Crocker Springs Road Fellows, California 93224 CPF 5-2024-013-NOA Dear Mr. Jans: From March 6, 2023, through March 9, 2023, representatives of the Pipeline and Hazardous Materials Safety Administration (PHMSA), Office of Pipeline Safety (OPS), pursuant to Chapter 601 of 49 United States Code (U.S.C.), inspected Midway Sunset Cogeneration's (Midway) natural gas transmission line from the Kern River tie-in to the Midway Plant in Fellows, California. As a result of the inspection, PHMSA has identified the apparent inadequacies found within Midway’s plans or procedures. The item inspected and the inadequacy is described below: 1. § 192.465 External corrosion control: Monitoring and remediation. (a) . . . . (d) Each operator must promptly correct any deficiencies indicated by the inspection and testing required by paragraphs (a) through (c) of this section. For onshore gas transmission pipelines, each operator must develop a remedial action plan and apply for any necessary permits within 6 months of completing the inspection or testing that identified the deficiency. Remedial action must be completed promptly, but no later than the earliest of the following: prior to the next inspection or test interval required by this section; within 1 year, not to exceed 15#

52024013NOA_Notice of Amendment_07112024_(23-264914)_text.pdf, page 2months, of the inspection or test that identified the deficiency; or as soon as practicable, not to exceed 6 months, after obtaining any necessary permits. Midway’s procedures for corrosion control monitoring were inadequate to ensure the safe operation of a pipeline as required by § 192.465(d). Specifically, a review of Midway’s written Corrosion Control Inspection Procedure, located within the Operations and Maintenance Manual, showed that Midway lacked a stipulated timeline or timeframe for completing remediation after identification. Midway’s procedure for monitoring and remediating deficiencies does not state an explicit time period by which a corrective action plan will be developed and implemented in accordance with § 192.465(d). See, Section 105 of Midway’s Corrosion Control Inspection Procedure, Exhibit C. Midway’s procedure must designate a timeline for remedial action in accordance with the regulation. Accordingly, Midway must amend its procedures to fully conform to the requirements of § 192.465(d).
