MINOR SOURCE PERMITTING

The district does not have any rules for addressing these units. Officials won't require offsets, but BACT level of controls are very likely at 150 pounds of NOx per day. Permitting officials feel that there is so much geothermal power available in the area that other types of generators are very unlikely.

TREATMENT OF EMERGENCY ENGINES

Emergency units will likely be given an hourly limit, but there are no official regulations established. CARB Air Toxic Control Measures for Stationary Compression Engines apply (see the CA state page for more information).
