Pacific Gas and E/ectric Company Attachment 1 —Gas Facilities Th¢ra could be gas transmission pipelines In this area which would be considered critical faciliti¢s for PGS.E and a high priority subsurtaca Installation under California law. Care must ba taken to ensure safety and accessibility. So, pl¢ase ensure that if PG8,E approves work near gas transmission pipelines It is done in adherence with the below stipulations. Additionally, the following link protides additional information regarding legal requirements under California excavation laws: htt d/ rthSt � /w - t t/ I d /2017!05/CA-LAW-Engl'sh odf �. Standby Inspection: A PG&E Gas Transmission Standby Inspector must be present during any demolition or construction activity that com¢s within 1 O feat of the gas pipeline. This includes all grading, trenching, substructure depth verifications (potholes), asphalt or concrete demolition/removal, removal of trees, signor, Ilght poles, etc. This inspection can ba coordinated through the Underground Service Alert (USA) service at 811. A minimum notice of 48 hours is r¢quired. 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 partortn work on the gas pipeline. Any construction equipment, materials, or spoils may need to be removed upon notice. Any temporary construction fencing installetl within PGBE'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 � O feet of a gas transmission pipeline need to ba approved by PG8,E Pip¢lina Services in writing PRIOR to pertorming the work. 3. Wheel Loads: To prevent damage to the buried gas pipeline, there are weight limits that must be enforced whenever any equipment gats within t O feet of traversing the pipe. Ensures a list of the axle weights of all equipment being used is available for PGBE's Standby Inspector. To confirm the depth of cover, Yha pipeline may need to be potholed by hand in a few areas. Dues to the complex variability of trackatl equipment, vibratory compaction equipment, and cranes, PG&E musk 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 aquipmani may be sat up over the gas pipeline while operating. Ensure crane outriggers are at least t O feat from the c¢nteriina of the gas pipeline. Transport trucks must not be parked over the gas pipeline while being loaded or unloaded. 4. Grading: PGBE requires a minimum of 36 Inches of cover over gas pipaltnas (or existing grade If less) and a maximum of 7 feat of cover at all locations. The graded surface cannot exceed a cross slope of 1:4. 5. Excavating: Any tllgging within 2 feat of a gas pipeline must ba 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 hantl 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 fora 24 Inch wide trench boring dug along a 36 Inch pipeline, the centerline of the trench would need to be at laasi 54 inches [24/2 + 24 + 36/2 = 64] away, or ba entirely dug by hand.)
