Reid Gardner Generating Station was a 612-MW coal-fired power plant located near Moapa, Nevada on the Muddy River in Clark County. 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. This station’s Mesa Ash Landfill and M5/M7 Surface Impoundments are regulated under the CCR-rule.
