Area Designations for 2008 Ground-level Ozone Standards
2008 Ground-level Ozone Standards -
Region 10 Final Designations, April 2012
EPA is implementing the 2008 ozone standards as required by the Clean Air Act. Meeting these standards will provide important public and environmental health benefits. EPA has worked closely with states and tribes to identify areas in the country that meet the standards and those that need to take steps to reduce ozone pollution.
EPAs final designations are based on air quality monitoring data, recommendations submitted by the states and tribes, and other technical information. EPA will work closely with states and tribes to implement the standards using a common sense approach that improves air quality, maximizes flexibilities and minimizes burden on state and local governments.
