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?

Gathering Data

Local data sources are usually the most accurateIf 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 11. 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 dataIn 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 itThen 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

In the next screen, select most recent House Heating Fuel dataset

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 OilWood

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

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

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 DataIn 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 CalculatorSelected 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 cords900 households x 1.2 cords/household = 1080 cords

19

Example: Woodstoves CalculatorSelected units of cordsSelected 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 DataHouse Heating Fuel table from U.S. Census reports 335

households on the reservation heat with LPGEIA Data

For this example, the reservation is located in IdahoEIA data reports a Q for Idaho LPG household consumption,

meaning data withheldInstead use value for Climate Region of Very Cold/Cold of

604 gallons/householdCalculated reservation wide annual LPG consumption for

residential heating as 202,340 gallons335 households x 604 gal/household = 202,340 gallons

21

Example: LPG CalculatorSelected 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 accurateCommercial 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 DustCheck 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)

countsEstimate total road lengths from maps

24

Internet Data for Other Sources (cont.)

Gas StationsU.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 stationDivide average sales value by gasoline price per gallon to

estimate how much gasoline is sold per gas stationThis is a rough estimate

Homework due in 10 days:Collect data for a nonpoint source in your list of sources

to include in your EIIf you cannot collect local data, estimate data from internet

sourcesRemember, you can always update your data in TEISS if you

can collect local data at some pointEnter this source into the TEISS project that you started

for your reservation during first trainingUse the appropriate TEISS calculator to estimate

emissions for this sourceEmail a TEISS report showing data entered to instructors
