I. What Action Is EPA Taking Today?

    We are proposing to approve new emissions tests averaging 
provisions for the state of Illinois. The IEPA submitted the provisions 
on October 9, 2001 as a requested revision to the Illinois SIP. The new 
provisions provide that when conducting a compliance test, a source is 
considered in compliance with the relevant standard if the average of 3 
emissions test runs is at or below the level specified in the emissions 
standard.
    The emissions tests averaging provisions only apply to units that 
produce a consistent pattern of emissions. The emissions tests 
averaging provisions may not be used for determining the compliance 
status of emissions units that are subject to Sections 111 (Standards 
of Performance for New Stationary Sources) and 112 (Hazardous Air 
Pollutants) of the Clean Air Act or for units that are being tested for 
emissions generated by hazardous waste or municipal waste.

II. Where Can I Find More Information About This Proposal and the 
Corresponding Direct Final Rule?

    For additional information see the direct final rule published in 
the rules section of this Federal Register.
