City of San Leandro 2824 Halcyon Drive Residential Project 64 a. Would the project create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? Residential land uses typically do not use or store large quantities of hazardous materials. As such, the proposed project would not involve the use, storage, transportation, or disposal of significant quantities of hazardous materials. In the event that hazardous materials are used or otherwise handled on the project site, use, storage, and disposal of hazardous materials are regulated through the Resources Conservation and Recovery Act (RCRA) as well as the California Hazardous Waste Control Law (California Health and Safety Code Division 20, Chapter 6.5) and the Hazardous Waste Control Regulations (Title 22, CCR, Divisions 4 and 4.5). In addition to state regulations, the project site’s use of hazardous materials would be regulated pursuant to federal, state, and local laws as noted in the General Plan EIR. With implementation of General Plan Policies EH-5.1 and EH-5.6 which focus on coordinated hazardous waste programs and regulatory compliance and educating the public about the safe disposal of hazardous waste, impacts related to the use, storage, transportation, and disposal of hazardous materials at residential land uses would not pose a significant risk to human health or the environment. Transport and use of such materials would be subject to all applicable state and federal laws, such as Hazardous Materials Transportation Act, RCRA, the California Hazardous Materials Management Act, and the California Code of Regulations, Title 22. Therefore, this impact would be less than significant. b. Would the project 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? As mentioned under criterion a, the project would not use, store, or otherwise deal with substantial quantities of hazardous materials. As the project would not store large quantities of hazardous materials on-site, the project would not create conditions that could lead to the release of substantial amounts of hazardous materials. In addition, implementation of General Plan Policies EH-5.3 and EH-5.6, and Action EH-5.6A which focuses on the safe storage of hazardous materials and educating the public about the safe disposal of household hazardous waste, would reduce impacts related to the accidental release of hazardous wastes on the project site during project operation. The Limited Phase II ESA revealed that various concentrations of herbicides, total petroleum hydrocarbons (TPH), volatile organic compounds (VOCs), and polycyclic aromatic hydrocarbons (PAHs) were reported in soil samples at levels below their applicable San Francisco Bay Regional Water Control Board (RWQCB) Residential Environmental Screening Levels and/or EPA Regional Screening Levels. Although organochlorinated pesticides (OCPs) alpha-BHC 3 and dieldrin 4 were detected in shallow soil samples at concentrations that exceeded the EPA Regional Screening Levels and RWQCB Residential Environmental Screening Levels, respectively, compliance with CO HAZ-1 and COA HAZ-2 described in Section 12, Best Management Practices, of the introductory sections to this document, would reduce impacts to a less than significant level by requiring preparation of a Soil Management Plan for impacted soils as well as conducting remediation for soils with concentrations of chemicals exceeding hazardous waste screening thresholds. As stated in the Limited Phase II ESA, soils containing OCP alpha-BHC and dieldrin would be removed prior to 3 OCP alpha-BHC is a type of highly toxic, non-specific organochlorine insecticide used for a variety of agricultural applications. 4 Dieldrin was used as an insecticide from the 1950s to 1970 and was used as a pesticide for corn, cotton, and citrus crops. It has since been banned due to its highly toxic nature and its ability to increase in concentration in each step of the food chain (Honeycutt and Shirley 2014).
