CPUC is investigating last Friday’s (April 17, 2015) PG&E pipeline explosion in
Fresno. Upon learing of the explosion on Friday the CPUC immediately sent a team to Fresno to determine the cause of the explosion and whether
there were any violations of State or Federal law by PG&E.
While the in-depth analysis that is being performed by the CPUC’s Safety and
Enforcement Division will take some time to complete, the CPUC will work as
expeditiously as possible, with assistance from the federal Pipeline and
Hazardous Materials Safety Administration.
During the course of the investigation the CPUC will determine the physical
cause of the pipeline rupture and explosion, validate if there was an active
811 call-before-you-dig ticket, verify the accuracy of utility maps and other
records, assess PG&E’s emergency response performance, and evaluate any
factors contributing to the incident. Safety and Enforcement Division staff
will also monitor PG&E’s repair activities on the damaged pipeline to
ensure that it is fully repaired before it is brought back into service.
From initial information, it appears that there was a Fresno
County employee performing work in the vicinity of a pipeline and that
there was no active 811 call-before-you-dig ticket. The CPUC’s investigation
will determine whether this was the primary cause of the explosion.
The CPUC reminds everyone - whether you are a contractor replacing grass with
drought-resistant plants, or are planting a tree in your backyard - to call 811
before you dig to have your underground facilities marked. Read more about 811:
