(1) the material is readily
soluble, or is readily dispersible biological material, in water;
(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
105
CMR 120.296: Appendix B,
Table III; and

radionuclide is released, the following conditions must also be satisfied:
(a) the licensee shall determine the fraction
of the limit in

total quantity of licensed or other radioactive material that the licensee
releases into the sanitary sewerage in a year does not exceed five curies (185
