The Radioactive Substances Exemption (Northern Ireland) Order 2011

Conditions in respect of aqueous radioactive waste in article 15

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

(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—

(i)

the value shown in column 3 of Table 4; or

(ii)

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.
