3. Environmental Checklist San Leandro Treatment Wetland IS/MND 3-38 February 2024 3.10. Hazards and Hazardous Materials ISSUES: HAZARDS AND HAZARDOUS MATERIALS POTENTIALLY SIGNIFICANT IMPACT LESS THAN SIGNIFICANT WITH MITIGATION INCORPORATED LESS THAN SIGNIFICANT IMPACT NO IMPACT Would the Project: a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? ☐ ☐ ☒ ☐ 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? ☐ ☒ ☐ ☐ c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? ☐ ☐ ☒ ☐ d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code § 65962.5 and, as a result, would it create a significant hazard to the public or the environment? ☐ ☐ ☐ ☒ e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard or excessive noise for people residing or working in the project area? ☐ ☒ ☐ ☐ f) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? ☐ ☐ ☐ ☒ g) Expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving wildland fires? ☐ ☐ ☐ ☒ Discussion a) Transport, Use, and Disposal of Hazardous Materials: During construction of the Proposed Project, including grading and excavation and filling, hazardous materials like fuels, oils, lubricants, and solvents may be used in limited quantities during heavy equipment operation. Mishandling or improper disposal of these materials could lead to accidental releases, posing risks to workers, the public, and the environment, including soil and water sources. However, laws and regulations, such as those enforced by the California Occupational Safety and Health Administration (Cal/OSHA) and the Department of Transportation (DOT), oversee the transport, use, storage, handling, and disposal of hazardous materials, mitigating potential hazards. The construction-phase SWPPP shall incorporate BMPs to regulate hazardous material use during construction, further controlling potential impacts. Examples include the deployment of spill response kits during all construction activities, the establishment of exclusion buffers to restrict access to
