It's getting warmer in St. Louis and that means the issue of the region's air quality returns to the forefront.

Historically, the area has had pretty poor ozone levels. (Ozone is the main ingredient of urban smog that can be a significant health hazard, particularly for children with asthma.) Susannah Fuchs with the American Lung Association says the region’s air quality has gotten better but it still needs work.

The U.S. Environmental Protection Agency has proposed the first-ever national standards for air pollution from power plants.

The new rules would require many power plants to install technologies to control mercury, arsenic and other toxic air pollutants.

Environment Missouri's Ted Mathys says the new standards would help protect the health of Missourians.
