105 CMR, § 120.253 - Discharge by Release into Sanitary Sewerage
(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;
(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
(3) if more than one
radionuclide is released, the following conditions must also be satisfied:
(a) the licensee shall determine the fraction
of the limit in
105
CMR 120.296: Appendix B,
Table III 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
105
CMR 120.296: Appendix B,
Table III; and
(b) the sum of the
fractions for each radionuclide required by 105 CMR120.253(A)(3)(a) does not
exceed unity; and
(4) the
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
gigabecquerels) of hydrogen-3, one curie (37 gigabecquerels) of carbon-14, and
one curie (37 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 105 CMR
120.253(A).
