Pudil SEP 2 9 Z005 President and CEO CITY OF or, Washington Scientific Industries, Inc. NO 213 Chelsea Road Monticello, MN 55362 RE: Washington Scientific Site II, 2605 West Wayzata Boulevard, Orono MPCA Project Number VP 10021 No Action Determination Dear Mr. Pudil: The Minnesota Pollution Control Agency(MPCA) staff in the Voluntary Investigation and Cleanup (VIC)Unit has been requested to provide a No Action Determination for releases identified at the Washington Scientific II site located at the above referenced address (the Site). The Site is approximately 25 acres in size and the property and facility was owned and operated historically by Washington Scientific Industries (WSI), who operated a machining, assembling and manufacturing facility for precision metal components. The Site property is currently owned by WJM Properties, LLC, and is used as a car storage facility. WSI identified chlorinated solvents in the soil and ground water at the Site in 1987 during parking lot construction activities. Subsequent ground water monitoring activities identified a release of volatile organic compounds (VOCs) in the shallow glacial ground water and associated soils in the southern portion of the Site. The identified release for the purposes of this letter consists of the VOCs identified in the ground water including trichloroethylene; 1,1-dichloroethane; 1,1-dichloroethylene; cis-1,2- dichloroethylene; 1,2-dichloroethylene; tetrachloroethylene; vinyl chloride; bromomethane; and methylene chloride (the Identified Release). A Limited No Action Determination for contaminated soils associated with this VOC release at the Site was issued by the MPCA on August 27, 2002. In 1988, WSI installed a ground water pump-out system as a remedy and to provide ground water containment under the oversight of the MPCA Resource Conservation and Recovery Act (RCRA) Corrective Action Program. After several years of ground water monitoring activities, in August 1998, regulatory oversight for the Site was transferred to the MPCA VIC Program. Additional soil and ground water investigations including an updated ground water receptor survey was conducted by i WSI. The receptor survey identified several domestic wells located within the glacial deposits approximately 1000 feet south and downgradient of the Site. The MPCA VIC staff approved a remedial system shutdown and closure plan in 1999. This plan involved the installation and monitoring of sentinel wells along the southern Site property boundary screened approximately in the same aquifer as the domestic wells south of the Site. The sentinel wells confirmed the presence of a thick glacial clay dominant sequence in the subsurface separating glacial sands. Since shutdown of the remediation system in 1999, the ground water has been monitored in accordance with the shutdown 520 Lafayette Rd.

Mr. Michael J. Pudil Page 2 September 21, 2005 plan in order to verify the stability and localized extent of the ground water contamination. Since the remediation system has been shutdown and dismantled, the extent of the ground water plume has remained stable with no evidence of further migration. Based on a review of the information provided to the MPGA, a determination is hereby made to take no action with regard to the Identified Release to ground water; specifically, the MPCA staff will not refer the Identified Release to ground water to the U.S. Environmental Protection Agency for inclusion on the Comprehensive Environmental Response, Compensation and Liability Information System list, to the State Site Assessment staff for evaluation, or to the MPCA Commissioner for the placement of the Site on the Permanent List of Priorities. Please be advised that the determination made in this letter is subject to the disclaimers found in Attachment A. If you have any questions about the contents of this letter, please contact Patrice Jensen at (651) 296-7744 or Richard Jolley at (651)297-5573.
