Based on our inspection findings, PHMSA determined that Alyeska committed a probable violation of the Pipeline Safety Regulations, Title 49, Code of Federal Regulations (CFR). The deficiency noted and the probable violation is: 1) §195.583 What must I do to monitor atmospheric corrosion control? (a) You must inspect each pipeline or portion of pipeline that is exposed to the atmosphere for evidence of atmospheric corrosion, as follows: If the pipeline is located: Then the frequency of inspection is: Onshore At least once every 3 calendar years, but with intervals not exceeding 39 months. Offshore At least once each calendar year, but with intervals not exceeding 15 months. At the time of the inspection, Alyeska personnel stated that an atmospheric corrosion inspection on Check Valve 00-CKV-8 was not conducted on the required three year inspection interval for onshore facilities per CFR §195.583(a). Alyeska staff provided a record of an atmospheric corrosion inspection that was conducted on July 21, 2014 on Check Valve 00-CKV-8 during the inspection. Alyeska personnel scheduled and conducted an atmospheric inspection of Check Valve 00-CKV-8 on March 13, 2018 and provided records of the inspection to PHMSA on April 9, 2018. The interval between atmospheric corrosion inspections on Check Valve 00-CKV-8 is approximately three and a half years. Under 49 U.S.C. § 60122 and 49 CFR § 190.223, you are subject to a civil penalty not to exceed $209,002 per violation per day the violation persists, up to a maximum of $2,090,022 for a related series of violations. For violations occurring prior to November 2, 2015, the maximum penalty may not exceed $200,000 per violation per day, with a maximum penalty not to exceed $2,000,000 for a related series of violations.
