Tallgrass/AGL Resources To Develop Prairie State Pipeline

Tallgrass Development, LP and AGL Resources Inc. concluded the non-binding open season for the proposed Prairie State Pipeline. The system would move natural gas from supply connections in central Illinois to the Chicago Market Center and points in between. Prairie State Pipeline is being jointly developed by Tallgrass and AGL Resources and is expected to have ownership participation by both companies should binding commitments be finalized with interested market participants.
