Sublette County violates federal air quality standards, because of high levels of ozone, or smog. The ozone forms when emissions from oil and gas development mix together, under certain weather conditions. The Wyoming Department of Environmental Quality is responsible for fixing the problem, but there are a lot of unknowns about how ozone forms. Now, researchers at the University of Wyoming are trying to find some answers. We’re joined now by Rob Field. He’s an atmospheric scientist, and he’s been monitoring air quality in Sublette County for several years. to find some answers. We’re joined now by Rob Field.
