Western proposes to do geologic borings within our right-of-way near structures 18/5, 19/6, 21/2, 2317, 26/4, 28/4, 36/1, 37/5, 39/4 and 41/4 along the existing Casa Grande-electrical district #5 115-kilovolt transmission line. This project involves accessing each bore hole location with a auger/drill rig and light crew trucks, setting up the drill rig, drilling, collecting soil samples and breaking down the drilling setup. Existing access roads and vehicles such as pickup trucks & crew trucks will be used to bring personnel and equipment to the work areas.
