The definitions contained in section 25-7-103 shall apply to this part 12. In addition, the following definitions shall apply to this part 12:

1. (1) Actual emissions means the average amount of emissions, calculated in tons per year, that the stationary source or group of stationary sources emitted during the three-year period immediately prior to the date the proposed voluntary agreement was submitted to the division for review so long as the three-year time period is representative of normal unit operation. A different time period may be used to calculate actual emissions if such time period is more representative of normal unit operation than the three-year period immediately prior to the date the proposed voluntary agreement was submitted to the division.
2. (2) Actual emission rate means the average rate of emissions, calculated in pounds per million BTU or a comparable measure of the mass of emissions per unit of production, that the stationary source or group of stationary sources emitted during the three-year period immediately prior to the date the proposed voluntary agreement was submitted to the division for review so long as the three-year time period is representative of normal unit operation. A different time period may be used to calculate the actual emission rate if such time period is more representative of normal unit operation than the three-year period immediately prior to the date the proposed voluntary agreement was submitted to the division.
