Appendix CRF - Part 3 - Northamptonshire County Council

Exempt and excluded wastes are not a relevant waste to the permit. It is
proposed that if wastes of less than a relevant exemption or exclusion order
are mixed in with the LLW as an inevitable result of their production then
these would also be treated as LLW. Should the RSA exemption orders
which define the boundary of Exempt and LLW wastes be revised, then the
authorisation would automatically incorporate such changes.
The waste will be a solid waste as defined under the Landfill Regulations.
Liquid wastes and slurries etc. are prohibited.
The radiological capacity will be monitored and complied with.
The waste will consist of waste material that is deemed to be contaminated
and not be primary contaminant material (such material would be normally
recoverable and hence not be a waste).
Notwithstanding the requirements of the existing permit under the Landfill
Regulations which concern acceptability of chemical hazards in respect of
hazardous waste - the waste will not be capable of generating toxic or
explosive gases, vapours or fumes that would be harmful to persons involved
in the waste process.
Notwithstanding the requirements of the existing permit under the Landfill
Regulations which concern acceptability of chemical hazards in respect of
hazardous waste – the waste will not contain pressurised gas receptacles as
defined within the Carriage of Dangerous Goods…Regulations 2004 (or as
amended).
LLW containing putrescible materials (materials liable to be readily
decomposed by micro-organisms, excluding wood and paper) will be
excluded in so far as is reasonably practicable.
Conditions for acceptance will dictate that the consignor ensures that external
non-fixed contamination levels on waste packages will be as low as
reasonably practicable throughout the process and in any case not more than
4 Bq/cm 2 beta/gamma and 0.4 Bq/cm 2 alpha averaged over an area of
300cm 2 (as derived from normal industry practice).
External dose rates throughout the process will be as low as reasonably
practicable, shall be in accordance with the transport regulations and shall
not exceed 0.01 mSv/hr (10 microSv/hr) at 1m from the waste package.
LLW with hazardous properties that would mean it would be a hazardous
waste if it were not radioactive, will comply with all the relevant conditions of
the RSA authorisation in respect of non-radiological hazards.
The capacity of the landfill is subject to a total capacity limit combined with a
series of other conditions. The total capacity limit would apply from the date
of issue until closure of the landfill or until the capacity is reached. The
landfill would receive no more LLW under the permit once the capacity limit is
reached. The capacity limit cannot be expressed as a single number
because it depends on the mixture received up to any point in time, so the
proposal is for a continuously revised capacity limit based on individual
