ilPacific Gas and <br /> Electric Company <br /> Attachment 1 —Gas Facilities <br /> There could be gas transmission pipelines in this area which would be considered critical <br /> facilities for PG&E and a high priority subsurface installation under California law. Care must be <br /> taken to ensure safety and accessibility. So, please ensure that if PG&E approves work near <br /> gas transmission pipelines it is done in adherence with the below stipulations. Additionally,the <br /> following link provides additional information regarding legal requirements under California <br /> excavation laws: https://www.usanorth8ll.org/images/pdfs/CA-LAW-2018.pd <br /> 1. Standby Inspection:A PG&E Gas Transmission Standby Inspector must be present <br /> during any demolition or construction activity that comes within 10 feet of the gas pipeline.This <br /> includes all grading,trenching, substructure depth verifications(potholes),asphalt or concrete <br /> demolition/removal, removal of trees,signs, light poles, etc.This inspection can be coordinated <br /> through the Underground Service Alert(USA)service at 811.A minimum notice of 48 hours is <br /> required. Ensure the USA markings and notifications are maintained throughout the duration of <br /> your work. <br /> 2. Access:At any time, PG&E may need to access,excavate, and perform work on the gas <br /> pipeline.Any construction equipment, materials,or spoils may need to be removed upon notice. <br /> Any temporary construction fencing installed within PG&E's easement would also need to be <br /> capable of being removed at any time upon notice.Any plans to cut temporary slopes <br /> exceeding a 1:4 grade within 10 feet of a gas transmission pipeline need to be approved by <br /> PG&E Pipeline Services in writing PRIOR to performing the work. <br /> 3. Wheel Loads:To prevent damage to the buried gas pipeline,there are weight limits that <br /> must be enforced whenever any equipment gets within 10 feet of traversing the pipe. <br /> Ensure a list of the axle weights of all equipment being used is available for PG&E's Standby <br /> Inspector.To confirm the depth of cover,the pipeline may need to be potholed by hand in a few <br /> areas. <br /> Due to the complex variability of tracked equipment,vibratory compaction equipment, and <br /> cranes, PG&E must evaluate those items on a case-by-case basis prior to use over the gas <br /> pipeline(provide a list of any proposed equipment of this type noting model numbers and <br /> specific attachments). <br /> No equipment may be set up over the gas pipeline while operating. Ensure crane outriggers are <br /> at least 10 feet from the centerline of the gas pipeline.Transport trucks must not be parked over <br /> the gas pipeline while being loaded or unloaded. <br /> 4. Grading: PG&E requires a minimum of 36 inches of cover over gas pipelines(or existing <br /> grade if less)and a maximum of 7 feet of cover at all locations.The graded surface cannot <br /> exceed a cross slope of 1:4. <br /> 5. Excavating:Any digging within 2 feet of a gas pipeline must be dug by hand. Note that <br /> while the minimum clearance is only 24 inches, any excavation work within 24 inches of the <br /> edge of a pipeline must be done with hand tools.So to avoid having to dig a trench entirely with <br /> hand tools,the edge of the trench must be over 24 inches away.
