Well density seen as key factor in decline of birds in Wyoming
Limiting the density of new oil and gas drilling rigs in Wyoming may not be enough to stem the decline of greater sage-grouse, according to scientists tracking populations of the imperiled bird.
Berween 1984 and 2008, populations declined by 2.5 percent annually, and the drop is clearly linked with oil and gas development, the new study from the USGS and Colorado State University found. The researchers used annual counts of males at breeding sites for their estimates, comparing those tallies to the the density of oil and gas wells and the area of disturbance associated with these wells.

Conservation activists won protection for the plants in 2013, when the U.S. Fish and Wildlife Service determined that 91 percent of Graham’s beardtongue populations and 100 percent of White River beardtongues were threatened by the impacts of oil and gas development. But a year later, the agency reversed course, claiming that a voluntary conservation agreement would mitigate those threats. Continue reading “Legal wrangling continues over rare oil patch plants”→
Oil and gas exploration would have widespread effects on marine mammals
Conservation advocates have long been saying that blasting the Gulf of Mexico with seismic airguns to find more oil and gas beneath the seafloor would result in unacceptable harm to marine mammals and other marine life, and a new draft environmental study by the Bureau of Ocean Energy Management seems to confirm those concerns.
The study was completed under the terms of a court-ordered settlement of a lawsuit brought by environmental groups. It shows that the blasting would have widespread impacts on marine life, including injuries to endangered sperm whales and Bryde’s whales. The draft report outlines possible mitigation measures, including closure areas where seismic blasting would be banned, and reductions in the amount of activity permissible each year.

Findings can help oil and gas operators minimize seismic risks
For nine months, oil and gas companies pumped 250,000 barrels of industrial wastewater deep underground in the fossil fuel sacrifice zone around Greeley, Colorado — and then, the Earth burped.
On the last day of May, 2014, the wastewater triggered a magnitude 3.2 earthquake that for some area residents felt like a truck hitting their house. The quake was the first in the area in about 40 years, fitting a regional pattern of earthquakes linked with fracking.
Now, a new study by scientists with the U.S. Geological Survey and the University of Colorado shows it may be possible to lessen the risk of frack-quakes by controlling the amount of wastewater being pumped into the ground, and by carefully monitoring seismic activity in fossil fuel development areas.

Research to help shape efforts to reduce dangerous air pollution
By Bob Berwyn
Emissions from oil and gas production along the Colorado Front Range are a significant, measurable part of the region’s chronic summer ozone problem, scientists concluded after taking a close look at air pollution during an extensive research project in the summer of 2014.
Ozone levels in the area often spike above 70 parts per billion, a level deemed by the EPA to be dangerous to human health and to the environment, causing respiratory problems and damage to plants. About 17 ppb of that ozone are produced locally; about 3 ppb come from oil and gas industry emissions, according to a new study, published in the Journal of Geophysical Research.
Fossil fuel protestors targeted by undercover investigations
The threat of international terrorism apparently is not keeping federal agents so busy that they don’t have time to investigate the largely peaceful community of climate activists who are advocating for a rapid shift to a carbon-free energy economy.
In recent months, federal and local law enforcement agencies have cooperated with fossil fuel companies to spy on groups like 350.org and the Break Free movement, as shown by a series of documents obtained by The Intercept. Those records show that agents went underground to monitor the groups activities and training sessions. Of course, such domestic intelligence operations aren’t new — paranoid government agencies have a long history of tracking activists going back at least to Dr. Martin Luther King.

Report says more monitoring of wildlife needed on offshore oil drilling rigs
It only takes exposure to a teaspoon full of oil to kill some seabirds, but oil drillers off the coast of Canada are failing to adequately monitor small, persistent spills that can lead to chronic pollution and population-level impacts, according to a new study by scientists with York University.
The research published in the international journal, Marine Pollution Bulletin, looked at how offshore oil operators monitored and responded to small spills (less than 1,000 litres) for three production projects off the coast of Newfoundland and Labrador. It came after authorities failed to respond to three high-profile environmental assessments by Environment Canada that requested impacts on seabirds be monitored following small spills.
