FRISCO — Environmental advocates and the EPA are facing off in a federal appeals court in Washington, D.C. today over air quality in Utah’s remote Uinta Basin, where ozone levels often exceed standards set to protect human health.

In a weird twist to the case, the fossil fuel industry is claiming that its own air pollution data is of poor quality and unreliable, and shouldn’t be used by the EPA to designate the Uinta Basin as a nonattainment area, despite the fact that the area regularly sees some of the highest ozone pollution levels in the country.

At issue in the oral arguments is the EPA’s refusal to designate the Uinta Basin as a nonattainment area despite monitoring showing serious air quality degradation in northeastern Utah. The EPA’s decision to designate the area as unclassifiable is a clear violation of the Clean Air Act, according to WildEarth Guardians, one of the groups involved in the case. Continue reading

Fossil fuel drilling fingered in Uinta Basin ozone formation

Better pollution control technology needed to cut VOC emissions

FRISCO — Ongoing studies of winter ozone formation in the Uinta Basin shows the need for better pollution control technology on oil and gas drilling rigs and other equipment used for fossil fuel development.

An emissions inventory developed for the study found that oil and gas operations are responsible for 98-99 percent of the volatile organic compounds (VOCs), and for 57-61 percent of the nitrogen oxide emissions. VOCs and nitrogen compounds are the key ingredients for ozone-laced smog, which has been clearly identified as a human health threat. Continue reading
