Welcome to the Asotin County Regional Landfill
The landfill comprises approximately 76 acres and is located in the Clarkston Heights. The landfill began in 1975 on the western half of the landfill site. This portion comprises approximately 46 acres and is an unlined landfill area which closed in 1993 as Municipal Solid Waste regulations changed, requiring a liner system, leachate and gas collection systems.
In the eastern portion of the site, three lined areas were constructed per the new regulations (referred to as Cells A, B and C). Cell A began filling in 1991. Cells B & C opened in 1997. A fourth Cell, Cell D, opened in 2014. Cells A, B, C, and D are currently being filled together. The current filling rate is approximately 50,000 tons per year.
