Phase I Environmental Site Assessments
CORE performed Phase I Environmental Site Assessments (ESAs) for
the properties located at 21 S. Ryan Street and 245 Dearborn Street in
Buffalo, New York for the purposes of potential property transactions.
The Phase I ESAs were performed to identify recognized environmental
conditions (RECs), historical recognized environmental conditions
(HRECs), controlled recognized environmental conditions (CRECs),
and/or potential environmental concerns (PECs) in association with the
target properties or adjacent/nearby properties. The ESAs were performed
in accordance with ASTM International (ASTM) and United States
Environmental Protection Agency (USEPA) guidelines and statutes. In
addition, CORE was asked to prepare Health and Safety Plans (HASPs)
for each property prior to completing any on-Site activities. The contract
also required surveys for lead-based paint (LBP) and asbestos-containing
materials (ACMs) at the properties, as well as ASTM-compliant mold
surveys and Vapor Encroachment Screens (VES).
CORE performed a records review, utilizing an Environmental Data
Resources, Inc. (EDR) Report to determine the presence of any
environmental liabilities associated with the property. In addition, CORE
reviewed aerial photographs, Sanborn Fire Insurance Maps, historical
topographic maps, and City directory abstracts describing historical uses
of the target properties and adjacent/nearby properties.
The Phase I ESA for the property at 21 S. Ryan Street identified a REC
in the form of possible groundwater impacts and soil vapor intrusion
issues from an upgradient dry cleaning facility that was a known point
source of impacts to the subsurface and soil vapor in nearby residential
areas. As a result, CORE determined that it was likely that a VEC existed
with respect to the target property, causing degraded indoor air quality
(IAQ) in the overlying structure on the property. The results of the
Phase I ESA indicated that a Phase II Environmental Site Investigation
(ESI) should be performed to evaluate the possibility that these impacts
had migrated to the target property. The Phase II ESI would include an
evaluation of soil, groundwater, soil vapor, and IAQ at the Site.
