Yakima County Roads Department will clean woodwaste and soil contaminated with hazardous substances from the Boise Cascade Mill cleanup site, according to a July 1 SEPA filing. The cleanup, labeled an 'Interim Action,' will occur at CSID 12095 and FSID 450 locations near the East-West Corridor Roadway. The work follows a De Minimis Consent Decree under Washington's Model Toxics Control Act.

The public can submit comments on the cleanup plan until July 30. The project, managed by Yakima County Roads Department, does not specify cleanup costs or exact site boundaries in the public filing. The SEPA document notes the cleanup is part of ongoing efforts at the Boise Cascade Mill site, which has been under environmental review for years.

The cleanup aims to address contamination left from the mill's operations. Residents near the East-West Corridor may see temporary construction activity. The county will provide additional details if public feedback requests them, but no specific timeline for the work was included in the filing.
