ST. LOUIS — The St. Louis and Kansas City areas, along with part of southeast Missouri, have violated air quality standards and might be forced to impose new restrictions.

The Missouri Department of Natural Resources on Thursday said ozone levels in St. Louis, Kansas City and Ste. Genevieve County were above the eight-hour standard at some points during the April 1 to Oct. 31 ozone season.

The violations typically would require additional restrictions to cut pollutants created by trucks, cars, power plants and other businesses.

St. Louis and Kansas City already are under ozone control measures because of air quality.

The Environmental Protection Agency is reviewing the ozone standards set last year and might make them more stringent. That process might take two years.
