Appendix CRF - Part 3 - Northamptonshire County Council

Limit values are prescribed for certain leach parameters and total organic
carbon. The limit values vary between granular or monolithic waste forms
(LLW could be either type). The limit values appropriate for the LLW
would be established through reference to the underpinning risk
assessments for the landfill design.
Special arrangements apply to handling of asbestos bearing wastes.
Compliance with site specific authorisation conditions.
Compliance with the total tonnage limits placed on the landfill by the existing
permit (It is important in order to maintain the integrity of the existing
environmental impact assessment that the total physical capacity of the
landfill is unchanged).
Prohibition of deliberate dilution or mixing to achieve waste acceptance
criteria.
9.3 Conditions Arising from the Site Specific Risk Assessment and
Industry Practice
LLW will not be loose handled or tipped at the site.
LLW will be transported to the site in radioactive materials compliant sealed
packages and in packages suitable for handling at the landfill site.
Waste will undergo an agreed pre-acceptance, pre-notification, receipt and
disposal process in accordance with operating arrangements.
The paper work for each consignment and the waste load will be inspected to
confirm that they are consistent with the waste booked into the site.
Wastes will be placed on the same day as receipt, or will be suitably
quarantined where this is not practicable.
Wastes will be covered by at least 300m thickness of suitable cover after
each emplacement campaign or at the end of the working day such that there
is no exposed face. Sufficient cover will be used to ensure the doserate at 1
metre above the waste is less than 2 microSv/hr.
The waste will not be trafficked or compacted without a covering protective
layer of suitable cover adequate to protect the waste from exposure to the
surface.
A radiation protection plan and scheme of environmental monitoring will be
operated in accordance with agreed operating arrangements.
The maximum concentration of radioactivity in any package will be 200 Bq/g
averaged over the package and in any case not averaged over more than 4
tonnes.
The minimum concentration of radioactivity averaged in any package shall be
such that the waste is defined as low level or very low level radioactive waste.
