quantities, methods of preparation, and transportation distances.
Assuming the work will be started in late 1975, these estimates reflect

Major factors influencing the costs in the ocean dumping and Conus
disposal options are material preparation and transportation distance.
In the crater disposal option, the contaminated materials are left on
Runit. Transportation requirements are minimal for this option and no
particular preparation of materials is required. Material preparation is
a major factor in the crater entombment option, although transportation
requirements are minimal. The option calling for stockpiling of contaminated materials on Runit is a temporary measure, and ultimately
involves the cost of one of the other options.
Material quantities vary strongly among the different cases for soil
that is removed, but is constant among cases for radioactive scrap.
Measured estimates of these quantities are tabulated as follows (Engineering
