This report summarizes the meteorological and air quality data that have been collected during the fourth quarter and the whole year of monitoring (September 12, 1981 to December 11, 1981 and December 12, 1980 to December 11, 1981), at the proposed WyCoalGas coal gasification project site near Douglas, Wyoming. Details concerning monitor operation, siting, and data collection are provided in earlier WyCoalGas, Inc., submittals to the Wyoming Department of Environmental Quality (DEQ) (November 17, 1980, and February 10, 1981). Quarterly precision and accuracy results are reported, as well as brief discussions of periods of maximum concentrations for each pollutant. Fourth quarter audit results were prepared from a performance audit conducted on December 1-3, 1981 (Woodward-Clyde Consultants March 1982). Measurements of wind speed and direction have been processed and summarized to provide a joint frequency distribution for the two sensor levels. Temperature data that have been tabulated and summarized, are presented in Appendix A-2.0. Visibility data have been summarized to provide a cumulative frequency distribution and are presented in Appendix A-3.0. Also provided are brief discussions of the ambient visibility. Total Suspended Particulate matter data from Station 2 (Project Monitor Site), have been tabulated for the period from September 16, 1981 to December 12, 1981 and are presented in SAROAD daily format in Appendix A-4.0. The results of the analyses of particulate matter samples for ambient lead concentrations are also presented in SAROAD daily format in Appendix A-4.0. Hourly data for the following parameters are presented in Appendix A-5.0: nitrogen dioxide (NO/sub 2/), sulfur dioxide (SO/sub 2/), ozone (O/sub 3/), visibility (B-scat), wind speed and direction (lower level (33 feet) and upper level (131 feet)), standard deviation of horizontal wind direction (lower level (33 feet) and upper level (131 feet)), temperature (33 feet), and pressure.
