The purpose of revising this EC (Revision 2) is to describe additional work needed to complete the original work scope (see below). Power management may need to place gravel on two power line access roads (not wider than current two-tracks) to prevent equipment (bucket trucks and other vehicles) from becoming stuck in soft road conditions. Power Management needs to continue this work to restore power to PBF-614, which houses a deep well pump. Power management proposes to place gravel on the power line access road that services circuit 57 from CITRC substation to building PBF-623. In addition, where power poles are not close enough to the road, power management proposes placing a gravel pad off the access road allowing vehicles to set up and reach the power poles. Power management will have gravel pads placed only where they cannot reach the pole from the road. Most work will occur from the access road. Power management may also need to place gravel on the access road between the substation and the new distribution pad and the control shelter pad; no off-road pads are necessary on this part of the access road. Gravel for the distribution pad and control shelter pad is included in the original scope.
