PROJECT OBJECTIVE AND RATIONALE Objective: to build a hydropower plant on the Selenga river Rationale: • Domestic energy needs – Lack of generation capacity and growing electricity imports – Energy security – Lack of regulating capacity • Water/flood management • International climate change agenda – Mongolia NDC at COP21 Shuren HPP is a priority for Mongolia, as reflected in: • – “National Energy Policy” (2015 Parliament Resolution No.63 refers to development of Shuren HPP within 2015-2023) – “Sustainable Development Concepts of Mongolia” (2016 Parliament Resolution No.19)

HISTORIC BACKGROUND In 1964-1965 Soviet “Energosetiproject” design institute undertook studies and concluded that Mongolia has untapped hydropower potential and identified more than 20 potential HPPs, including the proposed Shuren HPP The Leningrad Water Institute selected Shuren dam and developed its feasibility study between 1971-1975
PROJECT LOCATION 5km upstream of confluence of Selenge and Shuren Rivers, 125km from Russia / Mongolia boundary, and 360km from Lake Baikal
OVERVIEW OF KEY TECHNICAL PARAMETERS The Shuren HPP would comprise the following facilities: • Roller-compacted concrete (RCC) dam with fish pass • Spillway system in case of flood • Hydro-electrical power plant • Dam height 65 m, crest length 1200 m • Dam base about 900 m Reservoir volume (full supply level, FSL) of 4.5 Bill m 3 of which • 3.8 Bill m 3 live / useable storage • Reservoir elevation at FSL: 761m above sea level (a.s.l.), minimum operational level (MOL) at 739 m (a.s.l.) • power house; switchyard; access road (225 km) and connecting roads; and a transmission line of approx. 73 km to connect HPP to the grid All technical aspects and parameters will be studied in detail and calculated in the Feasibility Studies
DAM SITE LOCATION COMPARSION Upon identification of locations No.1- 6, a preliminary FS was done based on location 4, viewed as technically most viable It is planned to juxtapose Location 4 with Location 6 at the FS phase through detailed technical and environmental assessment Dam 4: Coordinates: 49°42'29.70"N 104°56'25.72"E Dam height : 60м Installed capacity: 245 MW
REGIONAL ENVIRONMENTAL ASSESSMENT The REGIONAL ENVIRONMENTAL ASSESSMENT will consider additive, cumulative and / or synergetic aspects from SHUREN project and other potential investments (existing and future) in the river basin, e.g.: Direct stressors such as hydropower, irrigation, water abstraction • • Other stressors such as mining, industrial and agricultural pollution, flood management works... Cumulative Impacts from the SHUREN Project include: • Reservoir water quality • Footprint of reservoir, dam, appurtenant structures (land consumption) • Additional / induced impacts of associated infrastructure (access road, transmission lines) • Construction work impacts (incl. pollution pulses due to turbidity) Climatic impacts of HPP •
REGIONAL ENVIRONMENTAL ASSESSMENT Objectives: Scope and Outputs: • Identify environmental opportunities and • Consideration of development plans, policy, legal constraints for development planning at and administrative frameworks the regional level; • Baseline studies, within regional scope • Define and whenever possible quantify • Scenario analysis, projected cumulative impacts environmental and social criteria, against • Impacts mitigation and proposed methodology which project performance can be • Investment planning recommendations assessed; • Environmental management strategy • These criteria would be obligatory to be • Monitoring strategy recommendations considered in the energy development process in addition to economic and • Institutional recommendations technical factors • Detailed ESIA programming
DRAFT TERMS OF REFERENCE FOR ENVIRONMENTAL AND SOCIAL IMPACT ASSESSMENT ENVIRONMENTAL AND SOCIAL IMPACTS ASSESSMENT (ESIA) STRUCTURE On project level, the ESIA will look at the following key issues: (will be based on previous studies) 1. Hydrology / impacts on river flow (rates, volumes, distribution) 2. Dam safety, community health and safety, emergency preparedness and response 3. Environmental impacts 4. Social impacts The geographic scope of the ESIA will extend from the proposed project site(s) downstream along the course of River and include the assessment of impacts, and planning for mitigation measures, for the Russian section of SELENGA RIVER as well as LAKE BAIKAL DELTA.
DRAFT TERMS OF REFERENCE FOR ENVIRONMENTAL AND SOCIAL IMPACT ASSESSMENT ENVIRONMENTAL AND SOCIAL IMPACT ASSESSMENT (will be based on previous studies) • Policy, legal and administrative framework assessment • Baseline assessment • Environmental impact assessment • Tangible cultural heritage • Involuntary resettlement • Indigenous people • Environmental management plan • Community involvement and public consultations
TOR for ESIA: KEY ENVIRONMENTAL ISSUES Impacts on riverine and aquatic ecosystems • Impacts on fish population, species composition, migration • • Habitat formation, conversion, and loss • Impacts on flow regime, volumes, distribution, including tributaries • Impacts on microclimate; influence of weather and climate on severity of anticipated impacts • Impacts on landscapes, natural habitats, natural heritage sites • Erosion, slope stability and induced seismicity in reservoir area and downstream river systems; project in context of regional seismic risks • Influence of climate change on project’s environmental performance
TOR for ESIA: KEY SOCIAL ISSUES
