The Environmental Protection Agency has approved the Dallas–Fort Worth clean air plan for ozone, making the region the first in the nation to receive such an endorsement.

Under the plan, ozone-forming pollutants will be reduced by 88 tons per day, and officials expect air quality in the area to meet the federal ozone standard of 84 parts per billion by 2010.

The plan will improve air quality by more than 55 percent over 1999 levels, which, in combination with previous plans, will result in a total of 409 tons per day of ozone pollution reduction.
