Regulation 12 Waste which may be accepted in the different classes of landfill
The operator of a landfill shall ensure that the landfill is only used for landfilling waste which is subject to prior treatment unless–
it is inert waste for which treatment is not technically feasible; or
it is waste other than inert waste and treatment would not reduce its quantity or the hazards which it poses to human health or the environment.
The operator of a landfill for hazardous waste shall ensure that only waste which fulfils the waste acceptance criteria in paragraphs 1 and 2 of Schedule 2 is accepted at the landfill.
The operator of a landfill for non-hazardous waste shall ensure that the landfill is only used for landfilling–
municipal waste;
non-hazardous waste of any other origin which fulfils the waste acceptance criteria in paragraphs 1 and 3(b) of Schedule 2; and
stable, non-reactive hazardous waste (such as that which is solidified with leaching behaviour equivalent to that of non-hazardous waste referred to in sub-paragraph (b)) and which fulfils the waste acceptance criteria in paragraphs 1 and 3(a) of Schedule 2.
Where hazardous waste of the type described in paragraph (3)(c) is disposed of at a landfill for non-hazardous waste, the operator shall ensure it is not deposited in cells used or intended to be used for the disposal of biodegradable non-hazardous waste.
The operator of a landfill for inert waste shall ensure that the landfill is only used for landfilling inert waste which meets the waste acceptance criteria in paragraphs 1 and 4 of Schedule 2.
