Panhandle Eastern Pipeline Company (OPID 15105) submits this written notification to PHMSA as directed by § 192.714(e) for a pressure reduction that will exceed 365 days. The current temporary pressure reduction exceeded 365 days on September 27, 2024. On July 26, 2023, Panhandle Eastern Pipeline Company (PEPL) completed a geometry and metal loss in-line inspection (ILI) of the 12” Centralia 200 - 1800 River Line #2 pipeline. Discovery of an 89% deep external metal loss feature was made on September 27, 2023, after delivery of the ILI findings. Metal loss anomalies greater than 80% in depth of nominal wall thickness located outside of High Consequence Areas are immediate conditions per 49 CFR 192.714 (d)(1) and the Company In-Line Inspection Response Protocol. On September 27, 2023, the pipeline pressure was reduced to a level not exceeding 80% of the operating pressure per Company In-line Inspection Response Protocol. The pipeline was isolated, and pressure reduced from 584 psi to 420 psi.
