Attachment C --_ VIEAU ASSOCIATES r-�� April 30, 2015 Paul Bilotta City of Roseville 2660 Civic Center Drive Roseville, MN 55113 RE: Phase I Environmental Site Assessment Roseville Fire Station and Vacant Lots 2325 and 2335 Dale Street North & 657, 661, 667 and 675 Cope Avenue West Roseville, Minnesota 55113 Dear Mr. Bilotta: We have completed the Phase I Environmental Site Assessment for the above referenced property in Roseville, Minnesota. An invoice for the Phase I Environmental Site Assessment has been provided along with a web link to an electronic copy of the report. In summary, this assessment has revealed no evidence of recognized environmental conditions in connection with the property, except the following: A petroleum release was identified during subsurface investigation activities in 2012. Low concentrations of DRO were encountered in one soil boring, and based on the low concentrations and limited extent, the MPCA issued the release regulatory closure on January 25, 2013, indicating that no further response actions are required for this petroleum release. The identified petroleum impacts to soil qualify as a recognized environmental condition. However, based on the file closure issued for the petroleum impacts, they are viewed as a controlled recognized environmental condition. There is a potential for higher concentrations of petroleum contaminated soil in the vicinity of the removed UST which may require proper handling and disposal if encountered during redevelopment. If contaminated soil is encountered during redevelopment, it must be properly managed and may require disposal at a permitted landfill. Prior to beginning redevelopment activities, a Response Action Plan and Construction Contingency Plan should be developed for the property and submitted for review and approval by the MPCA Voluntary Brownfield Program. The following issues of environmental concern within the scope of assessment were identified in connection with the property: Pol ychlorinated biphenyls and asbestos-containin$ materials Based on limited sampling and testing completed in 2012, no polychlorinated biphenyls (PCBs) were detected in any caulking samples collected. Asbestos was detected at greater than one percent in the silver edged flashing material, and materials presumed to contain asbestos included the metal fire door and duct-reported underground transite. Note that since the fire station was in use at the time of the sampling and testing, a non-detructive survey was conducted evaluating exposed materials and not materials that may be located within walls, ceilings, other inaccessible areas, or any materials that affected operations on the property. 4570 West 77th Street, Suite 265, Edina, MN 55435 � rE� 952.893.7931 FHx 952.893J392 vieauassociates.com
