Business Wire, Sept 26, 2006

KANSAS CITY, Mo. -- Inergy, L.P. (NASDAQ: NRGY) announced today that its regulated subsidiary Central New York Oil And Gas Company, LLC ("CNYOG") has been granted its Section 7(c) Application for Certificate of Public Convenience and Necessity by the Federal Energy Regulatory Commission ("FERC") for the expansion of the Stagecoach natural gas storage facility. The certificate authorizes Inergy to construct and operate the Phase II expansion under market-based rate authority, authorizes market-based rates for its new Interruptible Wheeling Service, and allows for the connection of Stagecoach to the Millennium pipeline project when in service.

The Phase II expansion is expected to add approximately 13 Bcf of working gas storage capacity to the existing facility and is targeted for completion in September of 2007. Inergy has previously announced that it has sold 100% of the available deliverability of the Phase II expansion with a weighted average term of all precedent agreements being in excess of eight years. Phase II drilling has begun, and construction of gathering lines is expected to begin within the next two weeks.

"We are pleased to have achieved this milestone and look forward to the successful construction and operation of the Stagecoach expansion," said John Sherman, President and CEO of Inergy.
