Wyoming’s southwestern region was found to have an unsafe level of smog-causing ozone for the first time, a designation the U.S. Environmental Protection Agency linked to a boom in oil and gas drilling in the state.
The EPA included the Upper Green River Basin in its list of areas nationwide exceeding a federal ozone limit. Until today, Wyoming was the only state where all counties had met the federal ozone limit.
