The U.S. Army Corps of Engineers approved the construction of the Dakota Access Pipeline on Tuesday, paving the way for an infrastructure project that has been surrounded by protest and controversy.

Robert Speer, the acting secretary of the Army, announced the decision to Congress, saying he was ready to offer the pipeline’s owner a 30-year easement on a disputed patch of land.

In the decision, Speer said he would halt the preparation of an environmental impact statement meant to assess the effects of the pipeline, adding that he had sufficient information to support approval. The pipeline had already passed environmental review and a federal judge found for the pipeline after the Standing Rock Sioux Tribe flied a lawsuit, based on the tribe’s water supply and sacred lands, against it before then-President Obama halted the project last November. No part of the proposed route goes through tribal lands.

The easement will allow for the completion of the last mile and a half of the 1,172-mile project, connecting oil production areas in North Dakota to a crude oil terminal near Patoka, Ill. The pipeline is owned by Energy Transfer Partners. In a statement, Sen. Heidi Heitkamp, D-N.D., said, “Today’s announcement by the U.S. Army Corps of Engineers brings this issue one step closer to final resolution — and delivers the certainty and clarity I’ve been demanding.”
