City of Pleasanton 2023-2031 (6th Cycle) Housing Element Update CEQA Findings of Fact and Statement of Overriding Considerations FirstCarbon Solutions 105 Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480022/FOF/21480022 Pleasanton Housing Element FOF.docx for lead and asbestos are set forth in Title 8. Title 17 of the California Code of Regulations establishes regulations relating to use and disturbance of materials containing naturally occurring asbestos. Soil excavated during construction is regulated under Title 22 of the California Code of Regulations. The local CUPA is responsible for ensuring that the California Code of Regulations and all other programs related to hazardous materials are implemented during construction activities. Future development that disturbs 1 acre or more of soil, or that is part of a common plan of development that disturbs 1 acre or more of soil, must obtain permit coverage under the Construction General Permit by filing a Notice of Intent (NOI) and Storm Water Pollution Prevention Plan (SWPPP) with the RWQCB prior to commencement of construction. Given documented release sites are within 0.5 of the potential sites for rezoning, there is potential for contamination at several sites. Mitigation Measure (MM) HAZ-2 requires the preparation of a Phase I Environmental Site Assessment (Phase I ESA) and Phase II ESA (as necessary) for review and approval by the City and completion of any necessary remedial activities to be conducted under the oversight of the appropriate regulatory agency. MM HAZ-2 would comply with the public health and safety requirements included in the Vineyard Avenue Corridor Specific Plan relating to construction for Site 27 (PUSD-Vineyard) pursuant to subsection (a). Because significant agricultural operations have existed on Site 27 (PUSD-Vineyard), an inventory of the interior areas of all on-site agricultural structures would be conducted by an environmental professional prior to their demolition, and monitoring by an environmental professional during the removal of floors/foundation would be conducted to determine whether hazardous materials spills are present or suspected to have occurred in these areas, and a report would be provided to the City documenting the findings as required by subsection (b). Development on Site 27 (PUSD-Vineyard) would comply with subsection (c), regulating spills and pollution, subsection (d), regulatory aboveground or underground fuel tanks, subsections (e) and (f), regulating demolition of structures, and subsection (g) regulating the obtaining of information related to possible underground utilities. During operation, hazardous materials used on-site would likely be limited to small quantities of fertilizers, herbicides, pesticides, solvents, cleaning agents, and similar materials used for daily residential and commercial operations and maintenance activities. These types of materials are common for residential and commercial developments and represent a low risk to people and the environment when used as intended. Compliance with applicable plans and regulations, including General Plan goals and policies, including, but not limited to, Goal 5 and Policies 17 and 19 of Chapter 5, Public Safety Element, as described in more detail in Impact HAZ-1, as well as applicable policies of the Vineyard Avenue Corridor Specific Plan, would provide public and environmental protection from reasonably foreseeable upset and accident conditions involving the likely release of hazardous materials during project operation. Ground-disturbing activities associated with development consistent with the Housing Element Update could lead to the rupture of a PG&E or other pipelines if there is not proper coordination with utility owners. Prior to the start of construction activities, developers and their contractors would be required to coordinate with the City’s Operations Services Department and utility owners through notification of the Underground Service Alert system to precisely locate any subsurface utilities (Draft Program EIR, Page 3.8-29–31).
