Amendment to Statement of Work Section 4.4

4.4 Convert Tie Line to Feeder 43

The tie line runs east-west for approximately 4,200 ft on poles that carry a 110 kV ML&P power line.

Then it turns north-south for approximately 2,700 ft. A portion of the north-south power line right of way is in the airfield Clear Zone. See attached drawing for approximate location. An aerial power line cannot be installed in the airfield Clear Zone. The north-south portion of Feeder 43 can be installed below ground in the existing power line right of way or above ground outside of the airfield Clear Zone.

Approximately 100 ft of the power line crosses two of the Golf Course Greens and must be installed underground. New solid wood poles and cross arms are required for aerial portions of the north-south section of Feeder 43. The east-west section of the Feeder 43 will require new cross-arms on ML&P’s existing poles. Coordinate work on ML&P poles with ML&P. A future 34.5 kV line will be installed above Feeder 43. Size and configure solid wood poles and cross-arms accordingly. The new Feeder 43 shall be designed and installed to carry 300 Amps.

To connect Feeder 43 to Feeder 51, replace JC-43-1 with new SC-43-1 that shall be an S&C PME-11 or approved equal. A PME-11 is a 600 Amp 4-way dead front switch with 3 blade compartments and one fused compartment. Use dead break, 600 Amp elbows, for the new line. New elbows will have Test Point and fault indicator. Use the existing elbows, if possible, for the existing lines. Minimum cable size shall be for a 300 Amp load. Pole line shall be routed as shown on drawings, to Boniface Gate area. The feeder will cross Vandenberg Avenue underground. The 6 inch HDPE duct crossing Vandenberg Avenue underground will be installed by others. New line will terminate at existing SC- 51-2 Way-1.
