Summary

Gulf South Pipeline Company has filed an application with FERC to amend its Petal Storage Capacity Amendment Project. The application seeks to align certificated storage capacities and injection/withdrawal capabilities with the physical capabilities of the Petal Storage Complex in Mississippi. FERC will conduct an environmental review within 90 days.

What changed

Gulf South Pipeline Company, LLC has filed an application with the Federal Energy Regulatory Commission (FERC) requesting authorization to amend its Petal Storage Capacity Amendment Project. The proposed amendments involve reducing the total certificated capacity of the Petal Storage Complex from 46.008 Bcf to 41.774 Bcf, with specific reductions for Cavern 6 and Cavern 12A. Additionally, Gulf South seeks to decrease the certificated injection capability from 1,738 MMscf/d to approximately 1,661 MMscf/d and the withdrawal capability from 2,495 MMscf/d to approximately 2,130 MMscf/d. The company also requests reaffirmation of its market-based rate authority.

Regulated entities, particularly those involved in natural gas storage and transportation, should be aware of this application as it pertains to amendments in certificated capacities and operational capabilities. While no direct compliance deadline for external parties is stated, FERC staff will complete an environmental review within 90 days of the notice, which may lead to further procedural steps. Interested parties can review the full application on the FERC eLibrary and may submit comments or concerns. The primary implication is the potential adjustment of operational parameters for a significant natural gas storage facility.

Take notice that on February 26, 2026, Gulf South Pipeline Company, LLC (Gulf South), 9 Greenway Plaza, Suite 2800, Houston,
Texas 77046, filed an application under section(s) 7(b) and 7(c) of the Natural Gas Act (NGA) and Part 157 of the Commission's

the storage capacities of Caverns 6 and 12A and the certificated injection and withdrawal capability at Gulf South's existing
Petal Gas Storage Field (Petal Storage Complex) located in Forrest County, Mississippi. The purpose of the Project is that
the certificated capacity parameters align with the actual physical capabilities of the Petal Storage Complex. Specifically,
Gulf South is proposing to amend the total certificated capacity of the Petal Storage Complex from 46.008 billion cubic feet
(Bcf) to 41.774 Bcf, and to update its certificated capacity for Cavern 6 from 6.5 Bcf to 3.636 Bcf and for Cavern 12A from
9.75 Bcf to 8.38 Bcf. Also, Gulf South is requesting to reduce the certificated injection capability from 1,738 million standard
cubic feet per day (MMscf/d) to approximately 1,661 MMscf/d, and the withdrawal capability from 2,495 MMscf/d to approximately
2,130 MMscf/d. Gulf South requests the Commission to reaffirm its determination that Gulf South is authorized to charge market-based
rates, all as more fully set forth in the application which is on file with the Commission and open for public inspection.

For instructions on how to intervene, see below.

Interventions

Any person, which includes individuals, organizations, businesses, municipalities, and other entities, (6) has the option to file a motion to intervene in this proceeding. Only intervenors have the right to request rehearing of Commission
orders issued in this proceeding and to subsequently challenge the Commission's orders in the U.S. Circuit Courts of Appeal.

To intervene, you must submit a motion to intervene to the Commission in accordance with Rule 214 of the Commission's Rules
of Practice and Procedure (7) and the regulations under the NGA (8) by the intervention deadline for the project, which is 5:00 p.m. Eastern Time on April 2, 2026. As described further in Rule
214, your motion to intervene must state, to the extent known, your position regarding the proceeding, as well as your interest
in the proceeding. For an individual, this could include your status as a landowner, ratepayer, resident of an impacted community,
or recreationist. You do not need to have property directly impacted by the project in order to intervene. For more information
about motions to intervene, refer to the FERC website at https://www.ferc.gov/resources/guides/how-to/intervene.asp.

There are two ways to submit your motion to intervene. In both instances, please reference the Project docket number CP26-117-000
in your submission.

(1) You may file your motion to intervene by using the Commission's eFiling feature, which is located on the Commission's

be asked to select the type of filing you are making; first select “General” and then select “Intervention.” The eFiling feature
includes a document-less intervention option; for more information, visit https://www.ferc.gov/docs-filing/efiling/document-less-intervention.pdf.; or

(2) You can file a paper copy of your motion to intervene, along with three copies, by mailing the documents to the address

Protests and motions to intervene must be served on the applicant either by mail at: Juan Eligio Jr., Director, Regulatory
Affairs, Gulf South Pipeline Company, LLC, 9 Greenway Plaza, Suite 2800, Houston, Texas 77046 or by email (with a link to

information for parties can be downloaded from the service list at the eService link on FERC Online. Service can be via email
with a link to the document.

All timely, unopposed (9) motions to intervene are automatically granted by operation of Rule 214(c)(1). (10) Motions to intervene that are filed after the intervention deadline are untimely, and may be denied. Any late-filed motion
to intervene must show good cause for being late and must explain why the time limitation should be waived and provide justification
by reference to factors set forth in Rule 214(d) of the Commission's Rules and Regulations. (11) A person obtaining party status will be placed on the service list maintained by the Secretary of the Commission and will
receive copies (paper or electronic) of all documents filed by the applicant and by all other parties.

Tracking the Proceeding

Throughout the proceeding, additional information about the project will be available from OPP at (202) 502-6595 or on the
FERC website at www.ferc.gov using the “eLibrary” link as described above. The eLibrary link also provides access to the texts of all formal documents
