4.0 Sampling Frequency and Locations <br /> Shaw will perti)rrr. one asbestos monitoring test during the months of March and October for <br /> each year. The asbestos I-evel will be continuously nj()rijored by collecting 8-hour low-volurne <br /> asbestos air samples on the one chosen day. The sampling day will be chosen in coordination <br /> with Allied to coincide with the land'fill's asbestos disposall-related activities. Four <br /> representative sites within the landfill fenceline will be sampled in this study. <br /> Consistent with generally accepte-d practice for ambient air monitoring site selection, the sampler <br /> will be placed it 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*on or other <br /> physical obstructions'l. <br /> • 2 g <br /> The sampler inlet will be at a breathing level ol'ap <br /> pmamtely meters above roundroxi <br /> level and will face vertically downward. <br /> A duplicate set of integrated air sarnp[ing equipment will be co-located at one of the sites <br /> downwind cit'the: active work areas. The duplicate samplin(T equipment wit', be loo-ated within 2 <br /> to 4 meters cif the co-locaied 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 etifiorcernent agency (I.E.A). The report will <br /> include the field data and laboratory analytical data used to determine the asbestos baseline level <br /> and the sarnpling results. <br />
