PG&E Working In Brisbane

Printer-friendly versionPrinter-friendly version

The City was notified yesterday that PG&E detected two anomalies (pipe dents and metal loss) in their 30” diameter gas transmission line in San Bruno Mountain State and County Park within their easement.  They considered this repair an emergency, and thus proceeded with starting the repair work immediately.  Prior to doing so, they obtained an Encroachment Permit from the County of San Mateo Parks Department, had a Biological Assessment, including Revegetation Recommendations (prepared by Garcia and Associates Natural and Cultural Resources Associates), and prepared and received approval of their San Bruno Mountain Habitat Conservation Plan Site Activity Review Application for the work. 

Their work is on a north slope of the park, adjacent to and east of the PG&E electrical transmission towers and west of the quarry.  They are clearing an area within their easement and will walk an excavator up the cleared area to the two excavation locations, the higher being approximately 850’ up the hillside, in order to dig and repair the line.  They expect the work to take seven to 10 days, not including restoration activities.

While we would have preferred more notice to have been able to provide this information to residents and interested parties in advance, we recognize, as the San Mateo County Parks Department also did, that this was an urgent matter and the repair work needed to start immediately.  If you have any questions about this work, please contact the Public Works Department at 508-2130.
