Box 1902888\nAnchorage, AK 99519-0288\nCPF 5-2011-0021W\nDear Mr. Bredin:\nOn September 26-28, 2011, a representative of the Pipeline and Hazardous Materials Safety\nAdministration (PHMSA), pursuant to Chapter 601 of 49 United States Code, inspected your\nWhittier/Girdwood Pipeline in Anchorage, Alaska.\nAs a result of the inspection, it appears that you have committed probable violations of the\nPipeline Safety Regulations, Title 49, Code of Federal Regulations. The items inspected and\nthe probable violations are:\n1. §192.481 Atmospheric corrosion control: Monitoring.\n(a) Each operator must inspect each pipeline or portion of pipeline that is\nexposed to the atmosphere for evidence of atmospheric corrosion, as follows:\nIf the pipeline is lo-\ncated:\nThen the frequency of inspection is:\nOnshore …………. At least once every 3 calendar years,\nbut with intervals not exceeding 39\nmonths\nOffshore …………. At least once each calendar year, but\nwith intervals not exceeding 15\nmonths\n(b) During inspections the operator must give particular attention to pipe at\nsoil-to-air interfaces, under thermal insulation, under disbonded coatings, at\n\n\n\npipe supports, in splash zones, at deck penetrations, and in spans over water.\n1) Enstar’s pipeline runs approximately 3 miles through a tunnel just before\nWhittier. The pipe in the tunnel is subject to atmospheric corrosion\nmonitoring.\n2) Entsar’s annually ground patrol indicated several locations where the pipeline\nIs exposed and is subject to atmospheric corrosion.\n2. §192.723 Distribution systems: Leakage surveys.\n(a) Each operator of a distribution system shall conduct periodic leakage\nsurveys in accordance with this section.\n(b) The type and scope of the leakage control program must be determined by\nthe nature of the operations and the local conditions, but it must meet the\nfollowing minimum requirements:\n(1) A leakage survey with leak detector equipment must be conducted in\nbusiness districts, including tests of the atmosphere in gas, electric, telephone,\nsewer, and water system manholes, at cracks in pavement and sidewalks, and at\nother locations providing an opportunity for finding gas leaks, at intervals not\nexceeding 15 months, but at least once each calendar year.\n(2) A leakage survey with leak detector equipment must be conducted outside\nbusiness districts as frequently as necessary, but at least once every 5 calendar\nyears at intervals not exceeding 63 months. However, for cathodically\nunprotected distribution lines subject to § 192.465(e)\non which electrical surveys for corrosion are impractical, a leakage survey must\nbe conducted at least once every 3 calendar years at intervals not exceeding 39\nmonths.\nThe right-of-way between Power Line Pass and Twenty Mile has become overgrown\nwith vegetation and prevents effective patrolling and leak detection.\nUnder 49 United States Code, § 60122, you are subject to a civil penalty not to exceed\n$100,000 for each violation for each day the violation persists up to a maximum of\n$1,000,000 for any related series of violations. We have reviewed the circumstances and\nsupporting documents involved in this case, and have decided not to conduct additional\nenforcement action or penalty assessment proceedings at this time. We advise you to correct\nthe items identified in this letter. Failure to do so will result in Enstar Natural Gas Company\nbeing subject to additional enforcement action.\nNo reply to this letter is required. If you choose to reply, in your correspondence please refer\nto CPF 5-2011-0021W. Be advised that all material you submit in response to this\nenforcement action is subject to being made publicly available. If you believe that any\n2\n\n\n\nportion of your responsive material qualifies for confidential treatment under 5 U.S.C.\n552(b), along with the complete original document you must provide a second copy of the\ndocument with the portions you believe qualify for confidential treatment redacted and an\nexplanation of why you believe the redacted information qualifies for confidential treatment\nunder 5 U.S.C. 552(b).\nSincerely,\nDennis Hinnah\nDeputy Director, Western Region\nPipeline and Hazardous Materials Safety Administration\nCc: PHP-60 Compliance Registry\nPHP-500 B.
