Feer DEFENSE NUCLEAR AGENCY FIELD COMMAND KIRTLAND AIR FORCE BASE, NEW MEXICO 87115 ss aeye3 BOD as FT MOVEMBER '777 SUBJECT: Bair Committee Recommendation SEE DISTRIBUTION 1. The report of the committee of consultants which met at Nevada Operations Office on 15-17 August 1977, recommended that more specific guidance for application of the cleanup criteria at plutonium levels between 40 and 400 pCi/g be developed for the Task Group commander. 2. Criteria available for guidance are: a. The EIS (Section 5, Para 5.5.3.2). "Boken, Lujor, and Runit plutonium concentrations greater than 400 pCi/g would be excised and all other concentrations between 400 and 40 pCi/g would be dealt with on an individual basis as described in AEC Task Group Report. Concentrations of less than 40 pCi/g would not be disturbed." b. The OPLAN 600-77 (Tab E to Annex C). Excise all areas exceeding 400 pCi/g, whether surface or subterranean. When en area of one-half hectare exceeds 100 pCi/g, excise to some lower level. When an area of one-quarter hectare exceeds 40 pCi/g, excise to some lower level. In no case is the lower level to be below local background. This is the guidance which the consultant committee found to require clarification. 3. Additional information. a. The AEC Task Group Report provides guidance for making the 40-400 pCi/g case~by-case evaluation as follows: "a, Islands with soil levels in the above range may be divided into two categories, those of sufficient size for construction of permanent houses, and those that are not."
