a. GHG calculated emissions are based on the following:

• Fuel usage for combustion sources shown in footnote a to Table 3.2-3.

• Workforce commuting:

1. Statistical information from U.S. Census Bureau indicates that 10.5 percent of U.S. residents carpool to work (USCB 2015). Number of WF3 employees as of January 2016 was 641.

Utilizing the 10.5 percent USCB carpool statistic, a value of "574 passenger vehicles per day was utilized.

2. The EPA's Greenhouse Gas Equivalencies Calculator shows that the CO2e/vehicle/year was estimated to be 4.75 metric tons (EPA 2015b).

3. Carbon dioxide has a global warming potential (100-year time horizon) of 1 based on Table A-1 to Subpart A of 40 CFR Part 98.

4. 573 vehicles x 4.75 metric tons CO2e/vehicle/year x 1 (global warming potential).
