  1. NonroadSources Melinda Ronca-Battista, ITEP

  2. NonroadMobile Sources • Any moving, motor-driven thing • Trains • Tractors • Construction equipment • ATVs, off-road motorcycles, boats • Doesn’t have to be a vehicle • Lawn and garden equipment • Generators • Irrigation pumps

  3. NonroadMobile Sources • Emissions from these vehicles usually estimated using EPA’s NONROAD model • Gives results only on state or county basis • Have to modify input files to run for reservation

  4. NONROAD MOBILE SOURCES (CONT.) • ITEP worked with several tribes and EPA’s OAQPS to find best way for tribes to estimate emissions from non-road sources • Developed table of emission factors, based on NONROAD model results • Can do calculation on paper or in spreadsheet, then enter results into TEISS

  5. What data do you need to collect? • Vehicle Types* • Population operating on reservation* • Average horsepower • Average hours each vehicle operates per year *Minimum information you must collect

  6. How to do the calculations? • Can you estimate annual hours of activity? • Get emission factors from ITEP for each vehicle type of interest EFpopulation x population = annual emissions OR EFactivity x hours = annual emissions Hours of activity gives a better estimate!

  7. NONROAD EXAMPLE 1 Survey finds 1,000 2-stroke, off-road motorcycles on your reservation. No info on how many hours per year each operates

  8. NONROAD EXAMPLE 2 Survey finds 1,000 2-stroke off-road motorcycles on your reservation. Each operates 104 hours per year x 1,000 vehicles = 104,000 hours

  9. NonroadHands-On • Nonroad calculation exercise handout
