A licensee may discharge licensed material into sanitary sewerage if
each of the following conditions is satisfied:
(1) the material is readily soluble in water, or is readily
dispersible biological material;
(2) the quantity of licensed or other 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 §336.359 of this title (relating
to Appendix B, Annual Limits on Intake (ALI) and Derived Air Concentrations
(DAC) of Radionuclides for Occupational Exposure; Effluent Concentrations;
Concentrations for Release to Sanitary Sewerage);
(3) if more than one radionuclide is released, the licensee
shall determine the fraction of the limit in Table III of §336.359 of
this title 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 listed in
Table III of §336.359 of this title; the sum of the fractions for all
of the radionuclides released shall not exceed one; and
(4) the total quantity of licensed and other radioactive material
that the licensee releases into the sanitary sewerage in a year does not exceed
five curies (185 gigabecquerels) of hydrogen-3, one curie (37 gigabecquerels)
of carbon-14, and one curie (37 gigabecquerels) of all other radioactive materials
combined.
