UNITED STATES ENVIRONMENTAL PROTECTION AGENCY OFFICE OF RADIATION PROGRAMS-LAS VEGAS FACILITY P.0. BOX 15027, LAS VEGAS, NEVADA 89114 {702) 736-2969 « FTS 595-2959 - : HOV 8 1977 Colonel Charles J. Treat Defense Nuclear Agency Kirtland Air Force Base Albuquerque, NM 87115 _ . 2 Dear Colonel Treat: Mr. Bruce Church has provided me with a copy of your draft Chairman's Report and a copy of your draft Synopsized Minutes of the subject October 4-5, 1977, conference. Mr. Bernhardt and I have reviewed these drafts. Our comments are as follows: General Since there was considerable commentary on the scope and objectives of the conference, these should be clearly delineated in both documents. Presumably the objective was to determine if the existing data base is adequate to estimate the resources necessary to cleanup Runit and to delineate the initial operations plan. A secondary objective was to define what additional data should be gathered if the data base was considered inadequate. It should also be noted that the decision as to the necessity for Rimit cleanup or the extent of Runit cleanup was stated to be outside the conference scope. Summary Page 2, Item 2.f. not be used. Delete the last sentence. Plowing or mixing should We believe that this was also the group consensus. Page 3, Iteme. For the central northem area we believe that the recommendation was to conduct two cross-island traverses. Assuming an average island width of 700 feet and sample spacing of 10 meters, ' this would result in about 40 samples. This should have a fairly high _ priority in determining the relative mass for cleanup. Suggest replacing Item e with Item k. oo Page 5, Itemh. . Given the uncertainties associated with sampling only one 5~centimeter section out of each 20-centimeter vertical increment, samples should be removed and stored from each 5-«centimeter section for potential future analysis. Believe this was suggested and at one point adopted at the meeting. Lo . ‘. 8
