Monitoring must be performed by <br /> individuals trained in the use and care of the monitoring equipment. A record of the <br /> instrument readings and calibration Wbrmation froill be kept in the field log book. <br /> All air monitoring devices will be calibrated daily and the calibration frvilf be checked- <br /> This concentration and the gas used will be recorded in the field log book. All readings <br /> wiil be recorded as ppm equivalent. Action levels are specified in ppm equivalents. <br /> if field personnel detect hydrocarbon odors, measurements shall be made about 6 <br /> inches from the soil,at both upwind and downwind positions. If the total hydrocarbon <br /> concentmttom at these locations exceed ff.e resplrator use action levels, <br /> measurements must then be made in the brea'lhing zone of;he individual(s) avortdng <br /> closest to the soil. Decisions regarding respiratory proteciion should be made using <br /> vapor concentrations in the breathing zone. <br /> 6J0 DEOC+NfAAWMTK)N <br /> 5-I PHUSO� <br />
