Dear Ijaz Haidar:
The Minnesota Pollution Control Agency (MPCA) staff in the Voluntary Investigation and Cleanup (VIC)
Program has been requested to provide a No Action Determination for releases identified at the SJ
Computers site, located at the address referenced above (the Site).
The MPCA staff has reviewed the information submitted for the Site. The 6.23 -acre Site consists of a
single parcel that has been developed since 1986 when the current Site building was constructed. The
Site has been used as an office and warehouse (storage and cutting/sewing of medical braces and other
soft goods) since 1986, with no known use or storage of chlorinated solvents. The Site was previously
enrolled in the MPCA VIC Program as the 1200 Trapp Road site (VP3570). SJ Computers LLC intends to
use the Site for a commercial sales and computer repair facility.
Limited environmental investigations were completed at the Site in February 1993 and August 1993.
Two soil samples were collected from an area adjacent to the former chemical storage rooms and
analyzed for volatile organic compounds (VOCs) and Resource Conservation and Recovery Act (RCRA)
metals. Chlorinated VOCs were not detected in the soil samples. Metals were detected within the range
of typical background concentrations.
Three groundwater samples were collected at the Site from temporary monitoring wells in February
1993 and analyzed for VOCs. Trichloroethene (TCE) was detected in groundwater at a concentration less
than the current Health Risk Limit (HRL) established by the Minnesota Department of Health (MDH).
Three groundwater samples were collected at the Site from permanent monitoring wells in August,
September, and October 1993 and analyzed for VOCs. Trichloroethene was detected in groundwater in
one monitoring well on the southwest corner of the Site at concentrations greater than the current HRL
established by the MDH.

Fourteen sub -slab soil vapor samples were collected at the Site in September 2024 (non -heating season)
and November (heating season) and analyzed for VOCs. Tetrachloroethene (PCE) and 1,1,2 -
trichloroethane (1,1,2 -TCA) were detected in soil vapor at concentrations less than or slightly greater
than their industrial intrusion screening values (ISV).
For the purpose of this letter, the identified release at the Site is defined as PCE and 1,1,2 -TCA in soil
vapor (Identified Release). This letter does not address petroleum -related compounds. Technical
assistance for petroleum -related compounds may be obtained through the MPCA's Petroleum
Brownfield Program.
Given the current commercial/industrial land use, the soil vapor assessment completed at the Site did
not identify an area of concern, either for the Site or neighboring properties. Based on the two seasonal
soil vapor sampling events, the MPCA concurs that the existing commercial/industrial building at the Site
does not require a vapor mitigation system.
Based on a review of the information provided to the MPCA, a determination is hereby made to take no
action with regard to the Identified Release; specifically, the MPCA staff will not refer the Identified
Release to the U.S. Environmental Protection Agency for inclusion in the Superfund Enterprise
Management System (SEMS) database, 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.
This determination is subject to the following conditions and qualifications:
This determination is based solely on the results of the soil vapor investigation conducted on the
Site. Due to the lack of current information regarding other media, this letter does not address
any conclusions or representations regarding the future need for further investigation or
response actions relating to soil or groundwater.
2. This determination is contingent upon the continued commercial/industrial use of the Site.
Changes in land use can create new potential exposure pathways for soil or soil vapor
contaminants and should be preceded by a concurrent evaluation of Site conditions.
3. The soil vapor determination conveyed in this letter applies only to the existing building at the
Site, as described in the Phase 11 Environmental Investigation, dated November 2024, and
prepared by Landmark Environmental. Future construction activities at the Site (e.g., potential
addition, new building, new utility trenches, etc.) should be preceded by a soil vapor
investigation within the footprint of the proposed construction area, so a vapor mitigation
decision for the new feature can be made based on concurrent data.
Please be advised that the determination made in this letter is subject to the disclaimers found in
Attachment A.
