BISMARCK, N.D. (AP) — The company building the $3.8 billion Dakota Access oil pipeline says in a court filing that it opposes the Standing Rock Sioux tribe’s request for a temporary work stoppage in North Dakota.

The tribe wants a federal judge to halt construction in the southern part of the state to prevent the destruction of sacred and culturally significant sites. The request came after Saturday’s skirmish between pipeline workers and protesters.

A hearing is scheduled Tuesday in Washington, D.C.

Attorneys for Energy Transfer Partners filed court documents Tuesday denying that workers have destroyed any cultural sites.

The Army Corps of Engineers said in court documents that said it won’t oppose the tribe’s request in the interest of “preserving peace.”

The judge is weighing a broader challenge to federal permits granted for the pipeline, and has said he’ll rule by Friday.
