Marine Licensing in Wales

An overview of Marine Licensing in Wales is given on the NRW website here…

Under the Marine and Coastal Access Act (MCAA) 2009 it is a licensable marine activity to (amongst other things): construct any works either in or over the sea or on or under the sea bed; or carry out any form of dredging.

NRW undertake marine licensing on behalf of the Welsh Govt and must have regard for: the need to protect the environment, human health or interference with legitimate uses of the sea; and other relevant matters.

Marine Licence Applications for Tidal Lagoon Swansea Bay


Original application

The application made by TLSB in 2014 is here… The Environmental Statement submitted by TLSB applied equally to the Development Consent process and to the Marine Licensing process, so much of the material on the DCO page applies here as well.

Our initial response is here…

NRW MLT (Marine Licensing Team) said that they wouldn’t take a decision until the DCO examination had been completed.

Rather than duplicate the effort being put into the parallel DCO application, we asked the MLT if they would wait until all the DCO examination had been completed and then allow us to submit a representation summarising everything. They agreed to this and on 18 January 2015 we sent them copies of all our submissions to the DCO ExA, which can be seen on the Development Consent page here…. Our email and its attachments are also reproduced on this page under “Correspondence…”.


Further information

On a number of occasions since then TLSB have submitted new information to MLT, ie, further information not included in the original application. Such new information is supposed to be advertised, with a 6 week public consultation period. Details of NRW consultations on new information and of our responses are given below.
