PACIFIC GAS & ELECTRIC CO — Integrity Assurance Notification

REASSESSMENT INTERVAL ABOVE 30% SMYSPacific Gas and Electric Company (PG&E) is respectfully requesting an extension of the reassessment interval for PG&E’s Line 109 for an additional six (6) months pursuant to General Order 112-F §101.3 and 49 CFR Sections 192.939(a). Under §192.939(a), PG&E is required to conduct a reassessment of covered segments of Line 109 in a High Consequence Area (HCA) by December 31st, 2021; however, under §192.939(a), PG&E may seek an extension of the reassessment interval if it demonstrates sufficient justification of the need for the extension. PG&E had planned on performing a strength test project, however was unable to obtain a necessary permit in time to take an outage on the system and complete the reassessment work by the end of 2021. PG&E is expecting to receive the permit in approximately November 2021, but will not have time to take the line out of service before the end of the year without jeopardizing supply to customers. Additionally, the PB 175 outage will impact several compliance driven projects in the area that cannot be executed at the same time. PG&E plans to execute the Line 109 reassessment work next year when there would also be a bundling opportunity with planned work carrying the same system impacts. For these reasons, PG&E seeks a six (6) month extension of the current reassessment due date of December 31, 2021. The request for extension is only applicable to Line 109, MP 32.3827-32.6557, 36.4345-36.8642, 27.9689-28.3111 for the external corrosion threat. PG&E is committed to completing the integrity assessment on Line 109 as soon as possible, but no later than June 30th, 2022. Anticipated impact, risk, and mitigation were all considered#
