Conservation groups say new road will hammer wetlands, tundra and wildlife
FRISCO — A new Bureau of Land Management plan for fossil fuel exploitation in Alaska has spurred criticism from environment groups, who say that a road included in the proposal will permanently damage the Western Arctic’s sensitive wetlands and tundra, with impacts to wildlife and subsistence values.
The BLM plan covers the Greater Mooses Tooth Unit 1 project in the 23 million acre National Petroleum Reserve-Alaska, also known as the Western Arctic Reserve, more than half of which is potentially open to oil and gas leasing. Conservation advocates are calling for more careful study of drilling impacts to ensure that the wildlife, subsistence and wilderness character of our nation’s largest parcel of public land are balanced with energy development.

A NASA satellite view shows oil from the Deepwater Horizon disaster spreading across the surface of the Gulf of Mexico.
“Oily particles were raining down around these deep sea corals …’
FRISCO — More than four years after the disastrous failure of BP’s Deepwater Horizon drilling rig sent about 5 million barrels of oil spewing into the Gulf of Mexico, a team of scientists said they’ve found a 1,250-square mile fallout zone, where some of the oil settled to the sea floor in a thin layer.
The researchers, from the University of California, Santa Barbara, the Woods Hole Oceanographic Institution and the University of California, Irvine sampled 534 locations during 12 expeditions in Gulf and collected more than 3,000 samples, finding that the oil is concentrated in the top half-inch of the sea floor.

New database to help assess impacts of planned dams
FRISCO — An emergent global hydropower boom will help meet the demand for low-carbon energy, but also poses environmental risks, according to experts compiling a new data base on global hydropower.
The boom is expected to double production of hydropower, but could also reduce the number of our last remaining large free-flowing rivers by about 20 percent and pose a serious threat to freshwater biodiversity.
A new database has been developed to support decision making on sustainable modes of electricity production. An unprecedented number of dams for electricity production is currently under construction or planned worldwide, mainly in developing countries and emerging economies in South America, Southeast Asia and Africa, that also hold some of the world’s most important sites for freshwater biodiversity.

Feds finalizing oil and gas development plan for 100,000 acres of public land
FRISCO — If it sometimes feels like fracking is closing in wherever you look, it’s because it is. One of the latest arenas for fossil fuel exploitation is on the Pawnee National Grasslands, in northeastern Colorado, described by the U.S. Forest Service as the country’s last remaining shortgrass prairie. Continue reading

Signs of oil and gas development are visible on a landscape level from 35,000 feet in the air.
Stable tracers can help pinpoint ground and surface water contamination
FRISCO — There’s more and more evidence that fracking wastewater can — and sometimes does — pollute ground and surface water, but it’s not always easy to trace the pollution, especially since drillers often keep secret their fracking fluid recipes.
But after field tests at a spill site in West Virginia and downstream from an oil and gas brine wastewater treatment plant in Pennsylvania, scientists say they can reliably identify hydraulic fracturing flowback fluids that have been spilled or released into the environment by using stable boron and lithium tracers that distinctive chemical fingerprints.

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

‘It is essential to identify where whales, dolphins and other species occur to help avoid adverse impacts and to continue to monitor their response to the construction and operation of wind turbines’
Offshore wind turbines could provide most of the power for North American cities.
FRISCO — Many of the conflicts between energy development and wildlife protection developed because there wasn’t enough upfront planning. Researchers with the University of Maryland say similar issues relating to offshore wind energy can be minimized with early monitoring.
“As the number and size of offshore wind developments increases, there is a growing need to consider the consequences and cumulative impacts of these activities on marine species,” said Helen Bailey, lead author and research assistant professor at the University of Maryland Center for Environmental Science’s Chesapeake Biological Laboratory.
“It is essential to identify where whales, dolphins and other species occur to help avoid adverse impacts and to continue to monitor their response to the construction and operation of wind turbines,” Bailey said. Continue reading
