Sec. 63.78  Early reduction demonstration evaluation.

    (a) The permitting authority will evaluate an early reduction 
demonstration submitted by the source owner or operator in a permit 
application with respect to the requirements of Sec. 63.74.
    (b) An application for a compliance extension may be denied if, in 
the judgement of the permitting authority, the owner or operator has 
failed to demonstrate that the requirements of Sec. 63.74 have been met. 
Specific reasons for denial include, but are not limited to:
    (1) The information supplied by the owner or operator is incomplete;
    (2) The required 90 percent reduction (95 percent in cases where the 
hazardous air pollutant is particulate matter) has not been 
demonstrated;
    (3) The base year or post-reduction emissions are incorrect, based 
on methods or assumptions that are not valid, or not sufficiently 
reliable or well documented to determine with reasonable certainty that 
required reductions have been achieved; or
    (4) The emission of hazardous air pollutants or the performance of 
emission control measures is unreliable so as to preclude determination 
that the required reductions have been achieved or will continue to be 
achieved during the extension period.
