Pacific Gas & Electric Co. released a list of the top 100 "high risk" pipelines to the state Public Utilities Commission earlier today and posted the information online. The San Bruno pipeline that exploded Sept. 9 was not on the list.
Though previous documents that PG&E filed with the state Public Utilities Commission indicated that a stretch of pipeline, known as Line 132, in South San Francisco was designated as one of its top 100 high-risk segments and was slated for replacement, that segment was not on the list released today. Rather, the list included a segment of Line 132 between Milpitas and Crystal Springs Reservoir.
Attached is the PG&E report that lists the top 100 pipelines in question and a map of pipelines that run through San Francisco and San Mateo counties.
Lines that PG&E is evaluating on the Peninsula include:
- An engineering review of 18 feet of pipe near Dunbarton Street and Donahoe Street in Menlo Park.
- The design materials of 105 feet of pipe near Brittan Avenue and El Camino Real in San Carlos.
- An assessment for the potential for ground movement along 10 feet of pipe near Milpitas-Alviso Road and Ranch Drive in San Jose.
- An engineering review of 10 feet of pipe near Milpitas-Alviso Road and Ranch Drive in San Jose.
In addition to the updated map and list of questionable pipelines, customers are encouraged to call the PG&E pipeline helpline at 1-888-743-7431 to determine whether they live within 500 feet of gas transmission pipelines.
