WOODSTOVE CHANGEOUT ON THE
Johna Boulafentis & Tui Moliga Nez Perce Tribe Environmental Restoration and Waste Management Air Quality Program
Hypothesis Wood stove replacement will reduce indoor levels of PM and associated wood smoke chemical markers from domestic wood burning?
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
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
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 x23671
Outreach and Education Office Media –KLEW T.V. –Articles/Informational Notices –Letters & mass –Posters Field –Presentations & Air Quality Booth
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/m 3, annual is 15 μg/m 3
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
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
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
Sample Day: Intern Equipment duties –Calibration and set-up –Cleaning Record Keeping –Documenting equipment readings –Downloading & ing DustTrak data to Tony Ward, University of Montana
Indoor Sampling Equipment DustTrak PEM Leland (inside)
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

Installation Inspection & Homeowner Training
Happy Homeowners!
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) –2 nd round of installations delayed two months due to snow –Attitude/not vested in the community
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

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
