Pasco Landfill NPL Site

Draft cleanup option reports

September 12, 2018 - October 26, 2018

The Industrial Waste Area Group III and the Landfill Group, which represent the majority of the potentially liable persons responsible for Pasco Landfill cleanup, have each submitted a draft Focused Feasibility Study (FFS) to the Washington State Department of Ecology (Ecology) evaluating final cleanup options for all the landfill zones.
The public is invited to comment on the draft FFS reports to provide input on final cleanup for each waste area. We will use information from the FFS reports, along with all interim cleanup actions and public input, to write the final cleanup plan for the Pasco Landfill. This plan will be available for public comment before becoming final.
The Pasco Landfill is about 1.5 miles northeast of the City of Pasco, north of the intersection of Kahlotus Road with U.S. Highway 12. The landfill property covers nearly 250 acres and is surrounded by agriculture and commercial businesses. The Basin Disposal transfer station on Dietrich Road is at the southern end of the landfill. The landfill no longer accepts waste and is closed to the public. Gates, fencing, and signs restrict access to this active cleanup site. 

The landfill opened in 1958. Waste was burned in trenches until 1971, when the site became a sanitary landfill. From 1972 to 1975, the landfill accepted industrial waste. Some was delivered in 55-gallon drums and disposed in two zones. The rest was delivered as bulk liquids that were placed into large evaporation lagoons. The landfill closed in 2001.
