DENVER — Activists fighting the Dakota Access Pipeline will hold a rally at the University of Denver on Tuesday afternoon.

Organizers said they expect more than 900 people to gather for the rally, which is part of a nationwide day of action against the pipeline.

The event is being held from 4-7 p.m. in the Anderson Academic Common (2150 E. Evans Ave.).

“The Army Corps fast-tracked the Dakota Access Pipeline without proper consultation, and as a result, bulldozers are approaching Standing Rock as we speak,” organizers said in a statement released to the media. “If constructed, the Dakota Access Pipeline would carry fracked oil from North Dakota to Illinois, cutting under the Missouri River less than a mile upstream from the Standing Rock Sioux’s drinking water supply as well as through the Tribe’s sacred and historical land.

“This pipeline is a threat to Native sovereignty and will be a climate disaster, but President Obama has the power to reject the final permit needed to complete construction and permanently stop the project.”

The White House said no final decisions have been made regarding a final approval of the controversial Dakota Access Pipeline.

The rally coincides with a Pipeline Leadership Conference being held on campus. Organizers said some of the pipeline companies attending the conference are funding DAPL.

Three high schools in the metro area helped organize a rally against the Dakota Access Oil Pipeline last weekend. Hundreds of protesters marched in Denver on Saturday night.

“Our main goal is to stop this pipeline because it affects 26 million people downstream including Denver,” East High School student and president of the Native American Club Joi Lynch said. “This widely affects us as well.”

Protesters are concerned about the potential for leaks and contamination but the companies behind the pipeline insist the risks are low.

“Pipelines do leak. It’s rare. I think the chances of this pipeline leaking is extremely remote,” said Kelcy Warren, CEO of Energy Transfer Partners.
