Mitigation Measure 4.9-1: Agricultural Chemical Use. All vineyard and other agricultural use operators shall notify adjacent landowners at least 24 hours prior to the application of any pesticide sprays or dust. Application of any pesticides by spraying or dusting shall be restricted to periods during which wind speeds are less than 5 miles per hour. Aerial spraying shall not be permitted. Prior to development of Lots 1, 2, 18, 19, 21, 22, 26, 28, 30, and 31, where a nursery or significant agricultural operations now exist or once existed, a Phase I Environmental Site Assessment shall be conducted by a qualified environmental professional in accordance with the requirements of the American Society for Testing and Materials (ASTM 1997). If the findings of the Assessment indicate the presence of, or potential for, hazardous materials use associated with the current or past agricultural uses of these sites, a Phase II Environmental Site Assessment shall be conducted by a qualified environmental professional to ascertain whether past or current land uses have contributed to soil and/or groundwater contamination at the site. Soil and groundwater samples collected during the Phase II Assessment shall be submitted to a California-certified laboratory for analysis. The analytical results of the Phase II Assessment shall be evaluated by a qualified environmental professional to determine whether chemicals could pose a hazard to future site users, construction workers, or the environment. If chemicals at the site could pose a hazard, a qualified professional 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, capping with an impermeable cover, soil vapor extraction, and groundwater remediation and/or monitoring. Regnlatory agency oversight shall be obtained, as appropriate, from a local or State agency. An inventory of the interior areas of all on-site agricultural structures shall be conducted by an environmental professional prior to their demolition. If hazardous materials are identified as being stored in these areas, such materials shall be transported to and disposed of/recycled at an appropriate off-site facility. Monitoring by an environmental professional during the removal of floors/foundations shall be conducted to determine if hazardous materials spills are present or suspected to have occurred in these areas. After demolition, a report by the environmental professional shall be submitted to the City delineating whether hazardous materials appeared to be present below the floors or foundations. If hazardous materials are present, 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. SIGNIFICANT EFFECT Impact 4.9-2: Landffil Hazards. Use of the old landfill as a park on Lot 14 could result in exposure of the public to contaminants that may result in increased health risks. This would be considered a potentially significant impact. Vineyard Avenue Corridor Specific Plan Draft EIR -26- Findings
