The Public Service Commission has approved a plan to convert about 20 miles of 8-inch oil pipeline in McKenzie County from a gathering line to a transmission line.
But that approval came after the company – Belle Fourche – already made the conversion.
Gathering lines are less regulated than transmission lines.
Commissioner Julie Fedorchak said PSC staff will be having some conversations with the company about the right way to make these conversions. She said she wants to deter companies from taking this approach. That could lead to financial penalties.
