Project Overview

In the response to the market demand for increased pipeline capacity, Enbridge Pipelines (Toledo) Inc. ("Enbridge Toledo") developed the Line 79 Pipeline System Project for the transportation of crude oil and petroleum in the state of Michigan. This new pipeline system – designated as Line 79 -- originates near the city of Stockbridge, Michigan and extends to the east and south, to terminate at a new meter station site near the city of Romulus, Michigan, as shown on the Project overview map. Line 79 consists of approximately 64 miles of new and existing pipeline, which includes the following:

• Construction of approximately 35 miles of new 20-inch pipeline from Stockbridge to Freedom Junction;
• Leasing of approximately 29 miles of existing 16-inch Wolverine pipeline from Freedom Junction to Romulus; and
• Installation of certain new station facilities at the existing Stockbridge and Freedom Junction Stations, and at a new meter station site near the city of Romulus.

The rising demand for increased pipeline capacity is a direct result of certain expansion or efficiency projects by refineries in Michigan and Ohio. These refinery projects, which are scheduled for completion this year, will require additional supplies of heavy crude oil and periodic supplies of light crude oil. Line 79 is designed to handle an average flow rate of 80,000 barrels per day, and will provide a cost-effective transportation solution to meet the energy needs of Michigan and regional consumers. The estimated Project cost is $190 million. The projected in-service date of the Line 79 Project is early 2013. A Michigan PSC application was filed in early January 2012.
