RULE §117.130Operating Requirements

(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).
