Summary Information
(last updated on: 11/7/2017 7:42:09 AM)
The 27-acre site, now vacant, is located at approximately river mile 6.8 (east) bordering the Portland Harbor Superfund site. With approximately 3,000 feet of river shoreline, the site was used extensively for industrial activity from the early 1900s to 1970s, including a cooperage, lumber mill, and dry dock activities. Significant over-water activity occurred. METRO, a tri-county governmental agency, currently owns the property. Extensive environmental investigation has been completed at the site including surface and subsurface soil, groundwater, and sediment in adjoining river sediment. Contaminants including dioxins, PCBs, metals, and petroleum hydrocarbons have been detected, most notably in upland soil and river sediment. In addition to remedial investigation work, both human and ecological risk assessments have been completed (2014); a feasibility study was begun in 2014 to identify cleanup activities for the upland site that would eliminate risk to human health or the environment. This work is continuing. Remedies under consideration include soil removal and capping. A plan for removal of highly-concentrated contaminanted soil in the upland property has been approved by DEQ, with removal slated for June or July 2015 pending permit approval from the City of Portland. Removal would focus on elevated dioxins, but also address metals and PCBs. Excavated soil will be transferred to covered trucks and transported to a solid waste landfill. Measures will be taken during removal to ensure that off-site transport of contaminated soil does not impact local neighborhoods. Removal work was completed in 2016. An updated upland feasibility study and source control evaluation was submitted to DEQ in October 2017 and is currently under review. At this time, environmental work in the site upland is being overseen by DEQ under the Northwest Region Cleanup Program located in Portland. Actions to address in-water contamination (Willamette River) adjacent to the site are being overseen by EPA Region 10 (Seattle) and will be implemented after remedy selection is completed for the Portland Harbor Superfund site. Both DEQ and the Oregon Health Authority have advised persons to not enter the site for recreational or other purposes given the presence of soil and sediment (river) contamination.
