DAQ Internal Comments:
2021 stack test for PM, HCL, Pb, Cd, and HG used to update factors, resulted in emissions increases/decreases.
Change to slightly more conservative emissions estimation methodology resulted in emissions increases for other
pollutants. Natural gas usage decreased which resulted in decrease in hexane, ammonia, and formaldehyde emissions
