# V. INITIAL PERFORMANCE TESTING REQUIREMENTS: A. The Pe rmittee shall perform stack sampling and other testing
to estab

li sh the act u al pattern
an d quantities

of air contaminants being emi tted into the atmosphere from th e turbine
(E PN TURB

I) and to determine
the initial compliance with th e 

# C02 emission limits

e st ablishe

d in this permit. Sampling shall be conducted

in accordance with 40 CFR 

# § 60.8 and EPA Method
3a or 3b for the concentration

of 

# C02. The stack test sha ll consist of three separate runs at or above 90% of maximum load operations and three separate runs below 70% but above 50% load operation. Stack gas tlow rat e measurements

, as we

: ll as moisture measurements

(if needed),

s h a ll be made during each test run. The

e ) ectdcal generation (gross megawatts) during eac h test run sha ll al so be recorded

. The 

# C02 emission rate shall be calculated

as defin ed below and recorde

d for each te s t run in
I b C0
2 /MWh (gross) and Ib COVhr

. The arithmetic mean for the thre

e test runs at or abov

e 90% of maximum load operation and the arithmetic mean for the

t h ree test runs below 70% but above 50% load operation

s hall also be calculated and rec o rded.l. The C02 hourly average emission rate determined

by the three runs below
at or above 90% of maximwn load multiplied

by 4
, 572 hours

. 2.

f f the above calculated C02 em

i ssion total does not exceed the TPY limit specified
on Table

1, no com plian ce strategy needs to be developed. 3.
If the above calcu

l ated C02 emission total exceeds the TPY limit speci fied in Table

1 , the facility shall: a. Document
the exceedance

in the test report; and b
. Exp lain within the report how the facility will assure compliance with the C02 emission limit listed in Ta bl e 1. B. Within 60 days after achieving
the maximum production

r ate at which the affected facility will be operated, but not later than

1 80 day

s after initial startup of the facility, performance test(s) sha11 be conducted and

a written report of the perfom1ance testing results furnished

to EPA. Additional sampling may be required
by TCEQ
or EPA. C. Permittee sha ll s ubmit

a performance

te st protocol

to EPA no later than 30 days prior to the test to ali ow review of the test plan and to arrange for an observer

to be present

at the t est. The performance
test shalll be conducted

in acco rd a n ce with the

s ubmitted protocol, and any changes

r equired by E: P A. D. Performance

te sts shall be co ndu cted under such condition

s to ensure representative pe rf ormance
of the affected facility. The Permittee

s hall make available

to EPA such records
as may be necessary

to det ermine the conditio

n s of th e performance tests. E. The Permittee
sha ll provide EPA at lea st 30 days' prior notice of any performance test, except
as specified under other sub part s, to afford EPA the opportunity

to have an observer present and/or
to attend

a pre-test meeting.

I f there
is a delay in the original test date

, the facility must provide

at least

7 days prior notice of the

r esche duled date of the performance

test unless EPA aJpproves

an earlier rescheduled date due to unforeseen events, such as delays that are caused by weather

. F. The Permittee shall provide,

or cause to be provided, performance testing facilities

as follows: l. Samp lin g ports adequate
for

t es
t methods applicab

le to this facility, 2. Safe sampling platform(s), 3. Safe access
to sampling platform(s)

, and 4
. Utilities
for samp ling and testing equipment. G. Emiss

i on testing

fo r the turbine shall be performed every five years, plus

o r minus

6 month

s , from when the previous performance
test was performed

t o verify continued performance

at permitted emiss ion limits

.
