EXECUTIVE SUMMARY A. Introduction 1. The Dengzhou City Government (DCG) of Henan Province, People’s Republic of China (PRC) has requested the Asian Development Bank (ADB) to provide investment and technical assistance support for the Henan Dengzhou Integrated River Restoration and Ecological Protection (the project). Based on ADB’s Safeguard Policy Statement (SPS, 2009) the project is required the preparation of a project initial environmental examination (IEE). 2. This IEE has been prepared in accordance with ADB’s SPS requirements and PRC environmental laws, regulations and standards. It is based on information and data from: (i) domestic tabulated EIAs (TEIAs) prepared by the Henan Zhengde Environmental Technology Ltd; (ii) feasibility study reports (FSRs) prepared by the Northern China Municipal Engineering Design and Research Institute; (iii) environmental and social assessments conducted between November 2018 and March 2019 by the consultants for the project transaction technical assistance (TrTA), in cooperation with the FSR institute, DEIA institute, and DCG. B. The Project 3. The project area encompasses urban and rural regions of Dengzhou City, a prefecture- level city in southwestern Henan Province. The project aims to improve the quality of life for residents in the Yangtze River Economic Belt. The project will have the following outcome: water security and environmental sustainability in Dengzhou City improved. The key components of the project comprise wastewater management, construction of water supply systems to rural areas, solid waste management in a rural township (Rangdong), natural drainage regulation in a new development district (Tuanbei New District), control of non-point source pollution, wetland development along Tuan River (a tributary of the Han River), and institutional capacity strengthening in integrated water resources management (IWRM) for relevant agencies of Dengzou City. The project will have three outputs, as follows. 4. Output 1. Urban and rural water infrastructure in Dengzhou City improved. This output will include: (i) wastewater management including (a) installation of distributed wastewater treatment facilities in rural areas, (b) construction of a centralized wastewater treatment plant in urban area, and (c) construction of wastewater collection networks; (ii) rural water supply system including (a) construction of water intake and treatment facilities, (b) installation of distribution network, and (c) installation of advance monitoring and evaluation system; (iii) solid waste management in rural towns including (a) solid waste separation and recycling facilities, and (b) establishment of solid waste collection and transport facilities; and (iv) flood risk management including construction of (a) ecological dike at critical locations, and (b) stormwater drainage 5. Output 2. Ecological zones in Tuan River restored. This output will implement (i) river corridor improvement including (a) removal of wastes from Tuan River by using ecological dredging method, (b) construction of Tuanbei cultural park, and (c) greening and gardening along the river banks in city area; (ii) soil and water conservation including (a) river bank protection with eco-friendly measures and (b) plantation of bio-shield and construction of runoff interceptors to control nutrients and top-soil leaching from the farm lands, and (c) afforestation on hill slopes in the watershed of Danjiangkou Reservoir; and (iii) wetland restoration including (a) construction of artificial wetlands, (b) restoration of small creeks to enhance the natural drainage system. 6. Output 3: Water resources management capacity enhanced. This output will develop (i) Environmental research and education center for Tuan River watershed including (a) construction of building and research laboratories, (b) installation of research equipment, 2 and (c) cooperation with local
