Abstract: The Department of Defense's Naval Research Laboratory (NRL) has been tasked by the Strategic Environmental Research and Development Program (SERDP) to assess the environmental viability of the isolation of dredged material, sewage sludge, and municipal incinerator fly ash on the abyssal plains of the deep ocean. Abyssal Plains Waste Isolation (APWl) is the term given by this project to the isolation of waste on the abyssal plains. Oceaneering Technologies (OTECH) has been tasked by NRL to assess waste handling technologies regarding engineering feasibility and reliability. The first step in assessing the engineering feasibility and reliability of waste handling technologies was to identify top level or system level requirements that will have to be met by any APWl concept considered. Sources of APWl system level requirements were environmental regulations, physical and chemical characteristics of the waste streams (dredged material, sewage sludge, and municipal incinerator fly ash), weatherisite conditions, and standard references for ocean going vessels. A literature search of each of the sources was performed. The information extracted from these various sources was placed into the categories of handling, transportation, and emplacement. Systerr I approx. el requirements were then derived from this information The second step was the technical assessment of candidate waste handling technologies which was a three part process. First, through a series of patent research, brainstorming new ideas, and a methodical down-select and evaluation exercise, five concepts were chosen to be evaluated. Technical issues of these five concepts were then
