§ 74.23 - 1985 Allowable SO2 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:
(i) Allowable SO
Table 1—Factors to Convert Emission Limits to Pounds of SO
Unit measurement | Bituminous coal | Subbituminous coal | Lignite coal | Oil | lbs Sulfur/mmBtu | 2.0 | 2.0 | 2.0 | 2.0 | % Sulfur in fuel | 1.66 | 2.22 | 2.86 | 1.07 | ppm SO | 0.00287 | 0.00384 | 0.00167 | ppm Sulfur in fuel | 0.00334 | tons SO | 2 × 8760/(annual fuel consumption for specified year 1 × 10 3) | lbs SO | 8760/(annual fuel consumption for specified year 1 × 10 6) |

1 Annual fuel consumption as defined under § 74.20(b)(1) (i) or (ii); specified calendar year as defined under § 74.23(a)(2).
(ii) Citation of statute, regulations, and any other authority under which the allowable emissions rate under paragraph (a)(1) of this section is established as applicable to the combustion source;
(iii) Averaging time associated with the allowable emissions rate under paragraph (a)(1) of this section.
(iv) The annualization factor for the combustion source, based on the type of combustion source and the associated averaging time of the allowable emissions rate of the combustion source, as set forth in the Table 2 of this section:
Table 2—Annualization Factors for SO
Type of combustion source | Annualization factor for scrubbed unit | Annualization factor for unscrubbed unit | Unit Combusting Oil, Gas, or some combination | 1.00 | 1.00 | Coal Unit with Averaging Time ≤ 1 day | 0.93 | 0.89 | Coal Unit with Averaging Time = 1 week | 0.97 | 0.92 | Coal Unit with Averaging Time = 30 days | 1.00 | 0.96 | Coal Unit with Averaging Time = 90 days | 1.00 | 1.00 | Coal Unit with Averaging Time = 1 year | 1.00 | 1.00 | Coal Unit with Federal Limit, but Averaging Time Not Specified | 0.93 | 0.89 |

(2) Calendar year. (i) For combustion sources that commenced operation prior to January 1, 1985, the calendar year for the allowable SO
(ii) For combustion sources that commenced operation after January 1, 1985, the calendar year for the allowable SO
(iii) For combustion sources meeting the requirements of § 74.20(c), the calendar year for calculating the allowable SO
(b) 1985 Allowable SO
