In the wake of the September gas pipeline explosion that killed eight people and leveled part of a neighborhood in San Bruno, California, Pacific Gas & Electric Co. says it has found 38 leaks in California that require immediate attention.
And its pipeline survey is just getting started.
The company is using aerial laser detection technology as well as traditional ground patrols to search for leaks, starting in heavily populated areas. It expects to complete the survey in December.
Four of the 38 leaks have been repaired, the company said.
PG&E says it also is evaluating 300 locations where it might be able to swap out manual valves for automated or remotely controlled ones, making it possible to shut off gas more quickly and avoid disaster in case of a pipeline rupture.
