ITEM 23 ATTACHMENT 1 - CEQA Checklist

City of Pleasanton—Merritt Property Project 15183 Consistency Checklist Consistency Checklist 119 West Environmental Services and Technology, Inc. prepared a Closure Evaluation for the proposed project site on October 9, 2023 (Appendix F). The Closure Evaluation determined that the chemicals present at the project site do not pose an unacceptable threat to human health based on a residential land use exposure scenario and that no further actions to address conditions were required. Therefore, the RWQCB concluded that the project site can remain a closed site and no further action or evaluation is required.19 Based on this evaluation, no Phase I ESA would be required for the proposed project pursuant to Housing Element Update FEIR MM HAZ-2. As discussed in the Housing Element Update FEIR, to prevent and minimize hazardous conditions to below a level of significance, existing local, State, and federal law would be enforced. Compliance with existing regulations would ensure that construction workers and the public are not exposed to any risks related to hazardous materials during demolition and construction. The proposed project would comply with Cal/OSHA regulations concerning the use of hazardous materials, including requirements for safety training, exposure warnings, availability of safety equipment, and preparation of emergency action/prevention plans. All contaminated waste would be collected and disposed of at an appropriately licensed disposal or treatment facility. Environmental effects would be avoided by the imposition of uniformly applied development policies or standards. As such, there are no environmental effects that are peculiar to the proposed project. The proposed project would not result in a new or more severe adverse impact that was not previously identified in the Housing Element Update FEIR. c) Hazardous Emissions Proximate to a School Would the project: Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? Summary of Housing Element Update FEIR The Housing Element Update FEIR indicated that there are schools within 0.25 mile of the rezoned housing sites. However, use of hazardous materials during construction and operation of the sites would not result in the handling of significant quantities of hazardous materials, substances, or wastes, and such 19 McCaulou, Cherie.
