Site description

Reid Gardner Generating Station was a 612 MW coal-fired power plant located near Moapa, Nevada on the Muddy River. The station began operating in 1965 and retired in 2017. According to a 2013 report by NV Energy, past on-site spills, unlined and clay-lined wastewater and ash ponds, and a former diesel fuel delivery system were the primary sources of shallow groundwater contamination at the site. Groundwater at the site has been monitored for more than 35 years at over 100 monitoring wells.

Reid Gardner Generating Station is listed among the U.S. Environmental Protection Agency's list of proven damage cases, indicating that operations at the site have contaminated ground or surface water above drinking water standards and health advisories. This station’s Mesa Ash Landfill and M5/M7 Surface Impoundments are regulated under the CCR-rule. You can find the industry reported data here.
