12023046NOA_Notice of Amendment_10312023_(22-233293)_text.pdf, page 1Official PDFNOTICE OF AMENDMENT OVERNIGHT EXPRESS DELIVERY October 31, 2023 Ms. Tina Faraca President and Executive Vice President, US Natural Gas Pipelines ANR Pipeline Company 700 Louisiana Street Houston, Texas 77002 CPF 1-2023-046-NOA Dear Ms. Faraca: From March 14 to November 3, 2022, a representative of the Pipeline and Hazardous Materials Safety Administration (PHMSA) pursuant to Chapter 601 of 49 United States Code (U.S.C.) inspected ANR Pipeline Co’s (ANR) procedures for maintenance and normal operations as part of an integrated inspection of ANR’s pipeline system identified by PHMSA as inspection system #1168. As a result of the inspection, PHMSA has identified the apparent inadequacy found within ANR’s plans or procedures. The item inspected and the inadequacy is described below: 1. 49 C.F.R. § 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) Operating, maintaining, and repairing the pipeline in accordance with each of the requirements of this subpart and Subpart M of this part. ANR’s manual of written procedures for operating and maintaining its pipeline in accordance with requirements of Subpart M of 49 CFR Part 192 were inadequate to assure safe operation of a pipeline facility. Specifically, ANR’s maintenance procedures for inspecting and testing relief devices pursuant to §§ 192.731, 192.739, and 192.743 failed to include provisions for inspecting and testing each pressure relieving device in a compressor station at the required intervals not exceeding 15 months, but at least once each calendar year. During the inspection, PHMSA requested ANR’s procedures regarding testing and inspection of relief#

12023046NOA_Notice of Amendment_10312023_(22-233293)_text.pdf, page 2devices. ANR provided the following documents as its Operations and Maintenance Manual (O&M) and supplements to its O&M: • 192.739 Pressure Limiting and Reg Stations - Inspect and Test (O&M) • 192.743 Pressure Limiting and Reg Sta - Capacity of Relief Devices (O&M) • TEC-ME-OPP-G_Overpressure_Protection_Commentary_US (Presented by ANR as supporting document, but unreferenced in O&M) • Safety_Relief_Valve_Inspection_USGO_US – TC Energy Work Task Package (Referenced in O&M) Section 192.731(a) requires, in part, that “. . . each pressure relieving device in a compressor station must be inspected and tested in accordance with §§192.739 and 192.743 . . .” (emphasis added). In reviewing “Table 2-4: Test and Inspection Frequencies” in the ANR document titled TEC-ME-OPP- G_Overpressure_Protection_Commentary_US, ANR incorrectly lists safety relief valves at its compressor stations as being in “non-OPP service” and/or not being subject to the requirements of applicable sections of Part 192. The relief valves are installed to protect pressure vessels, pipe and fittings that are located between equipment isolating valves These relief valves under consideration are over-pressure protection devices that are designed and installed to protect gas transportation equipment from a scenario of thermal expansion of natural gas and natural gas liquids that could over pressure pipeline transportation equipment and/or its connected pipe and fittings when subjected to heat due to exposure to sun or fire. ANR fails to subject these certain relief valves designed and installed to protect transportation pipeline equipment to the inspection and testing frequencies required by the applicable sections of Part 192 listed above. As such, and by way of ANR declassifying relief valves that are subject to PHMSA jurisdiction under § 192.731(a)1, ANR failed to follow the §§ 192.7392 and 192.7433 inspection and testing frequencies listed in its O&M procedures titled 192.739 Pressure Limiting and Reg Stations - Inspect and Test, and 192.743 Pressure Limiting and Reg Sta - Capacity of Relief Devices. Therefore, ANR’s procedures required by § 192.605(b)(1) were inadequate. ANR must revise its procedures to address the issues noted above and to properly classify its pipeline transportation equipment safety relief valves. Response to this Notice This Notice is provided pursuant to 49 U.S.C. § 60108(a) and 49 C.F.R. § 190.206.

Nothing in this Agreement alters PHMSA’s right of access, entry, inspection, and information gathering or PHMSA’s authority to bring enforcement actions against Respondent pursuant to the Federal pipeline safety laws, the regulations and orders issued thereunder, or any other provision of Federal or State law. 7. For all transfers of ownership or operating responsibility of Respondent’s pipeline system referenced herein, Respondent will provide a copy of this Agreement to the prospective transferee at least 30 days prior to such transfer. Respondent will provide written notice of the transfer to the Director no later than 60 days after the transfer occurs. 8. This Agreement does not waive or modify any Federal, State, or local laws or regulations that are applicable to Respondent’s pipeline systems. This Agreement is not a permit, or a modification of any permit, under any Federal, State, or local laws or regulations. Respondent remains responsible for achieving and maintaining compliance with all applicable Federal, State, and local laws, regulations and permits. 9. This Agreement does not create rights in, or grant any cause of action to, any third party not party to this Agreement. The U.S. Department of Transportation is not liable for any injuries or damages to persons or property arising from acts or omissions of Respondent or its officers, employees, or agents carrying out the work required by this Agreement. Respondent agrees to hold harmless the U.S. Department of Transportation, its officers, employees, agents, and representatives from any and all causes of action arising from any acts or omissions of Respondent or its contractors in carrying out any work required by this Agreement. 10. Except as set forth herein, this Agreement does not constitute a finding of violation of any other federal law or regulation and may not be used in any civil proceeding of any kind as evidence or proof of any fact, fault or liability, or as evidence of a violation of any law, rule, regulation, or requirement, except in a proceeding to enforce the provisions of this Agreement or in future PHMSA enforcement actions. II. Finding of Violation: A. 1-2023-047-NOPV 11. Item 1 - 49 CFR § 192.707(a)(2): The Notice alleged ANR failed to place and maintain as close as practical pipeline markers described by § 192.707(d) over each buried main and transmission line wherever necessary to identify the location of the transmission line or main to reduce the possibility of damage or interference. Specifically, the Notice alleged that Respondent failed to install line markers on Unit #s 2002, 1062, and 1052, located in Kentucky, Tennessee, and Mississippi, respectively. Respondent contested the allegation of violation as alleged in the Notice, but, for purposes of settlement, has agreed to accept the finding of violation. As such, PHMSA finds a violation of 49 CFR § 192.707(a)(2). 12. Item 1 will be considered by PHMSA as a prior offense in any future PHMSA enforcement action taken against Respondent for the five-year period following the Effective Date of this Agreement.#

Item 2 - 49 CFR § 192.731(a): With respect to Item 2 of the Notice, the Parties agree that this Item should be withdrawn following review of the facts and circumstances surrounding the use of the relief devices referred to in the NOPV. Because this Item is withdrawn, it will not constitute a finding of violation for any purpose, and no further action by Respondent is necessary with respect to this Item. As such, the allegation of violation for Item 2 and the proposed compliance order associated with this Item are withdrawn. B. 1-2023-046-NOA 14. Item 1 - 49 CFR § 192.605(b)(1): With respect to Item 1 of the NOA, the Parties agree that this Item should be withdrawn following review of the facts and circumstances surrounding the use of the relief devices referred to the NOA. Because this Item is withdrawn, no further action by Respondent is necessary with respect to this item. As such, the allegation of inadequacy for Item 1 is withdrawn. IV. Compliance Order: A. 1-2023-047-NOPV 15. Item 1: The NOPV proposed certain compliance order actions to address the non- compliance alleged in the NOPV. Respondent contested the Proposed Compliance Order, in part because it installed line markers at the locations referred to in the Proposed Compliance Order in September 2022, prior to issuance of the NOPV, and in March 2024, prior to the hearing, and provided documentation of the installation. PHMSA accepts Respondent’s records regarding the installation of the line markers, but, because of the passage of time since installation, determines that verification of the continued presence of the line markers is necessary to ensure that Respondent is still in compliance. As such, Respondent agrees to verify that the line markers previously installed remain in the field today. ANR will provide photographic evidence of those line markers to the Director within 90 days of the Effective Date of this Agreement. V. Enforcement: 16. This Agreement is subject to all enforcement authorities available to PHMSA under 49 U.S.C. § 60101, et seq., and 49 CFR Part 190, including administrative civil penalties under 49 U.S.C. § 60122, of up to $272,926 per violation for each day the violation continues and referral of the case to the Attorney General for judicial enforcement, if PHMSA determines that Respondent is not complying with the terms of this Agreement in accordance with the determinations made by the Director, or in accordance with decisions of the Associate Administrator if resolved pursuant to the Dispute Resolution process herein. The maximum civil penalty amounts are adjusted annually for inflation. See 49 CFR § 190.223. All work plans and associated schedules set forth or referenced in Section IV (Compliance Order) are automatically incorporated into this Agreement and are enforceable in the same manner.#

The Director and Respondent will informally attempt to resolve any disputes arising under this Agreement, including any decision of the Director under the terms of Sections IV (Compliance Order). If Respondent and the Director are unable to informally resolve the dispute within 15 calendar days after the dispute is first raised, in writing, to the Director, Respondent may submit a written request for a determination resolving the dispute from the Associate Administrator. Such request must be made in writing and provided to the Director, counsel for the Eastern Region, and to the Associate Administrator, no later than 10 calendar days from the 15-day deadline for informal resolution referenced in this paragraph. Along with its request, Respondent must provide the Associate Administrator with all information Respondent believes is relevant to the dispute. Decisions of the Associate Administrator under this paragraph will constitute final agency action. The existence of a dispute and PHMSA’s consideration of matters placed in dispute will not excuse, toll, or suspend any term or timeframe for completion of any work to be performed under this Agreement during the pendency of the dispute resolution process. VII. Effective Date: 18. The term “Effective Date,” as used herein, is the date on which the Consent Order is issued by the Associate Administrator incorporating the terms of this Agreement. VIII. Recordkeeping and Information Disclosure: 19. Unless otherwise required in this Agreement, Respondent agrees to maintain records demonstrating compliance with all requirements of this Agreement for a period of at least five (5) years following completion of all work to be performed, unless a longer period of time is required pursuant to 49 CFR parts 190-199. For any reports, plans, or other deliverables required to be submitted to PHMSA pursuant to this Agreement, Respondent may assert a claim of business confidentiality or other protections applicable to the release of information by PHMSA, covering part or all of the information required to be submitted to PHMSA pursuant to this Agreement in accordance with 49 CFR Part 7. Respondent must mark the claim of confidentiality in writing on each page, and include a statement specifying the grounds for each claim of confidentiality. PHMSA determines release of any information submitted pursuant to this Agreement in accordance with 49 CFR Part 7, the Freedom of Information Act, 5 U.S.C. § 552, DOT and PHMSA policies, and other applicable regulations and Executive Orders. IX. Modification: 20. The terms of this Agreement may be modified by mutual agreement of the Parties. Such modifications must be in writing and signed by both parties. X. Termination: 21. This Agreement will remain in effect until the Compliance Order in Section IV is satisfied, as determined by the Director. The Agreement shall not terminate until the Director#
