9 6.0 Equipment Installation and 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 casseLtc base. '111C <br />cassette cap will be removed and the cassette will be positioned downward, I)erT.)endicular to the <br />wind. The power will be turned on and sampler pump will be switched on. The sampler will be <br />leak -checked before the start of the sampling event. A pre-test calibration with a flov,, mem- will <br />be perfiornied and the data on flow rate and pump specifications will be recorded. Sha%A, <br />personnel will monitor the samplers for fluctuations in the flow rate by means of rotaineter and <br />visual inspections. At [tie end of the 8 -hour sampling period, the sample l)uTnps will be shut <br />down and -I post-test calibration will be performed. The filter cassettes will be removed from the <br />sampler and placed in individual scaled plastic bags. <br />Shaw , aw personnel will attach a COC arid send the samples to ATEM. ATI'M is an accredited <br />analytical laboratory for -TEM analysis. <br />Shaw personnel will also gather the relevant C(-)IICIIFI-Cnt average meteorological data (wind speed <br />and wind direction) from the landfill MET station. <br />WON <br />This pr 'ect will strive to meet (lie criteria for representativeness as promulgated by TI'M <br />QJ <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 slics <br />Indicated in this protocol. <br />• Equipment malfunctions will be nuinli-nized by eqUIPTI)MI, check,,; and )inspections prior <br />to sampling by Shaw personnel. Equipment malfunctions are the greatest challenges to <br />meeting the project's representativeness goals. <br />• III 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 LIJ) 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 <br />event, Shaw personnel will monitor <br />the samplers for fluctuations <br />III the flow <br />rate by tricans of rotameter <br />and visual inspections. <br />
