Regulatory Drivers

• State Implementation Plans
• 8-hour Ozone June 2007
• PM 2.5 late 2007
• Permitting
• Federal
• State

California SB 700

• State permitting of new and modified facilities
  (current)
• Create clearinghouse of control measures (Jan
  2005)
• Define large AFO (July 2005)
• BACM/BARCT implementation
• (Jan 2006)
• Permit existing facilities (July 2006)

Current Research

• Flux chambers
• Whole animal chambers
• LIDAR
• See handout

Research Needs

• Methods to estimate emissions (including all
  portions of AFO)
• Atmospheric chemistry and modeling (e.g. ammonia)
• Technology and practices to reduce emissions
