Transport 10.1 Introduction 10.1.1 This chapter of Volume 2 of the Environmental Statement (ES) presents an assessment of the transport effects arising from the construction and operation of the main development site and the construction, operation and removal and reinstatement of the associated development sites (referred to throughout this volume as the Sizewell C Project). This includes an assessment of potential effects, the significance of effects, the requirements for mitigation, and the residual effects. 10.1.2 The assessment considers the potential effects of severance, pedestrian delay, amenity, fear and intimidation, driver delay, accidents and safety and hazardous loads. 10.1.3 A description of the existing site and details of the proposals for the main development site are provided in Chapters 1-4 of this volume of the ES. Descriptions of the sites and details of the proposals for the associated development sites are provided in Chapters 1-2 of Volumes 3-9. A description of the anticipated activities for the decommissioning phase, including a summary of the types of environmental effects likely to occur is provided in Chapter 5 of this volume. A glossary of terms and list of abbreviations used in this chapter is provided in Volume 1, Appendix 1A of the ES. 10.1.4 This assessment has been informed by data presented in the Transport Assessment (Doc Ref. 8.5) and the Transport Chapter Methodology provided in Volume 1, Appendix 6F. 10.1.5 A standalone ES was prepared for the Sizewell B relocated facilities works for submission with the hybrid planning application under the Town and Country Planning Act 1990 (East Suffolk Council application ref. DC/19/1637/FUL). Chapter 10 of the Sizewell B relocated facilities ES (refer to Volume 1, Appendix 2A) included an assessment of likely significant effects associated with transport and identified mitigation specific to Sizewell B relocated facilities
