Bread Baking Ovens

​​Bread baking ovens are any natural gas-fired ovens that bake dough containing yeast.  During the fermentation process of baking, the yeast releases VOC containing emissions, mostly ethanol.  When the bread is baked in an oven, the high temperature releases the alcohol from the bread resulting in emissions.

Who Needs a Permit?

  • Any baking operation that is based on the quantity of dough baked has the potential to emit greater than or equal to 2 lbs/day of VOCs.

  • Any natural gas oven rated 1 MMBTU/hr or higher.
