Waste Disposal: Disposal by Release into Sanitary Sewerage

(1)

A licensee may discharge licensed material into sanitary sewerage if each of the following conditions is satisfied:

(a)

The material is readily soluble (or is readily dispersible biological material) in water; and

(b)

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 10 CFR Part 20 Table 3 of Appendix B to 20.1001 to 20.2401; and

(c)

If more than one radionuclide is released, the following conditions also must be satisfied:

(A)

The licensee must determine the fraction of the limit in 10 CFR Part 20 Table 3 of Appendix B to 20.1001 to 20.2401 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 10 CFR Part 20 Table 3 of Appendix B to 20.1001 to 20.2401; and

(B)

The sum of the fractions for each radionuclide required by paragraph (1)(c)(A) of this rule does not exceed unity; and

(d)

The total quantity of licensed and other radioactive material that the licensee releases into the sanitary sewerage system in a year does not exceed 185 GBq (5 Curies) of hydrogen-3, 37 GBq (1 Curie) of carbon-14, and 37 GBq (1 Curie) of all other radioactive materials combined.

(2)

Excreta from individuals undergoing medical diagnosis or therapy with radioactive material is not subject to the limitations contained in section (1) of this rule.
