17
long shall be arranged at the left bank to connect with each construction site. The totallength of construction road is 5.00Km.
According to the characteristics that the landform at both banks is flat, when theconstruction access road is built, the drainage ditch will be excavated at both sides;besides draining the surface runoff from both sides of the construction access road andthe rain on the road surface, it can be used as the boundary ditch for the farmland andthe road to prevent the vehicles for construction from damaging the farmland at the sideof the road. The drainage ditch shall connect with the existing channels. The drainageditch will adopt trapezoid section, the bottom is 30cm wide, it is 30cm depth and theside slope is 1: 1; the internal wall shall be tamped (the quantity of bill of drainage pitchhas been included in the main works, it will not be calculated and listed out in thisreports).
Considering the use period of the construction access road is four years at most and it islocated in the plain area, the trees shall be planted at both sides of the constructionaccess road; since the conservation of soil and water by trees has a certain posteriority,at the same time, it is bad for leveling up and plowing the land again in the late stage,therefore, as to the vegetation measures for the construction access road, it mainlymeans planting grass. The specific measures is to plant the seeds of bermuda grass at theinternal sides of the drainage ditches at both sides of the access road according to 0.5mwidth to protect the side slope of the subgrade.The hardening layer on the surface layer of the construction access road at the left bankshall be cleaned up and be leveled up with the construction site for second plowing; thethickness to be cleaned is 20cm; as the permanent management area, the constructionaccess road at the right bank shall be reserved for use.

2.2 Measures for environmental protection in the stage of
operation
2.2.1 Protection measures for aquatic environment
(1) Measures of preventing oil seepage of the pivotThe unit selected shall not seep the oil; at the same time, the seeped oil collecting pitand accident treatment basin shall be arranged in the workshops; meanwhile, theoil-water separator shall be provided to treat various seepages and the oily sewage.
(2) Treatment of the domestic sewage in management stationSecondary sewage treatment system shall be provided in the management station. Thesewage in management station will be discharged into the domestic sewage treatmentstation after pretreatment in septic tank; as to the secondary treatment of the sewage, itwill adopt the embedded domestic sewage treatment unit. The main process flow ofsewage treatment is as follows:
Domestic sewage s t isterilizatio Discharge
(3) Treatment of waste water from the shipStrengthen the control over the domestic sewage and oily sewage; the ship shall beprovided with necessary domestic sewage treatment facilities and oil-water separatoraccording to the requirements of the related authorities; it is forbidden to discharge
21
sewage fi-om the ship in the reservoir area.
As to the domestic garbage from various ships. the storage cabinet shall be provided onthe ships; the domestic garbage shall be collected in the form of centralization and thenwill be sent to the garbage treatment site on the bank for treatment.
2.2.2 Treatment measures of solid waste
The domestic waste in the management station will be collected in the garbage can andthen will be transported to the urban garbage site for treatment.
2.9.3 Ecological environment
(1) Terrestrial ecological protection( strengtlheni the construction of ecological protection forest system around the
reservoir, effectively manage the various plants in the reservoir bank and the green area;if the dead tree is found, another tree shall be replanted in time.( as to the production migration area, control well the development scale of the land,prevent the excessive development of the farmland in the reservoir area and prohibitdestroying the existing woodland.Q) Recover the vegetation in the wash land and put an end to opening up wasteland onthe wash land so as to prevent the landslip and collapse of the river bank.(2) Protection of animals(O Strengthen the protection of the wild animals in the reservoir area and arrangepersoinel to protect them to prevent wide animals from being porches for.(2, Since the bottomland at the river valley is inundated, the kinds and the amount ofthe birds in the reservoir area will inevitably reduce. If the measures of buildingartificial watersplash zone are adopted and the sites for the birds for activities andseeking for food are increased, the influence degree will be reduced.(After water- retaining of the dam, most of the animals that previously resided aroundthe river banks will migrate to other places quickly, while there will be some animalsstaying behilnd looking during the primary period of water impounding to see whetherthey can adapt to the new environmenit. In this period, it is necessary to organize peopleto patrol for protection so as to avoid any animllal hunting in the chaos of the animals orexcessive distuLrbing. This will help to ietain more animals to live in the reservoir area.
(3) Protection of fishesIn order to thoroughly make clear the influences on the ecological and fishery resourcesin the water area from this project, the environmllent administrations of the project shallassist with the aqulatic product departmenits in further monitoring so as to obtain thecomprehensive data and provide basis for making reasonable measures. Fishway andFish protection station shall be constructed and completed together with the main-bodyprojects and put into operation at the same time.
If the fishes are not proliferated manually in the reservoir, there will no fishes forfishing gradually. According to related information, the process of nutrient enrichmentin some areas is very quick after the reservoir is built. mainly because the phytoplankton
22)
incr-eases rapidly vhile the silver carp and bighead carp directly USing/ the phvtoplaniktoniare in sei-ious lack. the ph,ytoplaniktoni as the second link in the aquatic or-gallisrn foodchaini can be bred. Since the phytoplankton is largely bred and t can provide a lot offeedstuff for the fishes; if they are not used, the fished will die, in this way, it willinfluence the water quality. Therefore, it is suggested by the experts that a large number-of Fishes that eat the phytoplaniktoin shall be put into the reservoir, especially the localfishes. The local kinds mainly include Yichang dolphinfislhes, Makou fish, bream.crucian and so on; in light of the kinds weifed in the present stage, thev are the mainkiinds in this area.
They can purify the water quality to keep the amount of the fishes in a stable level;otherwise, the fishes in the reservoir will reduce rapidly and it will influence theecological water environment.
Artificial aquiculture is one of the effective methods to proliferate the fish resources,mainly used for proliferating the resources of the freshwater- fish and the migrating fish,with good effect. Taking Taihu Lake as an example, since the water conservancy wasbuilt and the dam was built on the riverway, the passage for the migration of the fishwas interrupted, the four domesticated fishes cannot reproduce by themselves ; theoutput of the fish abruptly has falled down from 1 950s; however, since the kinds and thequantities of the small rough fish increase, the composition of the fish meets withchanges. According to the infomnation about the feedstuff in tlle water area,ichthyofaunia composition, economic benefit and the probibality of the fish fry breeding,the four domesticated fishes are selected and are put into the water area with the size ofI 3-16cm, good effects are achieved. Fish protection station shall be proliferate the foul-domesticated fishes.
Fish,x'ay will reduce the influence to migratin(g fish.
2.2.4 Conservation of water and soil(1) The repairs of the facilities of the maini works and conservation of water and soil, aswell the nursing of plants shiall be caiied out;
(2) It is to enhlanice the afforestation of the office and residenitial areas.
I.5 Environmnental sanitatio(1) Workers and nearbv residenits of the reservoir shall receive periodical randommedical checks.
(2) It is to unldertake periodical activities of w\iping OLit mosquiitoes. mice and flies.
2.'.6 Environmirriental geology
It is required to unldertake periodical m-ionitoring and mainiteniance of the stability ofreservoir banlks in the protectioni area. Any danigel-ous conditioni must be treated onemergency basis.
2.2.7 Material stackinlg vards
(I ) It is requil-ed to make good mainitenance of thc vegetation on the waste fields so thatgood ve-etation covering rate can be ensured-
(2) It is required to enhance the mneasures for conservation of water and soil in the wastestone fields until the ecological environment turns stable.(3) It is needed to strengthen the repairs on1 the waste blocking darn in the waste fieldsso to avoid collapse.
2.2.8 Electric power line
(1) It is reqLuil-ed to provide frequent repairs on1 the works of water and soil conservationand nursinu of the v\egetation.(2) It is requiled to strengthen the monitoring of electromagnetic radiation. In caseelectromagnaetic radiation caused by power supply line is found, necessary measuresmust be taken.(3) Sound isolation devices shall be installed for powerhouse and kept maintainedregularly.
2.3 Environmental Protection Measures for the EnvironmentalSensitive ZoneThe nearest distance between the sensitive points of atmosphere and acousticenvironment involved in this project and the site is about 600m, and the pollutioninfluences will not be brought about after operation of the project; the protection shallnot be carried out in operation period.
The nearest distance between the water catchment of the domestic water at the upperreaches of the site and the site is 1 5Kim the influence on water catchment is positiveafter the operation of the project and bad influences will not be brought out. Therefore,it is not niecessarv to carry oLut protectioni in operation period. As to the water catchmnenitof the water for industrv near to the site, it is not necessary to carry out protection aswell
In view of the importance of the above-mentioned domestic water and industrial waterto the residenits and the industries at the upper reaches of the site, it is necessary tostrengthen the cont-ol over the ship coming and going in operation period to prevent theoccurr-enice of the pollution accidents.

3.1.3 Environment Monitoring Plan during the Operating Period
(1) Monitoring of the Water Quality
The change of the water quality at the inlet of the reservoir, in the reservoir and at theoutlet of the reservoir after the reservoir is built must be monitored. If the result showsthat pollution is aggravated or over the limit, timely report to the environment protectionadministration must be made in order to adopt the relevant measures for controlling thepollution sources and to guarantee the water quality to reach the function standard asregulated.
Layout of the Sections for Monitoring: the principle of the layout is to control thequality of the water source from the upper reach of the river, and that of the water in thereservoir and that at the outlet of the reservoir. Five sections are to be laid out in the
32
following places: No.4 Water Plant section (17 km upstream of the dam site); QianyingSection (6km upstream of the dam site and Yujiahu section (1km downstrearn of thedam site).
Monitoring Frequency: one monitoring each during low flow period, level period andhigh-water period; three days running each time for sampling at sections of the right,middle and the left.
Monitoring items: totally 7 items, including water temperature, pH, SS, DO, CODmn,BOD5, ammonian.
(2) Monitoring of Water Temperature
After the Project is completed, the water temperature will show its firm layeredstructure. At that time monitoring of the vertical layered structure of the watertemperature must be performed and the temperature of the flow or drain must bevalidated in order to adopt measures to reduce the influence on water for industrial andagricultural uses at the lower reaches of the river.
Monitoring of the water temperature structure is to be done within the five verticalobservation lines distributing in the left, middle, right zones of the dam and in thereservoir and at the tail of the reservoir.
Monitoring frequency: the observation period is 5 years and the time for the same termobservation is the fifth day, 15• day and 2 5th day of each month at 8:00.
Monitoring items: the water temperature and the runoff at the outlet of the power station,the vertical water temperature of the reservoir, the water temperature and runoff at theinlet, the air temperature in front of the dam, water level, etc.

Time and Method for Monitoring: as per the relevant requirements in Methods forMeasuring of Environmental Noises in Urban Area (GB/T14623-93).
(4) Monitoring of public health (epidemic situation)
The change of the environmental conditions after the reservoir is built may place apremium on the prevalence of a certain infectious disease, therefore it is necessary tocarry out the monitoring among the inhabitants so as to discover the epidemic situationin time and to prevent the prevalence and to reduce its effect on them.
Monitoring items: diseases of historically high incidence, such as dysentery, malaria,
33
viral hepatitis, etc. and the breeding of flies and mosquitoes around the reservoir and thedensity of rats.
Monitoring alternative: general examination to be done regularly for public health in thereservoir area combined by positioned monitoring based on tracing.
Qianying Team No.5 and No.6 are the monitoring points for tracing.
Requirement for monitoring: one evaluation to be performed for epidemic situation andthe popular examination of the public health of the reservoir area after functioning ofthe reservoir and hereafter once every three years. The monitoring period will last for 10years. The investigation of epidemic situation must be well done for the traced publicand file management must be set up for the epidemic situation. Investigation andanalysis of the varieties, density and multiplying of the mass media of the diseases inthe regions to be traced for monitoring must also be done.
(5) Monitoring of stability of reservoir bank
Monitoring will be done in successive four years since the functioning of the reservoir.
(6) Monitoring of water and soil erosion
Monitoring period will last for 10 years. The first monitoring will be performed at thefirst year of operation period and hereafter once every three years.
(7) Monitoring of Terrestrial Ecologic System and Land Resources
This monitoring is to be done for investigation of the influence on the regionalterrestrial ecosystem and the use of the land resources due to the reservoir flowage andimmigration cultivation after the operation of the reservoir.
Irregular investigation must be done for the percentage of coverage by vegetation andthe change of the community of the terrestrial plants and animals and their diversitychanges, with the emphatic observation of the backwater region of the reservoir.Another irregular observation and investigation of the modes of land use and the changeof the utility benefit, conditions of soil erosion and soil fertility in the reservoir area andin the host area. For the soil gleying and the secondary salinization in the regions aroundthe reservoir and the region near the backward position, the irregular observation mustalso be performed.
(8) Monitoring of aquatic ecological system
The investigation will be undertaken on fishery output, fish varieties and quantities. Theinvestigation period will last for 5 years.
(9) Monitoring of other construction sites
As for the construction situation of the reservoir, lower reaches, material stacking sites
34
and waste fields, aquatic eco-svsteml and Terrestrial eco-svstem. the supervising aLncd themanagerial staff of the environmental protection departmiienit of the project must miakesdaily inspectioni of the sites, so to have direct views of the gener-al envir-onmiiienital quality.promptly discover environmental problems and analvze theil- developing tendency.

3.3 The Legal Forces for Environmental Protection Action PlanEnvironmental protection action plan is regarded as the guide for construction units to carry outthe environmental protection measures. It is also the basis for environmental competentdepartments to inspect and approve the works of environmental protection. Therefore, theenvironrmental protection action plan must have the same legal forces with the contract andbidding documents.
When the project employer intends to invite public bidding of the project construction, theenvironmental protection action plan shall be treated as one of the basic bidding documentssold to the bidders. It must be included in the bidding documents, of which, necessary chargesrequired by various environmental protection measures can be listed in the construction budget.When the project employer examines the bidding documents, it must consider the commitmentspecified in the EAP as one of the basis for document examination. When signing constructioncontract, it must include EAP as one of the works included in the contract. It should clarify thatEAP is one of the basis for approval of the project quality, any environmental losses due to thefailure in fulfilling EAP shall be borne by the contractor. The personnel in charge of the ProjectOffice must acquire to well know the significance of EAP before project commencement andshall be responsible for making explanation to contractors.
47
The project supervisor must treat EAP as one of the basis for the supervisory works. Any worksthat have not fulfilled the environmental protection measures cannot be approved.
The contractors must assign special personnel to be responsible for the implementation of theEAP, formulate the alternatives of EAP implementation. All measures specified in the EAPmust be carried out thoroughly according the schedule.

4.0 ANALYSIS OF ECONOMIC LOSS AND BENEFIT
OF ENVIRONMENTAL IMPACTS
4.1 Analysis in Environmental Economic Benefit
4.1.1 Social Benefit
Cuijiaying pivot is a water conservancy project, which mainly serves for navigationand meanwhile gives attention to comprehensive benefits such as irrigation, tourismand aquaculture. Therefore, benefits of this project include navigation, powergeneration, farmland irrigation, aquaculture, tourism, etc.
Cuijiaying pivot possesses comprehensive benefits such as navigation, powergeneration, irrigation, aquaculture and tourism. Implementation of this project willnotably improve the navigation condition in the middle and lower reach of HanjiangRiver. 39.8Km of reservoir backwater will inundate 4 clusters of beaches in thereservoir area and increase the navigation level of this reach up to 1 000t, which savesmaintenance cost of the waterway. Besides, raising of water level in the reservoir willsave dredging cost for Xiangfan Port on one hand, and on the other hand will boostthe economy there, so it has obvious social benefit.
The annual energy output of this project is 4.15 X 1 08kw * h; according to the presentsituation, the quantity of electric charge per 109 kwh in Hubei is equivalent to RMB1,016,000,000.00 industrial output, in this way, this project provides the necessarycondition for creating the industrial output of RMB 4,210,000,000.00.
As for the notable benefit of power generation, this project generates annual poweroutput of 4.15X 108 kw * h, which creates essential conditions for 4.21 billion ofindustrial output value according to the fact that electric quantity of every 0.1 billionkw * h equals to 1.016 billion of industrial output value at present in Hubei province.Apart from that, using the direct financial income created in power generation fordynamic development of the waterway will ultimately solve the problem of financialstrain for the waterway construction.
Implementation of this project will improve the farmland irrigation condition inTangdong irrigation area with effective irrigation area of about 177 X 104mu, andreplace the irrigation compensation project for the implementation of midline projectof the south-north water transfer strategy.
In addition to the above social benefit, this project will also create considerablebenefit for tourism, aquaculture, etc, which is mainly reflected by the fact that
51
upgrade of waterway level and establishment of Yuliangzhou scenic spot attract moretourists, and the completion of Cuijiaying pivot will provide favorable water space tothe development of aquaculture in the reservoir area.
This project will provide necessary transportation conditions to the lineal economicdevelopment, especially to the construction of Xiangfan city because the raise ofwater level in Cuijiaying pivot will improve conditions in Zhangjiagang water areaand Tangbaihe river mouth, which will promote significant economic development inXiangfan as well as in the base of China's Second Automobile in Xiangfan.
As the absolutely necessary compensation project in the midline of south-north watertransfer strategy, the flier canalization project in the middle and lower reach ofHanjiang River, if completed early, will provide a solid base for realization of thismagnificent blueprint with great comprehensive benefits.
On completion of the navigation hydropower pivot, the increased amount ofimpounded sand and low water flow rate will improve water quality in the lowerreaches of the dam site. In addition, expansion of the water surface will regulate theclimate, promote growth of various plants, and increase the plant coverage in thereservoir area.
In general, after the flow off of Cuijiaying pivot flows across Danjiang Reservoir inthe upper reaches being regulated and stored, the riverbed and flow off becomerelatively stable, which will provide convenient transportation on land and water andpossess the advantages of adjoining power utilization load center, having wideriverbed in the construction area as well as short construction period. This project is infavor of the implementation of the midline south-north water transfer strategy.
4.1.2 Economic Benefit
Direct economic benefit brought by this project mainly lies in decreasedtransportation cost, power generation, etc. Other benefits such as irrigation, floodcontrol, tourism, aquaculture and poultry, and improvement in local investmentenvironment are difficult to quantify, so following below is just some qualitativedescription.
(1) Navigation BenefitImplementation of this project will notably improve the navigation condition in themiddle and lower reaches of Hanjiang River. 39.8Km of reservoir backwater willinundate 4 clusters of beaches in the reservoir area and increase the navigation levelof this reach up to 1 000t; improve the condition of Xiangfan Port, realize the opennavigation between Xiangfan and the north effluent of Tangbaihe River all the yearround, which saves maintenance cost of the waterway as well as dredging cost forXiangfan Port. Therefore, the navigation benefit of this project is mainly represented
52
by the increased freight volume and decreased transportation cost, as well as themaintenance cost, which will be saved by the replaceable waterway regulation projectafter completion of construction project.
(2) Power BenefitThe shadow electricity price of this project shall be set down on the basis of long-termmarginal cost of the power supply system i.e., the increased system capacity cost andelectric quantity cost caused by the increase of unit loading.
(3) Irrigation BenefitAfter completion of midline south-north water project, there will be no transition ofmedian water period in the lower reaches of Hanjiang River because of the quickenedhydraulic drop from high water to low water and shortened time in median water,which will cause adverse impact on the farmland irrigation in the middle and lowerreaches of Hanjiang River (esp. Tangdong irrigation area of Xiangfan). Relevantsurvey data show that if Cuijiaying reservoir pivot is not built, it will cost RMB0.3billion to build a channel linking Danjiang river mouth and Tangdong irrigation areato solve farmland irrigation in that area. However, after the completion of Cuijiayingreservoir, due to the raised water level, irrigation conditions in Tangdong irrigationarea will be improved with effective irrigation area of 177 X 104mu, which will saveinvestment in construction of the irrigation channel. Substitution effect made byirrigation in this project equals to the investment in the irrigation channelconstruction.
(4) Aquaculture BenefitOn completion of Cuijiaying pivot, backwater length of the reservoir area will be39.8Km, and the water area can reach up to 7.4 X 104mu if the average river surfacewidth is 1.5Km, in which, 1 X 104mu can be provided as area for manual aquacultureand poultry in the reservoir area, and 6.3 X 104mu for fishery for fulltime fishers. Tocalculate in term of 100mu as cage culture area in the reservoir area and 4 X104Kg/mu as per unit area yield, the annual production of adult fish will be 400 X104Kg; in term of 1 X 104mu as enclosure culture area in the river port and 1 00Kg/muas per unit area yield, the annual production of adult fish will be 100 X 104Kg; in termof 6.3 X 104mu as natural fishery water surface and 14Kg/mu as per unit area yield,the annual production of adult fish will be 882,000Kg. The above three items total588.2 X 10 4Kg of annual production of adult fish, which, if calculated in term ofRMB10/Kg, will create an annual production value of RMB58,820,000. If deductedthe investment cost of aquaculture, the aquaculture benefit of Cuijiaying pivot innormal years can reach RMB 10 million/year.
(4) Tourism BenefitApart from aquaculture benefit, the natural and geographic conditions in HanjiangRiver will bring notable economic benefit to tourism in Xiangfan with not onlycultural relics such as the ancient Longzhong and ancient city wall, but also newly
53
opened Yuliangzhou scenic spot, which has become a fresh attraction to urban people.CuijiayingJ pivot is situated in the lowver reaches of Yuliangzhou and the constructedreservoir will be integrated witlh this scenic spot, creating a large-scale recreation siteproviding reservoir scenery as well as water amusement. Beside considerable tourismbenefit. this reservoir will also add new tourism routes for tourists.On completion of the navigation hydropower pivot, the increased amount ofimpounded sand and low water flow rate will improve water quality in the lowerreaches of the dam site. In addition. expansion of the water surface will regulate theclimate, promote growth of various plants. and increase the plant coverage in thereservoir area.
4.2 Analysis of Loss of Environmental Impacts
The constructioln of dam without adopting relevant protection measures may causeenvironmental loss, which includes mainly the discharge of pollutants during theconstruction period, the upraise of incidence of diseases among the constructionworkers, the interference of the growing environment of animals and abusive killingof them. the obstruct of the dam, the serious damage to the growing environment offishes and flooding historical cultural sites due to the water flow from the dam and thepossible blowup of the growing environment for flies and mosquito that spreadmalaria.
Other disadvantageous impacts on environment can be avoided or dulled throughadopting measures. The environmental loss is about equal to the total sum of the costof protection measures for disadvantageous influence and the relevant monitoring costof environlmental protection and control.
The total investment on environmental protection will be RMB 40.3354 million andthe ann1ual environimental control and monitoring charges will be RMB 2.88 millionIand training charges of RMB 0.79 million duLing the operation period.
4.2.1 Analysis of' Envir-onmllenital Econiomic Loss
Environmental economic loss includes the necessary investment for avoiding orreducing the loss, totaling RMB 32.712 million. The average annual value of loss isRMBI.636 million during 20 years' operationl.
4.2.2 Analysis of Environlmenital Economic Benefit
(1) Water power is to be used as the clean energy sources, which can greatly reducethe discharges of the three wastes, and its environmental benefits can be calculatedbased on the equivalent environmental investment for using- thermal electricitygeneratin g planit on1 the coequal scale. which can be saved if water power is used. Thecalculation is as l'ollows: the annu,al standard consumptioll of coal is 112 thousandtonls based on the standard consumption of 0.35kg per kw *h, and the annual discharge
54
of sulphur dioxide will 2.707 thousand tons based on the percentage of the sulphurcontent of the local coal, 1.51%, upon which RMB 0.2/kg is levied as the dischargefee for sulphur dioxide, so making a sum of RMB 542 thousand to be paid for the
discharge fees for sulphur dioxide every single year. A rough estimation of the cost ofa set of electrical dedusting equipment is RMB 2.97 million for treatment of soot,which must be added by another sum of RMB 0.66 million for two tippers of 8 tonsfor moving the fly ash collected to the fly ash yard because of the use of dry dustingwithout ash sluicing water. As for the construction of an ash yard, the investment ofRMB 25 million is needed. Therefore, the annual investment for E.P. will be
RMB1.909 million if the E.P. establishments can be used for 15 years. The operatingcost of environmental protection facilities is RMB 250 thousand each year.
So it can be calculated that RMB 2.159 million can be saved each year after operationof the project.
4.2.3 Analysis of Loss and Benefit of Environmental Economy
Ratio of Loss and Benefit = value of annual environmental loss / value of annualenvironmental benefit
The annual average environmental loss is RMB 1.636 million and the annual average
environmental benefit is RMB 2.159 million, so the ratio being 1:1.32. Therefore, theeconomic benefits brought by the environmental investment is larger than theenvironmental loss and remarkable social benefits and environmental benefits areshown as well.
