(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 datak = 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 gasFor 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, [GRAPHIC] [TIFF OMITTED] TR04AP95.004
(2) For a combustion source submitting annual data:
[GRAPHIC] [TIFF OMITTED] TR04AP95.005
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:[GRAPHIC] [TIFF OMITTED] TR04AP95.006 [60 FR 17115, Apr. 4, 1995, as amended at 63 FR 18841, Apr. 16, 1998] Sec. 74.23 1985 Allowable SO [bdi2] emissions rate.
(a) Data requirements. (1) The designated representative of the combustion source shall submit the following data and the calculations under paragraph (b) of this section based on the submitted data:
(1) The designated representative of the combustion source shall submit the following data and the calculations under paragraph (b) of this section based on the submitted data:
(i) Allowable SO2 emissions rate of the combustion source expressed in lbs/mmBtu as defined under Sec. 72.2 of this chapter for the calendar year specified in paragraph (a)(2) of this section. If the allowable SO2 emissions rate is not expressed in lbs/mmBtu, the allowable emissions rate shall be converted to lbs/mmBtu by multiplying the emissions rate by the appropriate factor as specified in Table 1 of this section.
