The Environment Agency has launched a public consultation on an application from NNB Generation Company (HPC) Limited to change part of Hinkley Point C’s environmental permit relating to the operation of its standby diesel generators.
This consultation is not about construction activity on site. It relates specifically to the permit required for combustion activities during the operation of the power station, including the diesel generators, associated fuel storage tanks and interconnecting pipework that would be used in the event of a loss of off site power.
According to the Environment Agency, since the permit was originally granted in 2013, several design changes have been made. The proposed variation would allow the installation of additional back up generators and changes to those already permitted, with the aim of improving the site’s resilience in the event of a loss of off site power.
The Environment Agency has stated that it will only issue a varied permit if it is satisfied that the permit will ensure a high level of protection for both the environment and human health, and that the activities will not give rise to any significant pollution.
Who the consultation is for
The consultation is aimed at:
- Members of the public
- Communities local to the site
- Statutory consultees
- Academics with an interest in nuclear power, energy production or the environment
- Non governmental organisations
The Environment Agency has also made clear that comments from any other interested parties are welcome.
