City of Pleasanton—Villages at the Quarry Project 15183 Consistency Checklist Consistency Checklist 133 petroleum products into structures, the ground, groundwater, or surface water. The Phase I ESA identified several potential Recognized Environmental Conditions (RECs) associated with the project site; however, the Phase I ESA concluded that only one REC was present at the project site. Records that were reviewed by Cameron-Cole indicate hydrocarbon- impacted soils were previously documented in the southeastern portion of the project site. Remediation was performed at this area and a cleanup goal was achieved. Additional records indicate the presence of petroleum and polychlorinated biphenyl (PCB)-impacted soil in surface and subsurface samples at concentrations above acceptable environmental screening levels (ESLs). Groundwater samples collected also identified limited groundwater impacts. Vertical and lateral petroleum hydrocarbon impacts have been identified in the vicinity of the subsurface “silo” area. The Phase I ESA concluded that the presence of soil and groundwater impacts at the project site above acceptable ESLs constitutes a REC at the project site. The presence of a REC at the project site constitutes a potentially significant impact. Because of the identified REC at the project site, further investigation and remediation would be required at the project site. As discussed above, the Housing Element Update FEIR identified MM HAZ-2, which required 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 documentation from the applicable overseeing agency would be required prior to receiving a certificate of occupancy. A Removal Action Completion Report 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 effectively removed and residual concentrations are below DTSC-approved Removal Goals. The DTSC issued a Removal Action (RA) Certification Form on September 4, 2024 (Appendix F). As the form details, the DTSC has determined that all
