40 CFR Appendix C to Part 72, Actual 1985 Yearly SO2 Emissions Calculation
The equation used to calculate the yearly SO2 emissions (SO2) is as follows:
If gas is the only fuel, gas emissions are defaulted to 0.
Each fuel type SO2 emissions is calculated on a yearly basis, using the equation:
For coal, the yearly fuel burned is in tons/yr and the AP-42 factor (which accounts for the ash retention of sulfur in coal), in lbs SO2 ton coal, is by coal type:
|Coal type||AP-42 factor|
|Bituminous, anthracite||39 lbs/ton|
For oil, the yearly fuel burned is in gal/yr. If it is in bbl/yr, convert using 42 gal/bbl oil. The AP-42 factor (which accounts for the oil density), in lbs SO2/thousand gal oil, is by oil type:
|Oil type||AP-42 factor|
|Distillate (light)||142 lbs/1,000 gal|
For all fuel, the units conversion factor is 1 ton/2000 lbs.
