PART 76--ACID RAIN NITROGEN OXIDES EMISSION REDUCTION PROGRAM--Table of Contents
 
Sec. 76.13  Compliance and excess emissions.

    Excess emissions of nitrogen oxides under Sec. 77.6 of this chapter 
shall be calculated as follows:
    (a) For a unit that is not in an approved averaging plan:
    (1) Calculate EEi for each portion of the calendar year 
that the unit is subject to a different NOX emission 
limitation:

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 Sec. 76.5, 76.6, or 76.7 or as determined under 
Sec. 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.

    (2) If EEi is a negative number for any portion of the 
calendar year, the EE value for that portion of the calendar year shall 
be equal to zero (e.g., if EEi = -100, then EEi = 
0).
    (3) Sum all EEi values for the calendar year:

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

    (b) For units participating in an approved averaging plan, when all 
the requirements under Sec. 76.11(d)(1) are not met,

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 Sec. 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.
