ITEM 23 ATTACHMENT 1 - CEQA Checklist

City of Pleasanton—Merritt Property Project 15183 Consistency Checklist Consistency Checklist 121 and/or remediation work would be required to ensure that construction activities would not expose people or the environment to adverse effects, as required by MM HAZ-2. Therefore, with implementation of MM HAZ-2 and compliance with applicable federal, State, and local laws, as well as compliance with appliable plans and regulations, as enumerated in more detail in Section 3.8, Hazards and Hazardous Materials, in the Housing Element Update Draft EIR, impacts related to the creation of a hazard to the public or environment would be less than significant. Proposed Project Analysis and Conclusion The project site was identified as needing further evaluation regarding previously detected VOCs and organochlorine pesticides in soil and groundwater by the Housing Element Update FEIR. The RWQCB closed the project site in 2003 based on the available data. Additional sampling was conducted in 2007 by Cornerstone to evaluate the data with respect to current California State Water Resources Control Board (State Water Board) Environmental Screening Levels (ESLs). 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.20 Based on this evaluation, no Phase I ESA would be required for the proposed project pursuant to Housing Element Update FEIR MM HAZ-2. Furthermore, the proposed project would comply with applicable local, State, and federal regulatory requirements related to the handling and storage of hazardous materials. Therefore, 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. e) Proximity to Public Airport Safety Hazard Would the project: For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport 20 McCaulou, Cherie.
