Current through Reg. 49, No. 28; July 12, 2024
(a) Oxygen (O) monitors. If the owner or
					 operator installs an O monitor, the criteria in §
											117.8100(a)
					 of this title (relating to Emission Monitoring System Requirements for
					 Industrial, Commercial, and Institutional Sources) should be considered the
					 appropriate guidance for the location and calibration of the monitor.
(b) Nitrogen oxides (NO) monitors. If the
					 owner or operator installs a continuous emissions monitoring system (CEMS) or
					 predictive emissions monitoring system (PEMS), the CEMS or PEMS must meet the
					 requirements of §
											117.8100(a)
					 or (b) of this title. If a PEMS is used, the
					 PEMS must predict the pollution emissions in the units of the applicable
					 emission limitations of this division.
(c) Monitor installation schedule.
					 Installation of monitors must be performed in accordance with the schedule
					 specified in §
											117.9210
					 of this title (relating to Compliance Schedule for Dallas-Fort Worth Eight-Hour
					 Ozone Nonattainment Area Minor Sources).
(d) Testing requirements. The owner or
					 operator of any unit subject to §
											117.2110
					 of this title (relating to Emission Specifications for Eight-Hour Attainment
					 Demonstration) shall comply with the following testing requirements.
(1) Each unit must be tested for NO, carbon
					 monoxide (CO), and O emissions.
(2)
					 One of the ammonia monitoring procedures specified in §
												117.8130 of
					 this title (relating to Ammonia Monitoring) must be used to demonstrate
					 compliance with the ammonia emission specification of §
												117.2110(h)(2)
					 of this title for units that inject urea or ammonia into the exhaust stream for
					 NO control.
(3) For units not
					 equipped with CEMS or PEMS, all testing must be conducted according to §
												117.8000
					 of this title (relating to Stack Testing Requirements). In lieu of the test
					 methods specified in §
												117.8000
					 of this title, the owner or operator may use American Society for Testing and
					 Materials (ASTM) D6522-00 to perform the NO, CO, and O testing required by this
					 subsection on natural gas-fired reciprocating engines. If the owner or operator
					 elects to use ASTM D6522-00 for the testing requirements, the report must
					 contain the information specified in §
												117.8010
					 of this title (relating to Compliance Stack Test Reports).
(4) 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.
(5) For units
					 equipped with CEMS or PEMS, the CEMS or PEMS must be installed and operational
					 before testing under this subsection. 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.
(6) Initial compliance with the emission
					 specifications of §
												117.2110
					 of this title for units operating with CEMS or PEMS must be demonstrated after
					 monitor certification testing using the NO CEMS or PEMS.
(7) For units not operating with CEMS or
					 PEMS, the following apply.
(A) Retesting as
					 specified in paragraphs (1) - (4) of this subsection is required within 60 days
					 after any modification that could reasonably be expected to increase the NO
					 emission rate.
(B) Retesting as
					 specified in paragraphs (1) - (4) of this subsection may be conducted at the
					 discretion of the owner or operator after any modification that could
					 reasonably be expected to decrease the NO emission rate, including, but not
					 limited to, installation of post-combustion controls, low-NO burners, low
					 excess air operation, staged combustion (for example, overfire air), flue gas
					 recirculation, and fuel-lean and conventional (fuel-rich) reburn.
(C) Stationary, reciprocating internal
					 combustion engines not equipped with CEMS or PEMS must be periodically tested
					 for NO and CO emissions as specified in §
													117.8140(a)
					 of this title (relating to Emission Monitoring for Engines).
(8) Testing must be performed in
					 accordance with the schedule specified in §
												117.9210
					 of this title.
(9) All test reports
					 must be submitted to the executive director for review and approval within 60
					 days after completion of the testing.
(10) The owner or operator of an affected
					 unit in the Dallas-Fort Worth eight-hour ozone nonattainment area must submit
					 written notification of any CEMS or PEMS relative accuracy test audit (RATA) or
					 testing required under this section to the appropriate regional office and any
					 local air pollution control agency having jurisdiction at least 15 days in
					 advance of the date of RATA or testing.
