Current through Reg. 49, No. 28; July 12, 2024
(a) The owner
					 or operator shall operate any unit subject to the emission specifications of
					 §
											117.105
					 of this title (relating to Emission Specifications for Reasonably Available
					 Control Technology (RACT)) in compliance with those specifications.
(b) The owner or operator shall operate any
					 unit subject to the plant-wide emission specification of §
											117.115
					 of this title (relating to Alternative Plant-Wide Emission Specifications) such
					 that the assigned maximum nitrogen oxides (NOX) emission
					 rate for each unit expressed in units of the applicable emission specification
					 and averaging period, is in accordance with the list approved by the executive
					 director pursuant to §
											117.152
					 of this title (relating to Final Control Plan Procedures for Reasonably
					 Available Control Technology).
(c)
					 The owner or operator shall operate any unit subject to the source cap emission
					 limits of §
											117.123 of
					 this title (relating to Source Cap) in compliance with those
					 limitations.
(d) All units subject
					 to §§117.105, 117.110(a), 117.115, or 117.123 of this title (relating
					 to Emission Specifications for Reasonably Available Control Technology (RACT);
					 Emission Specifications for Attainment Demonstration; Alternative Plant-Wide
					 Emission Specifications; and Source Cap) must be operated so as to minimize
					 NOX emissions, consistent with the emission control
					 techniques selected, over the unit's operating or load range during normal
					 operations. Such operational requirements include the following.
(1) Each boiler, except for wood-fired
					 boilers, must be operated with oxygen (O2), carbon
					 monoxide (CO), or fuel trim.
(2)
					 Each boiler and process heater controlled with forced flue gas recirculation
					 (FGR) to reduce NOX emissions must be operated such that
					 the proportional design rate of FGR is maintained, consistent with combustion
					 stability, over the operating range.
(3) Each boiler and process heater controlled
					 with induced draft FGR to reduce NOX emissions must be
					 operated such that the operation of FGR over the operating range is not
					 restricted by artificial means.
(4)
					 Each unit controlled with steam or water injection must be operated such that
					 injection rates are maintained to limit NO X
					 concentrations to less than or equal to the NO X
					 concentrations achieved at maximum rated capacity (corrected to 15%
					 O2 on a dry basis for stationary gas
					 turbines).
(5) Each unit controlled
					 with post-combustion control techniques must be operated such that the reducing
					 agent injection rate is maintained to limit NOX
					 concentrations to less than or equal to the NOX
					 concentrations achieved at maximum rated capacity.
(6) Each stationary internal combustion
					 engine controlled with nonselective catalytic reduction must be equipped with
					 an automatic air-fuel ratio (AFR) controller that operates on exhaust
					 O2 or CO control and maintains AFR in the range required
					 to meet the engine's applicable emission specifications.
(7) Each stationary internal combustion
					 engine must be checked for proper operation of the engine according to §
												117.8140(b)
					 of this title (relating to Emission Monitoring for Engines).
