Air Pollution and the Future

While we have made significant achievements in improving air quality over the past 20 years, air pollution from automobiles remains a challenge. The number of registered vehicles in Ohio has increased 125 percent since 1970. This increased number of vehicles overshadows the benefits of today's cleaner-burning vehicles. The Ohio E-Check program is essential to identifying those vehicles in need of emission repair so that they can be made to run cleaner and more efficiently.

On April 15, 2004, U.S. EPA announced that 33 Ohio counties were out of attainment for the eight-hour ozone standard. In order for Ohio to meet the eight-hour standard, additional air pollution control measures may be necessary in these counties.
