8/3/2010 I called Bill and questioned the 7/30/2010 12:00 pm one hour opacity reading. He called me back on 8/3/10 to inform me the the next 6 minute average reading was marked bad (opacity was 94.3%). It did not show up on the 6 minute results but it did get averaged in the one hour average. The oxygen readings read all zeros also which tripped the ESP and the kiln was taken down. CINDY GARZA
