  1. Collecting and Entering Data for Nonpoint Sources Melinda Ronca-Battista and Angelique Luedeker ITEP/TAMS Center

  2. Homework Discussion Are there any questions on the homework of the list of nonpoint sources and the data you need to collect for those sources?

  3. Common Nonpoint Sources Most Reservations Have These Sources Residential Heating Commercial Heating Paved Road Dust Unpaved Road Dust Gas Stations

  4. Gathering Data Local data sources are usually the most accurate If you are not able to obtain data from local sources, there are options of obtaining data from national sources, such as the U.S. Census Bureau Usually, you can find these data online

  5. Residential Heating Data Collection-Step 1 Determine what fuels are used Check with the tribal housing office Look online at U.S. Census Bureau data: http://factfinder2.census.gov

  6. Using U.S. Census Bureau FactFinder To find home heating fuel data In opening screen, select Guided Search, then Get Me Started

  7. U.S. Census Bureau FactFinder Check the “I’m looking for information about housing” radio button, then click Next

  8. U.S. Census Bureau FactFinder Expand Physical Characteristic entry by clicking on plus sign Select Heating Fuel by clicking on it Then click Next

  9. U.S. Census Bureau FactFinder Click on drop-down arrow of Select a geographic type field Select American Indian Area/Alaska Native Area/Hawaiian Home Land This brings up a list of tribes, click on your tribe, click on Add To Your Selections button, then click Next

  10. U.S. Census Bureau FactFinder In this screen, click on Skip This Step button In the next screen, select most recent House Heating Fuel dataset

  11. U.S. Census Bureau FactFinder Results The House Heating Fuel table comes up For this location, estimate emissions for these fuel types: Utility gas (natural gas) Bottled, tank, or LP gas (LPG) Fuel Oil Wood Electricity does not produce emissions at residential level Coal use is minimal in this area, estimate of only 2 houses

  12. Residential Heating Data Collection-Step 2 Look at TEISS calculators to determine what data you need to collect Each heating source calculator asks for amount of fuel used reservation wide, remember to check units Use the Print Blank option If not clear on what to enter into a field, check source documents referenced on opening screen of calculator It is a good idea to read source documents before using calculator

  13. Residential Heating Data Collection-Step 3 Determine quantity of each fuel used reservation wide Check with tribal housing office or local fuel suppliers Conduct a survey You might survey a few houses and use average response as representative of the reservation per household value Use 2009 Energy Information Administration (EIA) data: http://www.eia.gov/consumption/residential/data/2009/index.cfm?view=consumption#fuel-consumption

  14. EIA Data Find Fuel Consumption table for your area, click on XLS icon to open it

  15. EIA Data In spreadsheet that opens, click on Physical Units tab to open that worksheet This shows average per household fuel use based on different categories

  16. Example: Natural Gas, Mostly Local Data Called local natural gas company and asked several questions Q: In 2011 (inventory year), how much gas was sold to reservation households? A: 900,000 cubic feet of gas Q: What is the heating value of the gas you sell? A: 980 Q: Can you specify the units of that value? A: BTU/ft3 Q: What is the sulfur content of the gas you sell? A: I do not know

  17. Example: Natural Gas Calculator Selected combustor type of residential furnaces Converted 900,000 ft3 to 0.9 million ft3 Entered heating value of 980 BTU/ft3 No emission controls for residential Left sulfur content unknown selection

  18. Example: Woodstoves, Some Local Data Surveyed 100 households on how much wood burned annually per household, received 50 responses Entered responses into spreadsheet to calculate annual average wood consumption per household of 1.2 cords House Heating Fuel table from U.S. Census reports 900 households on the reservation heat with wood Calculated reservation wide annual wood consumption for residential heating as 1080 cords 900 households x 1.2 cords/household = 1080 cords

  19. Example: Woodstoves Calculator Selected units of cords Selected stove type of catalytic, phase II based on discussion with housing office Selected wood type based on local knowledge Entered amount of fuel burned of 1080 cords

  20. Example: LPG , No Local Data House Heating Fuel table from U.S. Census reports 335 households on the reservation heat with LPG EIA Data For this example, the reservation is located in Idaho EIA data reports a Q for Idaho LPG household consumption, meaning data withheld Instead use value for Climate Region of Very Cold/Cold of 604 gallons/household Calculated reservation wide annual LPG consumption for residential heating as 202,340 gallons 335 households x 604 gal/household = 202,340 gallons

  21. Example: LPG Calculator Selected LPG type of propane based on local knowledge Selected process of residential use Converted 202,340 gal to 202.34 thousand gal Left sulfur content unknown selection

  22. Internet Data for Other Sources Remember, local data is usually more accurate Commercial Heating The EIA also has commercial data at http://www.eia.gov/consumption/commercial/data/2003/index.cfm?view=consumption Includes energy intensity data for some fuel types, for example, Table C35 shows average gallons/square foot values for fuel oil If you know the square footage of the building, you could estimate the fuel usage

  23. Internet Data for Other Sources (cont.) Road Dust Check state Department of Transportation or Department of Motor Vehicles websites for traffic count data Data for reservation roads might not be available, but might be able to estimate traffic counts based on roads that are near Traffic counts usually reported as average daily traffic (ADT) counts Estimate total road lengths from maps

  24. Internet Data for Other Sources (cont.) Gas Stations U.S. Census Bureau FactFinder Table EC0744A1 reports number of gas stations and total sales value per county In FactFinder Advanced Search, type in table number and county Select an Industry Code of 447 Calculate an average sales value per gas station Divide average sales value by gasoline price per gallon to estimate how much gasoline is sold per gas station This is a rough estimate

  25. Homework due in 10 days: Collect data for a nonpoint source in your list of sources to include in your EI If you cannot collect local data, estimate data from internet sources Remember, you can always update your data in TEISS if you can collect local data at some point Enter this source into the TEISS project that you started for your reservation during first training Use the appropriate TEISS calculator to estimate emissions for this source Email a TEISS report showing data entered to instructors
