Environmental Permit Applications

We have applied to the Environment Agency for the three permits it needs to operate a nuclear power station. Permits cover the work and the controls that the Sizewell C project need to put in place for construction, commissioning, operation and decommissioning of the new power station.

Water Discharge Activity (WDA) Permit | Required to allow the discharge of non-radioactive cooling water from the Sizewell C reactor back into the sea.

Combustion Activity (CA) Permit | Required to allow the operation of the diesel generators in the unlikely event the power station experiences a loss of onsite power.

Radioactive Substances Activities (RSA) Permit | Required to allow the discharge of small amounts of radioactivity from the Sizewell C reactor into the air and sea, and disposal of solid radioactive waste generated by the reactor.

The Environment Agency is now running a 12 week public consultation on those applications from 6 July – 2 October 2020.

Following the acceptance of the Sizewell C planning application for examination we have issued a list of pledges to the community in East Suffolk and published a summary of our proposals.

Sizewell C, a proposed new nuclear power station in Suffolk, has the potential to generate the reliable low carbon electricity the country needs for decades to come. It will also make a lasting positive difference to the economy in the east of England.

The project is being developed by EDF, together with our long-standing partners CGN. Our joint experience of working together on a range of projects, including constructing two EPR reactors at Taishan in China, is bringing direct benefits to Hinkley Point C and will do the same for the Sizewell C project. Additionally, this partnership has plans to develop Bradwell B in Essex.
