Indiana gets another decade to meet 2008 ozone air quality standards

US environmental regulators are proposing to approve Indiana's plan to maintain 2008 ozone air quality standards for another ten years. This means the state's commitments to control ozone pollution in the Cincinnati area will become federally enforceable.

States must regularly prove they are meeting air quality standards set by federal law. This approval means Indiana has satisfied its legal obligation for the 2008 ozone standard for another decade. It locks in the current level of pollution control for the Cincinnati region, delaying any need for stricter measures.
