Boise Cascade Mill Site

The Washington State Department of Ecology is asking for public feedback on an interim plan to clean up an old landfill site in Yakima.

The old Yakima city landfill is west of Interstate 82 at 805 N. Seventh St., in the southeast corner of the former Boise Cascade log yard. The city of Yakima plans to remove waste beneath it for new roads being planned near the site.

Yakima’s landfill operated at the site from around 1963 to 1970. Decades later, in 1996, the Department of Transportation began building an off ramp from Interstate 82, with construction uncovering the old landfill.

Inspections have since found pollutants in the soil and groundwater, including diesel and heavy oil. The Yakima Health District conducted a site hazard assessment in 1997 that found lead and chromium in groundwater near the landfill. The site the received the rank of “5” on a hazardous sites list, the lowest level of environmental concern.

The city plans to remove waste from beneath and next to the new roads during construction, test the waste for hazards, and dispose of non-hazardous materials. Any hazardous materials would be sent to an approved off-site facility, according to a notice from Ecology.

Studies then will continue on how to address the remaining contamination in the soil and groundwater.

Additional information about the site is available for review during regular operating hours at the Yakima Central Library downtown or the Washington Department of Ecology at 1250 W. Alder St. in Union Gap, or online at
