Public consultation – Hinkley Point C variation to an environmental permit

The Environment Agency is responsible for regulating environmental protection at nuclear sites, ensuring that people and the environment are properly protected.

NNB Generation Company (HPC) Ltd needs environmental permits from us to cover the work and the controls that it needs to put into place for construction, commissioning, operation and decommissioning of any new power station.

What’s happening now?
Hinkley Point C is applying for a variation (change) to an environmental permit it holds for work on its construction site near Bridgwater, Somerset.
The company wants to change existing, and add new, discharges of trade effluent to the construction water discharge activity permit. These are related to testing of the site’s fire hydrant system and cold commissioning activities.
