General 1.1 Motivation Xiangjiang River, originating from HaiyangshanMountain of Linchuan County, Guangxi Zhuang Autonomous Region, is the biggest river within Hunan Province and a first-grade branch of Yangtze River. It runs through Hunan Province from south to north and empties into YangtzeRiver at Chenglingjiof Yueyang city, with a total length of 969 km and a drainage area of 94,660 km2. Hunan's major industrial cities such as Yueyang, Changsha,Xiangtan, Zhuzhou and Hengyang are all situated on its riverside. 70% of the large & medium-scale enterprises thereof are sited along Xiangjiang River, therefore, Xiangjiang River is regarded as the economic corridor of Hunan Province. In 1999, Hunan Provincial Party Committee and Government set forward a strategic target aiming at acceleratingthe priority regional economy development, known as One Point and One Line, and speeding up the economic integration program of three cities, respectivelyknown as Changsha,Zhuzhou and Xiangtan. Zhuzhou Navigation & Power Complex Project is now officially listed in the Government'sagenda. MOC and Hunan Province have included XiangjiangRiver Rolling Development Project - Zhuzhou Navigation & Power Complex Construction into national and provincial early-stageschedule of The Tenth Five- Year Plan. Hunan Provincial Communications Department (HPCD) entrusted Hunan CommunicationsPlanning & Designing Instituteto prepare the Feasibility Study and the Project Proposal in March 1999. Upon the completion of which, HPCD further entrusted Hunan Environmental Protection Science Institute (HEPSI) to prepare Environmental Impact Report of Xiangjiang River Zhuzhou Navigation & Power Complex; Upon the receipt of the assignment, HEPSI promptly established an EnvironmentSubject Assessment Division, which after carefully analyzing the relevant project information, conducted a site survey at Zhuzhou Complex dam & reservoir area, monitored the present regional environment and collected a series of routine monitoringdata regarding pollution source and water quality at the site. On which basis, the Environmental Impact Report of Xiangjiang River Zhuzhou Navigation& Power Complexwas prepared. Besides the self-raised funds, Zhuzhou Complex Project intends to apply to the World Bank for an $100 million loan. In accordance with the Assessments Categorizing Standards provided in Notification on Reinforcing Environmental Impacts Assessment Administration over International Financial Organizations Funded Construction Projects reference No. [1993] 324 issued by National EnvironmentalMonitoring Division (NEMD), the environmentalAssessment of the Project was categorizedas Type A. -- 2- Environmental Assessment Summary 1.2 Assessment Objective The preparation of EnvironmentalAssessment is designed to confirm the scale and extent of the impacts on the surroundingenvironments in order to work out practical measures to avoid the adverse impacts and provide technical supports for engineering designs and environmentaladministration. 1.3 Assessment Basis The policies and regulations governing the environmentassessments are listed as below: * Environmental ProtectionLaw of People's Republic of China, Water Pollution Prevention Law, Atmosphere Pollution Prevention Law, Noise Pollution Prevention Law,Water & Soil ConservationLaw; * Construction Projects EnvironmentalProtection Control Rules State Council Decree ReferenceNo.: 253; * Notificationon ReinforcingEnvironmental Impacts Assessment Administration over International Financial Organizations Funded Construction Projects NEMD ReferenceNo. [1993] 324; * Hunan Xiangjiang River Drainage Area Water Pollution Prevention Regulations; * Xiangjiang River Waterway Development Zhuzhou Navigation & Power Complex; - Project FeasibilityStudy; HunanCommunication Planning Institute; and * The World Bank, OP4.01 EnvironmentalAssessment. 1.4 Sphere of Assessment This project is composedof two phases: constructionphase and operationphase. The impacted area of the constructionphase is the KongzhouDam site, while that of operation phase covers the entire 96km reservoirbackwater area. 1.5 Assessment Standards * The executive standards reviewed and approved by Hunan Environmental Protection Bureau for environmentassessment in this project are provided as below: * Water environment assessmentstandard: In accordancewith Water Quality Type 2, 3 and 4 Standards specified in GHZB1-1999 Surface Water environmentQuality Standard. * Atmospheric Environment Quality Standard: Type 2 Standard specified in GB3095-1996 Atmospheric EnvironmentQuality Standard is to be observed for all assessmentareas. * Acoustic Environment Quality Standard: In construction phase, GB12523- 93 Construction Site Noise Limit Value is to be observed; In operation -- 3 - Environmental Assessment Summary phase, Type 4 Standard specified in GB3096-93 Urban Noise Limit Value is to be observed for highways at the two sides of the Dam; And Type 1 Standard specified in GB3096-93 is to be observed for present situation assessment. Sewage Discharge Limits: Limit Grade 1 specified in General Sewage Discharge Limits is to be observedfor sewage discharged to water areas of Type 2 & 3 specified in GHZB1-1999. Limit Grade 2 specified in General Sewage Discharge Limits is to be observed for sewage discharged to water areas of Type 4 specifiedin GB8978-1996. 1.6 Objectives of EnvironmentalProtection * Protect the source of drinking water in the 96km reservoir area. According to the functional plan of regionalwater areas, livingwater sourcesin the reservoir area mainly includetwo places: the intake of HengshanCounty Water Supply Factory and the intake of Hengdong County Shiwan Town Water Supply Factory. * To protect the ecological environment, including the water organisms, vegetation in the assessment area and Kongling'an Tourist Attraction Site, 1km downstreamfrom the Dam. * To protect the residentsin the vicinity of the Dam from noise and dust pollution. 1.7 AssessmentAssignments The assessmentis conductedby Hunan EnvironmentalProtection Institute (HEPI) assisted by Hengyang EnvironmentalProtection Institute (HYEPI) and Zhuzhou Environmental Protection Monitoring Station (ZEPMS). HEPI is responsible for the preparation of the Outline& the Reportand partial site work while ZEPMS and HYEPI are responsible for the site monitoring and pollution sources data- collecting. HEPI has been engaging in the environmental assessment and management ever since the early 1980's. It has been categorized as National First Grade Unit. Over 50% of the major or secondaryprojects' assessments were conducted by HEPI. 2. Outline of Project 2.1 Overview Zhuzhou Navigation Complex is located at Kongzhou,within Zhuzhou County in the downstream of Xiangjiang River. This project is categorized as Class IlIl project, and the major buildings are designed accordingto the standardsfor Class ll. The designed flood repetitionperiod is 50 years and the check flood repetition period is 500 years. The site of KongzhouDam is recommendedas the dam site for ZNCP, which is 83 km from HengshanCounty, 24 km from Zhuzhou City, and 96 km from the completed dam site of Dayuandu Navigation Complex. It is located between HengshanHydrologic Station and Zhuzhou HydrologicStation. -- 4 - Environmental Assessment Summary Zhuzhou Navigation Complex Project (ZNCP) is an integrated project, which combines navigation, power generation, communications and irrigation. Main buildings in this project consist of sluice gate, power plant house, navigation lock and highway bridge. The total constructionphase is 5 years. It will take 32 months to complete the navigation lock and 36 monthsto put the first generatingset into operation. The total investmentis 1.814 billion RMB, which includes 1.753 billion RMB for the Navigation Complex Project and 0.017 billion RMB for Hengshan Kilo-tonnage Dock Project is and 0.014 billion RMB for Waterway Dredging Projects. 0.1 billion USD will be loanedfrom the World Bank and the balance will be obtained from the Ministry of Communicationsand Hunan Province (i.e, subsidies and self-raisedfund). According to the plane layout of the dam, power plant is placed on the left branch, with a 12-hole sluice gate, and a permanentnavigation lock on the right branch, with a 14-holesluice gate. The height of dam is 50.8 m and crest length 1068.5 m. The normal water level of the reservoir of Zhuzhou NavigationComplex is 40.5m and the relative capacity 0.4743 billion m3.
