Our decision
Today we have issued three new environmental permits to NNB Generation Company (Sizewell C) Limited for a new nuclear power station at Sizewell in Suffolk.
The permits are required for the station to operate and will allow it to:
- dispose of and discharge radioactive waste (radioactive substances activity permit)
- operate standby power supply systems using diesel generators (combustion activity permit)
- discharge returned abstracted seawater (from the cooling water system and 2 fish recovery and returns systems) and other liquid trade effluents (including treated sewage effluent) to the Greater Sizewell Bay – North Sea (water discharge activity permit)
NNB Generation Company (Sizewell C) Limited applied to the Environment Agency for three environmental permits in May 2020. We consulted on the application from July to October 2020 and on our proposed decision and draft permits from July to September 2022.
Each of the three permits is an important regulatory permission that the company requires to operate Sizewell C nuclear power station. They include the limits and conditions that the company needs to put in place to ensure high standards of environmental protection during commissioning, operation and decommissioning.
