are identified. The severity and magnitude of the potential effect are determined based upon factors such as proximity, duration, frequency and severity. 25. The magnitude of an effect depends on how much change the receptor is likely to experience from existing conditions. The magnitude of the effect and the sensitivity of a receptor are together used to determine the significance of the ‘impact’. Where impacts are predicted to be moderate or major, they are significant in EIA terms. 26. Where any negative environmental impacts are predicted to occur, reasonable mitigation has been identified to potentially reduce the impact as far as possible. 27. The EIA was undertaken by competent experts with relevant professional qualifications and experience. 5 SES Technical Chapter Summaries 5.1 Chapter 5 Water Resources, Flood Risk, Drainage and Water Environment Regulations 28. The chapter assesses the potential effect of the construction, operation and decommissioning phases of the proposed amendments to the currently Approved Development in relation to surface and groundwater and flood risk. 29. There are no proposed changes to the water management principles and practices used within the Woodsmith Project, and surface water run-off and flooding risk will continue to be appropriately managed through safe design. This includes the submission of the following documents for approval by the Planning Authority and other relevant stakeholders including the Environment Agency and Lead Local Flood Authority, prior to the commencement of each phase of construction: • Hydrogeological Risk Assessment. • Construction and Operation Phase Ground and Surface Water Monitoring Scheme. • Remedial Action Plan. • Groundwater Management Scheme. • Construction Environmental Management Plan. • Surface Water Drainage Scheme. • Wastewater Management Scheme 30. During the operational phase, Surface Water Drainage Strategies will be adhered to at all three sites to mitigate potential surface water drainage and flood risk impacts. 31. The assessment concluded that with the continued adherence to the approved mitigation, monitoring and management plans that have been implemented throughout the construction of Woodsmith Mine, Ladycross Plantation and Lockwood Beck to date, the impacts of the proposed amendments would be negligible during the construction, operational and decommissioning phases regarding the following: • Increased sediment supply. • Direct disturbance of surface watercourses. • Accidental release of fuels, oils, lubricants and construction materials. • Increased surface water flows from site drainage. • Increased sediment supply. • Direct disturbance of surface watercourses.
