AECOM 6-2 Wheelabrator Harewood Waste-to- Energy Facility 6. Traffic and Transport Introduction This document provides the preliminary findings of the environmental assessment undertaken to date to inform the formal consultation process. It does not constitute a full Environmental Statement (ES), which will be produced as part of the Development Consent Order (DCO) application. It is intended that this chapter provides consultees with an early opportunity to provide informed comments on the work undertaken to date and its findings. The Applicant will take into account these comments when finalising the ES and DCO application. The various assessments are at differing stages of completion due to outstanding design and baseline information, and in some areas there are gaps that are highlighted along with an explanation on how this will be further developed for the ES. This approach adheres with the EIA Regulations and Planning Inspectorate Advice Note 7. This chapter of the PEIR reports the findings of an assessment of the likely significant effects on traffic and transport as a result of the Harewood Waste-to-Energy Facility (hereafter referred to as the ‘Proposed Development’). For more details about the Proposed Development, refer to Chapter 4: Proposed Development of this ES. This chapter identifies and proposes measures to address the potential impacts and effects of the Proposed Development on traffic and transport, during construction, operation and decommissioning where resolved. Further information on any mitigation required to manage the impacts of the Proposed Development will be provided in the final ES. Stakeholder Engagement Stakeholders for the Proposed Development include statutory consultees, land managers, landowners, heritage interest groups, academics and local communities. In addition to the statutory consultation process, there will be ongoing engagement with statutory and formal consultees to steer the development of the Proposed Development in terms of transport considerations. A high-level summary of responses to the Scoping Opinion can be found in Chapter 2: Assessment Methodology and Significance Criteria. Key comments relevant to this discipline are outlined below.
