8 MARINE WATER AND SEDIMENT QUALITY
8.1 Introduction 1.
This chapter on marine water and sediment quality was authored by Royal HaskoningDHV. The chapter describes the existing environment with regard to marine water and sediment quality and assesses the potential impacts of the proposed East Anglia THREE project during the construction, operation and decommissioning phases. Where the potential for significant impacts is identified, mitigation measures are presented.
2.
Certain elements of the assessment are informed by Chapter 7 Marine Geology, Oceanography and Physical Processes and in turn this assessment informs Chapter 10 Benthic Ecology and Chapter 11 Fish and Shellfish Ecology. Related onshore issues are considered in Chapter 19 Geology and Ground Conditions.
3.
The assessment of potential impacts on marine water and sediment quality has been made with specific reference to the relevant legislation and guidance (as presented in section 8.4.1) of which the primary source are the National Policy Statements (NPS).
8.2 Consultation 4.
5.
To inform the PEIR, East Anglia THREE Limited (EATL) has undertaken a thorough pre- application consultation process, which has included the following key stages:
Scoping Report submitted to the Planning Inspectorate (November 2012). Scoping Opinion received from the Planning Inspectorate (December 2012).
A summary of the consultations carried out at key stages throughout the proposed project of particular relevance to marine water and sediment quality are presented in Table 8.1. Due to similarities in the location, consultations undertaken for the proposed East Anglia ONE project have been considered as relevant and are also included.
