LISA ASSOCIATES, INC. CEQA INITIAL STUDY/MITIGATED NEGATIVE DECLARATION PARCH 1011 PREDA STREET PIPE BRIDGES UPGRADE SAN LEANDRO. CALIFORNIA According to the California State Water Resources Control Board (SWRCB) Geotracker website (SWRCB 2009), there is one Leaking Underground Storage Tanks (LUST) site and two other clean up sites within 1,000 feet of the project site. The LUST site was at Cherry City Nursery. located at 1034 Peralta Street. The other clean up sites were Electra Engineering Glencoe and Electro Engineering Caloyeras at 399 and 401 Preda Street. respectively. All three clean up sites are closed cases. Discussion: a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? Less Than Significant Impact. No routine transport or disposal of hazardous materials would be associated with the project. While gas and diesel fuel would typically be used by construction vehicles, Best Management Practices (BMPs) would be utilized to ensure that no construction- related fuel hazards occur. All use, storage, transport and disposal of hazardous materials (including any hazardous wastes) during construction activities shall be performed in accordance with existing local, state, and federal hazardous materials regulations. Therefore, implementation of the proposed project would not 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? Less Than Significant with Mitigation Incorporated. As described in Section Vll(a) above. operation of the project would not require routine use of hazardous materials; therefore, no hazards or hazardous materials impacts related to long term operation of the project are anticipated. However, construction activities would include the use of limited quantities of ordinary equipment fuels and fluids. In the unlikely event of a spill, fuels would be controlled and disposed of in accordance with county and state regulations. Implementation of Mitigation Measure HAZ -1 would ensure that handling of materials during construction activities would not create a hazard to the public or the environment, thereby reducing potential impacts to less than significant levels. Mitigation Measure HAZ-1: Project construction plans shall include emergency procedures for responding to hazardous materials releases for materials that shall be brought onto the site as part of construction activities. The emergency procedures shall include specific measures to be implemented in the event of a release of a hazardous material into water or onto land. The Contractor shall be required to have on hand at all times adequate absorbent materials and containment booms to handle a spill equivalent to the largest container of fuels or oil in their possession. In addition, the plans shall describe measures to contain waste water (rinsate) generated from the cleaning of equipment. Rinsate shall not be allowed to be discharged to the ground or to San Leandro Creek but must be contained and disposed of at an off -site location as designated in the plans. c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one- quarter mile of an existing or proposed school?
