State Air Resources Board: regulations: impact estimates: retail gasoline prices: public disclosure.

Assembly Member Macedo's proposal to enhance transparency in California's air quality regulations would require the State Air Resources Board (CARB) to publish retail gasoline price impact estimates before implementing new regulations affecting fuel suppliers. The legislation establishes a framework for CARB to work with the State Energy Resources Conservation and Development Commission in analyzing how proposed rules may influence consumer fuel costs.

Under the measure, CARB must release public estimates detailing the potential price effects of both new regulations and amendments to existing rules that impose costs on gasoline refiners, distributors, or retailers. These assessments would need to calculate the maximum possible price impact by assuming all regulatory compliance costs are passed through to consumers. The estimates would be made available on CARB's website and through other public channels.

The proposal adds these requirements while maintaining CARB's existing authority as California's lead agency for Clean Air Act implementation and air quality regulation. By mandating price impact analysis before rule adoption, the measure creates a new procedural step in CARB's regulatory process specifically focused on fuel cost transparency.
