Atmospheric emissions of hormone-disrupting chemicals found to pollute rivers and streams.
Hormone-disrupting toxins in Missouri streams traced to factory emissions
FRISCO — Scientists say atmospheric releases of hormone-disrupting chemicals may be a big source of of pollution in streams and lakes. After studying water quality near industrial sites permitted to release toxic chemicals into the air, the researchers said they found unexpectedly high levels of BPA in water around those factories.
“This finding suggests that atmospheric BPA releases may contaminate local surface water, leading to greater exposure of humans or wildlife,” said Don Tillitt, adjunct professor of biological sciences at MU, and biochemistry and physiology branch chief with the U.S. Geological Survey’s Columbia Environmental Research Center.

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

Big coal-burning states stand to gain the most
FRISCO — Obama administration officials have said all along that, with cutting heat-trapping greenhouse gas emissions, the EPA’s proposed Clean Power Plan will lead to huge health benefits for states, potentially saving thousands of lives and millions of dollars in health care costs.
A new Harvard-led study confirms those claims after comparing three different scenarios for power plant carbon standards. Under the biggest cuts, the study projected the regs could prevent 3,500 premature deaths in the US every year, with a range of 780 to up to 6100. Continue reading

Five new solar-powered monitoring stations to be added this year
FRISCO — The EPA is bringing air quality data to the people with the installation of five new Village Green solar-powered air monitoring stations in different cities around the country. The monitoring instruments are fitted into park benches and will measure common air pollutants and weather conditions.
The project puts science into the hands of citizens, allowing them to access local air quality information from the benches through on-site displays and a mobile-friendly website. Continue reading

Settlement with EPA, state health department should cut emissions of smog- and cancer-causing toxic gases

FRISCO — For years, thousands of storage tanks owned and operated by Houston-based Noble Energy leaked toxic smog- and cancer-causing gases into the Colorado’s heavily fracked Front Range.
When when state and federal environmental inspectors confronted the company with evidence of the leaks, executives shrugged, and said their systems weren’t designed to handle the sudden oil and gas boom across the region. Continue reading

Global methane leaks totaled 3.5 trillion cubic feet in 2012
*More Summit Voice stories on methane
FRISCO — Reducing methane leakage from drilling sites, pipelines and storage tanks represents a huge low-cost opportunity in the battle to cut greenhouse gas emissions, according to a new report that says 3.5 trillion cubic feet of gas — worth about $30 billion — escaped from oil and gas sector operations in 2012.
The majority of oil and gas methane leakage comes from a handful of countries, with the top seven emitting countries responsible for over half of the global total in 2012. Despite the huge scale of the methane loss, very few have taken steps to regulate leakage from the oil and gas sector, or set specific goals to reduce emissions in the future. But the benefits of doing so would be considerable, according to the report.
