Appendix CRF - Part 3 - Northamptonshire County Council

Summary of the Environmental Impacts of the Proposal
S27 The risk from radioactivity has been assessed using a conservative predictive
model. The model has been used to calculate the capacity of the landfill for
radioactivity that would result in a risk of less than one in a million per year to the
public in the long term and the capacity that meets the dose criteria set for the
unlikely circumstance of future human intrusion into the waste.
S28 In practice the risk will be even further reduced through good operating practices
and future management arrangements, but these are not assumed by the model.
S29 An assessment has been carried out of the exposure of the landfill workers which
shows that exposures can be maintained below a dose criterion of 1 mSv/yr (the
dose limit for workers is 20 mSv/yr). This has been confirmed by advice
received from the Radiological Protection Advisor for the site, the HPA (ref 16).
S30 The following list summarises the overall impact of the LLW proposal on the
existing environmental impact statement for the landfill site.
Impact to Groundwater An insignificant risk from
pollution
Impact to Surface Water An insignificant risk from
pollution
Impact to Landscape No change in the landform
Traffic Impact No additional traffic, very low
risks from traffic incident
Impact from Noise No additional noise
Impact to Ecology No additional landtake,
insignificant risk to animals.
Impact to Air Quality An insignificant risk from
release to atmosphere
Impact to Human Health Insignificant risk in the long
and short term
Archaeology No impacts identified
Proposed Authorisation Conditions
S31 The application contains a series of proposed authorisation conditions which are
subject to agreement with the Environment Agency. A proposal is made to
reflect certain conditions from the existing landfill permit/risk assessment into the
LLW authorisation in order to ensure consistency with current limits and
standards.
Application for disposal of LLW including HV-VLLW under RSA 1993,
