On 18 June, Bradbury sent a message to DMA suggesting that tunnels be developed errs for possible LASL fullscale shots during Millrace. This was followed up immediately 2 H by direction to LASL to discuss their possible requirements with H&N and see what could be done to prepare sites. Correspondence between the various information offices of the AEC at this time indicates a forthcoming public announcement on Millrace and the statement that it will be entirely underground. The statement would also say that there would be no release of radiation to the atmosphere and no off-site fallout. Albuquerque is pressuring to make the public announcement of Millrace now rather than waiting until Later due to the possible later conflict with the results of international conferences or other activities which might stir public reaction. Late in June, Bob Watt worked on the possible tunneling for LASL shots for Millrace and provided the information to Graves and Bradbury who were both at Eniwetok. Graves told Watts by message on 27 June to proceed with the construction of 2 double track tunnels on the shortest feasible time scale.
