City of Pleasanton—Vineyard Avenue Residential Project Consistency Checklist 15183 Consistency Checklist 100 herbicides on-site, any of which could contain potentially hazardous chemicals; however, such products would be expected to be used in accordance with label instructions. Due to the regulations governing use of such products and the amount that would be used on the site, occasional use of such products would not represent a substantial risk to public health or the environment during project operation. Therefore, impacts related to creating a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials were adequately addressed in the Housing Element Update FEIR, and the proposed project would not result in any effects that would require further CEQA review for this topic. b, d) Hazardous Materials Risk of Upset, Hazardous Materials Sites, and Government Code Section 65962.5 Sites Would the project: b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? or d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? Summary of Housing Element Update FEIR The Housing Element Update FEIR indicated that future construction activities would have the potential to release potentially hazardous soils- and groundwater-based materials into the environment during site grading and excavation operations. However, development of the potential sites for rezoning 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 potential sites for rezoning (see Housing Element Update Draft EIR Table 3.8-1 and Exhibits 3.8- 1a and 3.8-1b). In addition, it is noted that Site 22 (Merritt) is a currently inactive Department of Toxic Substances Control (DTSC) site but needs further evaluation regarding previously detected volatile organic chemicals (VOCs) and organochlorine pesticides in soil and groundwater.14 14 California Department of Toxic Substances Control (DTSC). 2022.
