Earlier this year, the ozone level in Wyoming’s once pristine Upper Green River Basin spiked beyond Los Angeles’ worst smog day. Thirteen high-ozone events this past winter from oil and gas activities in the region resulted in 10 state-issued warnings to remain indoors.
Yet Wyoming’s governor and the oil and gas industry can’t guarantee they will cut emissions in the Upper Green River Basin far enough to result in zero wintertime ozone spikes.
