Wyoming’s “core area” designation will not include critical winter range inside a proposed gas field, but a team will recommend special winter stipulations there.
Upper Green River Basin
Emissions from wastewater recycling at oil and gas drilling sites likely contributed to a string of high-ozone events in the winter of 2011 in Wyoming's Upper Green River Basin, according to a study released this week.
Wyoming’s Air Quality Advisory Board hears conflicting views on Wyoming standards as feds move further to reduce ozone.
Researchers learned that wintertime ozone production in the Uintah Basin occurs at lower concentrations of nitrogen oxides (NO) and much larger volatile organic compound (VOC) concentrations compared to summertime zone production in most urban areas.
U.S. EPA has determined that southwest Wyoming's Upper Green River Basin no longer meets federal ground-level ozone pollution standards, a conclusion that could significantly affect two of the nation's largest oil and natural gas fields.
