Eagle eyed observers of the IPC process have spotted a change to Covanta Flood Risk Assessment – Please Click Here to view. It is now proposed that domestic and process foul water will be treated on site and discharged via the surface water drainage system into Mill Brook and Stewartby Lake – and not via the Stewartby Treatment Works. Covanta would not be responsible for the Surface Water Drainage system but O & H Properties. The plant is in flood zone 3 and the Covanta application attempts to avoid exception testing by raising the plant 3 metres. Covanta state they have advised the Environment Agency – as obviously it impacts on their permit application. However there is no mention of advising the Internal Drainage Board who are responsible for Mill Brook and Stewartby Lake.
MMAG are looking into this further.
