Dear Mr. Chaves:
RE: Petroleum Tank Release Site Closure
Site: CFI Trucking, 15597 North 59th Street, Oak Park Heights
Site ID#: LEAK00003966
The Minnesota Pollution Control Agency (MPCA) staff has determined that the
cleanup performed in response to the petroleum tank release at the site
referenced above has adequately addressed the petroleum contamination, and
therefore the file regarding this release will be closed.
On April 26, 1991, a petroleum tank release was reported to the MPCA. Since
then, the following corrective actions have been taken in response to the
release:
- One 10,000 gallon underground storage tank previously containing fuel oil
was removed.
- Approximately 10 cubic yards of petroleum contaminated soils were excavated
and thermal treated at Clean Soils Incorporated.
- Soil excavation extended down 6 to 8 feet below grade. Soil vapor headspace
` analysis for hydrocarbons utilizing a photoionization detector indicated low
levels ranging from 1 to 3 parts per million (ppm) at 8 to 8.5 feet.
Chemical analyses of two soil samples taken from each end of the excavation
basin detected 0.42 to less than 0.06 ppm total hydrocarbons as fuel oil.
Analysis for benzene, ethyl benzene, toluene, xylene compounds indicated
levels of less than 0.002 ppm. The water table is at 8 feet and appears to
not be affected by the release. Excavation was limited to the north end by
an existing building. Based on available data, the low levels of petroleum
contaminated soil that remain in these isolated areas of the site do not
pose a threat to public health or the environment.

more investigation or, cleanup work in response to this release. However, the
MPCA reserves the right to reopen this file and require additional work if in
the futuremore*work is determined to be necessary, and this letter does not
release any,party. from liability for this contamination.
Because you performed the requested work, the state may reimburse you for a
major portion of your costs. The Petroleum Tank Release Cleanup Act
establishes a fund which in certain circumstances provides partial
reimbursement for petroleum tank release cleanup costs. This fund is
administered by the Petroleum Tank Release Compensation Board (Petro Board).
More specific eligibility rules are available from the Petro Board

Please provide the following items when they are available: Please forward a
copy of the signed thermal application to Clean Soils Incorporated as well as
the subsequent post burn analyses.
Thank you for your cooperation with the MPCA in responding to this petroleum
tank release to protect the public health and the environment of the state of
Minnesota. If you have any questions regarding this correspondence, please
