Maricopa County fails to show it can control air pollution from gasoline

US environmental regulators are rejecting Maricopa County's plan to control air pollution from gasoline and other liquid fuels. This means the county must now create a new plan to meet federal clean air standards.

Local governments are responsible for showing how they will meet federal air quality standards. When a county's plan is rejected, it signals that their current approach is not working. This forces them to rethink how they regulate emissions from common sources like gas stations and industrial loading facilities.
