COLUMBIA, S.C. (AP) – State environmental officials are going to start issuing regular forecasts for ground-level ozone.

The Department of Health and Environmental Control will begin releasing the figure on a daily basis, starting Tuesday.

DHEC air quality chief Myra Reece says ozone is South Carolina’s most widespread air-quality concern during the warmer months. She says high ozone concentrations generally happen on hot sunny days when the air is stagnant.

Vehicles and lawn equipment contribute to more than half of the state’s ozone levels.

Reece says people can help make air cleaner and healthier by carpooling, driving less and using outdoor equipment in the evenings.
