Representatives from the Standing Rock Sioux Tribe, Energy Transfer Partners, and the Laborers’ International Union met Wednesday in a congressional hearing on energy infrastructure development. Over the course of the two-hour hearing, the Standing Rock tribe struggled to defend its opposition to the Dakota Access Pipeline.

Chad Harrison, a councilman for the Standing Rock tribe, presented the DAPL project as another instance of the U.S. government seizing tribal land.

“The proposal to build the Dakota Access pipeline across the Tribes’ taken treaty lands, and across the Missouri a half a mile upstream of our Reservation, illustrates the continued historic pattern of abuse,” he said.

Harrison acknowledged that the company attempted to schedule meetings about the pipeline route, but emphasized that this was not a “meaningful consultation.” He urged the committee to pass new legislation requiring tribal consent before future energy infrastructure development or to allow tribes to impose conditions on future projects.

However, he had few answers for the committee when asked about Energy Transfer Partners’ numerous attempts to meet with the tribe about the project. Instead, he stressed that “there has never been a meaningful consultation about where to cross that river.”

Joey Mahmoud, an executive vice president of Energy Transfer Partners, the company building the DAPL, disagreed. In his written testimony Mahmoud reiterated the numerous attempts to consult the tribe made by both the Army Corps of Engineers and Energy Transfer Partners. Unlike the 54 other tribes consulted about the project, the Standing Rock Sioux were unwilling to meet.

Mahmoud’s testimony also revealed that some of the tribe’s demands–particularly one for a government to government consultation on the project–are impossible.

“We are not a government,” Mahmoud said of Energy Transfer Partners. “We don’t have the government-to-government relationship that the tribe was seeking to have that consultation. So there lies the issue… We cannot enter into formal consultation with the tribe to resolve some of the issues that they claim.”

The hearing looked beyond the environmental concerns to the economic benefits of pipeline construction. Finishing DAPL would give states a significant boost in tax revenue. North Dakota would gain $13 million in property taxes each year. South Dakota would collect $13.5 million, Iowa $7 million, and Illinois about $700,000.

The economic benefits would not end there. Construction would provide thousands of additional construction jobs, most of them union positions. Here the testimony exposed how the protests have created a tension between environmentalists and unions, two key Democratic constituencies.

Terry O’Sullivan, president of the Laborers’ International Union of North America, which includes many pipeline workers, expressed frustration with the politically-motivated approval process.

“We have watched with dismay as environmental extremists have distorted the facts, disrupted work sites, harassed our members, and abused the regulatory process to obstruct and delay critically needed projects,” O’Sullivan said. He urged the committee to work to streamline the approval process for future projects.

O’Sullivan’s testimony emphasized that pipeline construction provides middle-class wages for workers with a high school education and trade skills. Halting pipeline construction with extraneous environmental impact surveys means the loss of tax revenue for local communities as well as wages and benefits for workers.

The first half of the hearing did not address pipeline construction, but instead focused on the need to upgrade America’s electric grid. Democratic members of the committee defended energy infrastructure development because of the jobs it would provide. Meanwhile, Republicans on the committee, highlighted the broader economic benefits increased access to energy would provide. Vice Chairman Rep. Joe Barton, R-Texas, however, used his time to emphasize the importance of energy infrastructure development while balancing environmental conservation.

“Energy infrastructure is at the heart of the American economy,” he said, before defending responsible energy infrastructure development. Barton had faith that a balance could be found.

“We have proven that nature can be preserved by balancing growth,” Barton said. “We have to find the proper balance. The sweet spot.”

It’s a good goal, but as cleanup of the camps and legal challenges to the pipeline continue in North Dakota, the sweet spot seems far off.
