Each sample was collected from 9 feet above the ground in a 10-liter <br /> Tedlar bag following the protocol specified in the Guidelines. While <br /> the ambient air samples were being collected, wind speed and direction <br /> were continuously measured and recorded. Meteorological monitoring <br /> data is presented in Appendix H. The 24-hour average wind speed did <br /> not exceed the 10 mph criterium in the Guidelines or the 15 mph <br /> criterium proposed in the workplan. Immediately after each 24-hour <br /> period, the samples were removed from the samplers. Within 72 hours <br /> after collection, each sample was analyzed by Central Coast for the <br /> 10 VOCs specified in the Guidelines. Analytical procedures are <br /> included in Appendix D. <br /> 3.4 RESULTS <br /> Table 5 summarizes the analytical results. Complete analytical <br /> reports are included in Appendix E. Appendix F contains field infor- <br /> mation including EMCON's sample identification number, and date and <br /> time of sample collection. Appendix G contains chain-of-custody <br /> records for the samples. <br /> Review of the wind data for the 72-hour period over which the samples <br /> were collected indicated the following: <br /> • From 1200 hours, February 17, 1988 through 1200 hours, <br /> February 18, 1988, the average wind speed was 9.4 mph. <br /> The predominant wind direction was from the 90-degree <br /> quadrant bounded by the south-southwest and west- <br /> northwest axes. <br /> • From 1200 hours, March 2, 1988 through 1200 hours, <br /> March 3, 1988, the average wind speed was 4 mph. The <br /> predominant wind direction was from the 90-degree quad- <br /> rant bounded by the southeast and southwest axes. <br /> PJ9 9390304.00D 3-2 Rev. 0 09/20/88 <br />
