The Southern Access pipeline features a 36-inch diameter and 42-inch diameter crude oil pipeline that transports crude oil from western Canada to the Midwest, United States.

Expansion Project

In 2015, the Illinois Extension Pipeline Company, L.L.C. (IEPC) -- a joint venture in which Enbridge Energy Company, Inc. owns 65% and Lincoln Pipeline, L.L.C., a subsidiary of Marathon Pipeline Company, Inc. owns 35% -- completed construction of the Southern Access Extension (SAX) Pipeline Project.[2] The 168-mile long, 24-inch-diameter pipeline transports crude oil from Enbridge's Flanagan Terminal near Pontiac, Illinois to a crude oil terminal near Patoka, Illinois.[2] The SAX pipeline project was cost more than $900 million.[2]

The SAX project is part of Enbridge's Lakehead System Mainline Expansion, which will increase the pipeline capacity to 1,200,000 barrels per day upon the addition of additional pumping horsepower; however, the in-service date of this phase of the SAX was delayed until 2019.[3]

According to the Enbridge’s Energy Infrastructure Assets report, as of June 2020 the expansion project was operational.[4]

Expansion Project Location

The pipeline expansion runs through Illinois.[5]

A number of landowners along the Southern Access pipeline's original proposed route opposed the project. At least one Illinois landowner reportedly refused an Enbridge offer to $6,000 per acre for a permanent easement, plus $1,8000 per acre for a temporary right-of-way during construction.[6] Enbridge did successfully negotiate contracts with all 321 Wisconsin landowners in the pipeline's route, and at least 560 Illinois landowners.[6] Enbridge sought authority from the Illinois Commerce Commission to condemn land along the pipeline's route in cases in which landowners refused to permit an easement.[6]

Environmental Impact

In 2009, Enbridge affiliate Enbridge Energy Partners agreed to a $1.1 million settlement in a lawsuit after the Wisconsin Department of Natural Resources cited nearly 100 violations of laws protecting the environment during the course of constructing the pipeline.[7]
