The state air resources board is required to expand its incident air monitoring program to provide support for a regional network of air quality incident response centers. These centers will be operated by air districts and will facilitate emergency air monitoring response at the local and regional level. The state board must coordinate and develop operational plans with the relevant air districts before establishing an air quality incident response center within an air district. Funding for these centers may be used for planning, creating, equipping, and maintaining them. If the commission on state mandates determines that the bill contains costs mandated by the state, reimbursement for those costs will be made pursuant to the state's statutory provisions.

CALIFORNIA LEGISLATURE— 2025–2026 REGULAR SESSION

Assembly Bill

No. 1106

Introduced by Assembly Member Michelle Rodriguez
(Principal coauthor: Senator Allen)

February 20, 2025

An act to ~~amend Section 39602.5~~ add Chapter 9 (commencing with Section 39950) to Part 2 of Division 26 of the Health and Safety Code, relating to ~~vehicular~~ air pollution.

LEGISLATIVE COUNSEL'S DIGEST

AB 1106, as amended, Michelle Rodriguez. ~~Vehicular air pollution:~~ State Air Resources Board: ~~regulations.~~ regional air quality incident response program.

Existing law generally designates the State Air Resources Board as the state agency with the primary responsibility for the control of vehicular air pollution, and air pollution control districts and air quality management districts with the primary responsibility for the control of air pollution from all sources other than vehicular sources. Existing law requires the state board to inventory sources of air pollution within the air basins of the state, determine the kinds and quantity of air pollutants, and monitor air pollutants in cooperation with districts and other agencies.
This bill would require the state board to expand its incident air monitoring program, subject to an appropriation by the Legislature for those purposes, to provide support for a regional network of air quality incident response centers operated by air districts, including at least one located in the South Coast Air Quality Management District, in order to facilitate emergency air monitoring response at the local and regional level. Prior to the state board establishing an air quality incident response center within an air district, the bill would require the state board to coordinate and develop operational plans for the air quality incident response centers with the relevant air districts. The bill would provide that funding made available to the state board for purposes of these provisions may be used for various purposes, including program funding to plan, create, equip, and maintain air quality incident response centers.
To the extent that the bill would expand the duties of an air district, the bill would impose a state-mandated local program.
The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.
This bill would provide that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above.
Existing law requires the State Air Resources Board to adopt rules and regulations relating to vehicular emissions standards, as specified, that will achieve the ambient air quality standards required by federal law in conjunction with other measures adopted by the state board, air pollution control and air quality management districts, and the United States Environmental Protection Agency. Existing law requires the state board to adopt and enforce rules and regulations that anticipate the development of new technologies or the improvement of existing technologies if necessary to carry out its duty.
~~This bill would make a nonsubstantive change to this provision.~~

Vote: MAJORITY Appropriation: NO Fiscal Committee: NOYES Local Program: NOYES
