However, it was determined that development facilitated by the Housing Element would comply with all applicable regulations for management of hazardous materials during the construction phase of development. These policies include Title 22 and 26 of the California Code of Regulations governing hazardous material transport, Title 8 Standards for handling asbestos and lead during demolition/construction, and Title 19 of the California Code of Regulations and Chapter 6.95 of the Health and Safety Code for site remediation. In addition to the hazardous materials risks noted above, the Prior EIR recognized that new residential development may routinely use commonly available hazardous substances, like fuels, lubricants, and household cleaners. However, it was determined that home use of common household hazardous materials typically consists of limited quantities and is generally considered to be an acceptable risk to the environment. Lastly, the Prior EIR recognized that demolition of existing structures on the potential sites for rezoning could release other hazardous materials, such as asbestos and lead-based paint, and expose construction workers, the public, or the environment to hazardous materials. However, the Prior EIR identified measures established by the Clean Air Act and enforced by the Occupational Safety and Health Administration (OSHA) that certified contractors are required to use to contain, store, and dispose of these hazardous materials in a manner which limits exposure. Therefore, due to a limited potential for exposure of the people or the environment to hazardous materials, largely as a result of compliance with federal, State and local regulations, the Prior EIR found that impacts related to the routine transport, use, or disposal of hazardous materials would be less than significant. Analysis of Proposed Project The proposed project may utilize hazardous materials such as fuels or solvents during the construction phase of the project. During the operations phase, residents may also routinely use commonly available hazardous substances, like fuels, lubricants, and household cleaners. As discussed above, potential hazards arising from the transport, use, and disposal of these hazardous materials would be minimized and regulated in accordance with local, State, and federal policies, regulations, and standards. Impacts would continue to be less than significant, and no mitigation is necessary, consistent with the Prior EIR. There are no proposed changes, new circumstances, or new information that would cause new or more severe impacts. Therefore, there are no environmental effects that are peculiar to the proposed project or the parcels on which the proposed project would be located. Impacts would be less than significant and the proposed project would not result in a new or more severe adverse impact that was not previously identified in the Prior EIR. b) Hazardous Material Upset or Accident Prior EIR Conclusions The Prior EIR found that construction of residences on the Housing Element’s potential rezoning sites would disturb soils that could be contaminated from past releases of hazardous substances into the
