Appendix C to Part 72 - Actual 1985 Yearly SO2 Emissions Calculation

The equation used to calculate the yearly SO2 emissions (SO2) is as follows:

SO2 = (coal SO2 emissions) + (oil SO2 emissions) (in tons)

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:

fuel SO2 emissions (in tons) = (yrly wtd. av. fuel sulfur %) × (AP-42 fact.) × (1−scrb. effic. %/100) × (units conver. fact.) × (yearly fuel burned)

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
Subbituminous 35
Lignite 30
