摘要

California Public Utilities Commission (GPUC) ordered intrastate gas transmission operators to file an Implementation Plan, to pressure test or replace all in-service natural gas transmission pipelines that have never been pressure tested. 1 Requirement that all in-service natural gas transmission pipeline will be pressure tested in accordance with 49 CFR 192.619, excluding 49 CFR 192.619(c). 2 Prioritize pipeline segments located in Class 3 and Class 4 locations and Class 1 and Class 2HCA's 3 Contain priority-ranked schedule for pressure testing based on risk assessment 4 Set forth criteria on which pipeline segments were identified for replacement instead of pressure testing. 5 Must consider retrofitting pipeline to allow for in-line inspection tools and where appropriate, automated or remote controlled shut off valves. 6 Include interim safety enhancement measures, such as increased patrols and leak surveys, pressure reductions, and prioritization of pressure testing of critical pipelines.
