4.0 Sampling Locations and Frequencies <br /> Four representative sites within the landfill fenceline will be sampled in this study. See <br /> Appendix B for a figure showing the asbestos sampler locations. <br /> Consistent with generally accepted practice for ambient air monitoring site selection, the sampler <br /> will be placed at a location that meets the following requirements to the maximum extent <br /> possible: <br /> The terrain will be level and will have no major obstructions (vegetation or other <br /> ' J ( g <br /> physical obstructions). <br /> •- The sampler inlet will be at a breathing level of approximately 2 meters above ground <br /> level and will face vertically downward. <br /> A duplicate set of integrated air sampling equipment will be co-located at one of the sites <br /> P g <br /> downwind of the active work areas. The duplicate sampling equipment will be located within 2 <br /> to 4 meters of the co-located equipment. <br /> Upon completion of the sampling event and sample analysis, Shaw will tabulate the field data <br /> and prepare a report to be submitted to the local enforcement agency (LEA). The report will <br /> include the field data and laboratory analytical data used to determine the asbestos baseline level <br /> and the sampling results. <br /> r <br /> PW Ald sdoc <br /> 9.6.05 4-] <br />
