Gessner, Suite 630 Houston TX 77074 NOTICE OF AMENDMENT VIA ELECTRONIC MAIL TO: randy.lentz@oneok.com February 11, 2026 Randy Lentz Executive Vice President and Chief Operating Officer Enlink Processing Services, LLC 100 West Fifth Street Tulsa, OK 74103 CPF 4-2026-006-NOA Dear Mr. Lentz: From July 9 to November 10, 2024, 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.), inspected Enlink Processing Services, LLC’s (Enlink) operations and maintenance procedures. As a result of the inspection, PHMSA has identified the apparent inadequacies found within Enlink’s plans or procedures. The items inspected and the inadequacies are described below: 1. § 195.402 Procedural manual for operations, maintenance, and emergencies. (a) . . . . (c) Maintenance and normal operations. The manual required by paragraph (a) of this section must include procedures for the following to provide safety during maintenance and normal operations: (1) . . . . (15) Implementing the applicable control room management procedures required by § 195.446. § 195.446 Control room management. (a) . . . . (c) Provide adequate information. Each operator must provide its controllers with the information, tools, processes and procedures necessary for the controllers to carry out the roles and responsibilities the operator has defined by performing each of the following: (1) . . . . (3) Test and verify an internal communication plan to provide adequate means for manual operation of the pipeline safely, at least once each calendar year, but at intervals not to exceed 15 months; Enlink’s written procedures were inadequate to provide for the safe operation of a pipeline facility in accordance with § 195.402(c)(15). Specifically, Enlink’s Pipeline Internal Communications Plan (05/25/2022) (ICP) failed to include adequate procedures to test and verify an internal communication plan to provide adequate means for manual operation of the pipeline safely, at least once each calendar year, but at intervals not to exceed 15 months in accordance with § 195.446(c)(3). Enlink’s ICP also fails to give adequate guidance on operating a pipeline facility during a SCADA outage. Therefore, PHMSA proposes that Enlink must revise its ICP to include procedures to test and verify an internal communication plan to provide adequate means for manual operation of the pipeline safely, at least once each calendar year, but at intervals not to exceed 15 months, and include adequate guidance on operating a pipeline facility during a SCADA outage. 2. § 195.452 Pipeline integrity management in high consequence areas. (a) . . . . (b) What program and practices must operators use to manage pipeline integrity? Each operator of a pipeline covered by this section must: (1) Develop a written integrity management program that addresses the risks on each segment of pipeline in the first column of the following table no later than the date in the second column: (c) . . . . (i) What preventive and mitigative measures must an operator take to protect the high consequence area? (1) . . . . (3) Leak detection. An operator must have a means to detect leaks on its pipeline system. An operator must evaluate the capability of its leak detection means and modify, as necessary, to protect the high consequence area. An operator’s evaluation must, at least, consider, the following factors—length and size of the pipeline, type of product carried, the pipeline’s proximity to the high consequence area, the swiftness of leak detection, location of nearest response personnel, leak history, and risk assessment results. 2 Enlink’s written procedures were inadequate to provide for the safe operation of a pipeline facility in accordance with § 195.452(i)(3). Specifically, Enlink’s Hazardous Liquid Integrity Management Plan, V-6.0, section 8.9 (12/08/2023) (HL IMP) lacks sufficient detail to evaluate the capability of its leak detection means and to modify as necessary to protect the high consequence area. Section 8.9 merely references the regulation and states that Form 107 will provide more details without explaining how its process considers all of the required factors in § 195.452(i)(3), as well as other relevant factors. Therefore, PHMSA proposes that Enlink must revise its HL IMP to include how its leak detection evaluation process considers all of the required factors in § 195.452(i)(3).
