Our priorities and focus
Radioactive substances regulation – including discharges to the environment and radioactive waste management/disposal Industrial processes Conventional wastes – water, solids Conventional discharges – water, liquid wastes Construction associated permitting Wider issues – resource usage
SLIDE 4
My “resources”
2 full time Nuclear Regulators 2 full time Environment Officers Access to the wider expertise of the Environment Agency eg flooding, legal services, waste management expertise Close work with other regulators including HSE,NII and DNSR on common issues
SLIDE 5
It’s not just about discharge limits!
Limits – RSA60, RSA93, EPR10 How limits are met depends on: plant and equipment – abatement, filtration Processes – effluent treatment Maintenance of all environmentally important plant Upgrades and replacements Managing discharges – BPM, BPEO – BAT

Key environmental discharges
Aqueous – Pangbourne Pipeline, “trade wastes”, Aldermaston Stream – north ponds Airborne – stack discharges Alpha Beta/gamma
