California Air Resources Board

Summary

Would have updated the statewide refinery-related fence-line and community air monitoring program established by AB 1647 (Muratsuchi, Chapter 589, Statutes of 2017). The bill would have established statewide standards for the air monitoring program, including monitoring system capabilities, pollutants requiring monitoring, air quality control and assurance plans, third party audits, and data reporting. The bill also would have extended the air monitoring program deadline from January 1, 2020, to January 1, 2028, for updating or installing new air monitoring systems required by the bill. The bill would also have specified the type of refineries that are subject to the program, including biofuel refineries.

Governor’s Veto Message

To the Members of the California State Senate:

I am returning Senate Bill 674 without my signature.

This bill would make several changes to the refinery fence-line air monitoring program, including expanding the program to include monitoring for biofuel refineries and additional pollutants, applying the program to contiguous or adjacent refinery-related facilities, increasing the standards for data quality, and providing new processes for notifying local communities.

California has some of the most stringent refinery air monitoring and pollution standards in the world. These standards have been developed and implemented by the state's local air quality management districts, and each of these districts possess the authority and technical expertise to update, expand and modify these standards according to the best available science.

While I share the author's desire to protect communities from air pollution, local air quality management districts are already carrying out the necessary action to do just that. Additionally, because this bill mandates these districts to implement highly prescriptive measures, it might be found to require state reimbursement of implementation costs at a time when we just recently closed a $44.9 billion shortfall for the 2024-25 fiscal year. There is no state funding identified or available in the state budget to support these efforts.

For these reasons, I cannot sign this bill.

Sincerely,

Gavin Newsom
