1 TSD-phg/12-1-97/AGAIRQU.PPT Improving Agricultural PM 10 Emission Estimates in California Dale Shimp California Air Resources Board December 1, 1997 dshimp@arb.ca.gov 916-324-7156

2 TSD-phg/12-1-97/AGAIRQU.PPT Emission Inventory n Comprehensive Estimates of Emissions from Air Pollution Sources n Point, Area, and Mobile Sources n Based on Typical Local Conditions n ARB & District Cooperative Effort n Continual Improvements

3 TSD-phg/12-1-97/AGAIRQU.PPT Estimation of Emissions n Emission Factor (EF) –Emissions per unit of activity (i.e., lbs/PM 10 per acre tilled) n Activity Data (Process Rate, PR) –Vehicle Miles Traveled, Acre-Passes n Emissions –Emissions = EF x PR

4 TSD-phg/12-1-97/AGAIRQU.PPT Particulate Matter Is... n Sand and Soil – Geologic material, dust, dirt n Soot –Combustion products, wood smoke, diesel exhaust n Secondary Particles –Formed via reactions in atmosphere of gaseous pollutants

5 TSD-phg/12-1-97/AGAIRQU.PPT Particulate Categories n TSP - Total Suspended Particulate –PM 30 : particles 30 microns of less in size; mainly composed of geologic material n PM 10 - particles 10 microns or less –Can be dominated by geologic dust particles or secondary particles n PM 2.5 - particles 2.5 microns or less –Typically combustion products & secondary PM

9 TSD-phg/12-1-97/AGAIRQU.PPT Land Preparation n Acreage Data from California Department of Food and Agriculture n Cultivational Practices from Farmers n Emission Factors from AP-42 (U.S. EPA) n NRCS Soil Silt Data

10 TSD-phg/12-1-97/AGAIRQU.PPT Harvesting n Acreage Data from California Department of Food and Agriculture n Cultivational Practices from Farmers n Emission Factors from UC Davis

11 TSD-phg/12-1-97/AGAIRQU.PPT Wind Blown Dust n Land Use Data from Department of Water Resources n Soils Data from Natural Resources Conservation Service n Incorporated Crop Canopy and Irrigation Effects n ARB Estimation Methodology Adapted from USDA Soil Erosion Equation

12 TSD-phg/12-1-97/AGAIRQU.PPT Agricultural PM 10 and the Overall PM 10 Inventory n Annual Emissions Deceptive n Farm Operations High in the Fall n Windblown Dust High in the Spring

13 TSD-phg/12-1-97/AGAIRQU.PPT Monthly SJV PM 10

14 TSD-phg/12-1-97/AGAIRQU.PPT Planned Inventory Improvements n Crop and Equipment Specific Emission Factors n Additional Harvest Emissions n Livestock Emissions (Ammonia & Dust) n Further Use of GIS Based Estimates

15 TSD-phg/12-1-97/AGAIRQU.PPT PM 10 Emission Changes TSD-phg/5-27-97

16 TSD-phg/12-1-97/AGAIRQU.PPT Crop Calendar for Cotton

17 TSD-phg/12-1-97/AGAIRQU.PPT Seasonal Activity Profile

18 TSD-phg/12-1-97/AGAIRQU.PPT Agricultural PM 10 Meetings n Work with Farm Industry Representatives n Identify Crops to be Updated n Meet With Growers of Identified Crops n Complete Crop Calendars for All Major SJV Crops

19 TSD-phg/12-1-97/AGAIRQU.PPT PM 10 Emissions Sources for SJV
