AND HAMMERMILLS
Standard AP-42 emission factors
Controlled by fabric filters
Potential PSD issues if they are co-located with an
existing elevator from whom they will get a majority of
their corn.

FERMENTATION AND DISTILLATION
Usually controlled by a scrubber, and sometimes
further vented to the thermal oxidizer on the DDGS
dryers.
CO2 emissions from fermenters may be sold to a third
party

DDGS DRYER
Controlled by thermal oxidizers to stay minor for PSD
Variable VOC emission factors
0.013 lb/1000 gal to 0.17 lb/1000 gal
Highly variable HAP emissions
Acetaldehyde or methanol highest

STORAGE TANK & ETHANOL LOADOUT
Tank emissions using EPA’s TANK program
Loadout - follow AP-42
If non-dedicated tanks or trucks allowed, controlled
by flares in all but smallest plants
Rail loadout in dedicated tank cars may be controlled
by flares, especially if the plant is over 65 mmgal/yr
