Section 117.2130 - Operating Requirements(a) The owner or operator shall operate any unit subject to the emission specifications of § 117.2110 of this title (relating to Emission Specifications for Eight-Hour Attainment Demonstration) in compliance with those specifications.(b) All units subject to § 117.2110 of this title must be operated so as to minimize nitrogen oxides (NO) 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 unit controlled with post-combustion control techniques must be operated such that the reducing agent injection rate is maintained to limit NO concentrations to less than or equal to the NO concentrations achieved at maximum rated capacity.(2) 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 O or CO control and maintains AFR in the range required to meet the engine's applicable emission specifications.(3) Each stationary internal combustion engine must be checked for proper operation according to §117.8140(b) of the title (relating to Emission Monitoring for Engines).(c) No person shall start or operate any stationary diesel or dual-fuel engine for testing or maintenance of the engine between the hours of 6:00 a.m. and noon, except: (1) for specific manufacturer's recommended testing requiring a run of over 18 consecutive hours;(2) to verify reliability of emergency equipment (e.g., emergency generators or pumps) immediately after unforeseen repairs. Routine maintenance such as an oil change is not considered to be an unforeseen repair; or(3) firewater pumps for emergency response training conducted in the months of April through October.30 Tex.
