<br />No Cement Kiln Dust loading, hauling, or disposal. <br />Normal wind ~;onditions, 3 to 11 MPH throughout the day. <br />No waterwagon due to the continuing wet conditions on roads and quarry. <br />Stack Opacity was within 'the normal or typical range all day, about 6 to 9°b. <br />Saturday, November 21 <br />Warm, Dry, Windy Day. <br />Watenvagon gun from 9:00 am to 2:30 pm watering plant roads. <br />No Cement Kiln Dust loading, hauling, or disposal. <br />Wind conditions were gusty and strong during several periods of the day. There <br />were more than 8 hours of the day when wind gusts were 15 to 40+ <br />MPH. The quarry was shut down. <br />Stack Opacit~~ was normal during the entire day. <br />Sunday, November 22 <br />Warm, Dry Windy Day. <br />Waterwagon run from 8:00 am to 4:00 pm watering plant roads. <br />Wind conditions were gusty and strong from roughly 10:20 in the morning <br />through midnight. The quarry was shut down. <br />No Cement Kiln Dust loading, hauling, or disposal. <br />Stack Opacity-was normal during the entire day <br />Conclusions: <br />First, because I was out of the area for the entire time, I do not have any first <br />hand knovvledge of weather or plant operating conditions. <br />There wa:: a high stack opacity for a period of time on 11119 that relates to <br />the complaint period. The precise mechanism of the high opacity is not <br />known although it corresponds with the routine startup of a process fan. <br />The windy conditions on 11/21 8 22 could have caused some dust in the <br />plant and quarry in addition to areas surrounding Southdown's property. <br />Plant employees took the prescribed actions in dealing-with Thursday's <br />opacity condition as well as the Saturday and Sunday high wind situation. <br />The quarry did not operate, no CKD was handled, and the waterwagon was <br />called in. <br />Ms. Mary Lou Dobbs views the plant from the east side looking west. She <br />indicated ':hat there wt;re problems throughout the time in question. One note <br />is that an~~ opacity appears to be significantly worse if viewed with the sun to <br />the side or behind. Due to the time of year, with the sun low and to the south, <br />most of the daylight hours will not provide an accurate means of evaluating <br />opacity when viewing east to west. In fact any condition will be exaggerated <br />due to the lighting conditions... <br />p' //-7 <br />
