VZ1 INC <br /> Task 3-Soil Aeration and Landfarming O eration <br /> Sod aeration and landfarming will be utilized to remediate the volatile and heavy fraction <br /> i <br /> hydrocarbon impacted soil <br /> This Remedial Action Plan assumes that volatile hydrocarbon and chlorinated <br /> hydrocarbon compound concentrations will be low enough (under 100 ppm) to meet all <br /> permitting criteria for VAD requirements for on-site aeration of the volatile fraction <br /> Heavy fraction hydrocarbon stockpiled sod will be remediated by landfarming <br /> During this period the stockpiled soil will be inspected on a weekly schedule to insure <br /> stability and integrity of the pads The stockpiled sod will be watered to keep moisture <br /> content at optimum levels Tillage of the sod will be made with a tractor or handheld 10" <br /> deep disc which will aerate the sod and allow maximum bacterial action Horse or <br /> chicken manure will be applied as appropriate to increase nitrate levels in the sod and <br /> . enhance the bacterial action <br /> Periodic samples will be taken to monitor the progress of bacterial degradation of the <br /> hydrocarbons Target goals for reduction of TPH-G are set at non-detection levels <br /> Target goals for reduction of TPH-D are set at 100 parts per million <br /> Task 4-Final Closure Report <br /> The final report will summarize all technical aspects of the operation and be certified by <br /> a California State Certified Engineering Geologist and submitted to SJCLHD for approval <br /> IV.
