  2. Clean Air Sustainable Agriculture Sound Land Management Clean Water Key elements: Scientific assessment Outreach and education Implementation/compliance

  3. Ozone and PM designations and implementation • Fugitive dust • Conservation management practices • Permitting • Title V • New source review • Offsets • Pesticide application

  4. Agricultural equipment • Title II rule amendment - pumps • Fire • Prescribed fire, wildfire • BlueSky/Rains • AFO/CAFO • Particulate Matter (PM) • Hydrogen Sulfide (H2S) • Ammonia (NH3) • Odor

  5. Attainment and Nonattainment Areas in the U.S. 8-Hour Ozone Standard Attainment or Unclassifiable Areas (2668 counties) Nonattainment Areas (432 entire counties) Nonattainment Areas (42 partial counties)

  6. State Recommendations for Fine Particles National Ambient Air Quality Standards Nonattainment (full county): 142 Nonattainment (partial county): 9

  7. EPA Response to State Recommendations on PM2.5 Designations – June 29, 2004

  8. Counties Designated Nonattainment for PM10

  9. Title V could apply to farms, resulting in: • Paperwork burden • Unnecessary public scrutiny • Little if any benefit for the additional burden • Continuous compliance assurance monitoring and reporting • Biosecurity impacts

  10. Change in farming practices could trigger NSR (NSR being the bigger issue), resulting in: • Requirements to obtain offsets for emissions increases • Applying lowest achievable emissions rate to new equipment or new practices • Paperwork burden

  11. VOC • Toxics • Methyl Bromide • Spray Drift

  12. Emissions from farm equipment • PM and NOx • Irrigation pumps • Stationary source v. mobile – State regulated • Mobile source – national rules apply • Title II • Alternatives • Cleaner burning diesel engines • Natural gas engines • Electric engines

  13. Pollutants: PM Regional haze Episodic ozone Air toxics Impacts: Water runoff to streams Air quality Visibility Smoke

  14. EPA’s Fire Policies • EPA acknowledges the use of fire as an efficient and economical land management tool in maintaining the health of fire-tolerant and fire-dependent plant and animal ecosystems • Maintain species diversity • Enhance agricultural production • Eliminate the threat of disease • Reduce catastrophic wildfires • PM-10 Natural Events Policy (1996) • Interim Air Quality Policy on Wildland and Prescribed Fires (1998) • Agricultural Burning Policy (on hold)

  15. Blue Sky RAINS • BlueSky/RAINS (BSR) is an interactive web-based tool that predicts smoke concentrations on a variety of sensitive receptors • BSR couples the latest available science in fire behavior and smoke dispersion from the BlueSky framework developed by the USFS with the Geographical Information System (GIS) and sequential database technology of the Rapid Access Information System (RAINS) developed by EPA R10

  16. Blue Sky RAINS (cont.) • EPA Region 10 and the USDA Forest Service have successfully operated BSR in the Pacific Northwestern US since March 2003 • Leavitt Initiative - expand the BSR nationwide within the next 1 to 2 years • Currently, a beta version of the BSR that covers all or part of 11 western states is being tested

  17. NAS Commissioned: • EPA and USDA asked NAS to perform CAFO air emissions study • NAS Study Conclusions: • No reliable emissions factors for AFO exist • Additional data needed to develop estimating methodologies • Current methods for estimating emissions not appropriate • Use process-based approach

  18. Industry: - Pay a civil penalty (per facility) - Contribute to nationwide emissions monitoring program ($2,500) - Make facilities available for monitoring - At conclusion of study, apply emissions-estimating methodologies to identify applicable CAA, CERCLA and EPCRA requirements - Certify compliance with CAA permitting and CERCLA and EPCRA notification provisions - EPA grants limited covenant not to sue
