San Luis Obispo County Air Pollution Control District-CALIFORNIA
DE MINIMIS EXEMPTIONS (Must Meet 1298):
Engines less than 50 hp or turbines less than 3 MMBtu/hr. Any unit with uncontrolled emissions less than 2 lb/day
or burning natural gas or liquid petroleum gas and smaller than 2 MMBtu/hr and some standby engines.
MINOR SOURCE PERMITTING:
The air district follows CARB's
guidance for permitting of electric generating technologies. This guidance recommends BACT for all
criteria pollutants. 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 |
Additional limitations may be required by the air district based on any health risks imposed by the project.
The entire permitting process generally takes between 2-6 months. There is a 30-day comment period for projects
over 100 lbs/day of any criteria pollutant.
TREATMENT OF EMERGENCY ENGINES:
Emergency engines must be permitted. Units will receive an hourly operating limit based factors such as the health
risk and location of the project. Projects could be permitted to operate up to 200 hours, but only during emergencies
and for maintenance.
