Code of Federal Regulations Title 40. Protection of Environment § 40.76.13 Compliance and excess emissions

(1) Calculate EE_i for each portion of the calendar year that the unit is subject to a different NO_X emission limitation:

where:

EE_i = Excess emissions for NO_X for the portion of the calendar year (in tons);

R_ai = 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 R_l is in effect;

R_li = 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, R_l, is in effect.

(2) If EE_i 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 EE_i = − 100, then EE_i = 0).

(3) Sum all EE_i values for the calendar year:

where:

EE = Excess emissions for NO_X for the year (in tons);

n = The number of time periods during which a unit is subject to different emission limitations;  and
