 25th January 2019 - Extension of consultation deadline for Transboundary Environmental consultation on proposed Wylfa Newydd nuclear power plant following Horizon Nuclear announcement last week:

The consultation deadline for the transboundary environmental consultation on the proposed Wylfa Newydd nuclear power plant in the UK, from close of business, 25th January to close of business on Friday, 15th February 2019.

Following the announcement last week that Horizon Nuclear Power was suspending its UK nuclear development programme, including plans for the proposed Wylfa Neywdd plant in Anglesey, North Wales, the Department of Housing Planning and Local Government sought clarification from the UK Planning Inspectorate on the implications of the announcement for the transboundary environmental consultation with Ireland.

 Notwithstanding the announcement by Horizon Nuclear Power, the UK Planning Inspectorate has confirmed that the development consent application (planning application) for the Wylfa Newydd plant has not been withdrawn by the applicant, and it will be continuing with its assessment of the application for the Wylfa Newydd plant as normal. Accordingly, the transboundary consultation between Ireland and the UK will continue with an extended deadline to afford additional time to those who wish to make a submission to do so at this important stage in the process.

 Anyone intending to make a submission is asked to make them to this planning authority, on or before the new closing date - close of business on Friday 15 February 2019.
