US Ethanol Production
● As of January 2007 Approximately 5.6 billion gallons ethanol
being produced annually in US. Up 300% since Year 2000 In 2006, approximately 17% of corn
produced went to ethanol productionSource: Renewable Fuels Association, Ethanol Industry Outlook 2007, Building New Horizons
Ethanol industry experiencing significant growth

Typical Air Emission Control Equipment:● Dryer (DDGS) Emissions: Thermal Oxidizer● Denatured Ethanol Loadout: Flare● Biomethanator: Flare● Fermentation: High Efficiency Packed Tower Scrubber● Fugitive VOCs: Leak Detection and Repair● Road Dust: Regular Plant Street Sweeping● Process Dust: Baghouses● Tanks: Internal Floating Roofs (with double wiper seals)● Process Vents: Vented to Thermal Oxidizer● Diesel Emergency Water Pump: Lean Burn Technology
Industry “Standards”

250 tpy Rule Summary
Air Permitting as “minor” source● < 100 tons/year (old rule)● < 250 tons/year (new rule)● States required to adopt 250 tpy rule● NRDC filed lawsuit on July 2, 2007● RFA team is preparing “Amicus Brief”● Public health, safety and environment
remain protected with new rule

250 tpy rule details
● Ethanol plants – no longer chemical process plants for PSD purposes.
● 250 rule applies – new and modified plants.● Fugitives (road dust, pumps, valves, flanges
& perhaps cooling towers) are no longer included in the PSD emission inventory for applicability. LDAR is still required.
● Existing plants may expand to 249 tons & remain minor. Leaves additional 249 tons.
● All plants will still need TOs and Scrubbers.
