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.

Impacts on Water Environment

4.1 Impacts on Water Environmentduring ConstructionPhase

4.1.1 Impact of DomesticSewage

This project is a large-scale project. During construction,the living quarters are located nearby the dam site. The population can reach about 4000 at peak-time during constructionPhase. If averagedomestic sewage dischargeis estimated to be 10OL/person/day, total domesticsewage discharge will be 400 t/d. According to the investigation on similar projects, after the sewage is treated by the settling tank and the septic tank, the content of each pollutant is lower than those in municipal sewage. Usually, COD concentrationis about 50-100 mg/l and BOD5 concentration 30-60 mg/L. Domestic sewage at construction site after being centrally treated can meet the discharge standard. Domestic sewage has little impact on XiangjiangRiver during constructionPhase.

4.1.2 Impact of ProductionSewage

Settlingtanks must be set up to treat the dreg dressing wastewater,Water can be reused after settlement. Dreg dressing wastewater is not discharged after treatment, thus it has little impact on the river. Concrete flushing and curing wastewater will also produce SS pollution. Howeverthe quantity of this kind of wastewater is very small, it has little impact on XiangjiangRiver.

4.2 Impact on HydrologicSituation during OperationPhase

4.2.1 Impact on Water Temperature

When the reservoir reaches the normal impounded level, the total storage capacitywill be 4.7X103m 3 , and the average flow at the dam site is 1670m3 Is. That is to say, the water in the reservoir can be replaced every 3.3 days. The water depth at the dam site is 10m. It is of the typical low-dam run-off-river

-- 11- EnvironmentalAssessment Summary

regulating reservoir. Water temperature structure in the reservoir area of this project is of mixed type. Therefore,the naturalwater temperaturestate will not be affected by the dam construction.

4.2.2 Impact of Project on Hydrology

The reservoir of ZNCP will be controlled together with Dayuandu Navigation Complex. During the flood period, when the reservoir inflow at Hengshan Station is less than or equal to the maximum outflowof PowerPlant, level of reservoirwill remain normal and power will be generated by natural water. When the inflow is higher than the maximum oufflow, gate shall be gradually opened to relieve the flood. When water head in PowerPlant is less than 3m, shutdownshall be carried out. At this time, the navigation complex is fully used to relieve the flood. During the drought period, when the river segment in the downstreamof the dam site is not deep enough for navigation,Dayuandu NavigationComplex will be controlled to compensatethe navigableflow. Navigableflow for Zhuzhou and Xiangtan are 245 m3 /s and 270 m3 /s respectively. After Dayuandu and Zhuzhou navigation complexesare completed,the flow can be adjusted in the drought period. At that time, flow in the segment between Zhuzhou and Xiangtan can reach 342-366 m 31s.

From above, it shows that ZNCP has no impact on downstream hydrology. In special cases, water flow can be controlledby Dayuandu navigation complex. If gate is opened for flood relief, there is no impact on the hydrologyand the safety of dam site.

4.3 Impact on Integral Water Quality in Reservoir Area during Operation Phase

4.3.1 Predictionof Impact on OverallWater Quality Future water quality (year 2015) in the reservoir was predicted through the complete-mixedmodel. As shown in Table 4-1, even in the worst case scenario (dischargewithout treatment in drought period), the water quality still meets the relevant standardsexcept for Total Phosphorus.

4.3.2 Predictionof Oil PollutionImpact in ReservoirArea

Based on the present monitoringresults, we understandthat the oil content in the reservoir area during the drought period is 0.067mg/l, 34% higher than the standard (0.05mg/I). The oil pollution dischargingsource is very few at the reservoirarea for the 96km of Xiangjiang trunk stream. The major oil pollution comes from the discharges from vessels and oil pollution brought about by Xiangjiang Upstream and its branch Mishui River.

1) Impactof Vessel PollutionStandard Dischargeon ReservoirArea

The background value of oil pollution of the water in reservoir area is 0.067mg/l during drought period in 1999. Xiangjiang River is a major river, 90% guarantee flow rate at the dam site during drought period is 320m3/s. Vessel pollution discharging activity is in a random manner. One-dimensionalwater quality model will be used in the prediction,the results of which is provided as below:

In 2005, the external dischargingoil pollutionwill be 12.18t/a,3.65t/a higher than that of 1999. Including the background value, the oil pollution content will be 0.0674mg/l in the reservoirarea.

In 2015, the external dischargingoil pollutionwill be 16.95t/a, 8.42t/a higher than that of 1999. Including the background value, the oil pollution content will be 0.0679mg/lin the reservoirarea.

2) Impact of Vessel Pollution Discharge without Prior Treatment on Reservoir Area

The impact of vessel pollution dischargewithout prior treatment on reservoir area is predicted as below:

Including the background value, the oil pollution content will be 0.1204mg/l in 2005 and 0.1415mg/Iin 2015.

From the above, we understandthat the vessel pollution discharge without prior treatment will cause certain impact on the water in the reservoir area. Therefore, the navigation administrations and the environmental protection units must reinforce control over vessels in order to ensure a standard discharge from all vessels.

4.4 Impact on Water Intake during OperationPhase

4.4.1 Impact on DrinkingWater Intake in HengshanCounty

-- 13 - EnvironmentalAssessment Summary

Organic pollution is the dominant in the assessed area of Xiangjiang River. Accordingto the presentwater quality and main pollutionsources, COD and total phosphorus are determinedfor prediction. A chemical company for pesticide is located in the upstreamof drinkingwater intake of HengshanCounty and is about 7 km away,which is the dominantpollution source in the assessed river segment. The supply of pesticide has exceededdemand in recent years, so this company will not expand. So it is predictedthat sewagedischarge in 2005 and 2015 will be the same as presentcondition.

Taking average value of monitoringresults of S3 section as background value-- 2.16 mg/l of COD and 0.131mg/l of Total P, COD will not exceed the limit at water intake of Hengshancounty in 2015, but total P will exceed in all conditions.

5.1 Impact on Vegetation

5.1 Impact on Vegetationduring ConstructionPhase

Dam construction, construction site arrangement, highway construction, substation construction,explosive magazine setup and stock ground construction etc. will occupy the land and destroy the vegetation. According to the site investigation, there are no precious or rare plants within the reservoir area. Vegetation to be affected includes pine, China fir, tea tree, shrub and weeds. According to the preliminary estimate, 124.3 mu of forestland will be occupied, which includes 5 mu of garden plot, 43.8mu of timber forest, 74.1 mu of economic forest and 1.4 mu of bambooforest. Besides,790 mandarinorange tress, 315 fruit trees, 90 economictrees, 2,782 timbers and 852 bambootrees will be destroyed. After the project is completed, the vegetation destroyed by the construction of substation,dam and buildingscan not be recovered,but the rest of the destroyed vegetation can be recovered.Besides, vegetation covering rate nearby dam site

-- 14 - Environmental Assessment Summary can be increased by strengthening plantation and planting turf so as to further reduce the soil erosion. Therefore, impact of constructionon regional vegetation is temporaryand recoverable.

Building removal and reconstruction will occupy some forestland and shrub. Besides, partial vegetation will be destroyed. 99 mu of forest will be inundated by the reservoir. Since Inundated vegetation mainly includes rice, China fir, economic tree and shrub and there is no rare plant, impact of inundation on vegetation source is temporary. Vegetation covering rate can be increased by plantationand planting.

5.2 Impact on AquaticOrganism

5.2.1 Aquatic Life

According to the monitoringdata for the completed reservoirs in Hunan Province (such as Dongjiang), community structure of water life will change from river phase to lake phase after the dam retains water. In addition, algae composition and original productivitywill change with aging of reservoir.Quantity of plankton and water plant will greatly increase. Furthermore, community structure of benthos will change.

5.2.2 Fish

(1) Impact on Fish Quantity

After the project is put into operation, water flow velocity will be lowered, especially in drought period. This is very beneficial to the sedimentation and accumulation of organic decay and nutrient inorganic salt, which created good external conditionsfor the growth and reproductionof water plants and planktonic algae. Quantity of economic fish will be increased in water body within reservoir area due to the increaseof food organismssuch as planktonicalgae and protozoa etc. After the dam is constructed, a stable water space will be formed in the reservoir area (total length is 96km). Water surface area will be changedfrom 48 km2(before water storage )to 58.9 km2 (after water storage). Besides, volume of water body will be changedfrom 0.25 billion m3 to 0.4734 billion m3. Because the drought period of XiangjiangRiver is long, water surface and water body will form a continuous and stable waters for about 8 months after water storage. This will be beneficial to the growth of water life and the natural reproduction of fish, especially to the net fish-farming. In a word after Zhuzhou Navigation Complex is completed, fishery output will greatly increase. This shows that this project is beneficialto the fishery.

(2) Impact of Fish Population

After the project is put into operation,fish populationstructure will change in the reservoir area. Quantity of fishes which like to live in runningwater will decrease

-- 15 - Environmental Assessment Summary and quantity of fishes which like to live in steady water will increase.At that time, crucian carp. carp and bream will be the dominant fish. Black carp, grass carp, carp and crucian carp are of migration floating fishes. Dam construction will change their living environment,which will be not beneficial to their growth and reproduction. Therefore artificial cultivation and net & box fish-farming methods will be used. At that time, quantity of above-mentionedfour fishes will not decrease but increase greatly.

(3) Impact on Fish Reproduction

Water level difference between upstream and downstream of the dam is about 12m. Thus migrationpassageway will be separated,which is not beneficialto fish reproduction. For the river segment between Zhanghepu and Jiaohegou (total length is 75km),it is suitablefor food fishes to spawn due to its geographiclocation and rive characteristics.A great number of food fishes will come to the above- mentioned river segment to spawn during April to June every year. Original fish source protection programfor Dayuanduproject is that a fish passageway(400m in length) will be constructedto settle the problem of fish migration. However, according to the suggestionsof fishery experts, 9-stage channelizationprogram should be taken for the long-termshipping developmentof Xiangjiang.Therefore if fishes want to go to upstreamspawning place, they have to pass several stages, which will seriously consume their physical power and greatly reduce their reproductivecapability. Above all, the ecology will change for the spawning place after channelization. Therefore the above-mentionedprogram has no practical impact. As viewed from long-termplan, artificial cultivationof fry and periodicalfry introductionwill be more effectiveto protect fish resource in Xiangjiang River and Dongting Lake. This program can solve the problem of fish resource protection and compensation.After having been approved by the world Bank, this program has been successfully executed in Dayuandu Navigation Complex in 1999, 80 million fries have been introducedinto the river at two times till now.According to the fishery resource survey conductedby water product sectors, ever since the beginning till now, the four domestic fishery resources within the reservoir area have increased instead of declining, thus resulting in an increase in the fishing output. In order not to influencethe fishery resource,kind, quantity and location of fry introductioncan be adjusted accordingto actual situation.

5.3 Impact on Public Health

5.3.1 Analysis of Public Health in ConstructionSite

Population density and mobilitywill be both high during constructionof this project. As some servicescan not keep up with the development,infectious diseases may easily appear and spread, such as plague, malaria etc. Therefore sanitation managementshould be strengthenedon the constructionsite. Specific persons should be appointedto be in charge of sanitationand anti-epidemicwork. Drinking water must be sterilized. Health check should be periodically made for the

-- 16- EnvironmentalAssessment Summary workers. If any infectiousdisease is found, the person must be isolated and cured immediately. Sanitation knowledge should be taught to the workers before construction.

5.3.2 Analysis of Public Health in ResettlementArea

Residents resettlementis directly involved with populationflow and goods flow. Following preventive measures should be taken during migrant arrangement so as to reduce the bad impacton health: * Health check must be made for the emigrants before emigration. If any infectiousdisease is found, the person must be given timely treatment. * Drinkingwater source must be carefullyconsidered, and water quality checked by local environmentalprotection department. * A thorough hygienic work must be done in newly-built settlement, such as eradication of rat and mosquito. * Local public health departmentmust check it out regularlyafter resettlement.

5.4 Impact on Soil Erosion

According to site investigation,Classification Standard for Soil Erosion and Water and Soil ConservationPlanning Report are used for assessment. Slopes of occupied farmland, resident quarter and land for communication are between 0C and 5° , and soil erosion is mini-scale.The erosion modulus is less than or.equal to 200t/ km2 year. However,for the occupiedforest land, flood land and grassland, their slopes are between 50 and 15° , and therefore soil erosion is slight-scale.The erosion modulus is 200-10OOtIkm2year. Backgroundvalue of soil erosion is 351.5t/year in the constructionsite of this project,

Constructionsite is taken as predictionrange and constructionphase is taken as prediction time. Prediction of loss of water and soil is based on on-the-spot investigationand the influenceof constructionon the topography,vegetation and slope according to classification Standard for Soil Erosion. The loss of abandoned slag will mainly be measured through the analogue analysis of the observed data. Accordingto above-mentionedanalysis, if measuresfor soil and water conservation are not taken, volume of soil erosion will be increased by 0.7764 million ton. If soil erosion due to waste yard constructionis not considered, volume of soil erosion will be increasedby 3,677 ton.

-- 17 - Environmentaf Assessment Summary

6.1.1.1 PrincipalTangible Material Indices a) Reservoirarea NPL is 40.5 meters,the reservoirinundation will cover some units and 538 villager groups I 90 villages in 14 townships in Zhuzhou, Hengdong, Hengshan and Xiangtan Counties and Liling City. The principal tangible material indices affected by the reservoir inundation are as below: 1,165 displaced persons, 68,737 M2 of housing area; 20,124 mu (1 ha.=15 mu) of farmland, 99.9 mu of forest land, 886 mu of fish ponds; 2.4 km of Grade IV highway,223 drainage culverts and sluices, 246 pump stations, 17.15 km of transmissionlines at 10 kV or more, and 6.2 km of telecommunicationslines. About 95% of the affectedfarmlands are within Zhuzhou Countyand the affected farmland at EI.38.5mor higher accounts for 83% of the total affected farmland. The affected farmland is relatively concentratedwith minor submergencedepth. Most of the affected farmland may be protected fro inundation by taking appropriate measures. About 99.5% of the affected housing are in Zhuzhou County and 62% of the affected housing is of brick-concretestructure. Most of the affected housing may be protectedby taking consolidationmeasures as only the ground floor is affected. b) Dam area

Due to the dam construction,385 persons and 21,000m2 of housing have to be displaced.727.5 mu of farmland,of which 577.2muis paddy field, will be occupied for the dam construction. c) Hengshandock

The total land area of the Hengshandock is 26 mu. 58 persons in 13 households and 4,121m2 of housing have to be displaced. 19mu of orchards and 2 mu of fishpondswill be occupiedfor the wharf construction.

The move- back resettlement option will be employed, and the affected persons will be moved out of the constructionredline and resettled in differentareas.

About 457 persons need productionresettlement. It is plannedto return 200mu of construction site to paddy field, and to adjust 324 mu of paddy field for vegetable plantation. c) Hengshandock

The affected 58 persons in 13 householdswill be moved backwardto resettle in the area with the elevationabove the Hengshan-Xuanzhouhighway. 6.1.1.3 ResettlementCompensatory Investment

Calculated based on the 1999 price level, the total resettlement compensatory investmentof the Project is 304.4138million yuan, of which:

a) Reservoir area: Basedon the NPL 40.5m scheme,the static investmentfor the reservoir inundationhandling is 271.6599million yuan.

b) Dam area: The static investmentis 30.6852 million yuan (including 10 million yuan for the Kongzhouislet). c) Hengshan dock: The static investmentis 2.0687 million yuan.

6.1.1.4 Impact of Land Acquisitionand Resettlementon Social Environment

(1) FavorableImpact * To make full use of the superiority in water resource and promote industrial structure adjustment. * To enhance the capabilitiesto cope with natural disasters. * To improve the quality of life for relocatees. * To raise the productiveforce of land by properly developingland resource in resettlementarea.

(2) Adverse Impact * Average farmland area per person is small and back-upfarmland resource is

-- 19 - EnvironmentalAssessment Summary

limited. Reservoir inundation, resettlementand special facilities construction will occupy some land. Therefore, contradictionbetween farmland resource and populationsize becomes more prominent. * During resettlement,village migration,house constructionand special facilities reconstructionwill occupy some land and destroy original vegetation. Surface soil will be peeled and original landform will be changed, which cause soil erosion to some degrees. * Resettlementproblem is very sensitive.Some people have to give up original stable living conditionsand rebuildtheir home village. If resettlementproblem is improperlysolved, it will bring some unstablefactors to the society.

6.1.2 Impact on RegionalEconomic Development

Construction of Zhuzhou Navigation Complex Project will speed up implementationof the strategy,namely giving priority to One point and One Line economic development. After the navigation complex is completed, irrigation conditions will be improvedfor 0.128 million mu of farmland on the both bank of reservoir.Besides, fishery can be developed.Thereby, construction of this project will provide excellent conditions for economic development in reservoir area. This project is an importantpart of XiangjiangRiver Basin plan. It is beneficial to full utilizationof water resource in XiangjiangRiver. This project will further raise the comprehensiveutilization rate of water resourcein XiangjiangRiver.

6.1.3 Impact on CulturalRelic and Historic Sites

According to field surveying and investigation,the historical sites of Kangwang Templeand Jianning Countyand ZhutingjunTown are far awayfrom the banks of Xiangjiang.The tomb of the martyre Mao Zejian is 300 meters away from the bank at the end of the reservoir.Konglin temple is about 1 kilometerfrom the dam of the Complex. The reservoirtakes the shape of a channel.When it is filled with water, the water will be confined within the river course. As the historical sites are far away from the banks, thus the constructionwill have very little impact on them.

6;2 Impact on AtmosphericEnvironment The main air pollution sources during the construction phase are the mixing stations, truck (carrying earth) haulage and loading and dumping sites. The assessment factor is TSP at this period and the analysis is done by the comparisonmethod. The concrete used for the constructionof a dam is chiefly preparedat the mixing stations.So the dust productionis concentratedaround the mixing station, normallywithin a radius of 200m areas.

6.3 Impact on Acoustic Environment

-- 20 - EnvironmentatAssessment Summary

6.3.1 Noise Impact duringConstruction Phase

The noise level reduces to 75dB at a location 30m away from the source. The bigger the distance, the lower the noise level. It is 60dB when the distance reaches 120m and 55dB when the distance goes beyond 200m. Thus the noise level at locations 30m away from the operatingmachines conforms to the daytime standard of "the threshold values of noise at building & construction site" (GB12523-90).At locations 200m away it satisfies the night standard. Since the project locates in the countrysideand there are few noise-sensitivepoints in the region, the noise level is acceptable as long as due attention is paid to overall layout and working schedule.

6.3.2 Noise Impact during OperationPhase

Upon the completion of the Dam, the highway on the crest will be put into use which will certainly bring about traffic noises to some extent, which will be measured according to Specificationof Highway Project Environmental Impact Assessment by the Ministry of Transport. According to the above prediction pattern, the calculatedresults of the noise impact caused by the traffic on the both side of the highwayon top of the Dam are listed as below:

Distance (m) 15 30 50 100 150 Predicted Noise 60.9 56.1 53.2 50.8 48.9 Value (dB(A))

From the above, it shows that in daytime, the noise value 50m away from the highwayon top of the Dam is in compliance,with Class I Standard in GB3096-93 Urban Area Noise Environment Standard. Therefore the traffic noise arising during the operationphase has little impact on the outer environment. 7. AlternativesAnalysis

7.1 Dam Site Alternatives

In the feasibilitystudy of this project,the recommendeddam site has been moved down 22km from Gantianto Kongzhou.

As the distance between Gantian and Kongzhou is only 22 km, so they are located in the same environmental region. Therefore their land and aquatic ecology, vegetation coverage,water losses and soil erosion etc are very similar. There is no distinct difference in environmental compatibility. Therefore, considerationis mainly given to geology,economic benefits and social benefits in the selection of dam site. Through the alternative analysis, it is found that Kongzhoudam site is closer to Zhuzhou City and the channeledwaterway is 22 km longer than Gantiandam site. In addition, installedcapacity of generating sets in Kongzhou is higher than that in Gantian, which will bring about greater

-- 21 - EnvironmentalAssessment Summary economic efficiency. Besides, emigrated population number and inundated farmland area will be smaller and the geologicalin Kongzhouis beKterthan that in Gantian. Either from the perspective of economy or from the perspective of environmentalprotection, Kongzhou dam site is better than Gantian dam site.

7.2 Alternativesof Carrying out he Projectand Not Carryingout the Project

The two alternatives are reviewed from the aspects of society, economy and environmentalprotection. It shows that Alternative I (carryingout the Project) is a better choice than Alternative II (not carrying out the Project)from all aspects with respect to economy, society and environmental protection. Therefore, this Assessment recommendsthe Alternative I known as "carrying out the Zhuzhou NavigationComplex Project". 8. EnvironmentalImpact Analysis of Zhuzhou-Xiangtan SectionWaterway Dredging& ExpansionProject

8.1 Outline of Project

This project is to rectify, expand and newly build the channel (waterway) on the basis of the completed kiloton-class channel (width is 60m). 270,350 m3 of waterway will be dredged for the waterway between Zhuzhou and Xiangtan. 44700 m3 of stone dam will be constructed.4000m 3 of rock will be blasted and 5100 m3 of bank revetmentwill be constructed.Total investmentin this project is 14.58 million RMB.

8.2 Present AquaticEnvironment for XiangjiangRiver Zhuzhou-Xiangtan

8.2.1 Water Quality in ZhuzhouSegment

Concentrationof N-NH3, petroleum and mercury are above standard values at Xiawan section either in drought period or in normal period. Maximum surpassing time of N-NH3 is 10( in normal period), of petroleumis 1.5 (in drought period) and Hg is about 9(in drought period). Only petroleumconcentration is above standard value at Baishi section and its maximum surpassingtime is 1. Pollutionat Xiawan section is more serious than that at Baishi section because Xiawan section is polluted by the wastewaterdischarged from Xiawan Port.

8.2.2 Water Quality in Xiangtan Segment

According to the historical monitoring information, water in this segment is polluted to some degree either in drought period or in normal period. Main pollution factors such as petroleum, N-NH3, Hg and Cd etc are above the standard values. Their surpassingrates range 25-75%.

8.3.3 Bottom Sludge in RiverSegment betweenZhuzhou and Xiangtan

-- 22 - Environmental Assessment Summary

The bottom sludge is monitoredin Dec. 1999,sampled, naturallydried and oven- dried for analysis: the control specifications of contaminants for Agricultural sludge (GB4284-84)is taken as the standardfor the assessment.Compared with the standardvalues, such items as Hg, Cd, As, Pb, Zn in the bottom sludge at the Xiawang section are above the assessmentstandards to some degree. However, the heavy metals in other sections meet the standards.

8.3 Environmental Impact Analysis of Waterway Dredging & Expansion Project

8.3.1 Impact on Commonwater Body

Channel dredging and excavationwill disturb the sludge deposits in water body, which will make water temporarilymuddy. Constructionboats and machinerywill also discharge oils and other pollutants into water body during work and maintenance. Domestic rubbish domestic sewage and dung for constructorswill be discharged into water. Thereby,if it is not properlymanaged, water body will be polluted to some degree. However,because the construction site is dispersed in the river channel with its length of 37km and work is not concentrated at a fixed time, it will not greatlyaffect the water quality of water body,on the other hand, the constructors are dispersed, thus domestic sewage dischargewill have very few impact on water body. Furthermore,the impact is temporaryand recoverable.

8.3.2 Impact on Water Quality in SanitaryZone for DrinkingWater Source

There are eight shoals in the river segment from Zhuzhou to Xiangtan. Seven water intakesfor waterworksare involvedwithin the assessmentarea. Except for water-intakes for Zhuzhou First Waterworks and Zhuzhou Second Waterworks are located in the upstreamof TongLuoShoal, other five water intakesare located within the range of this WaterwayDredging Project.According to the investigation, water quality at each water intake is polluted by petroleum, N-NH3 and COD to some degree. Thereby, importancemust be put on water pollution prevention in sanitary zone for drinking water during the constructionof Waterway Dredging & Extension Project. For that reason, effective measures must be taken to protect the drinking water source. Water source monitoring work must be well done during construction. If any pollution to water quality is found, suitable measures must be taken immediately.

8.3.3 Impact of secondary Pollution of Heavy Metals in Boftom Sludge on Water Quality of Water Body

According to the present situation of bottom sludge pollution in the assessment area of this project, no surpassing heavy metal content is found in the bottom sludge except for Xiawan section. As it is surrounded by alkaline water, the heavy metal content is relativelystable in the bottom sludge with a low solubility,

-- 23 - EnvironmentalAssessment Summary only a very little amount of the heavy metal content was left over in the bottom sludge and had certain impact on the water quality by causing suspending substance. As the aqueous phase of this section shows pH>7, the water is categorized as micro-alkli body. The heavy metals containedin the bottom sludge is in a stable condition, The possibilityof heavy metal dissolution due to bottom sludge re-suspension is very small. Although the heavy metals content in the bottom sludge of Xiawan Section is excessive, the dredging project does not include Xiawan Section, therefore, little heavy metals containedin bottom sludge will arise, thus causing no secondarysuspensions and affectingthe water quality. 9. Environmental Impact Analysis of Hengshan Kilo- tonnage Dock Project

9.1 Outline of Project

Hengshan port is located on Xiangjiang River reach between Hengdong County and Hengshan County, and waterway and inland transportation are well developed. Transport industry is featured by local mineral transportation, especially such nonmetallic mineral as plaster,porcelain clay, albite, potash spar etc. In considerationof the navigablecapacity of Xiangjiang River,the throughput is designed to be 18 X 104 t as per universaldock. One kiloton-classberth will be built. Dock type is of generalcargo dock. The highestwater line is designed to be 52.26m (for 20-year encounteredflood, the same elevationas Huanghai,similarly hereinafter) and the lowest 38.80m (the dead water level of Zhuzhou Navigation Complex). Total investmentfor this program is 16.85 million RMB.

9.2 Survey of Present Regional Environment at Hengshan Kilo-tonnage Dock site

This kilo-tonnage dock will be on the lower reach, around 8km away from Dayuandu dam and the port zone on the lower reach, around 550m away from water intake for Hengshan Waterworks. To confirm the existing water quality, a monitoring cross-section was selected at upstream,around 100m away from the water intake. Ten monitoring factors such as PH, SS, DO and petroleum are included in the monitoringfrom Dec. 4 to 6,1999 (totally three days). The result shows, except for petroleumand total phosphorus,pollutants do not exceed limits. Petroleum on its peak is 4 times exceeding limits, with exceeding rate of 33%, which means this river reach has been polluted by petroleum contaminant that mainly come from transport ships. Thus, petroleum contaminant is one of the most selective control factors for pollution prevention. Total phosphorus on its peak is 0.87 times exceeding limits, with exceedingrate of 66%.

9.3 Impact Analysis of HengshanDock Construction

9.3.1 Impact on Flood Discharge

-- 24 - Environmental Assessment Summary

The proposedconstruction place for the Dock faces a 600m wide XiangjiangRiver reach. Under the highest historicalwater level, flood-relief section area is about 7500 m2. The head of the Dock extends about 28m from the boundary line of river bank, with water-tight area 210 m2 , occupied only 2.8% of total flood-relief area, comparingwith Xiangjiang River Large Bridge on the lower reach, it has a piers water-tight area 600 m2 . Since completion of the Bridge, Hengshan reach of Xiangjiang River has stood up flood tests for years. In contrast, Hengshan Dock construction program has much smaller water-tightarea. To this understanding,it is predicted that construction of this project will not markedly impact flood discharge.

9.3 2 Impact of Oily Sewageon Water Body

Usually, oily sewage from berthed vessels is not allowed to be freely discharged into water body except that it has been treated and up to the effluent standard. The effluent concentrationof oily sewage after treatment is 10 mg/L. If sewage dischargeis counted as 2t per day, dischargeintensity of petroleum pollutantswill be only 20g/d, impactingthe water bodyvery little. Thus, oily sewage impacts very little on the quality of drinkingwater for HengshanCounty. 10. PublicConsultation

According to the World Bank's guideline, two stage public consultation was carried out; namely a) shortly after environmentalscreening and before the terms of referencefor the EA are finalized(First Public Consultation),and b) once a draft EA report is prepared(Second Public Consultation).

10.2 Second Public Consultation a. Survey date: Upon the completion of EIA draft in July of 2000, the preliminary result was released to the public in reservoir area for opinions; b. Survey location: As the most affected people living in reservoir area, the major survey locations including Panshi Town, Sanmen Town, Zhouping Village and Gantian Town in Zhuzhou County;

C. Survey method: Public consultation meetings being held four times with respect to ZNCP; d. Survey object: The to-be-affected public of this project (local villagers) being asked to provide their opinions and suggestions on the environmental protection in this project, 30 people from Zhouping Village (meeting held on July 18, 2000), 28 people from Sanmen Town (meeting held on July 20, 2000), 22 people from Panshi Town (meeting held on July 21, 2000), 20 people from Gantian Town (meeting held on July 22, 2000) e. Survey results: The attendees of the four meetings totaling 100, most of which in favor of this project and also giving out a variety of opinions and suggestions.

Positive opinions are based on the following reasons: * The project will be beneficial to promoting the regional economic development, expediting the urbanization proceedings and speeding up the development of

-- 26 - Environmental Assessment Summary

tertiary industry as well as the adjustment of industrialstructures in reservoir area.

* This project constructionwill upgrade Xiangjiang River navigation waterway. Besides and be beneficial to the development of waterway transport. At the same time, dam-crest highwaywill connect 107 National Highwayon the east bank with Beijing-ZhuhaiExpressway on the west bank and bring convenience for highwaytransport.

Negativeopinions are based on the following reasons: * In their opinions, after the dam is constructed,water flow velocity will slow down within the reservoir area and the natural degradationcapability will also be weakened,which will be adverse to dilution and diffusion of the pollutants. Besides, they showed great concern for the water quality in reservoir area, especially the water quality of drinkingwater source in reservoir area (such as drinking water intake for Hengshancounty).

Public suggestionsand requirements: * The project is expected to be constructed,operated and profitable as soon as possible. * In view of cultivatable land is rare in the construction area, mitigation measures must be taken to reduce inundationon farmland and the number of the resettledas much as possible. * Environmentalprotection shall be sufficiently implementedduring the course of constructionto minimizeecocide and environmentalpollution. * This project may cause the reduction of fishes in Xiangjiang River, compensation given according to the policy or remedies to be taken are suggested. * Along with constructionof the project, land acquisitionshall be well settled by unified planning with due considerationfor all concerned. Full the amount of compensation shall be given to the resettled according to the policy so that farmers can survivetheir land acquisition. * Dam-cresthighway is an importantlink betweeneastern and western regional transport, vehicle flow is great. Since the current design for (9m wide with two-lane) is too narrow and can not meet the demands of transport in rapid development. The Government an the Owner are suggested to widen the dam-crest highwayup to four-lane.

Prior to the finial completionof the EnvironmentalImpact Statement, the above public opinions have been carefully reviewedand referredto in the major chapters and environmentalprotection programs.

11. EnvironmentManagement Plan

11.1 EnvironmentalProtection Measuresfor Zhuzhou Navigation Complex

-- 27 - EnvironmentalAssessment Summary

Project

11.1.1 Design Phase

1) Flood Preventionin the ReservoirArea

Select correctly the site of the dam, the type of the dam, the style of flood discharge, the width of overflow edge and the normal storage level so as to reduce the loss of inundationand avoid influencingflood prevention in reservoir area. In order to reduce the inundated area and not to influence the flood protection in the reservoir area, general layoutand normal storage level has been carefully studied and demonstratedduring project design. Overflow leading edge has been widened. Height of bed sill for overflow gate is lowered as far as possible (near original riverbedelevation). Therefore, a low and open gate dam is formed. During flood discharge, Flow State of flood will approachthe Flow State of natural water. Normal storage level of the reservoiris 40.5m. Water level in the upstreamof the dam will be limitedwithin the flood banks.

2) Embankment Protection

During design phase, topographical survey is required for the embankment protection in orderto confirmthe locationsof embankmentwith potentialhazard of permeation, which shall be treated accordingly. As the water level rises, the water surface becomes wider and the embankmentis immersed in water longer and is exposed to greater influenceof the wavesand water erosion. In the design, measures like laying stones, building slopes and growing grass are taken to harden some soft and cragged banks.

3) Water DischargeFacilities

In the design, the inundatedwater dischargesluice, flood dischargechannels and electrical drainage facilities will be renovatedand improved before water is filled into the reservoir.

4) Field Protection:

Before water is filled into the reservoir,flood discharge channels will be built or renovated, new electrical pumping station built and various plans improved. The follow-up supportivework will be seen to.

5) Ecological Protection

Efforts will be strengthenedin afforestationin the reservoir area to increase the area of vegetation coverage and preventthe loss of water and soil and promote ecological agriculture.

2) PreventiveMeasures for Wastewaterin ConstructionSite

* Living quarters for constructorsmust be dispersedso as to reduce the central wastewater discharge. * The site living sewage will be processed at the septic tanks first and then discharged to embeddedsewage processorsfor final emission in compliance with the standards. The concrete residue-flushingwater from the concrete system will be settled at the settlementtanks for recycling, none of which be discharged out. * Machine repairing yard must be located at the downstream of construction site. * Oil-water separator should be installed in the machine-repairingworkshop. Oily wastewatershall be dischargedafter treatment.

3) PreventiveMeasures for Noise Control in ConstructionPhase.

* Noise produced by constructionmachinery. Noise mainly has an impact on the constructors. Work schedule should be properly arranged for the constructorsduring construction.High noise-contacttime should be shortened as far possible. Besides,living quartersfor constructorsmust be far away from high noise work-site as far as possible. * Construction machinery must be rationally selected. Low noise equipment should be used as far as possible. Preventive maintenanceshould be often made for the construction machinery during construction so as to avoid the noise increase due to equipment performance drop. Noise insulation and

-- 29 - EnvironmentalAssessment Summary

elimination measures should be taken for the generators. Besides, the generatorsmust be far awayfrom dense-populationarea. * For the construction machinery whose noise level is above 9OdB(A), for example, pilling machine,pneumatic hammer and rock drill etc, work schedule should be properlyarranged, besides, night constructionshould be reducedas far as possible. * Blast should be performed during daytime. And no blasting is operated from 18:00to 7:00 (next morning).

4) Processingmeasures for residue

* Site living garbageshall be jointly transportedto garbageprocessing station at Zhuzhou for disposal. * Constructionwaste soil and stones can be transportedto and stockpiledat the nearest residue-disposalsite. 3 specialwaste soil stockpilingsites with a total area of 477,900 m2 will be constructedat the both banks of the Dam site.

5) Farm land protectionmeasures

ZNCP will inundate farmland of 20,142 mu at the reservoir area, 17,339 mu of which could be protectedby taking the following proper protection measures:

- To construct drainage channel:the ponding water in farm fields will be drained to the river at the Dam's downstreamthrough drainage channel; * To raise the farm land: farm fields will be raised to over 41.0m; (practical for the areas with low water level discrepancybetween outer and inner banks or the areas with great permeability) * To drain out ponding water: Ponding water inside the farm fields will be forcedly drained out with pumps; (practical for areas with high water level discrepancy between outer and inner banks or the areas with low permeability).
