Coronado Generating Station Project Description
The Coronado Generating Station is a coal-powered electric generation station in St. Johns, AZ that was constructed in 1979. The Salt River Project utility company owns the station and scheduled it for closure as part of the company’s goal to reduce carbon dioxide emissions. In preparation for this closure, SRP hired Blount Contracting to reclaim an inactive ash slurry settling pond.
Our work included removing and replacing 100,000 CY of blended ash and soil from the pond in a new HDPE-lined burial area. We then covered the material with 51 acres of geomembrane liner to prevent the spread of pollutants. Finally, we placed another 100,000 CY of soil on top of the liner to restore the site with natural vegetation.
