MACKINAW CITY, Mich. – A company that ships oil through the Great Lakes pledged Thursday to keep heavy crude out of a pipeline in northern Michigan.
Enbridge Energy already doesn't transport heavy crude in the Straits of Mackinac. The deal signed with state officials preserves the status quo and requires a 180-day notice if changes are proposed.
