Specific immobilisation approvals
OEH issues immobilisation approvals in accordance with clause 50 of the Protection of the Environment Operations (Waste) Regulation 2005. Immobilisation approvals may either be general or specific.
Specific immobilisation approvals are issued to a nominated person for a particular waste. The approvals issued are subject to conditions which include:
The period for which the approval is valid
The treatment required to immobilise the waste, for waste that is not naturally immobilised
Testing and record keeping requirements
How waste subject to the approval may be classified for disposal – essentially the contaminants of concern can be classified on TCLP (toxicity characteristics leaching procedure) alone, the SCC (specific contaminant concentration) is not taken into account for waste classification purposes.
Any other conditions, such as waste tracking, which are required
Before applying for a specific immobilisation approval:
Investigate alternatives to immobilisation. Specific immobilisation approvals will only be issued where it is not possible to reuse, recycle or reprocess the waste. Where feasible, treatment to remove or destroy the contaminants is preferable to immobilisation.
the waste is the same as that described in the general immobilisation approval, including any restrictions, such as its method of formation;
the contaminants listed in the general immobilisation approval include all the contaminants of concern in the waste.
If there are no alternatives to immobilisation and there is no general immobilisation approval for the waste, apply to OEH for a specific immobilisation approval.
For more information on classifying waste please refer to the Waste Guidelines.
