City of Pleasanton–Spotorno Ranch Reduced Development Project Initial Study/Consistency Checklist Environmental Checklist FirstCarbon Solutions 109 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480021/Consistency Checklist/21480021 Spotorno Ranch Consistency Checklist ScreenCheck.docx a) Routine Transport, Use, or Disposal of Hazardous Materials Would the project: Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? The 1998 HVSP FEIR determined that proposed development of a golf course within the HVSP area could increase the volume and types of hazardous materials transported, stored, and used on-site or from hazardous materials that are stored in aboveground or underground storage tanks. The 1998 HVSP FEIR determined that enforcement of the applicable statutes and regulations will protect against significant hazardous materials impacts resulting from project development and operation. Additionally, the 1998 HVSP found that the use, transport, storage, or handling of diesel-powered equipment, diesel fuel, motor oils, lubricants, or other hazardous materials, paints, and curing agents may occur during project construction. According to the 1998 HVSP FEIR, the Specific Plan requires preparation of a Spill and Pollution Prevention Plan for each development project with soil disturbance (e.g., grading of at least 5 acres) to mitigate against adverse impacts related to incidents involving hazardous materials during construction. The 1998 HVSP FEIR required MM I6, which would require a Spill and Pollution Prevention Plan to be prepared prior to the issuance of a grading permit for each development project. The 1998 HVSP FEIR concluded that the HVSP regulation of planning, demolition, and construction activities would reduce potential impacts related to hazard oils materials to a less-than-significant level. Short-term Construction Impacts During the construction of the residential development and related infrastructure, small quantities of hazardous materials such as such as gasoline, diesel fuel, lubricants for machines, and other- petroleum-based products would be used on-site. Removal and disposal of hazardous materials from the project site would be conducted by an appropriately licensed contractor. Any handling, transporting, use, or disposal would comply with applicable laws, policies, and programs set forth by various federal, state, and local agencies and regulations, including the United States Environmental Protect Agency (EPA ), Resource Conservation and Recovery Act (RCRA), and City of Pleasanton Chapter 9.21 regarding construction and demolition debris. The proposed project would comply with MM I6 to prepare a Spill and Pollution Prevention Plan. Required compliance with applicable hazardous material laws and regulations would ensure that construction-related hazardous material use would not result in significant impacts. Long-term Operational Impacts During the operational phase of the proposed project, hazardous materials may be utilized on the project site. Because of the nature of the proposed project, hazardous materials used on-site may vary, but would likely be limited to fertilizers, herbicides, pesticides, solvents, cleaning agents, and similar materials used for daily residential operations and home and yard maintenance activities. These types of materials are common for residential developments such as the proposed project and are subsequently regulated by the EPA to minimize harm to people and the environment. Therefore, compliance with the EPA regulations would ensure that operational hazardous material use would not result in significant impacts.
