4. Should Epidemiology Resources, Inc. base its dose calculation upon any dietary assumptions other than those used by the Lawrence Livermore National Laboratory, paralle] calculations using the Lawrence Livermore National Laboratory dietary assumptions also should be included so that the source of any differences due to the assumed diet is clear. We must observe that it is our belief that obtaining 40 environmental samples from Bikini Atoll is not required by the court agreement and, further, is of dubious scientific or technical merit. Nevertheless, we are sensitive to the desire of the Bikini people for site confirmation and we therefore agree to accommodate their perceived needs. We must observe also that the court agreement requires review by a single scientist. Because you believe that a small team is required to comprehensively review the data, and perform related tasks, we have agreed to your request so that there will be absolutely no question of our having provided every resource needed to perform this task. Please understand that if you wish to alter the distribution of time among the three principal investigators (without exceeding the total amount allotted to them by contract) this would be acceptable to us. As stated in previous letters dated January 22, 1981 and March 31, 1981, the Bikini people must formally acknowledge that execution of this contract with Epidemiology Resources, Inc. constitutes full and complete compliance by the Department of Energy in fulfilling the Department's sole outstanding obligation under the terms of the Memorandum Agreement settling the litigation. Inasmuch as this contract will be between the Department of Energy and Epidemiology Resources, Inc., and since your Jetter-proposal of May 26, 1981, is neither on Epidemiology Resources, Inc. letterhead nor signed by an authorized Epidemiology Resources, Inc. officer, a proposal from Epidemiology Resources, Inc. addressed to the Department of Energy and signed by an Epidemiology Resources, Inc. official will be needed in order to comply with Departiental procurement requirements. We Jook forward to receiving a proposal from Epidemiology Resources, Inc. Written agreement on the condi- tions and procedures set forth above can be either incorporated directly into the proposal or set forth in a letter which will become part of any signed agreement. Please call us if you have any questions. Sincerely, Stephen H. Greenleigh Acting Deputy Assistant Secretary for Environment, Safety and Health Environmental Protection, Safety and Emergency Preparedness
