     (a) The material is readily soluble in water or is readily dispersible biological material in water.

     (b) The quantity of all radioactive material that the licensee releases into the sanitary sewerage in 1 month divided by the average monthly volume of water released into the sanitary sewerage by the licensee does not exceed the concentration of radioactive material listed in Table III of Appendix B.

     (c) The total quantity of all radioactive material that the licensee releases into the sanitary sewerage in 1 year does not exceed 5 curies of hydrogen-3, 1 curie of carbon-14 and 1 curie of all other radioactive materials combined.

     (d) If more than one radionuclide is released:

          (1) The licensee determines the fraction of the limits in Table III of Appendix B represented by discharges into sanitary sewerage by dividing the actual monthly average concentration of each radionuclide released by the licensee into the sanitary sewerage by the concentration of that radionuclide listed in Table III of Appendix B; and

          (2) The sum of the fractions for each radionuclide required by subparagraph (1) does not exceed unity.
