Description
About 250 barrels of oil spilled from a platform in the North Sea during the transfer of products to an oil tanker, Norwegian energy company Statoil said. Statoil said the oil spill was discovered during the loaded of oil from the Statfjord A platform in the North Sea to oil tanker Hilda Knutsen. The company said in its latest update on the spill that about 250 barrels in total were released into the North Sea. "Further assessment and investigations will uncover the scope and causes [of the spill] in more detail," the company said in a statement. Loading to Hilda Knutsen was halted, though operations at the Statfjord A platform were proceeding as normal. Statoil said the relevant authorities were notified, though there were no statements from the Norwegian Petroleum Safety Authority. In January last year, the company shut down operations at the Statfjord C platform after emergency systems detected an oil leak. More than 250 crewmembers were evacuated to lifeboats but returned to their living quarters later in the day. No injuries were reported. Statoil said the weather in the area at the time of the Stratfjord C incident was "harsh." Statoil said the region is producing an average 80,000 barrels of oil per day.

Public Emergency Declared Over Elevated Lead Levels In Flint's Water

It's not the water supply. It's the plumbing.

<span class='image-component__caption' itemprop="caption">In this Tuesday, Feb. 3, 2015 photo, Genetha Campbell carries free water being distributed at the Lincoln Park United Methodist Church in Flint, Mich, Since the financially struggling city broke away from the Detroit water system last year, residents have been unhappy with the smell, taste and appearance of water from the city’s river as they await the completion of a pipe to Lake Huron.

DETROIT (AP) -- A public health emergency has been declared in cash-strapped Flint after tests showed the Michigan city's water supply is causing elevated levels of lead in children and following months of complaints about the smell and taste.

Gov. Rick Snyder this week questioned the switch to the Flint River from the Detroit water system in 2014, a decision that was made as a cost-saving move while a new regional pipeline is built to Lake Huron.

And on Thursday, the Genesee County health department declared a public health emergency, recommending that people not drink the water unless it has been filtered and tested to rule out elevated levels of lead. More steps will be announced Friday.

The problem: Although the river water is treated, it is corrosive and releasing lead from old plumbing in thousands of homes.

A coalition of residents and national groups petitioned the U.S. Environmental Protection Agency to order the state to reconnect Flint to Detroit water.

Fracking fluids dumped into the ocean
Environmentalists are trying to convince the EPA to ban the dumping of fracking fluids, in federal waters off the California coast. The Center for Biological Diversity claims that at least a dozen off shore rigs in Southern California are dumping wastewater right into the Pacific. RT's Ramon Galindo has the story.

RT's Ramon Galindo talks about a recent legal petition by environmental groups in California calling for the Federal government to force an end to the practice of offshore fracking, and the dumping of hundreds of millions of gallons of fracking waste in the ocean every year.

Abby Martin calls out Exxon CEO Rex Tillerson for his blatant hypocrisy after filing a lawsuit against a fracking water tower being built near his property.

Los Angeles Becomes Largest City to Approve Fracking Moratorium


Fracking for oil and gas will not be happening in Los Angeles any time soon after City Council members unanimously voted to ban the practice within city limits today. The vote passes the motion to the City Attorney's office where it will be rewritten as a zoning ordinance before returning to City Council for a final vote.
L.A. is now the largest city in the U.S. to refuse the dangerous extraction process. Local bans have become an effective protective measure against fracking, and are in place in numerous jurisdictions worldwide including Vermont, Hawaii, areas of New York State, Quebec, and France among many others.
The Los Angeles ordinance prevents the use of fracking until effective governmental oversight and regulation is in place at the local, state and federal levels.
“I think we can all agree unregulated fracking is crazy,” said Councilman Paul Koretz, co-author of the motion.
California is in the midst of a devastating drought, raising concerns over access to fresh water supplies. Fracking uses approximately 5 million gallons of water per frack job.
Image from Gizmodo shows Folsom lake near Sacramento in July 2011 and again in January 2014.
According to the Center for Biological Diversity, there are still 9 Californian counties where fracking is in use, including Colusa, Glenn, Kern, Monterey, Sacramento, Santa Barbara, Sutter, Kings and Ventura.

Hmmmm Factor : Free pizza! Chevron issues controversial apology to town plagued by fracking explosion

Published time: February 19, 2014 00:53

With one person missing and presumed dead in an explosion at a natural gas well in a small Pennsylvania town, the company responsible is now under fire after apparently apologizing to the local community by handing out vouchers for free pizza.
It took five days for emergency crews to safely extinguish a fire that was set by an explosion that shook the small town of Bobtown, located in the far southwestern corner of the state. The blast gave off a loud hissing noise that could be heard from hundreds of yards away.
One resident told the Pittsburgh Post-Gazette that the explosion in a shale formation where Chevron Corp. has spent time fracking “sounded like a jet engine going five feet above your house.” John Kuis, 57, of nearby Dilliner said his dog started growling unusually at 6:45 a.m. on February 11 “then the house just sort of shock and there was a big loud bang.”
At least one employee who was working on the rig has not been found and is widely thought to have been killed – either in the initial explosion or during the five days the flames burned. Another worker was injured in the event.
Chevron has denied any knowledge of what caused the explosion. Company spokesman Ken Robertson told the local ABC affiliate that workers were preparing to run tubing, which is done when wells are being readied for production, and that “there is not enough fuel being emitted to sustain combustion, and with the cooling of the crane, the ignition source has been removed.”
The Philadelphia Daily News has since discovered that residents of Bobtown – a census-designated community of fewer than 1,000 people that revolves mostly around coal mining – have started receiving coupons for one free pizza and a two-liter of soda from the local Bobtown pizza.
Chevron recognizes the effect this has had on the community,” the company said on its website. “We value being a responsible member of this community and will continue to strive to achieve incident-free operations. We are committed to taking action to safeguard our neighbors, our employees, our contractors and the environment.”

Federal officials said Tuesday that toxic coal ash has coated the bottom of a North Carolina river as many as 70 miles downstream of a Duke Energy dump where a massive spill occurred two weeks ago.
The US Fish and Wildlife Service advised that a massive pile of coal ash about 75ft long and as much as 5ft deep has been detected on the bottom of the Dan river near the site of the February 2 spill. Deposits varying from 5in deep to less than 1in coated the river bottom across the state line into Virginia and to Kerr Lake, a major reservoir.
Federal authorities expressed concern for what long-term effect the contaminants will have on fish, mussels and other aquatic life. Public health officials have advised people to avoid contact with the water and not eat the fish.
“The deposits vary with the river characteristics, but the short- and long-term physical and chemical impacts from the ash will need to be investigated more thoroughly, especially with regard to mussels and fish associated with the stream bottom and wildlife that feed on benthic invertebrates,” said Tom Augspurger, a contaminants specialist at the federal wildlife agency. Benthic invertebrates are small animals that live in the sediments of rivers and lakes, such as clams, worms and crustaceans.

Toxins leaking from 2nd pipe at NC coal ash dump

Updated 6:33 pm, Tuesday, February 18, 2014
RALEIGH, N.C. (AP) — North Carolina officials said Tuesday that groundwater containing unsafe levels of arsenic apparently leaching from a Duke Energy coal ash dump is still pouring into the Dan River, which is already contaminated from a massive Feb. 2 spill.
The state Department of Environment and Natural Resources ordered Duke to stop the flow of contaminated water coming out a pipe that runs under a huge coal ash dump at its Eden power plant. A nearby pipe at the same dump collapsed without warning two weeks ago, coating the bottom of the Dan River with toxic ash as far as 70 miles downstream.
State regulators expressed concern five days ago that the second pipe could fail, triggering a new spill. The water coming out of that pipe contains poisonous arsenic at 14 times the level considered safe for human contact, according to test results released by the state on Tuesday.
"We are ordering Duke Energy to eliminate this unauthorized discharge immediately," said Tom Reeder, director of the N.C. Division of Water Resources.
Video taken last week by a robot sent inside the 36-inch-wide concrete pipe showed wide gaps between seams through which groundwater is gushing in, likely from the toxic dump above.
Tests on water from the pipe before it goes under the dump showed none of the dangerous contamination detected at the other end. The concrete inside the pipe is heavily stained around the numerous leaks, suggesting the contamination is likely not new.
A state inspector received the video recorded by Duke during a Feb. 11 visit to the site, but did not review it until Thursday. On Friday night, the state agency went public with concerns about the pipe's structural integrity.
Duke spokeswoman Paige Sheehan quickly issued a statement, downplaying the risk.
"After reviewing the videotape, we determined that no immediate action was necessary," it said.
In the wake of the initial spill, public health officials issued advisories telling people to avoid contact with the river water and not eat the fish.
Authorities said public drinking water in Danville, Va., and other communities downstream of the Duke plant remain safe. Heavy metals detected in the river at levels exceeding state and federal safety standards — including arsenic, lead and selenium — are being successfully filtered out of water drawn from the river at municipal treatment plants, they said.
The U.S. Fish and Wildlife Service said Tuesday a massive pile of coal ash about 75 feet long and as much as 5 feet deep has been detected in the river by the site of the Feb. 2 spill. Deposits varying from 5 inches deep to less than 1 inch coated the river bottom across the state line into Virginia and to Kerr Lake, a major reservoir.
Federal authorities expressed concern for what long-term effect the contaminants will have on fish, mussels and other aquatic life.
"The deposits vary with the river characteristics, but the short- and long-term physical and chemical impacts from the ash will need to be investigated more thoroughly, especially with regard to mussels and fish associated with the stream bottom and wildlife that feed on benthic invertebrates," said Tom Augspurger, a contaminants specialist at the federal wildlife agency.

The Deceit and Corruption behind the Keystone XL pipeline

New Evidence Submitted in State Department Hiring of Oil Industry Consultant to Write Keystone XL Environmental Review

Sierra Club | February 12, 2014 10:34 am

Today Sierra Club and Friends of the Earth submitted evidence to the State Department’s Office of the Inspector General to support the ongoing inquiry into conflicts of interest and mismanagement in the environmental review of the proposed Keystone XL pipeline. The groups request that the Inspector General takes steps to ensure that the tainted Final Environmental Impact Statement, released on Jan. 31, is excluded from the agency’s National Interest Determination.

“The State Department hired an oil industry consultant to write the environmental review of Keystone XL without taking steps to guard against industry bias,” said Doug Hayes, Sierra Club staff attorney. “So it’s no surprise that the report attempts to minimize the pipeline’s massive carbon pollution and threats to human health and water quality. This flawed report should have no place in the decision making on this pipeline.”
In Aug. 2013, the State Department confirmed that the Office of Inspector General (OIG) had opened an inquiry into the agency’s hiring of the consultant Environmental Resources Management (ERM) to prepare the environmental review of the project. Evidence shows that ERM made false and misleading statements on its application for the contract.
“By hiring ERM, the State Department ignored its own guidelines and invited the fox into the hen house,” said Ross Hammond, Friends of the Earth senior campaigner. “ERM has an obvious self interest in making sure Keystone XL is built.”
“The process that allowed them to get this contract has been corrupt from day one and the American people deserve better from their government,” Hammond continued. “It’s up to the Secretary Kerry and the Inspector General to restore some integrity and accountability into the review process, not preside over a whitewash.”

NEAT leaders: TransCanada dupes landowners about eminent domain

New concerns over the Keystone XL oil pipeline are prompting leaders of the Nebraska Easement Action Team, or NEAT, to send a letter to President Obama, Secretary of State Kerry and the Unicameral.
The letter expresses worry over TransCanada’s behavior and tactics in pursuing the proposed pipeline.
NEAT president Tom Genung, of Hastings, claims landowners are being misinformed about land seizures.
“Some of the land agents for TransCanada led landowners to believe that if they didn’t sign the initial proposal or the initial easement contracts that eminent domain would be implemented and that basically there would be no compensation,” Genung says, “which is not true at all.”

Landowner group warns of perceived plans to bypass federal permit for Keystone XL

February 12, 2014 6:00 pm  • 
A Nebraska landowner advocacy group is warning state legislators and landowners to be aware that TransCanada, the company responsible for the proposed Keystone XL pipeline, is offering easement agreements that mention bypassing the need for a presidential permit.
The Nebraska Easement Action Team Wednesday issued a strongly worded resolution condemning what it characterized as a history of deceptive practices by TransCanada and sought to bring attention to a sentence in a letter TransCanada sent this month to a Nebraska landowner.
The letter said if an easement was signed, paperwork wouldn't be filed with the county recorder until TranCanada gets a presidential permit for the 1,179-mile pipeline or “modifies the proposed Keystone XL Pipeline project in such a way that a presidential permit is no longer required.”
David Domina, an Omaha-based attorney who works with NEAT, said that single sentence changes the narrative TransCanada has put forth for years about building an international pipeline that requires a federal permit from Canada to refineries in Texas and Oklahoma.
“This (NEAT resolution) is intended as an alert to landowners and, frankly, to the members of the Legislature. There is something up. And we don’t know what it is,” Domina said. “This is not about the TransCanada Keystone XL pipeline project, this is about something new that isn’t being disclosed and we don’t know what it is.”
TransCanada Spokesman Shawn Howard said the company has no plans to avoid the need for a presidential permit.

Senior Officials Accused of Skewing Science to Benefit Keystone XL Pipeline

PEER | February 6, 2014 11:44 am
Managers within the U.S. Fish and Wildlife Service (FWS) overrode their scientific experts to adopt an inaccurate map based upon a flawed model that significantly shrank the range of an endangered species, according to agency investigative reports released today by Public Employees for Environmental Responsibility (PEER). The managers not only retaliated against scientists who voiced objections but rushed into publication of a bogus scientific journal article to cover their tracks.
abb2004
The American burying beetle is an endangered species threatened by the Keystone XL tar sands pipeline.
The American burying beetle (ABB), a critically endangered species, has seen its range dwindle from 35 states to the plains of South Dakota, Arkansas, Nebraska and Oklahoma —areas in the proposed path for the $5.3 billion Keystone XL oil pipeline.
Based on complaints from FWS scientists, specially convened Scientific Integrity Review Panels found two “high-level” officials guilty of scientific misconduct. The panels found that Dixie Porter, supervisor of the FWS Oklahoma Ecological services field office in Tulsa, OK, and Luke Bell, FWS Branch Chief for Threatened and Endangered Species and Contaminants:
  • Adopted flawed models that dramatically shrunk the known range of the ABB
  • Compounded their misconduct by improperly rushing an article into publication that both “knowingly impeded” the original panel investigation and also would “further degrade the endangered status of the ABB.…” Despite this finding, FWS has yet retract the paper.
  • Retaliated against line scientists who objected, including imposition of “several staff suspensions.” 
This is the first time an Interior agency has upheld a scientific misconduct complaint under its relatively new Scientific Integrity policies. Yet FWS refused to release the reports to PEER under the Freedom of Information Act. PEER obtained them by filing an appeal with Interior’s Office of Solicitor, the administrative step before a lawsuit, and the solicitor ordered release of redacted versions of the reports.

Published February 14, 2014
Climate change has been the focus of much of the opposition to TransCanada's Keystone XL pipeline. But many conservationists are also concerned about more immediate environmental consequences.
They're worried about the pipeline construction's impact on wildlife and ecosystems, and of possible spills of the heavy crude oil that will flow through the pipeline at the rate of 830,000 barrels a day. (See related: "Interactive: Mapping the Flow of Tar Sands Oil.")
Some people, seeing a map of the pipeline's proposed 875-mile route through the Great Plains, may picture the region in the terms of 19th-century explorers who called it the "great American desert": a barren land lacking in natural-history interest. In fact, though the vast herds of grazing animals that Lewis and Clark saw are greatly diminished, rich ecosystems endure. And while the pipeline route crosses some agricultural land, much of it would traverse natural habitats in Montana, South Dakota, and Nebraska where harmful effects on native animals and plants could—some say would, inevitably—occur. (See related, "Oil Flows on Keystone XL's Southern Leg, But Link to Canada Awaits Obama Administration.")

Rich ecosystems surround the Missouri and Yellowstone Rivers (the latter is pictured here). Keystone XL would cross both rivers in Montana.
Missouri and Yellowstone Rivers
The Keystone XL route crosses the Missouri and Yellowstone rivers, two of more than 50 crossings of perennial streams. Both rivers are home to the federally endangered pallid sturgeon, a bizarre-looking fish up to six feet long adapted to life in large rivers with silty bottoms. A serious oil spill has the potential to damage or even destroy habitat for this species. Such a spill could also harm habitat for least terns and piping plovers, two birds that nest along rivers and that have suffered serious declines in recent decades.
And pipelines do fail, conservationists note. The failure in 2010 of an Enbridge pipeline carrying Canadian crude oil triggered the costliest onshore oil spill in U.S. history, contaminating 40 miles of Michigan's Kalamazoo River and surrounding wetlands. Last year, another pipeline carrying Canadian oil, Exxon-Mobil's Pegasus line, ruptured in a the small Arkansas town of Mayflower, affecting wetlands connected to the largest man-made game and fish commission reservoir in the United States. (See related, "Oil Spill Spotlights Keystone XL Issue: Is Canadian Crude Worse?") Officials are still reckoning the lingering environmental damage after massive and expensive cleanup efforts.
In its recent Final Supplemental Environmental Impact Statement, the State Department admits that oil spills will occur and are a danger, but asserts that current technology and rigorous inspections make the odds of a serious spill remote. (See related, "3 Factors Shape Obama's Decision on Keystone XL Pipeline.")
Davis Sheremata, a spokesperson for TransCanada, said Keystone will incorporate construction and maintenance techniques more advanced than those of earlier pipelines. Safety measures "are the culmination of six years of consultation between TransCanada, the United States Fish and Wildlife Service, and many other federal and state environmental agencies," he said. "The required environmental protection and pipeline safety measures set a new, and very high, standard unequaled by any other pipeline project."
Whooping Crane
One of the greatest conservation concerns about the immediate effect of the pipeline centers on the critically endangered whooping crane. Most of these tall white birds nest in Canada and migrate through the central United States to and from their wintering grounds on the Texas Gulf Coast. The cranes' flight route passes directly along the pipeline route for hundreds of miles.
It's not the pipeline itself that's of greatest potential danger to the cranes, though. Pumps needed to keep the thick Canadian oil flowing through the pipeline require power lines to supply them with electricity, and conservationists wonder what will happen when more than 300 miles of new power lines appear in formerly wide-open spaces in the birds' flight path.
"The whooping crane is a species that we've really homed in on," said  Jim Murphy, senior counsel for the National Wildlife Federation. "Power lines account for about 40 percent of juvenile whooping crane mortality, which is a big deal when you're talking about a bird that has a population of about four hundred in the wild. Those concerns have never really been taken seriously."
TransCanada's Sheremata said his company and pipeline contractors "have committed to incorporate a number of conservation measures to prevent potential direct or indirect impacting to the whooping crane." Measures include installing and maintaining avian markers (conspicuous objects designed to make lines more visible to flying birds) at pump stations "to reduce impacts to whooping cranes from power lines."

Greater Sage-Grouse
Although the greater sage-grouse isn't officially an endangered species, many bird experts believe it should be. They claim it has been kept off the list for fear of political backlash in conservative western states, where farming and ranching might face restrictions.
There's no question that the grouse has suffered from loss of habitat: 20 of 27 known population groups have declined since 1995. The pipeline route passes within a few miles of dozens of grouse leks (sites where males "dance" to attract mates); ornithologists fear that noise from construction, roads, and pumping stations could affect breeding success of these notoriously shy and easily disturbed birds.
In addition, power-line towers serve as hunting perches for eagles and hawks, which prey on grouse. In treeless areas where grouse live, towers will bring new threats and greater potential mortality by providing raptor lookouts where formerly there were none.

The swift fox, a small canine of grassland regions, is another controversial species that the Arizona-based Center for Biological Diversity believes belongs on the endangered-species list. The CBD finds it "dumbfounding" that Keystone XL environmental-impact statements fail to address the pipeline's effects on the fox.
"It's like they took a map and drew a pipeline along the remaining locations of known bands of the swift fox," said Amy Atwood, senior attorney for the CBD. "That's where the fox lives, because those are the areas that are not being used for agriculture and are on public land. That's where pipeline companies like to site things these days to minimize landowner conflict or having to deal with eminent domain. And that's where the wildlife is. They've been pushed out of other areas."

Ogallala Aquifer


From Wikipedia:  

The Ogallala Aquifer is a shallow water table aquifer located beneath the Great Plains in the United States. One of the world's largest aquifers, it underlies an area of approximately 174,000 mi² (450,000 km²) in portions of eight states: (South DakotaNebraskaWyoming,ColoradoKansasOklahomaNew Mexico, and Texas). It was named in 1898 by N.H. Darton from its type locality near the town ofOgallala, Nebraska. The aquifer is part of the High Plains Aquifer System, and rests on the Ogallala Formation, which is the principal geologic unit underlying 80% of the High Plains.

About 27 percent of the irrigated land in the United States overlies the aquifer, which yields about 30 percent of the ground water used for irrigation in the United States. Since 1950, agricultural irrigation has reduced the saturated volume of the aquifer by an estimated 9%. Depletion is accelerating, with 2% lost between 2001 and 2009[ alone. Certain aquifer zones are now empty; these areas will take over 100,000 years to replenish naturally through rainfall.

The aquifer system supplies drinking water to 82 percent of the 2.3 million people (1990 census) who live within the boundaries of the High Plains study area.
