Inergy Midstream will conduct a non-binding open season for firm wheeling service on an extension of its Tres Palacios gas storage facility pipeline header system.

The proposed pipeline extension will create a new point of interconnection at the tailgate of Copano Energy’s Houston Central gas processing plant in Colorado County, Texas.

The Tres Palacios header extension project is expected to include approximately 20 miles of newly constructed lateral piping, additional compression, and interconnect facilities.

Once complete, the Tres header project will enable shippers to move gas along 60 miles of header pipe with access to a combination of 10 interstate and intrastate pipelines and the Tres Palacios storage facility.

Additionally, shippers will have access to the Tres Palacios Hub point.

Copano’s Houston Central Plant currently provides 700mmcf/d of processing capacity and 22,000 barrels per day of fractionation capacity and is being modified and expanded to handle rich natural gas from the Eagle Ford Shale play.

The anticipated in-service date for the pipeline extension project is the summer of 2012.
