FRISCO — A $167,000 grant has helped Rocky Mountain National Park boost environmental efforts.
The 2013 grant from the U.S. Department of Energy’s Clean Cities National Parks Initiative supports alternative transportation projects aimed at reducing greenhouse gas emissions and educating park visitors about the environmental benefits of reducing our dependence on petroleum.
Through the partnership, the park purchased two electric sedans and one hybrid pickup truck, installed two electric charging stations, launched an idle reduction campaign and enhanced the parks education and outreach efforts toward reducing greenhouse gas emissions and enhancing sustainable operations.

La Niña weather pattern found to contribute to spikes in western ozone levels
FRISCO — Spring ozone formation in parts of the western U.S. appear to be linked with the hemispheric La Niña weather pattern, when the path of the jet stream forces high altitude ozone down to ground level.
After discovering the link, a team of researchers say their findings may help forecast harmful ozone episodes well in advance, which could have implications for attaining the national ozone standard. Continue reading

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
