Narrative
On march 15, 2013, at approximately 0256 hours, pacific gas and electric (pg&e) was notified that a third party excavator, atazz technical services, was boring under east shaw avenue in fresno and struck a 6-inch steel gas distribution feeder main (dfm) 1202-09, resulting in a release of gas. Pg&es gas service representative (gsr) arrived on site at 0310 hours and gas service was shut off to two nearby commercial customers.
