Better pollution control technology needed to cut VOC emissions
Monitoring sites in the Uinta Basin.
By Summit Voice
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

Study finds the insect epidemic may increase ambient levels of VOCs
Bark beetles may increase air pollution, as beetle-killed trees release up to 20 times more VOCs into the atmosphere.
By Bob Berwyn
SUMMIT COUNTY — As if millions of acres of dead forests aren’t enough, the waves of bark beetles spreading across the West may also be contributing to increased air pollution in the region.
A new study shows the insects can make trees release up to 20 times more of certain organic substances that foster haze and air pollution in forested areas. The gases, classified as volatile organic compounds — meant to be a defense against the beetles — are released from the beetles’ bore holes.
VOCs are known to contribute to smog and haze that obscures views of natural landscapes in U.S. national parks and other natural areas where tourists flock in summer. The haze may in turn harm human health, reduce visibility and affect climate. Continue reading
