Environmental Impact Assessmentfor North-River(Shaoguan-Qingyuan) Waterway Regulation Project

0. Preface

The North River, running from the northern part of Guangdong Province to the Pearl Delta, is the secondlargest river of the Pearl River system. The navigation in the North River is a traditional way in the twomountainous municipalities of Shaoguang and Qingyuan. The waterway transportation in the NorthRiver (Shaoguan-Qingyuan) plays an important role in the local social and economic development, andis becoming busier and busier.

It is efficient and urgent to improve the North River waterway for the local social and economicdevelopment and resources utility, especially for improving local economical conditions of themountainous areas presently backward. Therefore, Guangdong Province Waterway Bureau decided toregulate the waterway of the North River (Shaoguan-Qingyuan). Inland River Design Institute ofSichuan (IRDISC) undertook the feasibility study. The project applied for loan from the World Bank.

It is required by the World Bank and laws and regulations to make Environment Impact Assessment(EIA) for the Project. In January of 2001, Guangdong Province Waterway Bureau (GDWB) selectedSouth China Institute of Environmental Sciences, SEPA (SCIES) to undertake EIA study for the project.This TOR for EIA of the project is based on the data and information provided by GDWB, field surveys,and requirements of World Bank EIA Guidelines and national EIA Guidelines. The Approved EIAOutline by State Environment Protection Administration (SEPA) will be the basis of the EIA study forthe project.

The EIA Outline was examined by State Environment Protection Administration (SEPA) on the 23rd -the 27th May, 2002 and reviewed by the experts of World Bank on the 16th of April and 17th of July,2002. The revised TOR will be the basis of the EIA study for this project.

1.5.1 Assessment ot critical issues

For a waterway project, the EIA for the project will focus on:

1) Surface water environment impacts in the Cc 1'! t'LuCi'n 11p,IiaQ;

2) Aquatic ecological environment impacts in the tvonsIuitnl uc;tio

3) Indirect impact of the project, including the impact on the economic activities in the northern regionof Guangdong;

4) Public Consultation for the project;

1.5.2 Assessment Grades

According to the classification principles for EIA in the "Environment Impact Assessment TechnicalGuidelines" (HJ/T2. 1-2.4, 19) issued by State Environment Protection Administration and the"Guidance of EIA for Inland Waterway Projects" (JTJ227-200 1) issued by Communications Ministry,the assessment grades of the project are as follows:

TheAssessment of Water Envionment

The "Environment Impact Assessment Technical Guidelines" (HJlT2.3, 93) says "water environment

a

Environmental Impact Assessmen for North-River(Shaoguan-Qingyuan) Waterway Regulation Project

assessment grade is decided by three factors: the amount of wastewater from the project, pollutants andtheir concentrations in the wastewater, and the scale and water quality targets of the water bodyimpacted by the construction phase.

Water environment impacts of the project are caused mainly in the project period. In the project life, thewater environment impacts of the project is compounded by the facts that suspended solid concentrationin the North River will be increased by dredging and shoal blasting, the operation of dredging ships andmachines will produce effluents and wastes, and construction camps into the river will contaminatewater. The effluent amount of the project will be small. The water environment impacts in the operationphase will be light; the water pollution will be slightly caused by ships and the pollutants will come fromships. However, the water quality in the North River is required to meet a high standard, because a partof the project area belongs to the drinking water sources and fishery resources protection areas.Therefore, the water environment assessment of the project is classified to category 2 with reference tothe technical guidelines for EIA issued by SEPA.

Ecological EnvironnentAsressnen1

The comments on TOR for EIA of the project from SEPA require that, to effectively protect fishresources habitats and spawning areas in the no-fishing areas established in the North River by QingyuanMunicipal Government, Category 2 is applied to the ecological environment assessment of the project,with reference to the EL4 Technical Guidelines - Non-pollution Ecological Impacts issued by SEPA

(HJ/TI 9-97).

Environmental impact Assessment for North-River(Shaoguan-Qingyuan) Waterway Regulation Project

2. Project Description

2.1 Project Location

The Shaoguan-Qingyuan section of the North River, 184 kilometers long, winding through the canyonsand basins in the northem part of Guangdong province, is the midstream of the North River. Its

geographical coverage is east longitude 111 50' to 1 14° 50', north latitude 23° 40' to 25° 40'. The

river course for regulation is from Shaoguan downstream to the Qingyuan North River Highway Bridge.The location of the project is shown in Figure 2. 1.

2.2 The Construction Scale and the Design Standard of the Waterway

The channel may arrive at Grade V through renovation. It is possible for channel Dimensions to

amount up to 1.3x40x260 meters when the guarantee rate of the comprehensive stage duration curve

method is 95%. The passage capacity of the channel exceed 1.13million tons when the self-propelledbarge of 30(Q-ton capacity or the fleet of 2x300-ton capacity passes through the channel.

2.3 Cutrrent Statuis

2.3.1 "Current Status of Waterwav

Three dams were constructed in the middle section of the North River (Shaoguang-Qingyuan section) in

1990s. They are Mengzhou-Dam, Baishiyao-Dam and Feilaixia-Dam( 1:igure 2.2). The Dams turned this

reach into all-year-round headbond area, fluctuating hcadpowd zone and downstream reaches ofprojects.The channel in the hicadpoiid area can be open to navigation of over-500-ton ship all year round

because its water body is broad;water flows smoothly and water is deep and abundant.

The channels in fluctuating head pond zone are influenced both by fluctuating lheaidpond of each project

and the unsteady flow of power hump modulation in upper stream project. The average range of water

level is between I meter and 3 meters. Rapids appear when the water level is low when the former

regulation structures have lost their own functions and hamper the safe and regular navigation of boats

(ships). Therefore, the reaches in this zone can only be to navigation of about 100-ton ship. They are

navigable for over 100-ton ship only in the midium flood period or abundant discharge period.

The downstream reaches of projects enjoy the same features as those of rivers in mountain areas orplains. River courses are valley-like or spacious. Due to the influence of \ itriaLbk tl.m, channels changegreatly and navigation conditions are bad. Currently, the channel maintenance standards are as follows:102-km-long navigation area from Shaoguan to Yingde city is grade VII channel installed with type III

navigation mark whose dimensions are 0.8*15*90 meters. It is the navigation for 50-ton ships.22-km-long navigation area from Yingde to the mouth of Lianjiang River is grade VIl channel installedwith type I mark whose dimensions are 0.8*15*120 meters. It is the navigation for 50-ton ships.

60-km-long navigation area from the mouth of Lianjiang River to Qingyuan city is grade VI channel

installed with type I mark whose dimensions are 1.0*20*120 meters. It is the navigation for 100-tonships.

2.3.2 Current n)oit facilities :.. Harbors

There are important purt illcilitiQs such as Shaoguan port rct.iiitics, Yingde porl lit6litics and Qingyuan

pofrt tciIicics. (Figur e 2.2) Besides, there are many small wharfs of towns scattering within the area of

the Middle Reach of North River. The total amount of purl tltcilitics and wharfs (including small ones) is20 within this reach. These three harbors mentioned above begin to take shape, which own some

handling machinery, backup site, warehouse, container yard and convenient handling. However, its

capacity is still far from the shipping requirement in this area according to the current statistics of theshipping goods and its increasing tendency. It's imperative to renovate those small wharfts (callingspots), which have no handling machinery and backup site.

2.3.3Baseline Waterway Transportation

The boats and ships running in the waterway have the capacities of 100 tons to 500 tons. The numbers ofboats and ships and tonnage have been increasing rapidly in the past years. In 2000, the traffic in thewaterway is 1,300 boats or ships, with total 129,000 tonnage, shipping total 6,040,000 tons of goods.

(1) Cargo carrying capacity and vessel types:

The cargo carrying capacities for the three sections at Shao-guan, Ying-de and Qing-yuan respectivelyare put forward according to the project's feasibility study report. Vessels available locally have a cargocarrying capacity of 100-500 tons. Among them, 70% of these vessels have a cargo carrying capacity of200 tons or so. Based on such data, we can make a rough estimate of the runs of vessels in each riverreach. See the estimations in Table 2-3-1.

(2) Types of cargo

The section General Engineering Conditions has given detailed explanation on types of cargo to betransmitted in the waterway in the middle reaches of North River, mainly including coal, cement & mineconstruction materials. Cargo of other types ranges from machinery/equipment, electrical appliances,agricultural & sideline products, industrial chemicals, light industry products, to pharmaceutical productsand non-ferrous metal etc.

(3) Dimensions of exiting ships

Dimensions of exiting ships are listed in table 2-3-2.

2.3.4 Water-Pumping Spots

According to the recent investigating, there exist 57 \'1'"1 kk :;li!iic;c, along the Shaoguan-Qingyuansection of North River. They are equipped for drinking, industrial and irrigation use, but most of themwere built in all-year-round hszidtlpaiJt area in 1960's -1990's and parts of them have been stopped fromusing now. They are shown in

2.3.5 Dykes

Investigation and field survey shows that all existing dykes can meet flood prevention standards after theproject is completed; and no civil works is required. However, some natural banks exists along themiddle reach of NorthRiver and they are easy to be destroyed by the impact of flood, so bank revetmentsneed to be constructed to prevent waterway from being chocked with soil/sand from ho!1. ive,oi.

2.4 Necessity of Proposed Waterway Up2rading

2.4.1 To speed up economical development of this area requires the water upgrading

As one of the most developed regions in economy in Guangdong province even throughout China, thePearl River Delta is in lack of raw materials and fuel. The raw materials lacked must be transported fromHunan and Jiangxi province, and all these materials were transported by ship through Beijiang Riverthrough the ages. The Pearl River Delta enjoys a rapid and sustaining economic development, thereforethe demand for raw materials and fuel provided from above provinces become larger and larger, and sodoes the demand of the freight volume undertaken by ship in Beijiang River. With the increasing of thewaterway transportation in the North River year by year, and the water carriage becominga majortransporting measures in this industrial developing zone, the waterway in the North River must bewidened and the navipational channel upgraded.

The waterway form Shaoguan to Qingyuan in the middle reaches of Beijiang River is a "GoldWaterway" in the territory, therefore using a relatively small investment for channel upgrading in keyand difficult sections and improving navigational conditions is a simple investment of low cost but withsignificant return, and also is very necessary in order to speed up the economic development within thisarea.

2.4.2 Regulation is the necessary ontion to improving the conditions of the waterway

There are three key river control facilities in the middle reaches of Beijiang River including Mengzhouba watercontrol dam with navigation shiplocks, Baishiyiao water control dam with navigation shiplocks, Feilaixiawater control dam with navigation shiplocks built up successively during 90s' of the 20th century. The generaldescriptions of these projects are as follows:

(I) Mengzhouba Project

15


This is a project ofGrade m and it's control is by nmoffriver reaation alldav. The ship lock is a singl-line and grade1. The lock chamber is an integrated structur whose dimensions are 140*14*2 merters Oength*width*water-depth of

gate). The lock chamber is decorated with 2*7-pair floating loops linking boats.

(2)Baishiyao Project

The project is a project of Grade m and it's control is by runoff river regulation all-day. The ship lock is a singl-line

and grade 1. The lock chamber is an integrated structure whose dimensions are 140*14*2.5 merters.

(length*width*water-depth of gate).

(3)Feilaixia Project

The project is a project of Grade I and it's control is by nnoff river regulation all-day. The ship lock is a singl-line and

grade 1. The lock chamber is an integrated structure whose dimensions are 178*16*3 merters.

(length*width*water-depth of gate).

The Midlle Reach of Beijiang River is open to navigation all year round with clear channel and busy transportation.

Three key water control projects mentioned above were built in 90's. Significant variations in river flow in the

downstream area since commissioninp of the three dams has resulted in significant changes to the

downstream channel (configuration, sediment dynamics. etc.). The long-term impact has been greatly

restricted navigation. In contrast, the navigation condition in reservoir is excellent, because the headpond area is

deep and abundant with water all year round, and more over, the channel here is broad. AU in all, regulation is

absolutely necessary for improving the condition of the waterway.

2.4.3 The Proposed Waterway Upgradini, Project and its Effect on the Overall

Transportation System

The middle reaches of Beijiang River, Jing-Guang Railway and its extension to Shen Zhen and Kowloon,

State Highway 106 and 107, Jing-Zhu Express Highway as well as Guangzhou Baiyun International

Airport has built up an important transporting networks passing through Middle-North China vertically

and horizontally. The proposed Beiiiang Waterway Upgrading Proiect will be implemented in phases.

Through the water-transporting networks among Beijiang, Xijiang and Dongjiang Rivers, the coverage

of economic zone of the Pearl River Delta will be enlarged into the area where the three rivers can

access. And by combination of sea transportation, united carriage channel passing through different

areas with long distance can be built up; this will shorten transporting distance from the producing area

of raw materials, fuel and other products to the place where the said products are consumed, thus to

reduce producing and transporting cost, and it plays a very important role for the sustainableeconomic

development of Guangdong province, especially in North-Guangdong area. In addition, the water

carriage channel can fetch up the disadvantage of railway and highway for transporting some low-valuematerials and super big cargos. Therefore, the exploitation and construction of navigation in the middle

reaches of Beijiang River can make the comprehensive transporting system more complete, and the

distribution of networks more reasonable. The waterway upgrading of 184 km from Shaoguan to

Qingyuan is one part of the exploitation and construction of the main stream of Beijiang River.The

waterway upgrading of 74 km from Qingyuan in Beijiang to Sanshui Bayou was completed and accepted

smoothly in 2000.Anyway, the navigational conditions can be improved furthermore. Therefore, the

upgrading from Qingyuan to Shaoguan, and the extension of the main stream of Beijiang River will

enhance navigational capacity, and then not only the transporting frame by railway, highway and water

transportcan be built up. Also the technical expertise developed in waterway upgrading under such

conditions as the Beiiiang will serve to facilitate future waterway projects in the upper reaches of other

rivers with similar construction characteristics.

2.4.4 Proposed Waterway UpErading Will Promote Development of Tourism

According to the information provided by the tourist department, the tour resources of the cities

alongside Beijiang are very abundant. There are a lot of tour advantages and attractions in these areas,

such as centuries-old developing history, splendid antiquity culture, famous mountains, ancient temples,

green virgin forest. These abundant tour resources can be developed into tour items with differentcharacteristics, and will add new tour hot spots and touring routes in Guangdong province. And also,

16


Shaoguan and Qingyuan should have been one of the most important tour bases in Guangdong province.But because the traffic condition here is poor for the time being, the abundant tour resources have notbeen developed into a reality. For the future, along with the improvement of people's living standard,outdoor tour on weekend and holidays will become more and more popular; and people who would liketo return to the nature will increase greatly. Therefore, upgradine Beijiang waterway will solve theproblems caused by ships blocking and will bring up a flourishing development of water tour in BeijiangRiver.

2.4.5 Proposed Waterway Upgrading Will Facilitate Better Navigation

Because of the influence of flow control of each water-power station, navigational blockage is frequent,and sometimes phenomena of serious ship blockage and running aground occurred. According to theintroduction of the Qingyuan City Government, during 60 days of the lower water and average waterperiod of each year, ships stayed in this river section and created a new "Landscape" in Beijiang River.And the living sewage, waste water and garbage was discharged into this river section from about 100ships almost, this has made water quality exceeded specified standards seriously, this situationthreatened the water quality of water source in Qingyuan city and Qixinggang Water Factory inQingyuan city greatly. Therefore, upgrading Beijiang waterway is a guarantee not only to facilitatenavigation, but also to protect water quality of Beijiang River, avoid water pollution by ships and reducedeleterious environmental impacts too.

2.5 Project Scheme

This project is to improve navigation condition of the North River (Shaoguan-Qingyuan). The civilworks of the project are constructed in the follow river sections of the North River (Shaoguan-Qingyuan):three natural river courses (including Section A Mengzhouba Dam-Mengli, Section C BaishiyaoDam-Guanyinyan and Section E Feilaixia Dam-Qingyuan Beijiang Bridge), and two seasonallyfluctuating water level course(including Section B Menli-Wushinan and Section DGuanyinyan-Daluodu). This project mainly considered four kinds of civil works: groynes, spurs (showedfollowing drawingl - ) , retaining. bank- revetment, and dredging. Figure 2.2 and Figure 2.3a,b,cshows the civil works of the project. From upriver to downriver of the North River(Shaoguan-Qingyuan), an introduction to the project is as follows:

2.5.1 Section A Mengzhouba Dam to Mengli (Natural River) (about 30km) and

Section B Mengli to Wushinan (seasonal fluctuation course)(about 4km)

Totally 19 spots of dangerous shoals locatein a 32.1 kilometers long river course, which need to be regulated. Themain civil works is as following:

(1) To construct 116 spurs and groins, amount to 16.08 kilometers long and 471,500 m3;

2.7 Conditions of Engineering and project plan

2.7.1 Traffic Conditions of Engineering

19


On the basis of site inspections by Task-Group, it is known that the traffic along the Northem River israther convenient, on the east bank the main road is Yin-Ying (Qingyuan-Yingde) road (named S203),

and every village or town has suburban road connecting the dock on the both banks of the river, 65% of

the suburban roads are paved with concrete and others are paved with sand-stone, so it is sure that the

traffic can meet the demand of field construction and it is not necessary to construct extra traffic ways

and temporary docks or widen any road for the project. The traffic programming during the project is

shown in figure 2-3-a,b,c.

2.7.2 Conditions of Project Field

Characteristics of the project:

(l)Construction will be in low-water season, while the exposed bed of Northem River is wider than

usual and usually it is 4000-lOOOm wide, so it is rather good for the project. (2)The docks on both banks

are enough. The materials needed during the project can be conveyed by truck to the nearest dock and

then shipped to the construction field, thus much land will not be needed temporarily. Task-Group has

determined through investigation that the docks needed by the project would include Chetouzhou dock,

Baitu dock, Wushi dock, Kengkouzui dock, dock near Jiangkou town, dock near zhouxin town and so on.

These docks will be used for transmitted construction materials, mainly stone, and sandstone secondly.

The docks above-mentioned are showed in figure 2-3a,b,c. (3) There is enough land on both sides of

Northem River to be used as construction field for the storage of large stones temporarily, which are

needed by revetment project. The banks, which need much revetment, include the one from Wushi

Power plant to Wushinan, the one from Lunzhou (nearby Feilaixia) to Qixinggang, and that from

Hululing to Xiaoshinan (nearby Qingyuan Bridge). All temporary construction fields of the above banks

are arranged on the banks of the river. (4) Since the river is wide enough, the construction field is

scattered, and the constructions are well-arranged and strictly managed, it is assured that there is no

influences on normal shipment security and drainage during the construction.

2.7.3 Supply of materials, water and power

( I ) Local supply of construction materials: Construction materials needed by the project, like large

scale concrete, stone and sand, should be purchased in the nearest market as a rule, and the sources of the

materials are Shaoguan city, Yingde city and Qingyuan city, no more than 5-15Km far from the

construction fields. According to the consultation and investigation to local environment department,

country-land department and constructors of waterway bureau, all the stones needed for this project are

from local stone mines, belonging to local town or village (including Gantang Town and Chishui Town

of Shaoguan city, Baishiyao village and Guanyinyan village of Yingde city, Yuantan town of Qingyuancity), and runby private institute legally. There are no villages near the mines. The locations of the stonemines, for the project, are shown in figure2-3a.b,c and table 2-7-1 in detail. Due to the reason that we

only need a small quantity of sand for the project (about 2660 cube meters), the sand can be purchased

from the local legal provider along the bank of the river.

(2) Water and power supplies to the project: Water for construction can be pumped from Northem

River directly; and water after disinfecting and purifying can be used for household.; local power

transforming substations can supply power for the project.

2.7.4 Sediment Disposal

The plan for disposal of sediment dredged or excavated during the project is as follows:

(1) Because the main section of the middle reach of North River (Beiiiang) is much wider than design requirements(widest is approximately 1000 m) and because there are extensive shallow areas along both banks. sediment generatedby dredeing, both of the channel and during construction of the spurs and grvnes will be disposed in the shallow areasbetween the spurs. The deposition in these areas will further enhance the river regulation created by the spurs and thechannel dredging. No dredeed materials can be disposed on the riverbanks along the waterway.

(2) Sediment generated by dredging/excavation for channel re-aligrnent will also be disposed on the areas betweenthe newly constructed spurs and along the riverbanks. However, it is likely that little, if anv. of such materials willactually be dumped in the water.

(3) Proiect revetments will consist of stonework of 1.5 m height and a total of 20.000 cu m. From site inspections, ithas been determined that there will be little, if any. excess dirt created by the excavations.

According to the construction methods used in other projects, any excess dirt produced in the construction is usuallvused to infill wet areas or wasteland. As per proiect desien, the revetment construction will maintain the bank at its

original gradient The Project mostly includes clearing, off surface shrubbery/debris, and leveling up rough slopes withearthwork Thus any soils excavated, can be re-used as fill and the volume of waste can be reduced greatly.

The above disposal sites for dredged sediment and excavated soil spoil are mostly in the areas between spurs at

distances of spurs-fields 100-200m far from the waterway (as shown in Figures 2-3ab.c and Table 2-7-2.)

2.8Engineering Analysis of environmental impact factors

2.8.1 Main types of engineering work

A waterway regulation project usually adopts such engineering measures as damming (spurs andgroyne ), dredging, thus to reach the standard of inland waterway, aiming to widen the passageway,augment the specifications of waterway, guarantee constant water flow, hence regulate the water flowrate, and control the gradient ratio of the waterway to be less than the accepted value recorded by aself-powered vessel going up the stream, and improve the water flow to prevent traffic blockage fromarising in the waterway.

2.8.2 Main construction technologies and measures

2. 8.2.1 Dredging project

The dredging project mainly includes Dredging project on riverbed and Shoreline and channelre-alignment on land.

(I)Dredging project on riverbed

This part include dredging project on riverbed so as to obtain the depth and width standard in the project

design. The main working procedure is: digging sediment under water-Clearing-Slit-loading spoil

with barges( to be disposed in sites or be reused as materials for building) -dredging up waterway. Thepractical working procedure is to dig earthwork under water by dredger with 25-8.0m3 grappling bucketor 80-120m3/h sucker, then to dispose spoil in the spur-fields (area between the two spurs) as mannualalluvium project and to dredge up the navigational channel finally. The most earthwork-comes fromdownriver to Feilaixia, which is about 103 1,450m3, covering 27.9% of whole earthwork.

(2)Shoreline and channel re-alignment project

There are 5 sites needing Shoreline and channel re-alignment project in the whole waterway. This

project cuts the waterway with small curve semi-diameter to meet the demands of standards in the

waterway renovation project design. The main working procedure is: digging earthwork -chamfering

on land and dredging both sides of the cutting line-flowing the manmade-riverbed. The practical

working procedure is: taking advantages of mechanisms such as grab, bulldozer and vehicles as tools

and assisted by manpower, chamfering on land, while dredging up on the upward and backward to the

cutting-line by dredger, and finally new waterway passes through. The range between

Zhigaotan-Shitoushan (Mengzhou-Dam to Hutoushan section), with a 2.0km-long cutting-line and with

the most earthwork 247,800m3, (covering 22.3% of whole earthwork,) costs the most, and its spoil is

reused to refill Spur-fields. Other projects have comparatively less earthwork.

2. 8.2.2 Spurs/Groins project

There are 226 spurs/groins to be built in the project presentation. The total length is 46.71km and has an

earth-rock works of 1324,000 cube meters, including 210 Spurs and 16 Groins and I lockeing up dikc.

Construction sites are arranged in low water area usually. The main working procedure includes:

dredging trench - mattress paving - sand-cushion and jackstone paving. Because the root of

jackstone dam to be renovated is on dry bank, the project can be on land. The dredging trench has small

earthwork usually, and is applicable to manpower, just loading the spoil, paving the sand-cushion and

jackstone; while in the area of water it is applicable to wadding sinking, jack-pillow and jackstone. The

last step is to repair the surface of slope structure construction by manpower.

2. 8.2.3 Bank Revetment project

On the basis of site investigations, most banks along the whole sea-route have been revetted, and the

banks with no revetment mainly include Wushi Power Plant- Wushinan, Lunzhou-Qixinggang,

Hululing-Xiaoshinan (Feilaixia-Qiangyuan Bridge section), which is 15km long on both sides with

27


earthwork of 30k cube meters. The main working procedure of bank revetment is: repairing shoreline-jackstone - stonework - hardening the surface of revetment - forestation. Practically it ise.iirth,urk.-digging first, then slope repairing, followed by filter bed paving, and finally stonework on thesurface of revetment. The bank revetment will maintain the bank with original gradient, and slopeproject includes mainly clearing surface shrubbery and leveling up rough slopes with earthwork, so thewaste earthwork can be refilled and spoil can be reduced greatly. The project is mainly done in lowwater or dry beach, seldom in water. According to the ;haille of the slope, the project can be finished bymanpower or mechanism.

2.8.3 Process of environmental impact identification and selection

2.8.3.1 Analysis of influencing factors during waterway regulation process

(I) During waterway regulation working process, '.1t-n 'i:: may be caused to suspend,influencing the water quality and the ecological environment in the water area of the construction site;dredging and structures may occupy certain water area, damage the habitat of benthos and will influencethe habitat of aquatic life and fish, but the impacts on the species, community and quantity of organismswill be little. The ecological environment in the water area within the construction site will be restored toits normal state on the completion of waterway regulation.

(2) Such construction transporter as the stone-dumper ships, transport ships etc. Will produceoil-contained wastewater, life-sewage, solid waste and other wastes, influencing the water environmentin some degree.

(3) As the waterway regulation work is launched in a comprehensive range, the traveling of thoseconstruction transporters will influence the normal traffic of vessels, and maybe constitute hiddendangers or even accidents.

(4) Construction work noises will influence the acoustical environment along the banks

(5) Backfilling work will influence the ecological environment on the land areas on the banks.

2.8.3.2 Environment influenc analysis on dredging work

(1) Operating dredge boats will stir riverbed mud up to suspend, influencing the water environment andthe habitat of benthos.

(2) Rising the buckets to put mud into a towboat may cause splash or leak of some mud, thus toinfluence the underwater environment.

(3) Leakage or spillage of sediment may arise during transporting work, thus to bring suspendedsubstances into the water.

(4) Dredge boats and muck barges may produce vessel wastes.

2.8.3.3 Environment influencing analysis on construction site

(l)The temporary prefabrication site of the construction occupies certain land area, thus harming thelocal ecological environment to a small degree.

(2) Transportation and storage operations of sands and stone materials may lead to the occurrence ofdust.

(3) Concrete mixers, cranes and other construction machines as well as transporting vehicles wouldmake noise.

(4) Construction personnel will produce life-sewage and garbage during their working process.

To sum up, the influencing factors on the environment in the construction process of this project areillustrated in i-iLIrue 2--4.

species ) accounting for 6.9% respectively, Chrysophycophyla (I specie) and Cryptophycophyta (Ispecies) accounting for 3.4% respectively.

For this session's investigation result, 63 families (genus) were found at six sampling spots (B l-B6). 63families (genus) belonging to phytoplankton were found including 13 kinds of Cyanophyta, 27 kinds ofChlorophyta, 19 kinds of Bacillariophyta, I kind of Pyrrophycophyta, I kind of Euglenophycophyta, Ikind of xanthophyta, and I kind of Chrysophycophyta. Cell density of phytoplankton was7.5-52.2* 1 04cells/L.

Principally, Bacillariophyta were the dominant species at the six sampling spots (BI-B6) with a celldensity of 4.05-44.3*lO4cells/L. The density of Cyanophyta and Chlorophyta were 1.05-12.35*10 4celLsfL and0.6-2.77*10 4cells/L respectively. Cell density of phytoplankton at Chetouzhou (B2) , Baisha Town (B3),Liangshuijing (B4), Zhouxin Town (B6) were far lower than that of the phytoplankton at Mengzhou DamReservoir (B 1) and Baihexun (B5). At the same time, cell density of Cyanophyta at B I (accounting for 25.6% of totalcell count) and B5 (accounting for 13.7% of total cell count) were also higher than thatof Cynophytafoundat otherspots. On the contrary, species and MGL-INDEX of phytoplankton at reaches of B I and B5 were far less than that ofones at Baisha Town, Chetouzhou, Liangshuijing and Zhouxin Town located at the main sueam of Beijiang River.Basically, phytoplankton at all sampling spots of Beijiang River belongs to Bacillariophyta Cryptophyza andCyanophyta.

b) Distribution of species with seasonal changes.

Data from survey during years 2000-2001 indicated that Euglenphytao and Chlorophyta were rare onesand others could be found at all reaches of Beijing. Bacillariophycophyta mainly falls into Melosiragranulata, Cyclotella meneghiniana and Fragilaria Lyngby, Chlorophyta mainly falls into Staurastrwngracile, Chlamydomonas sp. and Scenedesmus quadricauda (dominant ones), and Cyanophytacommonly falls into Phormidium sp. and Gloeocapsa sp.

meanwhile, result of this session's survey indicated that Bacillariophyta mainly comprise Melosiragranulata and Navicula sp., Chlorophyta are mainly composed of Staurastrum gracile,Chiamydomonas sp. and Scenedesmus quadricauda, Phormidium sp. and Gloeocapsa sp. arecommonly found in Cyanophyta.

Data from survey during years 2000-2001 indicated that the distribution frequency of phycophytadiffers in different seasons, according to a review of species appeared in lower and high water period.For example, Cyanophyla and Bacillariophycophyta can be frequently found in both lower or highwater period, so, they are perennial ones. While most kinds of Chlorophyta appear in high water period,and some kinds of Chrysophyta and Pyrrophycophyta only appear in lower water period. Phycophytaof other families (genus) rarely appear. This can be evidenced by this session's result.

c) Seasonal changes in quantity.

The most striking hallmark of phycophyta in quantity is their perennial stability,their quality is verystable at a low level without obvious fluctuation. Maximum of quantity appears at Feilaixia Gorge Dam(A3) valuing 0.56X 106 cells/L during high water period. Within the rest of the year, the quantity ofphycophyta changes little valuing 0.39 X 106 cells/L in average. Cyanophyta, Chlorophyta andBacillariophyta are the 3 predominant phycophyta, concentration degrees of Cyanophyta andChlorophyta are far higher in high water period than in lowwater period due to their thermophilicnature, while Bacillariophycophyta and Pyrrophycophyta can tolerate a relatively low watertemperature.

(2) Zooplankton

a) Categories and distribution.

The survey during years 2000 - 2001 indicated that there were totally 51 categories of zooplankton in the 3 spots of

Feilaixia Reservoir Area. Among them, protozoa presents 5 species falling into 4 genera, Rotatoria accounts for 31

species falling into 18 genera, mainly made up of Keratella cochlearis, Keratella valga, Ascomorpha ecaudis and

34


Potwyrthra trigla Most of the zooplaw*tons are those of extensively distributed planktons. Categories and quantity, as

well as Shannon-Weiner Index ofzooplan4ion vary much among the spots. Shengping Hengshi Spot (A2) harbors ispoor, while other spots like Al and A3 harbor are richer in the quantity and categories of them. Cladocera accountsfor 10 species of 7 genera. Those ones frequently found in all spots, extensively distributed, and with very goodadaptability,are Diaphanosoma brachyurwn, Bosmina longiustrn,and some Ceriodaphnia comuwa, which usuallylive in clear water. Copepoda occupies 7 species falling into 6 genera, mainly Cyclopoida and diaptomus. Most ofthem are extensively distributed categories, such as Mesocjcops leuckari, Thermoc)clops taihokuensis and

Phyllodiaptomus tunguidus, etc. &hmackeria inopinus can only be found during high water period.

b) Changes in quantity.

The survey during years 2000-2001 showed that during high water period, the density of zooplakton at Damiaoxia(A3), Shengping - Hengshi (A2)and the Dam (A I)were 27.95ind/L, 4.1 5ind/L and 363ind/L respectively, while

during lower water period, their density werelO.25ind/L, 13.75ind/L, and 11.75ind/L respectively.Quantities of different species of Zoopkznkton taper as Rotatoria, nauplius, Cladocera, Copepoda juvenile,

Copepoda adult, and protozan. Protozon is the least and only appears at Damiaoxia (A3) either in high or lowwaterperiod. Quantity of Rotatoria becomes higher during high water period, and has a greater fluctuation among the spotsduring high water period than during the low water period. Distribution of Copepoda grub is similar with that of

Rotatoria As for Cladocera, during high water period, their quantity in the Dam (B I) spot is much higher than that inother spots, but during low water period quantity at the Dam (B 1) decreases to zero. The quantity of Copepoda adult

during low water period is much larger than that in high water period, and quantities among the spots fluctuate with a

large range.

Cell concentration in 6 surveyed spots (B3-B6) in this session is 1.96-21.8 ind/L, and the concentrations ofRotatoria, Cladocera, and Copepoda are 0.42-7.76 ind/L, 0.22-6.64 ind/L and 0.70-7.36 ind/L respectively.Viewed from the diversity index of Rotatoria, Feilaixia Reservoir's (Al )RotatoriaShannon-Weiner Index was lowerthan that in the other 5 spots., Among the 6 spots, Rotatoria Shannon-Weiner Index of upper reaches is higher thanthat of lower reaches, while category distribution of Cladocera and Copepoda differslittle. Categories and quantitiesof them were also little. Bosmina longirostris and Diaphanosoma brach,auwn were the dominant ones in CladoceraAs for Copepoda, Heliodiaptomusfaixus and Tropocyclopsjerseyensia were the dominant ones in Zhouxin (B6),while Phyllodiaptomus tunguidus and Mesocyclops leuckarti are the dominant ones in other spots.

In general, velocity of flow in Beijiang River is relatively fast and Cell density of zooplankton is low.Copepoda is the dominant group in biomass, cell concentration in the lower reaches is relatively higherthan that in the upper reaches, and cell concentration in Zhouxin - Qixinggang (B6 )is much higher thanthat of in other 5 spots.

(3) Bottom Fauna

a) Categories.

Bottom fauna falls into 85 categories in Beijiang River. Annelida falls into 13 species of 10 genera in 9 farmilies,Mollusca falls into 29 species of 21 genera in 10 families, Crustacea Nlls into 2 species of 2 genera in 2 families,Insecta falls into 41 species of 39 genera in 27 families, as seen in Table 3-1-1. Dominant ones are Fridericia bulbosa,

Lipangopaludina chinensis, cjpougapoludina cathayensis, Bellamya quadrata,, Rivularaauriecata Semisvlcospjrabaccata, Semisvlcospira mandadia, Limnopema lacastris, Corbiculaflwninea and so on.. Ipangopaludina chinensis,

Semisvlcospjra baccata, Corbiculafluninea, Semisvlcospira mandarina are the most extensively distributed andwith the largest quantities. The species of aquatic insects stand at the No. I position accounting for 53.09% of totalspecies, Mollusca accounts for 27.630/o, Oligochaeta accounts for 14.470, shrimp of Crustacea accounts for 2.6%,and Platyhelminthes accounts for 1.32%.

b)Individual number and biomass

The largest annual average biomass is at the upper reaches of Beijiang River near Shaoguan, amountingto 672.9g/m2-864.25g/m2 , while the least biomassis only 0.91 g/m2. Individual number ranges at3ind/m2'6.478ind/m 2 . Rhythm of seasonal changes also assembles the change of biomass. The biomassin low water period is higher than that in high water period. The average output of bottom fauna inrecent two years in the main stream of Beijiang River is 1429ind/m2 , and biomass is 288.726gjm2 .Percentages of biomass among the total amount of bottom fauna are as following: Annelida accounts for0.29%, Mollusca accounts for 98.78%, and Aquatic Insect account for 0.93%.

c) Results of Complementary Survey.

Results of complementary survey at 6 spots (1B l-B6) of this session, indicated that survived bottomfauna are scarce due to the cobble -sand bottom of the middle reaches of Beijiang River, letting alonemany years' withdrawal of sand and stone from the river bed. Survived bottom fauna are mainlyMollusca (9 kinds), Oligochaeta (I kind) and Insect grub (4 kinds only), The density of bottom fauna inthe middle reaches is 3.75-15.5ind/dm2 and biomass is 0.525-5.215gdm 2. Liangshuijing (B4) and

Zhouxin-Qixinggang (B6) have relatively higher biomass of bottom fauna. Corbicula fluminea ofMollusca is the dominant species in all spots.

(4) Aquatic Vascular Plant

a) Category.

Aquatic vascular plant in Beijiang River falls into 12 species of 8 genem in 6 families. The reaches with the densest

aquatic vascular plant (9 species) is near Shaoguan , and the thinnest is at the lower reaches totaling 5 species.

Percentages of certain species among total biomass (calculated by wet weight) are: Hydflla varticillata(Lf.) Royl,

the dorninant one, accounts for 38.5%, Vallisneria spiralis L. accounts for 37.4%/O, and Najas marina L. accounts for

9.72%. The most extensively distributed are Vallisneria spiralis L., Hydfllla varticillata(Lf) Royl and Polamogelon

malainus Afiq. See Table 3-1-2.

b) Main species distribution

Along banks of Beijiang River, except for those torrential areas, 5-6 meters wide belt of aquatic vascular plant can be

found and Hydfllla varticillata (Lf) Royl, Vallisneria spiralis L. and Potamogeton malainus Miq. are the dominant

ones.Table 3-1-2 Category of Aquatic Vascular Plant

3.1.1.3 Rare and important species, and critical habitats

According to the analysis based the above-mentioned surveys, all the phytoplankton, zDoplankton and aquatic

vascular plants in the North River belong to the usual catagories. There are no rare and important species, and critical

habitats.

3.1.2 Fishes

3.1.2.lMethods of surveyThe survey on the fish species are mainly conducted with the following methods: 1) Collecting of historical

infonmation;.2)Field survey by the fishery expert, Professor Chen Xianglin with South China Normal University and

the investigation team; 3)Consultation to the local fisherfolk and fishery experts from the fish-managing authorities.

The survey was contducted in May of 2002, and lasts one month. The investigation spots are the Qujiang reach,

Qingyuan reach and Yingde reach located in the mniddle section of the North River. Showed Fig.3-1-1(page 36-37)

3.1.2.2 The Result of theSurvey

For the result of this survey, please refer to Table 3-1-3 (All the fish names were checked on www.fishbase.om). The

results indicated that fish found in this survey belong to 44 kinds in total. Among them, the investigation team has

captured fishes of 16 species. Expect one rare speies named Angullia, the rest 15 species are the common economy

fishes.3.1.2.3 The Analysis of the Survey

A) Habits and characteristics of fish in Beijiang-River

The features of natural environment greatly affect the distribution of fish settling down in Beijiang River. Those fish

living in the upper reaches of Beijiang mostly are fishes accustomed to torrent and bottom life, or rocky caves. While

in the middle and lower reaches fishes accustomed to middle or upper layer of water above the riverbed are

frequently found. Fishes living in Beijiang River have basically reflected the general picture of Pearl River water

system, but fishes in Beijiang River differs in some certain degree from fishes in the other rivers of Pearl River water

system, and differs considerably from fishes living in PearlRiver delta. Compared with fishes in the neighboring areas,

fishes in Beijiang River adopt the most similarity to fishes living in Guangxi, which is a place to the west of Beijiang

but have the same latitude with Beijiang, and adopt the superior similarity to fishes living in Hunan, which is a place

to the northwest of Beijiang. Similarities between fishes in Beijiang and Hainan Island lie in the level of genera, and

they differ considerably from each other at level of species.

B) The reducing of output of fish in the North River

Some fishery information shows that the output of fish in the North River is reducing year by year. Thefollowing two reasons caused the gradual reduction of the output of fish. The first is the uncontrolledfishing in the river along the years. During the past years, many local residents make a living mainly byfishing, so they have directly caused the reduction of the fishes. The second is the ignorance of thefishes' living environment from 1960s tol980s. From 1960s to 1980s, China is still at the stage ofproduction development. In order to develop the power industry, so as to improve the industrial andagricultural conditions and people's living standard, dams were constructed along the river, so theyinterdicted the passing of fishes and caused the reduction of the output of fish.

3.1.2.4 Rare and important species, and critical habitats

It is indicated that the rare and important species in the middle reaches and the nearb branches aremainly composed of Macrura reeveii, Angullia and Siniperca kneri. Belonging to the anadromouscatagories, most of them habitate at the estuary of the North River, and only a few of them come to livein the Qingyuan reach. Macrura reevei spawns from February to May and Siniperca kner spawns fromApril to June. During the spawning season, when the water temperature is above 19 degrees centigarde,the fishes begin to spawn at the river conner, and usually at night.

According to the historical record. the spawning spots of species mentioned above are sparsely

37

Environmental fmpact Assessment for North-River(Shaoguan-Qingyuan) Waterway Regulation Project

distributed all over the North River system. The four common economy fishes mainlv lives in theslowly-flowing branch rivers and come to flowing water of the main river to spawn and reproduce.

No fish-passing establishment was designed during the construction of the Feilaixia Dam, so the passingway of fishes was obstructed and it brings some influence to the reproduction of the fishes. Therefore,three no-fishing areas along the North River have been established by Qingyuan Municipal Governmentto preserve and proliferate the species according to the habitats of the fishes in the North Riverconcerning their food-capturing, spawning and so on. The location of them are: the water reach betweenthe new and old Qingyuan North River Highway Bridge, Feilaixia Reservoir and the 2km water reachesnear the Baishiyao Dam. (The location and explanation of them are cleared illustrated in Fig 3-1-2 andtabel 3-1-4.) Any fishing activity is forbidden in the above-mentioned areas. Moreover, somecompensation is charged from the constructed power stations according to their output of the electricity.This charge is used to buy and grow fries so as to ensure the sustainable development of the fishes in theNorth River. This is an important move to protect the fish species in the North River.

The last information shows that there is no construction spot in these three no-fishing areas. Among thethree no-fishing areas. two areas are in upriver about Ikm of proiect areas (includine No-fishing ofBaishiiiao Power Station and No-fishing of Feilaixia): another is in downriver about lkm of proiectareas (only No-fishing of Oingvuan Bridgzes), so the no-fishing areas will not be directly impacted by theproiect.

34.1.3.2 Results of SurveyResults from investigation on types of vegetation in areas of rectification reaches of Beijiang River indicate thatterrain and surface feature of middle reach of Beijiang River plays a key role in detemiining types and distribution ofvegetation along the river. Types of vegetation along the river are: terrain second growth, bushes - beach bamboogrove, bush- herbosa - bottom land forest - alluvial-plain artificial agricultural crops. See status quo of vegetation inthe Annex: Name of Plants (in ANYAIEXR), Color photos 1-6 (in page 50) and Fig.' 3-1-3a-d (in page 51-54).Preliminary prospecting and observation of all-line reaches have been conducted in this session. Observed parametersinclude tenrain and surface feature of banks, types of vegetation, major species of plants and human interference.

Quadrat investigation has been conducted at areas representing a variety of vegetation types. Consideringdiscrepancy of distribution of vegetationand combining faatures of this engineering, emphases of investigation wereplaced on vegetation coverage along rectification reaches and quany (in attempt), which will supply building stonefor this engineenng.(1) Status of Vegetation Cover along RiverbankVegetation along banks are mainly bamboo grove, bush-herbosa and farm-land vegetation. Some segments can alsosee plantation formed by eucalyptus and Chinese red pine. At banks and alluvial land, wet demanding grasspredominantly covers the land. Following is the details.I)Bamboo G1ye. Bamboo grove dominates land along the river and lay out along the river with a belt shape of30-50m wide (see color photol-4). Height, density and coverage degree are in discrepancy due to different soilconditions. They are generally lOl5m in height, and a few are 3-Sm tall. Bamboo grove at favorable soil conditionscan reach a height of 20m. In areas undergone investigation, bamboo grove at banks of Baisha Town of Beijiang isthe most flourishes, and their height can reach 20m and diameter of stem can reach lOcm, whose bank locates in lowand flat land with high groundwater level. Organization of bamboo groves are very simple, usually only an arborlayer formed by bamboo can be seen lacking bush layer, herbosa is scarce or null.

4) Farm ekl Farm field are mainly located within banks or tablelands. Most area of famn field is dry land.

Pnncipal crops are mulberny, com, sweet potato, groundnut, peanut, taro and beans. At Bainiao and LunzhoudaoIsland, there locate some small viUages, and around the villages are some farm field surrounding by frit trees asEuphoria longan, guava, banana, Clausena lansimwn and Chinese chestnut

5) Other Vegetation. In lands of banks near the river and alluvial islands (lands) that have undergone

investigation, there are some wet-demanding herbaceous plants, as well as some arbor trees (see Table3-1-12.3-1-13) . On higher sandy alluvial islands, shrub-herbaceous plants with distribution similar to

that on tableland or mountain ground are frequently seen. Some larger alluvial islands even have

planted forest, villages and farm field (e.g., Lunzhoudao Island). On an alluvial island (called the Snake

Island by the natives) situated at the engineering area of Baisha Town of Shaoguan City, there is

broad-leaved forest covering the island. Height of them is about 15-20m, and coverage rate is 50-80%.

Reckoned on the basis of a quadrat of 200 m2, arbor layer harbors 20 arbor treesof 6 species, with a

girth of 40-180cm, and the average girth is 60cm. Shrub layer is thin. Plant species include Vitex

negundo,Chinese alangium,Celtis sinensis and Triwnfelta bartramia. Coverage rate of herbaceousplants is 50-90%, and panicum psilopodiwn is the dominant one. Others are Sambucus chinensis,

Polygonum chinense and Alocasia rhizome.

(2) Vegetation in the QuarryChoice for Location of quarry supplying building stones for this engineering is pending, and it may be changed ondemand by the engineering. Investigations on candidate quarTy indicate that soil-vegetation covers of the candidatequanies are basically the same, aDl of them are of already being quanied. They are affluent for granite layers but thinvegetation cover, shrub-herbaceous plants are the dominant species. For instance, Longtoushan Quany, which locatesnear Baishiyao at middle-upper reach of Beijiang River, is a mountain slope, whose vegetation cover isshrub-herbaceous plant clusters Height of the vegetation cover is 2-5 meters with a coverage degree of 600/o-800/o.Dominant plants are V4tex negwido, Rhu chinensis, Mamosa sepa, Lagersmromia mcica, Mallotzs apeltaLespedeza cww=ata Ischaem'wn, Artemisia kandulaefolia. At Yuantan Town Quarry of Qingyuan City, which issituate at middle-lower reach of Beijiang, vegetation cover is mainly formed by thrush and herbaceous with litlecategories, coverage degree is 40(70 0/o.

Vegetation covers of other quany are simple. Thrush-herbaceous plant clusters predominantly settle down onmountain slope and thrush and herbaceous plants are the dominant ones. Some places harbor some arbor trees asChinese red pine and Rhus chinensis. Thrushes comprise VJtex negwudo, F7uggea veusc, Triunfetta bartramiaVubwmnu foniiae, Elaeagnus pungens, Sageretia theezans, Lagerstromia indica, Mallotus apelta, dominantherbaceous plants are MiscanLbur florz&duI, Lespedeza cwueata, Xanthiun sibiricum, Ischaemwn, Cynodondactylon, Paspalwn scrobicaukwm, Imperata cylindrica, Neyraudia montwan and Hwnulus scandens, etc.

34.1.3.3 Results of Vegetation CoverPreliminary prospecting and observation of all-line reaches have been conducted in this session. Observed parametersinclude terain and surface feature of banks, types of vegetation, major species of plants and human interference.Quadrat investigation has been conducted at areas representing a variety of vegetation types. Principal types ofvegetation are bamboo grove (Bambusa bzvifolia is the dominant one), thrush-herbaceous plant clusters, farm fieldvegetation, wet-demanding grassland, a little eucalyptus trees and thin trees of Chinese red pine. According to theway-based investigation, the above-mentioned major vegetation had undergone quadrat investigation. Totallyl500m2arbor quadra4 175 m2thrush quadrat and 15 m2 herbaceous quadrat were investigated. Recorded plants faDlinto 112 species in 41 families. For details, see plant bibliography. Organization and species of vegetation in thesurveyed areas are quite simple. They are mostly common species of second growth plants with little volume oftimber and biomass. The latter does not exceed IOOt/ha in general.

Human activities in the surveyed areas are intensive. Orgnization of vegetation there is simple. Bamboo grove andfew planted forests, thrush-herbaceous plant clusters and grassland are the dominant ones with little biomass valuing0.06-0.56kg/m2 , and the average coverage rate is 500/%. Biomass of planted forest is 80t/ha with an average coveragerate of 40-70%. The variety of plants is relatively simple. Those plants more tolerable to human interference andaccustomed to human-companion are more frequently found.

Quarries for building stone in surveyed areas are also characterized with simple makeup of vegetation due tohuman-interference factors. Plants more tolerable to human interference and accustomed to human-companion aremore frequently found. Statistics show that biomass of arbor layer in quarry of this area ranges at0.2072-4.0272kg/m 2, while thrush-herbaceous plant cluster layer ranges at 0. 1-0.45kg/m2.

Shannon-Wiener diversity index of thrush-herbaceous plant cluster and grassland in this area ranges at 02 1-0.30,and the value of planted forest ranges at 0 (purely forest) -1.98. Data from study on Dinghushan Natwe Reserveconducted in 1983 by Peng Shaolin, Chen Zhanghe, et al, indicate that the shannon-Wiener diversity index of arborlayer of mixed broadleaf-conifer forest is 1.96-2.86, and that of the evergreen broad-leaved forest in the Reserve is4.12-4.84. Therefore, we can see that biodiversity index of vegetation coverage in this area is very favorable, andhuman-interference is fierme.34.1.3.4 Rare and important species, and critical habitats

^il ' I't ' QUlxi i'1 cr\ \> ~\ itli 't;'i c.:'C .are and endangered plants in the surveyed areas have not beendiscovered. Bamboo grove is the most frequently found and the most extensively distributed type of vegetation alongthe river undergone survey. Bamboo grove near the river can play an important role in the protection of the banks, aswell as in serving the scenery purpose in south China. Bamboo grows to be lumber with high speed and therefore itharbors profitable potential and deserves conservation.

34.2 Investigation and evaluation of water environment quality

34.2.1 Investigation of actuality of water environment

The information of present water quality comes mainly from existing supervision and surveyinginfornation.

( ) Tune limit of informaion collectionThe information comes from the Environment Monitoring Stations of Shaoguang, Qingyuan and Yingdecities, and the information covers the situation of the period of recent 3 years (1999 - 2001) and fromJanuary to May 2002.

(2) Supervision and surveying sectionIn order to protect water environment.There are 15 routine water quality supervision and surveyingsections set up by GDEPB in total existing along the middle reaches of Beijiang River from Qingyuan toShaoguan, among which, five sections (1#--5#) are in Shaoguan, eight setions (6#-13#) are in Yingdeand two sections(14#-15#) are in Qingyuan. For the details please refer to Table 3-2-1 and Figure3-1-la,b. The above supervison sections are the ones that are under regular supervison. Accordinp to theresult of years of monitoring. the river width between the upper stream and the down stream of theconstruction section differs little, so does the water depth and some other water conditions. And thewater quality of the construction section and the regularlv monitored section is basically stable.Therefore. the existing information from monitoring can be adopted in the water quality analysis.

(4) monioredItemsThe items monitored by different stations and collected in different years are variedGenerally they arePH, Temperature, SS, Rigidity, DO, index of permanganate salt, BOD5, N0 2-N, NH3-N, VolatilizationHydroxybenzene, Cyanide, Cr+6 , Cadmium, Plumbum, Hydrargyrum, Arsenic, OIL and so on.

(5) Measures of analysis

Analysis shall be carried out according the Standards of Surface Water Environment (GB3838-2002)

(6) Measures of evaluating actualiy

Through comprehensive evaluation of the quality of the water collected from Beijiang River, as well asthe analysis of the indexes of SS, BOD5 and Ammonia Nitrogen from 6 sections which coverMengzhou Dam of Shaoguan city (2#) , Baisha (4#); Baxia of Yingde city (1 I#) , Shibeitang ( 12#):

Qixinggang of Qingyuan city (14#) and Qingyuan harbor (15#) .For the details of annually changing

status please see Histogram 3-2-j1 3-2-6

3.2.2 Analysis and evaluation of the actuality of water environment

According to the statistics of the water quality of 15 sections which were under monitoring from 1999 tothe May of 2002,

(1) There have already been two monitoring water sections in Section A of the project (the reach lyingbefore the Mengzhou dam of Shaoguan), in the reach before the Wujiang Bridge (I#) and Qujiangbridge (2#) of Shaoguan. The quality of the water which is under monitoring is below the nationalstandard of class III as refer to the quality of the surface water environment. And this shows that thewater quality of the upper river of Section A of the project is good.

(2)1n the reach between Section A to Section B, among the water quality indexes of 3 sections includingMengzhou dam (3#), Baisha (4#), Gao bridge (5#) from 1999-May 2002, except that the heavy metalCadmium exceeds the specified standards slightly, all the other supervised and surveyed indexes werebelow the standard of class III on the aspect of state surface water environment quality. This has shownthat in this river section, there is certain heavy metal pollution in this river section, which resulted fromthe sewage discharged from the enterprises on the upper reaches and the heavy metal content in thebackground of this area is rather high.

(3)ln the reach between Section C and Section D, there are six sections, that is Gao bridge of Yingde(6#) , Shakou (7#) , Xiangyang village (8#) , Dongguapu (9#) , Gaopotang (10#) and Baxia(1 1#) , the regular monitoring indexes of water quality from 1999 to May 2002 were below the

standard of class III as regard to the surface water environment quality and this represents the waterquality of this reach is good.

(4) In the reach of Section E (the reach between Feilai Canyon to Great Bridge of Qingyuan ) Theindexes of the quality of the water which is under monitoring from 1999 to May 2002 were below thenational standard of class III as refer to the quality of the surface water environment. And this showsthat the water quality of the reach is good.

But in the section (15#) of Qingyuan harbor, except Ammonia Nitrogen exceeds the specified standardsduring low water of 1999 (consistence at 0.502 mg/L, exceeding the specified standards by I time),heavy metal Plumbum exceeds the specified standards (consistence at 0.021mg/L, exceeding thespecified standards by.50%). While in 2000, heavy metal Plumbum exceeds the specified standards

during high water period (consistence at 0.015mg/L, exceeding the specified standards by 50%), duringlow water period heavy metal ldi14mi+mt exceeds the specified standards, (consistence at &.021mg/L,exceeding the specified standards by 105%), each routine index was below the standard of class HI onthe aspect of the surface water environment quality and this represents the water quality of this river isgood.

(5) According to the annual histogram of the change of water quality at each section such as SS, BOD5

57


and Ammonia Nitrogen, SS consistence during high water period is comparatively high; BOD5

consistence is comparatively high during low water period; and for Ammonia Nitrogen there is noobvious difference between low and high water periods. In general, there appeared an annually decliningtrend on the individual consistence of SS, BOD5 and Ammonia Nitrogen from 1999 to 2002.

3.2.3 Results of the research on the sensitive point of the water environment

According to the result of the research on the present water quality, the sensitive point of the waterquality includes:

1) Protection of Dinking Water Protection Areas. There are three drinking water protection areasalong the middle section of the North River, which locates at Qingyuan, Feilaixia Reservoir and Yingde,referring to Fig. IL4-'-4.According to the analysis of the project, only Qingyuan drinking waterprotection area which is within the project-may be impacted by the project. But Yingde drinkin', w%aterrontcctioin aredi is about Skiim do\k ntrcaiij of' pioiect site [). tbe iimpacted b\ the proiect ma% be less.

Therefore, mitigation measures should be taken to protect the water quality of the OingyQ1aii drinlkin-atcr protection zone-i..iuil\.[-L'.\p)liiiulioii in the tid'IC3--2.

2) Protection of Water Intakes

According to analysis of the materials of the latest project, ten pumping stations in the middle reach ofNorth River are in the section of the construction. For detailed information, please refer to table '.4-2-2and Ei- i4t 2-3. ,. Among the stations two are drinking water stations that is, WushiElectric Plant drinking water station and Qingyuan drinking water station, the others are all pumpingstations for irrigation. So priority should be given to protection of the water quality of the two drinkingwater stations.

3) Protective Measures

According to the identification of the sensitive point, while dredging up on the sensitive points, measuresshould be taken to reducing the pollution of the water quality, and ensure that the water quality won't beaffected by the construction.

3 Residual Contaminant Fish Body Burdens

(1) Items supervised and surveyed

The items supervised and surveyed include 6 items: Cadmium, lead, Arsenic, mercury, DDT and

Petroleum.(2) Time limit of information collecting:

The information needed come from the report of Influences to Heavy Metal Pollution within

Water Conservancy Area in Beijiang Feilaixia Irrigated Project worked out by Office of Pearl

River Resources Protection (Year 1986), and the information collected by Yingde Environmental

Supervision and Surveying Station in 1995. The result is shown in Table 31j.

(3) Supplement of surveying

In order to meet -the requirement of the World Bank, supplemented sampling in the river sections

of Shaoguan, Yingde and Qingyuan has been carried out one time. The result is shown in Table

3-5-2. For the information of the points to supervise the sample of different fishes, please refer to

figure 3-1-1.(4) Analysis of result

Through the analysis of the existing materials and the supervising result , we found out that

residual poison within the fish body taken from the middle reaches of Beijiang River is rather low,

especially in the 90s' thanks to the protection carried out by Guangdong Provincial Government

and local government, there was a declining trend of the content of heavy metal in fish body And

in 1983, after the State Council issued a prohibition order to use DDT and BHC, which harm the

health of human and livestock greatly, DDT had never been traced any more within the fish in

Environmental Impact Assessmentfor North.River(Shaoguan-Qingyuan) Waterway Regulation Project

4-.2.1.lPredicted Influences of Dredging Construction SS on the Water Quality

in the Lower Reaches of Rivers

(1) Mode of Prediction

Two-dimensional steady-state mixed subsiding mode for plain and straight river sectionsThe

two-dimensional convection and spread equation for silt motion at the unilateral river sections:

dc -(My c) + (C -C = S.

In the equation, "x, y" stand for the longitudinal and lateral coordinates respectively (im); "u"

is the average current velocity of water at the river sections, where pollutants are obsorbed

(m/s); C is the thickness of the suspended sediments(mg/L); My is the lateral mixing coefficient

(m2/s), which shall be sampled according to the recommended formula in Environmental

PollutionAssessment Standards for Inland Navigation Construction Projects (JTJ227-2001 )

formulated by the Ministry of Communications; SLB iS the input speed of suspended sediments

(g/s): - is the subsiding velocity of suspended sediments (m/s), Cb is the carrying sand

capacity of currents.lt can be calculated according to the following formulas of experience

(Literature Movement Mechanics of Silt, by Qian Ning, etc., Published by Science Publishing

House in 1991) .(2) Identification of Various Parameters of the ModeThe choosing of the hydrological data of the currents should be based on the designed and

road-tested parameters in accordance with the Feasible Research Report on the River-Routes

Treating Projects of the Middle Reaches of the Beijiang River (River Routes Between Shaoguan

and Qingyuan).The landform of the riverway shall be calculated according to the river-routes map with a scale of

1:2000.And all the other parameters shall be identified on the basis of the requirements of the Rules and

the Regulation, which have been mentioned above.

(3) Assessment Standards of the Influence Imposed on the Water Environment

The Standards of the Water Quality in the Fishery Industry (GB 11607 89) shall be adopted.

(4) Prediction on the Seriousness of the Pollution caused by SS Pollution Sources

The analysis on the possibilities of occurring SS in all construction sites has been delivered in the

previous projects analyzing report. Now the SS emission quantity will be further detailed in the

following part.(1) According to the data provided by the feasible report of the project, the basic condition of the

riverbed under construction of the Beijiang River are: from the upper reaches going to the lower

reaches, the main sediments of the riverway between Mengzhou Dam of Shaoguan and Wushinan

and that between Baishiyao Dam and Daluodu are sand and scree. The diameter of the sand varies

between 18.2mm and 25.5mm. There are few silts and suspending substances. Generally speaking,

the speed of the clamshell silt dredge boat can reach 20-30m3/h. When Im3silt is dredged, 20kg

SS suspending substances will be produced again if hermetical clamshell silt dredge is used. And

the usage of open clamshell silt dredge leads to the reproducing of 25kg SS suspending

substances.(2) The riverbed substances of the riverway between Qingyuan Feilai Canyon Dam and Qingyuan

Bridge are mainly smaller sand, whose diameters are 0.3-0.81mm. Because this is regarded as the

zero emission zone of pollutants in Qingyuan, there are fewer silts and organic substances, and the

74


sand on the riverbed here are cleaner and whiter. The main dredging machine is the suctional silt

dredge boat with a speed of 80-120m3/h. This kind of dredge will produce suspending substances

of about 5kg/m3

(3) According to the relevant design documents of the project, the quantity of SS suspending

substances will reduce by about 40% if certain measures have been adopted during the period of

dredging, such as il . in order to slow down the process of construction. Based on the

previous analysis, it can be estimated that the SS pollution source has a strong capacity of causing

pollution. The results can be seen in the following table 4*-2-1+

(5)Results Foreseen and Assessments

Table 4-2-2and 4-2-3have illustrated the predicted results of the dredging work's influence on.the

water quality at the lower reaches of the river when using the previously mentioned mode .

Due to the small dredging workload of this project, the major composition of the riverbed

substances, that is scree and sand with low quantity of silt, and comparably favorable water

condition of the middle reaches of the Beijiang River, the quantity of SS produced is very small.

Therefore, the results have shown that:

(a) If no effective measures have been taken to release the production of SS, the preset assessment

standards of SS density lOOm within the dredging site at the lower reaches of the river (lOmg/L

according to the water quality standards in the fishery industry) can be basically reached, but at

.the riverway between Mengzhou Dam and Qingyuan, especially near the water draining point of

the Qingyuan Waterworks, the SS density outruns the preset standards ( 1.748mg/L larger). The

water draining points, which are 300 or more than 300 meters away is less seriously affected. And

when the dredging site is nearer the upstream of the river, the impact on the water draining points

will become consequently smaller.

(b) If protective measures, such as silt curtain, or measures of releasing the dredging workload

have been taken, SS density of the water 50m near the dredge site can be basically controlled

within the preset standards, and therefore its influence on the water quality I OOm farther away the

downstream will be smaller.

(c)According the analysisi to the project, the dredging work's impact on the water quality at the

lower reaches of the river will be in short-term; it would be end when the constuction period

finished.

:6) The monitoring results from other projects

In its document titled "EIA of the Third Phase Beijiang Bridge Construction Work in Qingyuan"

(which has been examined by Guangdong Provincial Environmental Protection Bureau in 2001),

and the document titled "EIA in the Consolidation Project of the Bei-jiang Riverbank" (which has

been examined by the SEPA in 2001), South China Environmental Science Institute has once

evaluated the factors which have an influential effect on environment and observed the riverbed

dredging process of the clamshell dredger (2.5-8.0 cubic meters per bucket) and suctional dredger

(80-120 cubic meters per hour) along the regulation line. The observation results are listed in

Table 4-2-4. At lower river reaches, during mud dredging operations if no protective measures

have been taken, suspending mud and sand are normally settling out completelylOOm-300m near

the dredging site; the quality of water about 400-meter near the dredging site is basically not

unusual, and the water at the upper river reaches is clear. Furthermore, there is very few

suspending substances brought forth by dredging waste spillage or leakage, which is ultimately

discharged in the spurs-fields.

77


Therefore, one can safely concluded that the predicted results are fundamentally the same with

that of the on-site observation of the past sand dredging work conducted by the commercial

dredger at the middle reaches of the Beijiang River. To sum up, although the suspending

substances producing dredging construction does have unfavorable impact on the quality of the

water about 100m around the construction site, this influence is generally acceptable here, and its

influence on the quality of water near the downstream draining points of waterworks and fishing

grounds are also acceptable. However, because part of the dredging site between Feilai Canyon

Dam and Qingyuan Bridge is located within the water source protection area of Qingyuan, in

order to ensure that the dredging SS will not affect the water quality, no on-site dredge can be

done neither without the approval of the relative local administrations and departments nor before

effective pollution prevention measures have been taken, for example the usage of Silt-Proof

Curtain or measures to slow down the process of dredging construction.

45.2-.1.2 Analysis of the influence of waste water of the dredger on the

downstream water quality

According to the analysis of the project, the amount of grease wastewater coming from the dredge

boat is 0.7t/d. The dredger is usually equipped with a separator of oil and water. After being

treated by the separator of oil and water, the discharged oil density of the grease wastewater in the

engine rooms of the ships is below 1 5mgfL, and the amount of oil discharged to the environment

is 10.5g/d. The wastewater will be discharged into broad water area only when the oil has been

separated from water. According to some similar experience, under this situation the wastewater of

the dredge boat usually has light impact on the environment, which here mainly refers to the water

in the river.

4-.21.1.32 Analysis of the impact of the sewage water

Sewage water is produced by two groups of people: the working personnel on the construction site

on land, and the working personnel on river. The per capita sewage water produced by these

working personnel is about 60g COD. Each vessel is furnished with 8 persons. Then each

construction point discharges 0.48 kg per day on average (COD concentration at 200mg/L). If 50

construction workers are employed, then the COD domestic sewage produced is about 3.0kg/day.

As what has been planned by the construction contractor, most of these working personnel are to

be arranged to live in the rented houses in towns and villages near the quays along the regulation

line, in order to cut down the quantity of the sewage water discharged directly into the river.

Therefore, domestic sewage will not constitute a major influential factor on water quality.

4.2.1.4512 Analysis of the impact of Solid waste in daily life

Solid waste means primarily the garbage chucked away by construction workers. Suppose that

every worker -will cause 1.0 kg solid waste per day on average, and if there are 80 workers, then

on each working day there will occur 80 kg solid waste. This project will adopted relevant

prevetion measures, such as gleaning solid wastes as to alleviate its influences on environment.

According the analysisi above to the proiect. the construction period impact on the water quality at

the downstream reaches of the river will be in short-term: it would be end after the constuction

period finished. Thev may recover in a certain period after the construction ends.

4._-2+.2.2 Prediction of Ship FlowThe number of ships will increase, but not too much, and the tonnage of ships shall be limitedwithin 300 tons when the guarantee rate is 95% because the channel is wider and deeper after the

completion of the channel renovation project. It will reach 10- 30% from 2005 to 2030.

On the other hand, the types of ships in the channel will be adjusted in a certain level. Accordingto the predicted results of goods transportation in the feasible project, certain change of ship type

also has occurred, including the increase in the number of ships with containers for goods and also

that of bulk freighters. There will be no large change in the number of passenger ships and other

types of ships except for possible decrease. Thus it can be seen that the container transport and

ships with large tonnage are the mainstream of development while the number of passenger ships

and other small ships will reduce year by year. This phenomenon is just the same with the recent

development of water transport.

%4.24-.2.3 Category of Discharging Pollutants from Ships and the Treatment

l 4pH4 4il '(, i H4. I the discharged pollutants from ships in Beijiangwill include wastewater with oil,

daily sewage and garbages. It is predicted that the amount of discharged pollutants from ships will

reduce because of the stricter navigation standards and the control of proportion of ship types. The

reason mainly lies in that large ships, such as container ships, have pollutants treating and

collecting facilities of oil sewage anddaily sewage and garbages. The reduction of numbers of

passenger ships and small ships will cause the possibility of reduction of discharging pollutants.

Thus, discharging pollutants will be reduced by a large margin.

2._+.2.4 Analysis of Influence Caused by Pollutants from Ships

a) Influence on water qualityThe water quality of the whole midstream of Beijiang River is comparatively better than that of

other rivers in Guangdong Province. Along the bank ofthe Beijiang River, there are many water

draining mouths of main waterworks, The target of water quality control is Grade 11-111 at the

river section between Yingde and Qingyuan, in which there are the water resource protection areasof Yingde City and Qingyuan City. If the wastewater and daily sewage with oil without any

treatment are directly discharged into the river, not only the water in the river channel will be

polluted, but the water quality in the said protection areas will also be affected. Especially in the

channel of Qingyuan City, every year the pollution of water caused by the pollutants discharged

from stranded ships is serious.b) Influence in other aspectsThe garbage poured into the river from ships may pollute the water and affect the visual scenery of

the river if the garbage is floating on the water. That will not only damage the conditions of the

river and also cause diseases. Some of the garbage with oil will consume the oxygen in the water,

which will threat fish, and let out undesirable smell. The garbage deposited in the water will

change the natural living conditions of hygrophilous animals and plants, and even cause the

metastasis or disappearance of certain living things. On the other hand, the garbage with less

density may be drifting about or sending under the water and accumulating at water area with -lesshydrodynamic conditions, or even flushed to the beach, in which case it will have a hidden

adverse impact on the environment of the beach.c) Management of ships

79


As for the future management of ships and for the purpose of reduction and externination of the

resource of pollutants, the treating equipments of pollutants on the ships shall be installed. The

pollutants will also be centralized and collected at beach. Every effort will be taken to reach the

standard of discharging pollutants after treatment from ships in order to reduce the pollution of

environment as much as possible. Meanwhile, law on ships control in the channel must be

implemented strictly. This will reduce the pollutants from ships and therefore reduce their effect

on the water quality in the river channel and thus guarantee the favorable environment of the

riverway.

4.35.2 Analysis of Impacts on Ecological Environment

4.3.15. 24 Content of Analysis of Impacts on Ecological Environment

The analysis aims at the improvement of the construction method of the project concerning

its impact on ecological environment within the analyses range, and will be carried out according

to the above-mentioned research result. The analyses method is analogy based on collected

information. The content of evaluation includes:a) Analysis of impact of the project on aquatic system of ecology;

b) Analysis of impact of the project on vegetative system of ecology.

4.3.245.32.2 Analysis of impact of the project on aquatic system of ecology

4.3.2.145.32.2.1 Analysis of the impact of construction on fish

Based on the result drawn from the public consultation, the latest project feasibility report has

taken a further step in improving the construction method. During the project, there is no

construction site in the three no-fishing areas.7 Therefore, this project will bring no direct impact

to the fish habitat, though some indirect impacts are inevitable during the construction.-Thev may

recover in a certain period after the construction ends. They are showed as followirng:

According to the investigation of the fish resource, the migratory fish in Beijiang River are

mainly composed of Macrura reevesii, Angullia and Siniperca kneri.

Macrura reevesii belongs to the migratory fish. Most of them live in Sanyi at the mouth of

the North River, and a few wander at the upstream to Qingyuan. The spawning season of them is

from February to May.

Siniperca kner, the spawning season is from April to June, and in the spawning season,, the

fish usually spawn at night when the water temperature is above 19 C, and often at the rushing

bay of the river.

Because there are no facilities for the fish to pass the construction of Feilaixia Complex, the

migratory routeway of fish is cut, and the reproduction of the migratory fish will be impacted in

some degree.

According to the investigation, the fish in the North River and its branches are mainly

composed of Semilabeo notabilic and four home fish. The spawning sites of Semilebeo notabilic

peters are distributed in different parts of the river; the four home fish inhabit the riverside, river

bay, and in the river branches or small rivers, but they will return to the river forspawning and

reproduction.

According to the above-mentioned characteristics of fish inhabitation, the dredging and

retaining of the project will have some indirect impact on the migration, moving and feeding of

the fishes. Therefore, the construction timeing will be selected to avoid timing of the fishes'

80


spawning season, and some measures such as the installation of uii!'.ri"u should be taken to

prevent the impact of the sediment on fishes.

4.3.2.24..-:t'.'.'Analysis of the impact of construction on other creatures who

used to bait in the river

The construction will cause turbidity of water body, thus to influence the photosynthesis of

hygrophilous plants directly or indirectly and cause the reduction of generated oxygen in water

body. But this only occurs in a small area of water body and will not generate great impact on the

whole water body. And the hygrophilous creatures have better adaptability. They may recover in a

certain period after the construction ends.

The construction will cause the water body to be muddy, and its iLr.inn;mrtmc, 1o t 1' will be lower.

This will influence the photosynthesis of hygrophilous phytoplankton. More over, it may increase

the percentage of diatom among the hygrophilous phytoplankton, which may cause certain

changes to the population of hygrophilous phytoplankton.

For the pelagian and benthos, if the content of silt in the water is large, the efficiency of filter

feeder may be reduced, the community structure of pelagian and benthos will be subsequently

changed, and the density of population will be reduced. It can be seen from the project analysis

and the result of water quality prediction that this kind of impact is slight.

The greatest impact of this project to hygrophilous ecological environment is that it damages the

living conditions of benthos. According to the calculation in the result of project analysis, the

sediment and dredging work in the project (including digging and filling) will damage about

1450000 m2 of the habitat of benthos in the river; more than 10 kinds of benthos will be affected

directly or indirectly. The quantity of affected biomass for per square meter is 52.5-521.5 g.

According to the investigation on water ecological status, the species of plankton and benthos in

the North River all belong to the common ones, and no rare and important species exist. They

have good resistance against factitious interference and are good at reproduction, so the project

will not have direct impact on the fish species. n . i. ,! \ i>. .' :1. ',:i

______ l_________ However, in order to protect the water ecological environment, some measures

should be taken to control and narrow the impact scope, and to reduce the impact on the bait

creatures. Such measures include the installation of mud-prevention screen, reining up the

intensity of dredging work and so on.

4.3.3-.'. Analysis of the Impact of Construction on Vegetation

4.3. 1 .`.3.1 Impact on Biomass

In these areas, the plant kinds are simple Most of them are the accompanying plants of human or

the plants with the characteristics of anti-interference.

Concerning the project itself, the revetment project damages some boskage and bamboo grove.

Thus the project itself has only a little impact on plants. But the commercial stone pits supplying

stone materials for the project have relative greater impact on the biomass loss of vegetation on

the ground. The estimated result of biomass loss in these areas is showed in Table - .

The biomass losses caused by stone pits are about 805 tons. The biomass of vegetation damaged

by revetment project is relatively less, i.e. the quantity is no more than 5.6 tons (calculated as

boskage of 10000 M2 ). But it is worth mentioning that the bamboo groves along the Beijiang River

are the most common type of vegetation, distributed most extensively in these areas. They are

important sceneries of rivers and lakes in Southern region and have important functions in bank

protection. Bamboos grow very fast, and have considerable economic value. They should be

81


protected in every effort. After completion of the projects, the bamboo groves will be planted on

the banks and beaches where the underground water level is higher.

4.3.3.2 Vegetation Protection and Recovery

According to the above analysis of impacts, some good work should be done in recovering the

vegetation after the revetment, such as planting grassland and Bambusa brevifolia(zkfi) along the

river bank and add vegetation in the commercial stone pit. With experience learned from other

project in Guangdong Province, the project team propose to plant Acacia confusa (0.5A4), pine

tree, shrub and other vanguard vegetation species, since they can grow easily and recover the

vegetation in the stone pit gradually.

4.453 Evaluation of the Impact of Dredging Wastes on Ecology

4.4.134Evaluation of the Harm of Dredging Wastes to Ecology

According to the survey results, at the 6 monitoring sections (SI-S6) along Beijiang River, the

bottom mud monitoring items basically meet the "soil environment quality standard".

The potential ecological hazard index evaluation method set by the Sweden scientist Hakanson

offers a standard for evaluating the potential risk of the sediment to the ecological system. The

potential ecological risk index is the sum of the potential ecological risk coefficients of the heavy

metals in the sediment. The calculating method is:

RI= LE, (J0-1); E, =T, i C, (10-2); C,= Cmi/ Cr, (10-3)

In the formula: RI is the potential ecological risk index, Ei is potential ecological risk index of the

heavy metal element of i, Ti is the toxicity response coefficient of heavy metal of i, Ci is the

geochemistry abundance ratio of heavy metal of i, Cmi is the content of the element of I in the

sediment, and Cri is the reference value used in calculation.

Take the highest geochemistry background value in the world before industrialization (see Table

4-4-1--4) as the reference value used in calculation and take the recommendation value (see

Table 4-4-15-3+ determined by Hakanson based on the element toxicity test and element

geochemistry abundance ratio as toxicity response coefficient. The ecological risk index may

indicate the potential impact of the heavy metal in the sediment, and Table 4-4-25-34 shows the

division standard of the ecological risk degrees of different index values.

Hakanson method is adopted in calculating the ecological risks of different sections. See Table

4-4-3-533.

The results show that all the ecological risk indexes of the bottom mud samples are less than 150,

82


indicating that the wastes of this project have little impact on the ecological system. Therefore, the

sediment can be used as general construction material or be used to refill the groin field.

4.4.2534 Analysis of Impact of Waste Dump (Disposal Area)

Chapter 2, Project Overview, clearly indicates the locations of the waste dumps, the amount of

waste, land type, land size, the water quality requirement of the area and the target of

environmental protection, etc. The known waste dumps are mainly located at the sandbank and

Groin field at the two banks of the river, and the sensitive environmental protection targets include

Wushi Power and Water Plant, (downriver 500m) , Qixinggang Water plant( (downriver 300m)

and several agricultural irrigating stations.

Among the construction sections, there are 12 work areas locate in the water source protection

area, including Lunzhou-Qingxinggang in Section ED, where dumping of wastes violiates the

ordinance of environmental protection on the water source protection.

According to the characteristics of the composition of the bottom sediments of Beijiang Middle

Reach (coarse sand and gravel and sands) as well as the above evaluation on ecological risks of

the bottom mud, the wastes have certain impact on the ecology, but the risk is slight. But in view

of protection of the water source protection area, it is recommended that the dredging waste of the

Lunzhou-Qingyuan Bridge river section shall not be disposed of in the filed or sandbank near

Ggroins, but at the low-lying land about 500m far from the bank (because the land protection area

83


of the water source protection area is within 500m), Therefore, it is recommended that the dredged

waste(sand mainly) can be -r4d as general construction material ul-'i be used in the revetment or

refilling the groin field in the upper reach which does not belong to the water source protection

area directly

4.5& Analyses of Impacts on Air

Dust emission in the construction process is the main factor of this project influencing the

environment air; the representative pollution index is gross suspending granule. Because the

construction period is long, and the construction of the main projects are in low water period, and

also because of the dry air and high wind speed in the autumn and winter of the year, dust

emission in the construction process can produce certain impact on the air.

On the basis of analogical investigation analysis, this report will give a comprehensive

consideration to the characteristic of pollution source intensity in the project construction process

and the pollution weather characteristic in the project area, and utilizes the methods of model

forecast and analogical analysis to forecast the impact of dust emission in the construction and

transportation process on the air of nearby objects.

4.5.1- The analyses of source intensity of dust emission

For waterway rectification project, the rectification measures usually include damming, dredging,

blasting of rock outcrops and so on, aiming to widen and enlarge the size of waterway, and keep

the stability the waterway, so as to realize the adjustment of flow velocity, the lowering of

admission value of shipping, the improvement of flow condition, and the expedite waterway.

The air pollution source of this project is mainly from dust in the process of mechanical digging,

filling, loading and unloading, mixing, and transportation during the construction, and from dust

emission in the process of transportation. The comparative research results of dust emission in the

process of project construction are shown in Table 45-1 -. According to table 4-5-1-, the

uppermost sources of dust emission in this project are the running of trucks on the temporary road

and wind striking in the construction scene.Table4l--1 The comparative research results of dust emission in the process of project construction

4.5.2- :.' Transportation Line, Operation Sites, Material Fields

According to the explanation in Chapter2, it is known that the traffic along the Northern River israther convenient. On the east bank the main road is Yin-Ying (Qingyuan-Yingde) Road (namedS203), and every village or town has suburban road leading to the docks on the both banks of theriver. 65% of the suburban roads are paved with concrete and others are paved with sandstone, soit is sure that the traffic can meet the demand of field construction and it is not necessary toconstruct extra traffic ways and temporary docks or widen any road for the project. The trafficprogramming during the project is shown in figure 2-2 and 2-3.

The docks on both banks are enough. The materials needed during the project can be conveyed bytruck to the nearest dock and then shipped to the construction field, thus much land will not beneeded temporarily. Task-Group has testified through investigation that the docks needed by theproject would include Chetouzhou dock, Baitu dock, Wushi dock, Kengkouzui dock, dock nearJiangkou town, dock near zhouxin town and so on. These docks will be used for transmittedconstruction materials, mainly stone, and sandstone secondly. The above-mentioned docks areshowed in figure2-2 and 2-3.

Local supply of construction materials: Construction materials needed by the project, like largescale concrete, stone and sand, should be purchased in the nearest market as a rule, and the sourcesof the materials are Shaoguan city, Yingde city and Qingyuan city, no more than 5-l5Km farfrom the construction fields. According to the consultation and investigation to local environmentdepartment, country-land department and constructors of sea-route bureau, all the stones neededfor this project are from local stone mines, belonging to local town or village (including GantangTown and Chishui Town of Shaoguan city, Baishiyao village and Guanyinyan village of Yingdecity, Yuantan town of Qingyuan city), and run by private institute legally. There are no villagesnear the mines. The locations of the stone mines, for the project, are shown in and table2-3 in detail. Due to the reason that we only need a small quantity of sand for the project (about2660 cube meters), the sand can be purchased from the local legal provider along the bank of theriver.

4.5.3- The analysis of the impact of dust emission

According to comparative research, TSP concentration increment values in the air produced bydust emission in the process of construction, and transportation on the condition of average windspeed are obtained in table 4-5-2Table 4 Daily average of TSP concentration increment values (mg/m3) ( Average wind speed)

According to the data about environmentstatus, the daily average TSP concentrations in Shaoguan,Qujiang, Yingde, and Qingyuan are respectively 0.14, 0.12, 0.20, and 0.14mg/mi3

According to the above comparative forecast results, without taking dustproof measures, after

85


superposing present concentrations, the following conditions are obtained:1) On dike construction site, TSP concentration reaches the evaluation standard outside 30m onleeward condition, and outside 20m on side wind condition;2) On both sides of the transportation road, TSP concentration reaches the evaluation standardoutside 70m on leeward condition, and outside 50m on side wind condition;3) Outside the piling site, TSP concentration reaches the evaluation standard outside 20m onleeward condition, and outside 1Om on side wind condition.Because the above-mentioned construction sites of this project are set within the dike, and use theexisting legal material sites, roads, and docks, this project will not make new sensitive areas. TSPconcentrations in the sensitive areas near the existing material sites, roads, and docks used in theconstruction of this project will increase, but the affected scopes are limited in the areas near thesite. After taking suitable dustproof measures, TSP concentration increment can be controlled to acertain degree. So the impact of the construction of this project on the TSP of surrounding areas isslight.

4.5.4.7.-.7 The analysis of the impact of dust emission on the residential areas

According to the above comparative forecast results, on both sides of the transportation road, TSPconcentration reaches the evaluation standard outside 70m on leeward condition, and outside 50mon side wind condition. The investigation of the sensitive areas along the transporting routeshowes that Chetou Village, Baitu Town, Wushi, Kengkouzui, Zhouxin Town, and Jiangkou Townare all within 50 meters from the road, so the TSP produced on the transporting road will impactthe residents in these villages and towns. As a result, some measures should be taken to reduce theinfluence of TSP.

4.6- The analysis of the noise produced by the project

4.6.1- Noise source intensity and noise forecast

The mechanical equipments used in the construction of waterway rectification project: dredger,bulldozer, concrete agitator, gross motorboat, tugboat, concrete pump, etc. The forecast results ofnoise produced by all kinds of mechanical equipments in different distances in the constructionperiod are shown in table 4-6-1Table4 6 -1 The forecast results of noise produced by all kinds of mechanical equipments indifferent distances IdB (A)l

4.6.2-. Objects that may be impacted by transportation noise

The construction of the project is executed mainly on the water, and belongs to the movingconstruction along the river. Stone, sand, and other building materials are transferred at theexisting transportation docks along the river, and piled at the temporary construction sites. Themain objects influenced by the construction of the project are residential areas and sensitive areasnear the transportation routes and the piling sites, and there are no residential areas and schoolswithin the scope of estimation. According to the reconnaissance on the construction route, themain roads on the east bank of Beijiang River are Yinying Road (Qingyuan-Yingde)(S203) andthe simple transportation route leading to the operation docks on both banks of Beijiang River.The residential areas (the distance is about 50m with road) involved by the project are: ChetouVillage, Baitu Town, Wushi, Kengkouzui, Zhouxin Town, and Jiangkou Town. The positions ofthe above residential areas are shown in Fig. 2-3. According to the reconnaissance on theconstruction route, there are no residential areas near the above docks.

4.6.3- Analysis of noise caused by operation boats

According to the waterway map, the central line of Beijiang River waterway is 100-200m fromthe both sides in general, and the distances reach 500m in some river stretches. So the constructionon waterway surface has little impact on the sensitive areas along both sides; while stonetransportation trucks have certain impact on the sensitive areas along both sides.As illustrated in the supervision studies performed by our institute on EIA of Chencun WaterChannel of Guangdong (2000), the noise level of a horn at 200 meters away from the operationboats is about 75-85dB, and will have a transitory impact on resident along the bank, so the shipsof the project are forbidden to horn according to relevant regulation. While the sound level of adiesel engine at 200 meters away from the sailing vessel is about 50-6OdB.The noise standardalong the waterway banks basically reaches the class 4 of Regional Environmental Noise Standardof the City, so the impact of the shipping noise on the residential and business area is quite slight.

4.6.4- Analysis of noise caused by transportation

According to the forecasting result, the transportation noise along the transporting road cannotreach the class 4 of Regional Environmental Noise Standard of the City until 50 meters away. Sothe resident within 20 meters far from the road will be impacted by the noise. These impactedvillages include Chetou Village, Baitu Town, Wushi, Kengkouzui, Zhouxin Town, and JiangkouTown. Therefore, measures must be taken to reduce the noise pollution and the intensity of thetransportation noise.

4.7-The analysis of the impact on the safety of ships and roads

during the construction period

According to the analysis of the construction period of the project, because of the small amount ofgeneral construction quantity, long construction route, dispersed construction sites, 4-yearconstruction period, the broad Beijiang River waterway, wide sand beach, and good constructioncondition within the dike, the normal transportation of ships in the whole construction period isseldom influenced.According to the actual observation on the gathering site of the existing construction dredgers on

87


the surface of the river, the numbers of ships and the construction proiect in different construction

sites have only a slight impact on the normal operation of the waterway,So the scientific management in the construction period, the reasonable arrangement of theconstruction procedure, the optimization of the construction intensity, the overall consideration of

the construction plan in the construction site and the transportation of the existing waterway will

make the construction of the whole project more favorable to the safe transportation of the

waterway.

During the constuction period, trucks and other construction vehicles will congest roads that areused for material transportation. According the engineering feasibility report. the main

construction material needed is stone, and it will not cost much work in transportation.

Furthermore. the traffic on this route is comparatively not so busy in existence. During the

construction period, trucks and other construction vehicles will not congest roads that are used for

material transportation. Even though the traffic lam will occasionally occur. it will be solved and

the normal transportation will be maintained under the regulation of the local transportation

management staff. Anyway. in order to assure the normal and good traffic condition. truck driversshould be well informed on traffic safety, appropriate signs should be displayed on the roads. andstaff if necessarv should keep traffic order.

4.8-The analysis of the impact of the project on drainage facility

The economy of the towns and villages along the middle stream of Beijiang River is notdeveloped, and Beijiang River is the main source of industrial, agricultural, and living water in

towns and cities. The distribution and explanation of water supply facilities affected by this

project are shown in Fig2-2a, b. Most of these water supply facilities belong to the

multi-functional medium-size or small-size intake facilities built in 1960-1970, and some of them

have been stopped from using. They are mainly used for farmland irrigation and drainage, thewater use in fishpond, water use in enterprises, etc. These water supply and drainage facilities are

mainly designed and built according to the past hydrological condition. Water intake is

underground self-irrigation pumping, and is usually designed on the hydrological condition of the

furthest low water. There are no drainage gates or large urban drainage system on any of therectification river sections. So, according to the analysis on the feasibility report of the project, therectification project of waterway will result in the temporary or permanent changes of partial

hydrological elements in the process of the construction and after the construction. The changescope is slight, so the impact on the water supply and drainage projects on both banks is also

slight.

4.9- The analysis of Conservation of Water and Soil

This Chapter is based on the plan of conversation of waler and soil of Beijiang Middle Reach

(Shaoguan--Qingyuan) Channel Improvement Works submitted by Guangdong Water

Conservation and Water Electricity Academy.

The purpose of the channel rectification works is to improve the channel depth and navigation

conditions in low flow period.

During the period of construction, the water level is low and the improvement buildings are low.And only when the water level is equal to the dam, the water flow will be restrained from

enhancing the ability of moving the riverbed sediments, making the river meet the designed

88


channel depth. The scope of the water improvement works is very small, and it will not impact the

two banks of the river or cause the problem of soil erosion. The cutting works are mainly

implemented in dry season, and the improvement line will be long, with excavated volume of

about 250,000m 3. During the process of construction, some loose excavated soilwill cause soilerosion in rain scouring. Calculate as per accumulating slope soil erosion modulus of 12,800t /

km2 with soil erosion period of two years, the volume of soil erosion of such works will be 3200t,so the excavation works will be the key point for prevention of soil erosion in this project. The

bank protection engineering earthworks volume will be 28,800m3 .In the flood period, all the buildings will be deep in the water. With increase ofwater level, the

water depth of the top of the buildings will increase, which will lose the function of improving the

water level and will not constitute threat to the river banks. In the flood period, the main factors

endangering the banks and the embankments are big runoff, high flow velocity, turbulence caused

by hard rocks at high water level, waves caused by wind and by boats. According to the feasibility

study of the engineering, the current embankments are all built by the water Conservation

departments, with flood control altitude, embankment deployment, structure, flood control and

flood draining capacities unable to meet the flood control standard, and the influence of soil

erosion is slight. So in this rectification work, treatments will be done to the bottom of the

improving buildings, and to the length and width of bottom or partial quays, while no measures

will be taken for the banks and the embankments.In general, the possibility of soil erosion of this work is slight. The soil erosion mainly appears in

the cutting excavation process, but this process will last only for a short time. The interim

measures of conversation of water and soil and reinforced non-engineering measures may be taken

to enhance construction management so as to further control the soil erosion.

4.10 Analysis of Influence on Cultural Relics

According to the preliminary survey on the cultural relics within the scope of the BeUiiang Middle

Reach construction section. bank revetment and the material excavation ground. there are

important ancient relics that should be excavated at the construction area of the waterway

rectification project. So the project construction will have no direct influence on such cultural relic.(for details. read the special report on cultural relics !

4.11 Analysis of Influence of Risks and Accidents on Freight

4.11.1 Analysis of Freight Situation and Estimation

(1)Situation

According to the statistics of freight flow situation. the goods under freight downward on Beiiiang

River mainly include coal. metals. minerals, cement. wood and other daily articles (including

grain. fertilizer, agricultural byproducts, industrial consumer goods etc). In 2000 the freight

volume was 1.7905 million tons: the goods under freight upward to Beiiiang River mainly include

petroleum. fertilizer. pesticide. machinery, electrical appliances, light industrial products and

medicines, and in 2000 the freight volume was 1.4495 million tons. From the foregoing chapters.

it is obvious that the water freight volume declined during 1999-2001.

(2MEstimation

According to the relevant data of the national economy development along the line, the water

89


freight goods at the Beiiiang River system will still be the minerals, building materials and coal.

As the highways between the regions. especially the Shaoguan-Yingde-Oingvuan-Guangzhou

high-grade highway. are more and more developed, most of the pesticide. fertilizer and chemicals

and medicines will be transported through highway. so the proportion of water freight volume will

be reduced,

4.11.2 Survey of Frequencv of Accidents

According to the interviews among the departments of environment protection. water freight.

agLriculture. fishing and communications in Qingyuan. Yingde and Shaoguan. for the last 15 years

since middle 1980s. no water transportation accident on the Beijiang river channel has been

recorded. It is obvious that the water transportation accident rate is low. This may be attributed to

low traffic volume. small ships's density, good river navigation conditions. and small ship tonnage

that is easy to operate.

4.11.3 Analysis of Influence of Transportation Accident on Environment

According to the above survey. the main goods under freight on Beijinag River are non-dangerous

goods of building materials (cement, sands. coarse sand and gravel), minerals. coai. grains and

woods. and the dangerous goods of pesticide, fertilizer and chemicals account for only a small

percentage (occupying 0.01-2.78% of the annual total freight volume), As the possibility of

transportation accident is very low on Beiiang. the influence of transportation accident on the

environment is little.

5. Cumulative and Indirect-induced Environmental Effects

Assessment

It is the World Bank's requirements for borrowers to conduct Cumulative Environmental

Effects Assessment (CEEA), in order to assess the impacts resultine, from a series of similar

proiects (existing, proposed or planned) within a defined environmental system and having a

similar scope of impacts, and to conduct Induced or Indirect Environmental Effects Assessment

(IEEA). in order to assess the impacts resultine from induced or indirect proiects that will proceed

oniv if the proposed proiect proceeds on a defined environmental system.

It was discussed and reached an agreement between the World Bank Working Group and

Environment Consultation Team for the proiect during the 3rd discussion, March 2003. Shaoguan.

Guangdong. China. that The CEEA and the IEEA should forn a separate chapter of the

Environmental Impact Assessment report. This chapter S includes two parts: CEEA and IEEA.

5.1 Cumulative Environmental Effects Assessment (CEEA)

5.1.1 The Rationale

In line with the requirements by the World Bank, a combination of series of similar proiects

will collectively alter the environmental balance of a receivine system, and may result in net

long-term degradation of a system or region. The World Bank lists, therefore, four "tests" that can

be applied to a proiect to determine the need to conduct a CEEA, e.g., Test 1: a series of similar

sub-components of the proposed proiects that will impact a common receivine svstem: Test 2:

existing and future projects withi the critical aspect of similaritv of the proposed project within one

receivill,n envirolinment systeml: Test 3: the natiure of the proiect not the responisible party or project

proponient: and Test 4: all project componients vill create siiijlar impacts during both construction

and operationi phases to a comimlon receiviin systemil.

The North River (Shaoeuan-Qineyuan Section) waterwva) regulation sub-component is alontg

the North River, Shaoguan to Oingyuan section. Along the waterway section, three dams have

been constructed and formed reservoirs, which have the potentials to greatly improve the

navigation condition of the North River waterway (Shaoguan-OingYuan). The proposed project

aims to take the advantages of improved navigation conditions in the three reservoirs formed by

the existing dams in order to further improve the whole North River waterway

(Shaoguan-Oingyuan).

5.1.2 Relative Proiects and Their Cumulative Environment Effects

91


Along the North River Shaoguan to Oingyuan section, existing three dams, three shiplocks,

and relative three reservoirs formed by the dams, and the sub-components of the proposed

waterway regulation proiect laying out alonre the three sub-sections along the North River

Shaorzuan to Oinzyuan section. may cumulatively impact the North River environment, mainly

focusing on aquatic ecosystem, aguatic living resources, and water quality, especially drinking

water quality. While the cumulative impacts of the existing projects and proposed proiect on the

terrestrial environment system may restrictedly limited or negligible from the professional

judgments based on the experiments learnt from the previous projects in the similar environment

systems in Guanedong province and other regions in China.

5.1.3 Cumulative Environment Effects Assessment

Cumulative Environment Effects Assessment for the proposed North River

(Shaoguan-Qingyuan) wvaterway regulation and the relative existing projects along the North

River Shaoguan to Qinegvuan section is summarized in Table 5-la and Table 5-lb for the

5.2.1.2 Social-Economic Development Master Plan in the Watershed(1) Qingyuan Citya) Urban Area Development Master Plan

According to the general city plan of Qingyuan, the Qingyuan city development aim is

positioned as: portal at the back of Pearl River Delta, a political, economic and cultural center,

combination of industry, trade and tourism, with focus on light industry processing, a modern

garden riverside city with good ecological environment.b) River Banks Development Master Plan Within the City

According to the planning, the areas of the two banks of Beijiang River are planned to be

scenery regions with emphasis on tourism and entertainrment. The area between Jinbi Garden and

Lunzhou Island, southern bank, is planned to be riverside green land. The Feilaixia Scenic Spot is

evaluated as a scenic spot of national grade. Along the river, the main scenic spots on the south

bank include: viaduct, violet bamboos, Zhongtan, Xitanyinyue, Yuzhouchangwan etc. On the

north bank are Baihmiao Folk Culture Village, Jushixuanteng, Feilai Temple, Qiandaogufeng,

Baihuatan, and Xiajiangbeilin etc.

(2) Yingde Citya) Urban Area Development Master Plan

According to the general city plan of Yingde, the Yingde city development aims at: a political,

cultural and communication center, a composite city with focus on building materials and

processing industry, tourism, and sports undertaking.b) Two Banks Plan of Beijiang River Within the City

According to the planning, the areas along the two banks of Beijiang are planned as: dividing

the beach lines into natural beach line landscape and building beach line landscape. The former

focuses on the natural landscape of water body, grass, flowers, and trees as background, and the

latter on the buildings of different styles as the setoff. The two landscape lines form a water area

beach line landscape zone. In addition, the riverside Scenic Spots also include the Guanyinyan, 20

96


km from the city proper.

Waterway tourism: based on the plan, Wangpu-Yingcheng-Qingyuan Feilaixia waterway

tourist route will be developed, along with the mountains at both sides of Beijiang, Baojingong

Scenic Spot, Guanyingyan and Feilaixia scenic spot.(3) Shaoguan Citya) Urban Area Development Master Plan

According to the general city plan, during the "Tenth Five-Year Plan" period, the economic

development in Shaoguan is focused on heavy industry, especially the non-ferrous metallurgy and

steel industry, integrated with advantages of different industries. The focus of industry will be at

tourist zone and catering production, with construction industry as the means, the agriculture as

the basis and the transportation industry and post and telecommunication industry as the links.b) Two Banks Plan of Beijiang River Within the City

According to the planning, the areas of the two banks of Beijiang are planned as the

following: with landscape as the link, creating three series of landscapes of mountain, water, and

city, making the mountains, waters, and the city mingled with each other, and creating the feature

of "Landscape City". Along the banks of Beijing River, there are Beijiang Island Riverside Trade

Town, Mengzhouba Water Amusement Center, etc.

5.2.2 Main Economic Activities Relative to the Proposed Project

The freights on Beijiang River mainly include coal, cement, mineral building materials and

other goods. So it is obvious that with the improvement of the navigation in the North river,

economic activities in the upper reaching areas will enjoy certain growth, such as the building

material industry, agriculture, forestry, fishing, mining, tourism and other industries.

5.2.2.1 Coal Freight Increase but the Coal Output in the Watershed Decrease

The coal is the traditional freight goods on Beijiang River, mainly from Shanxi and Hunan

Provinces in the central and northern China. In 2000, the coal freight volume through Beijiang

was about I million tons. While the coal freights through the North River in 2005, 2010, and 2020

are estimated 1.3 million tons, 1.57 million tons, and 1.96 million tons, respectively. According to

the regulation on the management of mineral resources set by Guangdong provincial government

and the local governments by the North River, most of the private coalmines had been closed or

will be closed, and the vegetation will be planted on the mining sites. Consequently, the ecological

environment in the upper areas will be recovered and improve greatly. The coal output in the

northern area of Guangdong will decline dramatically. It can be concluded that the coal fright

through the North River will have positive indirect effects. on the North River watershed.

5.2.2.2 Cement Production

The cement is the traditional freight goods on Beijiang River; mainly from Qujiang and

Yingde. Guangdong province has given its emphasis of cement production to the above two cities.

97

Environmental Impact Assessnientfor Northz-River(Sltaoguan-Qingyuan) Waterway Regulation Project

The river navigation is one of the economical and reasonable transportation way for cement. In

2000 the cement freight volume through Beijiang was 0.4355 million tons, and after Beijiang

rectification, the cement freights through the North River in 2005, 2010, 2020 are estimated 1.18

million tons, 1.62 million tons and 2.94 million tons, respectively. Obviously, induced expands of

the cement plants along the North River will increase the impacts on the local environments.

5.2.2.3 A Limited Increase of Mineral Building Material Freight

At present, the mineral building materials (sands and coarse sand and gravel) are mainly

excavated at the river channel of Beijiang River Middle Reach, mainly exported by shipping. In

2000, the freight volume throughi the North River (Shaoguan-Qingyuan) was 0.413 million tons.

Thanks to the strict control on the sands excavation volume on Beijiang Middle Reach by the local

water conservancy department, the mineral building materials exported from Beijing River in

2005, 2010, 2020 are estimated 0.45 million tons, and effort wvill be taken to control it under this

level. It can be concluded, therefore, that the Limited Increase of Mineral Building Material

Freight will have only negligible impacts on the regional environments.

5.2.2.4 Other Goods Shipping through tthe North River

Other goods shipping through the north river include agricultural and forestry byproducts,

electronic processing, light industry and medical products, and chemical materials. The Northern

area is the forestry production base of Guangdong Province, where the forestry byproducts and the

ecological environments are well protected and exploited under the strict regulations for natural

resource reservation. According to statistics, the forestry byproducts freight volumes in 2005,

2010 and 2020 are estimated 28 thousand tons, 33 thousand tons and 60 thousand tons,

respectively.

5.2.3 Overall Indirect Effects of the Social-Economic Development in theRegion

5.2.3.1 Favorable Influence to the Regional Environments

From the above descriptions and analysis about the

of situation and general city plan It is obvious that concerning the economic development

situation along the two-bank area of Beijiang River, the river channel freight scale is rather small.

freight volume in Shaoguan accounts for 3% of the total social freight volume, and Qingyuan and

Yingde account for about 20-24.6% (including the statistics data of the freight volume of the

branches). The planning and construction along the line are mainly on the tourism landscape

ievelopment and river channel freight. The waterway rectification and the.bank protection work

will deepen the river channel and reduce the soil erosion of the two banks and deposit of mud and

sands, thus to reduce boats jamming to a certain extent to save the cost of goods transportation and

:o be favorable to the tourist development and shipping along the line, especially in Qingyuan and

98

Yingde.

5.2.3.2 Adverse Influence to the Retional Environments

The adverse influences of the proiect on the social economy mainly appear during the

construction period. See other chapters on environmental influences.

5.2.4 Cumulative Impacts in Operation Phrase

5.2.4.1 The Demand of the Proiect

From a viewvpoint of the social-economic development, the demands for the proiect are as the

following:

1) The North River Middle Reach run through the northern mountainous area of

Guanedone Province, where the natural conditions set very strict limitation to the highway system

development. North River waterway regulation aimed by the proposed project to improve the

navigation for shippine transportation in the North River Shaoeuan-Oingyuan section has certain

preparative advantage, and therefore wvill provide a convenient transportation way to the regional

social-economic development.

2) Different industry sectors developed alone the North River middle section supply a lot

of materials that need to be transported outside. In this region, the shipping transportation in the

North River Shaoguan-Qingyuan is one of the main transportation ways added to land

transportation. The shipping transportation capacity in the North River Shaoguan-Qingyuan

section resulting from the strict waterway conditions has frequently caused ship iamminc in the

past. Ship iamming happened most freguently in the Oingyuan section, which causes a great threat

to the water quality of the drinking water source protection zone. The proposed proiect will help

the sustainable development of Oingyuan and other areas in the North River basin.

3) Tourist resources are rich along the North River Shaoguan-Oingyuan section. The

improvement of the waterway will benefit to the tourism industry development in the North River

Basin.

5.2.4.2 l'ossible Effects of the Economic Activities Relative to the project

Previouls analysis shows that the improvement of the shipping condition after the proposed

proiect will drive the development of relevant industry sectors. The industrial development in the

region will inevitably bring influences on ecological environment in the North River basin. The

previous analvsis also indicates that the influence of the industrial development in the region to

the environment is small.

5.2.4.3 Mitigatory Measures for the Cumulative Effects1) Prosperity of shipping transportation will lead to the increase of ships. and in turn, more

ships will discharge more contaminants to the North River if the ship wastes are not controlledeffectively. The effective administration is necessary for the increasing ships, and for thewastewater caused by the ships shall be treated by the wastewater collection and treatment

99

Environmental Impact Assessment for Nortil-River(Slzaoguan-Qingvuan) Waterway Regulation Project

facilities set up at the main wharfs. The wastewater treated shall not be discharged until it canmeet the standard. The wastes of the ships shall be sent to the wharf for collection before beingtransferred to the municipal garbage disposal plant, and shall not be discharged withoutpermission.

2) The development of minine industry and building materials is closely connected to thelocal natural resources. If such resources are not under comprehensive development, scientificmanaZement and orderly utility. it will cause waste and will accelerate exhaustion of the resources.So in the process of exploiting such resources, reasonable plan and site selection shall beconducted carefully to avoid environmental problems.

3) The possible environmental problems from development of the local agriculture include:the farmland utility is reinforced while the land maintenance is neglected, and increased use ofchemical fertilizer and pesticide will lead to new pollution. Unreasonable plantation of thefarmland resources will cause new soil erosion. In view of these new environment problems, it isnecessary to make overall plans and take all factors into consideration for comprehensive planningand scientific administration to solve the old and new problems with new agricultural technology.such as development of "high-tech farming with high yields and high returns" and solid ecologicalagriculture, conducting prevention against plant diseases and insect pests, and adopting effectiveand low-toxicity pesticide to minimize the influences of agriculture on environment.

5.2.5 Existing Manaaement Framework and Programs for the North River

Environment protection, irrigation, navigation and other relative departments to the

management of the North River along Beijiang, each has its own responsibility and has developed

management programs for the North River.

6.Mitigation measures, Suggestion and Budget for Project

6.1 Mitigation Measures and Suggestion on Water quality

During the dredging construction period, the following mitigation measures should be taken to

protect the water environment.

( I ) The environmental protection matter in surrounding water area should be fully

emphasized during the dredging construction period. The dredging construction within the water

protection area in Qingyuan should not be operated without permission of locad EPB. Extensive

sections of exposed river bank in various construction areas will be protected from erosion by use

of geotextiles to protect the water from pollution; and he task of water quality monitoring should

be well enforced in the stage of construction.

(2) Employing advanced construction equipments according whith the nation

relevant technique request, optimizing construction techniques During construction in

river sections between Qingyuan Feilaixia gorge and Qingyuan Beijiang Bridge and between

Yingde Baishiyao and Daluodu, owning to the sand deposit property of riverbed, hydraulic

dredging equipments with low pollution (such as Suction dredger)should be employed to reduce

mud leakage and re-suspension during dredging.

(3) The contractors should consult with and get authorization from the project

office before starting the work. arranging the number, location and dredging schedule of

watercrafts to reduce the stirring strength and influence extent of the dredging area and its bottom

deposit, especially to reduce the dredging strength towards river sections between Lunzhou IQ

Qixinggang and the downstream reach of Wushi power plant. When dredging along the wate

intake zone of water supply, the construction must notify water plant carefully monitor water

quality , and temporarily cut water supply when necessary. Because the period of highest

demands on potable water usually in daytimes, construction should be operated at night, to

avoid affecting water supply as far as possible.

(4) When constructioning watercrafts have site-fixed operation, are at anchor in the water

area, ship anchoring and or are having construction encamping, the construction watercrafts

should select rational environmental protection measures based on the condition of the

construction sites property, so as to avoid accidents of water area pollution by ship contaminants.

Among them, the oil-containing sewage generated by construction ships watercrafRs must be

collected and processed uniformly by oil-water separator, and then discharged when reaching the

disposal standard. The sewage generated by the work staff at the construction watercrafts should

be reduced to the lowest degree. And the disposal of trash from the construction crafts should

strictly abide by the Disposal Standardfor Watercrafis Poll.

101


6.2 Mitigation Measures and Suggestion in Dredging Sediments

Disposal

In the process of removing of dredging sediments, the following measures should be taken:

(WLAccording to the of riverbed deposit in Beijiang, the contents of

organic material and heavy metal in dredging sediments are little, so the harm to environment

caused by them is negligible Considering the water source protection area in Qingyuan, however,

it is suggested that the dredging sediments should not be placed in areas between groins. But in

low-lying areas 500 meters from the river shore (the land protection range of water source

protection area), and that protection measure should be taken to preserve water and soil. Therefore,

according to the newly Possibility report of Beiiiang. the dredging sediments (mainly containLsand

and scree)_all will be used in the revetment or the refilling of areas between groins for the

Pwjecj. The deposition in these areas will further enhance the river regulation created by the spurs

and the channel dredging.

(2-) When digged silt and earth stone pile are temporarily placed on riverside, the

locations should be selected based on the standard that they are not easy to be eroded, such as

low-lying beach, and the simple cofferdam and barrel-drain should be built beforehand to

prevent direct influx into river and small quantity of slop of the sediments.

(i-) To guarantee construction security during dumpage of dredging sediments and

rational operation of periphery river-route and other water area functional sections, the obvious

signs should be set outside the dumpage sites, to facilitate construction ships enter and practise

dumpage task, and avoid unnecessary pollution accidents. Meanwhile it should be performed with

permission of administration department.

(4-) The dredging crafts must strictly follow the proposed channel alignment and dispos

of dredged sediments the sediments in the dumpage sites. It is forbidden to discharge the

sediment beyond the appointed dumpage sites. According to the experience of dumpage practice,

it is important to follow the above rule in order to reduce the impact on the water environment

around the dumpage sites to the minimum degree. Some personnel can be arranged to supervise

the dumpage actions if necessary.

(6) No leakage is allowed when the dredging crafts transport the sediments to the dumpage

sites. At the same time, the construction group should have close contact with the local weather

report department, so that precautions can be taken in advance in case of bad weather. For

example, they can stop dredging or dumpage when the know it is going to rain.

(7) It is necessary to have a good performance at the sediments monitoring during

construction.

6.3 Mitigation Measures and Suggestion on Air Environment

In order to protect the air environment in the residential area along the transportation route,

102


the following mitigation measures should be taken during the construction period.

( I ) The dropped trash in construction docks should be cleared regularly, supplemented

with necessary measure of spreading water to repress dust, no less than two or three times each

day, to keep ground without flying dust. To spray water on roads within 50m near Chetou Village.

Baitu Town. Wushi, Kengkouzui. Zhouxin Town. and Jiangkou Town.

(2) When vehicle carrying earth stone pile, sand gravel stuff, cement and other building

materials enters the site, it is necessary to cover stuff that generates dust easily with cloth, limit

velocity of passing vehicles, decrease falling gap of loaded materials, and avoid leakage caused by

gale weather or road wallow.

(3) According to the local dominating wind orientation and distribution of sensitive points

in surrounding environment, piling field and concrete mixing field should be reasonably arranged

during construction. such as 200 m or more away from and. if possible. lee-side of the residential

areas. Meanwhile the stuff of easily flying dust should be piled in warehouse and covered with

cloth.

(4) The construction management department should pay attention to weather forecast in

construction area, and do well in the flying dust prevention works. Measures of spreading water,

covering and suppressing stuff in the bad weather conditions of great wind and dryness should be

taken.

(5) Construction sections should cooperate with local environment protection inspection

staff, to strengthen inspection to key district, such as near Chetou Village. Baitu Town. Wushi.

Kengkouzui. Zhouxin Town. and Jiangkou Town. and survey the TSP concentration in atmosphere

circumstance so as to supply data for effective control of TSP pollution.

(6) It is necessary to carry out air monitoring during construction.

6.4 Mitigation Measures and Suggestion on Construction Noise

( I ) To reasonably arrange the operation time (construction will be forbided in nighttnme)

of docks and schedule of ship construction and strengthen supervision and management of

construction docks and transport routes. to avoid impact on sensitive points in surrounding

circumstance.

(2) To select with priority the construction equipments according with the nation relevant

technique request and low noiseand concentrate on the regular maintenance and repair of

construction equipments for keeping their good running status.

(3 ) To regulate and administer uniformly the construction vehicles and control the vehicle

flow density. To effectively decrease the times of horning when entering the leave fields and

installs noise suppressor of vehicles for effectively reducing impact of traffic noise on

surrounding circumstance.

(4) To carry out noise monitoringgduring construction.

103


6.5 Mitigation Measures and Suggestion on Land Ecological

Environment

The prefered order of mitigation measure to reduce the ecological impact is: avoidance,

reduction, restoration or rebuilding, and compensation. In the factual implementation, the

reconnaissance and selection of guarrv is based on the synthesized considerations of location

factors, including repair engineering section, demand capacity, transport condition, stone stuff and

reserve. Therefore, the emphasis of mitigation measure is reduction of ecological destroy, and to

restore the ecological system similar to or more eminent than the existing status after stone

mining.

( I ) To Reduce Ecological Influence via Optimizing Choice of Ouarry

Because the quarry is pre-selected basedon the engineering demand capacity, the reserve of

stone in every field is abundant. It is proposed to choose and mine the stuff fields with little

vegetation covering, small biological mass quantity, and bad ecological quality, under the

circumstance of good road and transport conditions, but retain the stuff fields with good natural

vegetation structure and eminent ecological quality.

(2) Compensation for Environmental Impact and Rebuilding of Ecological Circumstance

If some organic species and ecological circumstance are affected by the engineering, the

engineering group will compensate by the means of restoration of similar ecological

circumstance with same species. Because the organisms destroyed in the engineering are local

common species, the restoration of ecological circumstance can be fulfilled by means of planting

the local species. In deed, the newly constructed ecological system shouldn't be thoroughly the

same as the forner one; the restoration should be fulfilled based on the actual conditions and

optimizing combination choice of species.

(3) Take measures of soil and water conservation in quarry site. Use the earth bags to preventthe soil erosion during the construction. Accordinn to the local condition. bermude. Iawngrass.

and axonopus compressus can be planted on the riverbank and Quarry sites .

6.6 Mitigation Measures and Suggestion on Aquatic Organisms and

Fishery Resources

(I ) To dredge in separate section manner and decrease the dredging intensity so as to

benefit the adaptation and restoration of fishery resources and organisms.

(2) The construction time shouldn't conflict the reproducing and growth season of fish

resources that is usually from May to July for dominating fish species in Beijiang River.

(3 ) The construction units should consult fishery administration department, to guarantee

the least loss of fry. After construction, the construction units should pay some

economiccompensation to the administration department through negotiation, providing some

capital to buy fry and cooperating with fishery administration department in fry breeding to restore

104


fishery resources

6.7 Emergency measures of unexpected traffic accidents

It is suggested that the waterway management department should intensify the supervision to

the ships transporting toxic and harmful materials. The transportation of dangerous materials

should be registered to the public security departments of communication. Relevant managerial

staff and the employed should get on-the-job training, and those on duty must hold license so as to

prevent the accidents of leakage from happening. In case of leakage accident, such responsible

departments as the public security department, the environmental protection department and the

communication department must be informed in time, and the personnel, vehicles, facilities and

medicines should be well organized in the emergency treatment so as to control the influence area

of the accident to a minimum scale.

According to the above table. for river section A. comparing with Scheme 1. the constructionwork amount involved in Scheme 2 is smaller, mainly including dredging and the construction ofspurs and groynes. But. in Scheme 2. destructing and reconstruction of spurs and groynes and

117


blasting rock shoals will cost much more work force than that in Scheme 1. What's more.Scheme I is favorable to the environment since it doesn't involve the Blasting rock shoals.Therefore. Scheme I is recommended in view of its total work amount.As for river section B. the situation is similar with river section B. the construction work amountinvolved in Scheme 2 is smaller. mainly including dredging and the construction of spurs andgrovnes. But. in Scheme 2. destructing and reconstruction of spurs and groynes. dredging andblasting rock shoals will cost much more work force than that in Scheme 1. Furthermore.Scheme I is favorable to the environment since it doesn't involve the blasting rock shoals.Therefore. Scheme I is also recommended here.

7.2 Comparison of investment cost

Comparison of investment cost of two schemes is shown in Table 7-1-2.

Table 7-2-1 ComDarison of investment cost of two schemes

i=em Scheme I (R260m) Scheme lI(R260m) Difference (11- 1)

Estimation of

investment cost (1000 186895.30 246436.60 +59541.30

yuLan )It is obvious that the investment cost of scheme 11 (R 260m) is much higher than scheme I(R260m). and the higher cost is about 32%.

7.3 Comparative analysis of alternatives on Environment Impacts

The main types of regulation work of each alternative and its environment impacts are different:

( I ) Blasting rock shoals. which generates great noise and strong bow wave, will have some

impacts on surrouliding residents. buildings and aquatic organisms. especially the fish. These two

schemes have distinct amount of blasting rock shoals. and consequently its environmental

influence are different. In general, the larger amount of blasting rock shoals. the more serious

environmental intluence it will result in. Between the two schemes. the recommended scheme I

has not blasting rock shoals. so its impact on environment is much less than another one.

(2) Generally when the amount of dredging work increase, the duration of construction will

increase, and the cast unloading of dredging will also increase as well as the total amount of

suspending sediments in water body. That is to say. when the amount of dredging work grows, its

influence to ecological environment will increase accordingly. Comparing the two schemes. the

scheme 2 has the least underwater dredging (846456m 3): the scheme I (902176m3! has the bigger

environmental influence.

(3) The more engineering quantities involved in spur construction, the more impact it will have

on environment. Comparing the two schemes. the scheme I has the least engineering quantities

(962817 m3) of spur construction. and the scheme 2 (965654 m3! has the bigger environmental

influnce

(4) The engineering of spur removing is actually a behavior harmful to the ecologic environment

for aquatic life. Between two schemes. the recommended scheme I (3240m3 ) has less spur

removing than the other one (l8480m3 ). and its influence to ecological environment is also much

less than the other one.

118


7.4 Integrated assessment

(1) Two schemes also meet the grade V of standard of freshwater waterway construction.

(2) Two schemes are also good economic efficiency. and their internal earning rates are higher

than the standard-12% of social discount rate Two resist risk very well.(3) The construction work amount involved in Scheme 2 is smaller than that involved in Scheme 1.But. in Scheme 2. destructing and reconstruction of spurs and groynes, dredging and blasting rock

shoals will cost much more work force than that in Scheme 1. Furthermore. No involvement ofreef blasting in Scheme I favors the environment, and becomes another attraction of Scheme 1.Therefore. Scheme I is also recommended here.

(4) The earth and stone materials needed in the construction involved in Scheme I is less than thatin Scheme 2. and it means that Scheme I will have less impact on the environment. So Scheme Iis again preferred in view of its environmental impact.

(5) The forecasted investment of Scheme I is about 32% less than that of Scheme 2. So we choose

Scheme 1. in this way. a large amount of money will be saved from the construction.(6) Combining all above mentioned reasons. we recommend Scheme I in the Waterway

Upgrading Project of the Middle Stream of the Beiiiang River. The size of the upgraded waterwaywill be 1.3 meter deep. 40 meter wide and the curve radium will be 260 meter.

7.5Analysis of "Non-program" Alternative Project of Waterway

Uperading Engineering

According to the demand of local economic development, this evaluation suggests a project of

replacing land transport with aquatic transport that is the project of replacing constructing

highway with Beijiang waterwav rectification. It is analyzed with comparison as follows.

First after constructing highway, the freightage has incomparable advantage on time.

efficiency and immaterial benefit. and it will stimulate the economic development in mountain

area. However it has some limitation: ( I ) It cannot resolve the contradiction between shipping

transport and Darn construction: (2) It cannot guarantee the security of river bank: (3) It

cannot resolve the water pollution by ground watercraft in Qingyuan river section and ensure the

security of water qualitv in water source protection area (water plant): (4) As the North

Guangdong areas belong to mountain area. highway construction will produce much greater

environmental matters than waterway rectification engineering, such as ecological destruction.

vehicle gas pollution. highwav noise. and loss of water and soil: (5) To construct a 184km high

class highway. the total investment. including investment of environmental protection. is much

larger than this project: ( 6 ) In the case of highway transport. the accident and risk will increase.

even intimidating people's life.

According to the transportation data in this area in recent years.(eg. waterway transportation

volume increases by 10-30 percent annually in Shaoguan City while the land transportaiion

volume increases only bv 10-20 percent annually in Qingyuan City.) and the regional economic

development trend. the transportation volume in this area is expected to enjoy an obvious increase.

119


Without this proiect. the waterway transportation capability in the middle reach of the North River

cannot be improved, and the land transportation will face great pressure. The total investment in

the construction of highway. including investment of environmental protection. is much larger

than this proiect. and highway construction will also bring great damage to the ecological

environment due to the fact that this area is mainly composed of mountainous land. Furthermore.

the cost of highway transportation is much higher than that of the waterway transportation. The

details showed in Table 7-5-1.

By comparison mentioned above, the waterway rectification in the middle reach of Beijiang

River in a given period will be able to resolve these above-mentioned limitations unable to be

resolved by highway construction. Therefore, this evaluation draws a conclusion that this

waterway rectification project is more preponderant and feasible than highway construction.

8.1.3 Public Opinion

8.1.3.1 Public meeting and face to face interview

The public gave priority to the following:

Priority should be given to the protection of drinking water quality and tourism resource in the

project phase, particularly to Qixinggang water plant; andNavigation should be improved. Navigation bottleneck in Qingyuan section often causes vessel

block and needs to be resolved within the project as soon as possible.

8.1.3.2 Questionnaire

The statistic data from returned questionnaires are listed in Table8-4. We can briefly conclude

useful information from the returned questionnaire as follows:

Near 70% of people know about the project, but only a small part (10%) know the details;

More than a third people believe that the project will have impacts on water quality (55%),transportation (43%), drinking water security (36%), and local economy (29%);

Over half of the people believe that the project is necessary and for the project;Priority concerns are: drinking water security, navigation safety, fish resource. tourism and

environment damage;

Mitigation measures for water pollution, ecological restoration and compensation for fishery loss

are the priority concerns in the construction phase; and ninety percent of the people expect that the

project will improve their condition.

8.1.4 Changes of TOR after public consultationThe public opinions towards lo this project were accepted in TOR; the public concerns were

included in the content of EIA.

(1) In order to protect the fish resources, the construction within the no-fishing area between the

twp Qingyuan North River Bridges has been cancelled.

(2) In order to protect the water quality wvithout violating the relevant management and regulation

in the water source protection areas, the sediments (mainly sand) dredged from these areas are

going to be sold as construction material or used to construct the spurs.

(3) In order to protect the aquatic and hydrophyte, the recommended project canceled the reef

bombing and the curve cutting work in the Zhigao Dam.

(4) All the dredging sedimenis (mainly pebble and sand) in the project except that in the watersource protection areas are used to refill the groin.
