Main Street Findlay, OH 45840 CPF 5-2010-0002M Dear Mr. Swearingen: On August 17 and 21, 2009, representatives of the Pipeline and Hazardous Materials Safety Administration (PHMSA), pursuant to Chapter 601 of 49 United States Code, inspected Marathon Pipe Line LLC’s (Marathon) Operation and Maintenance procedures in Kenai, Alaska. On the basis of the inspection, PHMSA has identified the apparent inadequacies found within Marathon’s plans or procedures, as described below: 1. §192.475 Internal corrosion control: General. (a) Corrosive gas may not be transported by pipeline, unless the corrosive effect of the gas on the pipeline has been investigated and steps have been taken to minimize internal corrosion. Marathon’s procedures for internal corrosion are inadequate because they do not specify the methods used by Marathon for determining the corrosive properties of the transported gas. During the inspection Marathon indicated that it investigates the corrosive properties of the transported gas and provided the following internal corrosion control procedures: 1) Standard Number MPLMNT072, Internal Corrosion Management, Revision 1, dated 2/23/09; and 2) Standard Number MPLMNT020, Corrosion Management – Regulatory Compliance, Revision 10, dated 6/04/09. However, these procedures do not specify the methods used by Marathon for determining the corrosive properties of the transported gas. 2. §192.715 Transmission lines: Permanent field repair of welds. Each weld that is unacceptable under §192.241(c) must be repaired as follows: (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 Marathon’s procedures for repair of in-service weld defects are inadequate because they do not include the prescribed requirements §192.715(b)(1) and (2). Marathon provided Standard Number MPLMNT030, In-Service Welding, Revision Number 2, dated 12/15/06 as their in- service welding procedures. These procedures allow repair of in-service weld defects; however, they do not include the prescribed requirements of §192.715(b)(1) and (2). 3. §192.743 Pressure limiting and regulating stations: Capacity of relief devices (a) Pressure relief devices at pressure limiting stations and pressure regulating stations must have sufficient capacity to protect the facilities to which they are connected. Except as provided in §192.739(b), the capacity must be consistent with the pressure limits of §192.201(a). This capacity must be determined at intervals not exceeding 15 months, but at least once each calendar year, by testing the devices in place or by review and calculations. Marathon failed to provide procedures which require the capacity of the relief devices be determined at intervals not exceeding 15 months, but at least once each calendar year.
