Jones <br /> Woodbridge Partners Inc. <br /> 639 East Lockeford St. <br /> Lodi, CA 95240 <br /> CLOSURE PLAN FOR POND 1,VICTOR FINE FOODS FACILITY, SAN JOAQUIN <br /> COUNTY(513392043001) <br /> Central Valley Regional Water Control Board staff(staff)has reviewed The Closure Plan for Pond No. <br /> 1 (plan) submitted on 12 March 2004. The plan proposes to close Pond 1 by removing all liquids by <br /> evaporation,removing and drying any remaining solids, discharging dry solids to an approved landfill, <br /> and removing liner materials for salvage or disposal. Drilling a single borehole in the pond center with <br /> core samples collected at 5 feet intervals will test condition of the soil beneath the pond. The plan does <br /> not specify the analytes to be tested. The pond excavation will be reclaimed by filling to grade with <br /> moisture conditioned, compacted, on site soils. Similar soils used in the closure of Pond 2 achieved a <br /> permeability of 2.5 X 10-3 cm/sec. A vegetation layer of stockpiled surface soil will be placed and the <br /> area of the pond will be graded to shed storm water. Staff has the following comments concerning the <br /> proposed plan: <br /> 1. The plan to remove all liquids, solids and liner materials complies with requirements of Title <br /> 27. Staff concurs with this part of the plan. <br /> 2. The footprint of Pond 1 is not large and a single confirmation borehole with core samples <br /> collected every 5 feet to the water table is adequate confirmation sampling. The core sample <br /> must be analyzed with DI WET extraction for TDS, chloride and sodium. The results should <br /> be compared with background soils to determine if they have been contaminated. The <br /> background samples collected for the Pond 2 investigation(GVP2 NP and GVP2 SP) and <br /> reported in the 6 June 2000 Pond 2 Soil Sampling Results from Boring DBI'report are near <br /> enough to be representative of Pond 1 background and may be used. <br /> 3. If soils beneath Pond 1 are not contaminated relative to background soils closure of Pond 1 may <br /> proceed as proposed. If significant contamination is detected that is a threat to water quality <br /> either all contaminated soils that is a threat must be removed or Pond 1 must be closed as a <br /> landfill. Title 27 Section 21400(b)(1) states in part '...If, after reasonable attempts to remove <br /> such contaminated materials, the discharger demonstrates that removal of all remaining <br /> contamination is infeasible, the surface impoundment shall be closed as a landfill or land <br /> treatment unit, as appropriate,pursuant to &(b)(2).
