  1. WOODSTOVE CHANGEOUT ON THE

  2. Johna Boulafentis & Tui Moliga Nez Perce Tribe Environmental Restoration and Waste Management Air Quality Program

  3. Hypothesis • Wood stove replacement will reduce indoor levels of PM and associated wood smoke chemical markers from domestic wood burning?

  4. Project Partners • EPA • University of Montana • Northwest Indian College, Nez Perce Tribe Distance Learning Centers • Institute for Tribal Environmental Professionals • Washington State University Extension Energy Program • Swinomish Tribe • Ni Mii Puu Health • Nez Perce Tribe Housing Authority • Nez Perce Tribe Forestry & Fire Division • Nez Perce Tribe Safety Program

  5. Study Overview • Recruit 16 households • Outreach and Education • Measure before and after changeout • Ambient air • Indoor air • Health of asthmatic child • Conduct sampling during winter months • Wood stove changeout

  6. Free EPA-Certified Woodstoves Available! • Participate in ERWM’s • Woodstove Study & Changeout • Qualifying Residences: • Use an old woodstove as the primary source of heat • Are a nonsmoking, tribal member home in Lapwai or Kamiah • Have a child between ages 6 and 17 with asthma or respiratory related illness • Participants Receive: • New, cleaner burning and more efficient woodstove • Improved indoor air quality in home • To participate or for more information, contact • Johna Boulafentis at 843-9381 x23671

  7. Outreach and Education • Office • Media • KLEW T.V. • Articles/Informational Notices • Letters & mass email • Posters • Field • Presentations & Air Quality Booth

  8. Ambient Monitoring • Utilize existing network in Kamiah and Lapwai • PM2.5 TEOM • Met Site: temperature, RH, precipitation, wind speed • Forecasts of inversion conditions • EPA PM2.5 standards 24/hr is 35 μg/m3, annual is 15 μg/m3

  9. Pre-Sampling • Initial meeting with participant • Discuss study and equipment • Keeping records of daily activities • Collect home information • Age of home, square footage, number of rooms • Wood type, cords burned per year, how long the wood was seasoned, how they acquire their wood

  10. Health Study • Participants monitor their asthmatic child’s breathing for up to 2 weeks • Use a PiKo-1 Electronic Peak Flow Meter • Measures how much air the child can take into the lungs and breathe out • Record measurements on data sheet • Survey about child’s physical activity and emotions related to their respiratory illness

  11. Indoor Air Sampling • Sample for 24-hour period, 2 to 4 sample days • Leland Sampler / Personal Environmental Monitor (PEM) with a quartz filter: • Organic Carbon / Elemental Carbon (OC/EC) • Chemical markers (vanillin, acetovanillone, guaiacol, 4-ethylguaiacol, levoglucosan, abietic acid, dehydroabietic acid) • DustTrak (continuous PM2.5 mass) set to run for 48 hours

  12. Sample Day: Intern • Equipment duties • Calibration and set-up • Cleaning • Record Keeping • Documenting equipment readings • Downloading & emailing DustTrak data to Tony Ward, University of Montana

  13. Indoor Sampling Equipment PEM Leland (inside) DustTrak

  14. Sample Day: Participant • Record of home activities • 2 pages: cooking, cleaning, candles, etc. • Nez Perce traditional burning (sweet grass, sage, patosway, or boiling of kouse kouse) • Record of wood burning activities • Loading and stoking • Size of logs and how many pieces used

  15. Old Stoves & Equipment

  16. Indoor PM2.5 Levels Prior to Changeout

  17. PM2.5 Pre Changeout 4,000 ug/m3

  18. Indoor and Outdoor PM2.5 Levels Prior to Changeout Lapwai indoor Kamiah indoor Outdoor

  19. The Changeout!

  20. New Stoves

  21. Indoor PM2.5 Levels Pre and Post Changeout

  22. PM2.5 Post Changeout 180 ug/m3

  23. Installation Inspection & Homeowner Training

  24. Happy Homeowners!

  25. Challenges • Sampling equipment malfunctions • Homeowners • Paperwork, no shows • Selecting 4 new homes mid-study • Distance to Kamiah • Wood stove business & installer • Distance (~200 miles away) • 2nd round of installations delayed two months due to snow • Attitude/not vested in the community

  26. Successes • Partnerships & intern participation • 16 tribal homes with EPA certified stoves • New stoves “burned off” before change out • Reduced indoor PM2.5 levels • Old stoves recycled • Installation inspection & training • Reduced ambient PM2.5 in each community • Interest outside of study communities • Future funding with the University of MT

  27. Sign on a participant’s front door www.nativeasthma.org

  28. Lessons Learned & Looking Forward • Installer • Purchase stoves from a local business • In a written agreement or in the bid • New stoves “burned off” pre-change out • Old stoves hauled to a recycler • Work towards having a tribal member become a National Fireplace Institute Certified Wood Burning Specialist • Homeowner • Written agreement about removing old stove • Wood stove fair in Fall ’08
