The Sizewell C Project

I understand that when EDFE submit their DCO for Sizewell C to the Planning Inspectorate for deliberation, the documents that the case will be considered against will be EN1 and EN6.
Are there any other Planning documents that will be pertinent to the Application?
As the Sizewell C site is in the Suffolk Coast and Heaths AONB I understand that IROPI may be used to by pass the AONB designation. Would you please tell me if this is the case.

Advice given

I can confirm that, on the information currently before us, the relevant National Policy Statements are EN-1 (Energy) and EN-6 (Nuclear Power Generation). It would not be appropriate for us to advise what the relevant planning policy will be before the application has been submitted. This will be set out by the Applicant in their Planning Statement and, if the application is accepted for examination, the local authority(ies) will be invited to set out their local planning policy considerations as they relate to the proposed development in their Local Impact Report.
With regard to IROPI, this acronym is used with reference to impacts on European sites designated for nature conservation (for example Special Areas of Conservation, Special Protection Areas, Ramsar sites) that are protected under the Habitats Directive (The Habitats Regulations in the UK), not AONB. We are aware that there are a number of European nature conservation sites within the vicinity of the existing power station (and therefore, in the absence of a proposed boundary, within the likely vicinity of any proposals). For further information on this you may wish to see our Advice Note 10: Habitats Regulations Assessment relevant to nationally significant infrastructure projects: attachment 1
Alternatively, perhaps your reference to IROPI is in relation to EN1, which in paragraph 5.9.10 makes reference to demonstrating ‘public interest’ when considering development in an AONB. It will be for the applicant to present their case with regard to the ‘public interest’ (in whatever context) in their application.
