Dakota Access Pipeline

An overview of multiple legal challenges and protests since the U.S. Army Corps of Engineers considered approving a section of the pipeline near the Standing Rock Sioux Reservation in North Dakota.

After receiving a long-awaited easement, Energy Transfer Partners has begun drilling the last portion of the pipeline. The work should last 60 days, the company says.

In a unanimous vote, Seattle's City Council opted to pull city funds from the banking giant. Hours later, the City Council in Davis, Calif., followed suit.

The U.S. Army Corps of Engineers says it will allow the pipeline to cross under the Missouri River, cutting short an environmental impact assessment and removing the final barrier to construction.

Proponents of the Dakota Access Pipeline say final federal permission for the project is ensured. The Standing Rock Sioux Tribe says the Army must complete an environmental review already underway.

Members of the North Dakota congressional delegation say the acting secretary of the army has ordered the Corps of Engineers to proceed with an easement needed to complete the pipeline.

The projects will need to be approved through the Federal Energy Regulatory Commission, but a resignation will leave that five-person panel with just two members — too few for a quorum.

Opponents of the Dakota Access and Keystone XL pipelines say that President Trump's new executive memo is a disappointment. But it's one that they have been gearing up for.

President Trump indicated that potential deals between the pipeline companies and the federal government would be renegotiated, with the goal of allowing construction to move forward.
