2.0 EPIVIItONMENTAL CHECKLIST used and stored at the water recycling plant. The proposed tertiary treatment at the WPCP would incrementally increase the amount of sodium hypochlorite stored on site. nrscvssroN a) The proposed water recycling plant at the WPCP would require minor changes to use and transport of hazardous materials. Less-than-significant impacts from routine use, storage, transport, and disposal of chemicals used at the WPCP and the proposed water recycling plant may occur. The water recycling plant proposed at the Monazch Bay Golf Complex for Phase la application, would use and store liquid sodium hypochlorite. Sodium hypochlorite would be transported to the water recycling plant as a 12 percent solution in truck deliveries of up to 4,000 gallons per tank truck. The storage tank would be sided fora 30 day supply which is approximately 1,000 gallons per month. Secondary containment for the storage area would be provided. Chemical metering pumps feed hypochlorite to the point of application. Hypochlorite solution demand is estimated to be 35 gallons per day. The proposed water recycling disinfection and filtration facility at the WPCP would not use additional hazardous chemicals. Measure HM-1 would reduce impacts associated with the use, transport, and disposal of hazardous chemicals. b) An underground jet-fuel line of unknown size, operated by Kinder Morgan, is located between the unused ponds and the San Leandro Slough on the WPCP. Rupture of this pipeline during construction activities could result in a hazardous condition including injury or death to nearby construction and WPCP workers. Implementation of Measures HM-~. and HM-3, requiring consultation with the jet fuel pipeline owner, Kinder-Morgan during design and construction would reduce the potential for accidental breach of the pipeline to aless-than-significant impact. Construction activities would involve the use of certain potentially hazardous materials such as paints, fuels, oils, and solvents. These materials would generally be used for excavation equipment, generators, and other construction equipment, and would be contained within vessels engineered for safe storage. Spills during onsite fueling of equipment or an upset condition (e.g., puncture of a fuel tank through operator error) could result in a release of fuel or oils into the environment. Storage of large quantities of potentially hazardous materials at the construction site is not anticipated; however, the uncontrolled release of these materials would be a potentially signuficant impact. Measures HM-1 and HM-4 would reduce impacts from hazardous materials release to ales-than-significant level. Measure HM-4 requires that a Hazardous Materials Management/Spill Prevention Plan (Plan) be developed and given to all contractors working on the Project. The purpose of the Plan is to provide on-site construction personnel, environmental compliance monitors, and regulatory agencies with a detailed description of hazardous materials management, spill prevention, and spill response/cleanup measures associated with the construction of Project elements. Measure HM-4 requires that the WPCP update the existing Hazardous Materials Business Plan and submit it to the Alameda County Department of Environmental Health. This Plan specifies requirements for storage and disposal, measures for protection of personnel, and procedures to be followed in the event of a spill at times other than construction. This Plan also has drawings depicting the facilities and distribution systems that will be requited to be updated. c) The closest school, Garfield School is located 0.3 miles from the closest location of the proposed pipeline and 0.4 miles from the water recycling plant at the Monazch Bay Golf Complex. As discussed above, with the exception of the small amounts of sodium hypochlorite at the water recycling plant, no hazardous materials would be routinely used during the operation of the San Leandro Recycled Water Project 2-2(7 ESA / 203193 Draft ISMIND
