Draft Environmental Impact Report Bernal Property Phase II Specific Plan (3) Transport, Use, Storage, and Disposal of Hazardous Materials during Site Development Environmental Issues Hazardous materials (e.g. fuels, lubricants, paints, adhesives) would be transported to and used on site for proposed site construction activities. In addition, construction vehicles would be used on the site that could accidentally release hazardous materials, such as oils, grease, or fuels. It is likely that these hazardous materials would be stored by the contrac- tor(s) onsite during the duration of construction activities. Accidental releases of hazardous materials could impact soil and/or groundwater quality, or could result in adverse health effects to construction workers, the public, and the environment. Mitigation Measures Built Into the Specific Plan As required under existing regulations under the Clean Water Act and the N PDES program, preparation and implementation of a Storm Water Pollution Prevention Plan (SWPPP) would be required to minimize potential impacts to the environment during grading and construction activities within the Plan Area. The requirements of the SWppp are detailed in the Infrastructure: Drainage and Water Quality section of this DEIR. Although the primary goal of the SWPPP is to protect stormwater quality, the SWPPP would also serve to mitigate potential hazardous materials releases that could affect construction workers, the public, and the environment. Best Management Practices for the project would include requirements for hazardous materials storage during construction to minimize the potential for releases to occur. All use, storage, transport, and disposal of hazardous materials during construction activities would be performed in accordance with existing local, state, and federal hazardous materials regulations, including Pleasanton's Hazardous Materials Storage Permit Ordinance. The grow-in period for new turf grass often requires higher than normal use of fertilizers and pesticides. These materials could leach into surface water during the latter phases of site construction and affect the public and the environment. The City of Pleasanton has estab- lished procedures and practices in accordance with state and county laws and regulations in regard to proper pesticide mixing, loading, application, and use. City staff17 note that: . Runoff will be conveyed to a detention basin where (as is the case with runoff from nearby residences) potentially toxic substances will be able to vaporize or settle out. City turf management utilizes an irrigation programming system that minimizes irrigation water runoff by programming only the amount of irrigation water that was lost through the previous day's evapotranspiration. Pesticide and fertilizer use is limited to what the law and the labels allow. . . 26 Lisa Hagopian, City of Pleasanton, e-mail communication to Mundie & Associates, December 2, 2005. 84
