As planned, site investigations on the location of suspected
underground tanks formerly operated by the Uestern 
Auto store
located 'at Four 
Uinds .-Plaza , .8392 :Anna's Retreat, St Thomas
continued this week. 'Following your suggestion, ;I continued the
effort "to locate 
the UST '•;-•.•• near ithe Western Auto repair bays,
reportedly used 
for diesel 
fuel storage - :for • the .Uestern Auto
generator. Ue also investigated the cap protruding from the ramp
area located to the north and west of the Uestern Auto repair
bays .
The site investigation proceeded utilizing similar investigative
methods and quality control/quality assurance as described in my
letter of'Nov: 28, 1992:
Generator Room: The cap that protrudes from the ramp located
a:.
the northwest corner of the area was removed.
A probe was
inserted into the opening. 
The apparent tank was filled with
i-^r-cJ and is approximately (appx . ) 5 feet (ft.), two inches deep.

Located 17 ft North and 10 ft. west of the first bay
(appx. halfway between the wall and TU-3). Drilled to refusal at
30 
inches. 
A brown-gray clay was encountered with a slight
hydrocarbon odor. Samples were taken for TRPH, oil and grease,
and EPA analyses 8010, 8020 and 8100.
3. TU-5: 
Located 17 ft. north and 6 ft. west o' the first bay.

4. Tank *2: 
An apparent vent had been located at the southeast
corner of the existing above-ground diesel tank that stands in -a
concrete containment wall north of the bays. A trench was dug in
the southeast corner of the containment wall where copper and pvc
conduit were found. There appeared to be an old vent and/or fuel
lines leading to the southwest. 
The lines were traced to a
location appx. 11 ft. west and .12 ft. north of the first bay.
Upon further .excavation a 2 "ft. X 2 f t. opening was created. A
metal fitting was found with a copper line running back to the
building. This fitting was removed. 
A probe was inserted into
the tank. The tank appears to be three ft. deep. . It contained
appx. 2.5 ft. of hydrocarbon or 
hydrocarbon-like product.
Further excavation to determine the size of the tank and sampling
to determine the contents of the tank will be performed the week
of Dec. 7, 1992.
Mr. Crooke was called at the St. Thomas-DPNR -office on Friday,
December 7, 1992.: "I reported -the findings of my'investigation to
date. Further investigations are planned for the week of Dec. 6,
1992. Please contact me with any questions or- comments. """•
