Acres Site RemediationThe McCormick and Baxter Creosoting Company operated wood treating facilities at the Portland, Oregon site from 1944-1991. Four different wood-treating processes were used, involving aromatic oils, heavy metals (arsenic and chromium), and PCP. Waste oils were applied to the site for dust control between 1950 and 1965. Phase I demolition activities were completed prior to this contract.
Wilder excavated, screened, stockpiled, and loaded 33,700 tons RCRA hazardous soil and debris for rail transportation and disposal at Envirosafe Services of Idaho. Wilder was responsible for the transportation and disposal which was under severe time constraints due to the impending land ban restrictions.
More than 32,000 tons of backfill was required to bring the site to grade after completion of the contaminated soil excavation.
Wilder also performed considerable demolition and removal of debris including a large creosoted wood dock, a log loading structure; concrete slabs, equipment pedestals and retaining walls; 4,500 feet of below ground piping; and demolition of an existing office building, laboratory building and a scale house.
Additional work under the contract included lining excavated areas with geotextile; removing and disposing contaminated railroad tracks and ties; and asbestos abatement. A subcontractor hydroseeded the site upon final completion.
