Proposed No Further Action
City of Portland Bureau of Environmental Services
Water Pollution Control Laboratory (ECSI #2452)
Comments Due: April 1, 2010
Project Location: 6543 N. Burlington Avenue in Portland
Proposal: Pursuant to Oregon Revised Statute, ORS 465.320, and Oregon Administrative Rules, OAR 340-122-100, the Department of Environmental Quality (DEQ) invites public comment on its proposal to issue a no further action (NFA) determination for the City of Portland Bureau of Environmental Services (BES) Water Pollution Control Laboratory (WPCL) site.
Highlights: The WPCL site property is located on the bank of the Willamette River at River Mile 6 within an area of the Willamette River designated by EPA as the Portland Harbor Superfund Study Area. The WPCL facility was constructed in 1997. The site also contains a stormwater quiescent pond associated with City of Portland Outfall (OF) #50.
The WPCL site was developed by 1905 as a flour mill. By 1911 a lumber mill and associated dock structure were constructed along the riverbank. The dock structure was removed by 1961 and by 1977 both buildings had been razed. Demolition debris, dredge material and ash residual from a wood burning electrical generator reportedly were used as fill, including along the river side edge of the site. Black sand fill comprised of spent sand blast grit, reportedly generated from the cleaning of petroleum storage tanks at an off-site location, was imported into the area. The City of Portland purchased the site in 1993. Site development, including bank restoration and
construction of a storm water management system, has mitigated potential exposure pathways to the Willamette River via overland runoff or site-specific, point source stormwater discharges.
Two removal actions have been conducted at the site. In 1993 a release of oil containing polychlorinated biphenyls (PCBs) from an underground electrical line conduit occurred when it was penetrated during an environmental investigation. The conduit appeared related to power management at the former mill. A total of 350 lineal feet of conduit was removed along with 190 cubic yards of soil from two separate areas and disposed off-site in a permitted landfill. The second removal was conducted in 1994 to address imported black sand and other fill. Approximately 1,500 cubic yards of black sand and other fill were excavated and disposed off-site in a permitted landfill.
DEQ reviewed the existing environmental information for the site and concludes that the site currently does not present an unacceptable risk to human health or the environment, and that a NFA determination is warranted for the site.
