Excess emissions of nitrogen oxides under § 77.6 of this chapter shall be calculated as follows:
where:
EEi = Excess emissions for NOX for the portion of the calendar year (in tons);
Rai = Actual average emission rate for the unit (in lb/mmBtu), determined according to part 75 of this chapter for the portion of the calendar year for which the applicable emission limitation Rl is in effect;
Rli = Applicable emission limitation for the unit, (in lb/mmBtu), as specified in § 76.5 , 76.6 , or 76.7 or as determined under § 76.10 ;
HIi = Actual heat input for the unit, (in mmBtu), determined according to part 75 of this chapter for the portion of the calendar year for which the applicable emission limitation, Rl, is in effect.
where:
EE = Excess emissions for NOX for the year (in tons);
n = The number of time periods during which a unit is subject to different emission limitations; and
where:
EE = Excess emissions for NOX for the year (in tons);
Rai = Actual annual average emission rate for NOX for unit i, (in lb/mmBtu), determined according to part 75 of this chapter;
Rli = Applicable emission limitation for unit i, (in lb/mmBtu), as specified in § 76.5 , 76.6 , or 76.7 ;
HIi = Actual annual heat input for unit i, mmBtu, determined according to part 75 of this chapter;
n = Number of units in the averaging plan.
