Pacific Gas and Electric Company„ Attachment 1 — Gas Facilities - 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. Care 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://usarrorLh8l l,org/wp-contp-nt/uploads/2017/05/CA-LAW-English.pdf 1. Standby Inspection: A PG&E Gas Transmission Standby Inspector mu-st be present during any demolition or construction activity -that -comes within 10 feet of the gas pipeline. This inciudes 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 Under -ground 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 tieing removed at anytime 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 1-0 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 num.:bers and specific attachments). No equipment may be set up over the gas pipeline -while operating_ Ensure craneoutriggers 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.)
