Feather River Air Quality Management District-CALIFORNIA
DE MINIMIS EXEMPTIONS (Must Meet 1298):
Units with a potential to emit 2 pounds per day or less are exempt from permitting
MINOR SOURCE PERMITTING:
All units with a potential to emit greater than 25 pounds per day of a criteria pollutant will be required to apply
BACT. The air district follows CARB's
guidance for permitting of electric generating technologies. 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 |
Engines that do not trigger BACT must meet a 20% opacity limit, but no other emission limitations have been
established.
The permitting process generally takes about a month, but there is an expedite option available for a fee.
TREATMENT OF EMERGENCY ENGINES:
Emergency engines are permitted normally. Permits will typically include an hourly operating limit for overall
use, which means that units are not limited operation during emergencies only.
