From page 21...
... These dilution waters must have, in each case, significantly lower average concentrations than the ppc values of the neighboring more inshore environment. The environmental ppc values computed below thus cannot be considered to represent the average permissible concentration throughout the entire volume of each of the subject marine environments.

From page 22...
... Hence the maximum permissible value for strontium 90 in the marine environment, assuming that man receives all his protein requirement from fish harvested from that environment, and assuming that this is man's only source of ingestion of radioactive materials, would be 3.2 x 10'7 nc/rnl. Since for the coastal environment we have assigned only one-tenth the maximum permissible dose to the effects of wastes from nuclear-powered ships, the ppc value for coastal water would be 3.2 x 10'8 nc/ml.
