Dec 4 The U.S. Army Corps of Engineers has denied an easement for the $3.8 billion Dakota Access Pipeline, according to a statement from the Standing Rock Sioux tribe, which has been protesting the project, saying it could contaminate water supplies.

"Today, the U.S. Army Corps of Engineers announced that it will not be granting the easement to cross Lake Oahe for the proposed Dakota Access Pipeline," the tribe said in a statement. "Instead, the Corps will be undertaking an environmental impact statement to look at possible alternative routes."

The 1,172-mile (1,885-km) Dakota Access Pipeline, owned by Texas-based Energy Transfer Partners LP, is mostly complete, except for a segment planned to run under Lake Oahe, a reservoir formed by a dam on the Missouri River. (Reporting By Ernest Scheyder in North Dakota, Writing by Jessica Resnick-Ault in New York; editing by Diane Craft) </s> CANNON BALL, N.D. — U.S. Army Corps of Engineers said Sunday that it won’t grant an easement for the Dakota Access oil pipeline in southern North Dakota.

The decision is a victory for the several thousand camped near the construction site, who’ve said for months that the four-state, $3.8 billion project would threaten a water source and cultural sites.

The pipeline is largely complete except for the now-blocked segment underneath Lake Oahe, a Missouri River reservoir. According to a news release, Assistant Secretary for Civil Works Jo-Ellen Darcy said her decision was based on the need to “explore alternate routes” for the pipeline’s crossing.

The company constructing the pipeline, Dallas-based Energy Transfer Partners, had said it was unwilling to reroute the project. It and the Morton County Sheriff’s Office, which has done much of the policing of the protests, didn’t have immediate comment.

U.S. Secretary for the Interior Sally Jewell said in a statement that the Corps’ “thoughtful approach … ensures that there will be an in-depth evaluation of alternative routes for the pipeline and a closer look at potential impacts” and “underscores that tribal rights reserved in treaties and federal law, as well as Nation-to-Nation consultation with tribal leaders, are essential components of the analysis to be undertaken in the environmental impact statement going forward.”

The federal government has ordered people to leave the main encampment, which is on Army Corps of Engineers’ land, by Monday. But demonstrators say they’re prepared to stay, and authorities say they won’t forcibly remove them.

Earlier Sunday, an organizer with Veterans Stand for Standing Rock said tribal elders had asked the military veterans not to have confrontations with law enforcement officials, adding the group is there to help out those who’ve dug in against the project.

About 250 veterans gathered about a mile from the Oceti Sakowin, or Seven Council Fires, camp in southern North Dakota for a meeting with organizer Wes Clark Jr., the son of former Democratic presidential candidate Gen. Wesley Clark. The group had said about 2,000 veterans were coming, but it wasn’t clear how many actually arrived.

“We have been asked by the elders not to do direct action,” Wes Clark Jr. said. He then talked about North Dakota authorities’ decision to move away from a key bridge north of the encampment by 4 p.m. Sunday if demonstrators agree to certain conditions, saying the National Guard and law enforcement have armored vehicles and are armed.

“If we come forward, they will attack us,” Clark said. Instead, he told the veterans, “If you see someone who needs help, help them out.”

Authorities said they’ll move from the north end of the Backwater Bridge if protesters stay south of it and come to the bridge only if there is a prearranged meeting. Authorities also asked protesters not to remove barriers on the bridge, which they have said was damaged in the late October conflict that led to several people being hurt, including a serious arm injury.

“The question was asked if we would consider pulling back from the Backwater Bridge,” Cass County Sheriff Paul Laney said in a Saturday news release after a conversation between law enforcement and the group’s organizers, “and the answer is yes! We want this to de-escalate.”

Protesters also are not supposed to walk, ride or fly drones north of the bridge, Laney said. Any violation will “will result in their arrest,” the statement said.

The bridge blockade is something that Standing Rock Sioux tribal chairman Dave Archambault has been asking to be removed, the Bismarck Tribune reports , and something he said he would to talk to Gov. Jack Dalrymple about when they meet in person. A date for that meeting hasn’t been set.

Veterans Stand for Standing Rock’s GoFundMe.com page had raised more than $1 million of its $1.2 million goal by Sunday — money due to go toward food, transportation and supplies. Cars waiting to get into the camp Sunday afternoon were backed up for more than a half-mile.

“People are fighting for something, and I thought they could use my help,” said Navy veteran and Harvard graduate student Art Grayson. The 29-year-old from Cambridge, Massachusetts, flew the first leg of the journey, then rode from Bismarck in the back of a pickup truck. He has finals this week, but told professors, “I’ll see you when I get back.”

Steven Perry, a 66-year-old Vietnam veteran who’s a member of the Little Traverse Bay band of Odawa Indians in Michigan, spoke of one of the protesters’ main concerns: that the pipeline could pollute drinking water. “This is not just a native issue,” he said, “This is an issue for everyone.”

Art Woodson and two other veterans drove 17 hours straight from Flint, Michigan, a city whose lead-tainted water crisis parallels with the tribe’s fight over water, he said.

“We know in Flint that water is in dire need,” the 49-year-old disabled Gulf War Army veteran said. “In North Dakota, they’re trying to force pipes on people. We’re trying to get pipes in Flint for safe water.”

On Monday, some veterans will take part in a prayer ceremony in which they’ll apologize for historical detrimental conduct by the military toward Native Americans and ask for forgiveness, Clark said. He also called the veterans’ presence “about right and wrong and peace and love.” </s> CANNON BALL, N.D. — U.S. Army Corps of Engineers said Sunday that it won't grant an easement for the Dakota Access oil pipeline in southern North Dakota.

ANDREW CULLEN / Reuters </s> Activists have spent months protesting plans to route the $3.8 billion Dakota Access Pipeline beneath a lake near the Standing Rock Sioux reservation, saying the project poses a threat to water resources and sacred Native American sites.

Supplies, including food and building materials, will be blocked from entering the main camp following Governor Jack Dalrymple's signing of an "emergency evacuation" order on Monday, said Maxine Herr, a spokeswoman from the Morton County Sheriff's Department.

"They have deliveries, retailers that are delivering to them - we will turn around any of those services," she said.

The order was effective immediately. As of Tuesday morning, however, no vehicles carrying supplies had been turned back, said Cecily Fong, a spokeswoman for the North DakotaDepartment of Emergency Services.

The building materials intended for the site are a top priority because the camp is not zoned for permanent structures, Fong said. Propane tanks also will be blocked because they have been used in attacks against law enforcement, she said.

A spokeswoman from the Standing Rock Sioux tribe was not immediately available for comment.

The 1,172-mile (1,885 km) pipeline project, owned by Texas-based Energy Transfer Partners LP <ETP.N>, is mostly complete except for a segment planned to run under Lake Oahe, a reservoir formed by a dam on the Missouri River.

Thousands of people are protesting at camps located on U.S. Army Corps of Engineers land,north of the Cannonball River in Cannon Ball, North Dakota. The Sacred Stone camp, which was the original camp established in April, is south of the river on the Standing Rock Sioux reservation.

Opposition to the pipeline has galvanized numerous Native American tribes as well as environmental activists. The movement has been bolstered by social media campaigns and the support of celebrities including actors Mark Ruffalo and Shailene Woodley.

North Dakota officials have issued several requests for additional help from federal law enforcement in light of the demonstrators. However, the U.S. Army Corps of Engineers said on Monday that its order to evacuate the primary protest camp - known as Oceti Sakowin - by Dec. 5 would not include forcibly removing people from the land.

"Those who remain will be considered unauthorized and may be subject to citation under federal, state, or local laws," the Army Corps said, adding that enforcement of the order was up to local authorities. </s> The Dakota Access Pipeline's route takes it over four states and nearly 1,200 miles, from the Bakken oil fields in northwestern North Dakota through South Dakota, Iowa and down to a terminal in Illinois.

But one Missouri River crossing just north of the Standing Rock Sioux Reservation in North Dakota has become the focal point of a fight over how the pipeline's route was analyzed and approved by the federal government.

In legal challenges and public demonstrations, members of the tribe and their supporters have argued that they were not adequately consulted about the route. Running the pipeline under a Missouri River reservoir called Lake Oahe, member say, would jeopardize the primary water source for the reservation, and construction would further damage sacred sites near the lake, violating tribal treaty rights.

After more than six months of legal wrangling, the Trump administration reversed a decision by the Obama administration and announced it is allowing the pipeline company, Energy Transfer Partners, to drill under Lake Oahe and finish building the last section of the pipeline.

Here are some key moments in the fight over the Dakota Access Pipeline.

This story has developed over many months, and this timeline captures only a portion of the newsworthy developments that have occurred, focusing largely on legal and policy decisions.



The U.S. Army Corps of Engineers for the Omaha District publishes a draft of its plan to approve the Dakota Access Pipeline route under the Missouri River.

The Corps opened the plan up to public comments, including comments on environmental and cultural impacts.



The U.S. Army Corps of Engineers office determines that no historic properties will be affected by the pipeline crossing.

A letter from the Corps' senior field archaeologist for the project lists five "recorded cultural sites" within the area that could be affected by construction of the pipeline, and more than 30 others that are thought to be within a 1-mile radius.

The letter supports the determination that "no historic properties will be subject to effect," by the crossing under Lake Oahe, and notes that the Standing Rock Sioux has requested further archaeological survey of the area.



The U.S. government's Advisory Council on Historic Preservation disputes the Corps determination in a letter to the assistant secretary of the Army, citing the need for cooperation with tribal leaders to identify areas of concern to them.

In the letter, the advisory council director asks the Corps to justify its decision.



The U.S. Army Corps of Engineers approves the portion of the Dakota Access Pipeline route that crosses the Missouri River at the Lake Oahe reservoir. The crossing is on Army Corps-controlled land.

The 1,261-page report announcing the approval said of the public review process: "No significant comments remain unresolved."

The Omaha district commander, Col. John Henderson, wrote, "I have evaluated the anticipated environmental, economic, cultural, and social effects, and any cumulative effects" of the river crossing and found it is "not injurious to the public interest."



The Standing Rock Sioux Tribe sues the U.S. Army Corps of Engineers. The tribe alleged that the Corps had failed to adequately consult tribe members before approving the pipeline, and had violated the National Historic Preservation Act when it "effectively authorized construction of the vast majority of the pipeline in and around federally regulated waters without any provision to ensure against destruction to culturally important sites."

"There is a high risk that culturally and historically significant sites will be damaged or destroyed in the absence of an injunction," the tribe wrote in its court filing.



Dakota Access LLC, a subsidiary of the pipeline company Energy Transfer Partners, countersues leaders of the Standing Rock Sioux, alleging that protesters near the Lake Oahe river crossing have "halted construction activities" that had been scheduled to begin five days earlier.

"On Wednesday August 10, 2016, representatives of Dakota Access arrived at the Construction Site and were met with resistance by approximately 15 to 30 individuals ... who were protesting the construction of the Pipeline. By the afternoon, the number of individuals protesting at the Construction Site increased to approximately 100," the company wrote.



The Standing Rock Sioux Tribe issues a statement saying Energy Transfer Partners demolished an area that contained "significant Native artifacts and sacred sites" when construction crews bulldozed a two-mile-long area near the Lake Oahe river crossing and north of the Standing Rock Sioux Reservation.

"I surveyed this land and we confirmed multiple graves and specific prayer sites," the tribe's historic preservation officer, Tim Mentz, said in the statement. "Portions, and possibly complete sites, have been taken out entirely."

And protests in North Dakota turned violent when private security guards clashed with some protesters.

As reporter Amy Sisk of the public radio collaboration Inside Energy said in an NPR Live discussion on Facebook, "What happened is some protesters who've been camped out near this construction area broke through a fence to access this construction site and were met with some private security guards and guard dogs hired by the pipeline company. ... Law enforcement says the protesters attacked the security guards and the dogs." She added that demonstrators said the dogs "actually bit some of the protesters."



U.S. District Judge James Boasberg temporarily halts construction on the portion of the Dakota Access Pipeline that crosses the Missouri River at Lake Oahe, pending a full decision on the tribe's earlier lawsuit against the Army Corps.



North Dakota Gov. Jack Dalrymple activates the North Dakota National Guard to assist local law enforcement that had been monitoring demonstrations. In early December, a spokesperson for the guard told NPR that more than 500 National Guard members were on active duty and that multiple buses and military vehicles had been used to "aid law enforcement."



U.S. District Judge James Boasberg denies the Standing Rock Sioux's request to stop construction. In his decision, he writes that "the United States' relationship with the Indian tribes has been contentious and tragic." But he went on to say that the Army Corps "likely complied" with its obligation to consult the tribe, adding that the tribe "has not shown it will suffer injury that would be prevented by any injunction the Court could issue."

But the Justice Department, the Department of the Army and the Interior Department announced that construction on Army Corps-controlled land near the Lake Oahe river crossing should not proceed — and asked that the pipeline company honor the request — pending further evaluation and consultation with the tribe.



Energy Transfer Partners proceeds with construction despite the request by the three federal agencies that it voluntarily halt activities near the Lake Oahe river crossing. The Morton County Sheriff arrests 27 people demonstrating at the site.



The chairman of the Standing Rock Sioux, Dave Archambault II, sends a letter to then-U.S. Attorney General Loretta Lynch requesting an investigation "to protect civil rights" of protesters, citing the "overall militarization of law enforcement response."



Then-President Obama says in an interview that the U.S Army Corps of Engineers is "examining whether there are ways to reroute this pipeline in a way. So we're going to let it play out for several more weeks and determine whether or not this can be resolved in a way that I think is properly attentive to the traditions of the first Americans."



Law enforcement uses tear gas and sprays water at crowds of demonstrators as the temperature drop below freezing, reports Amy Sisk of Inside Energy.



The U.S. Army Corps of Engineers tells protesters to leave some encampments on federal land by Dec. 5, and North Dakota Gov. Jack Dalrymple follows up with an evacuation order for the area, citing "harsh weather." Nonetheless, many people stay.



The Army Corps halts construction of the Dakota Access Pipeline and says it intends to issue an environmental impact statement with "full public input and analysis" before it approves the river crossing at Lake Oahe.



The Army publishes a notice in the Federal Register saying it is preparing the environmental impact statement and soliciting public comments until Feb. 20, 2017, on whether to grant the easement necessary to cross under Lake Oahe.



President Trump signs an executive memorandum instructing the Army to expedite the review and approval process for the unbuilt section of the Dakota Access Pipeline.



The Army says it has been directed to expedite the review process for the easement request, and that "the Assistant Secretary for the Army Civil Works will make a decision on the pipeline once a full review and analysis is completed in accordance with the [president's] directive."



The U.S. Army Corps of Engineers grants the easement allowing the Dakota Access Pipeline to cross under the Missouri River at Lake Oahe, north of the Standing Rock Sioux Reservation. The Corps also issues a memo saying it intends to terminate the public comment period and rescind its notice of intent to prepare an environmental impact assessment.

The pipeline company immediately began construction near the crossing under Lake Oahe.



The Cheyenne River Sioux tribe asks the U.S. District Court to issue a restraining order to block construction of the final piece of the pipeline. The Standing Rock Sioux Tribe officially joins the request a few days later. Both reservations get their water downstream of the Lake Oahe crossing.



U.S. District Judge James Boasberg denies the tribes' joint motion, noting that oil is not yet flowing under the reservoir. In his decision, Boasberg requires Dakota Access LLC to update the court on Feb. 21, "and every Monday thereafter as to the likely date that oil will begin to flow beneath Lake Oahe."



The Standing Rock Sioux Tribe and Cheyenne River Sioux tribe request a summary judgement against both the Army Corps and Dakota Access LLC, a subsidiary of the pipeline company.

The plaintiffs cite tribal land rights under the 1868 Ft. Laramie Treaty and argue that the Corps decision to grant the easement was "arbitrary, capricious, and contrary to law."



The Corps formally terminates its environmental review in a notice published in the Federal Register.



North Dakota Gov. Doug Burgum sets this date as a deadline for the remaining protesters to leave an encampment on federal land near the area of the pipeline company's construction site. </s> CANNON BALL, N.D. (Reuters) - Activists protesting plans to run an oil pipeline beneath a lake near the Standing Rock Sioux reservation in North Dakota said on Saturday they have no intention of leaving a protest camp after U.S. authorities warned it must be vacated by Dec. 5.

The U.S. Army Corps of Engineers, which manages the federal land where the main camp protesting the Dakota Access pipeline is located, said it would close public access to the area north of the Cannonball River, including to protesters. It said this was partly to protect the general public from violent confrontations between protesters and law enforcement that have occurred in the area.

Those who stay could face prosecution for trespassing, the Corps said in a letter to tribal leaders on Friday.

Organizers told a news conference on Saturday at the main protest site where about 5,000 people are camped that they had no intention of moving.

"We are staying here committed to our prayer," said Dallas Goldtooth, an organizer with the Indigenous Environmental Network. "Forced removal and state oppression? This is nothing new to us as native people."

There are smaller camps on land not subject to the planned restrictions, including an area south of the Cannonball River where the Corps said it was establishing a free-speech zone.

North Dakota Governor Jack Dalrymple, a Republican, on Saturday said he supported the decision and the federal government, which allowed the protesters to become entrenched, must lead in the camp's peaceful closure.

Standing Rock Chairman Dave Archambault said he received notice on Friday about the decision in a letter from Colonel John Henderson, an Army Corps district commander.

Archambault said the best thing the federal government could do for safety is deny the easement for the pipeline. "We have an escalating situation where safety is a concern for everybody."

Archambault said he did not see the letter as a forced eviction and the tribe would continue to exercise its First Amendment rights to free speech. The tribe is working on a location on reservation land should people choose to go there, he said.

"I don't think it will ever be an eviction where forces just come in and push people out," Archambault said.

Demonstrators have protested for months against the $3.8 billion Dakota Access Pipeline, owned by Energy Transfer Partners LP , saying it poses a threat to water resources and sacred Native American sites. The companies say the pipeline would carry Bakken shale oil more cheaply and safely from North Dakota to Illinois en route to U.S. Gulf Coast refineries.

The 1,172-mile (1,885-km) project is mostly complete except for the segment planned to run under Lake Oahe less than half a mile north of Standing Rock.

The Obama administration in September postponed final approval of a permit required to allow tunneling beneath the lake, a move intended to give federal officials more time to consult with tribal leaders. But the delay also led to escalating tensions over the project.

Last weekend, police used water hoses in subfreezing weather in an attempt to disperse about 400 activists near the proposed tunnel excavation site.

Demonstrators plan a march at noon Sunday in Washington, from the Department of Justice to the Washington Monument.
The United States Army Corps of Engineers denies a permit for Energy Transfer Partners planned Dakota Access Pipeline running through North Dakota and will begin exploring alternative routes for the pipeline following weeks of protests.
