1. General Instruction

1.1 Project Brief

Cheng County is located in Longnan City of the six parts in southern Gansu Province, and

located in 105°24 '~ 105°57' of east longitude and 33°31'~ 34°02' of north latitude.

The county is east to Hui County, west to Xihe County, southwest to Kang County with

interval of Western Han River, and the southeast is adjacent to the Lueyang County of

Shaanxi Province. The length of north to south is 55 km, the width of east to west is 52 km,

the area is about 1701 km2, the highest elevation within the county is 2377 m, the lowest

elevation is 50 m, and the county is a relatively wide graben basin in West Qinling fold belt.

Cheng County mainly comprises ―One water and three rivers‖, i.e. Western Han River,

Qingni River, Nan River and Luo River, the total water resources of the whole county is

1,276 billion m3, in which the self-produced water is 0.331 billion m3.

The total land area of the county is 1676.54 km2, the total population is 0.2652 million, of

which the agricultural population is 0.218 million people. The benefited area of the project

comprises 3 towns and 38 administrative villages, and the total population thereof is 0.103

million people.

The county town of Cheng County is divided into Hedong District and Hexi District by

taking the East River as the boundary. Hedong District is called as new town, Hexi District

is called as old town, and the south of the Nan River is called as new Nanhe District. The

population of the urban area is about 80,000. according to the ―Urban Master Plan of

Cheng County (2008-2025)‖, the central city comprises Chengguan Town, Paosha Town

and Chenyuan Town; to the recent 2015, the population of the central city planed is

130,000, the construction land area is 13 km2; to the forward 2025, the population is

220,000, and the construction land area is 22 km2; to the forward 2025, Chengnan water

plant, Hedong water plant and Paosha water plant will be built, and the total amount of

urban water supply will be reached to 65,000 m3/d.

At present, Cheng County has two tap water supply units for supplying water to the urban

area, namely County Tap Water Company and Gaofeng Water Supply Company; the

water supply source of County Tap Water Company is the well located in West Bank of

Qingni River in the Chengguan Shunjia Dam, the water of the well belongs to the

quaternary gap sedimentary water and occurs in gravel layer, and the water is mainly

supplied by the water of Qingni River and the atmospheric precipitation; however, the

contents of lead and COD contained in the surface water of Qingni River exceed the

standards of Class IV in the standard of water environmental quality, and due to the

influence of Wenchuan earthquake of Sichuan, the turbidity of the well water in the water

source is increased, odor and floaters are presented, and the health of urban residents is

impacted seriously; the water supply source of Gaofeng Water Supply Company is

Gaofeng water reservoir, and the actual daily water supply capacity of the company is

1000 m3 only as the drainage area of the water reservoir is less than 10 km2 and the

spatial and temporal distribution of precipitation is uneven. According to the survey, the

existing water supply project of the urban area cannot meet the urban water demand.

In order to solve the contradiction of urban water supply, improve water quality, reduce

cost of water supply, achieve the sustainable economic and social development of Cheng

County and improve the physical health of urban residents, the Water Authority of Cheng

County consults with the relevant personnel of the World Bank to build a new urban water

supply dam by means of the loans of the World Bank, and the loan planned is 226.563

million Yuan.

Cheng County Moba gorge water source project is located in the west of the Cheng

County with 11 km, is apart from Paosha Town with 6 km and is located downstream the

Nan River basin; the geographic location of the project is as follows: 33°45' -33°38 ' of

northern latitude and 105°33'55" - 105°37'60" of east longitude, and the project belongs

to Jialing River system upstream the Yangtze River. The content of project construction

comprises project construction and management system and institutional capacity

building. The project construction mainly comprises dams, water intake structures, water

pipelines, and dam roads and etc. The content of management system institutional

capacity building comprises water resources and comprehensive environmental

management projects based on the concepts and methods of integrated river basin

4. Environmental Impact of the Project and Mitigation Measures Summary

4.1 Environmental Impact Assessment

In the implementation process of environmental impact assessment, the layout of the

project, the main environmental protection objectives in surrounding assessment range

and the sensitive points are identified (see the Figure 4.1-1), the possible adverse

environmental impacts caused by the project are as follows:

4.1.1 Impact on the hydrology and sediment

4.1.1.1 Hydrological changes

4.1.1.1.1 Impact on regional water resource

In the Cheng County Moba gorge water supply project, water is stored in a reservoir,

wherein the normal water level of the reservoir is 1092.70 m, the total capacity is1.79

million m3, the backwater length is about 3.5 km, and the designed reference water is

1.651 million m3/a. In running period, the downstream of the dam comprises a diversion

effect river section of 4 km.

4.1.1.1.2 Ecological water of river and mitigation measures

When the reservoir of Moba gorge is completed, the inflow of Nan River over the dam (the

basin area is 248.2 km2) is retained, and the mean runoff of many years is 1.22 million m3

when the reliability is 95%. The ecological water use of the river is calculated according to

the Tennant method recommended by the ―Environmental Impact Assessment

Specification of River Basin Planning‖, in which the ecological water use of Nan River is

the minimum, namely about 10% of the annual average flow as the minimum use of

ecological water, and according to the calculation of the method, the minimum ecological

water use of Nan River is 0.138 m3/s. Thus, the ecological water of the diversion effect

river section is ensured, and the dam should be provided with permanent plug holes while

construction. The plug hole should lower than the water inlet while higher than the flood

discharge sand flushing port, specifically the elevation is 1024 m-1065 m, the discharge

amount is 0.138 m3/s, thereby ensuring the minimum ecological water use of the

diversion effect river section.

4.1.1.1.3 Impact on the diversion effect river section

Due to the abouchement of Nan River from the Fengquan River downstream the dam of 4

km, and the normally annual runoff of the Fengquan River is 2.06 million m3, it can be

determined that the diversion effect river section is 4 km. The section comprises eight

villages, i.e. Zhuanwancun, Ganlushi, Majiaya, Jianjiagou, Xiaozhuang, Zhangjiashan,

Luangoumen and Niujiaya. Zhuanwancun comprises about 900 people or more, Ganlushi

comprises about 1000 people or more, Majiaya comprises about 300 people or more,

Jianjiagou comprises about 350 people or more, Xiaozhuang comprises about 250 people

or more, Zhangjiashan comprises about 600 people or more, Luangoumen comprises

about 100 people or more, and Niujiaya comprises about 120 people or more. The water

of the eight villages is mainly supplied from the local mountain spring and groundwater

which are not the water in the river section, so that the impact of the project to the water

source is controllable.

The ecological water use can be ensured in case of the discharge flow ensured is 0.138

m3/s.

Figure 4.1-1 Location Diagram of Sensitive Points of the Project

4.1.1.2 Impact on Sediment Load and Mitigation Measures

The factor impacts the bedload sediment is more. According to the current technology and

the test means and equipment thereof, the accuracy of the test data is not high, the

relation of push and suspension ratio of the sediment to the various hydrological factors is

bad. In the project, the bedload sediment of the region is designed to the 15% of the

suspended load sediment by combining with the general relation of the mountain stream

push and suspension ratio of 10 to 20%. The annul bedload sediment of the hydrological

station of Cheng County is 133,600 t, the average total sediment load of many years is

1.024 million t, and the average sediment load modulus of many years is 682 t/km2.

According to the calculation, the average suspended load sediment of many years of

Moba gorge dam is about 147,200 t, the annual bedload sediment is about 22,100 t, and

the average total sediment load of many years is 169,000 t.

After completion of the project, the speed of the water floor is reduced, which is conducive

to sediment deposition, and thus sediment deposition speed in the reservoir can be

accelerated. In order to ensure the capacity, the project should discharge sediment to the

downstream irregularly. In the sediment discharge period, the flow of the diversion effect

river section will be increased, the sediment concentration will be increased, but the

impact to the downstream river is in the acceptable range.

4.1.2 Impact on Local Climate

After running of the reservoir, the original undulating land of the submerged area is

replaced by smooth water surface, so that the energy exchange method and intensity

between the underlying surface and the air are changed. As the heat capacity of water is

more than that of the land soil, the temperatures, before and after constructing the

reservoir, of the same point in the submerged are different, the horizontal exchange is

caused due to the temperature difference of land and water, and the temperature of the

land around the reservoir is also changed.

Due to the large-area water storage formed by the construction of the project, the

evaporation capacity is increased and the rainfall is increased; due to the effect of lower

temperature of the reservoir, the distribution of rainfall is changed, the rainfall of the

protected areas over the reservoir and the coastal flow will be reduced, and the rainfall of

the windward slope along the air flow direction will be increased; the underlying surface of

the reservoir region is changed from a land surface into a water surface, and the energy

exchange method and intensity thereof to the air are changed, so that the temperature is

changed, the annual mean temperature is increased slightly, but the regional impact is in

the acceptable range.

4.1.3 Impact on Water Environment and Mitigation Measures

4.1.3.1 Impact of Construction Period on Water Environment and Mitigation

Measures

4.1.3.1.1 Foundation Pit Wastewater Treatment Measures

4.1.3.2 Impact of Operation Period on Water Environment and Mitigation Measures

4.1.3.2.1 Impact on Water Temperature

When the project is completed, the temperature of the water is very different to that of the

Water inlet

Water outlet

natural river before constructing. The change of the water temperature will influence the

vertical structure of the reservoir, so as to form water temperature stratification, according

to the determination based on runoff-storage capacity ratio method, alpha=2.52, the

reservoir is a stable layered reservoir; beta=0.2, and the impact of flood to the water

temperature structure is basically free.

4.1.3.2.2 Impact on Water Quality and Mitigation Measures

According to the survey, the upstream of the reservoir has a lead-zinc concentrator, a gold

concentrator and a gold ore mine. The two concentrators has been closed by the

Environmental Protection Bureau of Cheng County, and the gold ore mine will be closed

down soon.

In addition, the ambitus of the reservoir does not have pollution and industrial pollution

enterprises, when the concentrators and the gold ore mine are closed, the impact on the

water quality of the reservoir is mainly caused by regional soil and water loss and the

organic matters of part soil are entered into the reservoir together with the sediment, so

that the sediment in the reservoir is increased, and the contents of nitrogen and

phosphorus are increased. However, the generation is relatively small, and the water

quality of the reservoir will not be impacted basically; in order to ensure the water quality

of the reservoir, the following measures should be taken when the project is completed, so

as to prevent the impact of unexpected incidents on the water quality:

(1) Strengthen water quality monitoring the reservoir area, complete the cleaning work

well, and regularly fish the floating material on the water surface of the reservoir.

(2) Draw a certain range with clear boundary as the water source protection area on the

upper and lower basins of the water intake port and the deep land-based area, protect

strictly, take practical and effective measures, and prevent water pollution.

(3) In order to ensure standard discharge of the water source, the ―Moba gorge water

source protection regulations‖ must be developed according to the relevant laws and

regulations of the Country and Longnan City, so as to protect the water source effectively.

(4) Strengthen natural vegetation protection and ecological construction, prohibit

deforestation, protect natural vegetation and water source conservation, and reduce water

loss and soil erosion.

(1) When the ―Moba gorge water supply project is completed, the water source

engineering construction management department of Moba gorge for city water supply of

Cheng County should divide a drinking water source protection area according to the

requirements of ―Pollution Control Management Regulations of Drinking Water Source

Protection Area‖ and manage by complying with the regulations completely.

① First-grade Protection Area

Prohibit new construction and extension of the construction projects which are not related

to the water supply facilities and water sources protection, prohibit the discharge to the

basin, and remove the discharge port;

Prohibit the wharf which is not related to the water supply requirements, and prohibit

vessel callings;

Prohibit the industrial waste, municipal waste, manure and other wastes from stacking and

storing;

Prohibit the construction of oil depot;

Prohibit from engaging in cultivation and livestock restocking, and strictly control cage

culture activities;

Prohibit the tourist activities and other activities which may pollute the water source.

② Second-grade Protection Area

Prohibit new construction and extension of the construction projects for discharging

pollutant to the water. The discharge of pollutant in the reconstruction project must be

reduced, the wastewater discharge of the original discharge port must be reduced, and

the water quality in the protection area must be in line with the water quality standards

provided;

Prohibit the construction of the wharf for loading/unloading garbage, manure, oil and toxic

substances.

③ Quasi-protection Area

Wastewater directly or indirectly discharged to the basin must be in line with the national

and regional wastewater discharge standards. When the total discharge amount of the

protection area cannot be in line with the standards provided, the discharge load must be

reduced.

(2) The water source engineering construction management department of Moba gorge

for city water supply of Cheng County should compile an ―Environment Protection Plan of

Drinking Water Source of Cheng County‖ according to the ―Compilation Technical

Specifications of the ‘Environment Protection Plan of National Drinking Water Source‘‖

(May 2006).

(3) Strengthen the construction of water conservation area. In the protection area of Moba

gorge water source, the vegetation construction should be strengthened, the forestation

should be strengthened, the damage to the vegetation cover should be reduced, the forest

coverage should be improved, and the ecological water source should be protected.

(4) Strengthen the use management of farmland pesticide and fertilizer in the protection

area. As the upstream of the Moba gorge water source has part of plantation, the

large-scale use of pesticide and fertilizer will be entered into the surface water bodies

together with the rainwater, so that the ammonia nitrogen, nitrate nitrogen and nitrite

nitrogen in the water quality of water source are obviously exceeded the standards, which

not only affect the water quality of the reservoir, but also affect people's health directly.

Thus, the use of pesticide and fertilizer must be strengthened, and the agricultural

non-point pollution should be reduced.

(5) Order to close the two concentrators upstream the reservoir, and close the gold ore

mine, treat the remaining issues, and develop perfect emergency plan.

(6) Strengthen water quality monitoring of water source

4.1.3.2.4 Impact for Domestic Wastewater of Management Station and Mitigation

Measures

The wastewater discharged in the operation period mainly comprises the domestic

wastewater of managerial personnel of the management station, wherein the fixed staff of

the management station is 35 people, the maximum water consumption of the production

and living area is about 3.5 m3/d on the basis of 100L/person/d. Accordingly, the domestic

wastewater discharge is about 3.3 m3/d. In order to ensure that the pollution of the water

source caused by the domestic wastewater generated by the managerial personnel of the

management station is prevented from is prevented, the WSZ buried wastewater

treatment equipment is recommended to treat the domestic wastewater generated by the

managerial personnel, wherein the specific process is shown in Figure 4.1-4. After treating

by the equipment, the discharge concentrations of CODcr, BOD5 and SS are 60 mg/L,

30 mg/L and 60 mg/L, respectively; so that the first-grade standard in the ―Integrated

Wastewater Discharge Standard" (GB8978-1996) can be met, the domestic wastewater

treated is used as the surrounding green water, and the sludge settled is used as

agricultural fertilizer. See the Table 4.1-2 for the effects of WSZ buried wastewater

treatment equipment.

4.1.4 Impact on Atmospheric Environment and Mitigation Measures

In the project, the atmospheric pollutant is mainly generated in construction period, the

atmospheric pollution of operation period is basically free, and the impact on atmospheric

environment and the mitigation measures are target to the construction period.

4.1.4.1 Construction Dust Impacts and Mitigation Measures

Construction dust mainly comprises transport vehicles dust, natural wind dust, ground

building materials stacking yard dust and construction process dust. In order to reduce the

impact of dust on the environment and the construction workers, the following mitigation

measures should be taken:

(1) In the construction process, the construction site will be provided with blocks and

envelope to reduce dust diffusion, the block and envelope play a significant role in

reducing the pollution of the dust to the environment; when the wind speed is 2.5 m/s, the

impact distance can be shortened by 40%. The surrounding space of the construction site

is continuously equipped with the blocks of less than 2.5 m, and the blocks are firm and

beautiful;

(2) Assign the staff to water the construction site regularly to reduce dust emission on the

construction site, wherein the time of watering is determined according to the weather,

wherein the general frequency is 1 to 2 times per day, and the time can be appropriately

increased in case of high wind or dry weather. The impact of watering operation on the

construction site is large to the dust; after watering the dust can be reduced by 28 to 75%,

and therefore the impact of the dust on the environment is reduced greatly;

(3) Set a tarpaulin on the vehicle for transporting the building materials and the

construction waste to reduce scatter. At the same time, the tires of the vehicle should be

cleaned with water while accessing the site and loading and unloading on the site, and the

traffic route of the vehicle should be prevented from the residential areas as much as

possible.

(4) In the application of commercial concrete, the construction work of windy weather

should be prevented as much as possible. At present, it is determined that the earthwork

and stonework construction is prohibited in wind of Category 4, the project can learn from

the provision;

(5) Assign a specially-assigned person who is specifically in charge of the treatment,

cleaning and stacking of spoil, construction waste and building material on the

construction site, wherein the stacking yard should be provided with a cloth cover or

watered to prevent secondary dust;

(6) The construction waste and spoil should be treated and cleaned in time, so as to

reduce the space, prevent dust pollution, and improve the environment of construction

site;

(7) In the mechanical excavation process in the tunnel, the intermittent operation method

is used, the ventilation should be in time, and the construction worker should wear a mask,

if necessary.

4.1.4.2 Exhaust Gas Environmental Impact and Mitigation Measures

In the construction process, the fuel exhaust gas generated by the construction machinery

and the transport vehicles mainly comprises CO, NOx and THC. The total amount of the

fuel consumed by the project is 1663.4 t, and the discharge of each pollutant is as follows:

CO is 148.1 t, NOx is 95.78 t and THC is 27.5 t; the tail gas discharge port of the fuel

machine is low, and the discharge belongs to low-point source disorder discharge, and the

discharge mainly in the range of 100 m in relation to the discharge source. In the project,

the environmental sensitive points in the range of 100 m in relation to the construction

area are free, and the discharge mainly impacts the construction area. The impact of the

transport vehicles on the environment along the route in the transportation process is

relatively small.

In order to mitigate the impact of exhaust gas on the environment, the management of

large-scale fuel construction machinery and vehicles should be strengthened, the regular

inspection and maintenance system should be implemented, and all the tail gas discharge

of fuel machinery and vehicles of the contractor should implemented according to the

―Automobile Air Pollutants Discharge Standards‖, and the smoke and dust removal

equipment must be provided in case of the purpose of standard discharge cannot be

achieved. The construction machinery uses unleaded gasoline and other high-quality

fuels. Strictly implement ―In-use Vehicle Rejection Standards‖, implement a mandatory

retirement and update system, and update the old vehicle with more engine fuel

consumption, low efficiency and seriously excessive exhaust gas discharge.

4.1.5 Impact on Acoustic Environment and Mitigation Measures

The noise impact of the project is mainly presented in the construction period, the noise

impact of the operation period on the environment is relatively small, so that the impact on

acoustic environment and mitigation measures are mainly targeted to the construction

period.

The construction machinery used in the project mainly comprises rock drilling machines,

bulldozers, excavators, mixers and drills and etc., and the noise source will have some

impact on the surrounding acoustic environment without taking measures. The acoustic

pressure level is shown in Table 4.1-3, and the prediction results are shown in Table 4.1-4.

With analysis, the following conclusions can be obtained:

(1) In case of the use of single construction machinery, the ―Noise Limit of Construction

Site Boundary‖ GB12523-90 can be achieve in the place apart from the construction site

with 75 m at daytime, and the standard limit can be achieve in the place apart from the

construction site with 1250 m at nighttime. But in the actual construction process, variety

of machines are always used simultaneously, the noise impact will be greater than the

scope;

(2) In the range with the distance about 5-35 m to the construction site boundary, the

impact of construction noise on the surrounding acoustic environment is relatively large;

(3) With the completion of the project, the construction noise will no longer exist, so that

the adverse impact of construction noise on the environment is temporary and short-term.

In order to mitigate the impact of noise in the construction period, the following mitigation

measures should be taken:

(1) Control from the acoustic source: construction units should require the main

mechanical equipment used by the construction unit is low-noise mechanical equipment

while signing the contract with the construction unit, meanwhile, the construction unit

should appoint a specially-assigned person to regularly maintain and service the

equipment in the construction process, and the construction unit should be responsible for

training the on-site staff so as to use the various machines by complying with the

operation specifications strictly. Reasonably arrange the service time of hammers, air

hammers and rock drill machine and other high-noise construction machinery, reasonably

arrange blasting time, and reduce the noise generated by the equipment in the abnormal

operation process. As the distance of Majiaya construction site to the Majiaya is 400 mm,

the distance of Xiaozhuang construction site to the Xiaozhuang is 650 m, the nighttime

construction will have a greater impact on them, so that the high-noise construction

machinery (such as rock drilling machine and drill) should be prohibited from night

construction.

(2) In the structure stage of construction, the exterior of the building should be equipped

with a block, so as to reduce the impact of equipment noise on the surrounding

environment.

(3) Personal protective measures of construction workers: strengthen labor protection,

and improve workers' working conditions. For the construction workers in the high-noise

environment of the first production line, the consecutive working hours per day should not

be more than 6 h; the construction workers with large noise impact should be provided

with noise protective equipment; and the workers on the construction site should wear

anti-noise cotton to reduce the impact of noise.

4.1.6 Impact of Solid Waste on Environment and Mitigation Measures Thereof

4.1.6.1 Impact of Solid Waste of Construction Period on Environment and Mitigation

Measures Thereof

4.1.6.1.1 Impact of Construction Waste and Vegetation Cleaning on Environment

and Mitigation Measures

Reference to the ―Technical Specification for Cleaning Solid Waste on the Bottom of Three

Gorges Reservoir" and the requirement of water source protection, the vegetation and the

construction waste of submerged area in the project should be cleaned. According to the

estimation, the vegetation to be cleaned is about 50,000 m3, and the construction waste

cleaned is about 14.13 t. The part of the vegetation cleaned further can be restored, and

the optional stacking of the vegetation not only has impact on the environment, but also

wastes resources. The vegetation which can be restored is recommended to be given the

farmers of the surrounding villages, and the vegetation which cannot be restored is

transported to the landfill site of Cheng County. The construction waste cleaned is

transported to the residues place of the project.

4.1.6.1.2 Impact of Household Wastes of Construction Workers on Environment and

Mitigation Measures

As the huge quantities of the project, the construction workers are more, the random

storage of a lot of household wastes not only pollute the environment, but also easy to

breed mosquitoes, which is harmful to human health. In order to mitigate the

environmental impact of household wastes, each construction site should be equipped

with two garbage cans, and the total number of the garbage can in the construction site is

28. The household wastes are uniformly stored in a sealed garbage can, regularly

collected by a special car and subsequently transported to the landfill site of Cheng

County to landfill.

4.1.6.2 Impact of Solid Waste of Operation Period on Environment and Mitigation

Measures

When the project is completed, the total establishment determined of the operation

management personnel is 35 people. The household waste generated by each person per

day is 0.8 kg, and the household waste generated by the 35 people per year is 10.22 t. In

order to prevent the impact of household waste on the surrounding environment, the

management station is provided with 2 garbage cans to collect that, and the household

waste will be regularly transported to the landfill site of Cheng County to implement

centralized treatment.

4.1.7 Impact of Environmental Geology and Mitigation Measures

The dam area of Moba gorge water source project and the neighborhoods belong to

east-west Qinling tectonic system and the composite part on the east of the Wudu epsilon

structural system, the project is located in the northwest edge of the emblem basin. Both

the north and south sides are composed of a series of curved folds and fractures of SWW

~ NEE direction. In the early Quaternary Pleistocene, the area also belongs to the general

uplift phase of Qinghai-Tibet Plateau due to the impact of movement of the Himalaya, and

accretion of 10 to 50 m thick of the Quaternary system is accumulated in the area.

In the project area, the movement of the new construction is relatively active, and the

movement mainly comprises differential uplift and subsidence, the movement is more

prominent in the Quaternary; the valley terrace is developed, and the more active

fractures are developed in the periphery of the project area. In the range of the project

area, the active fracture is free, and the construction site is in a relatively stable tectonic

area. The acceleration of peak ground motion of the construction site is 0.20 g, the basic

earthquake intensity is VIII degree, and the ground motion response spectrum

characteristic period is 0.40s. The distance of the latest active fracture to the dam is 6 km.

In order to mitigate the impact of environmental geological disasters on the project, the

purpose of protecting geological environment and preventing and reducing the loss of

geological disasters should be achieved according to the principle of "prevention first,

combining prevention with control", and the following recommendations of control

measures are provided for the various types of geological disasters:

(1) For the collapse of fat rock and soil and caving and other geological disasters which

may be presented while excavating the abutment construction, temporary support or

temporary bracing and other measures can be taken to ensure the security and stability of

abutment construction, and the surface and groundwater discharge work should be

simultaneously completed well.

(2) For the collapse and caving-in and other geological disasters of slope break and

weathered sediment layer which may be presented while excavating the inlet of the water

tunnel, the outlet slope and the construction, temporary support or temporary bracing and

other measures can be taken while combining with the permanent slope protection

measures of the hole face slope, so as to ensure the security and stability of construction

and operation, and the discharge and guide work of surface and groundwater should be

simultaneously completed well.

(3) When the tunnel through the broken belt or soft interlayer, the stability of surrounding

rock is poor, the collapse, roof collapse and other geological disasters may be caused, the

support should be provided in time while excavating, the support should be provided while

excavating, and the waterproofing work of the tunnel should be made well.

(4) For the lateral sliding of foundation pit geotechnical slope and collapse and other

geological disasters which may be presented in the excavation process of dam foundation,

temporary support or temporary bracing and other measures can be taken, the high slope

formed after excavation should be shown in the form of cascade slope, so as to ensure

the safety of the foundation pit slope in the construction period.

(5) The earthwork and stonework construction should be subjected to the operating for

filling with the excavation as far as possible, so that the unstable slope caused by stacking

the residues can be reduced, the residues must be stacked should be provided with

corresponding protective measures.

4.1.8 Impact on Ecological Environment and Mitigation Measures

4.1.8.1 Impact on Terrestrial Animals and Mitigation Measures

4.1.8.1.1 Impact of Construction Period on Terrestrial Animals and Mitigation

Measures

(1) Impact on mammals

The interference of construction activities of the project to the mammals mainly in the hub,

plant and tunnel construction areas, the impact on the mammals mainly comprises the

drive of construction activities and construction noise to the mammals, namely the

animals fled to other places after frightening, and the food debris and wastes left behind

by human activity will attract rodents (mice) gather in the construction area. As mammals

will avoid the harm caused by the project construction by means of migration, the total

direct impact of the project construction to the mammals is small. With the completion of

the construction activities and the restoration of the construction site and the nearby

natural ecological environment, the animals will return to the original project area, so that

the long-term impact of the project on the mammals is small.

(2) Impact on birds

The construction activities will cause disturbance and destruction in the habitat of the bird,

so that the habitat of the bird will be directly or indirectly destroyed, the nests will be

damaged, and the bird habitat in the shrub niche will be disturbed. Due to theses impacts,

most of the birds will migrate to other places far from the construction site, and a small

part of the bird with shrubs and forest-dwelling habitat will disappear from the project area

due to the loss of the habitat; a part of the bird populations will be reduced as the nest

destruction, particularly the construction period is in the bird breeding season (summer).

The overall result is that the species and number of the bird in the project range are

reduced. Since most birds will fly and make a short-distance migration to avoid the harm

caused by the construction project, the impact of the project construction on the bird is

small. The main indirection impact is the reduction of the foods such as rodents of the

birds in the project area caused by the construction interference, thereby forcing the birds

to prey in a greater range. With the completion of the construction activities and the

restoration of the line construction site and the nearby natural ecological environment, the

birds in the project area will return to the project area, so that the long-term of the project

on the birds is small.

In order to ease the impact of construction period on the terrestrial organisms, the

education of ecological protection to the construction workers should be strengthened by

means of notice, dissemination of brochures and other methods in the construction period

of the project, the construction workers are strictly prevented from cutting the trees,

outside the construction site, without permission by means of institutionalization, and the

construction workers are prohibited from preying frogs, birds and snakes and other wild

animals. The Majiaya Qiaotou construction site of the left bank, the construction site

upstream the dam of left bank, the Xiaozhuang-Gumugou construction site of right bank,

the dam construction site between the cofferdams, the construction site upstream the dam

of right bank and water pipeline construction site and other sites are provided with 1 to 2

blocks of terrestrial vegetation and wildlife protection warning signs, and the total number

of the warning sign is 15 blocks. The warning signs are thin steel plates with blue bottom

and white words, the specification of the warning sign is 100 cm x 60 cm, (length x width),

and the warning sign has the words of prohibiting vegetation destruction and wildlife

hunting.

The operation mode and time of the construction machinery should be reasonably

arrange, the construction mechanical equipment should be the mechanical equipment

with low acoustic level, and the time of whistle of the transport vehicle should be reduced,

so as to reduce the disturbance of construction noise to the wildlife.

4.1.8.1.2 Impact of Operation Period on Terrestrial Animals and Mitigation Measures

When the project is completed, the impact of the project on the local animals will not be

significant while ensuring the discharge ecological water use. The habitat of the wildlife at

the reservoir area will not be reduced as the water storage of the project, and the project

will impact some species of the reservoir area; however, the impact is short, and the new

habitat environment can be formed after a period of time, so that the impact of the project

on the local wildlife is in an acceptable range. The damage of variety of vegetation and

habitat types caused by the construction should be gradually restored by implementing

ecological restoration measures in the operation period, and the wildlife habitat can be

partially restored.

4.1.8.2 Impact on Aquatic Life and Mitigation Measures

According to the ―Aquatic Life Status Monitoring of Environmental Impact Assessment of

Cheng County Moba Gorge Water Source Engineering of Gansu Province and Apecial

Report of Assessment‖ provided by the Fengyuan ecological counseling center of Gansu,

the following analysis is provided:

(1) Impact on fish and mitigation measures

The construction of the project will change the position for the spawning ground and the

wintering ground of Schizothorax subfamily in a short time, but due to the Schizothorax

fish will soon find a new wintering ground and spawning ground as the same habitat

upstream, so that the wintering and spawning process can be carried out. When the new

wintering ground and spawning ground are found, the impact of the project is free. Thus,

the impact of the project on the wintering and spawning of the Schizothorax fish is free

while ensuring the discharge water.

In order to mitigate the impact of the project on aquatic life, following measures should be

taken:

① The most basic discharge flow for the growth, reproduction, habitat and wintering and

other survival conditions of the aquatic life (especially fish) must be ensured, particularly

the discharge should be increased in fish breeding and wintering season.

② Effectively implement the spirit of ―Chinese Aquatic Resource Conservation Platform

for Action‖, implement the aquatic organisms maintenance system of "who develops

protection, who benefits compensation, who damages restoration", and ensure the

on-time and in-full funds for the various funds of aquatic life resources, particularly for

the germplasm resources communication and aquatic biological monitoring.

③ The owners should increase the propaganda of the relevant laws and regulations for

the protection of aquatic organisms, strictly crack down the illegal practices of poison

fishing, electric fish, catch fish and excessive catch by coordinating the local fishery

agencies, and resolutely implement the spirit for the notice of natural waters banned of

Gansu Province, so as to ensure sustainable development of fish resources, and

long-term use purpose.

④ Purchase Jialing Schizopygopsis Tajiri Schizothorax fish artificially bred to implement

discharge proliferation. When the water project is finished and run, the discharge cycle is

three years, the amount thereof is 2000 Jialing Schizopygopsis Tajiri Schizothorax fishes

with the size of 3 to 4 cm, the discharge is a long-term work, and the discharge fees are

included in the operation costs.

(2) Impact on plankton

After the completion of the dam, a reservoir of water is formed, and lots of land and

vegetation are flooded; due to the nutrient leached from the flooded soil, the organic

matter provided by the decomposition of flooded plants and the scouring effect of the

runoff to the surface, a number of nutrients are provided for the growth of algae. At the

same time, the growth of algae is convenient as the speed of water flow is reduced, the

transparency is improved, and the algal blooms can be promoted. However, when

phytoplankton blooms, the transparency of the water is reduced, the optical radiation

condition of the water is changed, and the phytoplankton in the reservoir is stabilized after

a period of time, so as to reach to a new dynamic equilibrium of algae number.

The zooplankton of the reservoir mainly comprises rotifers, cladocerans and copepods.

The existing volume and production level of the zooplankton are the impact on the existing

volume and production capacity of algae, bacteria and other microorganisms, and the

zooplankton is another biological resource in the water reservoir. The change for the

geographical position, climate, water temperature and water level of the reservoir are

closely related to the reproduction of the zooplankton.

(3) Impact on zoobenthos

The initial stage when the project is completed, the sediment is deposited on the upstream

of the dam, the water surface is expanded, the types of zooplankton, the number of

individuals and biomass are increased and improved, a good growing environment and

food source are provided to the zoobenthos, so that the biomass and the density of the

zoobenthos will be increased, and a rich food source is provided for many indigenous

fishes; but as time goes on, the silt layer is thickened, the living environment of the

zoobenthos is damaged, and there are some negative impacts on the growth and

reproduction of the zoobenthos. If the normal ecological discharge downstream the dam is

ensured, the adverse impacts to the zoobenthos are basically free.

4.1.8.3 Impact on Terrestrial Plant

In the permanent land of the project, the occupation land of forest is 57.91 hm2 and the

occupation land of cultivation is 15.33 hm2; according to the statistics of Cheng County,

the local annual production of forest land per hectare is 3200 kg, the annual output of

arable land per hectare is 2746.83 kg, the loss of the project to the local biomass is 234.37

t/a, and the details are shown in Table 4.1-5.

The basin area upstream the Moba gorge of Nan River is 248.2 km, the agricultural

acreage is 3133.3 hm2, the forest area is 17133.3 hm2, grassland is 1800 hm2, and the

vegetation coverage in the area is 69%. Although the project will have some impacts on

the local plant, the impact on the plant of the whole area is in the acceptable range.

4.1.8.4 Impact on Whole Ecological Environment of the Area

According to the existing data and the site investigation, the assessment range of Cheng

County Moba gorge water source engineering is 1200 hm2. According to the calculation

method provided in the ―Technical Regulations of Ecological Environment Status

Assessment (Trail)‖ (HJ/T192-2006), the reference to the comprehensive evaluation for

the ecological environmental quality of Nantong City provided by Shen Weimin and

Qianzhen and others, the study for the environmental quality evaluation of Minjiang River

provided by Zheng Shujuan and the combination of satellite remote sensing data, it can

be obtained that the ecological quality index EI before completing the project is 61.89, and

the ecological quality index EI after completing the project is 61.69, and both the indexes

are good eco-environmental quality evaluation; the absolute value of delta EI is 0.2 <2, so

that it can be proved that the environmental quality before and after the project

construction has no significant change.

4.1.9.4 Residues Place Overview and Rationality Analysis

The project is primarily provided with 5 residues places, wherein the 1 # and the 2 #

residues places are located in the construction site upstream the dam of left bank, the 3 #

residues place is located in the construction site upstream the dam of right bank, and the

4 # and the 5 # residues places are located in the Xiaozhuang-Gumugou construction site

of right bank. 1 # residues place: the final elevation of the residues place is 1060 m, the

land area is 21000 m2; 2 # residues place: the final elevation of the residues place is 1060

m, the land area is 18000 m2; 3 # residues place: the final elevation of the residues place

is 1056 m, the land area is 5000 m2; 4 # residues place: the final elevation of the residues

place is 1165 m, the land area is 13000 m2; and 5 # residues place: the final elevation of

the residues place is 1050 m, the land area is 52000 m2. As the residues of the project are

mainly generated by the dam excavation and the primary residues places are too

fragmented, the spoil of the dam is respectively sent to four residues places, and the

earthwork allocation is unreasonable; after the optimization of the environment impact

assessment, the primary 1 # and 2 # residues places are combined, the area is increased,

and the optimized residues place is used as the 1 # residues place; the primary 3 #

residues place is removed, the primary 4 # residues place is used as the 2 # residues

place after optimization and the area thereof is maintained, the area of the primary 5 #

residues place is reduced, descended to the height of the residues and used as the 3 #

after optimization. The details are shown in Table 4.1-8.

After optimization, the influence area of the residues place does not have the distribution

of rare wild animals and plants, and the surrounding places of the residues place do not

have residents; from an environmental point of view, the selection scheme of the residues

place is reasonable. However, the residues should be protected in the stacking process,

so as to reduce water loss and soil erosion.

4.1.9.5 Amount of Water Loss and Soil Erosion and Mitigation Measures

The total amount of water loss and soil erosion of the project is 18645.96 t, and the

increased amount of water loss and soil erosion is 13342.71 t, wherein the increased

amount of water loss and soil erosion in the construction period is 12609.27 t, and the

increased amount of water loss and soil erosion in the natural recovery is 12.52 hm2. The

division of water loss and soil erosion control is as follows: a dam hub building control

area, a water pipeline control area, a residues place control area, a quarry control area, a

road construction control area, and a construction enterprise and office and living control

area. The soil and water conservation measures comprise 1640 m of slag wall, 1800 m of

reinforced stone block, 600 m of dry stone pitching, 25140 m of drainage ditch, 2340 m of

bag soil block, 96959 plants, 116 linear meters (the width is 1 m) of holly hedges, 4477 kg

of grass seed, 21.88 hm2 of land reclamation, 17.16 hm2 of green space, and the detailed

layout program is shown in Table 4.1-9.

When the soil and water conservation program is implemented, the control rate of the

disturbed ground in the early construction period is 98.67%, the control degree of water

loss and soil erosion is 98.07%, block slag rate is 100%, the control ratio of water loss and

soil erosion is 1.03, the vegetation restoration rate is 98.76%, the restore coverage is

41.3%, wherein all the indexes are reached to the, and the water conservation measures

are reasonable and reasonable.

4.1.10 Impact on Human Health and Mitigation Measures

4.1.10.1 Impact of Construction Period on Human Health and Mitigation Measures

The construction workers for the construction period of the project are from all sides, and

the field personnel and local personnel form a construction community and frequently

contact with each other in working and living. As the crowd is complex, the lifestyle is

different, the physical conditions are different, the immunity is different, the kinds of

pathogen carriers are possible, the susceptibility is enhanced, and a variety of diseases

transmission method are coexistent. Thus, if the health protection work cannot be

completed well, the infectious diseases can be lead (gastrointestinal, respiratory, and

insect-borne), the cross-infection and epidemic spread are easy to be caused, the

adverse impact on human health will be caused, so that the health protection work should

be paid enough attention.

In order to mitigate the impact of construction period on the construction workers, and the

following measures should be taken:

(1) Hygienic cleaning of construction living area and management area

When the civil engineering works of the temporary construction living area and the

management area are completed, the site should be cleaned. The garbage, human and

animal feces and other contaminants in the site should be cleaned; the sewage pit and the

refuse dump should be filled after sterilizing with lime, and the weeds should be cleaned

up.

(2) Drinking water source protection and drinking water disinfection

The drinking water is purified and disinfected, wherein the specific methods are as follows:

adding bleaching powder into the drinking water to disinfect after depositing and filtering,

adding chlorine into the water for 30 min, so that the killing effect to the variety of intestinal

infectious disease pathogens in the water is sufficient when the residual chlorine in the

water is more than 0.3 mg/l, and the water purified can be used as drinking water.

As the construction and living water is taken from the river and the water source is open,

the water quality is easy to be impacted by the human actives around the construction site,

so that the protection of the water source should be strengthened, and the protection

measures are as follows: the range which is apart from the water source with 100 m

should not be provided with temporary life area, management area and production area,

and the latrines and seepage pits should be built in the range, and the garbage and other

pollutants should not be stacked in the site.

(3) Innocent treatment of garbage, manure and wastewater

With the collection and treatment facilities arranged on the living area, management area

and production area and applied to domestic wastewater, production wastewater and

household waste and the like, the innocent treatment purposes of garbage, manure and

wastewater are basically carried out.

(4) Mosquito prevention, fly disinfestation and rodent control

When the construction workers are entered into the site, a good breeding ground will be

provided to a variety of animals and insects in case of poor sanitation, the density of

mosquitoes and rodents and the like will be improved, and the opportunity of infectious

diseases will be increased. Thus, the living area should be subjected into mosquito

prevention, fly disinfestation and rodent control, the rodent prevention drugs should be

provided regularly so as to cut off the disease source the transmission method.

(5) Prevention and quarantine of population health

Before entering into the construction site, all the dining room staff of the construction site

should be quarantine, part of the construction worker should be subjected to prevention

and quarantine by means of a sampling method, wherein the sampling ratio thereof is

15% of the construction workers. Through quarantine, the health status of the construction

population can be controlled, and the occurrence of contagious disease in which the

construction worker is the epidemic focus can be completely eradicated in time.

(6) Crowd evacuation of blasting site

The use of explosive on the blasting site is operated by a specially-assigned person, the

places around the blasting site are provided with striped flags so as to define the risk area,

and all the personnel in the blasting area should be evacuated, so that the casualties

caused by blasting can be prevented.

4.1.10.2 Impact of Operation Period on Human Health

As the river valley of the project is mainly shown in the form of a "U"-shaped valley, the

mountains of the two banks are relatively symmetric, the river is deep, the bedrock of the

riverbed is exposed, the falling head is large, and the submerged area does not have

large-scale unleveled low-lying land and pond marshy with aquatic weeds and etc., and

therefore the submergence for the operation period of the project will not cause the

transfer of mosquitoes and the transmission of pathogenesis.

4.1.11 Impact on Reservoir Resettlement and Mitigation Measures

The backwater length for the reservoir of the project is 3.5 km, the area of the submerged

land is 53.85 km2, wherein in the land, the forest is 45.13 km2, the plantation is 7.45 km2

and the unused land is 1.27 hm2. The submerged area of the reservoir mainly comprises

three towns, i.e. Shaba Town, Paosha Town and Chenyuan Town, part area of 6

administrative villages, and the total immigrants thereof is 3 families.

In allusion to the special resettlement and compensation problems, the Water Authority of

Cheng County develops ―Resettlement Plan of Water Source Project of Cheng County‖,

the resettlement point is located in Baimashi Village of Chenyuan Town of Cheng County,

wherein the distance of the village to the county is 6 km, the village comprises 8

cooperations, the existing residents is 391, the population is 1,600, the acreage under

cultivation of the total village is 2800 Mu, and the net per capita income is 2200 Yuan/year.

The distance of the village to the nearest road is about 0.5 km, so that the traffic is

convenient. The distance to the post office, shops, schools, kindergartens, theaters and

other places is about 1 km. The agricultural products produced therein mainly comprise

wheat, corn, soybeans, canola and tobacco and etc. The settlement point planned

comprises 20 rooms reconstructed from original farm buildings, the land area thereof is

13.5 Mu, the settlement point has a campus testing field of 76 Mu, wherein the irrigation

project thereof is the Lugou reservoir water-saving irrigation project which has been

implemented, the requirements of three families to the relocated of Chenyuan Town and

Shaba Town can be met, and the irrigable land per capita ensured is about 2 Mu.

The compensation measures for the resettlement are in line with the principle of ―ensuring

the ‗feasible moving, stable settling, and feasible enriching‘ of the migrants‖, and the

compensation measures are reasonable and feasible; the resettlement point has

adequate houses for the live of the immigrants, sufficient arable land and good irrigation

conditions to ensure the living and production need of the immigrants; the resettlement

point has relatively complete municipal facilities, convenient transportation, and favorable

new life of the migrants, and the resettlement point can meet the requirements of the

resettlement compensation plan.

4.1.12 Dam Break Risk and Mitigation Measures

4.1.12.1 Dam Break Risk

According to the research results for the dam safety at home and abroad, the reason for

causing the dam break and the break is more and complex, and the reason comprises

natural factors and human factors and their mutual relations and complex effects. With the

probably analysis, the main reason comprises:

(1) Violent earthquake

Small earthquakes are not likely to cause the damage and break of the reservoir dam, but

a strong earthquake (magnitude is not less than 7.0) is more likely to cause the damage

and break of the reservoir dam. As the earthcrust of the place where the reservoir dam is

located is relatively stable, the basic seismic intensity is grade VIII, the earthquake

fortification of the reservoir dam project is implemented according to the same;

furthermore, the reservoir is small (the height of the dam is less than 100), and the

earthquake cannot be induced easily, so that the possibility for the large-scale and

high-intensity damage of the reservoir dam caused by the earthquake is very unlikely.

(2) Temperature change

The local damage accident for the concrete arch dam of the reservoir dam due to the

temperature change is relatively common, the reason thereof is the thickness of the arch

dam is relatively thin, and the arch dam is a highly indeterminate space structure limited

by the boundaries. In the operation period of the reservoir dam, the change of the ambient

temperature is easy in causing temperature stress in the arch dam body, and the reservoir

dam will be broken as the overstressing in certain conditions. However, the temperature

change just can cause the local damage of the reservoir dam under normal circumstances,

and the suddenly break of the dam can be prevented.

(3) Landslides

Large-scale instability and high-potential fast slope body will cause enormous swell, the

flood downstream the reservoir dam and around the reservoir will be caused, and safety

of the reservoir is endangered. Particularly, the large-scale landslides in the place close to

the dam and the two sides upstream and downstream are easy to cause reservoir

damage and break. Although the project has small-scale hidden danger of slope instability,

the total geological conditions of the reservoir area, the dam and the site engineering are

relatively good as the diastrophic activity of the place where the project is located are

relatively stable, so that the possibility for causing huge surge flood and collapse due to

the large-scale instability of the bank and the high-potential landslide is very unlikely. Here,

it must be emphasized that the many small-scale instable geologic bodies presented in

the slops on the two sides of the river section inside and outside the reservoir area should

be strengthened, prevented and subjected to the treatment of embankment and

supporting project, so as to prevent the large-scale reservoir banks instability caused by

the small-scale reservoir instability can be prevented. In addition, the operation period for

putting into production of the reservoir dam, the stone blasting and fish blasting and other

blasting activities in the place close to the dam and around the dam should be prevented,

and the a large number of materials optionally stacked on the slops of two banks on the

place of the reservoir area and the place close to the river downstream the dam should be

prevented, and the buildings on the places should be prevented to avoid slump.

(4) Destruction of dam foundation

The deformation, permeability and stability of the dam foundation are tightly related to the

safety of the dam. The good dam foundation should have sufficient deformation resistance

and bearing capacity, small permeability and complete and stable rock, so as to prevent

the foundation damage caused by excessive deformation, the excessive uplift pressure

and the unstable dam body or dam seat rock slide caused by excessive penetration water

pressure. The dam foundation of the project can be prevented from the collapse accident

caused by instability and deformation, cracking, sliding and water seepage just be

strengthening and stabilizing to eliminate the hidden troubles completely through a

scientific project processing technology and strict consolidation prevention measures,

(6) War and terrorist attacks

If the reservoir dam of the project is damaged instantaneously in case of war and terrorist

attacks, the flood damage is severe, and the basin-wide disaster may be caused.

However, from the military point of view, the possibility for taking the dam as a military

target is very unlikely.

(7) Extraordinary flood

In case of extraordinary flood, the extraordinary flood is always accompanied by heavy

rain. Due to the strong erosion effect of the heavy rain, the downstream dam surface will

have scour holes. Although these local scour holes will not affect the stability of the dam,

the opportunities of overflowing the top of the dam is increased while pushing by the winds

and waves in the reservoir. Theses small scour holes will be rapidly expanded under the

erosion effect of the flood padding through the dam. When the scour holes are reaches a

certain size, the dam will be local instable, and then the dam break phenomenon can be

presented. The engineering grade of the reservoir is grade III, the permanent main

buildings are designed according to the grade 3, the permanent secondary buildings are

designed according to the grade 4, and the temporary buildings are designed according to

the grade 5. The concrete gravity dam is designed according to the flood per 50 years and

is reviewed according the floor per 500 years, the energy dissipation and erosion

prevention buildings are designed according to the flood per 30 years, and these buildings

are in line with the requirements of ―Standard for Flood Control‖ (GB50201-94), so that the

dam break risk caused by the extraordinary flood can be reduced effectively.

(8) Error of survey design

If the early work do not be completed well, the hydrographic survey and the geological

survey are not detailed, the calculation of the water account is incorrect and the design

consider is not thoughtful, the construction may be blind, the hidden danger for the safety

of the reservoir will be caused, and the collapse accident of the reservoir is easy to be

occurred. Thus, for the flood prevention safety of the dam, the correct survey design and

reasonable dispatch application should be paid attention in addition to the reasonable

selection of flood prevention standard. The project has done a lot of preliminary works, so

that a scientific basis is provided to ensure the quality of design.

(9) Quality defects of the dam

During the construction process of the dam, the chance of quality defect is always existed

due to the uncritical local quality control. The weak link is the place for the occurrence of

concentrated seepage and piping, and the dam break can be occurred under the effect of

adverse external dynamic loads. Thus, project supervision in the project should be

strengthened, the supervision, inspection, evaluation and acceptance of the construction

should be organized, and the left tail works should be completed well.

(10) Mismanagement of operation

In the management work of the dam, the probability of man-made omission and

equipment failure is always existed, so that the real-time monitoring for the operation

status of the dam will be influenced, the working status of the dam cannot be reflected in

time, so that the dam will be dangerous and broken. Therefore, the technical management

work of the reservoir should be strengthened, and the safety of the dam should be

ensured.

In summary, the main reason of dam break comprises low flood control standard of the

reservoir, poor construction quality, poor management work and other human factors. But

the safety of the reservoir dam can be ensured and the purpose of promoting benefit and

abolishing harm can be achieved by seriously implementing the Decree [1991] No.77

―Reservoir Dam Safety Management Regulations‖ of the State Council, carefully

implementing survey design while strictly complying with the regulations, strengthening

project quality and technical management work of the reservoir and complying with the

provisions for the safe operation of the reservoir.

4.1.12.2 Risk and Result of Dam Break

Once the dam is broken, the impacts on the upstream and downstream of the dam are

large. In the upstream of the dam, the water of the reservoir area, particularly the water

level before the dam will be sharply reduced due to the suddenly discharge, so that the

bank of the reservoir dam is easy to be unstable, and the bank is easy to be collapsed.

The dam break risk is mainly presented in the downstream, i.e. the dam break wave will

be formed as the suddenly discharge of the water in the reservoir, and the damage to the

human and property downstream the dam is serious. Thus, when the maximum flow of the

dam broken is reached to the flow path L of the downstream dam according to the source

strength of the broken dam, the maximum flow is calculated according to the following

formula:

wherein, QLm represents the maximum flow (m3/s) for the controlled section of the

broken dam apart from the dam with L (m);

Vm represents the largest velocity (m/s) of the river section, the value of that in the

assessment is 3.0 m/s;

K represents the experience factor. The experience factor of the project is 1.2, and the

other parameters are ditto.

According to the topography downstream the project and the resident distribution

condition, the cross-section of rivers of the eight downstream villages which may be

impacted are estimated, wherein the details are shown in Table 4.1-10.

List for Estimation of Cross-section of River of Each Village

6.3 Contract Requirements of Environmental Management

In the project construction, the contractor plays a key role in environmental management,

pollution control and prevention measure and other factors, and therefore the contractors

should be required as follows:

(1) Select the contractor with strength to ensure the effective implementation of

environmental management plan;

(2) The contractors and the construction supervisor must be subjected to the relevant

environmental protection and environmental management training organized by the TA

before starting;

(3) The environmental impact mitigation measures during the construction period above

should be included in the tender documents of the contractor and finally included in the

construction contract as the contract requirements of the contractor of the project.

(4) The environmental activities of the contractor should be monitored, provide a daily or

weekly environmental performance record, and monitor and review these records by the

project office and the construction supervision team.

(5) The contractor should provide a full-time environmental staff for each section. These

environmental staff should be subject to the training of the training plan so as to qualify

their works.

(6) In the construction process, the contractor should communicate and coordinate with the

masses of the project area, establish bulletin board in each construction unit to inform

the public of specific construction activities and construction time, and simultaneously

provide the contact and contact phone to provide complaints and advices of the masses

to the construction activities.

(7) In the project contract funds, the contractors should obligate the deposit of

environmental management and other factors according to the annual budget, wherein

the amount of the proportion should be about 3% of the budget account.

6.4 Information Exchange and Resolution of Undesirable Condition

In the environmental monitoring work, the information should be exposed to the onsite

environmental supervisors, the environmental management managers of the enterprise

and the project office, wherein the information is monthly exposed for one time, the

monitoring report is developed by an environmental monitoring staff and is distributed to

the onsite environmental supervisors, the environmental management managers of the

enterprise and the direction of the project office. In order to focus on the most important

issue of management, the importance of non-compliance basis of the project is divided

into three different levels as following:

Level 1

Definition: the condition of the non-compliance is defined as the project is incongruent to

the original requirement, but the non-compliance will not cause immediate impact on the

particularly important resource. If the recurring of the first level did not be paid attention,

the second level will be caused. Measures: properly handle the situation of the first level

by means of appropriate cooperation and regular exchange. For example, discussing with

the staff of the construction unit and the operation unit, quickly implement remedial

measures, wherein the typically formal communication from is a weekly case report from

the environment supervision engineer to the environmental management manager of the

enterprise and the onsite construction manager.

Level 2

Definition: the non-compliance condition does not cause obvious damage and irreversible

impacts on the sensitive and important resource, but the non-compliance condition should

be remedied and treated immediately to prevent the impacts above. If the recurring of the

second level did not be paid attention, the third level will be caused. Measures: in case of

the discovery of the event of the second level, the event must be reported to the

environmental manager of the project office and the onsite construction manager by the

environmental management manager of the enterprise, so as to achieve remedial

measures as soon as possible, and the remedial measures will be provided in a week

after the discovery, generally.

Level 3

Definition: the level includes the damage to the sensitive objectives paid special attention

or foreseeable and coming damage. The particular behavior internationally prohibited is

also divided into three levels. Measures: report the conditions to the environmental

manager of the project office and the onsite construction manager by the environmental

management manager of the enterprise once discovering, achieve remedial measures as

soon as possible, and the remedial measures will be provided in three days after the

discovery, generally. The time will be longer in case of special conditions. If necessary, the

environmental management manager of the enterprise can require the construction

manager to stop some special projects for protecting the resources before implementing

the remedial measures.

7. Environmental Monitoring Plan

7.1 Monitoring Purposes

According to the characteristics for the impacts of Moba gorge water source engineering

on the environment, the main environmental factors of the project construction area and

the reservoir area before and after the project construction are monitored, the change

conditions of the various environmental factors in the impact range of the project and the

effects after implementing the environmental protection measures are grasped, so that the

basis for finding environmental issues in time, providing the corresponding measures,

reducing the adverse effects of the project, strengthening environmental management and

project completion and acceptance..

In different stages, the focuses of environmental monitoring tasks are different. In the

earlier stage of project construction and water storage, the main monitoring objectives

mainly comprise the change conditions of the environmental factors caused by the

construction activities, the change of the environmental factors caused by dam

construction and water pipeline pavement; when the project is completed and put into

water storage operation, the monitoring objectives mainly comprise the change conditions

of the environmental factors around the reservoir caused by water storage, scheduling

and operation period, and the ecological change in the water pipeline pavement area.

7.2 Environmental Monitoring Organization

The environmental monitoring work in the construction period and operation period is

responsible by the Hydrographic Office of Cheng County, the environmental monitoring

station and the water conservation monitoring center according to the commission of the

project contractor or the operator, wherein all the responsible units are national

environmental quality monitoring units and are featured with complete equipment, thick

technical force, so that these units can carry out the environmental monitoring tasks well.

According to the environmental impact prediction results, the sensitive concerns with

obvious pollution are used as monitoring points so as to track and monitor the pollution

condition of construction period and operation period of the project, wherein the

monitoring content comprises the noise with large impact on the environment, air

environment and surface water environment. The monitoring factors are determined

according to the characteristic factors of project pollution. The monitoring analysis

methods are the monitoring analysis methods for the corresponding items in the

―Environmental Monitoring Technical Specifications" and the ―Water and Soil Conservation

Monitoring Technical Regulations" which are issued by the national environmental

protection administration.

Appendix 2 Detailed Project Environmental Management Standards of Contractor

In construction period, environmental protection is the responsibility of the contractor. The

article 19.1 of the soil mold engineering evaluation Contract of the International

Federation of Consulting Engineers (FIDIC) states that ―in the whole process of

construction, completion and repair other defects, the contractor should take all

reasonable steps to protect the site and its vicinity environment, so as to avoid the

pollution, noise or other results caused by construction and prevent the injury or prejudice

on human and property and other aspects.‖

1. Control measures of air environmental pollution

① Implement civilized construction during the construction period, develop the measures

for preventing dust pollution according to the construction plan, for example, adding

baffles, watering and timely removing earthwork, wherein the transport vehicles should be

covered with a canvas before leaving from the site to the road, meanwhile the material

should be prevented from loading/unloading in wind as much as possible.

② For powdery materials, they are piled up intensively and provided with covering and

sheltering measures to reduce the production of dust.

③ Regularly inspection the working site, subject the sensitive point to TSP monitoring,

and reform the overweight phenomenon in a given time.

④ For the construction which is in violation to the provisions or the problem did not be

reformed in time, administrative and financial penalties should be taken.

2. Control measures of water environmental pollution

① Production and living wastewater is strictly prohibited from discharging without treating,

the construction site should be provided with a wastewater collecting and depositing tank,

and the wastewater is used for watering to reduce the dust or used for concrete mixing

and the like after treating simply.

② The management of the construction site should be strengthened to prevent earthwork

and construction materials and the like from entering into the water close to the piling

place.

3. Control measures of noise environmental pollution

① Replace behind high-noise construction process with advanced low-noise construction

process.

② The speed of the bulldozers, excavators, loading and unloading vehicles should be

limited will accessing the site, and the maintenance of the mechanical equipment and

transport vehicles should be strengthened.

③ Reasonably arrange the schedule and construction time, and avoid the continuing

impact of strong-noise operating machinery on the surrounding residents.

④ Operate the equipment according to the provision, and minimize the impact noise.

⑤ When the construction site through schools, residential and other sensitive points, the

temporary noise barriers (walls) should be set, if necessary.

⑥ Regularly monitor the noise level of the sensitive point, and provide control measures

to the excessive points.

4. Control measures of ecological environmental pollution

① For the land and forest and the like must be occupied in the construction process, the

land acquisition must be completed before starting the project and must be in line with

relevant domestic regulations and the security policy OP4.12 of the World Bank and the

requirements of 4.20.

② For the temporary land occupation of construction, the mellow soil of cultivating in the

original land surface should be stacked aside and leveled when the construction is

completed, so as to restore the land surface.

③ Strengthen the education of the construction worker, promote civil construction, and

protect the wildlife in the construction area.
