NV Energy — Reid Gardner Power Station


View Larger Map

Readers Note: This webpage provides information about ongoing remediation activities at the Reid Gardner Power Station in Southern Nevada. Information about "appeals" related to the power station are posted on the State Environmental Commissions Website — look under "Appeal Hearings".

Reid Gardner is 4 unit 557 MW coal fired power plant located on 480 acres in Moapa Valley, Nevada. The station is located just 4 miles west of Glendale and 60 miles northeast of Las Vegas. NV Energy operates the Reid Gardner Generating Facility.

The Muddy River crosses the site, as does the Union Pacific Railroad's Las Vegas -Salt Lake City line. The plant is surrounded by BLM land to the north and south, Paiute agricultural land and residences on the west, and an inactive dairy farm on the east. The first unit was placed in service in 1965 and the fourth unit came online in 1983.

Remediation Activities:

The Reid Gardner Generating Station process water, which has been recycled and used beyond the treatable limits, is routed to evaporation ponds. Historically, some of these ponds did not include engineered liners and have impacted shallow groundwater at the Station. Currently, all active evaporation ponds are high density polyethylene (HDPE) double-lined with an inner leak-detection and collection system to protect groundwater. There are no surface water discharges of wastewater from the Station as the plant is a Zero Liquid Discharge facility.

NV Energy has begun cleaning out and closing the historic ponds. Pond solids have already been removed from three ponds (Ponds D, F and G) of the 11 ponds that are in the Muddy River flood plain [MAP]. Solids will be removed from Ponds 4A, 4C1 and 4C2 in 2014-2015. Solids removal from Ponds 4B1, 4B-2, 4B-3, E-1, and E-2 will occur after the ponds are taken out of service in the next five years. Other remediation measures implemented to address groundwater contamination from the ponds include construction and operation of an interim groundwater collection system south of former Pond D and Ponds E-1 and E-2.

Diesel fuel discovered floating on groundwater in one area of the site is likely due to a release from former underground diesel-fuel piping. A diesel recovery system has been in operation since 1988 and was upgraded in 2003 and again in 2013. The diesel recovery system, which recovers free product and contaminated groundwater, continues to operate in the northeastern portion (power generation area) of the site.

NV Energy and the NDEP entered into an Administrative Order on Consent (AOC) for the Site on February 22, 2008. The AOC calls for NV Energy to continue with environmental contaminant characterization activities and for the identification of clean-up measures for the soil and groundwater at the site. The AOC also calls for the implementation and long-term operation and maintenance of NDEP-approved clean-up measures.

In addition to the groundwater impacts associated with the on-site ponds and diesel fuel piping, various other potential areas of soil and/or groundwater contamination have been identified. These areas will also be addressed through implementation of the AOC. These efforts may include sampling soil and groundwater to characterize potential site contamination and then, as appropriate, implementing NDEP-approved clean-up activities.

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.
