Narrative
At approximately 0320 hours on august 24, 2014, a magnitude 6.0 earthquake struck the napa county area causing damage to distribution facilities resulting in an unintentional release of gas from both pg&e and customer facilities. Over 11,000 distribution services were surveyed and over 675,000 feet of distribution main was surveyed. Pg&e has detected and repaired over 1,300 leaks on its gas distribution system throughout the counties of napa, solano and sonoma. External forces from the earthquake were responsible for an estimated service disruption to approximately 160 customers. The majority of these are due to leaks on customer facilities. In addition, pg&e responded to over 5,800 customer initiated requests related to gas odor calls, leak checks, pilot relights, gas turn-ons, and performed approximately 2,500 additional courtesy safety checks. There are no known injuries or deaths relating to pg&e's gas facilities. Pg&e reported this incident to the DOT and the cpuc based on operator judgment of the significance of this event. Please note that pg&e's responses to particular sections of this report may not apply as our reporting is on the repair and response work performed on pg&e's gas distribution system and not a specific location. (note: the earthquake magnitude has been corrected from 6.1 to 6.0 in this PHMSA 7100 supplemental report.)
