sandow settled with the U.S. Environmental Protection Agency in 2003 due to its violation of the Clean Air Act from updates to Units 1-3. In 2009, Units 1-3 were decommissioned, followed by Units 4-5 in January 2018.
