The CAO requires SG Resources Mississippi, L.L.C. (SGR or Respondent)1 to take certain necessary corrective actions to protect the public, property, and the environment from the potential hazards associated with the continued operation of its Southern Pines Natural Gas Pipeline System near Leakesville, Mississippi, in Greene County. On February 3, 2026, at approximately 6:30 PM CST, the Southern Pines Natural Gas Pipeline System Line 300 ruptured inside the Southern Pines Energy Center located near Leakesville, Mississippi, in Greene County (hereinafter the “Failure”). The Failure resulted in the separation of the 2-inch liquid extraction line from the Line 300, the formation of a crater within the Southern Pines Energy Center, and the release of a currently undetermined volume of natural gas. Pursuant to 49 U.S.C. § 60117, PHMSA has initiated an investigation of the Failure. The preliminary findings of PHMSA’s ongoing investigation are as follows: 1 SGR is a subsidiary of The Williams Companies, Inc. See SG Resources Mississippi, https://www.gasnom.com/ip/SOUTHERNPINES/ (last accessed February 6, 2026). Preliminary Findings • At approximately 6:30 PM CST on February 3, 2026, the Southern Pines Natural Gas Pipeline System Line 300 ruptured at the Southern Pines Energy Center, an underground natural gas storage facility, near Leakesville, Mississippi, in Greene County. • The Failure resulted in the separation of a 2-inch liquid extraction line from Line 300, the formation of a crater within the Southern Pines Energy Center, and the release of a currently undetermined volume of natural gas. • The event did not impact the integrity of the underground storage, though the entire facility is currently shut-in. The failure happened in a remote location within the Southern Pines Energy Center facility. There were no reported injuries, fatalities, or evacuations, and the escaped gas did not ignite. • SGR attempted to isolate the suspected failed segment of Line 300 using facility valves, but it discovered that one of the valves used to isolate the segment was leaking. In response, SGR isolated the line by closing the upstream and downstream block valves (the Southern Pines Energy Center Valve at mile post 0 and the Midway Valve at mile post 11.75), which are thirteen miles apart, and blew down the section. SGR successfully isolated the failed segment on February 4, 2026. • A recovered portion of the failed pipeline shows indications of internal corrosion that is believed to be microbiologically influenced corrosion. The Southern Pines Energy Center facility has had prior corrosion issues. • The Southern Pines Natural Gas Pipeline System consists of 26.14 miles of natural gas transmission pipeline. The pipeline system includes Line 100 running to the west out of the Southern Pine Energy Center with interconnects to multiple customers, including an interconnect at Ranch Road, and Lines 300 and 400 running to the east out of the Center. Lines 100 and 400 were not disturbed by the Failure; however, SGR also shut in these pipelines. • As a major provider of natural gas along the southern United States, the pipeline system transports natural gas from Mississippi to Alabama. There will be impacts to the supply of commercial natural gas until repairs are made. • At the discharge side of Southern Pines Energy Center, at mile post 0, where the Failure occurred, the Maximum Allowable Operating Pressure (MAOP) reported by Williams personnel is 1480 psig and the Maximum Operating Pressure (MOP) is 1140 psig. • The pipeline was constructed in 2008. The pipeline coating is Fusion Bonded Epoxy (FBE) with an undetermined seam type. Determination of Necessity for Corrective Action Order and Right to Hearing Section 60112 of title 49, United States Code, authorizes PHMSA to determine that a pipeline facility is or would be hazardous to life, property, or the environment and if there is a likelihood of serious harm, to expeditiously order the operator of the facility to take necessary corrective action, including suspended or restricted use of the facility, physical inspection, testing, repair, replacement, or other appropriate action. An order issued expeditiously must provide an opportunity for a hearing as soon as practicable after the order is issued. In deciding whether to issue an order, PHMSA must consider the following, if relevant: (1) the characteristics of the pipe and other equipment used in the pipeline facility, including the age, manufacture, physical properties, and method of manufacturing, constructing, or assembling the equipment; (2) the nature of the material the pipeline facility transports, the corrosive and deteriorative qualities of the material, the sequence in which the material is transported, and the pressure required for transporting the material; (3) the aspects of the area in which the pipeline facility is located, including climatic and geologic conditions and soil characteristics; (4) the proximity of the area in which the facility is located to environmentally sensitive areas; (5) the population density and population and growth patterns of the area in which the pipeline facility is located; (6) any recommendation of the National Transportation Safety Board made under another law; and (7) any other factors PHMSA may consider as appropriate. After evaluating the foregoing preliminary findings of fact, and having considered the characteristics of the pipeline, the nature of the failure, to include the history of corrosion issues at the facility; the hazardous nature of the material transported (natural gas); the existing and potential additional impacts to life, property, or the environment; the still-unknown cause of the Failure; and the possibility of additional failures on the pipeline system; it is hereby determined that continued operation of the Affected Segment, as defined below, without corrective measures is or would be hazardous to life, property, or the environment, and that failure to issue this Order expeditiously would result in the likelihood of serious harm. Accordingly, this Order mandating immediate corrective action is issued expeditiously without prior notice and opportunity for a hearing. The terms and conditions of this Order are effective upon completion of service. Within 10 days of receipt of this Order, Respondent may request a hearing, to be held as soon as practicable, by notifying the Associate Administrator for Pipeline Safety in writing, with a copy to the Director, PHMSA, OPS Southern Region. If a hearing is requested, it will be held in accordance with 49 CFR § 190.211. After receiving and analyzing additional data in the course of this investigation, PHMSA may identify other corrective measures that need to be taken. Respondent will be notified of any additional measures required and, if appropriate, PHMSA will consider a further amended order. To the extent consistent with safety, Respondent will be afforded notice and an opportunity for a hearing prior to the imposition of any additional corrective measures. Corrective Measures Definitions Affected Segment – The “Affected Segment” means the approximately three miles of Line 100 from the mainline valve at Ranch Road to the Midpoint Valves on Lines 300 and 400 (approximate Mile Posts 11.75 and 11.8, respectively). The Affected Segment includes the entire Southern Pines Energy Center and all related facility piping. The Failure – The “Failure” means the rupture of Line 300 that occurred at 6:30 PM CST on February 3, 2026, at the Southern Pines Energy Center, an underground natural gas storage facility, near Leakesville, Mississippi, in Greene County. Isolated Segment – The “Isolated Segment” means the portion of Line 300 from the Southern Pines Energy Center Compressor Station at mile post 0 to the Midpoint Valve at mile post 11.75. Director – The “Director” means the Director, PHMSA, OPS Southern Region. 1. SGR must not operate the Isolated Segment until authorized to do so by the Director. 2. Operating Pressure Restriction. SGR must reduce and maintain a twenty percent (20%) pressure reduction in the actual operating pressure along the entire length of the Affected Segment such that the operating pressure along the Affected Segment will not exceed eighty percent (80%) of the actual operating pressure in effect immediately prior to the Failure on February 3, 2026. a. This pressure restriction is to remain in effect until written approval to increase the pressure or return the pipeline to its pre-failure operating pressure is obtained from the Director. b. Within 15 days of receipt of this Order, SGR must provide the Director the actual operating pressures of each pump/compressor station and each main line pressure regulating station on the Affected Segment at the time of failure and the reduced pressure restriction set-points at these same locations. c. This pressure restriction requires any relevant remote or local alarm limits, software programming set-points or control points, and mechanical over-pressure devices to be adjusted accordingly. d. When determining the pressure restriction set-points, SGR must take into account any in-line inspection (ILI) features or anomalies present in the Affected Segment to provide for continued safe operation while further corrective actions are completed. e. SGR must review the pressure restriction monthly by analyzing the operating pressure data. SGR must take into account any ILI features or anomalies present in the Affected Segment and immediately reduce the operating pressure to maintain the safe operations of the Affected Segment, if warranted by the monthly review. SGR must submit the results of the monthly review to the Director. The results must include, at a minimum, the current discharge set-points (including any additional pressure reductions), and any pressure exceedance at discharge set-points. 3. Restart Plan. Prior to resuming operation of the Isolated Segment, SGR must develop and submit a written Restart Plan to the Director for prior approval. a. The Director may approve the Restart Plan incrementally without approving the entire plan but the Isolated Segment cannot resume operation until the Restart Plan is approved in its entirety. b. Once approved by the Director, the Restart Plan will be incorporated by reference into this Order. c. The Restart Plan must provide for adequate patrolling of the Isolated Segment during the restart process and must include incremental pressure increases during start up, with each increment to be held for at least 2 hours. d. The Restart Plan must include sufficient surveillance of the pipeline during each pressure increment to ensure that no leaks are present when operation of the line resumes. e. The Restart Plan must specify a day-light restart and include advance communications with local emergency response officials. f. The Restart Plan must provide for a review of the Isolated Segment for conditions similar to those of the Failure including a review of construction, operating and maintenance (O&M) and integrity management records such as ILI results, hydrostatic tests, root cause failure analysis of prior failures, aerial and ground patrols, corrosion, cathodic protection, excavations and pipe replacements. SGR must address any findings that require remedial measures to be implemented prior to restart. g. The Restart Plan must also include documentation of the completion of all mandated actions, and a management of change plan to ensure that all procedural modifications are incorporated into SGR’s operations and maintenance procedures manual. h. Prior to restart, SGR must submit to the Director a contingency plan to operate and monitor the Isolated Segment during flooding conditions, including enhanced patrolling and surveillance. 4. Return to Service. After the Director approves the Restart Plan, SGR may return the Isolated Segment to service but the operating pressure must not exceed eighty percent (80%) of the actual operating pressure in effect immediately prior to the Failure on February 3, 2026, in accordance with Item 2 above. 5. Removal of Pressure Restriction. The Director may allow the removal or modification of the pressure restriction upon a written request from SGR demonstrating that restoring the pipeline to its pre-failure operating pressure is justified based on a reliable engineering analysis showing that the pressure increase is safe considering all known defects, anomalies, and operating parameters of the pipeline. 6. The Director may allow the temporary removal or modification of the pressure restrictions upon a written request from SGR demonstrating that temporary mitigative and preventive measures are implemented prior to and during the temporary removal or modification of the pressure restriction. The Director's determination will be based on the Failure cause and provision of evidence that preventative and mitigative actions taken by the operator provide for the safe operation of the Affected Segment during the temporary removal or modification of the pressure restriction. Appeals to determinations of the Director in this regard will be decided by the Associate Administrator for Pipeline Safety. 7. Instrumented Leakage Survey. Within 30 days of receipt of this Order, SGR must perform an aerial or ground instrumented leakage survey of the Affected Segment.

The Southern Pines Energy Center facility has had prior corrosion issues. • The Southern Pines Natural Gas Pipeline System consists of 26.14 miles of natural gas transmission pipeline. The pipeline system includes Line 100 running to the west out of the Southern Pine Energy Center with interconnects to multiple customers, including an interconnect at Ranch Road, and Lines 300 and 400 running to the east out of the Center. Lines 100 and 400 were not disturbed by the Failure; however, SGR also shut in these pipelines. • As a major provider of natural gas along the southern United States, the pipeline system transports natural gas from Mississippi to Alabama. There will be impacts to the supply of commercial natural gas until repairs are made. • At the discharge side of Southern Pines Energy Center, at mile post 0, where the Failure occurred, the Maximum Allowable Operating Pressure (MAOP) reported by Williams personnel is 1480 psig and the Maximum Operating Pressure (MOP) is 1140 psig. • The pipeline was constructed in 2008. The pipeline coating is Fusion Bonded Epoxy (FBE) with an undetermined seam type. Determination of Necessity for Corrective Action Order and Right to Hearing Section 60112 of title 49, United States Code, authorizes PHMSA to determine that a pipeline facility is or would be hazardous to life, property, or the environment and if there is a likelihood of serious harm, to expeditiously order the operator of the facility to take necessary corrective action, including suspended or restricted use of the facility, physical inspection, testing, repair, replacement, or other appropriate action. An order issued expeditiously must provide an opportunity for a hearing as soon as practicable after the order is issued. In deciding whether to issue an order, PHMSA must consider the following, if relevant: (1) the characteristics of the pipe and other equipment used in the pipeline facility, including the age, manufacture, physical properties, and method of manufacturing, constructing, or assembling the equipment; (2) the nature of the material the pipeline facility transports, the corrosive and deteriorative qualities of the material, the sequence in which the material is transported, and the pressure required for transporting the material; (3) the aspects of the area in which the pipeline facility is located, including climatic and geologic conditions and soil characteristics; (4) the proximity of the area in which the facility is located to environmentally sensitive areas; (5) the population density and population and growth patterns of the area in which the pipeline facility is located; (6) any recommendation of the National Transportation Safety Board made under another law; and (7) any other factors PHMSA may consider as appropriate. After evaluating the foregoing preliminary findings of fact, and having considered the characteristics of the pipeline, the nature of the failure, to include the history of corrosion issues at the facility; the hazardous nature of the material transported (natural gas); the existing and potential additional impacts to life, property, or the environment; the still-unknown cause of the Failure; and the possibility of additional failures on the pipeline system; it is hereby determined that continued operation of the Affected Segment, as defined below, without corrective measures is or would be hazardous to life, property, or the environment, and that failure to issue this Order expeditiously would result in the likelihood of serious harm. Accordingly, this Order mandating immediate corrective action is issued expeditiously without prior notice and opportunity for a hearing. The terms and conditions of this Order are effective upon completion of service. Within 10 days of receipt of this Order, Respondent may request a hearing, to be held as soon as practicable, by notifying the Associate Administrator for Pipeline Safety in writing, with a copy to the Director, PHMSA, OPS Southern Region. If a hearing is requested, it will be held in accordance with 49 CFR § 190.211. After receiving and analyzing additional data in the course of this investigation, PHMSA may identify other corrective measures that need to be taken. Respondent will be notified of any additional measures required and, if appropriate, PHMSA will consider a further amended order. To the extent consistent with safety, Respondent will be afforded notice and an opportunity for a hearing prior to the imposition of any additional corrective measures. Corrective Measures Definitions Affected Segment – The “Affected Segment” means the approximately three miles of Line 100 from the mainline valve at Ranch Road to the Midpoint Valves on Lines 300 and 400 (approximate Mile Posts 11.75 and 11.8, respectively). The Affected Segment includes the entire Southern Pines Energy Center and all related facility piping. The Failure – The “Failure” means the rupture of Line 300 that occurred at 6:30 PM CST on February 3, 2026, at the Southern Pines Energy Center, an underground natural gas storage facility, near Leakesville, Mississippi, in Greene County. Isolated Segment – The “Isolated Segment” means the portion of Line 300 from the Southern Pines Energy Center Compressor Station at mile post 0 to the Midpoint Valve at mile post 11.75. Director – The “Director” means the Director, PHMSA, OPS Southern Region. 1. SGR must not operate the Isolated Segment until authorized to do so by the Director. 2. Operating Pressure Restriction. SGR must reduce and maintain a twenty percent (20%) pressure reduction in the actual operating pressure along the entire length of the Affected Segment such that the operating pressure along the Affected Segment will not exceed eighty percent (80%) of the actual operating pressure in effect immediately prior to the Failure on February 3, 2026. a. This pressure restriction is to remain in effect until written approval to increase the pressure or return the pipeline to its pre-failure operating pressure is obtained from the Director. b. Within 15 days of receipt of this Order, SGR must provide the Director the actual operating pressures of each pump/compressor station and each main line pressure regulating station on the Affected Segment at the time of failure and the reduced pressure restriction set-points at these same locations. c. This pressure restriction requires any relevant remote or local alarm limits, software programming set-points or control points, and mechanical over-pressure devices to be adjusted accordingly. d. When determining the pressure restriction set-points, SGR must take into account any in-line inspection (ILI) features or anomalies present in the Affected Segment to provide for continued safe operation while further corrective actions are completed. e. SGR must review the pressure restriction monthly by analyzing the operating pressure data. SGR must take into account any ILI features or anomalies present in the Affected Segment and immediately reduce the operating pressure to maintain the safe operations of the Affected Segment, if warranted by the monthly review. SGR must submit the results of the monthly review to the Director. The results must include, at a minimum, the current discharge set-points (including any additional pressure reductions), and any pressure exceedance at discharge set-points. 3. Restart Plan. Prior to resuming operation of the Isolated Segment, SGR must develop and submit a written Restart Plan to the Director for prior approval. a. The Director may approve the Restart Plan incrementally without approving the entire plan but the Isolated Segment cannot resume operation until the Restart Plan is approved in its entirety. b. Once approved by the Director, the Restart Plan will be incorporated by reference into this Order. c. The Restart Plan must provide for adequate patrolling of the Isolated Segment during the restart process and must include incremental pressure increases during start up, with each increment to be held for at least 2 hours. d. The Restart Plan must include sufficient surveillance of the pipeline during each pressure increment to ensure that no leaks are present when operation of the line resumes. e. The Restart Plan must specify a day-light restart and include advance communications with local emergency response officials. f. The Restart Plan must provide for a review of the Isolated Segment for conditions similar to those of the Failure including a review of construction, operating and maintenance (O&M) and integrity management records such as ILI results, hydrostatic tests, root cause failure analysis of prior failures, aerial and ground patrols, corrosion, cathodic protection, excavations and pipe replacements. SGR must address any findings that require remedial measures to be implemented prior to restart. g. The Restart Plan must also include documentation of the completion of all mandated actions, and a management of change plan to ensure that all procedural modifications are incorporated into SGR’s operations and maintenance procedures manual. h. Prior to restart, SGR must submit to the Director a contingency plan to operate and monitor the Isolated Segment during flooding conditions, including enhanced patrolling and surveillance. 4. Return to Service. After the Director approves the Restart Plan, SGR may return the Isolated Segment to service but the operating pressure must not exceed eighty percent (80%) of the actual operating pressure in effect immediately prior to the Failure on February 3, 2026, in accordance with Item 2 above. 5. Removal of Pressure Restriction. The Director may allow the removal or modification of the pressure restriction upon a written request from SGR demonstrating that restoring the pipeline to its pre-failure operating pressure is justified based on a reliable engineering analysis showing that the pressure increase is safe considering all known defects, anomalies, and operating parameters of the pipeline. 6. The Director may allow the temporary removal or modification of the pressure restrictions upon a written request from SGR demonstrating that temporary mitigative and preventive measures are implemented prior to and during the temporary removal or modification of the pressure restriction. The Director's determination will be based on the Failure cause and provision of evidence that preventative and mitigative actions taken by the operator provide for the safe operation of the Affected Segment during the temporary removal or modification of the pressure restriction. Appeals to determinations of the Director in this regard will be decided by the Associate Administrator for Pipeline Safety. 7. Instrumented Leakage Survey. Within 30 days of receipt of this Order, SGR must perform an aerial or ground instrumented leakage survey of the Affected Segment. SGR must investigate all leak indications and remedy all leaks discovered. SGR must submit documentation of this survey to the Director within 45 days of receipt of this Order. 8. Records Verification. As recommended in PHMSA Advisory Bulletin 2012-06, SGR must verify the records for the Affected Segment to confirm the MAOP. SGR must submit documentation of this record verification to the Director within 45 days of receipt of this Order. 9. Review of Prior Inline Inspection (ILI) Results. Within 30 days of receipt of this Order, SGR must conduct a review of any previous ILI results of the Affected Segment; re-evaluate all ILI results from the past 10 calendar years, to include a review of the ILI vendors' raw data and analysis; and determine whether any features were present in the failed pipe joint and/or any other pipe removed. SGR must also determine if any features with similar characteristics are present elsewhere on the Affected Segment. SGR shall submit documentation of this ILI review to the Director within 45 days of receipt of this Order as follows: a.

Within 90 days following receipt of this Order, SGR must submit a Remedial Work Plan (RWP) to the Director for approval. b. The Director may approve the RWP incrementally without approving the entire RWP. c. Once approved by the Director, the RWP will be incorporated by reference into this Order. d. The RWP must specify the tests, inspections, assessments, evaluations, and remedial measures SGR will use to verify the integrity of the Affected Segment. It must address all known or suspected factors and causes of the Failure identified by, but not limited to, the results of the metallurgical and root cause failure analysis required by this Order. SGR should consider both the risk of another failure and the consequence of another failure to develop a prioritized schedule for RWP related work along the Affected Segment. e. The RWP must include a procedure or process to: i. Identify pipe, both facility and mainline, in the Affected Segment with characteristics similar to the contributing factors identified for the Failure, to include operational or maintenance factors. ii. Gather all data necessary to review the failure history (in service and pressure test failures) of the Affected Segment and to prepare a written report containing all the available information such as the locations, dates, and causes of leaks and failures. iii. Integrate the results of the metallurgical testing, root cause failure analysis, and other corrective actions required by this Order with all relevant pre- existing operational and assessment data for the Affected Segment. Pre- existing operational data includes, but is not limited to, construction, operations, maintenance, testing, repairs, prior metallurgical analyses, and any third-party consultation information. Pre-existing assessment data includes, but is not limited to, ILI tool runs, hydrostatic pressure testing, direct assessments, close interval surveys, and Direct Current Voltage Gradient/Alternating Current Voltage Gradient surveys. iv. Determine if conditions similar to those contributing to the Failure, to include operational or maintenance conditions, are likely to exist elsewhere on the Affected Segment. v. Conduct additional field tests, inspections, assessments, and evaluations to determine whether, and to what extent, the conditions associated with the Failure and other failures from the failure history (see (e)(ii) above) or any other integrity threats are present elsewhere on the Affected Segment. At a minimum, this process must consider all failure causes and specify the use of one or more of the following: 1) ILI tools that are technically appropriate for assessing the pipeline system based on the cause of the Failure and that can reliably detect and identify anomalies, 2) Hydrostatic pressure testing, 3) Close-interval surveys, 4) Cathodic protection surveys, to include interference surveys in coordination with other utilities (e.g. underground utilities, overhead power lines, etc.) in the area, 5) Coating surveys, 6) Stress corrosion cracking surveys, 7) Selective seam corrosion surveys; and, 8) Other tests, inspections, assessments, and evaluations appropriate for the Failure causes. Note: SGR may use the results of previous tests, inspections, assessments, and evaluations if approved by the Director, provided the results of the tests, inspections, assessments, and evaluations are analyzed with regard to the factors known or suspected to have caused the Failure. vi. Describe the inspection and repair criteria SGR will use to prioritize, excavate, evaluate, and repair anomalies, imperfections, and other identified integrity threats. Include a description of how any defects will be graded and a schedule for repairs or replacement. vii. Based on the known history and condition of the Affected Segment describe the methods SGR will use to repair, replace, or take other corrective measures, to include measures to update maintenance or operational procedures that may have been causal factors of the Failure, in order to remediate the conditions associated with the February 3, 2026, pipeline failure and to address other known integrity threats along the Affected Segment. The repair, replacement, or other corrective measures must meet the criteria specified in (e)(vi) above. viii. Implement continuing long-term periodic testing and integrity verification measures to ensure the ongoing safe operation of the Affected Segment considering the results of the analyses, inspections, evaluations, and corrective measures undertaken pursuant to the Order. f. Include a proposed schedule for completion of the RWP. g. SGR must revise the RWP as necessary to incorporate new information obtained during the failure investigation and remedial activities, to incorporate the results of actions undertaken pursuant to this Order, and to incorporate modifications required by the Director. SGR must submit any plan revisions to the Director for prior approval. The Director may approve plan revisions incrementally. Any and all revisions to the RWP after it has been approved and incorporated by reference into this Order will be fully described and documented in the CAO Documentation Report. h. SGR must implement the RWP as it is approved by the Director, including any revisions to the plan. 15. CAO Documentation Report (CDR). SGR must create and revise, as necessary, a CAO Documentation Report (CDR). When SGR has concluded all the items in this Order it will submit the final CDR in its entirety to the Director. This will allow the Director to complete a thorough review of all actions taken by SGR with regards to this Order prior to approving the closure of this Order.
