The contractor will perform the following: a) prepare a site located as far as possible from transmitter and Subtasks A609 and A628; b) drill two 4 1/2-in. diameter cased holes with the bottom 10-ft. (minimum) of the casing cemented. The holes should have a 6 to 12-ft. horizontal separation and the depths should differ by 100-ft. (+ 1 foot). The shallower hole will have a minimum depth of 20-ft. The holes should be drilled in rock or coral of uniform density; c) the instrument trailer antenna should have a line-of-sight to all events and be located a minimum of 100-ft. from the cased holes; and, d) provide electrical hookup where required. The project manager, USAF/ESD will determine the need and a site location for Subtask A629 ata later date. Refer to Figure A-19, Appendix A, island plot plan. Three scientific personnel will be assigned to Subtask A629 at this location. 22-7 oon nied ’ ’ VOL II April 1969
