A waterfront site in Anacortes that was used as a mill and box factory, Custom Plywood Mill, has undergone extensive clean-up under the state’s Puget Sound Initiative. Historical operation at the Custom Plywood Mill Site includes lumber and milling practices beginning in the early 1900s. Custom Plywood operated the Site from 1984 until 1991 but all operations ceased following a fire in 1992 Wood waste and chemical contaminants were found in upland soil, groundwater and sediment on the Site, which consists of upland, wetland, intertidal and subtidal in-water areas.

Ecology and the Potential Liable Person (PLP) - GBH Investments LLC - entered into an Agreed Order for site cleanup in March 2008. The Agreed Order required the PLP to develop a Remedial Investigation and Feasibility Study (RI/FS) work plan to evaluate the nature and extent of Site contamination, and RI/FS Report, and a draft Cleanup Action Plan (CAP) for both Upland and in-water Remediation.

A Phase I interim remedial action was completed in the upland area during the summer of 2011. Contaminated soil was removed and disposed of off-site, and a 12,000 square foot wetland mitigation area and vegetated buffer zone were constructed in the upland area. The remaining portion of the Site upland was hydro-seeded with grasses, and a stormwater bio-swale was built along the southern section.

A Phase II interim remedial action was completed in inter-tidal water covering 10 acre during summer/fall of 2013. Marine construction debris and pilings was removed due to the navigational hazards. Marine sediment contaminated with dioxins/furans and wood waste was removed and disposed of off-site. Length of habitat-friendly shoreline was tripled by building new aquatic spit/jetty extension preventing waves from erosion. Wetland built in 2011 is being connected with Fidalgo Bay.
