Pacific Gas and <br /> S E/actiic Company <br /> Attachment 1 —Gas Fac1lltlas <br /> There could ba gas transmission pipelines in this area which would b¢considered critical <br /> facilities for PGBE and a high priority subsurtace installation under California law. Cara must ba <br /> taken to ensure safety and accessibility. So, pl¢ase ensure that if PGBE approves work near <br /> gas transmission pipelines it is done in adherence with the below stipulations. Additionally, the <br /> following link provid¢s additional information regarding legal requirements under California <br /> excavation Taws: htt s://www.us no h8 t'I.or /ima es/ dfs/CA W 20th. df <br /> t. Standby Inspection: A PGBE 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 th¢duration of ' <br /> your work. <br /> 2. Access: At any time, PGBE may Head to access, excavate, and perform work on the gas <br /> pipeline. Any construction aquipm¢nt, materials, or spoils may need to b¢removal upon notice. <br /> Any temporary construction fencing installed within PGBE's easement would also Head to ba <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 /> PGBE Pipeline Services in writing PRIOR to performing the work. <br /> 3. Wheel Loads: To prevent damage to the buried gas pipelin¢, that¢are weight limits that <br /> must be¢nforc¢d when¢ver any equipment gets within 1 O feet of traversing the pipe. <br /> Ensure a list of the axle weights of all equipment being used is available for PGBE'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, PGBE must evaluate those items on a case-by-ease basis prior to use over[he 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 1 O feat 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: PGBE requires a minimum of 36 inches of cover over gas pipelines (or existing <br /> grade if less) and a maximum of 7 feat of cover at all locations. The grad¢d surtace cannot <br /> ¢xc¢ed a cross slope of t: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 t2 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.
