# §76.13. Compliance and excess emissions.


Excess emissions of nitrogen oxides under [§ 77.6](/cfr/40/77.6.md) 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:
  - (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 EE<I>i</I> values for the calendar year—**
- (b) For units participating in an approved averaging plan, when all the requirements under [§ 76.11(d)(1)](/cfr/40/76.11.md?p=d-1) are not met,
