        Subpart C--Allowance Calculations for Combustion Sources
 
Sec. 74.22  Actual SO2 emissions rate.

    (a) Data requirements. The designated representative of a combustion 
source shall submit the calculations under this section based on data 
submitted under Sec. 74.20 for the following calendar year:
    (1) For combustion sources that commenced operation prior to January 
1, 1985, the calendar year for calculating the actual SO2 
emissions rate shall be 1985.
    (2) For combustion sources that commenced operation after January 1, 
1985, the calendar year for calculating the actual SO2 
emissions rate shall be the first year of the three consecutive calendar 
years of the alternative baseline under Sec. 74.20(b)(2).
    (3) For combustion sources meeting the requirements of 
Sec. 74.20(c), the calendar year for calculating the actual 
SO2 emissions rate shall be the first year of the three 
consecutive calendar years to be used as alternative data under 
Sec. 74.20(c).
    (b) SO2 emissions factor calculation. The SO2 
emissions factor for each type of fuel consumed during the specified 
year, expressed in pounds per thousand tons for coal, pounds per 
thousand barrels for oil and pounds per million cubic feet (scf) for 
gas, shall be calculated as follows:

SO2 Emissions Factor = (average percent of sulfur by weight) 
    x (k),

where,

average percent of sulfur by weight
    = annual average, for a combustion source submitting annual data
    = monthly average, for a combustion source submitting monthly data
k = 39,000 for bituminous coal or anthracite
    = 35,000 for subbituminous coal
    = 30,000 for lignite
    = 5,964 for distillate (light) oil
    = 6,594 for residual (heavy) oil
    = 0.6 for natural gas
For other fuels, the combustion source must specify the SO2 
emissions factor.

    (c) Annual SO2 emissions calculation. Annual 
SO2 Emissions for the specified calendar year, expressed in 
pounds, shall be calculated as follows:
    (1) For a combustion source submitting monthly data,

    (2) For a combustion source submitting annual data:

where,

``quantity of fuel consumed'' is as defined under Sec. 74.20(a)(2)(i);
``SO2 emissions factor'' is as defined under paragraph (b) of 
this section;
``control system efficiency'' is as defined under Sec. 60.48(a) and part 
60, appendix A, method 19 of this chapter, if applicable; and
``fuel pre-treatment efficiency'' is as defined under Sec. 60.48(a) and 
part 60, appendix A, method 19 of this chapter, if applicable.

    (d) Annual fuel consumption calculation. Annual fuel consumption for 
the specified calendar year, expressed in mmBtu, shall be calculated as 
defined under Sec. 74.20(b)(1) (i) or (ii).
    (e) Actual SO2 emissions rate calculation. The actual 
SO2 emissions rate for the specified calendar year, expressed 
in lbs/mmBtu, shall be calculated as follows:
