Excavation Report for PetroLeum ReLease Sites
6/23/92; AE #1125; MPCA Leak #4254
C. If the release was associated with the lines or
dispensers, briefly describe the problem:
Because of the petroleum contamination discovered in
the gasoline tank basin and good condition of the removed
gasoline tank, the lines or dispenser may have been a
contributing factor in the petroleum release.
D. If the release was a surface spill, briefly describe the
problem:
Occasional overfills may have been an additional source
of the release.
IV. EXCAVATION
Summary:
Westside Equipment was contracted by Scott Rice Telephone
Company to remove the underground storage tanks at this location.
Applied Engineering was hired by Scott Rice Telephone to document
the tank removal and to perform environmental related services
On July 17th, the 800 gal fuel oil tank was removed. During
the tank removal, a release was discovered in the tank basin.
Soil with any detectable petroleum levels was removed from the
fuel oil/used oil tank basin and stockpiled.
The following day, the 4,000 gallon gasoline tank was
removed. A release was also discovered in this tank basin. Soil
with HNU levels greater than 10 ppm was removed from the gasoline
tank basin and stockpiled. Soil with HNU levels below 10 ppm was
left in place or separated and later used as backfill.
The removal of contaminated soil in the gasoline tank basin
of was inhibited by the sewer and drain tile lines. A soil
sample was taken from the Northwestern corner of the excavated
gasoline tank basin to represent the worst contamination
remaining in place.
As part of the site investigation, a water sample was taken
from the drain tile outlet.
A. Dimensions of excavation (2 separate excavations):
Approx.
30' x 20' x 10' deep
18' x 7' x 9' deep

B. Original tank backfill material (sand, gravel, etc.):
Sand
C. Native Soil Type (clay, sand, etc.):
Clay
D. Quantity of contaminated soil removed (cubic yards):
118 CY (approx. 70 gasoline / 48 fuel oil)
E. Was ground water encountered or was there evidence of a
seasonally high ground water table? Yes At what depth?
Water seeped into the excavation at approximately 6 feet
deep.
F. If a soil boring was necessary (as indicated in part VI
of "Excavation of Petroleum Contaminated Soil" for sand and silty
sand native soils) describe the soil analytical and soil vapor
headspace results. Attach the boring logs and laboratory results
to this report.
N/A
G. If ground water was encountered or if a soil boring was
conducted, was there evidence of ground water contamination?
Specify, e.g., free product (specify thickness), product sheen,
ground water in contact with petroleum contaminated soil, water
analytical results, etc.
Water was encountered at approximately 6 feet deep. No
free product or visual evidence of contamination was
observed.
H. Was bedrock encountered in the excavation? No
At what depth?

I. Were there other unique conditions associated with this
site? If so, explain.
Sewer and drain tile lines were located approximately
12 feet and 7 feet West of the removed 4,000 gallon gasoline
tank. (See attached Drawing 1125C.)
V. SAMPLING
A. Briefly describe the field methods (including use of a
photo ionization detector) used to distinguish contaminated from
uncontaminated soil:
Field methods included visual and olfactory senses as
well as use of an HNU Photoionization Detector with a 10.2
eV lamp source in accordance with the MPCA Jar Headspace
Analytical Screening Procedure.
B. List soil vapor headspace analysis results. Indicate
sampling locations using sample codes (with sampling depths in
parentheses), e.g. SV-1 (2'), SV-2 (10'), etc. Samples that were
taken at different depths at the same location should be labeled
SV-IA (2'), SV-IB (4'), SV-1C (6'), etc. These should correspond
with the codes on the site map in part VI.

C. Briefly describe the soil sampling and handling
procedures used:
Soil sampling followed MPCA recommended procedures
including cold storage until delivered to the laboratory.
All analyses were performed using EPA or other accepted
methodologies.
Two samples were taken from beneath both the removed
4,000 gallon gasoline and the 800 gallon fuel oil tanks.
One sample was taken from beneath the removed gasoline pump.
One sample was taken from the Northwestern corner of the
excavation sidewall of the gasoline tank where the sewer and
drain tile lines inhibited excavation. One sample was taken
along the Western perimeter of the removed fuel oil tank
basin next to the building where contaminated soil remained
in place. One stockpile sample was taken and one sample was
taken of the ground water near the drain tile outlet.
Page 9
Excavation Report for Petroleum Release Sites
6/23/92; AE #1125; MPCA Leak #4254
All samples were analyzed for Total Petroleum
Hydrocarbons as both gasoline and fuel oil, BTEX, MTBE, and
Lead. The water sample and the soil sample taken from the
fuel oil/used oil tank basin were also analyzed for volatile
organic hydrocarbons, method MHD 465C.
D. List the appropriate soil sample analytical results
below (refer to the MPCA document "Soil and Ground Water Analysis
at Petroleum Release Sites"). If the petroleum was not gasoline
or fuel oil attach a separate table. Code the samples (with
sampling depths in parentheses) SS-l (8'), SS-2 (4'), etc. These
should correspond with the codes on the site map in part VI.

VII. SUMMARY
Briefly summarize evidence indicating whether or not additional
investigation is necessary at the site, as discussed in part VI
of the MPCA document "Excavation of Petroleum Contaminated Soil".
Discussion
Soil Contamination:
During excavation, the darker, obviously contaminated soil
was removed until soil was reached with natural color and odor.
Cleanup of the soil was also confirmed by favorable HNU levels.
The four tank bottom soil samples, SS-I, SS-2, SS-4, and SS-5
taken at 9 feet and 10 feet deep respectively, indicated non-
detectable hydrocarbon concentrations.
There was however, the area on the northwestern
the sewer and drain tile lines inhibited excavation.
laboratory analyses indicated a TPH concentration of
gasoline there.

Groundwater Contamination:
Although water was encountered in the excavation, there was
no evidence of contamination.

,
Excavation Report for Petroleum Release Sites
6/23/92; AE #1125; MPCA Leak #4254
Identification of Potential On and Off site receptors (i.e. water
wells, surface water, basements, etc.):
Since there was no evidence of groundwater contamination, an
MPCA Ground Water Receptor Survey was not performed. However,
the immediate area is on a municipal water supply and there are
no apparent threatened receptors.
Conclusions:
Based on the results identified in this report, the
excavation of the tank basins was successful in removing all
petroleum impacted soil in accordance with MPCA guidelines.
Based on the laboratory water sample results from near the
drain tile outlet, there appears to be no significant impact on
the groundwater.
Recommendations
No further action is recommended.
