AB1777 - Air pollution: indirect sources.

CALIFORNIA LEGISLATURE— 2025–2026 REGULAR SESSION Assembly Bill No. 1777 Introduced by Assembly Member Garcia February 09, 2026 An act to amend Section 39602.5 of the Health and Safety Code, relating to air pollution. LEGISLATIVE COUNSEL'S DIGEST AB 1777, as introduced, Garcia. Air pollution: indirect sources. 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 authorizes air districts to adopt and implement regulations to reduce or mitigate emissions from indirect sources of air pollution. Existing law requires the state 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 districts, and the United States Environmental Protection Agency. This bill would authorize the state board, if necessary to carry out that duty to achieve those ambient air quality standards, to adopt regulations to reduce or mitigate emissions from indirect sources of pollution. Existing law makes any violation of a rule or regulation of the state board relating to nonvehicular air pollution control a misdemeanor. Because a violation of these regulations of the state board with respect to nonvehicular sources subject to those regulations would be a crime, this 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 no reimbursement is required by this act for a specified reason. Digest Key Vote: MAJORITY Appropriation: NO Fiscal Committee: YES Local Program: YES Bill Text The people of the State of California do enact as follows: SECTION 1. Section 39602.5 of the Health and Safety Code is amended to read: 39602.5. (a) The state board shall adopt rules and regulations pursuant to Section 43013 that, in conjunction with other measures adopted by the state board, the districts, and the United States Environmental Protection Agency, will achieve ambient air quality standards required by the federal Clean Air Act (42 U.S.C. Sec. 7401 et seq.) in all areas of the state by the applicable attainment date, and to maintain these standards thereafter. The state board shall adopt these measures if they are necessary, technologically feasible, and cost effective, consistent with Section 43013. (b) If necessary to carry out its duties under this section, the state board shall adopt and enforce rules and regulations that anticipate the development of new technologies or the improvement of existing technologies. The rules and regulations shall require standards that the state board finds and determines can likely be achieved by the compliance date set forth in the rule. (c) (1) If necessary to carry out its duties under this section, the state board may adopt regulations to reduce or mitigate emissions from indirect sources of pollution. (2) The Legislature finds and declares that paragraph (1) is declaratory of, and does not constitute a change in, existing law. (d) For purposes of this section, “indirect source” has the same meaning as set forth in Section 7410(a)(5)(C) of Title 42 of the United States Code. SEC. 2. No reimbursement is required by this act pursuant to Section 6 of Article XIII B of the California Constitution because the only costs that may be incurred by a local agency or school district will be incurred because this act creates a new crime or infraction, eliminates a crime or infraction, or changes the penalty for a crime or infraction, within the meaning of Section 17556 of the Government Code, or changes the definition of a crime within the meaning of Section 6 of Article XIII B of the California Constitution.
