Crews are cleaning up diesel fuel after a pipeline leak north of Aberdeen.
Kim McIntosh with the South Dakota Department of Environment and Natural Resources says officials do not yet know the cause or how much diesel leaked. McIntosh says that the public is not in any danger.
She says NuStar, which owns the pipeline, contacted the state agency Monday night after a drop in pressure was reported in the line. Cleanup started early Tuesday morning and the line was shut down.
