Weerakoon, turbines in 100 MW wind Balangoda farm and inclusion of Singhakumara mitigation in transmission lines PREFACE This document describes the environmental studies conducted for the 220 kV Mannar–Nadukuda transmission line project in Mannar, Sri Lanka. These studies were conducted between 2014 and 2016 on behalf of the Project Proponent - The Ceylon Electricity Board (CEB). This Environmental Impact Assessment (EIA), prepared according to the Asian Development Bank (ADB)’s Safeguard Policy Statement (SPS) 2009 for evaluation of project impacts and mitigation measure, comprises of the following: Environmental Management Plan (EMP) including guideline for Construction Method Statement prepared to comply with the ADB SPS 2009 and Ramsar Wetland Convention. Environment Monitoring Plan (EMoP) and Grievance Redress Machenism, including public disclosure according to ADB SPS 2009 and the Ramsar Wetland Convention guidelines. Additional Avian data - Bird Vantage Point surveys, Flight Path, and Water Hole studies conducted by Dr. Devaka Weerakoon between 2014-16; wetland ecology, and other environmental data, data on marine flora and fauna, hydrogeology and GIS mapping collected in 2014. Avian Critical Habitat Assessment Report prepared by Dr. Steve Percival and Prof. Devaka Weerakoon. Avian Collision Risk Assessment Report (2016) by Dr. Steve Percival based on avian data collected between 2014-2016 for the entire Mannar island including the 7 km long transmission line area inside the designated Ramsar Wetland area and the Wind Park
