MARSHALL, Mich. (AP) — Officials say they have located the pipeline break that caused hundreds of thousands of gallons of oil to spew into a major river in southern Michigan.

An official with the Canadian company which owns the pipeline that leaked oil into the Kalamazoo River confirmed the break's discovery during a news conference Saturday afternoon in Marshall.

Enbridge executive vice president Steve Wuori (WUHR'-ee) says "it is highly unlikely there is any other break in the pipe" other than the one that was exposed.

Calgary, Alberta-based Enbridge Inc. says 820,000 gallons of oil leaked beginning Monday. The U.S. Environmental Protection Agency puts the total at more than 1 million gallons.

Wuori says no oil was leaking from the exposed pipe, and the spill has been contained.
