On the basis of the inspection, PHMSA has identified the apparent inadequacies found within Marathon's plans or procedures, as described below: 1. 192.605 Procedural manual for operations maintenance and emergencies. (b)(3) Making construction records, maps, and operating history available to appropriate operating personnel. Appendix 8, page I and page 4 of Marathon's Standard Operating & Maintenance Procedures Manual, did not reflect the new 1120 psi. "set pressure" ofreliefvalve X028 at Granite Point. 2. 192.465 External corrosion control: Monitoring. (d) Each operator shall take prompt remedial action to correct any deficiencies indicated by the monitoring. 3. 4. t. 6. Marathon's Standard Operating & Maintenance Procedures Manual, did not indicate that prompt remedial action must be taken when deficiencies are found during corrosion control monitoring. 192.485 Remedial measures: Transmission lines. (c) Under paragraphs (a) and (b) ofthis section, the strength of pipe based on actual remaining wall thickness may be determined by the procedure in ASME/ANSI B31G or the procedure in AGA Pipeline Research Committee Project PR 3-805 (with RSTRENG disk). Both procedures apply to corroded regions that do not penetrat€ the pipe wall, subject to the limitations prescribed in the procedures. Marathon's Standard Operating & Maintenance Procedures Manual did not have procedures for utilizing 831G or Rstreng to determine the remaining strength ofa pipeline. 192.613 Continuing surveillance, (b) If a segment of pipeline is determined to be in unsatisfactory condition but no immediate hazard exists, the operator shall initiate a program to recondition or phase out the segment involved, or, if the segment cannot be reconditioned or phased out, reduce the maximum allowable operating pressure in accordance with $192.619 (a) and (b). Marathon's Standard Operating & Maintenance Procedures Manual, did not indicate what action must be taken if a line segment is found in unsatisfactory condition. 192.615 Emergency plans. (a) Each operator shall establish written procedures to minimize the hazard resultins from a gas pipeline emergency. At a minimum, the procedures must provide for the following: (1) Receiving, identiSing, and classifuing notices of events which require immediate response by the operator, (2) Establishing and maintaining adequate means of communication with appropriate fire, police, and other public officials. (3) Prompt and effective response to a notice of each type of emergency, including the following: (i) Gas detected inside or near a building. Marathon's Standard Operating & Maintenance Procedures Manual, did not indicate what action must be taken ifgas is detected inside or near a building. 192.627 Tapping pipeline under pressure. Each tap made on a pipeline under pressure must be performed by a crew qualified to make hot taps. Marathon's Standard Operating & Maintenance Procedures Manual did not rcquire that the crew that performs hot tapping must be qualified. 7, 192.709(c) Transrnission lines: Record keeping. (c) A record of each patrol, survey, inspection, and test required by subparts L and M of this part must be retained for at least 5 years or until the next patrolt survey' inspection, or test is completed, whichever is longer. Marathon's Standard Operating & Maintenance Procedures Manual, did not indicate that valve inspection records must be maintained for 5 years. 8. l92.7LS Transmission line: Permanent field repair of welds, (b) A weld may be repaired in accordance with $192.245 while the segment of transmission line is in service if: (1) The weld is not leaking: (2) The pressure in the segment is reduced so that it does not produce a stress that is more than 20 percent of the SMYS of the pipe; and (3) Grinding of the defective area can be limited so that at least l/8-inch (3.2 millimeters) thickness in the pipe weld remains. Marathon's Standard Operating & Maintenance Procedures Manual, did not state under what condition a field repair of a weld could be performed. 9. 192.7 45(b\ Valve maintenance: Transmissioin lines. (b) Each operator must take prompt remedial action to correct any valve found inoperable, unless the operator designates an alternative valve. Marathon's Standard Operating & Maintenance Procedures Manual, did not indicate that prompt remedial action must be taken when an inoperable valve is found. 10. 192.7 49 Vault maintenance. (a) Each vault housing pressure regulating and pressure limiting equipment, and having a volumetric internal content of200 cubic feet (5.66 cubic meters) or more, must be inspected at inter"vals not exceeding 15 months, but at least once each calendar year, to determine that it is in good physical condition and adequately ventilated. (b) If gas is found in the vault, the equipment in the vault must be inspected for leaks, and any leaks found must be repaired. (c) The ventilating equipment must also be inspected to determine that it is functioning properly. (d) Each vault cover must be inspected to assure that it does not present a hazard to public safety. Marathon's Standard Operating & Maintenance Procedures Manual did not indicate that vault inspections must be conducted annually.
