No, dry mill ethanol plants (the most efficient and cost-effective flavor we have now) are considered minor sources up to 100 Million gallons/year. At 150+M gallons a year they are considered major sources. You have to get an air permit to build one of these plants even if you are ADM, Cargill, Fagan, Lurgi PSI, Delta-T, etc. etc.
What the democrats across the midwest have done is attach a PLA to every air emissions permit. It works well because you have to agree to all-union labor, which jacks the price of a 100M gallon/year plant from about 140M to about 165M. Then they get you your air permit, point you toward between $5M and $10M of taxpayer money for grants, and try to lure you with other perks like enterprise zones.
The mainstream media will *never* report the damage democrats and all of their associated payoffs cost taxpayers and the nation in general.
