Jim Reeves is ARPA will retain its advisory committee (the ad hoc group for detection of nuclear detonations) on test detection and identification and this committee is chaired by Richard Latter with membership of Frank Press, Kenneth Watson, Allan Donovan, Jack Oliver, Walter Munk, Hugo Bernioff, John Tukey, Roland Herbst, and Conrad Longmeir. Details of350 KTr Bots at NTS have already been tentatively determined with the first shot being a nuclear test in area 15 in Granite, the second shot being nuclear in tuff in tunnel] U128, and the fhird soins a HE shot in tuff NeVeI~ Cirect AS moteet \ere) also in tunnel UI2B. } As for the seismic decoupling shots, Starboard states that it is his understanding that the Hockley site has the approval of all concerned. Planning and engineering for three planned scaling shots at Nevada includes a .25KT test in neve Cived) Ul2e03.a ; [.2KT test in UIl2e03, and a 40 to 50 KT test in Ul 2e07.f As for the readiness program called Succatash, Star- board states " it appears now that Succetash activities and expenditures for NTS construction and procurement should be stopped immediately except for completion of raw digging for the Ul2eo07 drift and vertical shaft. (If there is any other Succetash effort that may contribute directly to the seismic program, it should be made known to me). | would plan therefore to direct shortly that the necessary action be taken to terminate such activity and that the funds concerned be diverted to cover the initial funds of the seismic improvement program. | request that ALO advise me at the earliest practical time as to the savings that can be accomplished in FY {960 thereby and the amount required for FY 1960 seismic improvement activities." tn his reply to the message Harold Brown of LRL comments on the proposed soismic improvement activities and in particular discusses the state of
