TEPPCO says it has entered into a letter of intent with an affiliate of Enterprise Products Partners to form a joint venture to construct an additional expansion of the Jonah Gas Gathering System.

The Jonah system, located in the Green River Basin of southwestern Wyoming, gathers and transports natural gas produced from the prolific Jonah and Pinedale fields to natural gas processing plants and major interstate pipelines that deliver the natural gas to end-use markets.

Construction of the additional expansion project will begin this Spring following completion of the Phase IV expansion, which was scheduled for February. This expansion is expected to be completed in the fourth quarter of 2006, at a cost of approximately $200 million.
