City of Pleasanton—Villages at the Quarry Project 15183 Consistency Checklist Consistency Checklist 137 The presence of a REC at the project site constitutes a potentially significant impact. Because of the identified REC at the project site, the Phase I ESA recommended further investigation and remediation at the project site. As discussed above, the Housing Element Update FEIR identified MM HAZ-2, which requires the preparation of a Phase I ESA. Additionally, MM HAZ-2 requires the preparation of a Phase II ESA in the event that further investigation and remediation is needed at the project site. MM HAZ-2 further requires that, prior to receiving a certificate of occupancy, documentation from the applicable overseeing agency shall be issued indicating that all required remediation has been completed and no further action is required. A Removal Action Completion Report (Appendix F) was completed in May 2024, which outlines the remedial excavation activities conducted in accordance with the DTSC-approved RAW for the project site. Remedial excavation activities were performed between February 1, 2024 and March 8, 2024, resulting in approximately 18,231 tons of contaminated soil being transported off-site for disposal. Based on the results from soil samples obtained during remediation as well as post-excavation confirmation sampling, the identified contaminated soils have been removed and residual concentrations are below DTSC-approved Removal Goals. The DTSC issued an RA Certification Form on September 4, 2024 (Appendix F). As the form details, the DTSC has determined that all appropriate response actions have been completed, that all acceptable engineering practices were implemented, and that no further removal is necessary.20 Full compliance with MM HAZ-2 has been achieved with DTSC’s formal approval of the RA Completion Report. Compliance with applicable federal, State, and local regulations regarding hazardous materials, including the Hazardous Materials Transportation Act, California Public Resources Code, and General Plan, would reduce and limit the associated risks. Similarly, any handling, transporting, use, or disposal of hazardous materials during demolition, construction. or operation would comply with applicable laws, policies, and programs set forth by various federal, State, and local agencies and regulations, including, but not limited to, the EPA, RCRA, Caltrans, the LHMP, Title 22 and 26 of the California Code of Regulations governing hazardous materials transport, and Title 19 of the California Code of Regulations and Chapter 6.95 of the Health and Safety Code for site remediation. 20 California Department of Toxic Substances Control (DTSC).
