  1. Air Quality Regulations – What’s New? (for Ethanol Plants) Shelley Schneider Air Quality Division Administrator

  2. Presentation Overview • National Ambient Air Quality Standards Revisions • Implications • Greenhouse Gas Regulation • Mandatory Reporting Rule • PSD and Title V Tailoring Rule • Opportunities for More Information

  3. Ambient Air Quality Standards

  4. Ambient Air Quality Standards Implications for Nebraska Ethanol Plants • NO2 • Sources model when permitting • April 2010 Steve Page memo • SO2 • Monitoring in Douglas County indicates non-compliance • Non-compliance = non-attainment • Douglas County only (at this time)

  5. Ambient Air Quality Standards • SO2 • EPA to require modeling for designation process • Nonattainment = monitored OR modeled violations • Attainment = modeled AND modeled evidence of no violations • Unclassifiable = all other areas, INITIALLY only

  6. Ambient Air Quality Standards • Proposed Revision to Ozone Standard • EPA will finalize by August 31st • Proposed PM Standards • EPA plans to propose in February 2011 • Finalize in October 2011 • Secondary NO2 and SO2 standards • Looked at together in separate rulemaking • Modeling compliance with NAAQS expected

  7. Ambient Air Quality Standards Implications for Nebraska • Ozone proposal • Monitoring in Omaha area indicates potential issues • NDEQ working with IDNR on plan • Voluntary measures if appropriate • Non-attainment plan if appropriate • Community Based Planning approach

  9. GHG Mandatory Reporting Rule • EPA implemented • Report electronically to EPA • 25,000 metric tons actual emissions CO2equiv or more must report • Begin reporting for CY 2010 • Deadline March 31, 2011 • No 3rd Party verification required • Monitoring plan in place by April 1, 2010

  10. GHG Mandatory Reporting Rule • Ethanol Facilities • Covered ONLY through combustion emissions • ≥ 25,000 metric tons CO2equiv actual emissions • All combustion units • Aggregate units • No exemptions for space heaters or insignificant units (except emergency equip) • Fermentation emissions don’t count (for now)

  11. GHG Tailoring Rule • “Tailors” PSD & Title V program for GHGs • Finalized May 2010 • Without Tailoring Rule, 250 and 100 tpy threshold apply • Nebraska has ~ 100 Title V sources subject to current program

  12. GHG Tailoring Rule • Does NOT mirror Reporting Rule • Short tons, not metric • Biogenic sources (ex. fermentation) count toward applicability • Phases in program • Expressed as CO2equiv

  15. GHG Tailoring Rule Implications for Nebraska • Rulemaking necessary to appropriately manage program • EPA requiring a letter outlining state’s plans by August 2nd • If rule isn’t adopted, EPA will be responsible for that piece of program • If rule is adopted, NDEQ and the appropriate local programs would be responsible • NDEQ plans to move forward with rulemaking in Fall 2010 • Program will mirror federal program

  16. GHG Tailoring Rule • Implications for Nebraska • Preliminary estimates • All /most ethanol plants will likely be major • Due to fermentation emissions • Actual emissions • ~ 30 to 50 minor sources may be ‘major’ for GHG emissions • Due to fuel combustion • Based on PTE • Increase Class I sources 30 to 50%

  17. GHG Tailoring Rule From Iowa DNR 2009 Emission Inventory Report for 2008

  18. GHG Tailoring Rule • Iowa Data on Actual Emissions • Fermentation only (need to include fuel too) • 121 MM gal plant • 0.33 MMt CO2equiv (396,000 tons CO2equiv ) • 110 MM gal plant • 0.30 MMt CO2equiv (360,000 tons CO2equiv ) • 77 MM gal plant • 0.21 MMt CO2equiv (252,000 tons CO2equiv )

  19. Opportunity for More Information • Air Waves E-Newsletter • Contact Tracy Thompson 402-471-4272 • Tracy.thompson@nebraska.gov • Air Program Updates • August 3rd in Grand Island • August 4th in Scottsbluff • August 10th in Norfolk • August 18th in Lincoln

  20. Air Program Updates • Topics to be Covered • Engines (everything you need to know!) • Air Regulations Update • Permitting – New Permit Review Policy, Greenhouse Gas Tailoring Rule, Modeling • Compliance – NAAQS, Chapter 34, Stack Testing • Air Toxics & NSPS Updates • The Air DVD – Your Guide to the Nebraska Air Quality Regulations

  21. Air Program Updates • Reminders and Changes • Register through NDEQ website • $10 registration fee • Payable 2 weeks in advance (preferred) • At the door • Cash or check only • Morning snacks, beverages, and lunch provided • Vegetarian meals can be provided • CDs with workshop materials
