The great majority of the ash generated by the Station was disposed of dry in the Mesa Landfill. Ash management approaches used over the years of plant operation included placement in ash settling ponds, use of ash as structural fill in select locations, and disposal in the onsite landfill.

Operations at the former Station generated waste products including fly ash, bottom ash, and process water effluent. Characterization and Remediation Activities: One warehouse, with office space, was also preserved for continuing use by NV Energy staff for onsite operations and site remediation purposes. The plant’s electrical substation was preserved for use in NV Energy’s transmission system. In total, greater than 95% of the demolished materials were recycled or reused. General construction and demolition debris was disposed in the existing Mesa Landfill in accordance with the current Class III industrial waste permit. Concrete foundations were broken up, rebar removed for recycling, crushed and used to backfill excavations in the center of the site. Other materials such as rolling stock, transformers, steel, and aluminum were either sold for reuse or recycled by the demolition contractor. This work included identification, removal, and offsite disposal (in accordance with State and Federal regulations) of Universal Wastes, PCB containing materials, and asbestos containing materials (ACM). Decommissioning and demolition of the Station was completed in July 2020.ĭecommissioning and demolition activities included the removal of coal stockpiles, buildings, stacks, rolling stock, utilities, scrap materials, subsurface structures, and structural foundations to a depth of at least 6 feet below ground surface. Permanent shut down of Units 1, 2 and 3 occurred on Decemand Mafor Unit 4.

Potential environmental contaminants identified at the site include, but are not limited to, total dissolved solids (TDS), sulfate, chloride, metals, volatile organic compounds (VOCs), and petroleum hydrocarbons. The AOC also calls for long-term operation and maintenance of NDEP-approved clean-up measures. The AOC calls for NV Energy to continue with environmental contaminant characterization activities, including identification of clean-up measures for the soil and groundwater at the site and implementation of these clean-up measures.

NV Energy and the Nevada Division of Environmental Protection (NDEP) entered into an Administrative Order on Consent (AOC) for the Reid Gardner Station (Station) on February 22, 2008. As of July 2020, the Reid Gardner Station is no longer actively producing electricity and all power-generating facilities have been decommissioned and demolished.
