AB 1857

Bill Subjects

State Air Resources Board Air Quality Regulation Valleys

Abstract

Existing law imposes various limitations on emissions of air contaminants for the control of air pollution from vehicular and nonvehicular 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 and air quality management districts with the primary responsibility for the control of air pollution from all sources other than vehicular sources. This bill would require the state board to adopt regulations to improve air quality in population centers located in valleys and would require each local air district to implement those regulations with regard to stationary sources located within its jurisdiction. The bill would make those requirements inoperative on January 1, 2029, and would require the state board, on or before January 1, 2030, to submit a report to the Legislature and specified committees of the Legislature describing any air quality improvements resulting from those regulations. By adding to the duties of local air districts, 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, 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.
