INTRODUCTION 1. This summary environmental impact assessment (SEIA) is for the Kunming Qingshuihai Water Supply Project (KQWSP), in the People’s Republic of China (PRC), under technical assistance (TA) 4808-PRC from the Asian Development Bank (ADB). The Project is one of a number of initiatives designed to address the increasing demand on water resources to support the rapid growth of Kunming. The Project will make available 111 million cubic meters (m3) of water per annum to be distributed as follows: 104 million m3 for Kunming city, and 7 million m3 for Xundian County, based on projections to 2020. Eastern PRC and Yunnan Province are presented in Maps 1 and 2. 2. This SEIA is based on the environmental impact assessment (EIA) report prepared by the PRC Institute of Water Resources and Hydropower Research, Beijing, and the Yunnan Water Resources and Hydropower Survey, Design and Research Institute (YDRI). It has been augmented by the work of the project preparatory TA team in its project feasibility studies and field inspections. The environmental management plan (EMP) has been developed by the TA team in conjunction with the PRC project proponents, including the Kunming Water Supply Group (KWSG). The EMP includes major mitigation measures described in the EIA and other government documents related to project design and operation. The TA has developed substantial additional EMP provisions based on its own investigations of hydrology, technical designs, health and social impacts, and watershed policy considerations. The resulting SEIA/EMP is wholly owned by the PRC project stakeholders and Kunming municipal government (KMG). 3. The EIA went through rounds of revision based on inputs and suggestions provided by the TA team specialists. The draft EIA report was submitted to the State Environmental Protection Administration (SEPA) for review in February 2007 and supplemented in April 2007 by strategic environmental assessment and environmental protection plan following the EIA requirements. SEPA considered the EIA report to be adequate and authorized the Yunnan Provincial Environmental Protection Bureau (YEPB) for the EIA approval. The Soil Erosion Prevention Plan (SEPP), as required by the Ministry of Water Resources, was reviewed and approved by the Yunnan Provincial Water Resource Department (YWRD) in May 2007. II. DESCRIPTION OF THE PROJECT A. Justification and Rationale for the Project 4. The present and continuing rapid population growth of Kunming is putting enormous stress on city services, especially the provision of clean drinking water. This is especially evident with the proposed establishment of new development areas for Kunming. Past and projected Kunming populations are shown in Table 1. Table 1: Projected Kunming City Population, 2002–2020 Year Population 2002 2,860,000 2020 5,810,000 Source: Feasibility study report. 2 5. Dianchi Lake, Kunming’s past water source, is polluted to an extent that it is currently below Class V in the PRC surface water standards (GB3838-2002).
