<br />a description of the sources, and a radius map showing the location of reported facilities relative
<br />to the project Site are attached in Appendix B.
<br />The purpose of the records review was to obtain reasonably available information to help
<br />identify Recognized Environmental Conditions. Accuracy and completeness of record
<br />information varies among information sources, including government sources. Record
<br />information is often inaccurate or incomplete. The Environmental Professional is not obligated
<br />to identify mistakes or insufficiencies or review every possible record that might exist with
<br />respect to the Site. The customary practice is to review information from standard sources that
<br />is reasonably ascertainable within reasonable time and cost constraints.
<br />4.1.1 On-Site Database Listings
<br />AT&T California, Pacific Bell Telephone Company was identified at the Site address on the
<br />CERS Haz Waste, CUPA Listings, CERS, FINDS, RCRA-LQG, ECHO, EMI, HAZNET, HWTS
<br />databases, which contain data extracted from hazardous waste manifests received by the
<br />DTSC each year. The Site obtained an EPA ID number in 1982 and reportedly generated
<br />between approximately 0.02 tons and 0.25 tons of organic and inorganic solids annually, which
<br />was transported off-Site for disposal. In 2018, the Site reportedly generated 0.69 tons of
<br />asbestos waste that was transported to a landfill. In 2009, approximately 1.668 tons of oil-
<br />containing waste was discharged to the sanitary sewer. Periodic compliance evaluation records
<br />were noted to be performed by Livermore-Pleasanton Fire Department. No violations were
<br />reported.
<br />Such listings are common for commercial facilities and are not considered to be indicative of
<br />Recognized Environmental Conditions in connection with the Site.
<br />4.1.2 Adjoining Property Database Listings and Nearby Spill Incidents
<br />Amador Valley High School (1155 Santa Rita Road), located adjacent to the south of the Site,
<br />was listed on the LUST, Alameda County CS, CERS Haz Waste, SWEEPS UST, HIST UST,
<br />Cortese, CUPA Listings, HIST Cortese, and CERS databases due to the removal of a UST in
<br />1992. The leaking UST reportedly impacted soil and the case was closed by the Water Board in
<br />1997. Although the specific location of the leaking UST was unable to be determined (no maps
<br />included on the Water Board’s Geotracker database), based on a review of aerial photographs,
<br />the closest possible location for the former UST (south of the football stadium, tennis courts,
<br />and baseball field) is at least 500 feet south of the Site boundary. A leak that primarily impacts
<br />soil is unlikely to migrate and significantly impact the Site.
<br />Multiple adjoining properties, including dentist offices and the Pleasanton Aquatic Center were
<br />identified as users or generators of small quantities of hazardous wastes (including
<br />photochemical wastes) on regulatory agency databases. No violations were reported, with the
<br />exception of the Pleasanton Aquatic Center, who failed to file a Hazardous Materials Business
<br />Plan but returned to compliance in 2017.
<br />Additionally, based on the information presented in the agency database report, no off-Site spill
<br />incidents were reported that appear likely to significantly impact soil, soil vapor or groundwater
<br />beneath the Site. The potential for impact was based on our interpretation of the types of
<br />incidents, the locations of the reported incidents in relation to the Site and the assumed
<br />groundwater flow direction.
