Application for a variation of an environmental permit under the Environmental Permitting (England and Wales) Regulations 2016
We've received applications to vary a permit from NNB Generation Company (HPC) Limited. Type of regulated facility: Water Management Zones and effluent treatment units
Address of regulated facility: Construction site at Hinkley Point C power station, Near Bridgwater, Somerset, TA5 1UD Receiving environment: Severn Estuary Application number: EPR/JP3122GM/V006 Effluent type: Trade effluent consisting of pumped groundwater
Volume: 20 litres per second
The proposal is to vary the permit to reduce the volume of
groundwater discharged to the estuary, to discharge the
groundwater without treatment and vary the discharge point
from the foreshore outfall to a new outfall at the seaward
end of a temporary jetty.
Application number: EPR/JP3122GM/V007
Effluent type: Trade effluent consisting of tunnelling effluent
and muck bay drainage
Volume: 30 litres per second plus rainfall dependent surface water runoff
The proposal is to vary the permit to include the discharge of tunnelling effluent & muck bay drainage via a new outfall at the seaward end of a temporary jetty. The tunnelling effluent will be generated through the construction of the power station cooling waters system tunnels. It will include groundwater and contain low concentrations of soil conditioning chemicals. The muck bay drainage will consist of leachate from the tunnelling spoil containing low concentrations of soil conditioning chemicals and low volumes of groundwater, as well as a rainfall dependant element of surface water runoff from the muck bay curtilage.
