The Control Officer shall allo w the use of a different time period upon a determination that it is more representative of normal source operation. Actual emissi ons shall be calculated using the unit’s actual operating hours, production rates, and types of materials processed, stored, or combusted during the selected time period.

(b) If there is inadequate information to det ermine actual historical emissions, the Control Officer may presume that source-specific allowable emissions for the unit are equivalent to t he actual emissions of the unit.

unit on that date.

The determinat ion of cost effectiveness may consider the analysis
