PI Pit VC V.APPLICABLE STANDARDS/RISK DETERMINATION 9NA <br /> + Remediation system design diagrams showing how the <br /> system will be constructed in the field. <br /> + A remediation system operation and maintenance plan 32 <br /> that describes, at a minimum, how the system will be operated to <br /> ensure that it functions as designed without interruptions and a <br /> sampling program that wilt be used to monitor its effectiveness in <br /> achieving the desired goal. <br /> + The plan should describe the sampling program that will 29 <br /> be used to verify that treatment of the contaminated media has <br /> _ resulted in attainment of the proposed clean-up goals. <br /> + • The plan should include a schedule of implementation. 32 <br /> + The clean-up completion report is necessary to demonstrate that the Submit <br /> remediation was completed according to the application.Again,since in <br /> remediation is involved, the report is beyond the scope of a Phase I or II Future <br /> assessment. The following items should be included in the completion <br /> report <br /> + A final list of all site contaminants,along with the Submit <br /> remaining concentrations,and any deviations from the original in <br /> plan. Future <br /> + - A final list defining which media are contaminated and the Submit <br /> estimated vertical and areal extent of contamination to each in <br /> medium. Future <br /> + A final list and map defining all source areas,areas of Submit <br /> contamination or contaminant discharge areas. in <br /> Future <br /> Soil Contamination_ Remediation by Excavation Only. NA <br /> + One confirmation sample per 500 as measured at the NA <br /> base on the excavation OR two confirmatory samples,whichever <br /> method results in the collection of the most samples. <br /> + One composite sample from each wall of the excavation. NA <br /> In excavations of an irregular shape,one composite sample for <br /> every 100 lineal feet of waif. For excavations grater than 5000 ftz, <br /> preparation of a grid for randomization of sampling. <br /> + Explanation of the sampling method in the narrative as NA <br /> well as any modifications to 1 and 2 above used to better <br /> characterize the remedial efforts. <br /> + If contamination is to be left in place, an additional sample NA <br /> should be collected from the area of the worst contamination,as <br /> verified or with a field-sampling device. <br /> + Depth of samples collected NA <br /> + Provision of waste disposal manifests NA <br /> iZii0y3t Tiger VCtlP App!"ication _.�.�... .__,...
