Figure B-1 indicates maximum one-hour concentrations for the years <br /> 1962-1974. Figure B-2 indicates the number of hours the national <br /> standard has been exceeded. <br /> The other pollutant which has been identified as a problem in the <br /> AQMA process in the San Joaquin-Stanislaus area is Total Suspended <br /> Particulates. Figure B-3 shows the maximum 24-hour Total Suspended <br /> Particulate concentrations measured each year at monitoring stations <br /> in the area. Total Suspended Particulates are also required to be <br /> below allowable limits for the Annual Geometric Mean. Figure B-4 <br /> illustrates the Annual Geometric Mean for the air monitoring stations <br /> listed in Table 2. The Annual Geometric Mean is one way of averaging <br /> the Total Suspended Particulates. Note that the data are consistent- <br /> ly above the federal standard, as opposed to the 24-hour data. This <br /> indicates that our long term air quality concentrations for Total <br /> Suspended Particulates are consistently higher than levels that are <br /> considered adequate. <br /> In an effort to define the sources of photochemical oxident and <br /> particulate pollutants preliminary studies have been made to deter- <br /> mine the relative quantity of pollutants emitted each day by general <br /> sources based upon an average daily figure of pollutants emitted <br /> into the air. These preliminary results are shown on Table 2. <br />
