DAQ Internal Comments:
PM(TSP), PM10 and PM2.5 emission increment was due to Hours of Operation increase in Crushing and Screening
Plant and in Coloring Plant. CO,NOx, S02, Arsenic, Beryllium, Cadmium, Chromic acid, Cobalt, Lead, Mercury,
Nickle,Naphthalene, Benzene, Formaldehyde, Hexane, PAH and Selenium Compounds emission decrease was due to
decrease in annual throughput in OS 13 (Dryer with controls-Normal operation-COMBUSTION). VOC emission
increased due to increment of operating hours in OS 10 (Coolers).
