### “AcTuAL EMISSIONS” means the actual rate of EMISSIONS of a pollutant from an EMISSION UNIT, as determined in accordance with the following: (a) In general, ACTuAL EMISSIONS as of a particular date shall equal the average rate, in tons 

### peryear, atwhich the EMISSION UNIT actually emittedthe pollutant during 

### the two (2) year period which precedes the particular date and which is representative ofnormal source operation. The CoNTRoLOFFICER shall allow the use of a different time 

### period upon determination that it is more representative of normal source operation. AcTuAL EMIsSIONs shall be calculated using the EMISSION UNIT’S actual operating hours, production rates, and types of materials processed, stored, or combusted during the 

### selected time period. (b) The CONTROL OFFICER may presume that source specific ALLOWABLE EMISSIONS for an EMISSIONS UNIT are equivalent to the ACTUAL EMISSIONS of such EMISSIONUNIT. (c) For any EMISSION UNIT, except as specified in (d), which has notbegun normal operations on 

### the particulardate, AcTuAL EMISSIONS shall equal the PoTEr.m6L TO EMIT ofsuch EMISSIONUNITon thatdate. (d) For an ELECTRIC UTIuW STEAM GENERATING UNIT (otherthan a new unit orthe replacement of an existing unit) ACTUAL EMISSIONS of the unit following the physical or operational change shall equal the representative ActuAL EMISSIONS ofthe unit, provided the source owner or operator maintains and submits to the CoNTRoL OFFICER on an annual basis for a period offive (5) years from the date the unit resumes regular operation, information demonstrating that 

### the physical or operational change did 

### not result in an EMISSIONS increase. A longer period, not to exceed ten (10) years, may be required by the CONTROL OFFICER ifhe determines such a period to be more representative ofnormal source post-change operations.
