Site Characteristics

General Site Description:
Site History:
Contamination Information: (10/15/1999 ELB/SRS) Chemicals formulated or manufactured at the Rhone-Poulenc (R-P) facility were released to the environment through a variety of means, including spills, leaks, and direct discharges. Prior to 1966, wastewater was discharged directly to Doane Lake. From 1966 until 1975, the wastewater was discharged to the Willamette River. After 1975, wastewater was discharged to the Portland sewer system. R-P began investigating contamination at the site in the early 1980s under DEQ oversight. In October 1983, R-P began pumping and treating contaminated groundwater at the site. In December 1989, R-P entered into a Consent Order with DEQ to conduct a Remedial Investigation and Feasibility Study (RI/FS) at the site. R-P's progress on the investigation, however, was extremely slow. A workplan for conducting the RI/FS wasn't approved until May 1994, and to-date neither the RI/FS nor an associated Risk Assessment has been completed. (11/21/01 ELB/SRP) As a result of these delays, the 1989 order was terminated in February 1998. A new order was signed in July 1999.
Manner and Time of Release: Discharges of untreated wastes on-site and untreated process wastewater off-site to Doane Lake. Spills and on site waste disposal occured on the property and in Doane Lake. Time of release: 1950-1980.
Hazardous Substances/Waste Types: 2,4-D, 2,4,5-T, dioxins and furans, chlorobenzenes, phenolic compounds, creosols, trichloroethene, BTEX, lead, PCBs, herbicides, organochlorine pesticides, heavey metals and arsenic.
Pathways: The site is located in the Doane Lake Study Area (ECSI #36) and the Portland Harbor area (ECSI #2068). The Gould/NL Superfund site (ECSI #49) is adjacent. Surrounding land use is industrial. Groundwater on- and off-site is contaminated, as is surface water and sediment in North Doane Lake. Runoff, surface water, and groundwater discharge to the Willamette River. Groundwater dischrage to North Doane Lake. The Rhone-Poulenc facility was largely demolished in 1992, except for the administrative and storage buildings, foundation slabs, and the wastewater treatment system.
Environmental/Health Threats: Wastewater from the site was historically discharged to West Doane Lake and to the Willamette River. Surface soil, subsurface soil, and groundwater are all contaminated at the site and adjacent properties groundwater and soil. North Doane Lake sediment, fish, and surface water are all contaminated
Status of Investigative or Remedial Action: (10/15/1999 ELB/SRS) In December 1997, DEQ determined that removal of contaminated sediments from East Doane Lake was warranted, and directed R-P to prepare a removal workplan. R-P argued that a removal was unnecessary. DEQ decided that R-P's refusal to conduct the removal, coupled with lack of progress on the RI/FS, demonstrated that R-P was "unwilling" to investigate and clean up the site. DEQ terminated the Consent Order in February 1998 and declared the site an Orphan project in March 1998. DEQ completed the East Doane Lake sediment removal in November 1998, using funds from the Orphan Site Account. R-P will be expected to reimburse DEQ for the removal costs.

DEQ developed a RI workplan in 1999 for completion of the Remedial Investigation (RI). This workplan was attached to a new consent order for the site. Numerous subsequent work plans have been developed and implemented as part of the RI including: Final Groundwater Transport Evaluation Data Needs Report Field Sampling Plan (2/8/02), Remaining Remedial Investigation Work Plan (5/24/02), Draft North Doane Lake Field Sampling Plan (5/7/03), Final NAPL Evaluation Work Plan (5/7/03), Final Post-Characterization Groundwater Monitoring Plan (2/17/04), North Doane Lake Fish Reconnaissance Survey (7/19/04), Outfall 22B Camera Survey Results and Field Sampling Plan (8/16/04), Draft Lake Area Geophysical Survey Report and Intrusive Investigation Work Plan (12/6/04), Draft North Doane Lake Fish Tissue Sampling Work Plan (4/18/04), Final Lake Area Geophysical Survey Report and Intrusive Investigation Work Plan (5/3/05), West Doane Lake Treatability Study Work Plan (6/27/05), Final Stage 1 Source Control Evaluation Work Plan (10/31/05), Final Outfall 22B Interim Remedial Action Measure Work Plan (11/11/05), Draft Lake Area Bioremediation Pilot Study and Colloid Evaluation Work Plan (1/7/06), Winter 2006 Groundwater Monitoring Event Work Plan (6/28/06), Draft Expanded Lake Area Geophysical Survey Work Plan (3/27/06), Draft Lake Area Hydrologic Investigation Work Plan (5/126/06), Draft Summer 2006 Groundwater Monitoring Event Work Plan (6/28/06), Draft Stage 2 Source Control evaluation Work Plan (7/24/06), Draft Spring 2007 Groundwater Monitoring Event Work Plan (4/4/07), Draft Expanded Lake Area Intrusive Investigation Work Plan (8/2/07), Request for Approval, Deep Gravel Hydrogeologic Zone Pumping Test, North Front Avenue Interim Source Control Measure (4/1/08), West Doane Lake Phase 5 Treatability Study Work Plan (7/31/08), Work Plan Storm Sewer Camera Survey Associated with City of Portland Outfall 22B (10/1/08), Draft Outfall 22B Pre-Remedy Investigation Work Plan (4/3/09), Draft Outfall 22B Expanded Interim Remedial Action Measure Work Plan (5/1/09), Final West Doane Lake Interim Remedial Action Measure Work Plan (4/29/10).
Rhone Poulenc has implemented several interim remedial action measures (IRAM): Groundwater Extraction Treatment System (GETS) IRAM (mid 1980s) (shallow herbicide area groundwater extraction system), 1996 Insecticide Area IRAM (caped dust plant area soils), 2004 Facility Structures Assessment and IRAM (decommissioning of shallow infrastructure and capping of herbicide area soil), 2010 City Outfall 22B Expanded IRAM (lining of adjacent site and City storm sewer system), 2010 West Doane Lake IRAM (in-situ stabilization and solidification of West Doane Lake sediments).
