III. Environmental

Current Use of Property: Commercial/Retail
Structures on Property: Existing Structures Violation: No

Vapor Mitigation Systems: Observed Vapor Mitigation Violation: No

Use of Surface Water or Groundwater: Not Observed Water Use Violation: No

Exposed Soils: Not Observed Exposed Soils Violation: No

Summary: Observed VIMS panel repair (vacuum tubing repaired on rooftop since last site
visit). Observed VIMS risers; however, did not climb onto roof on exposed rooftop ladder
due to safety concerns during steady rain.

Summary: N/A

Summary: Single story masonary construction former Fleming Laboratories building has
been retrofitted into two brewery type facilities. Summit Seltzery (currently operating), is
located within the northern portion of the building, and Midnight Mulligan Brewing, a
brewery/restaurant is located in the southern portion of the building.

Use of Basements: Not Observed Basement Violation: No

Storage of Chemicals: Not Observed Chemical Violation: No

Groundwater Monitoring Wells: Not Observed Monitoring Well Violation: No

Current Exposure to Public/Public Risk:

Summary: N/A

Summary: N/A

Condition:
Summary: N/A

Although no public risk to the public was observed during operation of VIMS, some floor
slab cracking was observed and at least one floor penetration observed during the Site
Inspection (photos 5 and 6 respectively. If a blower were to shut down, these and other
locations could be potential VI pathways to indoor air. These floor slab cracks and
penetrations will be addressed by Terracon, with photo documentation to be provided to
DEQ Brownfields.

IV. Inspector Comments

V. PHOTOGRAPHS

Photo 1: VIMS control panel indicating that Blower #4 is operational (Magnahelic gauge on
lower right). Terracon personnel reattached Blower 4 rooftop suction tubing since the most
recent Site Inspection.

Site reinspection performed following October 12, 2021 site visit in which VIMS control
panel seemed to indicate that Blower 4 was not operational, and it was not clear that all
of the issues identified in Terracons Sub-Slab Modification and Evaluation report had
been adequately addressed. Following the Site Reinspection, It was determined that the
items of concern were addressed; however, several additional item were observed
(labeling and floor penetrations described below), that will need to be addressed.

Photo 4: Based on conversations with Mr. McElveen, Clean Vapor is no longer associated with
this project. Requested that new labeling with current site contact be installed on VIMS risers
over existing labels

Photo 5: Floor slab crack that has occurred since original floor sealing performed. Requested
that additional sealing be performed to address potential VI preferential pathways.

Photo 6: Using smoke pen to check former utility line conduit hole in floor slab. Smoke was
hard to observe, but active VIMS was able to pull flame into hole, confirming connectivity of
sub-slab with indoor air. Requested that all floor slab penetrations be caulked to address
potential VI pathways.
