Powder River Basin: Coal on the Move in Wyo. and Mont.
  • Published: January 19th, 2014

  • By Gary Braasch, The Daily Climate
    GILLETTE, Wyo. – The broad high prairie of eastern Wyoming and southern Montana was once the bottom of a shallow sea, a rich subtropical swampland for millions of years. Layers of plants began forming peat beds 60 million years ago, later to be buried and compressed into bituminous coal strata.

    The Missouri River became the dominant stream as the Northern Rockies formed, with tributaries like the Yellowstone, Powder and Cheyenne rivers running north and east to meet it. Their erosion eventually left coal seams only a few feet beneath the land surface of what today is called the Powder River Basin.

    No other coal seam on the planet is so big, so close to the surface, and so cheap to mine, said Thomas Michael Power, a professor emeritus at the University of Montana who studies energy economics.

    A National DebateToday the massive deposits, enough to light the United States almost into the 23rd century, have become the center of a regional – and increasingly national – debate: Should this resource continue to be developed, how will it get to market and what is that market? The coal is so cheap that companies see profit in shipping it west via vast trains, a half-mile or more long, then clear across the Pacific Ocean to meet Asia's seemingly insatiable demand.

    There is also concern over the role coal plays in global warming and health impacts. Coal is the "dirtiest" fossil fuels, emitting mercury, nitrogen oxides, sulfur – and 2.5 tons of carbon dioxide for every ton of ore burned. Natural gas emits about half as much of the greenhouse gas. According to the Energy Information Agency, coal is source of 44 percent of global energy-related CO2 emissions.

    Coal CenterThere's strong history here in the basin. And no shortage of conflict.

    The region has been a western center of the American coal industry since the 19th century. Only after Clean Air Act amendments required lower sulfur levels in 1990 did the Basin's low-sulfur bituminous and subbituminous coal become the dominant U.S. coal for generating electricity, power and heat nationwide.

    This rich grassland was home to herds of bison and native Cheyenne, Crow and Lakota who were forcefully displaced by white pioneers and settlers, who then grazed thousands of head of cattle. Much of this 26,000-square-mile area is still grazed on a combination of private ranches, national grassland administered by the Department of Agriculture, and grazing allotments run by the Bureau of Land Management. BLM also controls the coal, oil and other mineral rights; today that's where the money is.

    The drive to develop coal has increasingly pitted ranchers against mining companies in a fight for water resources. Aquifers, pierced by mines, are draining away. What is sweet summer grassland to a rancher is overburden to be scraped away by a miner. Grazing allotments literally disappear as the U.S. Forest Service declares pasture unavailable due to mining activity.

    "You just have to take a loss," said rancher L.J. Turner from near Wright, Mont. "That 6,000 acres we lost supported our family."

    History also repeats here, though on a different scale.

    Just south of the Basin in Guernsey, Wyoming, one can see pioneer wagon, oxen and foot-worn ruts from the 1830s Oregon Trail, carved two to six feet deep into sandstone.

    Now, for miles to the north into Montana the land is rutted, ripped and stripped by 16 huge open pit coal mines, tracked by railroads carrying the black fuel to power U.S. electricity. And increasingly, it's a landscape punctured by gas and oil wells.

    Quiet Gravel Roads

    I spent a week this fall roaming the landscape, accompanied by environmental health scientist Joan Rothlein, to see where so much of America’s coal comes from and the source of proposed coal exports. Along the main two-lane highway where huge coal and oil industry semi trucks continuously loom in the rear-view, and out on quiet gravel ranch roads where pronghorn antelope graze, we captured some of the people and work of today’s energy boom.

    A ranch on the Little Powder River north of Gillette, Wyo., now shares the land with the recently built Dry Fork Power Plant, generating 385 megawatts of electricity by burning coal from a nearby mine.

    Only eight years ago coal power created more than half U.S. electricity; now it is down to about 37 percent due to the rise of natural gas and global warming concerns.

Under state and federal leases, mines are expanding through the grassland soils and surface rock, spitting it out as piled-up spoils and imperfectly restored land.

    Emissions Limits

    Forty percent of American coal comes from this part of Wyoming and Southern Montana, and almost all of it is burned to generate electricity. Coal burning power plants, according to BLM figures, create 13 percent of U.S. carbon dioxide emissions – more than any other single activity. The coal and power industries now face new Environmental Protection Agency emissions limits.

    Big Trucks, Long TrainsNot much here is small: The trucks are 40 feet long, 20 feet high at the cab and roll on six 11-foot diameter tires. They carry 200 tons of coal, dumping it onto a conveyor that transfers the coal to trains of up to 150 hopper cars.

    Grass grows in a reclaimed mining area north of Wright, Wyo. Coal companies tout the success of reclamation. BLM regulations require performance bonds and say mined areas must be restored to "approximate original contours" with water and habitat in "healthy condition."

    But the Western Organization of Resource Councils, a nonprofit fighting coal development, analyzed BLM reports and found otherwise: "Coal mining has disturbed more than 162,000 acres of land in Wyoming," the group wrote, "but only 4 percent of this land has gained final reclamation status" with full restoration and legal release from the bond.

    Dust from blasting, mine work and heavy truck traffic on gravel roads casts a pall over the landscape. EPA monitoring station data shows worsening air pollution since 1980 as more coal has been mined.

    'Dust Pneumonia'

    Very few people live directly adjacent to the coal mines now, but mines are expanding near the Gillette and Wright areas. On the range near roads and mines, ranchers report young cattle and horses can suffer from "dust pneumonia."

    Rancher L.J. Turner looks after some of his red angus cattle on a pasture he leases from the federal Thunder Basin National Grassland. The success of his herd depends on this rich prairie. But underneath lies a thick seam of coal – and the giant North Antelope Rochelle Mine in the background is gobbling up the prairie to get to it.

    Mining Has PriorityMining has priority among the values of this federal land, so the mine has been permitted to truck off as "overburden" about 6,000 of the 7,500 acres in Turner's original grazing allotment.

    That rich summer grass supported Turner's family. Now there may be harder times ahead.

    Turner, born and raised on this land his family has owned since 1918, points across the 10,000 acre ranch to some of the streams that have dried up in recent years. He blames coal mining.

    Creeks like Antelope Creek dry up in summer now, except for spring holes. Fish, beaver, mink and muskrats are mostly gone.

    "From Antelope Creek north to Gillette all the aquifers are being cut by mines," he said. "Water upstream is draining away."

    'Just Gone'

    Turner says the aquifer lies at about 90-100 feet deep, so when it is sliced open by blasting and power shovels, water collects in bottom of the mines. Some of the water is pumped out, some used for wetting the mine roads or other mine uses.

    But for a rancher, "it's just gone."

    "My biggest concern is water. There's not enough of it now, and it's dirty," said Karen Turner, looking over a map of their ranch and government grassland leases with her husband, L.J. "We drink bottled water because our water smells like hydrogen sulfide, and it didn't used to."

    Along with the encroaching coal mines, many wells for oil and natural gas have been drilled recently and more are being negotiated on and near the ranch. The Turner's gain some income from wells on their land, but they do not own the mineral rights beneath.

    The quiet and traditional ranching life "is gone and not coming back," L.J. Turner said. Ranch hands are hard to find because of the higher-paying oil and coal jobs.

    Their young adult children love the ranch, but "are not enthusiastic about coming back to do battle," including court fights with state authorities over protection of springs and smaller water sources.

    For Karen, the drilling and mining "makes you angry – sick with anger."

    The loading area is a hive of activity at Arch Coal Company's Black Thunder Mine, the second greatest producer but the largest mine in the Powder River Basin. Aerial photos by Skytruth in 2012 showed this mine has dug up and scarred more than 40 square miles – almost the area of San Francisco.

    Black Thunder Mine produced 93 million tons of coal in 2012 and employed 1,635 people.

    Coal cars stage for loading at the Black Thunder Mine near Wright, Wyo. Up to 100 coal trains are loaded daily in the Powder River Basin and leave day and night on railroad tracks bound for more than 200 power plants to the east, south and increasingly, west.

    In the Basin, coal companies have been paying only a dollar a ton to the BLM for coal from federal land leases. Last summer, one bid of 21 cents a ton was rejected by the BLM and another lease offer got no bids.

    Analysts peg the slump to two factors: cheap natural gas and climate change regulations.

    Exports vs. Domestic Need

    Publicly-owned coal is supposed to be sold to the companies at a "fair market price" to meet national energy needs. An Interior Department Inspector General report on Powder River Basin coal in 2013 said that, to the contrary, sale prices have been too low, mine data supplied by the companies has not been independently verified and high export prices for coal not counted in "fair market" calculations.

    Exported coal fetches up to ten times the approximately $10 per ton price paid by domestic end users.

    Coal companies have been courting both export markets in Asia and port officials in Oregon and Washington, hoping to greatly increase coal exports. Peabody Energy's CEO called it "a new era of U.S. exports … to the world's best market for coal."

    Three large Northwest export terminal applications are in the study and permitting process. Expansion could mean 40 trains a day, rather than the two or three now, rumbling the 1,400 miles to the west coast through the environmentally sensitive Columbia River Gorge and blocking traffic in scores of towns along the way.

    According to BNSF studies, from 10,000 to 64,000 pounds of coal dust and chunks are blown and rattled off each mile-long train per 400 mile trip.

    Strong Opposition

    Expansion plans have created strong opposition from some Western leaders and citizens. Lawsuits have been filed against the EPA charging violations of the Clean Water Act from coal along the tracks. Twenty-one environmental groups asked in April for "an immediate moratorium on new coal leasing in the Powder River Basin" on payment, health and climate change grounds.

    In response, the Department of Interior said it already reports greenhouse gas effects from the burning of coal when considering new mines. It also noted ongoing reviews of leasing and pricing programs.

    The Basin now leads the state in oil production. The shale gas and oil is usually extracted by hydraulic fracturing – the injection of water, chemicals and fine sand into wells in the process called fracking – while coal bed methane is released by pumping water out of deep coal strata. Brackish wastewater from wells – called "produced water" – is pumped out on land, reinjected into wells, or pumped into filtering ponds.

    New Regulations

    Wyoming has new regulations starting in March 2014 for energy operators to test fresh water wells and springs within a half mile of drilling sites to monitor any pollution.

    The EPA estimates that each fracked oil well requires two to four million gallons of water. The water comes from aquifers used for drinking water and ranching. Water, already a contentious issue in the West, has become even more so as the gas drilling and coal mining intensifies.

    Could this be the future? An integrated solar photo-voltaic and glass panel on the SW Wyoming Visitor Center near Cheyenne frames a set of mid-sized wind turbines on a hill outside the center.

    The center is an advertisement for Wyoming's potential as a renewable energy leader. But Wyoming lags behind 14 other states in wind power, even though it has the eighth highest potential, according to U.S. Department of Energy figures.

    Wind Power Promise

    To the west of the Powder River Basin, several large new wind farms are being planned, but in November Duke Energy accepted a federal criminal plea agreement to pay $1 million for bird kills at two established turbine arrays.

    The coal and petroleum-rich Powder River Basin also holds wind power promise. The Turners have had three test anemometers on their ranch for more than 6 years. "It's fantastic," Karen Turner said, looking at the wind speed and consistency record. "The capacity factor is 50 percent. Most wind farms are viable at 20 percent."

    But lack of tax credit for renewable energy and other economic factors keep wind from being installed in their area, Turner said.

    In Push For Nuclear Power, Climate Change Concerns Overlooked



    Three years ago the world was reminded of the dangers nuclear energy poses when catastrophe struck Japan at the Fukishima power plant. Since then the gravity of the disaster has grown more evident as cleanup efforts have turned into a debacle. In the last month alone we have seen news of radioactive water leaks at the site, lawsuits from U.S. Navy sailors who responded to the initial disaster and are now developing cancer and ongoing harm to the fishing industry.

    The nuclear industry is often portrayed as a climate-neutral alternative to coal and natural gas. An industry-tied movie called Pandora's Promise, recently featured at Sundance and debuted through Netflix and iTunes, has been promoting this very perspective.

    But nuclear power plants need cooling water, which means they are often situated on shore lines. That makes these plants more vulnerable to the consequences of climate change, such as sea level rise. They are also more at risk of being affected by the ever-growing number and severity of storms tied to climate change, such as Hurricane Sandy.

    Case in point: National Oceanic and Atmospheric Administration researchers recently concluded that a small six-foot-high miniature tsunami that hit near a New Jersey nuclear power plant this summer was not the result of a seismic event (as tsunamis usually are). Instead, the researchers concluded that the surge was caused by a sudden atmospheric pressure change. The nuclear plant, Oyster Creek, did not report any damage. But experts say there was a cautionary lesson on offer: expect the unexpected. Climate change will cause more destructive and seemingly freakish events like this. Emergency planners need to plan for them — especially when the risks are high as is the case with nuclear plants.

    Coal plants are increasingly being retired nationwide. As a result, permit applications for new nuclear power plants have sharply increased for the first time in 30 years. Construction has begun at a handful of plants nationwide. But federal authorities have given little consideration to sea level rise and other climate change impacts. These officials have paid even less attention to the shifting risks associated with the storage of nuclear waste.

    Fukushima: The Catastrophe Continues

    On January 18, workers at the Daiichi nuclear reactor discovered a water leak in the building that houses Reactor 3. That building exploded on March 14, 2011, three days after a 9.0 earthquake and ensuing tsunami. Japanese officials later confirmed that the reactor was one of three at the plant that had melted down.

    Since this summer, steam has repeatedly risen from the reactor. This has spurred concerns about a new meltdown. Officials from Tokyo Electric Power Company (TEPCO) have reassured the public that the steam was likely from rainfall and atmospheric conditions, adding that radiation levels did not rise during the steam events.

    This week, troubles continued at the reactor. TEPCO announced that unlike the steam, a foot-wide water leak on the first floor of the Reactor 3 building carried high temperatures and levels of radioactivity and that the leaking water had likely been used to cool the reactor. Officials said there was no indication the leaking radioactive water had escaped the building. But controlling leaks like these is key to cleanup plans for the stricken reactors and the discovery represented another setback for TEPCO.

    These troubles are the tip of the iceberg. Even if things go as planned, TEPCO officials predict removing the fuel from the plant will take 30 or 40 years. Removing the nuclear fuel from Reactor 4, which was damaged but did not melt down, is expected to consume much of this year, and then the company must confront the much more complex task of removing fuel rods from the three melted reactors. Meanwhile, there are the 400 metric tons of groundwater contaminated every day by radiation from the site, which has forced TEPCO to store 400,000 metric tons of the water in 1,000 rickety storage tanks that have repeatedly leaked, sending radioactive materials into the ocean. Another quake could unleash a massive spill of that radioactive water.

    A Climate-Neutral Fuel?

    Driven by fear of catastrophic climate change, some prominent scientists have begun campaigning for increased reliance on nuclear plants. On November 23 climate and energy scientists James Hansen, Ken Caldeira, Kerry Emanuel and Tom Wigley published an open letter to world leaders calling for increased reliance on nuclear power as a tactic to quickly cut carbon emissions.

    "Global demand for energy is growing rapidly and must continue to grow to provide the needs of developing economies," they wrote. "At the same time, the need to sharply reduce greenhouse gas emissions is becoming ever clearer."

    But the climate harm that has already been done makes reliance on nuclear power more dangerous.

    In a report published October 23, the Intergovernmental Panel on Climate Change more than tripled its 2007 projections for sea level rise, predicting a rise of up to 82 centimeters by 2100.

    This means worse effects from storms. "With sea-level rise, it’s not the slow creeping that’s the problem," John Perkins, Evergreen State College environmental historian, told Climate Central. "It’s the fact that with storms and other extreme events you push more water farther inland, which can create real problems."

    In 2011, a paper Perkins published in the journal Energy Policy found that direct sea level rise during the expected life of U.S. nuclear plants poses little risk, as the plants are sufficiently elevated. But these higher seas would lead to storm surges during Category 4 or 5 hurricanes that would completely submerge the nuclear power plants. And if the IPCC’s newly tripled predictions hold true, the storm surge from hurricanes could prove even more devastating to American nuclear plants.

    Little Planning, Big Risks

    Meanwhile, some say U.S. nuclear regulators have been burying their heads in the sand. On Dec. 19, the Columbia Center for Climate Change Law faulted the Nuclear Regulatory Commission for failing to take storm surges into account. "[M]erely accounting for a static sea level rise does not consider risks due to more frequent and severe flooding," they wrote in public comments surrounding plans to store spent nuclear waste at operating power plants.

    "Sea level rise takes the current level of vulnerability and multiplies it," Senator Jeff Bingaman, Democrat from New Mexico explained in a 2012 congressional hearing. "When sea levels rise, the storm surge associated with extreme storms gets even worse, and even an average storm can have above-average consequences." Though experts at the hearing called for the Nuclear Regulatory Commission to study the risks, only six senators attended that hearing, and experts say planning remains insufficient.

    As of 2011, the U.S. had 104 nuclear reactors at 65 plants nationwide, a quarter of which were designed like the Fukushima Daiichi plant. Many of these plants are located near densely populated coastal areas.

    In Florida, two nuclear plants are located on barrier islands, including the Turkey Point plant, which survived a hit from Hurricane Andrew in 1992. Engineers at Turkey Point had enough warning to shut down the plant’s reactor before the hurricane hit, but the resulting damage left the plant dependent on diesel generators to run the cooling pumps for five days. At Fukushima, flooding from the tsunami wiped out cooling systems.

    More recently, Hurricane Sandy prompted the shutdown of several nuclear reactors along the densely-populated East Coast. Though damage to nuclear power plants from the storm was minimal, experts warn that climate change makes storms like Sandy and Andrew far more likely to recur. In September, the National Oceanic and Atmospheric Administration released a study that warned the probability of a storm like Sandy recurring had doubled since 1950. If carbon emissions continue on their current path, the federal researchers warned, Sandy-level storm surges could become a yearly occurrence by 2050.

    " We learned that they (the region’s nuclear power plants) just barely made it through safely during Sandy," Klaus Jacob, a seismologist at Columbia University, told Climate Central after the storm, "but that does not imply that future storms, when combined with continued SLR (sea level rise), could not cause serious problems."
