4.0 Sampling Frequency and Locations <br /> Shaw will perform one asbestos monitoring test during the months of March and October for <br /> each year. The asbestos level will be continuously monitored by collecting 8-hour low-volume <br /> asbestos air samples on the one chosen day. The sampling day will be chosen in coordination <br /> with Allied to coincide with the landfill's asbestos disposal-related activities. Four <br /> representative sites within the landfill fenceline will be sampled in this study. <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 /> 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 /> 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 />
