requirements for water resources and flood risk in the NPS is detailed in the overarching statement for Energy EN-1 (DECC 2011a) and summarised in Table 21.4 below.
Table 21.4 NPS assessment requirements NPS requirement
Where the project is likely to have effects on the water environment, the applicant should undertake an assessment of the existing status of, and impacts of the proposed project on, water quality, water resources and physical characteristics of the water environment as part of the ES or equivalent.
The ES should in particular describe: The existing quality of waters affected by the proposed project and the impacts of the proposed project on water quality, noting any relevant existing discharges, proposed new discharges and proposed changes to discharges.
Existing water resources affected by the proposed project and the impacts of the proposed project on water resources, noting any relevant existing abstraction rates, proposed new abstraction rates and proposed changes to abstraction rates (including any impact on or use of mains supplies and reference to Catchment Abstraction Management Strategies).
Existing physical characteristics of the water environment (including quantity and dynamics of flow) affected by the proposed project and any impact of physical modifications to these characteristics.
Any impacts of the proposed project on water bodies or protected areas under the Water Framework Directive and source protection zones around potable groundwater abstractions.
Applications for energy projects of one hectare or greater in Flood Zone 1 in England or Zone A in Wales and all proposals for energy projects located in Flood Zones 2 and 3 should be accompanied by a flood risk assessment (FRA).
Further guidance can be found in the Practice Guide which accompanies Planning Policy Statement 25 (PPS25).
EN-1 Section 5.7.4 and 5.7.6
A flood risk assessment is to be updated for East Anglia THREE and will be presented as an Appendix to the final ES.
NPS reference
EN-1 Section 5.15.2

The potential impacts to water resources and water quality are included within section 21.6. A WFD Compliance Assessment will be provided in an appendix to the final ES.
EN-1 Section 5.15.3
The existing environment is discussed in section 21.5 and potential impacts during construction and operation are discussed in Section 21.6. A WFD Compliance Assessment will be provided in an appendix to the final ES.
