San Diego County Air Pollution Control District-CALIFORNIA
DE MINIMIS EXEMPTIONS (Must Meet 1298):
Engines less than 50 hp or turbines less than 0.3 MW or smaller than 1 MMBtu/hr are exempt from permitting.
MINOR SOURCE PERMITTING:
New units must complete BACT for all criteria pollutants. The air district will basically follow CARB's recommended guidance, but may make stricter requirements depending on the outcome
of a health risk assessment. 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 |
The entire permitting process generally takes 3-4 months.
TREATMENT OF EMERGENCY ENGINES:
Emergency engines must obtain a permit. These units can only operate during emergencies and for maintenance and
will also receive an hourly operating limit of 200 hours per year. If the unit is found to be a health risk it
may be permitted for fewer hours.
