The proposed pipeline is currently targeted to deliver into existing NGL infrastructure in the Chicago area including the Aux Sable facility, which processes gas from Alliance pipeline and fractionates NGLs from various supply sources. Additional NGL fractionation capacity is available at the plant.

Stephen Letwin, executive vice president of gas transportation & international at Enbridge, said: “The Chicago area has substantial markets to accommodate the large volumes of NGLs that are expected to be associated with future Marcellus production. Other NGL markets, including Ontario, can also be accessed from Chicago utilizing existing infrastructure.

“This proposed pipeline will provide an excellent long term solution for development of this promising play, as it will enable NGL production to grow unconstrained for many years.”

The company said that it will develop, construct, own and operate the planned NGL pipeline. The company is currently evaluating various routing and market alternatives and anticipates moving forward with an open season in the second quarter 2010.
