maintaining a continuing surveillance of the resicual radioactivity, including that which is in the environment and that which is collected and placed on land, in craters and in the lagoon. The guidelines for radiological cleanup recommended by AEC/ERDA are based on Federal Standards, and are designed to provide the lowest practicable radiation dose to the future inhabitants of Enewetak Atoll. ‘ Accordingly, it is the purpose of the Defense Nuclear Agency, hereinafter referred to as 'DNA,"' as represented by the Deputy Director for Operations and Administration, DNA, and the Energy Research and Development Administration, hereinafter referred to as "ERDA,'' as represented by the Assistant Administrator for Environment and Safety, to enter into this agreement to define the technical support ERDA is to provide DNA and likewise to define the support DNA is to provide ERDA and its contractors during the time DNA is actively engaged in cleanup operations at Enewetak Atoll. The determination as to when the DOD cleanup activities. have been successfully completed will be a joint DNA/ERDA decision. When determination has been made that the DNA cleanup phase is complete or upon transfer of the base support activity to another agency, whichever comes first, DNA support responsibilities on Enewetak will terminate and continued support for ERDA and DNA activities must then be obtained from other sources. Thus, the long-term radiological surveillance and necessary actions by both agencies deriving therefrom must be the subject of subsequent agreements. The obligations assumed by either party under the terms of this agreement are contingent upon the funding of the proposed cleanup project by the Congress. If no funds are made available or funds should cease to be
