A more reasonable option fs to integrate the operations required for PL 96-205 with DOE programs in the Marshalls currently utilizing the DOE Supported vessel. As part of the on-going DOE effort, approximately 20% additional ship time support would be required during regular scheduled research cruises to Bikini on an annual basis. Two to three weeks of additional ship support would be necessary at Utirik and Rongelap every few years. These periods of time could be accomodated with some rearrangements and modifications in the current schedule. indicated for ship support. In the appendices two costs are In both cases it must be recognized that the costs are highly dependent on usage of the vessel; any modifications in the frequency of sampling required and non-predictable factor such as weather and equipment failure. One cost assumes an independent vessel is devoted entirely to work under this program. The second is the estimated shiptime cost for this program if the effort were implemented in conjunction with on-going programs. If additional Atolls are included in this monitoring program it is probable that the present support capabilities of the current research vessel could be exceeded. An additional vessel might be required to support the additional effort at other Atolls. This support is indicated as a separate item in Appendix B - Table 1 which outlines the estimated 1981 annual costs if other Atolls are included with this plan. 50
