Wave & Tidal Environmental Assessment
Due to the large size of the Regional Environmental Assessment, it has been split into 18 separate files plus the Non-Technical Summary, Consultation Report and Appendices. The documents are all available for public download and are also available in a large ZIP file to download in one file here . Although we are not currently consulting on the document we are still happy to hear from you, contact us and provide feedback. Please see below for the documents available to download.
REA Consultation Report (1.1MB)
This document explains the consultation process and gives information on all of the responses that RET received to the public consultation. It also outlines the main actions suggested by the consultees and any response and action the RET is taking and highlights where changes were made to the REA following the consultation.
REA Non Technical Summary (2MB)
This document is a 57 page Non-Technical Summary (NTS) of the REA. The NTS provides an overview of the key findings of the assessment, listed under each specialist topic considered. Each subsection covers the baseline (existing) data, impact assessment and potential mitigation measures. The results of each specialist investigation have been drawn together in the Summary of Key Impacts in section 5. This allows comparison and a consideration relative significance of each investigation. If you require additional detail for an area please see the relevant chapter in the Full REA below.
The table shows the chapters that are available to download, with more information about each chapter below.
