Site description

Vistra Energy’s Sandow Steam Electric Station was a 1,535-MW plant in Rockdale, Texas in Milam County. The facility was first operational in 1953. 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. The AX landfill has been used for ash disposal since May 2015. The AX Landfill is approximately 169 acres in size, as of 2018.
