The extent to which each Authority is liable to contribute to the Unitary Charge will need to be addressed. This may be on a straight tonnage basis or on a composition of the waste supplied to the PFI Contractor.
Where the Service is deficient or there are incidences of deductions, there may be an abatement to the Unitary Charge or there may be increased costs due to the alternative costs of disposal. Deductions from payments may be incapable of individual attribution to any particular Authority and will need to be apportioned on an agreed basis across the payments. Areas where direct attribution can be made will need to be discussed and settled.
To the extent that defaults can arise in relation to a single Authority (as opposed to across all Authorities), the relevant triggers for remedies will need to be settled on an individual and aggregate basis.
