CA SB732

Requires air districts that adopt new rules on emergency backup generators after January 1, 2026, to include exemptions allowing critical facilities to exceed runtime and testing/maintenance limits during deenergization events or other power losses

Defines critical facilities as hospitals, police stations, fire stations, emergency operations centers, water and wastewater facilities, incident command posts, and communication systems supporting essential public services

Defines emergency backup generators as internal combustion engines over 50 brake horsepower or gas turbines over 2,975,000 BTU per hour that operate no more than 200 hours annually and only during emergencies or routine testing

Critical facilities using these exemptions must demonstrate they are taking steps toward cleaner backup power technologies, such as contracting to purchase compliant technology, issuing requests for proposals, or applying for funding to acquire it

Addresses the need for reliable backup power at water and wastewater facilities during public safety power shutoffs initiated by utilities to prevent wildfires
