III. Environmental

Current Use of Property: Residential
Structures on Property: Existing Structures Violation: Unknown

Vapor Mitigation Systems: Observed Vapor Mitigation Violation: Yes

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

Summary: While on-site, confirmed that at least one operating VIMS discharge riser exits
the northern side of the apartment building approximately four feet above grade, and
discharges towards sidewalk located approximately 5 feet from side of the apartment
building (Photos 1 and 2).

The VIMS exhaust location is a violation of several requirements within CC-1000 Soil Gas
Control Systems In New Construction of Buildings including but not limited to;
• The point of exhaust shall not be located less than 10’ above grade.
• In relationship to exterior flooring surfaces (which includes sidewalks) the point of
exhaust shall be not less than 10 feet horizontally to the side of exterior flooring
surface, and the point of exhaust shall be compliant with directional spread
requirements (exhaust gas must not be vented in a downwards trajectory).

Temporary pilot-test barriers/piping set-up observed within atrium and adjacent
apartments although not currently in use (Photos 3-6).

Summary: N/A

Summary: Existing mill building renovated for multi-residential apartments. Leasing
manager not available during site visit. It is unclear if there are currently tenants within
units that are not currently approved for occupancy.

areas, common hallways, residential units, and an atrium that are at least partially below
the surrounding grade”.

IV. Inspector Comments

V. PHOTOGRAPHS

Photo 1: VIMS galvanized steel exhaust piping from crawlspace on left side of photo.

The purpose of this inspection was to determine the occupancy and mitigation status of
site building 12-15. Repeated requests for information from the Brownfields PMU group
to the developer have gone unanswered and there are public health concerns associated
with the site building. The leasing agent was not present at the facility during the Site
Inspection, so occupancy data for the western building, and access to the roof-top VIMS
fans was not obtained during the site inspection.

As discussed in the previous Vapor Mitigation Section - photos of a VIMS exhaust
discharge exiting side of building, and temporary pilot test barriers and partial piping still
installed within atrium and adjoining ground floor apartments installed by Geosyntec
were taken.

Photo 2: VIMS exhaust discharge in vicinity of sidewalk. The VIMS discharge is approximately
four feet off the ground and the exhaust airflow is angled downwards approximately 45° due to
the backdraft damper visible in the photo.

Photo 3: Pilot test barrier with interior suction piping at entrance to atrium (only one side of
entrance shown). Suction pipe exiting end of barrier most likely plumbed together using PVC
piping shown in Photo 6 during pilot testing and discharged out of building.

Photo 4: Wood support colums within center of atrium. Similar temporary barrier with PVC
suction pipes exiting the barriers.

Photo 5: Pilot test barrier covering floor/wall junction on left side of photo. PVC piping crossing
doorway within apartment unit interconnects the two barrier sections.

Photo 6: PVC piping stored within ground floor atrium apartment. Most likely disassembled
pilot test piping used to interconnect piping exiting barrier during testing.
