The item inspected and the probable\nviolation is:\n1. § 192.619 Maximum allowable operating pressure: Steel or plastic pipelines.\n(a) No person may operate a segment of steel or plastic pipeline at a pressure that exceeds a\nmaximum allowable operating pressure determined under paragraph (c) or (d) of this\nsection…\nAs indicated in your Safety Related Condition Report, Tennessee Gas Pipeline experienced an\noverpressure condition that met the reporting criteria for a safety related condition. On July 30,\n2012, a portion of your Cleveland District Unit’s pipeline was operated at a pressure that\n\n\n\nexceeded the maximum allowable operating pressure for the line. The established MAOP for the\nline, at the time of the event and report was 678 PSIG. The MAOP was exceeded for\napproximately 35 minutes with maximum pressures climbing into the 748 PSIG range. The\nmaximum pressures exceeded 110% the MAOP of the line at the time of the event.\nThis event is reflected in the Safety Related Condition Report you filed with PHMSA, as well as\nprovided SCADA documentation related to the event.\nWe have reviewed the circumstances and supporting documents involved in this case, and have\ndecided not to conduct additional enforcement action or penalty assessment proceedings at this\ntime.\nNo reply to this letter is required.
