CHICAGO (June 14, 2007) - U.S. Environmental Protection Agency Region 5 announced today it is proposing to approve a request by the state of Ohio to redesignate Clark, Greene, Miami and Montgomery counties in the Dayton-Springfield area to attainment of the national health-based eight-hour outdoor air quality standard for ozone (smog).

EPA said three years of complete, quality-assured, outdoor air monitoring data for 2004, 2005 and 2006 show the area meets the standard.

The Agency also proposed to approve the state plan to continue to meet the eight-hour health-based ozone standard through 2018 and to approve motor vehicle emissions budgets included in the plan.

The action will soon be published in the Federal Register. The public will then have 30 days to comment on the proposed action. Comments may be entered at www.regulation.gov. Refer to docket ID No. EPA-R05-OAR-2006-0956 and follow the online instructions for submitting comments. Comments may also be sent by e-mail to [email protected], or faxed to 312-886-5824.

Ground-level ozone is commonly referred to as smog. Smog is formed when a mixture of pollutants react on warm, sunny days. The pollutants are released from cars, factories and a wide variety of other sources. Smog can cause respiratory problems, including coughing, wheezing, shortness of breath and chest pain.
