BISMARCK, N.D.—After months of protests by the Standing Rock Sioux and other Native Americans, a federal judge denied the tribe’s request to stop construction of the four-state, $3.8 billion Dakota Access Pipeline (DAPL). But the federal government quickly stepped in Friday by stopping work on one section and asking the pipeline company to do the same on a larger 40-mile swath. Here’s a look at the planned pipeline and the ongoing protests:

After Fiery Train Derailments, a Massive Pipeline Planned

Owned by Dallas-based Energy Transfer Partners, the $3.8 billion, 1,172-mile project would carry nearly a half-million barrels of crude oil daily from North Dakota’s oil fields through South Dakota and Iowa to an existing pipeline in Patoka, Illinois, where shippers can access Midwest and Gulf Coast markets. Announced in 2014, supporters said the pipeline would create more markets and reduce truck and oil train traffic—the latter of which has been a growing concern after a spate of fiery derailments of trains carrying North Dakota crude.

Tribes Sue Over Water, Sacred Sites

The Standing Rock Sioux’s lawsuit challenged the U.S. Army Corps of Engineers’ decision to grant permits at more than 200 water crossings. Filed on behalf of the tribe by environmental group Earthjustice, the suit says the project violates several federal laws, including the National Historic Preservation Act, and will disturb sacred sites outside of the 2.3-million acre reservation.

The lawsuit alleged that the pipeline, which would be placed less than a mile upstream of the reservation, could impact drinking water for more than 8,000 tribal members and millions who rely on it downstream. A separate lawsuit filed Thursday by the Yankton Sioux tribe in South Dakota challenges the same thing. ETP says the pipeline includes safeguards such as leak detection equipment, and workers monitoring the pipeline remotely in Texas could close block valves on it within three minutes if a breach is detected.

Protesters Set Up Camp, a Movement Grows

Since April, there’s been a tribal protest—held mostly by members of the Standing Rock Sioux —at the confluence of the Cannonball and Missouri rivers. It’s grown considerably, as they’ve been joined by other American Indians and other, non-Native Americans from across the country, including celebrities such as “Divergent” actress Shailene Woodley. Nearly 40 have been arrested as the protest has grown in size, including Standing Rock Sioux Tribal Chairman David Archambault II. None of the arrests stemmed from Saturday’s confrontation between protesters and construction workers.
