-13- Bair: Can you obtain the data and be specific in how we can help? Please put specific request in writing. It's difficult to deal with the issue at this meeting. The item should be on the agenda for the next meeting. McCraw: Will provide whatever information is available. Considerable discussion took place on the subject of subsurface contamination. Is it necessary to define subsurface (e.g., anything below a certain depth, perhaps beyond the depth of an IMP reading)? What numbers apply for cleanup criteria for subsurface radiological contamination? Can we provide at least broad guidance? Should we defer to the operations plan? Should surface criteria apply also to subsurface contamination? Core samples should be analyzed. Should criteria be a function of depth? of area? Should core samples be averaged? General opinions include: Anvestigate only when portions of a profile sample exceed 160 pCi/gm. Cover area (2 meters radius?) from the sample location. Four core samples should be taken to the depth of the 160 pCi/gm sample. Apply 40-80-160 pCi/gm guidance to average concentrations of transuranics in the core samples. Bair: Will attempt to word the above opinions. Bair and Wachholz agreed to draft a preliminary response, with appropriate qualifications, to Bauchspies which will address the major issues raised by DNA/JTG.
