13. Evaluation of the analytical results of the Phase II Assessment by a qualified environmental pro- fessional is required to determine whether chemicals could pose a hazard to future site users, con- struction workers, or the environment. If chemicals at the site could pose a hazard, a qualified pro- fessional shall conduct a risk assessment to quantify hazards based on soil and/or groundwater sampling results, and develop appropriate remediation measures, as necessary, to reduce potential risks for future site users to acceptable levels. Potential remediation measures may include, but not be limited to, soil removal. cupping with an impermeable cover, soil vapor extraction, and groundwater remediation and/or monitonng. Regulatory agency oversight shall be obtained, as appropriate, from a local or State agency. Timing: Prior to approval of grading permits for the Golf Course and Spotorno properties. I4. Completion of an inventory of the interior areas of all on-site agricultural slruetures is required. If hazardous materials are identified as being stored in these areas at that time, those materials shall be transported to and disposed of/recycled at an appropriate off-site facility. Timing: Prior to issuance of de~nolition permits for agricultural structures. 15. Monitonng by an environmental professional dunng the removal of the floors/foundations is required to determine if hazardous materials spills are present or suspected to have occurred in interior areas of on-site agricultural structures (pur~s.u~nt to Requirement 14). After demolition, a report by the environmental professional shall be submitted to the City delineating whether haz- ardous materials appeared to be present below the floors or foundations. If evidence of hazardous materials is found. a soil sampling plan shall be prepared and implemented prior to disturbance of native soils. The soil samples shall be collected by a qualified environmental professional and submitted to a California-certified laboratory for analysis. The analytical results shall be evaluated by a qualified environmental professional for development of an appropriate health and safety plan for construction workers involved in site demolition activities, waste disposal options, and potential site investigation/remediation. Timing: (1) Monitormg for presence of hazardous materials: during removal of ~oors/founda- tions. (2) Report to Ci.ty of whether hazardous materials were foun& after structure demolition. (3) Approval of a Soil Sampling Plan (if necessary): prior to disturbance of native soils. (4) Approval of a health and safety plan (if necessary): prior to new site preparation and construction. I6. Preparation of a Spill and Pollution Prevention Plan must be prepared by the contractor(s) for each development project with soil disturbance (e.g., grading) of at least five acres. The Plan must (1) be prepared prior to the start of earthwork activities, (2) designate an onsite employee responsible for Plan implementation, and (3) include anticipated equipment needs and maintenance, emergency response procedures for hazardous materials releases, and procedures for contacting designated regulatory agencies in the event of a hazardous materials release. Timing: Plan preparation prior to issuance of a grading permit; plan implementation during earthwork and construction activities. 16
