Proposed Remedy for PECO, Inc.

COMMENTS DUE: July 30, 2012 5:00 PM

PROJECT LOCATION: 4707 SE 17th Avenue, Portland, OR

PROPOSAL: In accordance with ORS 465.200, the Department of Environmental Quality (DEQ) invites public comment on its proposed remedy for the site.

HIGHLIGHTS: The PECO facility occupies approximately 6 acres and includes four industrial-use buildings and associated parking areas located near SE Schiller Street between 16th and 18th Avenues in Portland, Oregon. The facility is used for the manufacture of parts for the aerospace industry, and includes die casting, machining, and plastic injection molding. Surrounding use is primarily commercial or industrial.

Environmental investigation has identified solvents including tetrachloroethene and trichloroethene in soil and groundwater. Treatment has reduced contaminant levels, but concentrations continue to exceed DEQ screening values in some areas. Polychlorinated biphenyl (PCB) contamination in soil and building materials was previously removed to DEQ and EPA satisfaction, and does not require further action.

A remedy is proposed to address remaining soil and groundwater that poses a potential risk to site users. The action includes removal of soil below the West Plant exceeding “hot spot” values, treatment of shallow groundwater below the East Plant, and ongoing operation of a soil vapor collection system in both buildings to capture contaminated vapor that could enter occupied buildings. If properly implemented, the remedy will reduce contamination to levels that do not pose a risk.

DEQ welcomes the public’s comments on the proposed remedial actions.

HOW TO COMMENT: To review project records, contact Dawn Weinburger at (503) 229-5425 and ask for records for Environmental Cleanup Site Information (ECSI) site #178. The DEQ Project Manager is Daniel Hafley (503-229-5417). Written comments should be sent to Daniel Hafley at the Department of Environmental Quality, Northwest Region, 2020 SW 4th Avenue, Suite 400, Portland, OR 97201 and must be received no later than 5 pm on July 30, 2012. A public meeting will be held to receive verbal comments if requested by 10 or more people, or by a group with a membership of 10 or more. Site information can also be found in DEQ’s on-line ECSI database at: http://www.deq.state.or.us/lq/ECSI/ecsi.htm, by searching on Site ID #1973.

THE NEXT STEP: DEQ will consider all comments received and make a final decision on the proposed site remedy after consideration of these comments.

Proposed Approval of Cleanup at PacifiCorp Youngs Bay Site

COMMENTS DUE: 5 p.m., Tuesday, July 31, 2012

PROJECT LOCATION: 1224 West Marine Drive Astoria, OR

PROPOSAL: The Department of Environmental Quality invites public comment on the proposed conditional approval of environmental cleanup action at the PacifiCorp Youngs Bay site. This is also known as a conditional no further action determination.

HIGHLIGHTS: The PacifiCorp Youngs Bay site consists of an upland area that is approximately 4.5 to 5 acres in size, a shoreline slope that separates the upland from the intertidal area, and an off-shore zone of intertidal mudflats that extends southward several hundred feet into Youngs Bay. Between 1921 and 1950, PacifiCorp manufactured compressed, petroleum-based gas for heating and lighting at the site. Petroleum oils were used as a base stock for gas manufacturing. Between 1922 and 1954 electricity and steam were also produced at the site from a generating plant that used wood-based hog fuel. Tarry residues were released from the site during gas manufacturing operations, leaving tarry material along the shoreline of the property and a tar “body” that extends from the shore approximately 300 feet into Youngs Bay. Contaminants associated with oil and tar were also detected at elevated concentrations in upland site soils.

In 1987, under Remedial Action Agreement between PacifiCorp and DEQ, PacifiCorp demolished the existing site structures and placed demolition material in the southeastern portion of the upland. This area was then covered with sand to fill voids and approximately 2 feet of clean soil. The soil was vegetated and the entire site was fenced.

In September 2004, PacifiCorp excavated lampblack-contaminated soil near the site entrance and disposed of the material in a permitted landfill.

In the summer of 2005, PacifiCorp removed a portion of the off-shore tar and capped the remaining tar as described in the DEQ record of decision issued February 2005.

In 2011, PacifiCorp excavated the most contaminated soils in the upland portion of the site and placed them in an extension of the existing capped area onsite or, if product was observed, disposed the material at a permitted landfill, as described in the DEQ record of decision issued September 2010.

PacifiCorp prepared Long-Term Monitoring and Maintenance Plans for the upland and shoreline/off-shore portions of the site. In addition to regular monitoring and maintenance of the caps, inspections will be conducted after any events that could impact cap integrity.

Based on evaluation of the actions described above, DEQ is proposing that no further action be required at the PacifiCorp Youngs Bay site. The proposed cleanup approval is conditional because of the need to maintain engineering controls and conduct long-term monitoring and maintenance of cleanup measures at the site.

HOW TO COMMENT: A memorandum describing the basis for the no further action is available at: http://www.deq.state.or.us/Webdocs/Forms/Output/FPController.ashx?SourceId=147&SourceIdType=11. Complete site files are available for public review at DEQ’s Northwest Region Office in Portland. To schedule an appointment to review files, call 503- 229-6729. Send written comments to Project Manager Jennifer Sutter, DEQ Northwest Region, 2020 SW 4th Ave., Portland, OR 97201 or sutter.jennifer@deq.state.or.us, by Tuesday, July 31. Contact Sutter at 503- 229-6148.

THE NEXT STEP: DEQ will consider all public comments and the DEQ Northwest Region Administrator will make and publish the final decision after consideration of these comments.

REQUEST FOR COMMENTS
PROPOSED NO FURTHER ACTION DETERMINATION,
FORMER CIRCLE 9 DRYCLEANERS CORVALLIS, OREGON

COMMENTS DUE: July 30, 2012

PROJECT LOCATION: The former Circle 9 Drycleaners is located in the Circle 9 Plaza at 960 NW Circle Boulevard in Corvallis Oregon. The site consists of tax lots 00300, 00304, 00306, and 00307 as described on Map No. 110526AC, Township 11 South, Range 5 West, Section 26 (the “Property”).

PROPOSAL: DEQ is proposing that no further action is required at the site to human health and the environment.

HIGHLIGHTS: A drycleaner operated on the Property from around 1978 to around 1990. During historic dry cleaner operations at the Property, hazardous substances were released at and from the Property. Between 2002 and 2007, Multiple rounds of soil and groundwater investigation were conducted under DEQ supervision. During the investigation, soil and groundwater contamination were found on the site. A soil cleanup occurred in 2008, followed by mitigation measures to prevent chlorinated solvent vapors (from dry-cleaning chemicals) from entering the buildings on site. In 2009, DEQ discovered multiple nearby wells were contaminated with chlorinated solvents at levels that are not safe to drink. DEQ believes these chemicals originated at the former Circle 9 Drycleaners facility. Other currently unknown sources in the area may also have contributed to contamination in the Lawndale wells. DEQ provided bottled water to affected residents and then hooked up residents to carbon filtration units to ensure safe household water supplies. DEQ will maintain these treatment systems until concentrations of chlorinated solvents in the groundwater decrease to safe levels. Since the soil contamination at the site was removed, there are no additional actions that could be taken that would improve groundwater conditions in the nearby area. Since conditions on site and off site are protective of human health and since there is no ecological risk posed by the groundwater contamination, DEQ has determined that no further action is required. On July 1, running through July 30, 2012, DEQ will provide public notice and opportunity to comment on the determination.

HOW TO COMMENT: The proposed determination is available at DEQ’s Western Region Office, at 165 E 7th, Suite 100, Eugene, Oregon 97401, or electronically by request to brown.geoff@deq.state.or.us. To review files at DEQ’s office, please contact DEQ’s file review coordinator at (541) 686-7819 to make an appointment. Comments may be submitted to Geoff Brown, DEQ Cleanup Project Manager, by email at brown.geoff@deq.state.or.us ; by mail at DEQ, 167 E 7th, Suite 100, Eugene, Oregon 97401; or by fax at 541-686-7551.

THE NEXT STEP: DEQ will review and consider all comments received during the comment period. Once all comments have been considered and addressed, DEQ will issue a letter of no further action to the property owner and change the status of the site in the ECSI database.

Proposed Cleanup Approach for Canoe Bay Shoreline

COMMENTS DUE: 5 p.m., Tuesday, July 31, 2012

PROJECT LOCATION: Canoe Bay, North side of Hayden Island, Portland

PROPOSAL: The Department of Environmental Quality invites public comment on the proposed cleanup approach for contaminated shoreline and bank areas on the west side of Canoe Bay, an inlet off the Columbia River located on the north side of Hayden Island. DEQ proposes that contamination present along the western shoreline of the bay adjacent to property owned by Inland Sea Maritime Group be capped as part of a larger shoreline stabilization project in this area. Contamination in this area appears to be the most significant remaining source of contamination to Canoe Bay. Once these shoreline sources of contamination are cleaned up, contaminant concentrations in bay sediments are expected to decline over time through natural recovery processes.

HIGHLIGHTS: Canoe Bay is a 7.6-acre rectangular inlet off the Columbia River located on the central north side of Hayden Island. Inland Sea Maritime Group owns approximately 6 acres of upland land on the southwestern edge of the bay. Schooner Creek Boat Works operates a boat maintenance facility on a portion of the upland property.

Historic dumping occurred into and around Canoe Bay between 1966 and 1989, creating a debris pile on the eastern shoreline of Canoe Bay. Sampling of Canoe Bay sediments and shoreline soils indicates the presence of contaminants including polychlorinated biphenyls (known as PCBs), metals, polycyclic aromatic hydrocarbons, and tri-butyl tin. The highest levels of contamination were found in the vicinity of the debris pile. Elevated levels of metals and tri-butyl tin were also found in the vicinity of the Schooner Creek stormwater outfall.

DEQ is proposing that the owner cap the more highly contaminated soils and sediments in the vicinity of the debris pile and stormwater outfall in conjunction with a shoreline stabilization project. The proposed clean-up would include placing an Envirolok® system on the steeper portions of the shoreline and a clean sand cap from the foot of the slope out approximately 12 feet into the bay. Envirolok® consists of non-biodegradable polypropylene bags filled with soil and tied together to create a stable cap that will support vegetation. Containerized plants would be placed in conjunction with the Envirolok® system and would act to lock the bags to each other and the surrounding soil. The sand cap would cover a zone of contaminated sediment adjacent to the shoreline. The shoreline cap will cut off exposure to contaminants and prevent further erosion of contaminated material into Canoe Bay. Once this source is controlled, DEQ expects that over time, clean sediments will cover existing contamination in the bay, reducing concentrations to protective levels.

The proposed remedy is considered to be consistent with Oregon rule and statute and, if properly implemented, protective of public health and the environment.

HOW TO COMMENT: A DEQ staff report outlining the proposed cleanup approach is available for public review at DEQ’s Northwest Region Office in Portland and on line at http://www.deq.state.or.us/Webdocs/Forms/Output/FPController.ashx?SourceId=3333&SourceIdType=11. To schedule an appointment to review files in DEQ’s Northwest Region office, call 503-229-6729. Send comment to DEQ Project Manager, Jennifer Sutter, DEQ Northwest Region, 2020 SW 4th Ave., Portland, OR 97201 or sutter.jennifer@deq.state.or.us by Tuesday, July 31, 2012. For more information contact Jennifer at 503-229-6148.

THE NEXT STEP: DEQ will consider all public comments and the Regional Administrator will make and publish the final decision after consideration of these comments.

Proposed No Further Action for RK Wilson Property

COMMENTS DUE: 5 p.m., Monday, July 30, 2012

PROJECT LOCATION: RK Wilson Property at 7360 Pointer Road and 7385 SW Canyon Lane Beaverton, OR

PROPOSAL: The Department of Environmental Quality invites public comment on DEQ’s proposal to issue a No Further Action determination for the site, following completion of remedial actions at the RK Wilson Property.

HIGHLIGHTS: The site is located in the West Slope neighborhood in Beaverton, Oregon, between Highway 26 to the north and Canyon Lane. Historical site use included rural residential and agricultural land uses, and greenhouse operations on a portion of the site from the 1930s until 2005. Mr. Ronnie Wilson purchased the site in 2005 and demolished the greenhouses.

The Tualatin Parks and Recreation District plans to purchase the site for future development as a neighborhood park.

Site investigations in 2011 to 2012 resulted in the excavation and disposal of 435 tons of soils that exceeded residential risk based concentrations for arsenic. All remaining surface soils are below pesticide and metals relevant risk criteria for residential exposures.

Ground water sampled from an onsite well did not exceed risk standards but exceeded DEQ’s arsenic drinking water standard. However it was below federal standards. Shallow ground water from an onsite irrigation well is not currently used and future groundwater use is unlikely due to city water availability.

Based on the review of site information, DEQ proposes that no further action is required to address environmental contamination at the site.

HOW TO COMMENT: To review project records, contact Dawn Weinberger at 503 229-6729. Send written comments by 5 p.m., July 30, to Project Manager, Jim Orr at the Department of Environmental Quality, Northwest Region, 2020 SW 4th Avenue, Suite 400, Portland, OR 97201, orr.jim@deq.state.or.us. DEQ will hold a public meeting to receive verbal comments if review is requested by 10 or more people or by a group with a membership of 10 or more. The DEQ staff report for this site is at: http://www.deq.state.or.us/Webdocs/Forms/Output/FPController.ashx?SourceId=5281&SourceIdType=11

THE NEXT STEP: DEQ will consider all comments received and make a final decision after consideration of these comments.

ACCESSIBILITY INFORMATION: DEQ is committed to accommodating people with disabilities. Please notify DEQ of any special physical or language accommodations or if you need information in large print, Braille or another format.
