RULE §117.3330Operating Requirements

(a) The owner or operator shall operate any stationary, reciprocating combustion engine subject to §117.3310 of this title (relating to Emission Specifications for Eight-Hour Attainment Demonstration) in compliance with the emission specifications of §117.3310 of this title.

(b) Each stationary, reciprocating combustion engine subject to §117.3310 of this title must be operated so as to minimize nitrogen oxides (NOX ) emissions, consistent with the emission control techniques selected, over the engine's operating or load range during normal operations. Such operational requirements include the following.

  (1) Each engine 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.

  (2) Each engine controlled with nonselective catalytic reduction must be equipped with an automatic air-fuel ratio (AFR) controller that operates on exhaust oxygen or carbon monoxide (CO) control basis and maintains the AFR in the range required to meet the engine's applicable emission specifications.

  (3) Each engine must be checked for proper operation by recorded NOX measurements according to §117.8140(b) of this title (relating to Emission Monitoring for Engines). The owner or operator of an engine subject to this paragraph is not required to perform the CO measurements under §117.8140(b) of this title. Engines equipped with a continuous emissions monitoring system or a predictive emissions monitoring system to monitor NOX are exempt from the requirements of this paragraph.
