CHAPTER 5 DEBRIS CLEANUP DEBRIS CLASSIFICATION There werethree basic classes of debris identified in the Environmental Impact Statement(EIS):! a. Hazardous debris, consisting of items with hazardousradiation levels and items which were physical hazards such as dilapidated structures, derelict boats, and open manholes. b. Obstructive debris, consisting of items which interfered with the proposed use of the islands, such as concrete pads. c. Cosmetic debris, consisting of items which were neither hazardous nor obstructive but were simply unsightly. Items were classified during the Enewetak Engineering Survey and identified in the Master Index to the survey report by location, classification, planned disposition, and agency responsible for disposition. In planning the Enewetak Cleanup Project and the Enewetak Rehabilitation Program, it was originally agreed that the Defense Nuclear Agency (DNA) would removeonly hazardous debris and that the Trust Territory of the Pacific Islands (TTPI), as the rehabilitation agent for Department of the Interior (DOI, would remove obstructive debris. Cosmetic debris was not to be removed. During joint TTPI-Field Command engineering surveys in 1976, the original agreement was modified to provide that the Department of Defense would removeall obstructive debris as well as hazardous debris on the nonresidential islands, in exchange for which DOI/TTPI would accomplish an equal amount of hazardous debris removal on the residential islands of Japtan (David), Medren (Elmer), and Enewetak (Fred). The exchange benefited both agencies.It limited DOI/TTPI work to three noncontaminated southern islands; it limited Field Command’s radiological safety and control responsibilities on the nonresidential islands to cleanup project personnel; and it minimized duplication in staging and supporting work forces on the northern islands. As a result of these agreements, the Master Index was revised to indicate DNA responsibilities for removal of both obstructive and hazardous debris. Hazardous debris was further classified as to radioactivity into three _ categories. The categories were determined by the disposal method authorized by Enewetak Standard Operating Procedures? which were based on American National Standards Institute draft Standard N328- 1976, Table 13 as amended by the Department of Energy-Nevada 219
