IV. Inspector Comments

V. PHOTOGRAPHS

Photo 1: Former trolley barn building which has been converted into a brewery. Photo taken
facing north.
The purpose of the Site Inspection was to inspect the VIMS, including the state of
completion of the currently un-used suction point R-4 prior to building occupancy.

The portions of the VIMS that were visible matched as-built drawings provided by WOOD
in their June 25, 2021, Request for Occupancy – Trolley Barn Building except for the two
roof top risers which were not properly labeled. Labeling of these two risers was
performed during the inspection. One other item of concern was the condition of the
concrete around Monitoring Point 2 where cracking and gaps around the vault were
present (Photo 5).

At the conclusion of the inspection, Mr. Hanley and Mr. Horsley brought up their
concerns with additional sub-slab and IA sampling requested by DEQ, and I let them know
I would communicate their concerns to the PM.

Photo 4: VIMS suction point R4 stubbed-up and capped. It was determined based on vacuum
influence measurements that this riser was not necessary.

Photo 5: Monitoring point MP-2 where a crack in the concrete and a gap around the brass vault
was observed. The VIMS spray barrier is sealed to PVC monitoring point; therefore, the vault
and concrete crack are located above the VIMS barrier.
