applicable requirements from the related construction permit
for the Gateway Energy & Coke Co. plant.
The EPA administrator directed
the Illinois EPA to specify emission factors or equations that
U.S. Steel intends to use to demonstrate compliance with
emission limits and how compliance will be determined, or

permit, and suggested the Illinois EPA revise language in the
permit to clarify emission limits.

Steels application for permission to continue operating
during start-up, breakdowns and malfunction events did not
include all the information required by the state
