The Navy Project Manager for coordination and execution of DOD responsibilities for rendering logistics support to this survey is Commander, Pacific Missile Test Center, Pt. Mugu, __ California. a. PHASE I. Initially, support will be provided for a photographic survey of eleven (11) atolls and two (2).islands in the Northern Marshall Islands utilizing a DON EC-121 aircraft. This platform has been specially configured to receive DOE-provided high resolution and infra-red capable cameras, plus additional peripheral support equipment. (1) Phase I will be accomplished under the operational direction of the Project Manager (COMPMTC), in accordance with the technical direction and advice of the On-Site DOE representative and the terms of this MOA. (2) COMPMTC will promulgate an appropriate Operations Directive for the accomplishment of the Phase I mission. b,. PHASE II. Utilizing data gathered from the foregoing photographic.survey, an Aerial Radiological Survey of eleven (11) atolls and two (2) islands will be conducted by means of SH-3G helicopters equipped with DOE-provided radiation detection and recording instrumentation. The helicopters will normally operate ship which will, tics support. from USNS WHEELING (TAGM-8), in addition, a base support provide a wide range of logis- Flying relatively. precise tracks at specified altitudes and air speeds, the data collected will be reduced and result in the radiological documentation and character- ization of the eleven (11) atolls and two (2) islands in the Northern Marshalls, for later use as deemed appropriate by DOE and DOI _in ongoing rehabilitation and resettlement programs.
