II. Findings of Violation: 11. Item 1- 49 C.F.R. § 195.446(c)(2): The Notice alleged that Magellan’s point-to- point records were not adequate to demonstrate thoroughness of the verification process between SCADA displays and related field equipment. Specifically, the Notice alleged that Magellan failed to provide documentation to support verification of the alarms presenting at the right set point, with the correct priority, color and alarm description in the alarm log as well as appropriately on subsequent SCADA screens and that there was no indication that the test was completed live or simulated. Respondent does not contest the allegation of violation as alleged in the Notice. As such, PHMSA finds a violation of 49 C.F.R. § 195.446(c)(2). 12. Item 6- 49 C.F.R. § 195.446(h)(6): The Notice alleged that Magellan failed to include in its procedures team training and exercises that included both controllers and other individuals, defined by the operator, who would reasonably be expected to operationally collaborate with controllers (control room personnel) during normal, abnormal or emergency situations. Specifically, the Notice alleged that Magellan’s procedures did not require for the three operational modes (normal, abnormal, emergency) inclusion of any type of soft skills training; that team trainings and exercises did not include both controllers and those who would be expected to#

32023026NOPV_Consent Agreement and Order_05212024_(22-240208)_text.pdf, page 7collaborate with controllers; that Magellan’s emergency type response drills were inadequate to suffice as team training; and that Magellan’s procedures did not define who is responsible for developing and conducting team training and how to engage the "others" with controllers. Respondent does not contest the allegation of violation as alleged in the Notice. As such, PHMSA finds a violation of 49 C.F.R. § 195.446(h)(6). III. Warning Items: 13. Item 4- 49 C.F.R. § 195.446(e)(4): The Notice alleged that Magellan’s records for the annual review of the Alarm Management Plan to determine effectiveness was not adequate to demonstrate compliance. Specifically, the Notice alleged that Magellan’s documentation did not show what was considered and included in the review of the Alarm Management Plan to determine its effectiveness and that the records provided did not show the review’s findings or follow-up actions, if any, to improve the effectiveness of the plan. This Item was brought as a Warning Item and does not constitute a finding of violation. Respondent accepts the warning as alleged in the Notice. 14. Item 5- 49 C.F.R. § 195.446(h): The Notice alleged that Magellan’s training content review results and modifications failed to demonstrate an adequate review of the training program content to identify potential improvements at least once each calendar year, but at intervals not to exceed 15 months. Specifically, the Notice alleged that Magellan recommended National Center for Construction Education and Research (NCCER) booklets be eliminated as a training content and an Authorization for Expenditure (AFE) to expand the simulator capabilities however, Magellan had no records documenting how these decisions were reached. This Item was brought as a Warning Item and does not constitute a finding of violation. Respondent accepts the warning as alleged in the Notice. 15. Item 7- 49 C.F.R. § 195.446(j)(1): The Notice alleged that Magellan did not provide records adequate to demonstrate compliance for verification of correct safety related alarm set points and alarm descriptors when associated field instruments are calibrated or changed and at least once each calendar year, but at intervals not to exceed 15 months. Specifically, the Notice alleged the Magellan’s records from 2019, 2020, and 2021 did not show what alarms were reviewed, or which notations of identified deficiencies and corrections were completed, as required by the SCADA and Operations Control Supervisor in SIP 9.02-ADM-084, Revision 5, dated January 01, 2021, section 2.2 and 2.3. This Item was brought as a Warning Item and does not constitute a finding of violation. Respondent accepts the warning as alleged in the Notice. IV. Items 2 and 3: 16. Item 2- 49 C.F.R. § 195.446(c)(3): With respect to Item 2 of the Notice, the Parties agree that the nature of the alleged violation, asserting that Magellan’s internal communication plan for safe manual operation was not adequate to demonstrate compliance, is more appropriate for resolution by a Notice of Amendment (NOA). The Parties agreed during the informal discussion that Item 2 will be changed to an NOA item provided that Magellan (1) submits a model procedure of one segment/console for PHMSA’s review and (2) tests and verifies that model procedure on the relevant segment/console within one year of the Effective Date of this#

32023026NOPV_Consent Agreement and Order_05212024_(22-240208)_text.pdf, page 8Agreement. Because this Item will be changed to an NOA, it will not constitute a finding of violation for any purpose. 17. Item 3- 49 C.F.R. § 195.446(c)(5): With respect to Item 3 of the Notice, the Parties agree that the nature of the alleged violation, asserting that Magellan’s procedure failed to include Section 5 of API RP 1168 to establish a procedure for when a different controller assumes responsibility including the content of information to be exchanged, is more appropriate for resolution by an NOA. The Parties agreed during the informal discussion that Item 3 will be changed to an NOA item. Following the informal discussion between the Parties, Magellan provided a revised copy of the relevant procedures which are adequate to demonstrate compliance. As such, no further action is required. V. Civil Penalty: 18. Item 6: The Notice proposed assessing a civil penalty in the amount of $39,100. Respondent did not contest the proposed civil penalty for this Item. As such, Respondent shall pay a civil penalty in the amount of $39,100 for Item 6. 19. Respondent shall pay a civil penalty in the amount of $39,100, pursuant to the payment instructions at 49 C.F.R. § 190.227(a), to be paid in full no later than 20 days from the Effective Date of this Agreement. VI. Compliance Order: 20. Item 1: The Notice proposed certain compliance order actions to address the non- compliance alleged in the Notice. Respondent did not contest the Proposed Compliance Order. Following the informal discussion, and review of Magellan’s submitted revised procedures, Magellan completed the terms of the Proposed Compliance Order. As such, no further action is required. 21. Item 6: The Notice proposed certain compliance order actions to address the non- compliance alleged in the Notice. Respondent requested a modification to the timeline for compliance for this Proposed Compliance Order. The Region finds the extended timeline for compliance appropriate. As such, Respondent agrees to perform the following corrective measures: B. In regard to Item 6 of the Notice pertaining to Magellan failing to not include team training and exercises that included both controllers and other individuals, defined by the operator, who would reasonably be expected to operationally collaborate with controllers (control room personnel) during normal, abnormal or emergency situations, Magellan must modify it procedures to include team trainings and exercises that include both controllers and those who would be expected to collaborate with controllers, i.e., “others.” The procedure must include the topics to be covered during the training sessions. Magellan must also modify its procedures to include training for all modes of operation (normal, abnormal and emergency) as well as some soft skills. The operator must then complete the team#

32023026NOPV_Consent Agreement and Order_05212024_(22-240208)_text.pdf, page 9training for all “others” and controllers and provide documentation by December 31, 2024. 1 VII. Enforcement: 22.
