If enacted, this bill would amend current statutes related to air quality in Arizona by allowing the Attorney General (AG) to file lawsuits against the U.S. Environmental Protection Agency (EPA) if the EPA fails to approve a demonstration that shows any area of Arizona could meet national air quality standards but for emissions from outside the U.S. Additionally, the bill would require the Director of the Arizona Department of Environmental Quality (ADEQ) to consider the best interests of taxpayers and various causal factors affecting air quality, including emissions from other domestic states and the effects of solar radiation, while explicitly prohibiting the consideration of emissions from outside U.S. borders.

The bill also includes a statement of legislative findings that highlights the impact of external emissions on Arizona's air quality, particularly in the Maricopa nonattainment area, and asserts that the EPA's current interpretation of federal law is contrary to its intended application. Furthermore, it makes technical and conforming changes to existing statutes, ensuring that the state implementation plan remains effective while aligning with federal regulations. Overall, the proposed changes aim to enhance Arizona's ability to address air quality issues stemming from external sources.
