5.8 Environmental Radioactivity Monitoring
5.8.1 The following outline arrangements are proposed and will be detailed in the
operating arrangements for the process which will be developed if authorisation
is approved. The monitoring under the Environmental Permit is described in
detail in a series of Monitoring and Action Plans (MAPs). The MAPs set out the
parameters, frequencies, methodologies and reporting of monitoring for the
landfill. Contingency action plans are included in the event that a limit specified
in the Permit is exceeded. It is anticipated that radiological monitoring will be
added to the MAPs.
5.8.2 The following environmental radiological monitoring is proposed:
Annual radiochemical analysis of groundwater to current monitoring
schedules as described under the existing permit for several existing
boreholes close to the site. Analysis would be for gamma spectrometry,
gross alpha / beta in waters and 3 H in aqueous samples.
Annual radiochemical analysis of leachate. Analysis would be for gamma
spectrometry, gross alpha / beta in waters and 3 H in aqueous samples.
Quarterly radiochemical analysis of surface water discharge. Analysis
would be for gamma spectrometry, gross alpha/beta in waters and 3 H in
aqueous samples.
Annual radiochemical analysis of the landfill gas flare stack emission for
the radioactive gases identified in the risk assessment.
Quarterly radiochemical analysis for dust deposited on a powered static
air sampler paper at one predominantly downwind location on the site
boundary to include gamma spectrometry and gross alpha/beta. (This
would be baselined against equivalent samples taken in the period prior
to first waste receipt).
Annual analysis of randomly selected surface soils from four points
around the site boundary to include gamma spectrometry and gross
alpha/beta. (This would be baselined against equivalent samples taken in
the period prior to first waste receipt).
