DES MOINES, Iowa (AP) — State officials have revoked a stop-work order on the Bakken oil pipeline where it crosses American Indian land that includes burial grounds.

Iowa Department of Natural Resources granted Texas-based Dakota Access LLC an amendment to its sovereign lands construction permit.

Department spokesman Kevin Baskins says the pipeline will be located about 85 feet underground in the Big Sioux River Wildlife Management Area by using special equipment rather than digging a trench for a route.

State Archaeologist John Doershuk said in an email last week to department director Chuck Gipp that the proposed method is a satisfactory avoidance procedure.

Indigenous Environmental Network organizer Dallas Goldtooth says his organization opposes the department’s decision to allow the pipeline to be constructed in the area.
