footprint of the landfill requires site personnel to review all as-built drawings to ensure no utilities are located in the work areas. 5.1.7 Sites Containing Fiber Optic Cables Because of the sensitivity of fiber optic cables and the cost costs of damaging them, the following process,effective immediately,will be adopted as mandatory and as a minimum effort. 1) When a CB&I PM or staff person becomes aware that a site requiring subsurface work contains a fiber optic cable within 50 feet of the outside working boundary, he/she will immediately notify the PM/BLM. The BLM—or if no BLM is in place the PM—will immediately notify the Area Manager and the HSR. The PM and the HSR will develop a work plan capable of accomplishing site activities while guaranteeing that fiber optic cables will not be affected. 2) Any subsurface activities conducted at a site as described in item 1, will require the on-site presence of the HSR or a designee as affirmed in writing by the HSM. 3) No subsurface work will occur at a site as referred to in item 1, without the owner of the fiber optic cable being present. 4) The fiber optic cable will not be considered located unless a representative of the owner of the fiber optic cable has visited the site, confirmed the location of the cable, and signed the work plan which shall contain a site plan indicating the locations(s) of the subsurface work and location of the fiber optic cable. 5) Deviation from any of the above points, items 1 through 4,must be approved by the Area Manager. 5.1.8 Overhead Utility Line Contact Observe CB&I Procedure CMS-710-02-PR-06600. Observe the following overhead utility line contact procedures and practices: • The CMS-710-02-PR-05300 Extra Hazardous and Repair Work ("Red Sheet") shall be completed each time overhead power lines are identified on site work area(s). • Maintain appropriate distance from overhead utilities: • Maintain at least 10 feet from overhead power lines, up to 50 kV • For voltages over 50 kV, add 0.4 inches per kV to obtain the safe distance between equipment and power lines. • If voltage is unknown,remain at least 20 feet from overhead power lines. • Conduct a daily site inspection to determine where activities will take place and the location of overhead utilities and overhead obstructions. Once identified place-warning tape on poles and/or guy wires and attempt to plan the work so that no contact will be made with the overhead utilities or obstructions. Share the in-formation with the all site personnel. As a precaution, a spotter will be used at all times during the construction phase when near overhead utilities or overhead obstructions. If contact is deemed un-avoidable, consult with the plant manager and HSM to evaluate the area to deter-mine if the particular overhead utility or obstruction can be removed prior to engaging in the activity. 5-3
