Yes – provided the Environmental Permit allows for that particular treatment and that the wastes are adequately separated from treated materials associated with the Cluster project.

Any particular activity must not extend beyond what was reasonable for the Cluster project, remembering that Cluster is a temporary activity.

It should be returned to the Hub site (see DoWCoP paragraph A3.13).

It would be prudent to use a registered waste carrier in transporting non-wastes from the Hub site to aid in this scenario i.e. it is easier to raise Duty of Care transfer notes than enter in to a new contract with a registered waste carrier to return the load. (There is no need to use transfer notes for material considered to be non-waste – it is recommended that you do not use transfer notes as Delivery tickets).

Yes. The Cluster concept recognises that opportunist sites may appear once the Hub site is established and provides a lower cost opportunity for developing land, this may include Donor and / or Receiver sites.

The defined Cluster project would then have to be re-defined to include the opportunist site (or sites). See Watch Point 17.

Yes – provided the contingency arrangements and contracts identify who is responsible for it, what will happen to it and that sufficient funds are in place to deal with it satisfactorily.

The mass balance across the sites needs to aim for this surplus amount to be as small as possible in the first instance (see paragraph A3.10).

The Cluster concept recognises that new sites may be subsequently added to a project and this can include an additional Receiver site that has a need for it.

No. See Watch Point 15. The process should:

1. Set your specification for suitability based upon a site specific risk assessment for the receiver site.
2. Check whether or not the levels of any contaminants in that spec are above hazardous waste thresholds.
3. If they are then modify the specification to reduce the acceptable level for those contaminants to below the hazardous waste threshold.
