MINOR SOURCE PERMITTING:

The district has never permitted a minor source electric generating facility. There are no specific rules established, but the district would require BACT based on CARB's guidance. Sample BACT for control of NOx from turbines and internal combustion engines is as follows:

Size of Unit Level of Control (ppm)
>3 MW 9
3-12 MW simple cycle 2.5
3-12 MW combined cycle 5
12-50 MW simple cycle 2.5
12-50 MW combined cycle 5
IC Engines 9


TREATMENT OF EMERGENCY ENGINES:

An emergency engine would likely be exempted from permitting, but no requirements have been established.
