Environment Agency chiefs want the public to air their views on how a Westcountry nuclear power station should operate.
The Agency has begun a public consultation on its draft decisions for three environmental permits for Hinkley Point in Somerset.
Each permit is a key regulatory permission that is required to operate the power station.
Agency bosses will decide whether the permits should be issued and, if so, what their conditions should be.
If granted, the permits would allow the power station to discharge and dispose of radioactive wastes, discharge cooling water and liquid effluents into the Bristol Channel and operate standby power supply systems using diesel generators.
A string of public drop-in sessions are due to be held later this month.
EDF Energy and Centrica have teamed-up to run the operation.
Their joint venture company, NNB Generation Company Limited, applied for the permits in July last year.
The Agency has consulted on and assessed the applications and considers that the permits could be issued subject to the limits and conditions specified to ensure that people and the environment are properly protected.
As part of the 13-week consultation a number of public surgeries will be held, where people can arrange to meet an Environment Agency specialist to discuss the draft decision documents.
Brian Payne, nuclear new build project manager for the Environment Agency, said: "We will make sure that any new nuclear power stations in England and Wales meet high standards of environmental protection and waste management.
"Our draft permits are included in the consultation documents and we've set out our reasoning in the draft decision documents.
"People now have a further opportunity to comment or provide information on our draft decisions.
"Our consultation closes on November 9, so there is plenty of time to get responses to us."
