  "text": "(1) A person (“A”) to whom article 15(1) applies must—\n(a) subject to paragraph (2), dispose of the waste in respect of which that article applies—\n(i) directly into a relevant river or the sea;\n(ii) to a relevant sewer; or\n(iii) to a waste permitted person.\n(b) keep an adequate record of the waste which A disposes of from any premises under that article; and\n(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.\n(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—\n(a) A uses the route in paragraph (i), the conditions in paragraph (3) apply to A; or\n(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.\n(3) Where this paragraph applies, A must ensure that—\n(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\n(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.\n(4) Where this paragraph applies—\n(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—\n(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\n(ii) 1 x 106 Bq for the sum of all other radionuclides;\nor\n(b) 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—\n(i) the value shown in column 3 of Table 4; or\n(ii) the quantity in sub-paragraph (a).\n(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.",
