(a) A licensee may discharge licensed material into sanitary sewerage if each of the following conditions is satisfied: (1) The material is readily soluble, or is readily dispersible biological material, in water; and (2) The quantity of licensed radioactive material that the licensee releases into the sewer in one month divided by the average monthly volume of water released into the sewer by the licensee does not exceed the concentration listed in Table III of Appendix B; and (3) If more than one radionuclide is released, the following conditions shall also be satisfied: (A) The licensee shall determine the fraction of the limit 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 sewer by the concentration of that radionuclide §11-45-72 45-72 listed in Table III of Appendix B; and (B) The sum of the fractions for each radionuclide required by subparagraph (A) does not exceed unity; and (4) The total quantity of licensed radioactive material that the licensee releases into the sanitary sewerage system in a year does not exceed one curie (thirty seven gigabecquerels) of all other radioactive materials combined. (b) Excreta from individuals undergoing medical diagnosis or therapy with radioactive material are not subject to the limitations contained in subsection (a).
