          - [Docket Nos. CP09-110-000;CP07-4-002]

                    On April 7, 2009, Mississippi Hub, LLC (MS Hub), pursuant to section 7(c) of the Natural Gas Act (NGA), for authorization to expand the MS HUB Gas Storage Project (Expansion) previously certificated in CP07-4-000,                     *et al.*                     on February 15, 2007, as amended, in Covington, Jefferson Davis, and Simpson Counties, Mississippi. MS Hub proposes to increase the total capacity of each of its two authorized caverns by 2.38 Billion cubic feet (Bcf) (1.5 Bcf working gas and 0.88 Bcf cushion gas); increase the maximum injection and withdrawal rate of the storage facility; add four 7,700 horsepower (hp) compressor units in lieu of three 5,000 hp compressor units previously authorized; and, construct 14.2 miles of 24-inch diameter pipeline and 22.6 miles of 30-inch diameter pipeline interconnects. MS Hub requests a finding that after the Expansion, the storage project's operation will not exercise market power so that market-based rates may continue to be charged for these services.                

Questions concerning this application may be directed to William Rapp, Liberty Gas Storage, 101 Ash Street, San Diego, CA 92101, at (619) 699-5050.

On September 15, 2008, the Commission staff granted MS Hub's request to utilize the Pre-filing Process and assigned Docket No. PF08-29-000 to staff activities involving the Expansion. Now, as of the filing of this application on April 7, 2009, the Pre-filing Process for this project has ended. From this time forward, these proceedings will be conducted in the Dockets noted in the caption to this Notice.

Pursuant to section 157.9 of the Commission's rules, 18 CFR 157.9, within 90 days of this Notice the Commission staff will either: Complete its environmental assessment (EA) and place it into the Commission's public record (eLibrary) for this proceeding; or issue a Notice of Schedule for Environmental Review. If a Notice of Schedule for Environmental Review is issued, it will indicate, among other milestones, the anticipated date for the Commission staff's issuance of the final environmental impact statement (FEIS) or EA for this proposal. The filing of the EA in the Commission's public record for this proceeding or the issuance of a Notice of Schedule for Environmental Review will serve to notify federal and state agencies of the timing for the completion of all necessary reviews, and the subsequent need to complete all federal authorizations within 90 days of the date of issuance of the Commission staff's FEIS or EA.

There are two ways to become involved in the Commission's review of this project. First, any person wishing to obtain legal status by becoming a party to the proceedings for this project should, on or before the comment date stated below, file with the Federal Energy Regulatory Commission, 888 First Street, NE., Washington, DC 20426, a motion to intervene in accordance with the requirements of the Commission's Rules of Practice and Procedure (18 CFR 385.214 or 385.211) and the Regulations under the NGA (18 CFR 157.10). A person obtaining party status will be placed on the service list maintained by the Secretary of the Commission and will receive copies of all documents filed by the applicant and by all other parties. A party must submit 14 copies of filings made with the Commission and must mail a copy to the applicant and to every other party in the proceeding. Only parties to the proceeding can ask for court review of Commission orders in the proceeding.

However, a person does not have to intervene in order to have comments considered. The second way to participate is by filing with the Secretary of the Commission, as soon as possible, an original and two copies of comments in support of or in opposition to this project. The Commission will consider these comments in determining the appropriate action to be taken, but the filing of a comment alone will not serve to make the filer a party to the proceeding. The Commission's rules require that persons filing comments in opposition to the project provide copies of their protests only to the party or parties directly involved in the protest.

                    The Commission strongly encourages electronic filings of comments, protests and interventions in lieu of paper using the “eFiling” link at                     *http://www.ferc.gov.*                     Persons unable to file electronically should submit an original and 14 copies of the protest or intervention to the Federal Energy regulatory Commission, 888 First Street, NE., Washington, DC 20426.                

                    This filing is accessible on-line at                     *http://www.ferc.gov,*                     using the “eLibrary” link and is available for review in the Commission's Public Reference Room in Washington, DC. There is an “eSubscription” link on the Web site that enables subscribers to receive e-mail notification when a document is added to a subscribed docket(s). For assistance with any FERC Online service, please e-mail                     *FERCOnlineSupport@ferc.gov,*                     or call (866) 208-3676 (toll free). For TTY, call (202) 502-8659.                

*Comment Date:*                     5 p.m. Eastern Time on May 14, 2009.                

Kimberly D. Bose,

Secretary.
