42024031NOA_Notice of Amendment_05022024_(23-264807)_text.pdf, page 1Official PDFNOTICE OF AMENDMENT VIA ELECTRONIC MAIL TO: tom.long@energytransfer.com May 2, 2024 Thomas Long Chief Executive Officer Energy Transfer, LP 8111 Westchester Drive, Dallas, Texas 75225 CPF 4-2024-031-NOA Dear Mr. Long: From March 6 to October 17, 2023, a representative of the Pipeline and Hazardous Materials Safety Administration (PHMSA), Office of Pipeline Safety (OPS), pursuant to Chapter 601 of 49 United States Code (U.S.C.) conducted an on-site inspection of Enable Gas Transmission, LLC’s (Enable)1 integrity management plan in Oklahoma City, Oklahoma. As a result of the inspection, PHMSA has identified the apparent inadequacy found within Enable’s plans or procedures. The item inspected and the inadequacy are described below: 1. § 192.605 Procedural manual for operations, maintenance, and emergencies. (a) . . . . (b) Maintenance and normal operations. The manual required by paragraph (a) of this section must include procedures for the following, if applicable, to provide safety during maintenance and operations. (1) . . . . (2) Controlling corrosion in accordance with the operations and maintenance requirements of Subpart I of this part. § 192.493 In-line inspection of pipelines. When conducting in-line inspections of pipelines required by this part, an operator must comply with API STD 1163, ANSI/ASNT ILI– PQ, and NACE SP0102, (incorporated by reference, see § 192.7). 1 Enable Gas Transmission, LLC is a subsidiary of Energy Transfer, LP.#

42024031NOA_Notice of Amendment_05022024_(23-264807)_text.pdf, page 2Assessments may be conducted using tethered or remotely controlled tools, not explicitly discussed in NACE SP0102, provided they comply with those sections of NACE SP0102 that are applicable. Enable’s written procedures for conducting operations and maintenance activities were inadequate to assure the safe operation of a pipeline facility in accordance with § 192.605(b)(2). Specifically, Enable’s Pipeline Integrity Management Plan (Revision No. 17; Dated 05/24/2023) section 7.2.3 and In-Line Inspection Specification – PI-1.3 (Revision Date: 05/25/2022) section 6.1 failed to include in-line inspection (ILI) survey acceptance criteria as required by section 5.1.5 in NACE SP0102 in accordance with § 192.493. Section 5.1.5 in NACE SP0102 requires that operators and ILI vendors develop and agree to a set of ILI survey-acceptance criteria, such as physical damage to sensors after an ILI run, lost sensor channels on data, sensor noise, distance inaccuracy, missed or not recorded features, and velocity overruns, prior to the start of an ILI run. Enable’s procedures failed to include the requirement to develop and agree to a set of survey- acceptance criteria that define when a rerun survey is required in accordance with section 5.1.5 of NACE SP0102. Therefore, Enable’s written procedures for controlling corrosion were inadequate to assure the safe operation of a pipeline facility in accordance with § 192.605(b)(2). Enable must revise its procedures to require the development of ILI survey-acceptance criteria as required by NACE SP0102.
