PACIFIC GAS & ELECTRIC CO — Integrity Assurance Notification

REASSESSMENT INTERVAL BELOW 30% SMYSPacific Gas and Electric Company (PG&E) is respectfully requesting to extend the reassessment interval of PG&E Gas Transmission Line 118G for an additional six (6) months pursuant to General Order 112-F §101.3 and 49 CFR Sections 192.939.Under §192.939(b), PG&E is required to conduct a reassessment of a covered segment of Line 118G by December 31st, 2021; however, under §192.939(b), PG&E may seek an extension of the reassessment interval if the operator demonstrates sufficient justification of the need for the extension.If required to meet the current December 31, 2021 reassessment due date, PG&E has concerns with maintaining product supply to 37,000 residential and commercial customers (including a powerplant and college campus) throughout Merced County. PG&E began running mechanical cleaning tools this year and encountered fine debris that was not expected. To avoid a potential stuck pig situation or pushing debris into regulation, PG&E has determined that liquid cleaning would be the best course of action to reduce risk prior to continuing the In-Line Inspection (ILI).For this reason, PG&E seeks a six (6) month extension of the reassessment due date of December 31, 2021. The request for extension is only applicable to Line 118G MP 2.27 to 2.55 and MP 4.37 to 6.23 for the threat of external corrosion. PG&E is committed to completing the integrity assessment on Line 118G as soon as possible, but no later than June 30th, 2022.Anticipated impact, risk, and mitigation were all considered in our decision to request this reassessment extension and are detailed as follows.#
