PACIFIC GAS & ELECTRIC CO — Integrity Assurance Notification

MAOP RECONFIRMATION METHOD 6Pacific Gas and Electric Company (PG&E) has performed an engineering critical assessment (ECA) of joints at its Algonquin Power Meter Station (Algonquin Pwr Station) to reconfirm Maximum Allowable Operating Pressure (MAOP). This station is in Sanger, California and provides metered gas to serve the Algonquin Power Sanger LLC. PG&E’s initial phase of this project identified all traceable, verifiable, and complete (TVC) records to validate MAOP based on design and pressure test records. Twelve (12) joints, comprising of pipe and fittings, at the Algonquin Pwr Station, were identified as having non-TVC records of a pressure test. The joints considered in this evaluation are located in a Moderate Consequence Area (MCA) and are located in a Class 3 location. PG&E proposes to establish TVC MAOP records via 49 Code of Federal Regulations (CFR) §192.624(c)(3), Method 3: Engineering Critical Assessment (ECA).#
