Drought Related Projects: Executive Order B-40-17 lifts the drought emergency in all California counties except Fresno, Kings, Tulare and Tuolumne, where emergency water-well drilling projects will continue to help address diminished groundwater supplies. For on-going and/or future groundwater projects in California counties other than the four listed above where portable equipment will be used, please contact the local air district for air quality permitting information.
Public Safety Power Shutoff (PSPS) Events: CARB regulations allow you to use your back-up generators during a Public Safety Power Shutoff.
