EnLink provided its response to the\nNotice, and submitted its amended procedures, on September 19, 2025.\nPHMSA has reviewed the amended procedures, and it appears that the inadequacies outlined in\nthis Notice of Amendment have been corrected.\nThis letter is to inform you no further action is necessary and this case is now closed. Thank you\nfor your cooperation.\nSincerely,\nBryan Lethcoe\nDirector, Southwest Region, Office of Pipeline Safety\nPipeline and Hazardous Materials Safety Administration\ncc: Timothy Murphy, Director of AIMS, EnLink Processing Services, LLC,\ntimothy.murphy@enlink.com\nMichael LeBlanc, SVP Operations, EnLink Processing Services, LLC,\nmichael.leblanc@enlink.com\n\n42025046NOA_Notice of Amendment_08202025_(24-296558)_text.pdf\n\nNOTICE OF AMENDMENT\nVIA ELECTRONIC MAIL TO: walter.pinto@enlink.com\nAugust 20, 2025\nWalter Pinto\nExecutive Vice President\nEnLink Processing Services, LLC\n1722 Routh Street Suite 1300\nDallas, Texas 75201\nCPF 4-2025-046-NOA\nDear Mr. Pinto:\nFrom April 16 to October 10, 2024 of the on-site inspection, representatives of the Pipeline and\nHazardous Materials Safety Administration (PHMSA), Office of Pipeline Safety (OPS), pursuant\nto Chapter 601 of 49 United States Code (U.S.C.) inspected EnLink Processing Services, LLC’s\n(EnLink) procedures for operations and maintenance in Dallas, Texas.\nAs a result of the inspection, PHMSA has identified the apparent inadequacies found within\nEnLink’s procedures. The items inspected and the inadequacies are described below:\n1. § 192.605 Procedural manual for operations, maintenance, and emergencies.\n(a) . . . .\n(b) Maintenance and normal operations. The manual required by\nparagraph (a) of this section must include procedures for the\nfollowing, if applicable, to provide safety during maintenance and\noperations.\n(1) Operating, maintaining, and repairing the pipeline in\naccordance with each of the requirements of this subpart and subpart\nM of this part.\n§ 192.710 Transmission lines: Assessments outside of high consequence areas.\n(a) . . . .\n\n\n\n(c) Assessment method. The initial assessments and the\nreassessments required by paragraph (b) of this section must be\ncapable of identifying anomalies and defects associated with each of\nthe threats to which the pipeline segment is susceptible and must be\nperformed using one or more of the following methods:\n(1) . . . .\n(3) Spike hydrostatic pressure test. A spike hydrostatic pressure test\nconducted in accordance with § 192.506. A spike hydrostatic pressure\ntest is appropriate for time-dependent threats such as stress corrosion\ncracking; selective seam weld corrosion; manufacturing and related\ndefects, including defective pipe and pipe seams; and other forms of\ndefect or damage involving cracks or crack-like defects;\nEnLink’s written procedures for conducting operations and maintenance activities were inadequate\nto provide safety during maintenance and operations in accordance with § 192.605(b)(1).\nSpecifically, EnLink’s written manual failed to include procedures for conducting a spike\nhydrostatic pressure test in accordance with § 192.710(c)(3).\nEnLink’s procedure, Gas Integrity Management Plan (rev. 6.0; May 23, 2023) (IMP), table IMP\n9-3 – Assessment Requirements for Transmission Pipelines in HCA’s, Note 4, provides for a spike\nhydrostatic pressure test for time-dependent threats, selective seam weld corrosion, manufacturing\nand related defects, and other forms of defect or damage involving cracks or crack-like defects. In\naddition, EnLink’s procedure, Pressure Testing Standards (Rev. 7.0; May 22, 2018), tables 1\nOnshore Gas Pipelines – Test Requirements, Note 1, provides for the performance of a spike\nhydrostatic test if warranted, and requires a 15-minute test at 100 percent of specified minimum\nyield strength (SMYS) or 1.5 MAOP per § 192.506. However, EnLink’s procedures do not\nincluded detailed procedural steps for performing a spike hydrostatic test in accordance with the\nrequirements in § 192.506. .\nTherefore, PHMSA proposes that EnLink revise its procedures to include specific instructions for\nperforming a spike hydrostatic pressure test in accordance with the requirements in § 192.506.\n2. § 192.605 Procedural manual for operations, maintenance, and emergencies.\n(a) . . . .\n(b) Maintenance and normal operations. The manual required by\nparagraph (a) of this section must include procedures for the\nfollowing, if applicable, to provide safety during maintenance and\noperations.\n(1) Operating, maintaining, and repairing the pipeline in\naccordance with each of the requirements of this subpart and subpart\nM of this part.\n§ 192.710 Transmission lines: Assessments outside of high consequence areas.\n(a) . . . .\n(b) General -\n\n\n\n(1) Initial assessment. An operator must perform initial\nassessments in accordance with this section based on a risk-based\nprioritization schedule and complete initial assessment for all\napplicable pipeline segments no later than July 3, 2034, or as soon as\npracticable but not to exceed 10 years after the pipeline segment first\nmeets the conditions of § 192.710(a) (e.g., due to a change in class\nlocation or the area becomes a moderate consequence area),\nwhichever is later.\nEnLink’s written procedures for conducting operations and maintenance activities were inadequate\nto provide safety during maintenance and operations in accordance with § 192.605(b)(1).\nSpecifically, EnLink’s procedure, Non-HCA Assessments ENL-GOM-0098 (version 3.0; rev. May\n23, 2023), failed to include a risk-based prioritization schedule, including any detailed instructions\nor criteria for developing a risk-based prioritization schedule, for performing initial assessments\non segments outside of HCAs in accordance with § 192.710(b)(1).\n1\nTherefore, PHMSA proposes that EnLink revise its procedures to include detailed instructions for\ndeveloping a risk-based prioritization schedule for performing initial assessments on segments\nsubject to § 192.710(a), in accordance with § 192.710(b).\nResponse to this Notice\nThis Notice is provided pursuant to 49 U.S.C. § 60108(a) and 49 C.F.R. § 190.206.
