Gessner, Suite 630 Houston TX 77074 VIA ELECTRONIC MAIL TO: maas.hinz@cheniere.com February 12, 2026 Maas Hinz Senior Vice President Operations Sabine Pass LNG, L.P. 845 Texas Avenue, Suite 1250 Houston, TX 77002 CPF 4-2025-055-NOA Dear Mr. Hinz: From July 9 to July 25, 2024, a representative from the Pipeline and Hazardous Materials Safety Administration (PHMSA), pursuant to chapter 601 of 49 United States Code, inspected Sabine Pass LNG, L.P.’s1 (Sabine Pass LNG) procedures for atmospheric corrosion inspection, grading and remediation in Sabine Pass, Texas. As a result of the inspection, Sabine Pass LNG was issued a Notice of Amendment on October 16, 2025, which proposed amendment of its procedures. Sabine Pass LNG submitted its amended procedures on February 2, 2026. My staff has reviewed the amended procedures, and it appears that the recommendations provided during the consultation on this Notice of Amendment have been corrected. Accordingly, this case is now closed and no further action is contemplated with respect to the matters involved in this case. Thank you for your cooperation in this matter.

As a result of the inspection, PHMSA has identified the apparent inadequacies found within Sabine Pass’s plans or procedures. The item inspected and the inadequacy is described below: 1. §193.2605 Maintenance procedures. (a) Each operator shall determine and perform, consistent with generally accepted engineering practice, the periodic inspections or tests needed to meet the applicable requirements of this subpart and to verify that components meet the maintenance standards prescribed by this subpart. (b) Each operator shall follow one or more manuals of written procedures for the maintenance of each component, including any required corrosion control. The procedure must include: (1) The details of the inspections or tests determined under paragraph (a) of this section and their frequency of performance; and (2) A description of other actions necessary to maintain the LNG plant according to the requirements of this subpart. 1 Sabine Pass LNG, L.P. is a subsidiary of Cheniere Energy, Inc.#

42025055NOA_Notice of Amendment_10162025_(24-308459)_text.pdf, page 2Sabine Pass’s written maintenance procedures are inadequate to ensure the safe operation of an LNG facility in accordance with § 193.2605(b). Specifically, Sabine Pass’s procedure External Corrosion Grading Guidelines, Rev. 1 (9/25/2023), is inadequate and requires revision in four areas. First, in Section 3.2, the procedure’s severity criteria do not reference or align with any generally accepted engineering practices or standards. Although the procedure references standards such as ISO 4628-3, API RP 583, API 510, API 570, and API 653 in Section 6.2, none of these are incorporated by reference in § 193.2013 or § 192.7, and none include severity categorizations similar to those defined in Sabine Pass’s procedure. For instance, ISO 4628-3 categorizes rusting into six levels, with four categories addressing corrosion on less than 1% of the surface area, and the most severe ISO classification applying to surfaces with 40%–50% rust, whereas Sabine Pass’s procedure includes examples of cases with 100% corrosion and visible cracking. Second, in Sections 8.0-8.20, the photographic examples provided to illustrate severity conditions are inconsistent with the accompanying written descriptions and, in some instances, are overly vague. For example, Condition A15 includes cracking and heavy corrosion, but the corresponding visual representation illustrates a condition worse than stated. Similarly, Condition A8, which shows a pipe wall fully covered with corrosion pits, is classified only as moderate corrosion. Misalignment between these visual examples and the severity categories worsens the ability of personnel to correctly grade and prioritize corrosion features for repair. Third, the procedure assumes that all severity conditions involve total coating failure and exposed steel surfaces actively undergoing corrosion, and lacks a grading category for pipelines with disbonded, damaged, or otherwise failed coatings. This omission fails to account for the necessity of addressing coating defects, even though such issues are reported during inspections and are critical for corrosion prevention. Fourth, the procedure is inconsistent in its prioritization of repairs according to corrosion severity. While Section 3.2 categorizes conditions A13 through A20 as severe or heavy corrosion, Section 3.3 excludes A13 and A14 from P1 priority repairs. This contradiction weakens the credibility of the repair prioritization process and may delay necessary corrective actions for severe conditions. Overall, the procedure requires significant revision to ensure clarity, consistency, and technical accuracy. Therefore, PHMSA proposes that Sabine Pass revise its procedures to address the concerns described above.
