(Unit 6) combined

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.
