Site Description

The Taylor Lumber and Treating site is located west of the City of Sheridan, Oregon. Located alongside the Yamhill River, the area surrounding the site includes commercial/industrial properties and some residences. Taylor Lumber operated a saw mill and wood-treating facility at the site until 2001 when the company entered into bankruptcy. The facility had numerous releases and spills of wood-treating chemicals during its operations, leading to the contamination of the soil, ground water, and drainage ditches in and around the facility. Pacific Wood Preserving of Oregon (PWPO) entered into a Prospective Purchaser Agreement with EPA and purchased the wood-treating portion of Taylor's property (approximately 37 acres). PWPO began wood-treating operations in June 2002, and continues to operate the site today using chemicals that are safer for their employees and for the environment.

Current Site Status and Cleanup Actions to Date

  • Between 1999 and 2005, EPA removed 4,200 tons of contaminated soil from ditches around the facility to keep it from washing into the South Yamhill River. In the main treatment plant area, EPA built an underground barrier wall to contain the most contaminated portion of the site and keep the groundwater from moving off the property.
  • In 2001, the site was added to the EPA's National Priorities List (NPL).
  • In 2005, EPA completed a remedial investigation and feasibility study (RI/FS) and issued the Record of Decision (ROD) to address wood-treating chemicals and wastes at the site. In 2006, EPA completed the final remedial design.
  • EPA initiated the final remedial action at the site in 2007. Areas that were excavated were backfilled with clean material and compacted to support equipment loads by the site owner (PWPO). Seventeen monitoring wells were abandoned and nine wells were altered.
  • In September 2007, EPA started an emergency removal action to remove newly discovered creosote contamination in a drainage ditch flowing to the South Yamhill River. Removal of this material is on hold pending dry weather but is expected to be completed by spring 2008.

Current Funding Status

  • In Fiscal Year 2007, EPA obligated $1.1 million for new onsite soil removal work.

Key Accomplishments

  • In November 2004, EPA excavated approximately 510 tons of contaminated soil and materials at a residence located directly east of the former facility.

  • From April to October 2007, EPA implemented the remedial action selected in 2005.

  • During September 2007, EPA initiated an emergency removal action, which is scheduled to be completed in 2008.
