1. Go to the Data insert sheet by selecting the Data insert sheet tab below
10
11
(If you have a fuel type change AR, select the "Fuel Type Change" sheet, insert your current and proposed fuel types and usages, copy the produced emission changes table and paste it in your document)
12
Note that the fuel efficiency of a vehicle depends largely on the year it was manufactured in.
This tool calculates CO2 emissions for specific car models based on yearly driving habits.
13
-> If you are working on a fleet change AR, you may find AFLEET useful.

2.Type the name of your assessment recommendation in the red box
16
17
3. In the blue boxes input your gas and electricity savings for your Assessment recommendation
18
19
4. Determine what type of burner you have and select the appropriate burner from the green list (there are notes below that will help you make your choice). If you are unsure, talk to the air quality team.

5. Determine the non-attainment zone your facility is located in using the link below. It will be in the Wasatch Front (WF) non-attainment zone, Uinta Basin (UB) non-attainment zone, both, or neither.

6. If the facility is in the WF non-attainment zone select the tab WFZ. If the facility is in the UB non-attainment zone select the tab UBZ. If the facility is in both nonattainment zones select the tab Both.
26
If the facility is in neither zone select the tab General.
27
28
7. In the tab you chose namely WFZ, UBZ, Both or General you will see a series of tables with emission savings. There will be three tables for your AR that you can choose from.
29
The tables that correspond to your AR will have the same name that you inserted in the red box in step 2. The AR name will be highlighted in yellow in each of your three tables.
30
31
8. The three tables are as follows one will be both a gas and electricity savings table if your AR has both types of savings. Two will be a gas savings only table that you can use if you only have gas savings in your AR.
32
Three will be a electricity savings table that you can use if you only have electricity savings in your AR. Copy the appropriate table for your AR and paste it into your report.

34
To Find the Total Emissions Savings
35
36
1. Follow steps 1-4 from for a single AR for each assessment recommendation performed by the team. For each additional AR (up to 12) input the electricity and natural gas savings that correspond to each AR.
37
(If there are more than 12 ARs please contact the air quality team)
38
39
2. follow step 5 and 6 from for a single AR
40
3. Directly right of the first AR table will be a table that has calculated the total emissions savings on the assessment it is titled TOTAL ASSESSMENT EMISSIONS SAVINGS copy and paste this table into the appropriate section
41
(You can also use either the gas savings only table, the electricity savings only table or the condensed table to report the total amount)
