16.—(1) A person (“A”) to whom article 15(1) applies must—
(a)subject to paragraph (2), dispose of the waste in respect of which that article applies—
(i)directly into a relevant river or the sea;
(ii)to a relevant sewer; or
(iii)to a waste permitted person.
(b)keep an adequate record of the waste which A disposes of from any premises under that article; and
(c)allow the chief inspector access to such records or such premises as the chief inspector may request in order to determine that all of the conditions that apply to A in respect of that article are complied with.
(2) In respect of disposals of aqueous non-Table 3 waste disposed from the premises, A may not use both of the disposal routes described in paragraphs (1)(a)(i) or (ii) in a year and where—
(a)A uses the route in paragraph (i), the conditions in paragraph (3) apply to A; or
(b)A uses the route in paragraph (ii), or A does not use the route in either paragraph (i) or paragraph (ii), the conditions in paragraph (4) apply to A.
(3) Where this paragraph applies, A must ensure that—
(a)in respect of any aqueous non-Table 3 waste which A disposes of, the concentration of radioactivity does not exceed the value shown in column 2 of Table 4; and
(b)in respect of the total amount of aqueous non-Table 3 waste which A disposes of from the premises in a year, the quantity of radioactivity does not exceed the value shown in column 4 of Table 4.
(4) Where this paragraph applies—
(a)where any of the aqueous non-Table 3 waste disposed of from the premises in a year has a concentration of radioactivity which exceeds the value shown in column 2 of Table 4, A must not, in respect of the total amount of aqueous non-Table 3 waste which is disposed of from those premises in a year, dispose of a quantity of radionuclides which exceeds—
(i)1 x 108 Bq for the sum of the following radionuclides: H-3, C-11, C-14, F-18, P-32, P-33, S-35, Ca-45, Cr-51, Fe-55, Ga-67, Sr-89, Y-90, Tc-99m, In-111, I-123, I-125, I-131, Sm-153, Tl-201; and
(ii)1 x 106 Bq for the sum of all other radionuclides;
or
where all of the aqueous non-Table 3 waste disposed of from the premises in a year has a concentration of radioactivity which does not exceed the value shown in column 2 of Table 4, A must ensure that, in respect of the total amount of such waste disposed of from the premises in a year, the quantity of radioactivity does not exceed—
the value shown in column 3 of Table 4; or
the quantity in sub-paragraph (a).
(5) In this article, “aqueous non-Table 3 waste” means aqueous radioactive waste which is not described in an entry in column 1 of Table 3.
