Coal bed methane project worries ranchers, irrigatorsApril 1,2003By Steve Miller, West River Editor http://www.rapidcityjournal.com Some South Dakota and Wyoming ranchers and irrigators are worried about an oil company's proposal to dump millions of gallons of water from Wyoming coal bed methane wells into the Cheyenne River drainage. They say the water will be high in sodium bicarbonate and other salts, which could ruin irrigated land and harm aquatic life, streamside vegetation and wildlife. They also say the higher water levels would disrupt river crossings for landowners. ConocoPhillips, the company proposing the coal bed methane project, disputes the allegations, saying the water it will discharge has lower salt levels than the water already in the Cheyenne. ConocoPhillips wants to drill 200-300 new coal bed methane wells in the southern part of the Powder River Basin southwest of Gillette, Wyo. To get to the methane, drillers must first pump out water from on top of the coal seam. That water must be disposed of. If the state of Wyoming approves a permit, the company will develop the wells and pipe the water from the Pumpkin Buttes area near Wright, about 20 miles south to Antelope Creek, which feeds into the Cheyenne River, Conoco-Phillips project manager David Jones of Houston said. Water would be held in two reservoirs before being dumped into Antelope Creek. Construction wouldn't begin for at least a year, Jones said. About 100 wells are operating in the Cheyenne River basin. Federal energy officials estimate the entire basin between Gillette and Buffalo has the potential for 39,000 new wells. The Wyoming Department of Environmental Quality is now sifting through public comments on the ConocoPhillips proposal. Department director John Corra will decide on the permit, in April at the earliest. His decision can be appealed to the Wyoming Environmental Quality Council. Argument over impact Assessments vary widely on the impact of coal bed methane water on the Cheyenne River, the plants and animals in and around it and on irrigation land. Tom Cook, a former chemistry professor from Black Hills State University who lives on the Cheyenne River near Hot Springs, says the discharge's high sodium content would devastate irrigated land, the river and surrounding land. "I believe this is going to kill this place off," Cook said. Keith Andersen, who ranches on the Cheyenne River on both sides of the Wyoming-South Dakota border, is also concerned about the quality of discharge water that would be dumped into the Cheyenne. Most of his irrigated land is on the Wyoming side. Normally, irrigators would welcome more water, Andersen, who is also chairman of the Fall River Conservation District board, said. However, the high level of sodium bicarbonate relative to calcium and magnesium in coal bed methane water can make clay soil impervious to water, ruining it for irrigation, Andersen said. "It turns it into hardpan." ConocoPhillips' Jones said sodium bicarbonate and other salts would be diluted during irrigation periods, keeping the sodium absorption rate (SAR) within permitted levels. Jones says the discharge water will contain lower salt content than the water in the river as it enters South Dakota now. "Effectively, we'll be reducing the salt content on an average basis," Jones said. All of the discharged water will meet state standards for downstream uses, company officials say. Angostura Irrigation District Manager Mick Jenniges said he is counting on the U.S. Bureau of Reclamation, which owns Angostura Reservoir and the water in it, and the South Dakota Department of Environment and Natural Resources, to make sure the coal bed methane water isn't harmful. "I am trusting that they are making sure the water is going to be suitable for crops." The Bureau of Reclamation isn't aware of any negative effects from the current coal bed methane discharge, either in the Cheyenne River drainage or the Belle Fourche River drainage, according to BOR civil engineer Curt Anderson in Rapid City. Anderson said the bureau hasn't heard from many people worried about the discharge into either drainage. In fact, Pat Trask, chairman of the Cheyenne River Water Users Association, favors the project. Trask ranches on the Cheyenne River near Elm Springs and uses river water for irrigation. He agrees with the company's assessment that the coal bed methane discharge water will be of higher quality than the water currently in the river. "It will be a net benefit to the Lower Cheyenne," he said. Trask also said he appreciates the willingness of ConocoPhillips to work with landowners to try to arbitrate problems. Belle Fourche Irrigation District members are concerned about the discharge, but tests in the inlet have found water to be within limits so far, according to district manager Renel Hall-Beck. Wyoming coal bed methane wells have been discharging water into the Belle Fourche for several years. DENR satisfied The South Dakota Department of Environment and Natural Resources voiced its concerns to Wyoming officials about an earlier ConocoPhillips proposal to discharge up to 57 cfs of coal bed methane into the Cheyenne drainage. As a result of that and other comments, Phillips withdrew its permit request and submitted its latest proposal â?" to release 35.7 cfs. The department's main concerns were damage to irrigation land, increased stream flows and increased sediment in the water, according to Jeanne Goodman, DENR water-quality program administrator DENR is satisfied with the changes in Phillips' revised permit request, Goodman said. "We are happy with the changes they made, but we are going to do our own monitoring," she said. Any discharge will have to meet South Dakota standards, Kelli Buscher, engineering director for the water-quality progra, said. The department has received many queries from South Dakota residents on the latest Phillips proposal, Buscher said. Cook said the department's acceptance of the new permit is a big mistake. He said coal bed methane water already has damaged the Tongue River in Montana. Coal bed methane water discharged into the Tongue River from Fidelity Exploration and Production at Decker, Mont., has doubled the SAR levels in the Tongue, according to rancher Art Hayes of Birney, Mont., head of the Tongue River Water Users Association. The 75-member association has sued the state of Montana to stop the discharge. Hayes said not much irrigation land has been damaged yet, except for a few spots on the lower end of the Tongue. But he said the company's high-sodium discharge water has killed cottonwood trees around the Tongue River Reservoir. He fears the impact of the discharge on the Tongue is just beginning. Like Cook, Hayes says sodium from high SAR discharge water accumulates in soils. "It would be criminal for South Dakota to allow the company to discharge water," he said. Wyoming opposition The Niobrara County (Wyoming) Conservation District, based in Lusk, also opposes Phillips' proposal. Discharge of high salinity coal bed methane water would hurt eight or 10 irrigators plus 30 to 40 ranchers and other landowners along the Cheyenne River in Niobrara County alone, Heidi Sturman, water-quality technician for the district, said. One of the district's objections is that Phillips plans to drill into the deeper Big George coal seam between Gillette and Buffalo. "The deeper you go, the worse the water is," Sturman said. She said the reduction of flow in the new proposal to 35.7 cfs would not be enough to mitigate the damage. She said the Cheyenne River at low flow already has a high sodium absorption ratio, so irrigators wait for storms or other runoff to dilute the sodium befo re using water for irrigation. But if the new water coming in also has high SAR, it could damage irrigated land, Sturman said. "This water is extremely high in sodium and higher in SAR than the irrigation water they use now," Sturman said. "Also, you can end up with a buildup of salts down at the root zone, so plants can't function properly." Rancher Andersen said the SAR would be 15 at the discharge point, above the level of 10 that South Dakota allows. ConocoPhillips' Jones said, however, that the Wyoming permit would require the company to further dilute the water during irrigation periods, bringing the SAR down to 10. Sturman said the increased water would also damage aquatic life in Antelope Creek and the Cheyenne River, and damage plants along the streams as well as wildlife. The higher flows also could ruin river crossings for cattle and for landowners. She said ice jams could cause spillovers of the high-salinity water, which could damage surrounding soil and plants. Jones said ConocoPhillips would try to work with landowners to compensate them for access problems caused by higher water. But Sturman said she knew of no positive comments on the Phillips proposal from within Wyoming. "There is no economic benefit here, from any of this. If we have to start dealing with problems with the discharge, that will be long term," she said. Deciding the permit The comment period ended Feb. 17 on the proposed permit. Wyoming Department of Environmental Quality staffers are sifting through those comments now, Gary Beach, administrator of DEQ's water-quality division, said. Beach said the department would look at existing uses of the water downstream, including irrigation, before a decision on the permit is made. "We cannot authorize releases of water from the industry that would adversely affect current uses of water in the natural system," Beach said. Both the sodium absorption ratio and the total salinity will be taken into account before deciding on the permit, he said. "In my mind, they're both a concern," Beach said, although the SAR could have longer-term impact on irrigated land. "If you break down soil structure, you'll never reclaim them," Beach said. High total salinity doesn't affect the soil as much but it hurts plant growth, he said. However, that could be treated with better quality water. Beach said DEQ told Phillips more than a year ago that it would have trouble approving its original request to release 57 cfs into Antelope Creek. He said 35.7 cfs would reduce the concentration of salinity downstream. "The question that still exists is, when you get down to the base flow and levels they use to irrigate, are you still going to have concentrations too high?" Beach said. But he said not all of the water released would reach far downstream. He said about .1 cfs is lost per mile of stream. Water discharged into Antelope Creek would have to travel more than 100 stream miles before reaching South Dakota, Beach said. Higher flows Beach said he doubted whether any of the current discharge from the coal bed methane wells into the Cheyenne River drainage is reaching South Dakota. However, some irrigators and ranchers say parts of the river are running now that didn't before, despite drought, Sturman said. Keith Andersen, who grew up on his ranch on the South Dakota-Wyoming border, says the river has continued to flow there during the past three winters, something that it does not normally do. He said the company told him the peak flows under the new permit would raise the river 10 inches through his ranch. And he worries that, because of evaporation, the water will have a higher salt content the closer it gets to South Dakota. Andersen and Sturman would like more study of the river flows and water quality before a permit is approved. They say they don't oppose energy development. "The challenge is to find a better way to handle the water," Andersen said. ConocoPhillips' Jones, however, says reasonable predictions can be made with U.S. Geological Service data on the river going back 70 years. And he said the permit would require the company to gather baseline data before beginning construction on the pipeline. He also said ConocoPhillips is willing to look at alternative uses for the water if it is economically feasible for the company. Cook, who holds a doctorate in chemistry, says his calculations show that the additional permitted discharge, along with the existing permits, would allow dumping of up to 40 million gallons of water a day into the Cheyenne River. He says the water would bring at least 600,000 pounds per day of sodium bicarbonate (baking soda). Sodium bicarbonate interferes with fish reproduction, and coal bed methane water dramatically reduces aquatic bug counts, Cook says. The new permit would allow ConocoPhillips to dump about 23 million gallons a day at peak flows. "And guess where it's coming?" Cook said. "It's going to come down the Cheyenne since Montana is trying to close it off." Cook says Montana has limited the amount of coal bed methane water it will accept, so Conoco-Phillips is looking to dump its water into the Cheyenne heading east to South Dakota. Beach said Wyoming's DEQ is cautiously approving permits to dump into the Powder River because Wyoming has an interim agreement with the state of Montana not to degrade the Powder River or the Tongue River, both of which flow into Montana. He said after Montana settles on specific numeric standards, another agreement will be worked out. Beach said the DEQ is more concerned about concentrations of salts rather than the total amounts. Cook says he doesn't trust Wyoming officials to protect the river drainages, either by rejecting the permit or by monitoring the allowed discharges. "I h ave a very bad feeling about this. I think this may be the biggest environmental economic war that we're going to see in the western states." Contact Steve Miller at 394-8417 or steve.miller@rapidcityjournal.com |
