... where the accumulation would be negligible, the minimum necessary dilution volume will be obtained by dividing the partial permissible concentration for the particular subdivision of the marine environment into the amount discharged per start-up. For the discharge into a restricted segment of the sea having only slow exchange with the open ocean waters, more complex procedures, discussed later, must be followed.
