31 Aug 2021: Update (31st August 2021): Consultation and virtual exhibition opened on 31st August 2021, running to 11th October 2021.  The Awel y Môr team has today published the project’s Preliminary Environmental Information Report (PEIR) which contains detailed maps and plans, plus information on the project’s expected impacts and how they will be avoided, minimised and mitigated where possible. The team is inviting people to review this report (provided with a Non-Technical Summary suitable for all readers) and to share their feedback. Statutory consultation expected to take place Q3/Q4 2021. A Preliminary Environmental Impact Report (PEIR) will be produced for the formal Public Consultation in 2021, which will set out understanding of the baseline environment, the impacts the project may have and proposed mitigations. Following responses to that consultation developers will produce an Environmental Statement that details all the work conducted through the EIA process – this will form an important part of the applications for a DCO and Marine Licence.
