Six As part of the works undertaken in support of the Moray West Onshore Transmission Infrastructure (OnTI) waterbodies are assessed as being of Moderate or worse status overall, while four are assessed as being of Good overall Environmental Impact Assessment (EIA), this technical appendix presents detailed results of the desktop studies to status (Scottish Environment Protection Agency [SEPA], 2017). Table 2.1 below presents detailed information on the establish the existing baseline hydrological and hydrogeological conditions within the study area. The detailed WFD condition, the future objectives and associated mitigation measures for each of these 10 waterbodies. information presented on Water Framework Directive (WFD) Classifications and Water Resources within this report informs the summary baseline information and the assessment of potential and residual effects in Chapter 5: Hydrology, Table 2.1: Detailed WFD Baseline Information Hydrogeology and Geology of the EIA Report. Background information on the approach to the assessment, including study area and data gathering methodologies, are also presented in Chapter 5 of the EIA Report for reference.
