Current through Reg. 49, No. 28; July 12, 2024
(a) Oxygen (O2)
					 monitors. If the owner or operator installs a continuous emissions monitoring
					 system (CEMS) to monitor O2, the CEMS must meet the
					 requirements of §
											117.8100(a)
					 of this title (relating to Emission Monitoring System Requirements for
					 Industrial, Commercial, and Institutional Sources).
(b) Nitrogen oxides
					 (NOX) monitors. If the owner or operator installs a CEMS
					 or predictive emissions monitoring system (PEMS) to monitor
					 NOX, the CEMS or PEMS must meet the requirements of
					 §
											117.8100(a)
					 or (b) of this title, as
					 applicable.
(c) Monitor
					 installation schedule. If the owner or operator elects to installs CEMS or PEMS
					 to monitor NOX or O2 as provided
					 in subsections (a) and (b) of this section, installation and certification of
					 monitoring systems must be performed in accordance with the schedule specified
					 in §
											117.9340
					 of this title (relating to Compliance Schedule for East Texas
					 Combustion).
(d) Testing
					 requirements. The owner or operator of any stationary, reciprocating combustion
					 engine subject to §
											117.3310
					 of this title (relating to Emission Specifications for Eight-Hour Attainment
					 Demonstration) shall comply with the following testing requirements.
(1) Each engine must be tested for NO
					 X and O2 emissions.
(2) Each engine that injects urea or ammonia
					 into the exhaust stream for NOX control must be tested
					 for ammonia emissions.
(3) For
					 engines 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 NOX and
					 O2 testing required by this subsection on natural
					 gas-fired reciprocating internal combustion 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.
(5) For engines equipped
					 with CEMS or PEMS, the CEMS or PEMS must be installed and operational before
					 conducting 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) For engines operating with CEMS or PEMS,
					 initial compliance with the emission specifications of §
												117.3310
					 of this title may be demonstrated by using the CEMS or PEMS, after monitor
					 certification testing, in lieu of the methods specified in §
					 117.3335(d)(3) of this title (relating to Monitoring, Notification, and Testing
					 Requirements).
(7) For engines not
					 operating with CEMS or PEMS, periodic testing for NOX
					 emissions must be conducted according to §
												117.8140(a)
					 of this title (relating to Emission Monitoring for Engines).
(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 NOX
					 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 NOX emission
					 rate, including, but not limited to, installation of post-combustion controls
					 or low-NOX burners, low excess air operation, staged
					 combustion (for example, overfire air), flue gas recirculation, and fuel-lean
					 and conventional (fuel-rich) reburn.
(8) Testing must be performed in accordance
					 with the schedule specified in §
												117.9340
					 of this title.
