The Asotin County Regional Landfill (ACRL) is located about 3 miles southwest of the City of Clarkston, Washington in the Clarkston Heights. The landfill occupies approximately 76 acres. In 1975, the ACRL began accepting waste in a 46-acre, unlined area on the western portion of the property. In 1993, this area was closed. Waste filling then transitioned to the modern landfilling area to the east. The active landfill is comprised of four lined cells (Cells A-D). Cell A began filling in 1991, and Cells B and C opened together in 1997. Cell D was opened in 2013. Filling operations are currently occurring in Cell D. Approximately 55,000 tons of municipal solid waste are disposed at the ACRL each year.

The ACRL is proud to serve not only all of Asotin County, but also our waste partners – the City of Pomeroy and Garfield County in Washington, and the City of Lewiston and Nez Perce County in Idaho.
