This report summarizes the results of the preliminary hydrocarbon inventory and present the detailed plan for source testing. The preliminary inventory which account for 6,000 point sources plus area source indicates that average daily emission in the South Coast Air Basin and Ventura County is 710 tons per day. Petroleum operations (production, refining and marketing) account for nearly half of these emissions while solvent users account for over 40%. Based on this preliminary inventory a list of candidate sources to be tested is presented. Testing began in November 1976 and will continue through April 1977. Emission samples will be collected in borosilicate jars, Tedlar bags and tubes containing activated charcoal. Samples will be analyzed using GC/MS techniques. The charcoal samples will be extracted using carbon disulfite before analysis. Plans for control of data quality and for determination of experimental error are also discussed.
