«mow <br /> MAY 2 8 1992 <br /> CONSTRUCTION OF THE ENVIRONNIENTAL HEALTH <br /> PERM r f ; C'ES <br /> SOILS RECYCLING FACILITY <br /> LODI, CA <br /> The facility will be located on the northeast corner of the <br /> intersection of Cluff Avenue and Turner Road as indicated on the <br /> enclosed drawing, "California Waste, Site Plan" . Within the <br /> designated three acre site, the necessary equipment, buildings <br /> and stockpile areas will be arranged in accordance with the <br /> enclosed sketch, "Soils Recycling Facility, General Layout" . <br /> Analyses to determine the current chemical condition of the site <br /> will be completed prior to initiating construction of the <br /> facility. <br /> Up to 3,000 tons of incoming contaminated soil will be stockpiled <br /> in a 12,000 square foot area with approximate dimensions of 60 ' <br /> by 200 ' . This entire area will have an 18" high earthen berm <br /> around the perimeter and will be lined with 40 mil high density <br /> polyethylene laid on top of compacted native soil . .All liner <br /> seams will be heat sealed. The liner will extend over the berm <br /> and will be properly secured at the outer edge of t , berm. A <br /> leachate collection and removal system consisting of perforated <br /> plastic piping immersed in a 6" layer of river rock will be <br /> installed immediately above the liner. To avoid damaging the <br /> liner or disturbing the leachate collection and removal system, a <br /> 6" layer of compacted soil will be maintained in this stockpile <br /> area. <br /> The stockpile area will be slightly sloped so that any leachate <br /> collected will flow into a sump. In the sump, a level switch <br /> activated pump will transfer the leachate into Baker storage <br /> tanks. From storage, the leachate will be used to supplement the <br /> moisture content of particularly dry incoming soils. <br /> To control dust and fugitive emissions, all soil will be kept <br /> slightly moist at all times, but not so moist as to result in <br /> leachate runoff. If necessary, heavy tarps which resist tearing <br /> and are not easily blown off will also be used. <br /> The thermal processing unit, which we refer to as the Soils <br /> Remediation Unit, is mounted on one 40 ' long semi-trailer. After <br /> the unit is positioned and leveled, the rear door and both side <br /> doors are opened. Soil is fed into the unit through one side door <br /> and the treated soil is discharged though the rear door. The <br /> control panel and the primary operator work area are accessed <br /> though the other side door. A color photo of a unit in operation <br /> is enclosed. <br /> After treatment, the recovered soil will be stockpiled in a 6,000 <br /> square foot area with approximate dimensions of 60 ' by 100' , The <br />
