The bill introduces a new section to the Air Quality Control Act that prohibits the construction of new oil and gas sources in counties where ozone concentrations exceed the primary national ambient air quality standards. This prohibition will take effect on July 1, 2025, and will be enforced by the department and local agencies. The determination of whether a county exceeds these standards will be made by the environmental improvement board or the local agency based on emissions from existing sources.

This legislation aims to address environmental concerns related to air quality and ozone levels, aligning state regulations with federal standards set forth in the Clean Air Act. By restricting new oil and gas construction in areas with high ozone levels, the bill seeks to mitigate further contributions to air pollution and protect public health.
