2)         The owner or operator
must comply with the emission limitation set forth in subsection (e)(1) on a
30-operating day rolling average basis.  For purposes of this Subpart, an
operating day is a
calendar day in which any emission
unit addressed in subsection
(e)(1)
combusts
any fuel;
3)         Within 24 hours after
the end of each averaging period, the owner or operator must use the following
equation to determine the combined SO
2
emission rate of the emission
units addressed in subsection (e)(1) for each averaging period, which concludes
at the end of each operating day.  The SO
2
emission rate must not
exceed the limitation set forth in subsection (e)(1):
Where:
E
avg
=   SO
2
emission rate for the averaging period, in lb/hr.
E
h
=     SO
2
emission rate for stack operating hour "h" in the averaging period.
For purposes of this Subpart, a stack operating hour is a clock hour in which
valid data is obtained, and in which gases flow through the monitored stack or
duct for the emission units addressed in subsection (e)(1) (either for part of
the hour or for the entire hour) while at least one of the units is combusting
fuel.
n =       Number of
stack operating hours in the averaging period in which valid data is obtained.
4)         The SO
2
emission rate for the emission units addressed in subsection (e)(1) must not
exceed 6,000 lb/hr in more than 5% of the stack operating hours ("n"
in the equation in subsection (e)(3)) in any averaging period
the entire hour) while at least one of the units is combusting
fuel.
n =       Number of
stack operating hours in the averaging period in which valid data is obtained.
4)         The SO
2
emission rate for the emission units addressed in subsection (e)(1) must not
exceed 6,000 lb/hr in more than 5% of the stack operating hours ("n"
in the equation in subsection (e)(3)) in any averaging period.
f)         Midwest
Generation Will County                                          lb/hr
