Site Characteristics

General Site Description:
Site History:
Contamination Information: (10/29/92 KPD/SAS) There are four areas where actual or potential releases have occurred. First is a wastewater treatment facility, located across the Willamette River from the main site. Treated wastewater, containing trace amounts of TCE, and phenol-formaldehyde resin, is discharged into the river. Sludge is sprayed onto two acres of adjacent fields. The discharges are regulated by a NPDES permit, and the facility itself is a registered hazardous-waste generator. Second, in 1978, 1,400 gallons of TCE spilled on-site. Soils in the spill area tested from 1,000 to 10,000 ppm TCE, while groundwater tested up to 254 ppm TCE. A hazardous waste permit to manage the spill as a landfill was issued under RCRA in 1985. Contaminated soil has since been removed and disposed of at Arlington, and the spill area paved over and used as a parking lot. Groundwater is still contaminated. Third, prior to 1972, pulp/paper wastes were discharged into a lagoon on-site under an NPDES permit. The lagoon was filled during construction of an administration building, and it is unknown whether any hazardous materials were left in place. Finally, mineral spirits were stored in a 10,000-gallon underground storage tank (UST). Mineral spirits were encountered in soils between the UST and the Willamette River during excavation for a city water line. It is not known if the contaminated soils were cleaned up.

(10/01/07 SJS/SRS) Note - discharge of phenol-formaldehyde resin ceased in 2003 when the hardboard facility was shut down.

(3/3/10 SJS/SRS) Cleanup activities concentrate on the significant quantity of TCE (and decay products) present near and underneath the former TCE process area. No other significant contamination is known at the site.
Manner and Time of Release: (9/4/07 SJS/SRS) Origin of 1978 spill is believed to be a valve left open to newly installed carbon beds. Additional contamination may have resulted from past operating practices.
Hazardous Substances/Waste Types: Trichloroethylene
Pathways: The site is located at the confluence of the Willamette and Marys Rivers in Corvallis. Groundwater contaminated with TCE has reached the Willamette River, but concentrations do not pose a risk to human health or the environment. Indoor air quality could be impacted in the glass plant and submicro buildings due to residual soil and groundwater contamination. Groundwater contamination extends off-site to the South and Southeast but concentrations do not pose a risk to residents current use (all currently using city water from the municipal system).
Environmental/Health Threats:
Status of Investigative or Remedial Action: (10/29/92 KPD/SAS) Spill site being managed as RCRA landfill. Some contaminated soil removed. Permit for post-closure corrective action and corrective action monitoring written by DEQ. The contaminant plume has been characterized and a pump-and-treat system has been installed for use on groundwater (the system was originally installed for use on the facility's wastewater). Site Assessment recommends no further Cleanup action unless the RCRA program refers the site back to the Cleanup Program.

(9/19/00 WRM) RCRA program transfers the corrective action to the Cleanup program. DEQ, EPA, & Evanite agreed that the corrective action can be administered under a consent order attached to a Post-closure permit. (12/29/00 WRM) Consent Order and permit finalized and out for public comment from 1/16/01 - 3/3/01. (4/10/01 WRM) Consent Order signed by Evanite & DEQ.
(12/26/01 CAW) Draft focused remedial investigation work plan has been submitted and approved by DEQ. (5/6/03 CAW) Remedial Investigation(RI) and Risk Assessment reports have been submitted and are pending DEQ review.

(8/9/04 NHG) Focused RI approved by DEQ based on the following: risk assessment reviews and submittal of Focused Feasibility Study (FFS), which is to include air model and system evaluation for treatment system, pending. (9/15/04 NHG) Review of Human Health Risk Assessment initiated by DEQ. (10/15/04 NHG) DEQ reviewed and submitted comments on Ecological Risk Assessment (ERA) and Human Health Risk Assessment (HHRA). (11/4/04 NHG) DEQ PM and Toxicologist visit site for tour and meeting to discuss the ERA and HHRA. (11/23/04 NHG) DEQ received final ERA data from Evanite and approved Screening Level ERA. DEQ also recommends moving forward on the HHRA and FFS.

(8/1/05 NHG) HHRA proposed strategy scheduled for submittal to DEQ in September 2005. The HHRA is a key component for assessing the current remedy and evaluating the effectiveness of the remedy, including the post-closure permit for the cement/soil cap. (1/6/06 AMO/SRS) DEQ received the HHRA on October 28, 2005. This report is currently under review by DEQ staff.

(3/7/06 AMO/SRS) DEQ and Evanite are negotiating an addendum to the existing RI Order that will require a Focused FS to be completed.

(3/25/08 SJS/SRS) After DEQ comments to the Draft FFS and several meetings ijn the Fall of 2007, Evanite has prepared a conceptual workplan of several pilot studies including soil vapor extraction, annitional well installation, pulsed pumping, and anaerobic dechlorination that are expected to removed significant TCE mass from the site.

(1/5/09 SJS/SRS) Draft Focused Feasibility Study received by DEQ on May 31, 2007, currently under review. Second Addendum added to Consent Order, refining language related to Financial Assurance.

(3/3/10 SJS/SRS) After DEQ review of draft feasibility study Evanite embarked on several pilot studies to more effectively treat TCE from the DNAPL source zone. This included installation of several new wells in the source zone, additional off-gas treatment measures, pulsed pumping in the source zone, soil vapor extraction in the source zone, and sub-slab depressurization beneath the submicro building.

(4/30/15 SJS/SRS) Pilot studies and expansion of the well network have been very successful. In December, H&V (formerly Evanite) provided DEQ with an addendum to the FFS outlining a proposed remedy, this document was revised with DEQ comments, and DEQ has prepared a staff report outlining the remedy selection. The recommended remedial action consists of the following elements:
Hydraulic containment
Contaminant removal using soil vapor extraction and groundwater extraction, including treatment of both the water and vapor
Contaminant removal using in-situ treatment through enhanced reductive dechlorination
Engineering controls to control vapor intrusion risk in areas with shallow contamination and to prevent exposure to shallow soils
Institutional controls to prohibit residential use in areas with shallow soil contamination and to address groundwater use in areas for which controls are needed
This staff report is open for public comment in May of 2015.
