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):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 PM 10 PM 2.5 OZONE NOx SOx Carbon Monoxide Lead (Pb) Volatile Organic Compounds Carbon Dioxide* Mercury (Hg)

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.
