A natural gas company is seeking commitments to expand a pipeline that runs through North Dakota. : Alliance Pipeline's announcement this week comes as the state's oil and gas regulators are encouraging new infrastructure investment to handle growing volumes of natural gas production, The Bismarck Tribune reported. "Strong customer demand is the driver for this initiative," said Dan Sutherland, Alliance vice president for commercial operations, in a statement. The company receives natural gas from British Columbia, Alberta and North Dakota. It enters North Dakota in Renville County and travels southeast to Richland County.
