New rule would more than pay for itself in health care savings
FRISCO — As more and more studies show the harmful health effects of smog, or ground-level ozone, the EPA wants to set new standards to help clean up the air.
Last week the agency unveiled its proposal to lower the standard from 75 parts per billion to as low as 60 ppb, pending completion of a review and comment period, including public hearings.
The Clean Air Act requires EPA to review the standards every five years by following a set of open, transparent steps and considering the advice of a panel of independent experts. EPA last updated these standards in 2008, setting them at 75 ppb. Continue reading

New study projects mid-century air quality under various global warming scenarios
FRISCO — Even with ongoing efforts to improve air quality, global warming could drive ozone levels high enough to cause widespread damage to plants by mid-century, according to a new study that focused on the U.S. but also considered global air quality.
“Modelling future air quality is very complex, because so many factors need to be taken into account at both a global and local scale,” said Dr. Val Martin, of the University of Sheffield’s Faculty of Engineering. Continue reading

EPA challenged on decision to designate polluted region as unclassifiable
By Bob Berwyn
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

Air quality worsening in rural areas affected by fracking
FRISCO — Dangerously high levels of winter ozone pollution in parts of Utah can be traced directly to chemicals released into the air by oil and gas exploration. The volatile organic compounds, common byproducts of fossil fuel exploitation, get trapped under atmospheric inversion layers and sunlight reflected by snow sparks the chemical process that forms the corrosive gas.
For example, in 2013, ozone in Ouray, Utah, exceeded the national air quality standards 49 times during the winter season. By contrast, in the densely populated, urban area of Riverside, California, the standards were exceeded about half that amount that same year, but during the summer. Continue reading

Snow may intensify the air quality impacts of energy development
By Bob Berwyn
FRISCO — A team of American and Canadian scientists want to unravel some of the secrets of winter ozone formation related to oil and gas drilling — and they need your help.
University of Washington atmospheric researcher Becky Alexander, who is leading the January research project in Utah’s Uintah Basin has launched a crowdfunding campaign to help finance the field work. The team wants to raise $12,ooo in the next three weeks via their project website at mycroriza.com.
“It’s a global outreach effort,” Alexander said, explaining that crowdfunding for scientific research is a new and growing movement. Grassroots funding helps eliminate some of the administrative overhead costs sometimes associated with traditional sources of money. Sometimes, as much as 50 to 60 percent of federal funding ends up going toward overhead, she explained. Continue reading

The BLM’s Colorado River Valley Field Office covers some of the most active oil and gas drilling territory in Colorado.
By Bob Berwyn
FRISCO — Acknowledging a gap in its analysis of Colorado western slope oil and gas drilling activities, the Bureau of Land Management this week agreed to take a much closer look at air pollution resulting from 34 projects covering a total of more than 1,300 proposed wells in the jurisdiction of the agency’s Silt-based Colorado River Valley Field Office.
More than 250 wells have already been drilled, and 54 more have been permitted, but any new permits will require additional analysis.
The settlement came after conservation groups filed a 2011 lawsuit to force the BLM to examine pollution from oil and gas drilling, acknowledged as one of the main sources of regional haze and ozone pollution in the Intermountain West. Continue reading

Wildfires, industrial sources contribute to ozone problems in the Eastern Sierra Nevada
By Summit Voice
SUMMIT COUNTY — Devils Postpile National Monument in the eastern Sierra Nevada is about as far as you can get from California’s industrial urban centers, yet air quality at the site has suffered in recent years as pollution blows in from other parts of the state, according to a new U.S. Forest Service-led study.
The monument, near the resort town of Mammoth Lakes, features one of the best examples of columnar basalt formations and is also a gateway to High Sierra wilderness areas bordering on Yosemite National Park.
Ozone precursors (nitrogen oxides and volatile organic compounds) from wildland fires, as well as ozone from the Bay Area and Central Valley resulted in exceedances of federal air quality standards, as well as state air quality standards during the 2007-2008 study period, at levels that pose a risk to sensitive individuals and indicate a need for long-term ozone monitoring.
