|General Site Description:||
The Mar Com North Site is located along the east bank of the Willamette River in Portland just north of Cathedral Park and just south of the Port of Portland Terminal 4. Starting in 1905, the current Mar Com North parcel had been used for storage of materials related industrial activities that included a sawmill operation and ship construction and repair, which occurred on the current adjacent South Parcel until activities ceased in 2004. DEQ and the former Mar Com owners conducted several environmental investigations on the entire Mar Com site. In 2003, DEQ separated the Mar Com site into the North and South Parcels based on the phasing of the site investigation, historical land use, and the Port’s desire to acquire the North Parcel. DEQ finished the Remedial Investigation (RI) and Risk Assessment for the North Parcel and proposed a Source Control Decision (SCD) in December 2003. The Remedial Investigation at the South Parcel is ongoing.
DEQ prepared a Record of Decision for the North Parcel in 2004. The ROD delineated the North Parcel Site to include the land above ordinary high mark water and the upland portion of the North Parcel. The beach area below the ordinary high water mark was designated to be part of the Locality of Facility for the South Parcel because of the historical operations and the conceptual site model for the site. DEQ concluded that contaminant concentrations in beach sediments and near-shore, in-water sediments are not likely from uplands sources on the Mar Com North Parcel, because elevated contaminant concentrations were not detected in upland soils and shallow groundwater. EPA’s Source Control Comment letter of January 23, 2004 supported DEQ’s conclusion that the North Parcel did not appear to be a current source of hazardous substances to the river. City of Portland OF-52A discharges onto the beach and is being addressed under the City Outfall Project and the South Parcel investigation.
After conducting additional pre-acquisition environmental site assessments on the North Parcel, the Port acquired the various properties comprising the North Parcel from Mar Com as a non-liable purchaser under the Consent Judgment. Under the Consent Judgment, the Port agreed to implement the Remedial Action Work specified in the ROD and defined in the Consent Judgment.
|Manner and Time of Release:|
|Hazardous Substances/Waste Types:|
|Status of Investigative or Remedial Action:||Mar Com completed collection of RI data for the north parcel and DEQ conducted a risk screening evaluation. Unacceptable risks (human health) were attributed to piles of lead and arsenic contaminated sandblast grit disposed of on the North Parcel and a small area of barium and chromium contaminated soil. DEQ issued a staff report in January 2004 recommending removal and disposal of the sandblast grit. Public notice followed in February 2004. Comments from EPA agreed with DEQ's proposed remedy. City of Portland BES comments concerned a city outfall to the beach along the north parcel. The Port of Portland entered into a Prospective Purchaser Agreement with DEQ and obtained the north parcel. The Port removed 278 cubic yards of contaminated soil and sandblast grit in accordance with the ROD, thereby completing the site cleanup.|
