3.0 ENVIRONMENTAL CHECKLIST 1388 Bancroft Avenue Project City of San Leandro Initial Study/Mitigated Negative Declaration November 2018 3.0-44 the remaining portion of the site contained a residence. Circa 1980, the remaining residence was removed, and its area converted into a parking lot. The Phase I ESA did not identify any Recognized Environmental Conditions (REC) or Historical RECs. Other environmental considerations identified in the report include the potential presence of lead- based paint and asbestos-containing material (ACM), due to the age of the existing buildings. Mold growth was also observed in the existing buildings on the project site. Finally, the gas station to the northwest of the project site, at 1285 Bancroft Avenue, is listed in the Alameda County LOP and LUST [local oversight program and leaking underground storage tank] database for identified pollution related to automotive gasoline pollution, affecting both soil and groundwater. Based on the case closure status of this listing and the hydrologic gradient flowing away from the project site, the Phase I ESA concluded that the 1285 Bancroft property does not represent a significant environmental concern for the proposed project (AEI Consultants 2015). CHECKLIST DISCUSSION a) Less Than Significant Impact. Project construction would involve the routine transportation, storage, use, and disposal of small quantities of hazardous materials such as construction equipment fuels and lubricants, hydraulic fluid, and solvents. The storage and handling of these materials would be managed in accordance with applicable state and federal laws for safe handling of hazardous substances, which include developing project-specific hazardous materials management and spill control plans, storing incompatible hazardous materials separately, using secondary containment for hazardous materials storage, requiring the contractor to use trained personnel for hazardous materials handling, and keeping spill cleanup kits available on-site. Routine transport, storage, use, or disposal of hazardous materials during construction would not create substantial hazards to the public or the environment. The project would consist of residential uses. During operation, no use or storage of hazardous materials would be expected beyond cleaning and landscaping chemicals. Therefore, impacts would be less than significant. b) Less Than Significant Impact with Mitigation Incorporated. Demolition of the existing buildings on the project site could result in the airborne release of hazardous building materials, such as asbestos fibers or lead dust. However, compliance with federal and state laws requires inspection and removal of hazardous building materials, including asbestos-containing materials and lead-containing substances. If asbestos and lead are found in building materials removed, abatement practices such as containment and removal would be required prior to demolition, as identified in mitigation measure MM HAZ-1. In addition, the project applicant would be required to obtain clearance for asbestos removal from the BAAQMD prior to issuance of a demolition permit. Therefore, due to existing regulations and through implementation of mitigation measure MM HAZ-1, the potential for public health hazards associated with the release of airborne asbestos fibers or lead at the project site would be considered less than significant. No other project-related processes or operations would create reasonably foreseeable upset and accident conditions involving the release of large amounts of hazardous materials into the environment. Fluorescent lights and materials containing polychlorinated biphenyls (PCBs) would be handled and disposed in accordance with applicable state and federal regulations. Hazardous materials used during construction, such as fuel for construction equipment and vehicles, would be managed in accordance with applicable laws and regulations as described in checklist item a) above.
