Line 61 Upgrade Project - Phase 2

Southern Access Stage 2

As part of our ongoing efforts to meet North America’s needs for reliable and secure transportation of petroleum energy supplies, Enbridge is proposing to expand the average annual capacity of Line 61 from 560,000 barrels per day (bpd) to 1.2 million bpd. Enbridge Energy, Limited Partnership (“Enbridge”) is proposing to expand in phases the average annual capacity of our Line 61 Pipeline to an ultimate 1.2 million barrel per day (bpd) design capacity. Line 61 is a 42-inch-diameter crude oil pipeline that spans from Enbridge’s terminal in Superior, Wisconsin, to our Flanagan Terminal near Pontiac, Illinois.

  • Phase 1 will increase the average annual capacity from 400,000 bpd to 560,000 bpd
  • Phase 2 will increase Line 61 to its full 1.2 bpd design capacity

To increase Line 61’s capacity to its full 1.2 million bpd design capacity, Enbridge plans to construct or modify pump stations in the following locations:

  • Wisconsin
    • Station within Superior Terminal in Douglas County
    • Hawthorne Station in Douglas County
    • Minong Station in Douglas County
    • Stone Lake Station in Sawyer County
    • Ladysmith Station in Rusk County
    • Sheldon Station in Chippewa County
    • Owen Station in Clark County
    • Vesper Station in Wood County
    • Marshfield Station in Wood County
    • Adams Station in Adams County
    • Portage Station in Columbia County
    • Waterloo Station in Dane County
    • Delavan Station in Rock County
  • Illinois:
    • Belvidere in Boone County
    • DeKalb in DeKalb County
    • Ottawa in La Salle County

All work will be performed on property that is owned or acquired in fee by Enbridge.  The Project does not require pipeline construction.

Subject to permit and regulatory approvals, construction for Phase 2 would begin in spring 2014, and the pipeline would be operating at a capacity of 1.2 million bpd in 2015.
