184 CHAPTER V, SECTION 1 The earth ramps used by the LSTs at Elmer and Nan required bulldozing with the arrival of each ship. Road maintenance consisted of the occasional use of the motor patrol equipment, especially after heavy storms, in order to maintain the surface. A water truck was used to allay dust during prolonged rainless periods. As a result of the fall-out caused by the Tewa event, all the base camp areas affected were decontaminated by grading. This work had to be accomplished both mechanically and manually in order to bring the radioactivity to acceptable levels. The major shops for repairing refrigeration, power-generating, and water-distillation equip- ment were located at Elmer. All such equipment was thoroughly checked through the major shops before shipment to an off-island camp. Main- tenance of this equipment at temporary camps consisted of routine servicing and incidental trouble shooting. An unusual maintenance requirement developed due to the accidental shorting of one of the 1000 KW generators in the CMR plant. The rewinding of this generator could not be accomplished with the facilities available at Jobsite, and it was therefore shipped to Honolulu where the work was a purchase order contract. performed under The steel tanks installed during Operation GREENHOUSE for storing salt and fresh water at Elmer and Fred had to be replaced prior to CASTLE and again for REDWING. Because of the relatively short life of steel tanks and their high maintenance costs, they were replaced with tanks made of redwood staves. At first, considerable leakage occurred at the seams of the wooden tanks; however, most of the leakage was eliminated by using seal coat. Due to operational requirements which did not permit removing the tanks from service, the completion of this repair work had to be postponed until the end of the Operation. Maintenance, though continuous throughout each Operation, will be intensified now that REDWING has been completed. Due to the magnitude of REDWING, equipment and facilities could not always be spared for routine work, and personnel normally engaged in servicing were assigned to higher priority jobs during the peak of activities; consequently, a considerable maintenance backlog has developed which must be accomplished shortly in order to offset deterioration economically. This ac- cummulation of routine maintenance plus the usual post-operational equipment servicing and preservation will be a much greater job than previously experienced. Page 5-3
