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.
