Sec. 75.40  General demonstration requirements.


    (a) The owner or operator of an affected unit, or the owner or 
operator of an affected unit and representing a class of affected units 
which meet the criteria specified in Sec. 75.47, required to install a 
continuous emission monitoring system may apply to the Administrator for 
approval of an alternative monitoring system (or system component) to 
determine average hourly emission data for SO2, 
NOx, and/or volumetric flow by demonstrating that the 
alternative monitoring system has the same or better precision, 
reliability, accessibility, and timeliness as that provided by the 
continuous emission monitoring system.
