The items inspected and\nthe probable violation(s) are:\n1. S192.455 External corrosion control: Buried or submerged pipelines installed\nafter July 31,1971.\n(a) Except as provided in paragraphs (b), (c), and (f) of this section, each buried\nor submerged pipeline installed after July 31, 1971, must be protected against\nexternal corrosion, including the following:\n(1) It must have an external protective coating meeting the requirements of\ns192.461.\n(2) It must have a cathodic protection system designed to protect the pipeline in\naccordance with this subpart, installed and placed in operation within 1 year after\ncompletion of construction,\n(b) An operator need not comply with paragraph (a) of this section, if the operator\ncan demonstrate by tests, investigation, or experience in the area of applicationt\nincluding, as a minimum, soil resistivity measurements and tests for corrosion\naccelerating bacteria, that a corrosive environment does not exist. However,\n\n\n\nwithin 6 months after an installation made pursuant to the preceding sentence, the\noperator shall conduct tests, including pipe-to-soil potential measurements with\nrespect to either a continuous reference electrode or an electrode using close\nspacing, not to exceed 20 feet (6 meters)' and soil resistivity measurements at\npotential profile peak locations, to adequately evaluate the potential profile along\nthe entire pipeline. Ifthe tests made indicate that a corrosive condition exists, the\npipeline must be cathodically protected in accordance with paragraph (a)(2) of\nthis section,\nExamination of Norgasco's 6-inch diameter line segment between the Conoco-Phillips\nfacility and your Pressure Reduction Station #1 revealed corrosion at the soil-air\ninterface where the pipeline went under the road. The pipe surface was visibly\ncorroded and needs to be evaluated and re-coated where necessary to meet the\nrequirements of $ 192.461.\nUnder 49 United States Code, $ 60122, you are subject to a civil penalty not to exceed\n$100,000 for each violation for each day the violation persists up to a maximum of$l '000'000\nfor any related series ofviolations. We have reviewed the circumstances and supporting\ndocuments involved in this case, and have decided not to conduct additional enforcement\naction or penalty assessment proceedings at this time. We advise you to correct the item(s)\nidentified in this letter. Failure to do so will result in Norgasco being subject to additional\nenforcement action.\nNo reply to this letter is required. If you choose to reply, in your correspondence please refer\nto CPF 5-2007-0011W.
