Oklahoma earthquake spike definitively linked with wastewater injection.
More monitoring and mitigation needed, scientists say
By Summit Voice
FRISCO — Just a small number of wastewater injection wells associated with fossil fuel exploitation can lead to a dramatic increase in earthquakes, U.S. Geological Survey scientists concluded in a new study focusing on the spike in Oklahoma earthquakes since 2009. Wastewater injection can trigger earthquakes up to 20 miles away, the researchers found, far beyond the three-mile radius commonly used as a measure for diagnosing induced earthquakes.
The dramatic increase in earthquakes in central Oklahoma since 2009 is likely attributable to subsurface wastewater injection at just a handful of disposal wells. Oklahoma earthquakes constitute nearly half of all central and eastern U.S. seismicity from 2008 to 2013, many occurring in areas of high-rate water disposal, said Cornell University geophysics professor Katie Keranen, who led the study.

Oklahoma earthquakes are on the increase.
Spike in tremors linked with injection of wastewater from fracking
By Summit Voice
FRISCO — Federal and state geologists say there’s an increased risk of a strong earthquake in Oklahoma after the overall rate of quakes increased by about 50 percent since late 2013.
After statistically analyzing the increased rate of earthquakes, the scientists said they’re fairly certain it’s not just natural variability — deep injection of waste water from fossil fuel exploitation is seen as a likely cause. Continue reading

More coal mining equals more ozone

FRISCO — Federal officials may have failed to adequately assess the environmental impacts of more coal mining in northwestern Colorado, according a conservation group that’s suing the Bureau of Land Management over an expansion permit for the Deserado coal mine, located in Rio Blanco County in northwestern Colorado directly south of Dinosaur National Monument.
The mine fuels the 500-megawatt Bonanza power plant, located 30 miles west in Uintah County, Utah. The mine and the power plant are connecte by a dedicated electric train.
According to WildEarth Guardians, the BLM failed to address air quality impacts from fossil fuel combustion from the Bonanza facility. The group said regional air quality monitoring shows continued violations of ozone. According to the lawsuit, the mine expansion would mean that the Bonanza power plant would continue to operate for another 16 percent years — too long in the context of climate change.

BLM lease sales based on flawed, incomplete analysis, environmentalists say
FRISCO — Conservation advocates are formally challenging a Bureau of Land Management proposal to lease lands for natural gas exploitation in north-central Nevada based in part on the federal agency’s failure to require an in-depth environmental study.
The lease sale could open up more than 174,000 acres around Tonopah and Austin on 102 lease parcels. In filing the protest, the Center for Biological Diversity spelled out a laundry list of concerns about the BLM’s process, highlighting the fact that the agency’s evaluation of the proposed lease doesn’t come close to addressing key environmental concerns. Instead of developing more fossil fuel resources, the emphasis in Nevada should be on renewable energy resources like wind, solar and geothermal. Continue reading

Cancer-causing chemicals escaping from fossil fuel facilities by the ton
FRISCO — Colorado communities looking to regulate the toxic and dangerous impacts of oil and gas drilling may not get any help from Gov. John Hickenlooper, but they may get some backup from a huge coalition of environmental groups that have petitioned the EPA for limits on oil and gas wells and associated equipment in population centers around the U.S.
As thousands of new wells are drilled across the U.S. every day, some studies suggest that at least 100,000 tons per year of hazardous air pollution from oil and gas well sites — including benzene, formaldehyde, and naphthalene — are escaping into the atmosphere. These pollutants have been linked to respiratory and neurological problems, birth defects, and cancer. Continue reading

Findings show value of long-term post-spill monitoring
FRISCO — Methane-munching microbes in the Gulf of Mexico may have been overwhelmed by the sheer volume of gas released during the 84-day Deepwater Horizon oil disaster in 2010.
“Most of the gas injected into the Gulf was methane, a potent greenhouse gas that contributes to global climate change, so we were naturally concerned that this potent greenhouse gas could escape into the atmosphere,” said University of Georgia researcher Samantha Joye.” Many assumed that methane-oxidizing microbes would simply consume the methane efficiently, but our data suggests that this isn’t what happened.” Continue reading

New research show true magnitude of fossil fuel pollution along Front Range
FRISCO — Heat-trapping greenhouse gases and other air pollutants are leaking from Colorado oil and gas operations at a far higher rate than previously estimated.
Two days of aerial surveys showed methane leaking at three times the rate predicted by inventory estimates, and seven times as much benzene, a cancer-causing air toxic.Emissions of other chemicals that contribute to summertime ozone pollution were about twice as high as estimates, according to the new paper, accepted for publication in the American Geophysical Union’s Journal of Geophysical Research: Atmospheres.

Oil-probing technology could harm marine mammals, affect fisheries

FRISCO — Tourism and fishing-dependent communities along the East Coast of the U.S. are banding together to voice concerns about seismic airgun testing. According to Oceana, an ocean conservation group, 110 local elected officials and 155 conservation and animal welfare organizations all say the use of airguns to conduct these seismic tests threatens fish populations and profitable fisheries.
Six coastal towns have also passed local resolutions opposing the use of airguns. (Cocoa Beach, FL, Carolina Beach, NC, Caswell Beach, NC, Nags Head, NC, Bradley Beach, NJ and Red Bank, NJ). The loud and constant undersea thumping may decrease the catch rates of certain fisheries, potentially threatening a billion-dollar industry that supports thousands of jobs.
At issue is the use of loud acoustic devices that help energy companies probe for oil beneath the seafloor. Federal officials recently adopted a final proposal that would allow the use of this controversial technology in an area twice the size of California, stretching from Delaware to Florida.

BLM taking input during scoping phase of environmental study
By Bob Berwyn
FRISCO — Lynx, elk, owls and other high country forest critters in western Colorado will get at least a temporary reprieve from potential oil and gas drilling, as the federal Bureau of Land Management announced last week that it will do an in-depth environmental study for 65 existing oil and gas leases on 80,000 acres of public lands managed by the White River National Forest.
The leases are spread roughly west to east along biologically important mid-elevation lands between Carbondale and DeBeque and overlap designated roadless areas. Conservation advocates have long argued that the sale of the leases was inconsistent with efforts to protect wildlife, water quality and other high-value natural resources. Continue reading

The conical drilling unit Kulluk sits aground on the southeast shore of Sitkalidak Island about 40 miles southwest of Kodiak City, Alaska, in 40 mph winds and 20-foot seas Tuesday, Jan. 1, 2013. The Kulluk grounded following many efforts by tug and Coast Guard crews to tow the vessel to a safe harbor when it was beset by winter storm weather during a tow from Dutch Harbor, Alaska, to Everett, Wash.

Investigators delve into potential legal violations
By Bob Berwyn
FRISCO —A U.S. Coast Guard report says Shell Oil didn’t acknowledge or adequately prepare for Arctic Ocean conditions before the company’s Kulluk drilling rig broke away from its towing vessel and ultimately ran aground on an Alaskan Island on the last day of 2012.
“Inadequate assessment and management of risk” was the key factor in the accident, Coast Guard investigators concluded, calling on Shell and its partners to change their company culture to avoid complacency.
