St. Paul, Minn. — The Minnesota Pollution Control Agency (MPCA) is proposing to delete one from, and add 10 contaminated sites to, the state’s Superfund Permanent List of Priorities. These sites have known risks to human health and the environment, or the potential to pose these risks. The public is invited to comment on the proposed sites’ additions and deletion by June 10, 2016.
MPCA Remediation Division staff will make a presentation about the proposed list changes to the MPCA Advisory Committee on May 24 in St. Paul. This meeting will be open to the public; however, formal comments about the proposal must be made to the designated staff contact described below.
Nine of the 10 sites are located in the Twin Cities metro area and the remaining site is in Cloquet, Minn.
Sites being added to the list are current or former dry cleaners, metal platers or other industries that use industrial chemical solvents, including trichloroethylene (TCE), and perchloroethylene (PCE, or perc) in their business processes. When these chemicals are spilled or otherwise migrate into soil or groundwater beneath the establishment, the resulting contamination can spread outward through groundwater or upward as vapors into residential or commercial basements and foundations.
The Metro-area sites being proposed for addition are:
- 55th Street and Lyndale Avenue South, Minneapolis, is the site of a former dry cleaning operation; the MPCA is investigating a PCE release which has contaminated groundwater and soil vapor;
- Arcade and Hawthorne, St Paul, is the site of a former dry cleaner and auto service station where industrial solvents have been found in groundwater and soil;
- Hospital Linen, St Paul, is a former commercial laundry and industrial dry cleaning site where PCE was found in soil and soil vapor;
- Lyndale Avenue Corridor, Bloomington, is home to more than 40 commercial and industrial businesses, including vehicle repair, dry cleaning and manufacturing, that have or currently use hazardous chemicals which contaminated soil and groundwater;
- Pure Oil Bulk Storage Facility, Excelsior, where industrial solvents PCE and TCE were detected in groundwater and soil vapors, from an unknown source;
- Southeast Hennepin Area Ground Water and Vapor Plume, Hennepin County, is a TCE-contaminated site that has ongoing groundwater monitoring and soil vapor testing;
- Universal Plating Facility, Minneapolis, was a chemical and mechanical plating facility that closed in 2009 and has been included in the MPCA’s Voluntary Investigation and Cleanup program since 2014;
- University Avenue and Pascal Street, St Paul, is an area that has had TCE and PCE detected in soil and groundwater; and,
- West 66th Street and Vincent Avenue, Richfield, was the site of small spills or disposal of the dry cleaning chemical PCE that contaminated groundwater.
The Cloquet-based site being proposed for addition is the former D’s Fabric Care, which was a dry cleaning operation that is being investigated for groundwater and soil vapor contamination.
The one site proposed for delisting is Boyer Lumber Superfund site in Virginia, Minn. This site was an undeveloped mining property that later became a manufacturing facility and later a lumber yard and hardware store. Based on MPCA hazardous materials cleanup actions, no further work is necessary at this site to protect public health and the environment.
Links to more information on all these sites is on the MPCA's Superfund Program webpage.
Placement on the PLP list makes funding available to investigate and clean up these sites. The last time the agency added or deleted a site from this list was in September 2015.
Comments about the proposed site additions and deletion must be made by 4:30 p.m. on June 10, 2016, to Tom Higgins, MPCA Site Remediation and Redevelopment Section, at 651-757-2436, 800-657-3864 or email@example.com.
