Atmos Energy Subsidiary Files FERC Request for Louisiana Gas Storage Facility

Business Wire, Feb 5, 2008

DALLAS -- Atmos Energy Corporation (NYSE: ATO) announced today that Atmos Pipeline and Storage, LLC, which is owned by Atmos Energy Holdings, Inc., a wholly-owned subsidiary of Atmos Energy, has submitted a pre-filing request with the Federal Energy Regulatory Commission (FERC) to construct and operate a salt-cavern gas storage project in Franklin Parish, Louisiana.

The proposed development would initially create three 5 billion cubic feet (Bcf) caverns for a total of 15 Bcf of working gas storage, with six-turn injection and withdrawal capabilities. Pending regulatory approval, the first cavern is projected to go into operation by early 2011, with the other two caverns in operation by 2012 and 2014. Based on market demand, four additional storage caverns could potentially be developed.

The storage site is located near Fort Necessity in Franklin Parish, Louisiana, which is approximately one mile from Tennessee Gas Pipeline's 30-inch, 800 Leg and Columbia Gulf's two 30-inch and 36-inch mainlines and approximately eight miles from ANR Pipeline's two 30-inch and 36-inch mainlines. Additionally, it is about six miles from Regency Energy Partners' 30-inch Winnsboro Extension, which is also connected to various other interstate pipelines, including Texas Gas, Gulf South and Trunkline mainlines.

Atmos Pipeline and Storage, LLC, plans to seek market-based rates for the project as part of the FERC filing process.
