Site Characteristics

General Site Description: [5/30/17 VCP/SAM] DEQ proposes to enter into a consent judgment with Metro Metals Northwest, Inc. The Consent Judgment outlines DEQ's oversight of remedial design and cleanup of East Whitaker Pond sediments and adjacent soil and wildlife habitat improvement.

The consent judgment also includes settlement of Metro Metals' potential liability for contribution to sediment contamination in the Columbia Slough and satisfaction of liability associated with State of Oregon natural resource damages to Whitaker Ponds and the Columbia Slough.

The selected remedial action consists of the following elements:
- Excavation of sediment and soils with relatively higher concentrations of contaminants of concern.
- Placement of activated carbon in areas with moderate PCB concentrations.
- Placement of a thin-layer of clean substrate to enhance natural recovery in peripheral areas
- Effectiveness Monitoring.
Site History: [7/14/11 SAM/SA] This site was used for agricultural purposes until about 1990 when Riedel Environmental Services developed a processing and composting facility. MetroMetals, a scrap metal recycling facility, has operated on the site since 1992 and aquired the adjacent Coast Crane parcel(ECSI#1225) in 2006.
Contamination Information: Metals
Manner and Time of Release:
Hazardous Substances/Waste Types: [6/18/13 SAM/ICP] Metals and PCBs
Pathways: [12/9/10 SAM/SA] Metro Metals discharges stormwater to the East Whitaker Ponds. High metal concentrations were found during routine stormwater sampling for their stormwater permit. In 2008 Metro Metals installed a stormwater treatment system, which appears to be working as designed based on COLS-1200 permit data, but sediments near the former discharge may contain elevated levels of metals or other pollutants from historic stormwater runoff.
Environmental/Health Threats:
Status of Investigative or Remedial Action: [5/23/11 SAM/SA] Metro Metals submitted work plan to evaluate sediments near outfall in East Whitaker Pond.
[7/12/11 SAM/ICP] DEQ approved work plan to evaluate sediments near outfall in East Whitaker Pond. This stormwater work plan also covers the former Coast Crane parcel ECSI #1225.

[11/23/11 SAM/VCP] Metro Metals submitted data from sediment evaluation. The historical outfall(OF3) data indicates significant concentrations of metals and PCBs at the surface(0-10cm) and appears to decrease at depth(30cm). Next steps will evaluate extent of metals and PCBs.

[12/6/12 SAM/VCP] Evaluation of extent of metals and PCBs in sediments underway. Metals appear to decrease with distance from outfall, however PCBs are still at concentrations of concern and additional sampling is planned.

[4/30/2014 SAM/VCP] A streamlined Feasibility Study will be prepared to assess potential remedial actions for the contaminated sediment.

[7/28/15 SAM/VCP] Metro Metals submitted a Revised Feasibility Study on February 5, 2015. The proposed alternative includes Partial Removal, Enhanced Monitored Natural Recovery, and Activated Carbon Amendment in selected areas East Whitaker Pond.

[11/3/15 SAM/VCP] DEQ is proposing cleanup action for East Whitaker Pond. The proposed remedial action includes a combination of soil removal, dredging of contaminated sediments and placing a thin layer of clean material across the majority of the pond. In some locations, the clean material will include an activated carbon amendment. Confirmation sampling and long-term monitoring is proposed to evaluate the effectiveness.

[2/1/16 SAM/VCP]
Record of Deicsion(ROD) Completed 1/29/16. The selected remedial action consists of the following elements:
• Excavation of sediment and soils with relatively higher concentrations of contaminants of concern.
• Placement of activated carbon in areas with moderate PCB concentrations.
• Placement of a thin-layer of clean substrate to enhance natural recovery in peripheral areas
• Effectiveness Monitoring.
Based on public input, the remedy was expanded to include addtional evaluation of sensitive species, clarification of removal extent and activated carbon placement.

[6/8/16 SAM/VCP] DEQ currently negotiating a Consent Judgment with Metro Metals to continue with the remedial design and action phase of the project.

[11/8/17 SAM/VCP] DEQ entered into a consent judgment with Metro Metals Northwest, Inc on October 5, 2017. The Consent Judgment outlines DEQ’s oversight of remedial design and cleanup of East Whitaker Pond sediments and adjacent soil and wildlife habitat improvement.

The consent judgment also includes settlement of Metro Metals’ potential liability for contribution to sediment contamination in the Columbia Slough and satisfaction of liability associated with State of Oregon natural resource damages to Whitaker Ponds and the Columbia Slough.
