Suspect UST - War Memorial Stadium
Greensboro, North Carolina
S&ME Project No. 4358-16-027
Dear Mr. Williams:
S&ME, Inc. (S&ME) presents herein the results of our Field Investigation Services at the above-referenced
property. Our services were performed in general accordance with S&ME proposal 43-16000378 dated
May 2, 2016 that was authorized by the City of Greensboro.
Project Information
Based upon information obtained during an April 22, 2016, meeting between Richard Lovett with the City
of Greensboro and our Ed Henriques, we understand that a probable Underground Storage Tank (UST)
was identified at the site based on a Geophysical Assessment performed by SITECH dated January 10,
2016. The probable UST was identified within the existing parking lot located along Yanceyville Street in
front of the War Memorial Stadium. A copy of the SITECH report is contained in Attachment I. The City
of Greensboro directed S&ME to assume a UST was present, to conduct permanent closure of the UST,
and if evidence of a release was observed, and conduct initial abatement actions.
Field Activities
Prior to conducting site activities, S&ME personnel prepared a health and safety plan (HASP) to comply
with 29 CFR 1910.120, hazardous waste operations and emergency response (HAZWOPER) rule for the
protection of workers at uncontrolled hazardous sites. S&ME called for underground utility mark-outs
(811). On May 31, 2016, S&ME met Superior Locate on-site to locate private utilities in the area of the
proposed excavation. S&ME contacted Ms. Sharon Cihak with Guilford County Public Health,
Environmental Health by phone to report the proposed UST removal date.
On June 1, 2016, S&ME and A&D Environmental Services, Inc. (A&D) mobilized to the site to complete the
proposed UST exploration and removal activities. The location of the geophysical anomaly was located in
the parking lot using information obtained from the SITECH report. In the area of the geophysical
anomaly the concrete pavement system was cut and a section of the pavement system was removed to
expose the underlying soil. Using a mini-excavator A&D completed exploratory excavations in the area
associated with the geophysical anomaly. What appeared to be a piece of expanded metal was

discovered buried in the soil (see photograph in Attachment II). Exploratory digging in the targeted area
was extended to a depth of approximately 5 feet below grade. The exploration activities revealed no
visible indications of a UST and S&ME did not detect petroleum odors in the soil. Given the absence of an
observed UST and no observed petroleum odors in the soil, soil samples were not collected for laboratory
analyses. Further exploration for a potential UST in the area of the geophysical anomaly was not
warranted. S&ME contacted Ms. Cihak by phone and informed her of the investigations and that they
revealed no evidence of a UST.
The excavation was backfilled with stone up to and flush with the top of the adjacent pavement. The area
where the concrete was removed for this exploration will be paved at a date not yet determined.
Conclusions
On May 31, 2016, exploratory excavations were completed in the area of SITECH reported geophysical
anomaly, inferred to be a UST. No UST was observed. The exploration activities discovered a piece of
expanded metal buried beneath the pavement system at the location of the geophysical anomaly. In view
of these findings, S&ME has inferred that the geophysical anomaly was likely a response due to the buried
metal rather than a buried UST.
Closure
S&ME appreciates the opportunity to be of service to the City of Greensboro. If you have any questions
regarding our completed services, or if we may be of any further assistance, please call.
Sincerely,
S&ME, Inc.
