6 f Equipment Installationand Calibration <br />Shaw personnel will set up the samplers at each of the identified sampling locations. Once the <br />equipment is functioning properly, an air intake hose will be attached to each cassette base. The <br />cassette cap will be removed and the cassette will be positioned downward, perpendicular to the <br />wind. The power will be turned on and sampler pump will be switched on. The sampler will be <br />Ieak-checked before the start of the sampling event. A pre-test calibration with a flow meter will <br />be performed and the data on flow rate and pump specifications will be recorded. Shaw <br />personnel will monitor the samplers for fluctuations in the flow rate by means of rotameter and <br />visual inspections. At the end of the 8 -hour sampling period, the sample pumps will be shut <br />down and a post-test calibration will be performed. The filter cassettes will be removed from the <br />sampler and placed in individual sealed plastic bags. <br />Shaw personnel will attach a COC and send the samples to ATEM. ATEM is an accredited <br />analytical laboratory for TEM analysis. <br />Shaw personnel will also gather the relevant concurrent average meteorological data (wind speed <br />and wind direction) from the landfill MET station. <br />10 Asbestos Samr ,,r, <br />This project will strive to meet the criteria for representativeness as promulgated by TEM <br />Method 7402 for asbestos sampling systems. These criteria are as follows: <br />• An 8 -hour representative data sample will be obtained at each of the four sites <br />indicated in this protocol. <br />• Equipment malfunctions will be minimized by equipment checks and inspections prior <br />to sampling by Shaw personnel. Equipment malfunctions are the greatest challenges to <br />meeting the project's representativeness goals. <br />• In order to acquire valid data, the sampler will be calibrated before and after the <br />sampling event. <br />• Each Sampler will be configured and duly calibrated prior to sampling. Shaw <br />personnel will follow the procedures in the sampler operation manual to set up and <br />initiate sampling. <br />• A pre-test calibration with a flow meter will be performed and the data on flow rate <br />and pump specifications will be recorded. <br />• During the sampling event, Shaw personnel will monitor the samplers for fluctuations <br />in the flow rate by means of rotameter and visual inspections. <br />6-1 <br />
