White Sturgeon Rebound With Help From Kootenai Tribe of Idaho

At first glance they look like miniature tadpoles. Stare a little harder, though, and tiny sturgeon features become apparent. The white sturgeon hatchlings are in the midst of a comeback brought about by the Kootenai Tribe of Idaho.

A nearby hatchery tank swarms with year-old sturgeon, their large bodies and broad pectoral fins narrowing down to high, pointed tails much like fighter jets. The adults are in huge tanks, only a few fish but each seven or eight feet long.

White sturgeon were here when dinosaurs roamed the country, but man has now put this population of sturgeon in danger of extinction. Historically they were a very important food source for people along the Kootenai River, but they were more than just food.

“Sturgeon were looked upon as our grandfathers,” said tribal chairperson Jennifer Porter, sharing a story told to her by a tribal elder. “Sturgeon could live to be over a hundred years old. They knew the river. They knew the land. Our families would ask the sturgeon, our grandfathers, to guide them through. They were the ones who knew how to go up and then back down the river.”

Sturgeon are the largest freshwater fish in North America and can reach weights well over a thousand pounds, and lengths in excess of 12 feet. Human activity over the past 50 years has drastically reduced their number. In 1994 they were listed as an endangered species.

The Kootenai Tribe of Idaho stepped in with a management plan to help recover sturgeon within the Kootenai River. That program continues and is growing stronger, but much is left to be done. A sturgeon hatchery was constructed in 1991 and still supplies thousands of young fish to the river each year. Hatchery manager Chris Lewandowski said that a cyclical maintenance grant from Bureau of Indian Affairs for Native American hatcheries has allowed some recent improvements. This includes a spawning room, new vapor barrier, and waterproof paneling in some of the fish buildings. Improvements are planned during the coming months for additional improvements with funding from the Bonneville Power Administration.

Hatchery workers spend many days through the spring months using rods and reels to catch these huge fish, take them to the hatchery and hold them till the females are ready to spawn. After eggs are collected, the adult fish are then returned to the Kootenai River.

This is the majestic fish’s only shot at reproduction. Construction of Libby Dam in Montana 50 years ago affected spawning habitat and river flows downstream. Little or no natural recruitment to the population has occurred since that time. Essentially the only addition of young fish comes from those released from the hatchery.

“We spawned nine females this year with approximately 225,000 eggs collected from these fish,” Lewandowski said. “We used a total of twelve males in combination with the nine females to make seventeen family groups.”

Some males were used with more than one female to make up these groups. Five groups, 75,000 eggs, were sent to a backup facility in British Columbia.

“This serves as a failsafe to make sure we have survival from at least one facility in a given year,” Lewandowski said, adding that the young fish will also be released throughout the Kootenai River.

The 2013 spawning season met all the established goals. The hatchery is designed to rear 12 sturgeon families comfortably. During the mid-2000s they reared as many as 18 families but found that the increased density in the tanks caused higher mortality rates. The number of families was reduced to 12, and the result is less mortality. In addition, average size at release doubled to the present 5565 grams. Thirty grams is considered minimum for the fish to have a good chance of survival.

Young fish are reared in the hatchery for 16 to 18 months before being released, Lewandowski said. On average about 10,000 fish are released annually. A second hatchery several miles north of the present hatchery is also underway and should be ready in early 2014.

“The new hatchery will give us more rearing space to provide a quality fish while improving genetic diversity by being able to spawn more females,” Lewandowski added.

Beyond Keystone XL: Three Controversial Pipelines You Probably Haven’t Heard Of

By Kiley Kroh, Climate Progress

While the national debate remains largely focused on President Obama’s impending decision regarding the controversial Keystone XL pipeline, communities across the U.S. and Canada are grappling with the oil and gas industry’s rapidly expanding pipeline network — cutting through their backyards, threatening water supplies, and leaving them vulnerable to devastating spills.

As production booms in Alberta’s tar sands and fracking opens up vast oil and natural gas deposits around America, companies are increasingly desperate for new pipelines to get their product to market. “We’ve so narrowly focused on Keystone that a lot of these other projects aren’t getting the scrutiny they probably need,” said Carl Weimer, executive director of the Pipeline Safety Trust. He explains that as production skyrockets and companies look to cash in, no one is really in charge of it all. “We’re leaving it up to these individual companies to come up with their own solutions to figure out how to move energy and we don’t have any national policy guiding those decisions.”

According to a recent analysis of federal Pipeline and Hazardous Materials Safety Administration data, since 1986 there have been nearly 8,000 incidents, resulting in more than 500 deaths, more than 2,300 injuries, and nearly $7 billion in damage.

Here are three of the most recent pipeline controversies emerging around the country:

1. Bluegrass Pipeline

Opposition is growing to the proposed 500-mile bluegrass pipeline, which would transport flammable natural gas liquids across Kentucky to an existing line that terminates in the Gulf. Landowners and environmentalists gathered at the state capital last week to protest the project, which they fear would threaten water supplies and safety. Residents were caught off guard by the project — landowner Stacie Meyer said she noticed survey markers going up near her property and had to search the internet and consult her neighbors to find out what they were for.

Locals are concerned the company, Williams Co., could use imminent domain to seize the land if opposition proves too strong. As the Courier-Journal reported, “Brad Slutskin, a Woodford County landowner who spoke at the rally, said the pipeline companies are threatening condemnation based on a loose interpretation of Kentucky law, and most property owners don’t have the money to mount a court challenge.” Residents opposed to the pipeline — including a group of nuns and monks who are refusing to give up their land for the project — delivered a petition with more than 5,200 signatures asking Gov. Beshear to include pipeline and eminent domain-related issues in the upcoming special legislative session, which he refused.

“Knowing a pipeline is coming through, is like waiving a red flag to the creatures of the Earth. God created Earth as our land to use not abuse,” Sister Joetta Venneman told local WAVE News.

As the gas fields north and east of Kentucky boom, the state will likely find itself in the crosshairs of many battles to come. In fact, while the fifth Kentucky county was passing a resolution opposing the Bluegrass Pipeline on Wednesday, the Courier-Journal reported that the project may already have some competition — a joint venture to convert an existing natural gas line called the Tennessee Gas Pipeline.

Facing resistance in the U.S. over its Keystone XL proposal, TransCanada Corp. is moving forward with plans for another tar sands pipeline project that would carry almost as much crude as Keystone. The new pipeline, the most expensive in TransCanada’s history, would run from Alberta to the Atlantic seaboard, ending where a new deep-water marine terminal would be built to export the crude overseas. In early August, TransCanada said it received the long-term contracts for about 900,000 barrels of crude per day and Canadian Prime Minister Stephen Harper has already indicated his support for the project.

TransCanada’s proposal has been met with stiff opposition from Canadian environmentalists and native leaders — particularly in Quebec, where Premier Pauline Marois has halted natural gas exploration while last month’s deadly Lac-Megantic crude oil train explosion is still being cleaned up.

The $12 billion development plan calls for converting 1,864 miles of an existing, 55-year-old pipeline currently used for natural gas to carry the oil. Though the proposed route does not cross into the U.S., it does skirt the border with Maine. Perhaps most worrisome to residents of Maine, New Hampshire and Vermont, however, is that the increased shipping capacity from Alberta will impact another pipeline — the 70-year-old Portland Pipeline. Currently, the pipeline is used to ship crude into Canada but residents are concerned the flow will be reversed to bring Canadian tar sands into the U.S. As the Boston Globe explains, “this would provide Canada — whose Alberta-centered oil industry is suffering from too much supply and too little access to overseas markets — its first direct pipeline to a year-round, deep-water port.” Residents throughout New England are staunchly opposed to the region becoming a conduit for the dirtiest form of fossil fuel production, holding anti-pipeline demonstrations in Portland, while 29 Vermont communities passed resolutions banning tar sands oil from the state.

For now, residents of Maine, New Hampshire and Vermont are left with little option other than waiting to see how the Energy East pipeline development may impact the Portland Pipeline. In a statement released earlier this month, the company said, “It is uncertain to us what the entire impact of this proposed project might be on crude movements and crude supplies for the East Coast. We are continuing to evaluate this recent development.”

3. Eastern Gulf Crude Access Pipeline Project

Enbridge’s proposed 774-mile pipeline would run from Illinois to Louisiana and carry oil from North Dakota’s Bakken formation, as well as Canadian tar sands. The pipeline would be capable of transporting almost as much crude as Keystone XL and, as Inside Climate News reports, will likely sail through the regulatory process because much of the pipeline is already constructed as a natural gas line.

“Converting pipelines makes [approval] easier and riskier, too,” explains Weimer. “Keystone is brand new, state of the art pipeline with its own set of problems. Enbridge on the other hand, is converting other pipelines that have already been in the ground for years — putting in new types of crude or switching natural gas to liquid on pipelines that aren’t built to today’s standards. Those old pipes being re-purposed certainly presents a new risk.”

While the Keystone decision is momentarily stalled, Eastern Gulf is just one of many new pipelines being built to ship North American oil to the Gulf Coast for refining and export. According to Inside Climate, “Enbridge plans to build thousands of miles of pipelines over the next few years, including an expansion of its Alberta Clipper pipeline from Canada to Wisconsin. If approved, that line would ship up to 880,000 barrels of Canadian crude into the United States each day, compared to the Keystone’s capacity of 830,000 barrels per day.”

Last month, all five members of Minnesota’s Public Utilities Commission approved increasing the flow of the Alberta Clipper line while refusing concerned citizens the opportunity to testify publicly. The initial expansion still awaits approval from multiple government agencies but Enbridge already has its sights set on a second expansion, which wasn’t discussed at the meeting. The protesters, including several Native American representatives, fear their communities could soon face the same devastating impacts of tar sands development being felt in Alberta. Marty Cobenais of Bemidji, part of the Indigenous Environmental Network, told the Bemidji Pioneer that the pipeline is a major issue for his Red Lake community. “This is huge,” he said. “This is in our back yard.”

These fights are just three of many being waged by citizens across the country. Alabama residents, for instance, have been protesting multiple pipeline projects — including the Plains All-American oil pipeline, which would run 41 miles to Mississippi and through a section of Mobile’s drinking water supply.

Though pipeline companies are seeking to capitalize on the Lac-Megantic tragedy to tout the safety of crude transport over rail, the devastating impacts of pipeline spills are impossible to overlook. Last week, the New York Times profiled two communities in Michigan and Arkansas that are forever changed by tar sands pipeline spills. Though it’s been three years since Enbridge’s pipeline rupture that spewed more than 840,000 gallons of tar sands crude into Michigan’s Kalamazoo River, the region is far from restored. And even despite EPA’s recent order for Exxon to dredge the river, an EPA spokeswoman estimated that 1620,000 gallons of oil will remain in the Kalamazoo.

And in March, an Exxon Mobil pipeline burst, spilling an estimated 210,000 gallons of crude into a Mayflower, Arkansas neighborhood. What’s left behind is bleak: “Four months later, the neighborhood of low-slung brick homes is largely deserted, a ghostly column of empty driveways and darkened windows, the silence broken only by the groan of heavy machinery pawing at the ground as remediation continues.” As Inside Climate News has continued to report, residents are now grappling with the long-term effects of the toxic spill, including the difficult process of relocating their families and the frightnening health complications that have begun to manifest.

In addition to re-purposing old pipelines, there are several aspects of the unchecked expansion of fossil fuel pipelines across the country that has Weimer concerned. First, pipeline regulation needs to be strengthened and clarified. He explains that right now, “regulations are written in such a way that to a vast degree, it’s left up to the pipeline companies to figure out how safe their pipelines are and what to do about it.” And it’s not just oversight — planning future pipeline routes is also dictated by the companies themselves. “The way we leave it up to each company means we could have multiple pipelines from different companies moving [their products] through the same place. Each company is just trying to capitalize and make money. State and local government really hasn’t thought about it much — is unprepared — and pipelines will go into place before there are policies to guide the construction. It can really affect the way local communities may develop and often happens before the community has any sense of what they can do about it.”

Seeping Alberta Oil Sands Spill Covers 40 Hectares, Still Leaking

Source: ICTMN

As debate rages south of the 49th Parallel over developments such as the Keystone XL pipeline, bitumen from four underground oil spills is quietly seeping into wetlands and soils in the oil sands in northern Alberta—and has been for at least three months, if not longer.

Bitumen leakage now totals at least 1.2 million liters—about 8,024 barrels, or 317,000 gallons, the Alberta Energy Regulator, a provincial agency, said in an August 16 update. And despite claims by the operator, Canadian Natural Resources Limited, that the spills are contained and being remediated, recent provincial statements indicate that that is not the case.

“It’s ongoing. The spill is still ongoing,” said Cara Tobin, a spokesperson for the provincial agency Alberta Energy Regulator, to the website DesmogCanada.com on August 6. “There is still bitumen coming up from the ground.”

The spills at Canadian Natural Resources’ Primrose facility first came to light in mid-July, but they had been ongoing for weeks, and one may even date back to last winter, the Toronto Star reported on July 19. The operations lie on the Cold Lake Air Weapons Range, which is also an active weapons-testing site for the Canadian military and thus restricted to public access.

Documents brought to light by the Star show that 26,000 barrels of bitumen combined with surface water had been removed between May, when cleanup began, and mid-July, when the spills came to light via a television station. More than 4,500 barrels were straight bitumen, the Star reported. The latest update nearly doubles that number.

“Everybody [at the company and in government] is freaking out about this,” said a whistle-blowing government scientist to the newspaper back in July. “We don’t understand what happened. Nobody really understands how to stop it from leaking, or if they do they haven’t put the measures into place.”

The company issued a statement on July 31 saying that it was remediating the spills.

“Each location been secured, clean up, recovery and reclamation activities are well underway,” the company said. “The bitumen emulsion does not pose a risk to health or human safety.”

Nearby Cold Lake First Nation, whose residents are Dene, was of a completely different mind.

“We are extremely alarmed with the environmental damage from the blow out that occurred at Cold Lake Weapons Range as this is in the federally recognized traditional territory of Cold Lake First Nations and close to CLFN Indian Reserve 149C,” said Cold Lake First Nation Chief Bernice Martial in a statement on August 7. “We contacted Canadian Natural Resources Limited (CNRL) to express CLFN’s concerns and we are now demanding answers and want factual information on the contamination of four recent surface releases of bitumen emulsion from oil wells.”

Canadian Natural Resources did admit that “unfortunately some animal fatalities have occurred including 16 birds, 7 small mammals and 38 amphibians. Two beavers, two birds and two muskrats are currently being cared for prior to being returned to their natural environment.”

Critics of the process being used to extract the bitumen suspect that the leaks stem from a method of “steaming” the ground in a process not unlike fracking (hydraulic fracturing of rock that loosens oil and gas deposits in shale). Steaming entails injecting highly pressurized water into the sands to melt the bitumen so that it can be pumped to the surface. Canadian Natural Resources said that its process is not the cause—the company does not use enough pressure to cause that type of leakage, a spokesman told the Star, and blames instead improperly capped wells from other companies’ defunct operations.

The Dene are demanding not only answers but inclusion in the evaluation and cleanup process as well.

“Our community needs to be respectfully involved in the remediation of this environmental disaster as our health and safety hangs in the balance,” Martial said. “We live, hunt, fish in the area and need to know the damage that has been done to our land, water and wildlife.”

Blackfeet Tribal Council says energy leases on religious site cancelled

David Murray, Great Falls Tribune

The Blackfeet Tribal Business Council issued a news release Wednesday stating proposed oil and gas leases near Chief Mountain have been canceled. The mountain, located near the Canadian border and on the boundary between the Blackfeet Indian Reservation and Glacier National Park, is considered sacred by many of the Blackfeet people.

“The current proposed leases by Nations Energy, which are the subject of so much misinformation, were canceled on July 24, 2013 due to nonpayment by the company,” the tribal council news release states. “The intention of such leases was to explore an area of the reservation which is at least two miles from Chief Mountain and at least one half mile from the mandated buffer zone.”

The tribal council’s announcement comes three days prior to a planned protest in opposition to oil and gas development at the site. Reports that the council had approved exploration leases at Chief Mountain became public last week after a conservation activist posted lease documents purportedly obtained from the Bureau of Indian Affairs (BIA) on his web site.

Included within those documents is a resolution signed by council chairman Willie Sharp, Jr. and acting council secretary Roger “Sassy” Running Crane reaffirming a prior resolution from January 3, 2013. The resolution approves the mineral lease development of 4,000 acres of tribal land by Nations Energy, LLC, with three wells to be developed within a five year primary term, the first to be drilled within 18-months of the lease signing.

Publication of these documents prompted a petition drive in opposition to the development, which had gathered more than 2,200 signatures by Wednesday afternoon.

The Blackfeet Tribal Business Council’s news release notes that as far back as 1982, nontribal people were prohibited from making incursions into a one mile buffer zone around the base of Chief Mountain, and that this protection was reaffirmed by tribal council action in 1992.

“The Blackfeet Tribal Business Council has always considered Chief Mountain as one of the most sacred sites on the Blackfeet Reservation,” the news release states. “This area was for spiritual use of the Blackfeet people only. This protection continues to this day and nothing has or will disturb this area, including any oil and gas development.”

It continues on to state that even if the agreement with Nations Energy had advanced to the drilling of wells, the tribe would have first had to complete an environmental and cultural resources study to see if the proposed wells would impact any Blackfeet cultural resources.

“However, since the leases no longer exist, this is not an issue,” the news release concludes.

The tribal council goes on reassert its “absolute right to develop its own resources on its own land.”

“The council is clear in its purpose to create a better economic environment for its people who currently suffer some of the highest rates of poverty and unemployment in the United States,” the news release states. “With that responsibility to better the lives of its people, however, comes the absolute mandate to do no harm to the tribe’s cultural sites, traditions and resources, including water. The two duties go hand-in-hand and this council will follow its oath and the Blackfeet Constitution to protect and defend its land and to responsibly develop its many and valuable resources.”

Quinault Nation Passes Resolution to Oppose Coal Exports

Source: Indian Country Today Media Network, August 16, 2013

The Quinault Indian Business Committee has passed a resolution opposing proposals to export coal from the Pacific Northwest. The resolution, passed Monday, specifically addresses a proposal to transport coal by rail from the Powder River Basin in Wyoming through Washington State for export from Cherry Point in Anacortes. There are other locations in Washington and British Columbia under consideration, including Longview, said Fawn Sharp, President of the Quinault Indian Nation.

“This resolution is a strong statement by the Quinault Nation and demonstrates its commitment to protect and promote the health, safety and general welfare of our people,” said Sharp, who is also President of the Affiliated Tribes of Northwest Indians. “We have determined that the coal trains are detrimental to the health of our people and to the natural resources of our region, and thus in violation of our treaty-protected rights,” she said.

“We have serious concerns about the long-term effects of pollution caused by burning coal from Asian countries, many of which lack the pollution standards we are used to within the United States. Emissions from coal-fired plants have the potential to further threaten our oceans and fisheries, already severely impacted by the acidification of the water, added Sharp.

The Quinault Indian Nation is signatory to the Treaty with the Quinault of 1855. It, along with other Northwest treaties, has been repeatedly reaffirmed by the federal government, including the U.S. Supreme Court, and is thus legally classified as the “supreme law of the land” under Article VI of the U.S. Constitution.

“Coal dust and diesel particulates will find their way into our air and waterways as these trains pass along and over our rivers, doing damage to natural resources upon which the Nation depends,” said Sharp. “The United States Environmental Protection Agency, Tribal governments, and environmental organizations have voiced concerns over the threat to human health these proposals bring because of the adverse health effects of coal dust and diesel pollution, including bronchitis, emphysema, lung damage, asthma, and cancer. Our elders and our children are particularly vulnerable because of sensitivity to the health effects of fine particles,” she said.

“The Quinault Nation’s treaty fishing right includes a right of access to its traditional fishing, hunting, and gathering sites that will be impacted by increased vessel and rail traffic.

In the Resolution, the Quinault Business Committee expresses its solidarity and support for the “no” position regarding the Gateway Pacific Terminal proposal adopted by the Lummi Indian Business Council, based on documented disturbance of sacred burial grounds and proposed fill of that area for the purpose of containing over a hundred acres of coal piles.

The Resolution also endorses the words of Billy Frank, Jr., Nisqually tribal elder and longtime chairman of the Northwest Indian Fisheries Commission that, “We are at a legal and biological crossroads in our efforts to recover the salmon and preserve our tribal cultures, subsistence, spirituality, and economies. Not since the darkest days of the fishing rights struggle have we feared so deeply for the future of our treaty rights.” Quinault Nation, one of 20 member tribes of the Northwest Indian Fisheries Commission, is signatory to “Treaty Rights at Risk” submitted to the federal government by that Commission. Among other things, that report states that coal export proposals will, in fact, further endanger Treaty Rights.

The Quinault Resolution will be submitted to President Obama, key members of the federal Administration, key members of Congress and to Governor Inslee.

Dakota oil could add risks to rail transport

Bloomberg News

WASHINGTON — Crude oil shipped by railroad from North Dakota is drawing fresh scrutiny from regulators concerned that the cargo is adding environmental and safety hazards, something that analysts say could raise costs.

The Federal Railroad Administration is investigating whether chemicals used in hydraulic fracturing are corroding rail tank cars and increasing risks. Separately, three pipeline companies including Enbridge Inc. warned regulators that North Dakota oil with too much hydrogen sulfide, which is toxic and flammable, was reaching terminals and putting workers at risk.

Until last month, safety advocates’ chief worry was spills in derailments. After tank cars blew up July 6 on a train in Quebec, investigators in Canada are considering whether the composition of the crude, which normally doesn’t explode, may have played a role in the accident that killed 47 people. The oil was from North Dakota’s Bakken shale.

“Crude historically has not been considered in the highest category of hazmat,” said Anthony Hatch, an independent analyst in New York who has tracked railroad companies for almost three decades. “The risks have been considered to be environmental, not to humans. Perhaps Bakken crude should be considered in a higher category.”

The cost of added safety measures, such as tighter rail-car specifications that would make obsolete some current models, may become an issue if oil prices fall, according to Kevin Book, managing director at ClearView Energy Partners, a Washington-based policy-analysis firm.

“The solution to rail safety issues looks like unanticipated costs, whether, it be rail car investments or new safety protocols,” Book said.

Such costs are less likely to slow production when is oil trading for $100 or more per barrel, Book said. “At $75 per barrel, it could be a big deal,” he said. Crude oil futures have traded higher than $100 a barrel since July, and are more than $90 a barrel since late April.

North Dakota is the nation’s second-biggest oil-producing state, with more than 790,000 barrels a day this year up from from about 150,000 barrels in 2008. Railroads move 75 percent of the state’s crude, including the load of more than 70 cars that derailed and exploded last month in Lac-Megantic, Quebec.

Canadian regulators are testing the composition of crude from the wrecked Montreal Maine & Atlantic Railway Ltd. freight train. A question they say they’re asking is why the derailment led to such an intense inferno, which regulators have called “abnormal.” They visited North Dakota as part of their review, said Chris Krepski, a spokesman for the Transportation Safety Board of Canada.

“We did take samples from the tank cars to get a better understanding of what was actually carried in them and verifying that against the shipping documents,” Krepski said. “It’s safe to say we’re looking at everything.

Montreal, Maine & Atlantic said last week it was forced to file for bankruptcy because of potential liability in the crash.

Much of North Dakota’s production relies on hydraulic fracturing or fracking, a technique in which millions of gallons of chemically treated water and sand are forced underground to shatter rock and free trapped oil. Highly corrosive hydrochloric acid is widely used to extract oil in the state, according to a 2011 report from the Society of Petroleum Engineers.

In a July 29 letter to the American Petroleum Institute, a Washington-based lobbying and standards-setting group for the oil and gas industry, the railway administration said it found increasing cases of damage to tanker cars’ interior surfaces. A possible cause is contamination of crude by materials used in fracking, according to the letter.

“If the hydrochloric acid is carried with the oil into rail cars, corrosion can be an issue,” said Andy Lipow, president of Houston-based Lipow Oil Associates.

Shippers need to know the properties of the oil to ensure that it’s transported in tankers equipped to handle the cargo, according to the rail agency’s letter. Because information provided to railroads on the properties of oil is not gathered from tests, the agency said it “can only speculate” as to the number of cars in violation of hazardous-materials regulations.

Investigating whether the chemical composition of Bakken oil makes it more likely to corrode tank cars is reasonable, said Peter Goelz, a former National Transportation Safety Board managing director who’s now a senior vice president with O’Neill and Associates in Washington.

The Quebec accident also revived a debate over the type of cars used to haul oil. For years, regulators and watchdogs have sought improvements to a common car design shown to be susceptible to rupture when derailed. The NTSB estimates that 69 percent of today’s rail tank-car fleet has “a high incidence of tank failure during accidents,” Chairman Deborah Hersman wrote last year. The agency recommendeds thicker shells and other modifications to strengthen the cars.

Sen. Charles Schumer, D-N.Y., this week called on U.S. regulators to phase out the older cars, known as DOT-111s, saying they’ve contributed to spills of hazardous materials.

“The DOT-111 tank car has proven particularly prone to spills, tears and fires in the event of a derailment, and it’s simply unacceptable for New York’s communities along the rail lines to face that risk when we know thicker, tougher cars could keep us safer,” Schumer said.

The rail industry is fighting a proposal to retrofit existing cars, saying it could cost as much as $1 billion.

Shippers also must account for hydrogen sulfide, a highly flammable toxic gas that at some wells is a byproduct of oil, to properly classify oil for transport. The Bakken oil field generally produces lighter oil with little or no hydrogen sulfide, though at times, crudes with different grades are mixed for shipping, said John Harju, associate director for research at the University of North Dakota Energy and Environmental Research Center, and co-author of the Society of Petroleum Engineers report on the Bakken reservoir.

“You see little blender facilities popping up all over the place along pipelines and rails,” Harju said.

In June, Enbridge won an emergency order to reject oil with high hydrogen-sulfide levels from its system after telling the Federal Energy Regulatory Commission that it found dangerous levels of the compound at a rail terminal in Berthold, N.D. In addition to being highly flammable, hydrogen sulfide in the air is an irritant and a chemical asphyxiant that can alter both oxygen utilization and the central nervous system, according to the U.S. Occupational Safety and Health Administration.

“We did discover that some of the crude coming into the system had much higher levels of hydrogen sulfide than we felt was safe for our employees,” said Katie Haarsager, an Enbridge spokeswoman. “Some blending may not have been up to levels in the past.”

Enbridge won FERC’s permission to refuse delivery of any oil with hydrogen sulfide that exceeded 5 parts per million, half the minimum exposure recommended by federal regulators. In a May 5 test, Calgary-based Enbridge, which owns and operates a 970-mile pipeline from Plentywood, Montana, to Clearbrook, Minn., found levels as high as 1,200 parts per million at its Berthold terminal “that could cause death, or serious injuries,” according to the company’s FERC filing.

Two other pipeline operators, Tesoro Corp. and the closely held True companies, which operates the Belle Fourche and Bridger pipelines in North Dakota, also found high levels of hydrogen sulfide in crude shipments. The FERC approved Tesoro’s request to reject oil with hydrogen sulfide at more than 5 parts per million effective Jan. 1. True companies was allowed to turn away crude with more than 10 parts per million of hydrogen sulfide effective April 1

True, based in Casper, Wyo., sent a notice to its Belle Fourche and Bridger customers in January warning that high levels of hydrogen sulfide “materially affected the common stream and created safety hazards at certain delivery locations.

North Dakota regulators say hydrogen sulfide is prevalent in oil wells in some areas and field inspectors are required to carry hydrogen-sulfide monitors.

“The fact that there were explosions, and crude oil is not supposed to explode, raises a lot of suspicions as to whether there were other chemicals and so on added to oil in the process before the shipment,” said Edward Burkhardt, chief executive officer of Rail World Inc., which owns the Montreal and Maine railway.

While derailments of trains hauling crude can create environmental messes, oil doesn’t usually ignite unless exposed to extreme heat, said Lloyd Burton, professor of environmental policy at the University of Colorado in Denver. Gasoline, refined from crude oil, is more more volatile.

“Crude oil doesn’t usually explode and burn with the ferocity that this train did,” Burton said.

State reminding people to cook shellfish after increase in illnesses

Published: August 14, 2013

By KIE RELYEA — THE BELLINGHAM HERALD

Three people in Whatcom County have become sickened by saltwater bacteria after eating undercooked or raw crab and oysters – part of a statewide surge totaling 44 probable or confirmed cases of the intestinal illness.

The number of cases of people sickened by vibrio bacteria is about twice what it was for this time last year; about 40 to 80 cases are reported annually.

“We seem to be in an active season,” said Rick Porso of the state Department of Health’s Office of Shellfish and Water Protection.

Most cases occur during summer.

The worst outbreak in recent years was in 2006, when Washington had 80 lab-confirmed vibrio cases, with 36 of them in King County, according to the King County Health Department.

Of the 44 confirmed or probable cases so far this year, King County has 21.

To avoid being sickened, health officials recommend cooking all shellfish during the summer to kill the bacteria.

“It is completely preventable with cooking, so that’s what we urge people to do this time of year,” Porso said.

Vibrio parahaemolyticus, the bacterium that causes the illness, occurs naturally in marine coastal waters.

In low numbers, vibrio doesn’t sicken people. But when water temperatures rise, the bacteria multiply rapidly – raising the risk of vibriosis illness among people who eat raw or undercooked shellfish, particularly oysters.

Public health officials believe the warm summer and daytime low tides contributed to the recent illnesses, and expect more to occur in the coming weeks because current conditions are likely to continue.

Vibriosis causes flu-like symptoms that can include diarrhea, nausea and vomiting. Symptoms usually appear 12 to 24 hours after eating infected shellfish.

The illness is usually mild to moderate and lasts two to five days, but it can be life-threatening to people with weak immune systems or chronic liver disease. People who take antacids also can become very sick.

The three cases reported in Whatcom County were from recreational harvesters who fell ill after eating oysters and crab.

Here’s what people should do to kill the bacteria and avoid becoming sick:

– Cook shellfish to an internal temperature of 145 degrees for at least 15 seconds.

– Recreational harvesters should take extra precautions when gathering oysters during the summer, including putting them on ice or refrigerating them as soon as possible after collecting them.

– Harvest as soon as the tide recedes, avoiding oysters that may have been exposed for unknown periods of time.

– Don’t rinse cooked oysters with seawater.

– Before gathering shellfish, recreational harvesters should check safety information by calling the toll-free hotline at 1-800-562-5632.

The Department of Health has been sending notices to shellfish growers recommending extra precautions during low mid-day tides and warm weather.

Officials close a growing area when vibrio levels are high or when four or more people who eat shellfish from there are sickened within 30 days. As a result, Hammersley Inlet and several parts of Hood Canal, including Dabob Bay and Quilcene Bay, are closed because of high vibrio levels, while Oakland Bay and Totten Inlet growing areas are closed because of recent illnesses.

What’s in crude oil — and how do we use it?

By Kasia Cieplak-Mayr von Baldegg, Grist

The petroleum we pump out of the ground turns into a range of useful things: fuel for all forms of transportation, a key ingredient in plastics, and more. Alexis Madrigal, The Atlantic’s senior technology editor, takes a look at the chemistry of crude oil in the two-minute video above, explaining the process of distilling one barrel, gallon by gallon. Animated by Lindsey Testolin, this clip is part of a six-part video series in The User’s Guide to Energy special report. If this short overview leaves you wanting to know more, check out Kyle Thetford’s more detailed look at the process.

Ice Melt on Steroids: Greenland’s Ice Sheet Being Cooked From Above and Below

Is Mother Earth melting from the inside out?

A new study has brought to light yet another factor that must be added into the complex set of data that is chronicling the melting of the Arctic: The Earth’s molten core may be heating things up from below.

In a paper published on August 11 in the online journal Nature Geosciences, scientists working on an international research initiative called IceGeoHeat at the GFZ German Research Centre for Geosciences in Potsdam, Germany, said they had found a distinct difference in the melt depending on the thickness of the Earth’s crust and upper mantle. Together those two elements form the lithosphere, and in some places on Greenland this has proven to be exceptionally thin, the researchers found. And the thinner the lithosphere, the greater the melt right above it.

“The temperature at the base of the ice, and therefore the current dynamics of the Greenland ice sheet is the result of the interaction between the heat flow from the earth’s interior and the temperature changes associated with glacial cycles,” said study co-author Irina Rogozhina, who initiated IceGeoHeat, in a statement from the research center. “We found areas where the ice melts at the base next to other areas where the base is extremely cold.”

Previous models have assumed that the Greenland ice sheet, which loses 227 gigatonnes of ice annually—contributing 0.7 millimeters to the average 3-mm-per-year sea level change that has been observed worldwide—was melting solely because of air and water temperatures, as well as other surface phenomena, the center’s statement said. The lithosphere was thought to play a minimal role, if any. The new research disputes that notion, the scientists said.

“We have run the model over a simulated period of three million years, and taken into account measurements from ice cores and independent magnetic and seismic data,” said Alexey Petrunin, another lead researcher, in the statement. “Our model calculations are in good agreement with the measurements. Both the thickness of the ice sheet as well as the temperature at its base are depicted very accurately.”

It is just one more factor to be added in when analyzing climate, said the research center, Germany’s main Earth science institute, which studies “the history of the Earth and its characteristics, as well as the processes which occur on its surface and within is interior,” according to its website.

“This effect cannot be neglected when modeling the ice sheet as part of a climate study,” the institute said. “The current climate is influenced by processes that go far back into the history of Earth: The Greenland lithosphere is 2.8 to 1.7 billion years old and is only about 70 to 80 kilometers thick under Central Greenland. It remains to be explored why it is so exceptionally thin. It turns out, however, that the coupling of models of ice dynamics with thermo-mechanical models of the solid earth allows a more accurate view of the processes that are melting the Greenland ice.”

Resurrecting an Estuary: The Qwuloolt Restoration Project

By Monica Brown, Tulalip News

TULALIP – Think of the Puget Sound as one massive estuary, fresh water from the creeks, streams and rivers of the uplands flow into the sound and mix during every tide with seawater from the Pacific Ocean. It’s the perfect recipe for salmon rearing habitat. Then add industry, boat traffic, shoreline development, acid rain and a cocktail of other chemicals. Suddenly, the perfect salmon nursery has become a precarious, dangerous and sometimes deadly environment.

Today, in the Puget Sound, about half of historic estuary land remains. Urban areas such as Seattle and Tacoma have lost nearly all of their estuaries, but cities are not the only places losing this vital habitat; according to the Washington Department of Fish and Wildlife, only about a quarter of the Skagit Bay Estuary remains. Our own home, the Snohomish River watershed, which produces between 25-50% of the Coho salmon in Puget Sound, retains only 17% of its historical estuarial land. With the loss of estuaries and pollution on the rise it’s not a mystery why salmon runs and coastal wildlife are diminishing with every passing year.

An estuary is a partially enclosed coastal body of brackish water, (a mix of seawater and fresh water), with one or more rivers or streams flowing into it that also has a connection to the open sea. The Puget Sound is essentially a huge estuary. It’s the second largest in the U.S., Chesapeake Bay, located on the east coast, is the largest. Brackish waters are where young salmon go to feed, grow and make the transition to the salt water; they’re also an ideal place to hide from both freshwater and saltwater predators. Without suitable estuaries, many young salmon don’t survive long enough to make the journey to the ocean.

Enter Qwuloolt, an estuary located within the Snohomish watershed just south of Marysville. The name, Qwuloolt, is a Lushootseed word meaning “salt marsh.” Because of its rich delta soil, early settlers diked, drained and began using the land for cattle and farming. The levees they established along Ebey Slough, as well as the drainage channels and tide gates, significantly degraded the estuary by preventing the salt water from Puget Sound from mixing with the fresh water from Jones and Allen Creeks.

Luckily, levees can be breached and streams rechanneled. In 1994 Tulalip and a number of national and local partners teamed up to begin the second largest estuary restoration in the Puget Sound. In 2000, Tulalip, along with a group of trustees (NOAA, USFW, NRCS and the Washington State Department of Ecology) began purchasing 400 acres of historic estuary between Ebey Slough and Sunnyside Blvd.

In the years that followed, fish and wetlands biologists, hydrologists and experts in salmon recovery have helped reshape the once vibrant estuary turned farmland. Using historic information about the area, they’ve re-contoured the land to create more natural stream flows and removed invasive species. The final step in rehabilitating the habitat is to break through the earthen dikes and levees and allow the tides to once again mix fresh and salt water, to resurrect an estuary that provides shelter and sustenance for fish, wildlife and people.

Qwuloolt will not only help salmon and wildlife habitat, the restoration protects every resident of the Puget Sound. Estuaries store flood waters and protect inland areas. The plants, microorganisms and soils of the estuary filter water and remove pollutants as well as capture and store carbons for long periods of time.

Qwuloolt is:

Physical stream restoration is a complex part of the project, which actually reroutes 1.5 miles of Jones and Allen creek channels. Scientists used historical and field analyses and aerial photographs to move the creek beds near their historic locations.

Native plants and vegetation that once inhabited the area such as; various grasses, sedges, bulrush, cattails, willow, rose, Sitka spruce, pine, fir, crab apple and alder are replacing non-native invasive species.

Building in stormwater protection consists of creating a 6 ½ acre water runoff storage basin that will be used to manage stormwater runoff from the nearby suburban developments to prevent erosion and filter out pollutants so they don’t flow out of the estuary.

Construction of a setback levee has nearly finished and spans 4,000 feet on the western edge on Qwuloolt. The levee was constructed to protect the adjacent private and commercial property from water overflow once the levee is breached.

Breaching of the existing levee that is located in the south edge of the estuary will begin after the setback reaches construction. The breaching of the levee will allow the saline and fresh water to mix within the 400-acre marsh.

Other estuary restoration projects within the Snohomish River Watershed include; Ebey Slough at 14 acres, 400 acres of Union Slough/Smith Island and 60 acres of Spencer Island. The Qwuloolt Estuary Restoration Project has been a large collaboration between The Tulalip Tribes, local, county, state and federal agencies, private individuals and organizations.
