SECTION 7Exemption for disposing of aqueous radioactive waste

Conditions in respect of aqueous radioactive waste in paragraph 2122

1

The conditions referred to in paragraph 21(1) are that A must—

a

subject to sub-paragraph (2), dispose of the waste to which that paragraph 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 the premises under that paragraph,

c

in respect of the disposal of aqueous non-Table 6 waste, comply with sub-paragraph (3) or (4) as appropriate, and

d

allow the regulator access to such records or such premises as the regulator may request in order to determine that all of the preceding conditions are complied with.

2

In respect of aqueous non-Table 6 waste disposed of from the premises, A must not use both of the disposal routes described in sub-paragraph (1)(a)(i) and (ii) in a year and where—

a

A uses the route in sub-paragraph (1)(a)(i), the conditions in sub-paragraph (3) apply to A, or

b

A uses the route in sub-paragraph (1)(a)(ii), or A does not use the route in either sub-paragraph (1)(a)(i) or (ii), the conditions in sub-paragraph (4) apply to A.

3

Where this sub-paragraph applies and A disposes of the aqueous non-Table 6 waste directly into a relevant river or the sea, A must—

a

in respect of any aqueous non-Table 6 waste which A disposes of, ensure that the concentration of radioactivity does not exceed the value specified in column 2 of Table 7, and

b

in respect of the total amount of aqueous non-Table 6 waste which A disposes of from the premises in a year, ensure that the quantity of radioactivity does not exceed the value specified in column 4 of Table 7.

4

Where this sub-paragraph applies and A disposes of the aqueous non-Table 6 waste to a relevant sewer (or only to a waste permitted person), A must ensure that, in respect of the total amount of aqueous non-Table 6 waste which is disposed of from those premises in a year, the total quantity of radioactivity does not exceed—

a

where any of that waste has a concentration of radioactivity which exceeds the value specified in column 2 of Table 7, the value in sub-paragraph (5), or

b

where none of that waste has a concentration of radioactivity which exceeds the value specified in column 2 of Table 7, the value in sub-paragraph (5) or (6).

5

The value referred to in sub-paragraph (4)(a) and (b) is—

a

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

b

1 x 106 Bq for the sum of all other radionuclides.

6

The value referred to in sub-paragraph (4)(b) is the value specified in column 3 of Table 7.

7

In this paragraph, “aqueous non-Table 6 waste” means aqueous radioactive waste which is not described in an entry in column 1 of Table 6.
