Proposed EPA standards would help bring relief to residents of fossil fuel development zones
FRISCO — The mythology of the American West includes standard notions of pristine vistas and clean air, but the reality is far different. Some parts of the region have a dirty little secret — air quality that, at times, is worse than places like L.A.
And for now, the problem is getting worse. Expanded drilling on public lands is resulting in emissions of more volatile organic compounds that form the chemical basis for ozone. Global warming won’t help either. By mid-century, ozone pollution will become much more widespread as temperatures rise, potentially leading to widespread plant damage, according to one recent study.
Proposed new EPA ozone standards could help, but only if there’s an active year-round monitoring regime in the region, a coalition of environmental groups said in their formal public comments on the proposed new standards. Continue reading

‘Air pollution across much of the globe is significantly underestimated because no one is tracking open-fire burning of trash’
FRISCO — As much as 1 billion metric tons of waste, including discarded plastics and electronics, is burned each year in unregulated fires, according to atmospheric scientists who set out last year to assess the impacts of trash burning.
The real amount of garbage that’s simply burned in the open probably far exceeds any official government estimates, the researchers said, adding that the practice exposes people to toxic fumes and adds to air pollution woes, especially in developing countries.
The estimate tonnage is about 41 percent of the total annual global waste stream, the study found, providing estimates, on a country-by-country basis, of pollutants such as particulates, carbon monoxide, and mercury that are emitted by the fires. Continue reading

New standards eyed to protect public health
FRISCO — The public will have a chance to weigh in on a proposed EPA rule to cut smog at three public hearings set for late January and early February.
In November, the agency unveiled its proposal to lower the standard from 75 parts per billion to as low as 60 ppb. 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 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.

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

Study shows how cutting carbon pollution pays huge dvidends by reducing health care costs.
‘Carbon-reduction policies significantly improve air quality’
FRISCO — Adopting a carbon cap-and-trade program would easily pay for itself — and then some — by reducing health care costs associated with treating asthma and other medical conditions resulting from air pollution, MIT researchers said in a detailed study that looked at the comparative cost and benefits of three potential climate policies.
Policies aimed at cutting carbon emissions from sources like power plants and vehicles, also lead to reductions in other harmful types of air pollution, the scientists said, publishing their findings last month in Nature Climate Change.
Overall, the study found that savings on health care spending and other costs related to illness can be big — in some cases, more than 10 times the cost of policy implementation. Continue reading
