MINOR SOURCE PERMITTING

Every source must apply for a permit, but the permitting authority will determine whether the unit will have a significant air quality impact. Modeling will be completed by the permitting department and any necessary controls will be determined based on the results. Sources with emissions greater than 2,500 pounds per day of CO or 250 of any other criteria pollutants triggers BACT. There is no official BACT cost threshold established and no specific examples of required technologies were available. Beyond BACT requirements there are no specific emission requirements in the district rules. All other requirements will be determined on a case by case basis.

The entire permitting process can take from 1 day to 1 year as there is only one staff person to handle all permits.

TREATMENT OF EMERGENCY ENGINES

There is no special treatment for emergency engines. CARB Air Toxic Control Measures for Stationary Compression Engines apply (see the CA state page for more information).
