-8- <br /> 6. PRE-TEST PROCEDURES <br /> 6.1 Assemble the portable tank assembly and gas volume meter as shown in <br /> Figure 4. The minimum and maximum dimensions shown in Figure 4 shall <br /> be adhered to in all cases. Ensure that the ground strap is properly <br /> connected to an acceptable ground. <br /> Note: A one-time test to verify proper design of the tee connection at the gas <br /> volume meter shall be conducted. Disconnect the V/L adaptor from <br /> the nozzle. Insert the nozzle into the portable test tank so that there <br /> is no visible gap between the nozzle boot/portable test tank fill pipe <br /> interface. Dispense between four and one-half and five (4.5 - 5.0) <br /> gallons into the portable test tank. The tee connection design passes <br /> the test if the displacement on the gas volume meter is less than 0.01 <br /> cubic feet. The result of this test shall be kept with the test equipment. <br /> If the tee connection is altered or changed, the above test must be <br /> repeated to ensure proper design. <br /> 6.2 The gas volume meter shall be calibrated, within 180 days prior to conducting <br /> this procedure. In addition, calibration shall be conducted after any repairs <br /> or alterations (changes to the operation or configuration of the meter) to the <br /> meter. Calibrations, at a minimum, shall be conducted at flowrates of 30, 60, <br /> and 90 CFH (3.7, 7.5, and 11.2 gallons/minute) in accordance with one of the <br /> following: <br /> (a) ARB Air Monitoring Quality Assurance, Volume VI, Standard Operating <br /> Procedures for Stationary Source Emission Monitoring, January 1979, or <br /> (b) US EPA Quality Assurance Handbook for Air Pollution Measurement <br /> Systems, Volume III, Stationary Source Specific Methods, or <br /> (c) EPA Method 2A, Measurement of Gas Volume Through Pipes and Small <br /> Ducts (40 CFR Part 60, Appendix A), or <br /> (d) Appropriate calibration procedures in accordance with California <br /> Department of Food and Agriculture, Division of Measurement Standards <br /> and County Department of Weights and Measures (title 4, CCR, section <br /> 3.33). <br /> A copy of the most current calibration shall be kept with the meter. <br /> Healy Model 900 Nozzle V/L Test Procedure, Exhibit 5—Executive Orders VR-201-D and VR-202-D <br />
