With the potential for Public Safety Power Shutoffs (PSPS) during wildfire season, the Air Pollution Control District (APCD) wants to remind you about requirements related to backup diesel generators. Diesel generators require an APCD permit (as mandated by the State) due to the fact that diesel exhaust contains toxic air contaminants and has been linked to cancer and other adverse health effects.
If you’re looking to purchase a diesel generator that’s bigger than you could carry (50 bhp or greater), an APCD permit may be required before you install and operate the generator. Therefore, before you purchase or rent a generator, please contact engr@sbcapcd.org for more info on how to navigate the requirements. Please also see these resources for more information:

Backup diesel generators aren’t for everyone and alternatives exist. The California Air Resources Board (CARB) has identified backup power options that minimize community-level air pollutant emissions exposure. For more information, see CARB’s website.
