DES MOINES, Iowa (AP) — The Environmental Protection Agency and two other federal agencies have asked the U.S. Army Corps of Engineers to more carefully review its Dakota Access oil pipeline plan.
The pipeline will cross through Illinois, Iowa, North Dakota and South Dakota. The corps has jurisdiction over portions crossing public waterways including the Missouri and Mississippi rivers.
The EPA, Department of the Interior and Advisory Council on Historic Preservation want the corps to pay closer attention to the impact a spill would have on drinking water.
The corps' draft plan has been criticized for not being thorough enough.
An EPA official says the pipeline's Missouri River crossing poses risks of drinking water contamination for five Native American tribal nations downstream if a leak developed.
A corps spokeswoman says the concerns are under review.
