BBC News - Chemical weapon 'risk' at RAF Kinloss in Moray
RAF Kinloss authorities knew the public could be at risk from chemical weapons buried near the base, according to documents obtained by BBC Scotland. The Moray base is already the focus of an investigation into radioactive contamination. A 2004 land quality assessment also warned sulphur mustard chemical weapons may be present within landfill and waste areas accessible to the public.
Stashes found near Cott a while back as I recall.
