INTRODUCTION 1. This report summarizes the results of the environmental impact assessment (EIA) of the Guangxi Wuzhou Urban Development Project. It is prepared in accordance with the requirements of the Environment Policy (2002) and Environmental Assessment Guidelines (2003) of the Asian Development Bank (ADB) on the basis of prepared domestic EIA reports that meet the requirements of the People’s Republic of China (PRC) EIA Law, 2003,1 and associated regulations. The domestic EIA reports include three environmental impact statements and two tabular environmental impact assessment reports (TEIARs) as follows: (i) TEIAR for the Pingminchong geohazard resettlement and prevention; (ii) TEIAR for the Zaochong resettlement site; and (iii) environmental impact statements for the Hongling road network.2 2. Qualified local institutes prepared the domestic EIA reports using methodologies and standards consistent with relevant guidelines established by the PRC State Environmental Protection Administration (SEPA). The Guangxi Environmental Protection Bureau (EPB) approved the environmental impact statements for the Hongling road network; and the Wuzhou EPB (WEPB) approved the TEIARs for the Pingminchong geohazard resettlement and prevention and Zaochong resettlement site. The project preparatory technical assistance (PPTA) consultants assisted in finalizing the EIA reports, particularly in preparing the environmental management plans (EMPs). 3. Soil erosion prevention plans were prepared for the bridge, road networks, Pingminchong rehabilitation site, and Zaochong resettlement site in accordance with the PRC Law on Soil Erosion Prevention Control, 1991. The Wuzhou Water Resources Bureau reviewed and approved the soil erosion prevention plans. 4. As part of the preparation leading to the PPTA, ADB commissioned a geohazard situation analysis to better understand the issues and needs in Wuzhou.3 Domestic feasibility studies and resettlement plans were prepared under the guidance of the PPTA consultants. The findings of these studies were incorporated in the summary environmental impact assessment (SEIA). 5. A detailed description of the EMP is presented in Appendix 1. The EMP entails a summary of the anticipated impacts and mitigation measures, environmental monitoring program, public consultation program, responsibilities for implementation and supervision, institutional strengthening and training plan, reporting and supervision, work plan, cost estimates for environmental management, and mechanism for feedback and adjustment. 1 Ministry of Environmental Protection. 2003.

Urban development in Wuzhou is severely constrained by its geological and geographic conditions. The city is located in a mountainous region; two rivers divide it into three parts. The city proper is on the north bank of Xunjiang River,4 which is further divided by Guijiang River into (i) the old urban center on the east, and (ii) a fast-growing urban center on the west. The south bank of Xunjiang River is undeveloped.
