Re: Fuel Oil UST removal
Dooley Residence
44 East Terrace, South Burlington, Vermont
Dear Ms. Dooley:
On 3 September 2013, Environmental Compliance Services (ECS) completed a Closure Assessment for
one 275-gallon #2 fuel oil underground storage tank (UST) at the above-referenced site. Enclosed are
UST closure assessment reports, a site sketch with PID readings and photographs. A copy of this report
will be submitted to the Vermont Department of Environmental Conservation (VT DEC) on your behalf.
Findings: One 275-gallon fuel oil UST was removed. The tank was in poor condition with
several small holes and rust. The UST is greater than 25 years old and has been
out of use since the installation of natural gas at the site. Photoionization
detector (PID) soil headspace readings were detected at values ranging from 0.0
to 916 parts per million (ppm), above the VT DEC soil threshold value for fuel
oil of 10 ppm. Olfactory evidence of fuel oil contamination was noted.
ECS field personnel and Enpro Services Inc., used the onsite mini-excavator in
an attempt to define the limits of the contamination. Due to space limitations and
the proximity of the UST to the foundation of the house, the limits of
contamination were not defined. The excavation stopped at approximately 6 feet
below the ground surface (bgs) where the footer of the foundation wall was
encountered. Groundwater was not encountered in the excavation however; due
to the groundwater intrusion near the bottom of the foundation wall in the
basement, ECS believes that the depth to groundwater may be as high as 7 feet
bgs during seasonal water table fluctuations. The soil consisted of very dry fine
sand with trace silt. All soils were backfilled into the excavation.
The basement of the residence was inspected and screened with a PID along the
west wall were the UST was located. The copper feed line had previously been
cut and capped in place. The PID readings in the gap of the foundation where the
feed line came in was 0.2 ppm. The ambient air in the basement was 0.7 ppm.
No petroleum related odors were observed in the basement by ECS during the
screening or historically by the homeowner.
Recommendations: ECS recommends an Initial Site Investigation at the site to determine the extent
of contamination and if groundwater has been impacted. Based on the Vermont
Department of Environmental Conservation (VT DEC) “Investigation and
Remediation of Contaminated Properties Procedure” updated April 2012, an
additional vapor intrusion evaluation will be necessary due to PID readings
>10ppm within 5 feet of the house.
ECS has appreciated the opportunity to assist you with this work. Please contact me at (802) 241-4131 if
you have any questions or need additional information.
Sincerely,
ENVIRONMENTAL COMPLIANCE SERVICES, INC.
