Presentation Transcript

  1. Ag Contribution to VOC Emission Inventory (2002) • Total Annual VOC Emissions: 413.0 t/d • Ag contribution (21.2%): 87.4 t/d • Total Mobile Sources (86.7%): 357.9 t/d

  2. Environmental Quality Incentives Program (EQIP)

  3. Agriculture Ozone Precursors • Oxides of Nitrogen (NOx): tons/year Example Irrigation Engine (1986 model, 350 h.p., runs 2600 hrs): NOx produced – 7.2 t/yr Irrigation Engine (2003 Tier II model, 350 h.p., 2600 hrs): NOx produced – 3.1 t/yr • Volatile Organic Compounds (VOCs): Example Dairy gives off between 5 – 13 lb/head/yr @ 13 lb/hd/yr, 1500 hd = 10 tons

  4. AIR QUALITY PM10 PM2.5 OZONE Volatile Organic Compounds NOx Mercury (Hg) Carbon Monoxide SOx Lead (Pb) Carbon Dioxide*

  5. AGENDA • Introduction • Air Quality Parameters • PM-10 • Ozone • Conclusions

  6. CONCLUSIONS • Agriculture can be a significant source of air pollution. • Monitoring sophistication and research is needed to pinpoint speciation and amount of PM-10 and ozone. • Agriculture is being proactive in dealing with it’s share of the air pollution problem. • Agriculture cannot pass on the cost of air pollution controls to consumers.
