Detail of outcome

NNB Generation Company (Sizewell C) Limited applied for 3 environmental permits that it would need to operate its proposed new nuclear power station at Sizewell, Suffolk.

The Environment Agency consulted on the applications from July to October 2020 and on its proposed decision and draft permits from July to September 2022.

They have assessed the 3 permit applications and considered the responses they received from both consultations. They concluded that they should issue all 3 permits and published the final decision in March 2023.

The Environment Agency considers that the limits and conditions in the permits are suitable to protect people and the environment.

Consultation description

In May 2020, NNB Generation Company (SZC) Limited applied to the Environment Agency for 3 environmental permits to operate Sizewell C. We consulted on these applications from July to October 2020. We have come to a proposed decision on whether we should issue these permits, and if we do what conditions they should include.

The permits are to:

  • dispose of and discharge radioactive waste
  • operate standby power supply systems using diesel generators
  • discharge cooling water and liquid effluent into the North Sea

Our proposed decision is that we should issue all 3 permits. The conclusions of other assessments support our view, including these 4:

  • Radiological Impact Assessment
  • Habitats Regulations Assessment
  • Countryside and Rights of Way Sites of Special Scientific Interest assessment
  • Water Framework Directive

We want your views on our proposed decision, draft permits and supporting documents. We will consider your views before we make our final decision.

We welcome everyone’s views, for example from:

  • the public
  • the energy industry
  • academics with an interest in nuclear power, energy or the environment
  • non-governmental organisations
  • any other organisation or public body

We will publish our final decision in early 2023.
