MINOT, N.D. (AP) — A Houston-based petroleum company is proposing a pipeline that would transport North Dakota crude to Superior, Wis.

Enbridge officials say the Sandpiper Pipeline would cover more than 500 miles and could transport about 225,000 barrels per day. The company's current capacity in North Dakota is 275,000 barrels per day.

The pipeline would run from the Beaver Lodge area south of Tioga to the main Enbridge terminal in Superior.

Bob Steede, general manager of Enbridge Pipelines North Dakota, says the pipeline would expand export capacity and increase market opportunities.

Steede says the pipeline would be the company's largest project in North Dakota. If approved, the earliest it could go into service would be late 2015.

Enbridge operates about 50,000 miles of pipelines in North America.
