6.0 Waste Disposal History
6.0.1 The original Permit for the site was issued in 2002. The Permit was reviewed in
early 2009 and a new Permit issued in May 2009. Landfilling commenced in
2002 in a series of 5 Phases (Figure 2). The site was originally operated as a codisposal
facility in which Special Wastes were disposed of with non-hazardous
biodegradable wastes. This principle of co-disposal relies on the biological
activity in the biodegradable wastes to ameliorate the Special Wastes. Phases 1
and 2 of the site were operated by co-disposal. The use of co-disposal ended
with the implementation of the Landfill Regulations in 2004. Under the 2004
Regulations the facility became a landfill site for the acceptance of hazardous
wastes. Therefore Phases 3 onwards have received hazardous and inert wastes
only.
6.0.2 To date Phases 1, 2 and 3 have been completed capped and restored. Phase 4
is operational and Phase 5 needs to be excavated and engineered (Figure 2).
Approximately 650,000m 3 of waste has been disposed of and there is
approximately 700,000m 3 of void remaining.
6.0.3 Baseline samples of leachate and groundwater have been analysed for
radioactivity and results are given in Annex I. The baseline sampling showed no
enhancements of radioactivity in the groundwater samples. The leachate
samples showed a slight enhancement for Tritium, which is commonly found in
leachate from landfills across the UK. The levels of Tritium were lower than
those usually found in landfill leachates (Annex I).
