methods
specified
in
the
Division's
Procedures

The
methods
for
the
determination
of
compliance
with
emission
limits
listed
under
Sections
3.2,
3.3,
and
3.4
which
pertain
to
the
emission
units
listed
in
Section
3.1
are
as

shall
be
used
for
the
determination
of
concentration
of
carbon
monoxide.
The
sampling
time
for
each
run
shall
be
one
hour.

5.2.1
The
Permittee
shall
install,
calibrate,
maintain,
and
operate
a
system
to
continuously
monitor
and
record
the
indicated
pollutants
on
the
following
equipment.
Each
system
shall
meet
the
applicable
performance
specification(

a.
The
cylinder
gas
audit
(
CGA)
is
only
required
to
be
conducted
in
a
calendar
quarter
if
the
turbine
is
operated
during
the
quarter.

b.
A
Relative
Accuracy

Audit
(
RATA)
shall
be
conducted
annually
or
every
four
operating
quarters
(
not
to
exceed
eight
calendar
quarters),
whichever
is
greater.
For
the
purpose
of
this
condition
an
operating
quarter
is
defined
as
any
calendar
quarter
during
which
the
turbine
is
operated.

5.2.8
The
Permittee
shall
obtain
CO
emissions
data
for
at
least
75
percent
of
the
operating
hours
for
each
turbine
during
each
calendar
month
that
a
turbine
is
operated.
If
this
minimum
data
requirement
is
not
met
using
the
CO
CEMS
required
by
Condition
Nos.
5.2.1.
b,
the
Permittee
may
supplement
the
emissions
data
with
data
obtained
by
conducting
sampling
using
the
methods
prescribed
in
Condition
4.1.3.
