  1. Leech Lake Emissions Inventory Brandy Toft Air Quality Specialist Leech Lake Band of Ojibwe

  2. Getting the Feet Wet in EI • Grant work plan in 2001 • Started on EI in Spring 2002 • Gathering data, exploring categories • Windshield surveys • Internet searches (EPA, State sites) • Did a GIS map for a visual aid • Realized it was a HUGE task and one that needed more time and staff

  3. The Help of TEISS • Introduced to TEISS in Fall 2002 • Training in Spring 2004 at FDL Rez • Great Tool !!! • Simplifies EI • Helps investigate emission sources and data needed for EI (calculators) • Create maps, graphs, tables, reports

  4. First Round DONE!!! • Submitted 2002 EI to ITEP for QA/QC • Make changes if needed • Will have ITEP submit Leech Lake’s EI to the NEI ~~~~~~~~~~IT’S NOT DONE~~~~~~~~~ • Keep eyes open • Prepare for EI update

  5. Leech Lake Emission SourcesPoint Sources • Title V’s within 100 miles • Paper mills, Pulpwood, OSB facilities (7) • EGUs (3) • Waste Incinerators (1-2) • Natural Gas Compressor Station (1) • Food Processing plants (1) • Large Aggregate facilities (2-3) • Large Boilers at Schools, Hospitals (4-5) • Taconite Mine and Processing facility (1)

  6. More Emission Sources • Area sources • Gas Stations • Backyard burning • Prescribed burning • Residential fuel heating • Mobile • On-road/Non-road • Assistance from LADCO

  7. Plume over Necktie

  8. Title VPotlatch OSB Plant

  9. Title VPotlatch Lumbermill

  10. Smaller FacilitiesCass Lake Forest Products

  11. Gas Stations 225+ = 5,980,600 gallons

  12. Backyard Burning2,462 tons per year

  13. Prescribed Burning3780 acres

  14. Residential Fuel Heating92,000 gallons per year

  15. Mobile Sources3 major roadways and tourism

  16. Mobile SourcesNonroad - tourism

  17. Paved/Unpaved RoadsChoose not to do

  18. Other Non Area SourcesNot Doing • Auto Body • Waste Treatment • Landfills • Gravel/Crush Rock • Portable Asphalt Plants

  19. PM 2.5 Density Plot

  20. PM 10 Density Plot

  21. VOC Density Plot

  22. The End • It is a complex project • Allow enough TIME • You set the scale/area for the EI • Grab data as it is presented to you, you will never know when it may prove to be useful • TEISS makes it a more attainable task • Tribes can accomplish their own EI • Encourage all to do an EI for your Rez
