This video features a MOD contractor talking about the cleanup of the Atomic Weapons Establishment site in suburban Cardiff. The cleanup took place some years ago. The contractor explains how stakeholders were engaged and kept informed about the project.
It interesting to compare this with the more recent situations at sites such as Dalgety Bay etc which have been typified by a lack of constructive stakeholder engagement and an un-willingness to address and accept liability for historic contamination.
I suspect a driver for more positive behaviours is the need to for MOD to realise as much money as possible for sites that are being sold for redevelopment as opposed to alienated sites which are viewed as liabilities.
The need to find resource savings has means that far less money is available for to remediate polluted sites let alone stakeholder engagement.
