(a) The owner or operator of all units subject to the
emission specifications of this division shall test the units as follows.
(1) The units must be tested for nitrogen oxides (NOX ), carbon monoxide (CO), and oxygen (O2) emissions.
(2) Units that inject urea or ammonia into the exhaust
stream for NOX control must be tested
for ammonia emissions.
(3) Testing must be performed in accordance with the
schedules specified in §117.9130 of this title (relating to Compliance
Schedule for Dallas-Fort Worth Eight-Hour Ozone Nonattainment Area
Utility Electric Generation Sources).
(b) The tests required by subsection (a) of this section
must be used for determination of initial compliance with the emission
specifications of this division. Test results must be reported in
the units of the applicable emission specifications and averaging
periods. If compliance testing is based on 40 Code of Federal Regulations
Part 60, Appendix A reference methods, the report must contain the
information specified in §117.8010 of this title (relating to
Compliance Stack Test Reports).
(c) Continuous emissions monitoring systems (CEMS)
or predictive emissions monitoring systems (PEMS) required by §117.1340
of this title (relating to Continuous Demonstration of Compliance)
must be installed and operational before conducting testing under
subsection (a) of this section. Verification of operational status
must, at a minimum, include completion of the initial monitor certification
and the manufacturer's written requirements or recommendations for
installation, operation, and calibration of the device.
(d) Initial compliance with the emission specifications
of this division for units operating with CEMS or PEMS in accordance
with §117.1340 of this title must be demonstrated after monitor
certification testing using the NOX CEMS
or PEMS as follows.
(1) To comply with the NOX emission
specification in pounds per million British thermal units (lb/MMBtu)
on a rolling 30-day average, NOX emissions
from a unit are monitored for 30 consecutive unit operating days and
the 30-day average emission rate is used to determine compliance with
the NOX emission specification. The 30-day
average emission rate is calculated as the average of all hourly emissions
data recorded by the monitoring system during the 30-day test period.
(2) To comply with the NOX emission
specification in lb/MMBtu on a rolling 24-hour average, NOX emissions from a unit are monitored for 24
consecutive unit operating hours and the 24-hour average emission
rate is used to determine compliance with the NOX emission
specification. The 24-hour average emission rate is calculated as
the average of all hourly emissions data recorded by the monitoring
system during the 24-hour test period. Compliance with the NOX emission specification for fuel oil firing
must be determined based on the first 24 consecutive operating hours
a unit fires fuel oil.
(3) To comply with the NOX emission
specification in pounds per hour or parts per million by volume (ppmv)
at 15% O2 dry basis, on a block one-hour
average, any one-hour period while operating at the maximum rated
capacity, or as near thereto as practicable, after CEMS or PEMS certification
testing required in §117.1340 of this title is used to determine
compliance with the NOX emission specification.
(4) To comply with the NOX emission
specification in lb/MMBtu on a block one-hour average, any one-hour
period while operating at the maximum rated capacity, or as near thereto
as practicable, after CEMS or PEMS certification testing required
in §117.1340 of this title is used to determine compliance with
the NOX emission specification.
(5) To comply with the NOX emission
specification in pounds per megawatt-hour output on an annual average
basis, NOX emissions from the unit are
monitored in accordance with §117.1340(a) and (k) of this title.
The annual average is calculated as the average of all hourly emissions
data recorded by the monitoring system. The averaging period for demonstrating
initial compliance with the emission specification in §117.1310(a)(1)(C)
of this title (relating to Emission Specifications for Eight-Hour
Attainment Demonstration) is from March 1, 2009, through February
28, 2010.
(6) To comply with the NOX emission
specification in lb/MMBtu on a rolling 168-hour average, NOX emissions from all units in the system are
monitored for 168 consecutive unit operating hours and the 168-hour
average emission rate is used to determine compliance with the NOX emission specification. The 168-hour average
emission rate is calculated using the equation in §117.1310(a)(1)(D)
of this title by calculating the system-wide heat input weighted average
for each hour and then averaging the hourly data during the 168-hour
test period.
(7) To comply with the CO emission specification in
ppmv on a rolling 24-hour average, CO emissions from a unit are monitored
for 24 consecutive unit operating hours and the rolling 24-hour average
emission rate is used to determine compliance with the CO emission
specification. The rolling 24-hour average emission rate is calculated
as the average of all hourly emissions data recorded by the monitoring
system during the 24-hour test period.
