City of Pleasanton—Villages at the Quarry Project Consistency Checklist 15183 Consistency Checklist 132 groundwater-based materials into the environment during site grading and excavation operations. However, development of the rezoned housing sites is not expected to result in the transport, use, storage, or disposal of substantial amounts of hazardous materials, with the exception of common residential and commercial-grade hazardous materials such as household cleaners and paint, among others. Several documented release sites are within 0.5 mile of the rezoned housing sites (see Housing Element Update FEIR Table 3.8-1 and Exhibits 3.8-1a and 3.8-1b). Construction activities at these sites would likely involve ground- disturbing activities that could expose workers, the public, and the environment to contaminated soil and groundwater, if present. The Housing Element Update FEIR concluded that compliance with applicable federal, State, and local laws, plans and regulations, including the General Plan, Titles 8 and 17 of the California Code of Regulations, California Division of Occupational Health and Safety (Cal/OSHA) requirements, as well as implementation of MM HAZ-2, which requires the preparation of a Phase I Environmental Site Assessment (Phase I ESA) and Phase II ESA (as necessary) and completion of any necessary remedial activities to be conducted under the oversight of the appropriate regulatory agency, would provide public protection from hazards associated with the use, transport, treatment, and disposal of hazardous substances during construction and operation of development consistent with the Housing Element Update. Therefore, impacts related to upset and accident conditions involving the release of hazardous materials into the environment would be less than significant with mitigation. Proposed Project Analysis and Conclusion As discussed above, the Housing Element Update FEIR indicated that several of the rezoned housing sites are located near identified contamination sources that have not been fully remediated. MM HAZ-2 was included in the Housing Element Update FEIR, which required the preparation of a Phase I ESA for sites affected by these areas. A Phase I ESA was prepared on March 11, 2022, by Cameron-Cole for the proposed project (Appendix F). The goal of the Phase I ESA is to identify the presence (or likely presence) of hazardous substances or petroleum products at the project site, under conditions that indicate an existing release, a past release, or a material threat of release of any hazardous substances or
