PACIFIC GAS & ELECTRIC CO — Integrity Assurance Notification

MAOP RECONFIRMATION METHOD 6Pacific Gas and Electric Company (PG&E) has performed a comprehensive evaluation of all station features at the New Westley Town Station (“New Westley”) to reconfirm the Maximum Allowable Operating Pressure (MAOP).1 This station is in Stanislaus County, California and supplies gas to District Regulator Station HP-21. The initial scope of this effort identified all traceable, verifiable, and complete (TVC) records to reconfirm MAOP based on design and pressure test records. Four pipe joints at New Westley were identified as not having TVC records of a valid pressure test2 in this initial review. PG&E proposes to establish a TVC MAOP record via 49 Code of Federal Regulations (CFR) §192.624(c)(3), Method 3.3 This submittal is based on previous submittals to the Pipeline and Hazardous Materials Safety Administration (PHMSA) and the California Public Utilities Commission (CPUC) for the MAOP reconfirmation via Engineering Critical Assessment (ECA). PG&E applied this methodology to the features at the Bradbury Rd Regulator Station4 and Elk River Road Regulator Station5. The Bradbury submittal received a no-objection response from PHMSA. Elk River was submitted for review on February 9, 2022 and did not received an objection or request for additional time for review after 91 days. Previous correspondence from PHMSA indicated that all subsequent applications of this methodology would require submittal to PHMSA and CPUC for review.#
