Dear Mrs. Dietrich:
Geological Resources, Inc. (GRI) presents this letter as a summary of the Geophysical Survey conducted
at the above-referenced site. On February 11, 2014 GRI supervised a ground penetrating radar (GPR)
survey of the site. \\!"here warranted, electromagnetic (EM) imaging was also utilized. The survey was
conducted to reduce uncenamties about the property prior to acquisition. Additionally, GRI inspected the
entirety of each building. The findings are summarized below by building. A Geophysical Results Map
is attached as Figure I. Photographs taken during the survey showing areas of interest are also attached.
2307 North Main Street (fonner main shO\\TOOm building) -GPR and EM were conducted inside the
main service bay to locate any hydraulic USTs and associated piping. GPR was conducted around the
perimeter of the building and across the lot, with special attention to the west side of the property where
reported USTs may suJJ remain or were removed, and special attention to any patched areas in the paved
lot to identify any drains.
1) Three areas interpreted to be backfilled excavauons were noted as follo\\ s two adjacent to the
south wall (Features 1 and 2 on Figure l , Photo A). and one to the southwest of the southwest
corner of the building (Feature 3, Photo B. Photo C, Photo D). Reportedly, these are the locauons
of former USTs; however. no USTs were identified in the excavations. No piping was noted in
any basin; however, a pipe originaung inside the building and exiting through the wall was
observed on the south side of the building (adjacent to the eastern-most excavated area) (Feature
4. Photo E).
2) A disturbed area interpreted to be a former excavauon was noted immediately outside the west
end of the main service area (Feature 5, Photo F, Photo G).
3) A disturbance (a trench) with a pipe beneath a patched area ofpavmg (approximately 6 inches
wide closer to the building expanding to I .5 feet wide as it gets to the center of the driveway area)

runs from the comer at the southwest side of the service area to the western property boundary
(Feature 6, Photo H, Photo I).
4) A floor drain runs the length of the main service area (Feature 7, Photo J) and appears Lo intersect
the disturbed area noted in #2 above. A similar drain was observed in a separate bay located in
the southwest comer of the building (Feature 8, Photo K). No drain lo the outside was identified.
5) A pipe in the location of the reported sewer line was noted running east from the northeast corner
of the showroom (under the canopy, Feature 9).
6) A used-oil AST is located at the northwest comer of the service bay (Feature l 0).
7) A natural gas line runs toward North Main Street from the center of the south end oftJ1e building
(Feature 11).
8) Eleven circular metal casings were noted inside ilie main service area (Feature 12, Photo L).
These are interpreted to be the casings of the former hydraulic lift cylinders. Smaller (3-inch
dfameter) casings were observed adjacent to the larger rings, and are interpreted to be possible
hydraulic lines.
9) A circular metal cover was observed under the canopy on the north side of ilie building adjacent
to the area of the former reported hydraulic lift. A concrete patch was noted adjacent to the
former reported hydraulic lift (Feature 13, Photo M). The soil was disturbed beneath it but no
UST was identified.
I 0) No other subsurface anomalies were identified around the 2307 North Main Street building.
11) No USTs were located in the southwest portion of the lot.
2309 North Main Street (detail shop) -GPR in the basement of the building and around the perimeter of
the building.
I) Two pipes run from I.he northwest comer of 2307 North Main Street (main showroom building)
to the souilieast comer of2309 North Main Street (Photo N, Photo 0). The eastern pipe run
(Feature 14) seems to coincide with an apparent drain pipe noted inside the building. This
interpreted drain pipe is cul off approximately 1.5 feet from the floor (Feature 15, Photo P, Photo
Q). The western pipe seems to originate from an interpreted electrical conduit pipe that sticks out
of ilie ground approximately 3 inches (F earure 16, Photo R).
2) An area of patched paving was noted on the western end of the north side of the building (Feature
l 7, Photo S, Photo T). Immediately on the other side of the wall (inside) was a cut-off drain pipe
originating from Lhe floor. A suspected oil-water separator or UST was reportedly noted .. outside
the northern building''.
3) A natural gas line (Feature 18) runs from North Main Street to the southeast comer of the detail
shop building.
4) An AST was noted at the north end of the basement (Feature 19, Photo U). No USTs were
identified in the basement.
5) A wide (2-foot) trench with what is interpreted to be a large pipe or more than one smaller pipes
was noted running from the east side of the detail shop to the sewer system that runs along North
Main Street (Feature 20, Photo V). No other interpreted drains or other subsurface anomalies
were identified around the detail shop building. Previous reports bad stated iliat the drains in this
building exited to the north.

No USTs were identified anywhere investigated; however, the hydraulic lift cylinders are interpreted to
remain in place in the main service area of the 2307 North Main Street building. These cylinders and any
associated piping could contain residual hydraulic fluid.
Five interpreted former UST basins were noted -one on the north side of the 2309 North Main Street
buildfog. one to the southwest of the southwest comer of the 2307 building, one under the canopy on the
north side of the 2307 North Main Street building and two on the south side of the 2307 North Main
Street building.
Drums of cleaning compounds and automotive fluids were observed in the service areas of both buildings.
Other than poor housekeeping around the drums (drips and small spills), the drums were not observed to
be leaking.
