EXECUTIVE SUMMARY 1.1 Introduction 1. Purpose of the project. The Ministry of Transportation (MOT) of the People’s Republic of China (PRC) is encouraging investment in inland waterways to promote the movement of goods, which makes use of the large inland waterway system, is suitable for the bulk transport of non-perishable goods, and is environmentally-friendly compared with investment in road and rail. The Hunan Province Department of Transport (HPDOT) has been involved in the planning and execution of a cascade of nine multi-purpose barrages on the Xiangjiang River, a tributary of the Yangtze1, over the last two decades. The main objectives of the cascade are to raise the navigation standard on the river to Class III and provide hydropower. The Hunan Xiangjiang Inland Waterways Transport Project (herein referred to as the Project) is the second to last of the complexes to be implemented and has been identified for financial assistance from the Asian Development Bank (ADB). 2. Scope of work. The preparation of the EIA has involved: the collection of information related to the environmental conditions in the study area; the preparation and critical review of the EIA methodology followed by the commissioning of special studies to evaluate the water environment, fisheries, terrestrial ecology, soil and water conservation, and physical cultural resources; the assessment of potential location specific environmental impacts; the development of preventive / mitigation measures for significant impacts; the evaluation of alternative locations for the Complex and alternative technologies; economic assessment of the environmental benefits and costs; preparation of the Environmental Management and Monitoring Plans; and extensive public consultations. 1.2 Critical Facts 1.2.1 Legal and Administrative Framework a. Legal Framework 3. The PRC’s environment legal framework is similar to international practices and is structured as shown in Table 1.1 below.

EIA Requirements 4. The Project will be subject to the environmental requirements of both the PRC and those of the ADB. These requirements are as follows. 5. EIA requirements of ADB. The ADB EIA requirements are set out in Safeguard Policy Statement (2009). This Project has been screened for expected environmental impacts and categorized as Category A: projects with potential for significant adverse environmental impacts ─an environmental impact assessment is required to address significant impacts. This EIA reports has been prepared based on Appendix 1 of the Safeguard Policy Statement (2009). 6. EIA Requirements of the PRC. The EIA requirements of the PRC are regulated by the Law on the Evaluation of Environmental Effects. The EIA requirements are further elaborated in a series of technical guidelines and standards which cover general principles, a range of topic areas (surface water, air, noise, etc) and issues related to construction in general and the development of hydropower and water conservancy projects.
