    November 28, 2018 Ms. Kimberly Bose Secretary Federal Energy Regulatory Commission 888 First Street, N.E. Washington, D. C. 20426 Re: Southern Natural Gas Company, L.L.C. Docket No. RP19-________________ Annual Storage Cost Reconciliation Mechanism Report Dear Ms. Bose: Enclosed for electronic filing is the Annual Storage Cost Reconciliation Mechanism ("SCRM") report of Southern Natural Gas Company, L.L.C. (“Southern”) made pursuant to Section 14 of the General Terms and Conditions of Southern’s FERC Gas Tariff for the twelve- month period ending October 31, 2018. Southern files the following revised sections to its FERC Gas Tariff to be effective January 1, 2019: Section 2.1, Statement of Rates – FT Contesting, Version 23.0.0 Section 2.1.1, Statement of Rates – FT Settlement, Version 26.0.0 Section 2.2, Statement of Rates – FTNN Contesting, Version 23.0.0 Section 2.2.1, Statement of Rates – FTNN Settlement, Version 24.0.0 Section 2.3, Statement of Rates – IT Contesting, Version 23.0.0 Section 2.3.1, Statement of Rates – IT Settlement, Version 23.0.0 The above revised sections implement a surcharge credit of ($.0011) per Dth for the Storage Cost Reconciliation Mechanism Volumetric Surcharge. This compares to the Storage Cost Reconciliation Mechanism Volumetric Surcharge currently in effect of $.0000. Nature, Basis and Reasons for the Proposed Tariff Changes Section 14.2(a) of the General Terms and Conditions of Southern’s Tariff, which was approved by the Commission’s Order Accepting Settlement, Severing Contesting Parties, Issuing Certificates and Approving Abandonment issued in Docket Nos. RP89-224-012, et al., on September 29, 19951 (“Order”), provides for an annual reconciliation of Southern’s storage gas 1 Southern Natural Gas Company, 72 FERC 61,322 (1995), order on reh’g, 75 FERC 61,046 (1996) Brookwood Office Center 569 Brookwood Village Suite 749 Birmingham, AL 35209 205.325.7410

    Ms. Kimberly Bose, Secretary November 28, 2018 Page 2 costs to reflect differences between the cost to Southern of its storage gas inventory and the amount Southern receives for such gas arising out of (i) the purchase and sale of such gas in order to resolve shipper imbalances and (ii) the purchase and sale of gas as necessary to maintain an appropriate level of storage gas inventory for system management purposes. The Order authorized said procedure to become effective as of November 1, 1993, the date Southern’s Order No. 636 restructuring plan was put into effect. Pursuant to Section 14.2(b) of Southern’s Tariff, Southern established a Storage Cost Reconciliation Deferred Account (“Deferred Account”) to track such storage cost differences as of such date. In Southern's general rate case filed on August 31, 2004 in Docket No. RP04-523, Southern proposed to revise Section 14.2 of its General Terms and Conditions to include supply pooling volumes in the SCRM. On April 29, 2005, Southern filed a comprehensive Settlement in this docket which incorporated Southern's revised SCRM. The Settlement was approved by letter order dated July 13, 2005 in Docket Nos. RP04-523-000 and RP04-523-001. Under Section 14.2(c) of the General Terms and Conditions of Southern’s Tariff, at the end of each twelve-month period after initiating service under Order No. 636 (i.e. twelve months ending October), Southern shall determine whether the balance in the Deferred Account is in excess of $500,000. If so, Southern is required to refund or to surcharge, as appropriate, over the twelve months beginning the following January the portion of the Deferred Account balance representing fixed and realized gains or losses from the purchase and sale of Southern’s storage gas inventory. If the balance is less than or equal to $500,000, the balance is carried forward in the Deferred Account. As specified under Section 14.2(c) of the General Terms and Conditions of Southern's Tariff, such refund or surcharge, applicable during the following twelve-month period beginning in January, is to be determined by dividing the fixed and realized gain or loss by (1) the total quantity received under supply pool balancing agreements in Dth, excluding receipts from CSS or ISS contracts, other supply pool balancing agreements, and PAL points of transactions and (2) the total quantity delivered under rate schedules FT, FT-NN, and IT. As set forth on Sheet 1 of Schedule No. 1, the Balance to be Recovered in the instant filing is ($1,629,719). In accordance with Southern’s tariff and as set forth on Schedule No. 1, Sheet 1, Southern computes the Balance to be Recovered of ($1,629,712) by taking (1) the Balance filed for Recovery in Docket No. RP18-197-000 of $206,203 then subtracting (2) the SCRM surcharge credits received for November 2017 through October 2018 of $125,691, then adding (3) the Realized (Gains)/Losses under Section 14.2(c) for November 2017 through October 2018 of $471,259 and then subtracting (4) the penalty revenue collected during the period November 2017 through October 2018 of $2,181,490. The resulting Balance to be Recoverd of ($1,629,719) is then divided by the 12 months ending October 31, 2018 throughput of 1,439,354,049 to equal a credit surcharge of $(.0011)/DTH proposed to be effective January 1, 2019.
