(a)keep an adequate record of the NORM waste which A disposes of on or from any premises under that article;

(c)dispose of the NORM waste in respect of which that article applies—
(i)subject to paragraph (3) where it applies, by burial or landfill (or transfer to a person for such burial);
(ii)by incineration (or transfer to a person for such incineration), but only to the extent that—
(aa)none of the incinerated waste has a NORM waste concentration in excess of 5 Bq/g; and
(bb)the quantity of radionuclides in the total amount of NORM waste incinerated per year does not exceed 1 x 108 Bq; or
(iii)to a waste permitted person; and
(d)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) Paragraph (3) applies to a person (“B”) to whom article 19(2)(a)(ii) or (b) applies where B intends to dispose of NORM waste under one of those exemptions by burial in landfill.
(3) B must—
(a)make a written radiological assessment of the reasonably foreseeable pathways for the exposure of workers and the public to radiation in respect of the disposal of that waste at the place of disposal;
(b)be satisfied that the assessment demonstrates that radiation doses are not expected to exceed—
(i)1mSv per year to workers at the place of disposal; and
(ii)300µSv per year to the public;
(c)provide that assessment to the chief inspector at least 28 days before the first disposal is made; and
(d)not dispose of that waste or continue to do so if the chief inspector objects in writing to that assessment.
