Pacific Gas and <br /> S E/ectric Company" <br /> Attachment 1 —Gas Facilities <br /> There could ba gas transmission pipelines in this area which would ba considered critical <br /> facilities for PG8.E and a high priority subsurtace installation under California law. Cara must be <br /> taken to ensure safety and accessibility. So, please ensure that if PGS,E approves work near <br /> gas transmission pipelines it is done in adherence with the below stipulations. Additionally, the <br /> following Zink provides additional information regarding legal requirements under California <br /> excavation laws: htt -// rth811 /" / df /CA-LAW-2018 df <br /> 1. Standby Inspection: A PG&E Gas Transmission Standby Inspector must ba present <br /> during any demolition or construction activity that comes within 1 O 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 ba coordinated <br /> through the Underground Service Alert(USA) service at 81 t. 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, PG8.E may need to access, excavate, and partorm work on the gas <br /> pipeline. Any construction equipment, materials, or spalls may Head 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 feat of a gas transmission pipalina need to be approved by <br /> PG&E Pipeline Services in writing PRIOR to partorming 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 1 O feat of traversing the pipe. <br /> Ensure a list of the axle weights of all equipment being used is available for PGS.E's Standby <br /> Inspector. To confirm the depth of cover, the pipalina may need to ba potholed by hand in a few <br /> areas. <br /> Oua to the complex variability of tracked equipment, vibratory compaction equipment, and <br /> cranes, PGBE 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 modal 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 feet from the centerline of the gas pipeline. Transport trucks must not ba 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 lass) and a maximum of 7 feet of cover at all locations. Tha graded surface cannot <br /> exceed a cross slope of 1:4. <br /> 5. Excavating: Any digging within 2 feat of a gas pipeline must be dug by nand. Note that <br /> while the minimum clearance is only 24 inches, any excavation work within 24 inches of tna <br /> edge of a pipeline must be lona with hand tools. So to avoid having to dig a Trench entirely with <br /> hand tools, the edge of the trench must ba over 24 inches away.
