The Examining Authority has taken the decision, with advice from Anglian Water, to postpone the accompanied site inspection which was due to take place on 8 January.

This is due to severe groundwater saturation around the site as a result of the severe winter storm events and heavy rainfall which has led to significantly higher than average flows. During events such as these when a working site is required to operate outside the normal parameters additional measures are implemented.

These measures include the suspension of any access to visitors and all non-essential personnel whilst the Applicant's operational teams deal with this event.
