` u3 lid lee e f � flee le Attachment 1 Gas Pacilltles There could be gas transmission pipelines in this area which would be considered critical facilities for PG & E and a high priority subsurface installation under California law . Gare must be taken to ensure safety and accessibility . So , please ensure that if PG & E approves work near gas transmission pipelines it is done in adherence with the below stipulations . Additionally , the following link provides additional information regarding legal requirements under California excavation laws : http : // L1sanorth81 . sir lvi� content/ uploads / 2017 /05 /CA.- LAS/- English . pdf 1 . Standby Inspection : A PG & E Gas Transmission Standby Inspector must be present during any demolition or construction activity that comes within 10 feet of the gas pipeline . This includes all grading , trenching , substructure depth verifications ( potholes) , asphalt or concrete demolition /removal , removal of trees , signs , light poles , etc , This inspection can be coordinated through the Underground Service Alert ( USA) service at 811 . A minimum notice of 48 hours is required , Ensure the USA markings and notifications are maintained throughout the duration of your work. 2 . Access : At any time , PG & E may need to access , excavate , and perform work on the gas pipeline . Any construction equipment , materials , or spoils may need to be removed upon notice . Any temporary construction fencing installed within PG & E ' s easement would also need to be capable of being removed at any time upon notice . Any plans to cut temporary slopes exceeding a 1 : 4 grade within 10 feet of a gas transmission pipeline need to be approved by PG & E Pipeline Services in writing PRIOR to performing the work . 3 . Wheel Loads : To prevent damage to the buried gas pipeline , there are weight limits that must be enforced whenever any equipment gets within 10 feet of traversing the pipe . Ensure a list of the axle weights of all equipment being used is available for PG & E ' s Standby Inspector . To confirm the depth of cover , the pipeline may need to be potholed by hand in a few areas . Due to the complex variability of tracked equipment , vibratory compaction equipment , and cranes , PG & E must evaluate those items on a case-by- case basis prior to use over the gas pipeline ( provide a list of any proposed equipment of this type noting model numbers and specific attachments) . No equipment may be set up over the gas pipeline while operating , Ensure crane outriggers are at least 10 feet from the centerline of the gas pipeline . Transport trucks must not be parked over the gas pipeline while being loaded or unloaded . 4 . Grading : PG & E requires a minimum of 36 inches of cover over gas pipelines ( or existing grade if less) and a maximum of 7 feet of cover at all locations . The graded surface cannot exceed a cross slope of 1 : 4 . 5 . Excavating : Any digging within 2 feet of a gas pipeline must be dug by hand . Note that while the minimum clearance is only 12 inches , any excavation work within 24 inches of the edge of a pipeline must be done with hand tools . So to avoid having to dig a trench entirely with hand tools , the edge of the trench must be over 24 inches away . ( Doing the math for a 24 inch wide trench being dug along a 36 inch pipeline , the centerline of the trench would need to be at least 54 inches [24/2 + 24 + 36/2 = 54 ] away , or be entirely dug by hand . ) PG &E Gas and Electric Facilities page 2
