(a) The owner or operator of any unit subject to the
emission specifications of this division shall test the unit as follows.
(1) The unit must be tested for nitrogen oxides (NOX ), carbon monoxide (CO), and oxygen (O2) emissions while firing gaseous fuel or,
as applicable, liquid and solid fuel.
(2) Units that inject urea or ammonia into the exhaust
stream for NOX control must be tested
for ammonia emissions.
(3) Initial demonstration of compliance testing must
be performed in accordance with the schedule specified in §117.9030
of this title (relating to Compliance Schedule for Dallas-Fort Worth
Eight-Hour Ozone Nonattainment Area Major Sources).
(b) The initial demonstration of compliance tests required
by subsection (a) of this section must use the methods referenced
in subsection (d) or (e) of this section and 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.
(c) Any continuous emissions monitoring system (CEMS)
or any predictive emissions monitoring system (PEMS) required by §117.440
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 or system.
(d) Compliance with the emission specifications of
this division for units operating without CEMS or PEMS must be demonstrated
according to the requirements of §117.8000 of this title (relating
to Stack Testing Requirements).
(e) Initial compliance with the emission specifications
of this division for units operating with CEMS or PEMS in accordance
with §117.440 of this title, must be demonstrated after monitor
certification testing using the CEMS or PEMS as follows.
(1) For boilers and process heaters complying with
a NOX emission specification in pounds
per million British thermal units (lb/MMBtu) on a rolling 30-day average,
NOX emissions from the unit are monitored
for 30 successive 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) For units complying with a NOX emission
specification on a block one-hour average, any one-hour period while
operating at the maximum rated capacity, or as near thereto as practicable
is used to determine compliance with the NOX emission
specification.
(3) For units complying with a CO emission specification,
on a rolling 24-hour average, any 24-hour period is used to determine
compliance with the CO emission specification.
(4) For units complying with §117.423 of this
title (relating to Source Cap) a rolling 30-day average of total daily
pounds of NOX emissions from the units
are monitored (or calculated in accordance with §117.423(c) of
this title) for 30 successive source operating days and the 30-day
average emission rate is used to determine compliance with the NOX emission limit. The 30-day average emission
rate is calculated as the average of all daily emissions data recorded
by the monitoring and recording system during the 30-day test period.
There must be no exceedances of the maximum daily cap during the 30-day
test period.
(f) Compliance stack test reports must include the
information required in §117.8010 of this title (relating to
Compliance Stack Test Reports).
