1.2 Project Background

Yangqiao Ship Lock is one of the important hydraulic structures of Quan River

Pivotal Engineering, and an important water transportation channel of Linquan

County; the ship lock was put into service in October, 1988 as a Level VI ship lock

for 100-ton ships, and the ship lock size is 100×7.5×2.0 m, with the designed traffic

capacity of 1 million tons. In 1998 – 2005, Fuyang City conducted Fenquan River

Treatment Engineering, and the channel status was greatly improved; however, due to

the limitation of the Yangqiao Ship Lock, ships above 100 tons still cannot go through

the river, they can only arrive to the Yangqiao Ship Lock, so the transfer by vehicles is

required, greatly increasing the shipping cost of goods; meanwhile, the ship lock

cannot meet the enlargement trend of ships, and the water transport function of Quan

River cannot be effectively exerted. In addition, because the intermediate vehicle

transport leads to an increase of the vehicle flow, resulting in heavy damage to roads

and other environmental problems including dust, noise pollution and so on, which

impose serious adverse impact on the living conditions of local people.

Therefore, the Extension Engineering of Yangqiao Ship Lock became

imperative; in November 2006, Liquan County Government submitted Application

Letter for Extension Engineering of Yangqiao Ship Lock in Linquan County to the

3


municipal government, development and reform commission (DARC), transportation

bureau, water bureau and maritime bureau, and the municipal government reported

the application to the provincial DARC. In 2007, after consultation to the provincial

water conservancy and transportation (maritime) authorities, Anhui Provincial DARC

replied to the municipal government, supporting the extension of the Yangqiao Ship

Lock, and required that the preliminary works of the project should be conducted

according to the basic construction procedure, so as to connect with the construction

scheme and finance the construction. Then, the municipal government and the

municipal DARC required the Linquan County Government to organize a legal

person for the project and boosting the preliminary works. On May 16, 2007, after the

study of the county government, the Construction Preparation Group for Yangqiao

Ship Lock Engineering in QuanRiver, LinquanCounty. On January 22, 2009, the

Anhui Provincial DARC approved the Extension Engineering. According to the

approval, in March 2009, Fuyang Municipal Port & Shipping Administration Bureau,

Anhui Province entrusted Anhui Provincial Communications Survey & Design

Institute Co., Ltd. for preparing Feasibility Study Report (FSR) for Extension

Engineering of Yangqiao Ship Lock of Fenquan River whose draft for review was

completed in May, 2009; since the legal person for the project was not determined, the

review meeting was not held for a long time. In April 2012, the legal person for the

project was determined to be Anhui Provincial Port & Shipping Construction

Investment Group Co., Ltd., the engineering name was changed to “Yangqiao Ship

Lock Engineering of Fenquan River, Shaying River Channel”, and the construction

scale of the engineering was adjusted according to the development of shipping

industry and the current status of ships. In May, 2012, with the entrustment of Anhui

Provincial Port & Shipping Construction Investment Group Co., Ltd., Anhui

Provincial Communications Survey & Design Institute Co., Ltd. prepared Feasibility

Study Report (FSR) forYangqiao Ship Lock Engineering of Fenquan River, Shaying

River Channel, and the official reply for the FSR was obtained from Anhui Provincial

DARC on April 28, 2013. The Initial design of Yangqiao Lock Project of Fenquan

4


River, Shaying River channel was completed in April and May 2013, and was

approved by Anhui Development and Reform Commission in July 2013. In Aug.

2013, the Design of construction drawings for Yangqiao lock of Fenquan River,

Shaying River channel was reviewed by experts of the Transport Department of Anhui

Province and approved by the Transport Department of Anhui Province.

The Channel Improvement Engineering of Shaying River having the loan from

the World Bank was reorganized in 2013, and two additional project activities were

proposed, i.e. (1) Yingshang Multi-track Ship Lock Engineering and (2) Extension

Engineering of Yangqiao Ship Lock. In the two engineering activities, a

supplementary report was prepared for the Yingshang Multi-track Ship Lock

Engineering, and an environmental impact statement and an environmental

management plan were separately prepared for the Extension Engineering of

Yangqiao Ship Lock.

1.3 Environmental Protection Work for This Project

According to the environmental administration procedure of a construction

project, as well as the national laws and regulations about environmental protection,

1.6 Work Grade & Scope of Assessment

1.6.1 Work Grade of Assessment

1. Atmospheric environment

During the operation period of the engineering, the atmospheric pollutants are

mainly an extremely small amount of oil exhaust gas from ships passing the lock. The

impact of the engineering to the atmosphere is mainly concentrated in the construction

period; the impact to local ambient air quality is mainly caused by the tail gas from

machines and vehicles during the construction period, and the main pollution factors

include TSP, etc. The construction area of the engineering is mainly on the flood land

of Quan River, so the atmospheric diffusion conditions are good; also, the convenient

traffic brings relatively good fundamental conditions like traffic in construction.

During the normal construction of the project, the impact to the atmospheric

environmental quality is relatively small, and the impact to the external environment

will end with the end of the construction period. According to the content about the

grading of the assessment work in Technical Guideline for Environmental Impact

10


Assessment – Atmosphere Environment (HJ 2.2-2008) and the environmental

characteristics of the engineering location, the assessment conducts mainly the brief

analysis to the impact to the ambient air in the construction period.

2. Water environment

The impact of the project to the water environment is mainly the impact to the

water quality of Quan River from the waste water in the construction period, oily

water from ships passing the lock during the operation period, as well as domestic

sewage. In the pollutants, the waste water in the construction period is mainly from

the production sewage in the construction period and the domestic sewage from the

construction staff, and the amount is relatively small; the pollutants in the operation

period are mainly small amounts of domestic sewage and oily water from the cargo

ships, which can be treated or collected with the equipment on the ships. Therefore,

according to the relevant provisions in Technical Guideline for Environmental Impact

Assessment – Surface Water Environment, the determined grade of the water

environment assessment is III. The assessment is mainly for the current status of the

water environment, and analyzes the impact to the water environment due to the

implementation of the engineering.

3. Acoustic environment

Before and after the construction of the project, the sound increment of sensitive

targets is below 3 Db (A), and the population influenced is not changed greatly,

according to the relevant provisions in Technical Guideline for Environmental Impact

Assessment – Acoustic Environment (HJ 2.4-2009), the determined grade of the

acoustic environment assessment is III.

4. Ecological environment

The area influenced by the engineering of the project is mainly the flood land of

Quan River, and is within the administration scope of Yangqiao Ship Lock, Yangqiao

Check Gate and the river channel; the total land occupation of the engineering is

11


16.91 hm2, less than 20km2; no rare or endangered species exist in the area, and the

area does not relate to an ecological sensitive area. The impact of the engineering to

the ecological environment is mainly the water & soil loss caused by the disturbance

of the engineering construction area to the land surface. Therefore, according to the

relevant provisions in Technical Guideline for Environmental Impact Assessment –

Ecological Impact (HJ 19-2011), the determined grade of the ecological environment

assessment is III.

5. Solid waste

The solid waste of the project is mainly from the discarded soil from excavating

the lock chamber. During the operation period, the solid waste is mainly a small

amount of domestic waste from the crew of the ships passing the lock, and the waste

can be collected in the containers of the ships. The assessment will make a comment

to the reasonable disposal of the solid waste.

1.8 Environmental Protection Objectives

According to the characteristics of the construction project, the main targets of

environmental protection in the area for assessment are the villages within the 200 m

range around the proposed ship lock site. According to the on-site investigations, no

important cultural relic or key target of environmental protection like ancient and/or

famous trees (or other valuable animals or plants) requiring protection. The vegetation

on the lands occupied by the project permanently or temporarily includes only locally

common natural vegetation and artificially cultivated plants, no basic farmland,

woodland or rare/endangered species requiring special protection.

The main target of environmental protection in the project is to prevent the

functions of the surface water environment, the air environment and the acoustic

environment from any adverse change, and the targets of the ecological environmental

protection include mainly the landscape ecology in the area, as well as the agricultural

ecological system and water ecological system around.

According to the on-site scouting & investigation, and in combination with the

construction characteristics of the engineering, the current status and the functions of

the construction area & influence area of the engineering, the main targets of

environmental protection determined in the environmental impact assessment are

2.1 Current Shipping Status of Fenquan River

2.1.1 River Overview

As one of the main tributaries of Ying River, Fenquan River has its source in

Shaoling Hillock of Yancheng County, Henan Province; Ni River flows into the

Fenquan River in Hongshangmiao Village, Shenqiu County, the part of the Fenquan

22


River before the Ni River Mouth is called as Fen River, and the part after is called as

Quan River, which is the origin of the name “Fenquan River”. The river flow through

Yancheng County, Shangshui County, Xiangcheng County and Shenqiu County of

Henan Province, and Fuyang City of Anhui Province; the overall length of the river

channel is 241 km, 82.27 km in Anhui (Zhoulou – Fuyang), and the drainage area is

1990 km2. In Fuyang, Fenquan River flows through Linquan County, Jieshou City,

Yingquan District and Yingzhou District, and into Ying River in Sanli Bend, Fuyang

City; its tributaries include Liuan River, Xian River, etc. The existing Yangqiao Ship

Lock on the Fenquan River is in Yangqiao Town, Linquan County.

2.1.2 Current Status of Channel & Port

The Anhui channel segment of Fenquan River starts from Linquan County to the

mouth of Quan River, Fuyang City with length of 80.4km, and the channel is divided

into two sections by the Yangqiao lock. The upper section starts from Zhoulou to the

upper Yangqiao lock with the width of 70~105m and water depth of over 2.0m.

Because the channel bends here and there with many acute angles and the minimum

bending radius of about 100m, 300-ton ships can sail on the channel in most of time;

the lower section starts from Yangqiao lock to Sanliwan with the length of 54.27km,

where the river section from the lower Yangqiao lock to Sanshili is 36.62km, and it is

currently ranked Grade VI channel, which is similar to the upper section from

Zhoulou to the upper Yangqiao lock; the section from Sanshili River to Sanliwan is

17.65 km long with the width of about 100m, it is currently ranked Grade VI channel,

the channel is straight with less curve and the water depth is over 3.5m, so 500-ton

ships can sail on the channel.

23


Figure 2-1 Staged schematic of the Quan River channel

Affected by the Yellow River floods, the beach height on both side of Quan

River is increased and many bending sections exist, so floods and waterlog frequently

occur. Quan River has been reconstructed and improved for many times in the history.

In 1950s, for the blocked section from Kanheliu to the mouth of Quan River of

Sanliwan, bends were removed and straight sections were kept, which makes the

channel from Sanshili River to Sanliwan straight with less bends. In 1994, mechanical

dredging was performed on Xiaowan, Qiandawan, Yingzhuang and other shoals

below Yangqiao lock by Fuyang Water Department. In 1998-2005, Fuyang

implemented the initial improvement project of Anhui Fenquan River (this project is

one of 19 key Huai River improvement projects determined by the State Council’s

Decision on further improvement of Huai River and Lake Tai), and the channel from

the mouth of Huai River and Lake Tai to the mouth of Quan River was dredged

pursuant to 90% of the once-every-three-years standard; bending sections were cut off

and straight sections were kept in some bending sections of Wangdawan, Jing Wan,

Liu Wan, Dahuwan, Qiandawan, Qianyanwan and Laowanzhai (see Fig. 2-1), which

largely improved the channel conditions so that the flood prevention standard of both

banks of Quan River reaches once-every-20-years standard; after dredging, the width

of Quan River is 25~30m, the lowest navigation water level is 2m (300t ships can be

navigated), the normal water level is 3.5~4m (500t~1000t ships can be navigated). In

the end of 2007, the project was successfully accepted after completion. It not only

increases the flood and waterlog prevention standard of the main stream of Fenquan

River, but also improves irrigation and shipping conditions, expands drainage outlet

for branches of both beaches and river surface, and makes full advantage of the main

stream and branches on the Fen River’s upstream which have been improved.

Figure 2-2 Schematic of bend-cutting-off and straight-section-keeping of Quan River

There are 8 crossing bridges along the channel of Quan River. The current

situation of those bridges along the channel is shown in Table 2-2. Most of navigation

hole spans for bridges is 30m, the net height is normally less than 5m, but most of net

height is around 4m. Based on the data analysis, the number of impended navigation

days is limited. It can be seen from Table 2-2 that the number of impended navigation

days for the bridge changed from ferry is the longest, about 60 days, and the average

number of impended navigation days is less than 15 days. Considering that some

bridges with insufficient clearance have less number of impended navigation days, the

bridges over the channel can fundamentally meet the navigation requirements.

Two operation areas, Chengguan and Yangqiao, are set in the Linquan port area.

Chengguan operation area, completely built in 1986, boasts a total of eight berths with

the length of 260m and the annual shipping capacity of 300,000 tons, and 100-ton

ships can be berthed here. Yangqiao operation area, completely built in 1991, boasts a

total of four berths with the length of 200m and the annual shipping capacity of

400,000 tons, including three berths for bulk cargo and one berth for dangerous

goods, and 300-ton ships can be berthed here.

Through analysis on the current situation of channels, crossing bridges and port

areas, the water depth of channels and clearance of crossing bridges of Quan River

27


can basically meet the requirements of Grade IV lock navigation. For the purpose of

maximizing the economic efficiency of Yangqiao lock, it is recommended to perform

construction of the Quan River channel improvement project and Chengguan and

Yangqiao operation areas in Linquan port area.

2.1.3 Hubs and Other Water Conservancy Facilities

Yangqiao Hub lies in Yangqiao Town of Linquan County, and is an important

water conservancy control hub building of Fenquan River. It has the functions of

preventing surface water loss, fully utilizing reservoir capacity of riverbed, raising

underground water level by appropriately increasing water storage, and developing

farm irrigation & shipping. The hub is composed of the Old Gate, the New Gate and

the Ship Lock. The construction of Old Yangqiao Ship Lock began in 1958 and was

completed in May 1961; the gate has 7 openings with the size (width × height) 5 × 5.5

m, gate floor elevation 27.8 m, gate top elevation 33.30 m, and adjacent dyke top

elevation 35.8 m, and the energy dissipation is done in a stilling basin. The Old gate

adopts reinforced concrete plain batten gate, and has 7 winch hoists with the hoisting

capacity of 15 t. The designed flow rate for draining water logging is 1,090 m3/s, and

the designed flow rate for draining flood is 1,630 m3/s.

The construction of the New Gate began in 1975 and was completed in May

1976; the gate has 14 openings, 7 deep ones and 7 shallow ones in two layers with

different heights. The deep openings have the size of 5 × 4 m, and for the shallow

ones, the size is 5 × 3.5 m; the gate floor elevation is 25.0 m, the gate top elevation of

deep openings is 29.0 m, and for the shallow ones, the elevation is 33.0 m. The

adjacent dyke top elevation is 35.8 m, and the energy dissipation is done by baffle

sills; the gates used are shell gates in the upper part and concrete plain batten gates in

the lower part; 7 winches (2 × 25 t) are used for the deep openings, and 7 (2 × 15 t)

are used for the shallow ones; the irrigation area is 156 thousand mu. The Yangqiao

Ship Lock has the designed levels of 32.8 m in upstream of the gate and 32.6 m in

downstream, and the designed flow rate of 1,090 m3/s; the calibrated values are: 34.66

28


m in upstream of the gate, 34.35 m in downstream, and the designed flow rate of

1,630 m3/s. For the highest actual level on August 17, 1975, the values are: 34.75 m in

upstream of the gate, 34.53 m in downstream, and the flow rate of 1,440 m3/s.

The Old Yangqiao Ship Lock is located in the left bank (the northern side) of old

Yangqiao lock of Fenquan River, with the grade of VI, and the standard for 100-ton

ships; the size of the ship lock is 100 × 7.5 × 2.0m, and the designed traffic capacity is

1 million ton.

The dyke grade of the river segment in which the engineering exists is 3, and the

current dyke is the one reinforced in the Initial Treatment Engineering of Fenquan

River from 1998 to 2005; the dyke top elevation is 37.01 – 38.0 m, the top width is

about 8 m, and the ground in the dyke is slightly high (elevation about 34 m); the ratio

of the side slope facing the river is 1:3.

2.2 Necessity of Engineering Construction

The Yangqiao Ship Lock is one of the important hydraulic structures of Quan

River Pivotal Engineering, directly influencing the water bulk cargo transportation of

Linquan County; the water transportation route begins at Quan River, then goes to

Shaying River, Huai River, Beijing-Hangzhou Canal, and finally Changjiang River.

The area has fertile land and abundant natural resources, and is one of the commodity

grain bases & important energy industry base in China. The direct hinterland of the

area includes mainly Linquan County, Fuyang City and Yingshang County, and the

indirect hinterland can be expanded to Henan, area along Huai River, Jiangsu,

Zhejiang, Shanghai, etc. The direct hinterland includes the coal industry city in China,

an important transportation hub city in East China, a trade center, and a regional

central city for comprehensive processing industry; they have different characteristics

and broad development prospect.

With the national economy development & resource development in the

29


hinterland, particularly the continuous improvement of the productivity of Linquan

Chemical Industry Co., Ltd., and the continuous development of agricultural &

sideline product processing industry in Linquan County, the lockage amount of the

Yangqiao Ship Lock will increase continuously, and it is expected to be 4.8 million

tons in 2020, and 6.1 million tons in 2030. The necessity of its extension is mainly

shown in the following aspects:

1. Traffic pressure

The social & economy development of the hinterland requires a pattern suitable for

great traffic. With the unique advantages like large transport volume, small

investment, low cost and sustainable development, the water transport shoulders the

transport of bulk cargos and long-distance transport, particularly the transports of

goods like chemical products, grains, agricultural & sideline products to Jiangsu,

Zhejiang and Shanghai. Currently, Linquan County has no railway, and the water

transport plays an important role in the traffic strategy of hinterland, and it is

necessary to fully utilize the important function of water transport on Quan River in

the comprehensive transportation of the County. In 1998 – 2005, Fuyang City

conducted Fenquan River Treatment Engineering, and the channel status was greatly

improved; however, due to the limitation of the Yangqiao Ship Lock, the navigation

capacity of Quan River is not improved all the time, which becomes a bottleneck

hindering the economy development of Linquan County. The extension of the

Yangqiao Ship Lock can improve the shipping conditions of the whole channel of

Quan River, speed up the flow of materials and facilitate the fast development of

regional economy in the basin; meanwhile, the traffic pressure in Linquan County can

be remitted, and the extension is beneficial to the formation of a comprehensive

transport network pattern integrating multiple transportation types like highway, water

transport, railway, etc. in the hinterland.

2. Environmental benefits

The land resource is limited and non-renewable. With the fast development of

30


economy, land for various types of construction is increased greatly and the farmland

is reducing gradually; currently, China controls the land for construction strictly, and

enhanced the administration and approval of land resource. By paying effort to the

development of inland water transportation, the land resource can be effectively

protected. In addition, the water transportation has the advantages including large

transport volume, low energy consumption and less pollution, so it is an environment-

friendly and resource-saving transportation means. After the extension of Yangqiao

Ship Lock, the channel of Quan River will fully exert its transportation function, the

land occupation caused by construction of railway or highway is prevented to some

extent, which is beneficial to land resource protection, resource conversation and

pollution reduction. In addition, compared with highway traffic and railway traffic in

general, the water transportation has smaller noise and less influence to the sensitive

points along the channel. The extension will improve the environmental situation in

neighboring areas as well as living quality of residents nearby.

According to the statistics of information in near 20 years from 1986 – 2011, for

many years, the highest monthly average level of Yangqiao Ship Lock upstream is

30.43 m in September, and the lowest one is 29.35 m in June and November; for the

Yangqiao Ship Lock downstream, the highest monthly average level is 28.07 m in

July, and the lowest one is 27.22 m in February. The monthly average levels of

Yangqiao Ship Lock upstream and downstream are shown in Table 2-4 and Table 2-5

respectively.

2.3.3 Relationship Between Yangqiao Ship Lock & Yangqiao Check Gate

The construction of Yangqiao Check Gate began in 1958 and ended in May

1961; in 2004, the gate was reinforced. The check gate has 7 openings with the size of

5 × 5.5 m, the gate floor elevation is 28.1 m, and the gate top elevation is 33.20 m.

The Yangqiao Check Gate is mainly used for adjusting the upstream & downstream

levels of the gate, and meeting the needs of passing ships and water usage of upstream

& downstream. Yangqiao Ship Lock is located in the left bank of the Yangqiao Check

Gate and is mainly used for allowing the ships to pass; the Yangqiao Ship Lock is one

32


part of the Yangqiao Hub, and its calibrated flood level is the flood level of Yangqiao

Check Gate on once-in-two-decades basis; the ship lock is not used for flood

discharge, and does not occupy the flood discharge section of the channel or the Hub,

so it does not affect the flood discharge of the Yangqiao Hub.

According to the Document of the People’s Government of Fuyang City [1996]

No. 191: Official Reply for approving Control & Utilization Plan of Large Water Gate

in 1996, the regulation scheme of the Yangqiao Check Gate is: 29.5 - 30.5 m in a

flood season, and 30.5 - 31.5m in a non-flood season.

2.3.4 Navigation Standard & Construction Scale

As the largest tributary of Huai River, Shaying River is one important part of the

channel network of Henan Province, Anhui Province and Huai River Basin, and one

tributary of “two main streams & three tributaries” backbone channel network of

Anhui Province, with the planned grade of IV. Quan River is the largest tributary of

Shaying River, having a long navigation history. The Yangqiao Ship Lock of Quan

River plays an important part in the hinterland water transportation network;

according to the prediction results of economy and transport volume in the hinterland,

as well as the current status and the plan of the channel, the construction scale of the

Yangqiao Ship Lock is Grade IV, and the lock is designed for 500-ton ships and also

applied to 1,000-ton ships, i.e. lock chamber size: 200 × 13 × 3.5 m (length × width ×

water depth on sill). The designed annual traffic capacity is 6.72 million tons.

2.3.5 Water Resource Conditions of Quan River

The water source of Quan River mainly originates from precipitation and other

branches and the difference between the upper and lower water levels of Yangqiao is

around 1m in the dry period. The water resources of Quan River are rich, so the upper

and lower water depths of the lock can be kept at over 2m in the mid-dry season.

As the upper water level of Yangqiao lock is mainly controlled by the Yangqiao

33


check gate, the lower water level of Yangqiao lock is mainly controlled by the Fuyang

lock. After the reconstruction and expansion of locks, the upper and lower water

levels of locks are still controlled by Yangqiao check gate and Fuyang lock, so the

water level of upstream and downstream approach channels has no change

fundamentally.

Based on the feasibility report, after completion of locks, the two-way lock-

crossing time is 45 minutes, the total irrigation volume is 5227m³, the irrigation or

discharge time of the lock chamber is about 10 minutes, and the average water

consumption per day of the lock is 1.93m³/s. The lock draining is a short process and

the water in the approach channel remains at rest in most of time. Even in the draining

process, the water flow speed in the approach channel (the bottom width is 35m and

the minimum water depth is 2 m) is rather small. After the lock is completed, the

downstream main channels still keep the same as before. The irrigation time of the

lock chamber is about 10 minutes, the flow is about 8.7m/s and the flow rate is only

0.3m/s, which can be seen that the lock irrigation imposes less impact on the flow rate

of the upstream approach channel.

According to the project feasibility calculation, the average water consumption is

2.1m3 when 1-ton cargoes cross the lock. With the increase of freight transport across

the lock, the number of lock draining increases as well, which will consume a certain

amount of lock storage capacity. As the water level is mainly controlled by the check

gate, the water resources shall be optimally used by cooperating with relevant water

departments in the operation in line with the requirements of water utilization for

shipping.

2.4 Ship Lock Engineering

2.4.1 Lock construction scale

After expansion is completed, Yangqiao lock is Grade IV, the maximum ship

34


tonnage is 500 tons, the effective dimension of the lock chamber is 200×13.0×3.5m

(length×width×threshold water depth) and the lock is single-line and single-stage ship

lock. The line segment of the upstream approach channel is 344.2m, the line segment

of the downstream approach channel is 488.4m and the bottom width of the upstream

and downstream approach channels is 40m; one management zone shall be

constructed. The lock-crossing time is 45min and the number of navigation days is

330 days.

过1. Prediction of lock-crossing transport capacity

According to the statistical data of the lock-crossing transport capacity of

Yangqiao lock from 1991 to 2010, the lock-crossing transport capacity reached 72,000

tons in the early nineties, then it gradually decreased, and it was only 10,400 tons in

2005; after that, it gradually increased. Generally speaking, it experienced from large

to small and vice versa, so it can be kept within 10,000 tons annually. The main cargo

types are chemical raw materials and products, chemical fertilizer, grains, coal and

other bulk goods. In addition, mining and construction materials account for a certain

proportion to them. Coal and mining and construction materials are mainly purchased

from other places, and other cargoes are sold to other places, mainly to Jiangsu,

Zhejiang and Shanghai. In 2009 and 2010, the cargo transport volumes in Yangqiao

operation area were 140,900 and 187,000 tons respectively with a significant increase,

which shows a trend of a gradual increase in water transport in recent years.

According to the prediction, after the modification engineering of Yangqiao Ship

Lock is completed, the total goods transport volume will be 4.8 million tons in 2020,

35


including 1.75 million tons for upbound transport, and 3.05 million tons for down

bound transport; in 2030, the total goods transport volume will be 6.1 million tons,

including 2.45 million tons for upbound transport, and 3.65 million tons for down

bound transport. According to the meteorological condition of Linquan County, the

navigation time of the Yangqiao Ship Lock is determined to be 330 days.

2. Calculation of water consumption of ship lock

On the basis of the designed annual goods transport volume (7.3 million tons)

passing the ship lock in single direction, the average water consumption of the ship

lock is 1.93 (m3/s) in one day, the average water consumption for each time passing

the lock is 5,227 m3, and the average water consumption for each ton of goods passing

the lock is 2.1 m3.

3. Water level design

The water levels of Yangqiao lock are designed as follows:

2.4.2 Overall layout of the lock

（1）Overall layout of the lock chamber

As the project is an expansion project, it is recommended to select the original

location as the lock construction location by virtue of principals of less land

acquisition, less demolition and making full use of available sources. Namely, it is

recommended that the lock center shall be built at 2.8m to the left of the old lock

center (i.e. in the slight north direction) and about 159m away from the check gate

center, so that the lock layout is basically smooth and straight compared to the built

dikes. The head bay is the floodgate head, which is laid at 93m of the upstream of the

head bay of the old lock; while the tail bay is located at the original tail bay of the old

lock and laid along water retaining buildings, and the lock chamber is located between

lock heads. The head bay is 21.5m long, the lock chamber is 200m long and the tail

bay is 23m long.

（2）Overall layout of approach channels and berth areas

The layout plan of the lock approach channel for this expansion project adopts

asymmetric design by dredging the original channel. The temporary berth areas are set

37


on the upstream and downstream, where the temporary upstream berth area is located

on the left beach outside the mouth of the approach channel and the temporary

downstream berth area is located on the left beach of the approach channel opposite to

Yangqiao dock. The recent berth area will be made by excavating a water course so

that ships waiting for crossing the lock can park here temporarily. The temporary

upstream berth area is made by excavating the original river channel and beach land,

the excavated water course is 317.9m long, 40m wide and 24.10m bottom elevation,

and its two ends are connected to the channel through a bell mouth of 135°. The

temporary downstream berth area is made by excavating the beach land, the

excavated water course is 200m long, 40m wide and 22.09m bottom elevation, and its

two ends are connected to the channel smoothly.

2.8 Organization & Technology for Construction

2.8.1 Organization for Construction

1. Traffic in and out of the site

During the construction period, in order to reduce interference and facilitate

management, the main temporary facilities for construction are arranged on the right

side of the ship lock, and in-site roads to the living area, the construction site and the

aggregate storage respectively should be built.

2. Water supply, power supply & communication systems

Water supply system: the water for production and living adopts underground

water source, and the water for production can use the underground water from deep

wells with water level dropped; an elevated tank with the volume of 100m3 will be set

48


up, and pipelines will be laid to all water usage points.

Power supply system: the peak power capacity for the construction of the

engineering is about 200 kW; currently, a 10 kV power supply line exists on the check

gate, with the transformer capacity of 50 kVA, and the permanent capacity increase of

100kVA from the ship lock; the power line can be set up and used in advance, and add

a 100 kVA transformer temporarily. In addition, a 75 kW diesel power generator is

arranged for backup.

Communication system: in combination with the ship lock management

facilities, 2 computerized telephones are arranged.

3. Factory area & facilities for construction

The concrete mixing system is arranged outside the excavation line on the right

side of the lock chamber, the aggregate storage, the cement storage and the concrete

precast yard are arranged near each other. Two mortar mixers are respectively

arranged on the upstream & downstream wing walls. The power distribution room,

the steel bar & wood processing plants, the on-site storage, the facility storage and the

gate processing plant are arranged on the ground along the downstream bank slope of

the check gate.

4. Construction Camps

The houses for the livelihood welfare of the employees are arranged between the

5-opening check gate and the ship lock, and office buildings can be located within

lock management area.

2.8.2 Construction technology

1. Pit drainage

According to the terrain & geological conditions, homogeneous soil cofferdams

are built by filling in the ends of the upstream & downstream approach channels, and

the corresponding designed flood return period is 5 – 10 years; considering the

circumstances like construction in all year round and passing a flood season, the flood

standard of once-in-decade is selected, the corresponding levels are 34.31 m in

49


upstream of the ship lock and 33.51 m in downstream. During the water retaining

period of the cofferdams, the incoming water from upstream is adjusted by and

discharged through the Yangqiao Check Gate. The section size of the cofferdams

should meet the requirement of stabilization; for the cofferdam in the downstream,

temporary traffic should also be considered, and the top width of the cofferdam in the

downstream is 7 m. The cofferdam in the upstream is arranged 360 m outside the head

bay with the top length of 110 m and the top width of 3 m, and the ratios of its inner

& outer side slopes are both 1:15; the cofferdam in the downstream is arranged 350 m

outside the head bay with the top length of 60 m and the top width of 7 m, and the

ratios of its inner & outer side slopes are both 1:3; homogeneous soil cofferdams are

adopted in the plan.

The stable underground water level in the site of the ship lock is 30.5 m, and the

minimum elevation for foundation pit excavation. In order to keep the earth

excavation for the foundation pit in a dry land environment, and to prevent the

disturbance to the base soil layer, the underground water level must be lowered to at

least 0.5 m below the minimum bottom elevation of the foundation pit, and the water

lever reduction is above 12.2 m. The frequent water discharge is mainly for water

seepage and rain in the foundation pit. Open draining ditches and water-collecting

wells are excavated around the foundation pit, and submerged pumps are used to

discharge the water; the water level of the foundation pit is reduced by excavating

deep wells.

Selection of pumping equipment: compared with the deep-well pump, the

submerged pump is more light and flexible, and has less power consumption, simple

technology and convenient use; therefore, QP-25 electric submerged pump is selected,

it has the lift of 25 m, and the corresponding flow rate of 15 m3/h; 29 such pumps are

selected according to the backup amount of 30%.

Draining ditches should be arranged on both sides of the foundation pit outside

its excavation lines, the pumped water is gathered in the water collecting wells, and

then discharged to the river channels on both sides through the main ditch. Concrete

pipes should be buried in the crossing positions of the draining ditches and the roads

or the like.

50


2. Construction of earthwork

In the beginning of December 2013, the earthwork began officially, the

foundation pit for the ship lock was excavated initially and the work was finished in

one month and a half; in the end of December, the excavation of the upstream &

downstream approach channels began, which generally ended in the end of February

2014; ridges were reserved on the river banks of the upstream & downstream

approach channels, and will be dredged before the completion acceptance of the

engineering.

The earth excavation engineering is conducted in three segments, i.e. the

foundational pit segment, and the upstream & downstream approach channel

segments; the spoil is discarded on the temporarily acquired land. At the same time of

excavation, the fill should be prepared according to the soil quality requirements and

the engineering amount of the fill, and be stacked on the right side of the ship lock.

After the initial water drainage of the foundation pit is completed, the desilting work

of the channels will begin, and the earth excavation for the old ship lock demolition

will be conducted in coordination with the concrete remove and the like. The order of

the excavation is: firstly the earth excavation of the navigation walls, the head & tail

bays and the lock chamber, so as to provide a working plane for the subsequent

foundation treatment and concrete casting, and secondly, the earth excavation of the

upstream & downstream channels; the earth excavated is mainly used for building the

upstream & downstream navigation dykes and filling back for buildings, the earth for

the former is stacked temporarily in near positions, and the earth for the latter can be

transported to the working plane directly, but for some earth from the channel, drying

by solarization shall be considered before stacking onto the dykes.

(1) Excavation of foundation pit

The width of the reserved working plane for the excavation of the foundation pit

is 3 m. In excavation, the earth above 36.0 m elevation within the range 2 m outside

the eexcavation line of the foundation pit should be totally eexcavated, then side

slopes with the ratio of 1:2 are made according to the soil quality and the excavation

depth, and construction platforms with the width of 3 m should be reserved in the

elevations of 25.5 m and 30.5 m.

51


In the eexcavation of the foundation pit, considering that a scoop tram is suitable

for the eexcavation of earth with the depth of 5 m. The earth eexcavation with the

elevation of 25.5 m or more is mainly conducted by scoop trams, with the cooperation

of bulldozers; for the earth with elevation less than 25.5 m, the eexcavation is

conducted by excavators and the earth is conveyed by dump trucks; in order to

prevent excessive mechanical eexcavation, and disturbing the base soil layer, 30 cm

should be reserved in the mechanical eexcavation, and the bottom is cleared

artificially.

The planned period of the eexcavation of the foundation pit was one month and a

half, the eexcavation conducted by the scoop trams took one month and the work by

the excavators took half a month. According to the amount of excavation, 20 trailer-

type scoop trams with the buckle content of 2.5 m3 were selected, the average

productivity of each scoop tram is 200 m3/day; two WY100 backhoe eexcavators were

selected, and each of them worked together with 5 8-ton dump trucks, and the average

productivity of each excavator is 1,000 m3/day.

(2) Eexcavation of approach channels

The eexcavation of approach channels was mainly dredging, and the part above

the elevation of 25.5 m is considered as the eexcavation conducted by the scoop

trams; since the berthing structures adopt gravity structure, the underground water

level should be reduced; for the earth with elevation less than 25.5 m, the eexcavation

is conducted by backhoe excavators, the earth is conveyed by dump trucks, and water

seepage is solved by open drainage. The eexcavation of the segment connected with

the river channel is conducted by hydraulic extraction. The underwater parts of the

entrance & exit of the approach channels will be dredged with small dredgers after the

end of the main body engineering

The total volume of earth eexcavation of the approach channels is 230 thousand

m3. 20 scoop trams with the buckle content of 2.5 m3 were selected for the

eexcavation conducted by the scoop trams, the average productivity of each scoop

tram is 200 m3/day, and the construction period was 30 days; for the eexcavation

conducted by the eexcavators, 5 WY100 backhoe eexcavators were selected and each

of them worked together with 5 8-ton dump trucks; the work is done in two shifts per

52


day, the average productivity of each excavator is 1,000 m3/day, and the construction

period is one month; in the excavation of the sludge section, 2 4PL-250 hydraulic

extraction units were used, the average productivity of each unit is 300 m3/day, and

the construction period is one month. River water can be directly pumped as the water

source of hydraulic extraction, and the sludge is flushed to the mud-dumping area

through steel pipes with the diameter of 100 mm.

3. Construction of reinforced concrete engineering

After the excavation of the foundation pit, the concrete structure construction

began; the casting of the head & tail bays was completed in the end of April 2014, and

the casting of the lock chamber, the upstream & downstream wing walls will be

completed in May 2015. The stonework and the concrete structure are constructed in

parallel, the bottom protection & slope protection in upstream & downstream will be

completed before the end of May, and the casting of concrete berthing columns will

be completed before the end of July. After the concrete engineering of the main body

and the wing walls is completed, the backfill of the foundation pit will begin, which

will be completed in the end of June.

The concrete cast-in-place & mixing system for the ship lock adopts HZS50

Concrete Mixing Station, having the following characteristics: simple equipment,

good adaptation, feeding with a hydraulic bucket, automatic measurement with a

photoelectric control platform scale, hourly output 50m3, fast and convenient pump

transportation.

The mixing station is arranged in the temporary construction site, and adopts

pump transportation through pipelines; the mixed concrete is directly sent to the

casting area without any other auxiliary equipment, and the operation is simple, fast

and convenience.

(1) Concrete casting procedure

In the concrete casting, the ship lock is divided into several casting blocks

according to the structural joints; with the canter composed of the head and tail bays

and the lock chamber, the casting order is arranged in the principles of “deep one first,

heavy one first and main one first”. The casting of the head and tail bays comes first,

53


and the casting of the lock chamber comes second, but the casting of different parts

can be lapped reasonably and done in a slightly alternate way

(2) Methods for concrete construction of different parts

① Construction of floor

In the construction of the floor, 0.15 m×0.15 m square precast concrete columns

are used for building the scaffold for conveying the concrete and operation, and the

scaffold is disassembled when the casting is nearly completed.

The floor should be cast in one time, if not, step casting method should be

adopted; the floor is casted in three steps along the longitudinal direction of the ship

lock, and the width of the step should not be less than 1 m; the slope ratio should not

be less than 1:2, the unloading width in the forward direction of the casting blocks is 3

m, the time interval between different layers should be shortened in order to prevent

cold joint.

bolts are penetrated into the pores and 100 × 100 mm precast hollow concrete support

pillars having the same thickness with the walls, and both ends of each bolt are

protruding from the formworks and are fixed with the top beams. After fixing the

formworks on both sides of the wall with the counter bolts, the formworks are

supported with φ48 × 3.5 split steel pipes so as to prevent the overall deflectionor

deformation of the formworks; the split steel pipes are connected with the top beams

with the aid of diagonal bridging, so as to improve the overall stability of the

formworks.

In the casting of the concrete, chain barrels shall be hung on the scaffold on the

54


top of the mould, the concrete is cast through the chain barrels and the personnel for

casting shall operate in the mould. In order to keep the mutual stability of the walls

and the uniform force deployment on the floor, the concrete for different walls should

be raise uniformly and cast in a layered way, and the thickness of each layer of

concrete should be within 0.5 m.

filling the foundation pit is conveyed with 2.5 m³ scoop trams, levelled with

bulldozers and compacted with caterpillar tractors; the fill in 1-meter range from the

building is tamped with frog hammers and artificial work, so as to achieve the

designed dry density requirements.

Before the earth filling, the base should be cleaned so as to remove ponding,

55


sludge, etc. The earth for filling shall meet the design requirements and its water

content shall be strictly controlled; each layer has the thickness of 0.25 m, after

compacting the layer, the earth shall be sampled according to relevant provisions, and

the earth filling should not continue until the earth samples are tested and meet the

design requirements.

Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 4 Regional Environment Overview

3. Engineering Analysis

3.1 Analysis of Environmental Impact Factors

3.1.1 Environmental Impact Factors of Construction Project & Identification of

Their Impact Degrees

The Extension Engineering Project of Yangqiao Ship Lock has mainly the

following impacts to the environment: domestic sewage discharged by the

construction staff, suspended solid content (SS) increase in the water during the

excavation, residue water from drying and dewatering of the sediment after being

conveyed to the mud-dumping area, oil pollution caused by the construction

machines, land occupation due to stacking sediment, environmental impact to the air

around caused by the odor of the mud-dumping area and the tail gas from

gasoline/diesel engine of construction equipment (like vehicles and ships), mechanical

noise impact of construction machines, possible impact to traffic from sludge & earth

transportation, impact to local economy from engineering construction, and impact to

land utilization & landscape from the recovery of the spoil ground.

3.1.2 Analysis of Environmental Impact Factors of Construction Project

The environmental impact analysis results of the extension engineering of the

ship lock are shown in Table 3-1; the adverse impacts of the engineering appear

mainly in the construction period, such impacts are mostly reversible and local, and

most of the impacts are short-term ones. Positive impacts appear mainly after the

extension of the ship lock, and such impacts are long-term and extensive. Therefore,

after the implementation of the engineering, its positive impacts will dominate.

3.1.3 Analysis of Environmental Factors Restricting Construction Project

Yangqiao Ship Lock is located in Yangqiao Town of Linquan County, the current

status of the air environment in the area is good, and there is no residential area in 50

m range from the mud-dumping area; the heavy metal content in the sediment from

the river bottom is small, so the sediment can be used in farmlands or woodlands;

therefore, the ambient air quality, the sound quality and the solid waste restrict the

project less. According to on-site investigation, the domestic water of the residents in

the village on the west of the ship lock is mainly from the underground water. The

sediment is stacked in the mud-dumping area during the construction period of the

extension engineering of the ship lock, occupying some land, destroying the original

status of the mud-dumping area, and causing more water & soil loss amounts in short

time; also, the construction period may cause certain impacts to the activities (like

travel) of the residents on the west of the ship lock, but the impacts can be minimized

with some protective measures.

3.2 Recognition of Environmental Impacts

3.2.1 Recognition of Main Environmental Problems

During the design period, the adverse environmental impacts should be

minimized, which is mainly reflected in the reasonable ship lock position arrangement

59


and the bridge engineering design, so as to effectively control the adverse

environmental impacts, and to meet the traffic requirements of ships.

The main environmental problems during the construction period include: the

impact of the construction noise to the ambient noise of the construction area and the

area around; the impact of fugitive dust on the road to the ambient air quality; the

impact of the stacking of sediment to the ecology and vegetation (causing vegetation

destruction); the impacts of domestic & process waste water to the surface water

environment.

The main environmental problems during the operation period include: the

impact of the domestic sewage discharge from the staff of each management/service

area to surface water quality; the impact of odor from the mud-dumping area to the

ambient air quality around;

The recognition of the main environmental impacts in different periods of the

project construction is shown in Table 3-2.

3.3 Analysis of Pollution Source

3.3.1 Construction Period

The environment pollution in the construction period of the ship lock

engineering has four main aspects of water, sound, gas and solid waste, the pollutant

generation links of the construction period of the ship lock engineering are shown in

Figure 3-1.

Figure 3-1 Figure of Pollutant Generation Links in Construction Period of Ship Lock Engineering

62


A. Intensity analysis of pollution sources of water environment

The pollution caused by the ship lock engineering includes mainly the domestic

sewage discharged by the construction staff, SS content increase in the water caused

in the excavation, residue water from drying and dewatering of the underwater earth

after being conveyed to the mud-dumping area, oil pollution caused by the

construction machines, etc. The main pollution factors are COD, NH3-N, SS and

petroleum pollutant.

(1) Intensity prediction of domestic pollution sources

The domestic pollution sources are calculated according to the following

formula:

Wi=ACi

In the formula: Wi – discharge amount of pollutant with the serial number of i

(kg/year)

A – man-day of construction site (man-day/year)

By analogy & calculation according to the statistical information from ordinary

local urban area, the amount of domestic water for each person for construction is 100

L/day, and the amount of sewage generated is calculated according to the coefficient

of 0.8, with the COD concentration of 300 mg/L, and NH3-N concentration of 40

mg/L. The total time limit of the Extension Engineering of Yangqiao Ship Lock of

Fenquan River is 24 months (600 working days), and the average number of people at

work is around 200 during the construction period, and the engineering needs 120,000

man-days in total. In the peak period of the construction, people at work is around

300; according to the information above, the calculated amounts of domestic

pollutants generated are shown in Table 3-4, during the construction period, the

amount of domestic sewage generated is 9,600 m³, the amount of COD generated is

2.88 t, and the amount of NH3-N generated is 0.384 t.

63

200 men/d 16m³/ d 4.8kg/d 0.64kg/d

300 men/d 24lm³/d 7.2kg/d 0.96kg/d

(2) Intensity prediction of SS pollution sources

In the excavation of earth above/under water, drainage operation of foundation

pit, drainage for water level reduction by drilling wells, and flushing the aggregate

storage/construction machines or vehicles, large amounts of waste water containing

SS will be generated, affecting the water environment around; the river may become

turbid with the SS concentration rising; the concentration of SS generated during the

construction is about 80 – 160 mg/L.

The underwater foundation construction should be conducted in a dry season,

and adopts the construction technology of cofferdam, after the construction and the

water in the cofferdam standing still for several days, the waste slag from demolishing

the earth rock cofferdam, as well as the stone slurry and sludge from the construction

should be stacked in the spoil ground in a concentrated way, and pouring them into

water is forbidden. The foundations of the bridges adopt cast-in-place piles or spread

foundation by on-site construction or casting. The production waste water in the

cofferdam and the slurry overflowing from the cast-in-place piles have a large amount

of SS which should be deposited in a sedimentation tank, and the deposit shall be

transported to the spoil ground for stacking in a concentrated way.

B. Intensity analysis of pollution sources of atmospheric environment

The main impacts to the atmospheric environment during construction mainly

include: the site leveling, earth excavation& filling and loading/unloading of building

64


materials generate fugitive dust in the construction site, causing the increase of

suspended particulate concentration in the atmosphere around, and intensifying the

local pollution; according to the on-site monitoring in similar construction sites, the

dust concentration near the construction sites can be up to 1.5 – 30 mg/m³, and the

fugitive dust on the road is relevant to the thickness of dust on the ground.

The tail gas from gasoline/diesel engine of construction equipment (like vehicles

and ships) is also an important exhaust gas pollution source, with the main pollutants

of SO2, CO and NO2. The diesel engine of an ordinary ship can generate 1.66 kg/kWh

of NO2and 2.31 g/kWh of SO2. For the gasoline/diesel engine of an ordinary vehicle,

the pollutant discharge coefficients are shown in Table 3-5; generally, the amounts of

pollutants discharged from a diesel engine vehicle, e.g. an 8 t lorry, is shown in Table

3-5.

CO 169.0 27.0 679.25

NO2 21.1 44.4 1116.99

hydrocarbons 33.3 4.44 111.70

C. Intensity analysis of pollution sources of acoustic environment

During the construction period, the noise from the vehicles and machines for the

construction causes adverse impact to the acoustic environment around the

engineering project. The main machines for the construction, including lorries,

bulldozers, excavators, loaders, land levelers, concrete mixers, etc., have the noise

65


level around 78 – 90 dB(A); however, in the sediment dredging & excavating site, the

noise level of the ships, dredging & excavating equipment and mud slurry conveying

equipment is generally around 80 – 100 dB(A). The construction site has some

distance to the living areas on both banks, and the dykes and trees on both banks can

isolate some noise; therefore, as long as the construction time is rationally arranged,

the harm to the environment will not be too great, but the protection should be

enhanced, preventing harm to residents around and the staff on site.

D. Estimation of solid waste

The solid waste during the extension engineering of the ship lock mainly

includes the earth excavated during the engineering, and domestic waste from the

construction staff. The total amount of earth excavated in the engineering is 760.6

thousand m³ (including 24.8 thousand m³ of waste slag from demolishing the old ship

lock and the old management room, and 2.8 thousand m³ of stripped topsoil), the total

amount of earth filled is 257.5 thousand m³, including 114.4 thousand m³ for filling

the main building, and 141.3 thousand m³ for filling navigation walls and berthing

structures. After the reduction of the earth filled, the remaining amount of earth

excavated is 504.9 thousand m³. One part of the remaining earth is used for filling the

cofferdam, and the other part is discarded on the temporarily acquired land as spoil,

and the spoil ground is initially determined to be the bottom land on the southwest

side of the Yangqiao Flood Diversion Gate.

The comprehensive utilization of the spoil and the waste slag can be combined

with the current new rural construction, the waste slag from the oil ship lock can be

used for the construction of rural motor road or the like, and the spoil can be used as

the raw material of a plant for producing bricks and tiles. Before using the temporary

spoil and waste slag, the protection measures against soil and water loss in the

temporary earth stacking area according to the water & soil conservation scheme of

the project.

The Water Bureau of Linquan County approved the location of the waste earth

66


disposal area for Fenquan River Yangqiao lock expansion project, and signed a lease

agreement with Yangqiao Town government (see Appendix).

On the basis of 1.0 kg of domestic waste generated by each person per day, the

number of the construction staff and the time of construction, the total amount of the

domestic waste generated during the construction period is 120 t by calculation.

E. Social environment

(1) Land acquisition

The engineering occupies 16.91 hm2 of land, 6.91 hm2 of land is permanent and

10 hm2 is temporary. The types of occupied land include water, farmland, woodland &

grassland, land for water conservancy facilities, etc. No permanent occupation is

newly added, and temporary land newly added is 10hm2.

(2) Demolition

The engineering relates to demolition & resettlement, and needs to demolish 190

m2 of rural outbuildings, influencing 10 people in 4 households.

(3) Traffic

In the construction of engineering, X017 road will be cut off, which will have an

adverse effect on the travel of the locals.

3.3.2 Investigation & Analysis of Current Status of Pollution Sources

According to on-site investigation, the main pollutants of the Yangqiao Ship

Lock of Fenquan River are discharged from the Ship Lock Management Office with

13 employees currently.

1. Water pollution sources

According to the Quality Standard for Domestic Sewage of Residential Area, on

the basis of 100 L of domestic sewage generated by each person per day in the ship

67


lock, 300 mg/L of COD concentration, and 40 mg/L of NH3-N concentration, the

management office generates 1.3 t sewage per day, and the amounts of COD and NH3-

N generated are 0.39 kg/d and 0.052 kg/d respectively.

2. Atmospheric pollution sources

Some persons of the staff of the Ship Lock Management Office have their meals

in the canteen which uses mainly clean fuels like liquefied gas and electricity, so the

amount of exhaust gas generated can be negligible.

3. Solid waste

The solid waste from the Ship Lock Management Office is mainly the domestic

waste generated by the ship lock management staff; on the basis of 1.0 kg of domestic

waste generated by each person per day, 13 persons working in the ship lock generate

13 kg of domestic waste per day, which are sent to the department for city appearance

and environmental sanitation for unified disposal.

3.3.3 Intensity Analysis of Pollution Sources of Ship Lock in Operation Period

A. Intensity analysis of pollution sources of water environment

The pollution during the operation period is caused mainly by the domestic waste

from the staff of the ship lock and the operating ships, as well as the oil from the

ships; the main pollution factors are COD, NH3-N and petroleum pollutants.

1. Intensity prediction of pollution sources from the staff of the ship lock

The project has a Ship Lock Management Office with 13 employees, According to the

Quality Standard for Domestic Sewage of Residential Area, on the basis of 100 L of

domestic sewage generated by each person per day in the ship lock, the COD

concentration is 300 mg/L, and NH3-N concentration is 40 mg/L. After the treatment

of a buried sewage treatment device, the sewage should meet the requirements of

Grade II in Table 4 of Integrated Wastewater Discharge Standard (GB8978-1996); the

68


discharge amount of sewage is 429 t/a, and the discharge amounts of COD and NH3-N

are 64.4 kg/a and 10.7 kg/a respectively. The predicted results of the domestic

pollutants generated and discharged by the staff of the ship lock are shown in Table 3-

6.

2. Intensity prediction of pollution sources from ships

a. Prediction of oil pollution amount of ships

In order to improve the technical level of ships for inland water transport,

improve the structure of such ships, keep the transport safety of the ships and prevent

the water pollution caused by the ships, on October 11, 2001, the Ministry of

Communications issued Standardized Administration Regulations on Ships for Inland

Water Transport, which came into effect on December 1, 2001; the Regulations forbid

the ship having an outboard motor with total length over 20 m to conduct inland

transport. The National Essentials on Standardized Development of Ship Types for

Inland Water issued by the Ministry of Communications on February 16, 2006 put

forward the overall target for the standardization of ship types for inland water

explicitly, and the ships having outboard motors will be gradually forbidden to travel

on the inland river. The prohibition of the ships having outboard motors on the inland

river can effectively reduce water pollution accidents (like water leakage) and the

noise along the channel; the efficiency of the ship lock can be improved and the rate

of safety accidents on water can be reduced; in general, the prohibition has good

economic & social benefits.

69


Administrative Regulations of People’s Republic of China on Prevention and

Control of Environmental Pollution of Inland Waters Caused by Ships (Decree of

Ministry of Transport (2005) No. 11) stipulates: “Ships discharging pollutants shall

meet the relevant national and local standards and requirements about pollutant

discharge. The pollutants from the ships, which do not meet the discharge standards

and requirements, shall be disposed by entrusting qualified pollutant reception units,

and shall not be discharged arbitrarily.” The “Decree No. 11” also stipulates: when a

ship is discharging sewage for ballast or washing the ship’s hold, the sewage in the

engine room, residue oil, oily sewage or other residue matters, the ship shall firstly

report to the maritime administrative authorities according to relevant regulations and

obtain approval. According to the requirements of port & shipping administrative

authorities, a ship shall not discharge oily sewage in the bottom of the ship’s hold into

the water when it is passing a ship lock. Therefore, the normal process for a ship

passing the ship lock does not cause severe oil pollution in the water.

b. Intensity prediction of domestic pollution sources of ships

The Administrative Regulations of People’s Republic of China on Prevention and

Control of Environmental Pollution of Inland Waters Caused by Ships stipulate:

“Ships shall arrange treatment devices or storage containers adapted to the amount of

domestic sewage generated according to regulations. No ship shall discharge domestic

sewage into the inland water if the sewage does not meet the standards for discharge.”

The time for a ship passing the ship lock is short (the ship lock opens 35 times per

day, 36 min each. The total open time of the ship lock is 21 hours), so in the

assessment, on the basis of the population equivalent of 20 and 100 L/d of sewage

generated per person, the sewage generated should be 2.0 m³/d; if 50% of the sewage

is discharged, the amount of the sewage discharged should be 1.0 m³/d. The discharge

of domestic sewage from the ships follows the relevant requirements in Effluent

Standard for Pollutants From Ship, and the discharge of micro amount of sewage

according to the standard has limited impact to the water environment, and it will not

70


assessed in the assessment. It is recommended that the port & shipping administrative

authorities should enhance administration, forbidding the ships to discharge domestic

sewage to the water when they are passing the ship lock normally.

B. Intensity analysis of pollution sources of atmospheric environment

During the operation period, the exhaust gas pollutants are mainly the exhaust

gas (containing SO2 and NO2) from the operation of the engines of the ships, and a

little of exhaust gas (like oil fume) from the domestic facilities of the Ship Lock

Management Office. The time for a ship waiting for ship lock opening is about 0.6

hour, and the engine does seldom run during the time; the exhaust gas is mainly

generated when the ship is moving on the upstream & downstream approach channels

(full length 965 m). The amount of the exhaust gas discharged from the ships is

calculated in the method recommended by the Lloyd's Register of Shipping; in 2010,

the discharge amount of atmospheric pollutant NO2 discharged from ships passing the

ship lock was 0.21 kg/d (69.3kg/a), and for SO2, the amount was 0.29kg/d (95.7kg/a).

With the science development and the promotion of advanced technology, and the

improvement of standard requirements for the exhaust gas discharge, the ships for

inland water will be more environment-friendly and energy-saving in the future, and

the atmospheric pollutants discharged will be less. The ship lock has only a few of

staff members, adopts clean fuels like liquefied gas, and has no facility like a boiler;

therefore, the amount of exhaust gas generated can be negligible.

C. Intensity analysis of pollution sources of acoustic environment

The noise sources of a ship entering or leaving the ship lock are mainly engine

noise (including the noise from discharging exhaust gas) and horn. In the operation,

the noise in 5 m range from the sound source can achieve 80 – 90 dB(A); such

devices producing noise are continuous steady-state linear noise sources which cause

adverse influences to the residents on the banks, and it is predicted that the noise in 20

m range (at day) or 50 m range (at night) from the channel can meet the Class 2

standard of Environmental Quality Standards for Noise (GB3096-2008); Wanggao

71


Village, the only sensitive point of the project, is over 50 m away from the channel.

With the science development and the promotion of advanced technology, the ships

for inland water will be more environment-friendly and energy-saving in the future,

and particularly, with the gradual elimination of ships having outboard motors, the

noise along the channel will be greatly reduced.

D. Estimation of solid waste

The solid waste generated during the operation period includes mainly the

domestic waste generated by the ship lock management staff and the staff on ships; on

the basis of 1.0 kg of domestic waste generated by each person per day, 13 persons

working in the ship lock generate 4,290 kg/a of domestic waste, which are sent to the

department for city appearance and environmental sanitation for unified disposal.

For the domestic waste generated by the staff on ships, the Administrative

Regulations of People’s Republic of China on Prevention and Control of

Environmental Pollution of Inland Waters Caused by Ships stipulates explicitly: “No

waste from a ship shall be discharged to inland water. The waste from a ship must be

received and disposed by a qualified unit.” Therefore, such domestic waste will not be

calculated in the assessment. The ships shall be equipped with waste containers with

caps, and without leakage or overflow; also, the waste can be collected into bags, and

the generated waste is sorted, collected and stored to meet the requirements of the

ships for storing waste during the travel. No non-degradable disposable foam plastic

tableware shall be used. The domestic waste from sailors shall be placed in the

dustbins on the ship, and be disposed by entrusting a waste disposal agency in a city

along the channel after the ship reaches the destination.

E. Summary of pollutants of ship lock engineering

The summary of pollutant change in the operation period of the project, i.e. the

extension engineering of the ship lock, is shown in Table 3-7.

The pollution sources include mainly the

domestic sewage discharged by the

construction staff, SS content increase in

the water caused in the excavation,

residue water from drying and

dewatering of the underwater earth after

being conveyed to the mud-dumping

area, oil pollution caused by the

construction machines, etc. The main

pollution factors are COD, NH3-N, SS

and petroleum pollutant; in the

excavation of earth above/under water,

drainage operation of foundation pit,

drainage for water level reduction by

drilling wells, and flushing the aggregate

storage/construction machines or

vehicles, large amounts of waste water

containing SS will be generated,

affecting the water environment around;

the river may become turbid with the SS

concentration rising; the concentration of

SS generated during the construction is

about 80 – 160 mg/L.

The sewage water mainly includes the sewage from

land and the domestic sewage from ships, the

domestic sewage amount in the service area is

about 429 t/a, with the main components of COD

(concentration 300 mg/l), ammonia nitrogen

(concentration 40 mg/l), etc.; for the domestic

sewage from the sailors during the travel of a ship,

local maritime authorities are required to enhance

administration, if so, the discharge according to the

standards can be generally achieved, and the

pollution of Fenquan River caused by the domestic

sewage from sailors can be prevented; in addition,

it is possible that problems like oily ballast sewage

occur during operation, so it is recommended that

the local maritime authorities shall enhance

administration; once there is the sewage for ballast

or washing the ship’s hold, or oily sewage on the

Pollution


Atmospheric

pollution

source

The exhaust gas is mainly from the

smoke discharged from the vehicles and

machines for construction due to fuel

combustion, odor from the contaminated

sediment from the site and the sediment

dumping area, windblown dust of lime

and cement on the construction site, and

fume from the stoves for the livelihood

of the employees.

The exhaust gas pollutants are mainly the exhaust

gas (containing SO2 and NO2) from the operation of

the engines of the ships. The time for a ship waiting

for ship lock opening is 0.6 hour, and the engine

does seldom run during the time; the exhaust gas is

mainly generated when the ship is moving on the

upstream & downstream approach channels (full

length 965 m). The amount of the exhaust gas

discharged from the ships is calculated in the

method recommended by the Lloyd's Register of

Shipping; in 2010, the discharge amount of

atmospheric pollutant NO2 discharged from ships

passing the ship lock was 0.21 kg/d (69.3kg/a), and

for SO2, the amount was 0.29kg/d (95.7kg/a). The

ships for inland water will be more environment-

friendly and energy-saving in the future, and the

atmospheric pollutants discharged will be less.

75


Pollution


Noise pollution

source

The noise pollution sources are inevitable

during the construction of the

engineering, including the vehicles and

machines for construction, like lorries,

bulldozers, excavators, loaders, concrete

mixers, etc., and their noise level is

around 78 – 90 dB(A). However, in the

sediment dredging & excavating site, the

noise level of the ships, dredging &

excavating equipment and mud slurry

conveying equipment is generally around

80 – 100 dB(A).

The noise sources of a ship entering or leaving the

ship lock are mainly engine noise (including the

noise from discharging exhaust gas) and horn. In

the operation, the noise in 5 m range from the

sound source can achieve 80 – 90 dB (A); such

devices producing noise are continuous steady-state

linear noise sources which cause adverse influences

to the residents on the banks. With the science

development and the promotion of advanced

technology, the ships for inland water will be more

environment-friendly and energy-saving in the

future, and the noise emitted will be greatly

reduced.

Solid waste

The solid waste comes mainly from the

waste from the construction ships, the

domestic waste from the construction

staff and construction waste, which are

all general solid waste.

The solid waste generated during the operation

period includes mainly the domestic waste

generated by the ship lock management staff and

the staff on ships; on the basis of 1.0 kg of

domestic waste generated by each person per day,

13 persons working in the ship lock generate 4290

kg/a of domestic waste, which are sent to the

department for city appearance and environmental

sanitation for unified disposal. The domestic waste

from sailors shall be placed in the dustbins on the

ship, and be disposed by entrusting a waste

disposal agency in a city along the channel after the

ship reaches the destination.

include wheat, soybean, corn, sorghum, sweet potatoes, cotton, etc.

81


2. Vegetation

The trees in the assessed area are mainly broad-leaved trees, and the project area

has a variety of trees for greening, including mainly the broad-leaved trees like locust

trees, Chinese toons, Ulmus pumila, mulberry, Italian poplar trees, willows, Chinese

parasol trees, oriental plane trees, etc., and needle-leaved trees like slash pines, cedars,

oriental arborvitae, etc.; the fruit trees include plum trees, peach trees, apricot trees,

cherry trees, persimmon trees, etc.; phytocoenosiums like reeds and weeds are

distributed in low and wet bottom lands along the banks of the river, and the

remaining natural trees, bushes and herbaceous plants are mainly the ones belonging

to the plantage of North China. No damage of the crops and trees in the assessed area

was found, the plants grow well, and the biomass is normal. In the aspect of plant

growth, the current status of the ecological environment quality of the assessed area is

good.

Most of the project area is upland crop area, a farmland ecosystem formed by

early ploughing and ripening of human, so most wild plants grow in a scattered way,

and are distributed in fields, forest network, roadsides, places beside ditches and

beach lands. In the investigation, no national and provincial protected wild plant was

found, and the wild plants in the assessed area include terrestrial herbaceous plants,

terrestrial ligneous plants and aquatic herbaceous plants.

3. Wild animals

The project is located in Huaibei Plain, and the vegetation in the area includes

mainly crops (wheat, soybean, corn, etc.) and artificial vegetation (like trees beside

villages/roads/water/residences). In such an ecological area with simple composition

and simple structure, the varieties of animals are few. According to in-site

investigation and the analysis of existing information, no national or provincial

protected and endangered wild animal was found in the area for assessment.

According to the information from investigation, in the flora composition of the

82


wild animal in the area, the found amphibians belongs to 2 species in 2 genera, 2

families, 2 orders, the found reptiles belong to 1 species in 1 genus, 1 family, 1 order,

for birds, 11 species in 11 genera, 9 families, 5 orders, and for mammals, 8 species in

8 genera, 5 families, 4 orders. Most of the birds are summer birds as the basic bird

population in the area. For mammals, the rodents take advantage, and the dominant

populations include large amounts of sewer rats, Mus musculus and grass hares.

Apodemus agrarius likes living in secluded bottom lands and water with sufficient

food, which is hardly seen in the dry farming area. As the natural enemy of mice,

there are a large number of yellow weasels in the area, and they are significant for

maintaining ecological balance, and developing crop production, forestry and animal

husbandry. In addition, toads and frogs also exist in the area. In summary, the varieties

and amounts of the wild animals are small, and the dominant populations include

birds and rodents.

4.2.2 Current Status of Aquatic Environment

The dominant populations of phytoplankton in the channel of Quan River

include blue-green algae and diatom; aquatic plants include silver grass, reeds, lotus,

cattails, water chestnuts and algae, and aquatic vascular plant species also includes

Potamogeton wrightii, Vallisneria natans, etc. The main planktonic animal is Rotifera,

a kind of protozoa, and the other dominant populations are amoebas, askencsia,

Difflugia globulosa, Trinema enchelys, etc. In rivers and ditches, the benthonic

animals are mainly corbiculae and snails, and large amounts of tubificidae and

chironomidae larvae are reproduced. There are tens of kinds of fishery resources,

including mainly carps, silver carps, cruises, mandarin fishes, grass carps, catfishes,

prawns, crabs, etc., and the main fishes for trade are cyprinid fishes.

No fish spawning ground was found in the on-site investigation. According

4.3 Social Environment Overview

4.3.1 Administrative Division

LinquanCounty is located in the Northwest of Anhui Province, it borders on

FuyangCity, JieshouCity and Fu’nan County in the east, northeast and southeast, and

in the directions of west, northwest and southwest, it borders on the counties and

cities of HenanProvince, including Shenqiu, Xiangcheng, Pingyu, Xincai, Huaibin,

etc. The county governs 21 towns, 10 villages and one industrial park; with the total

area of 1,818 km2 and total population of 2.31 million, it is the county with the largest

population in China’s Mainland.

4.3.2 Social & Economic Development

In 2012, the county achieved the total output value of RMB 11.6 billion,

increased by 13%, the fiscal revenue of RMB 0.78 billion, increased by 22%, the

fixed asset investment (with certain scale) of RMB 4.7 billion, increased by 30%, and

the total customer goods retail sales of RMB 5.8 billion, increased by 21%; in

financing institutions, the deposit balance is RMB 21.81 billion, increased by RMB

3.46 billion compared with the beginning of the year, the loan balance is RMB 6.11

billion, increased by RMB 0.48 billion compared with the beginning of the year. The

county has the total industrial output value (above certain scale) of RMB 8.5 billion,

increased by 31.5%, the industrial added value of RMB 1.8 billion, increased by

23.3%, and the industry sales value of RMB 8.9 billion, increased by 36.8%; the

sales-output ratio achieved 104.7%, and the comprehensive industrial benefit index

was 261%. The backbone enterprises have further development; there are 21 new

enterprises with certain scale, and 80 enterprises above certain scale in the County.

Taking the opportunity of strategic cooperation, Zhongneng Chemical of Jincheng

Anthracite Mining Group and Wenwang Company expanded their production scales

comprehensively, and made new historical records of output value and profit tax. The

construction of the industrial park of the county was accelerated, 8 standard factories,

85


3 employee apartments and one comprehensive building were completed and come

into use; the first-stage, second-stage and third-stage projects of Xinquan Garden had

454 households of people resettled, and the main bodies of the first and second tender

section projects of Daiqiao Resettlement Area were completed. In the industrial park

of the county, 14 projects were started in 2012, 24 were in construction, 14 new

enterprises began their production, and there were 82 enterprises in production. The

infrastructure and supporting facilities of Tongcheng Leather Industrial Park, the

Dehydrated Vegetable Industrial Park and the Quanbe Food Industrial Park were

gradually being perfected.

There is no railway in Linquan County, and the main traffic routes of the county

include the Provincial Road 102 through the county in east-west direction, and the

Provincial Road 204 through the county in north-south direction.

The main service object of the project is Anhui Jinmei Zhongneng Chemical

Industry Co., Ltd.

Anhui Jinmei Zhongneng Chemical Industry Co., Ltd. (former Linquan

Chemical Co., Ltd, Anhui) originates from Linquan Chemical Fertilizer Plant founded

in 1970, the enterprise had shareholding reform in 1994, and was reconstructed as a

private enterprise; in the beginning of 2007, the company began its cooperation with

the Jincheng Anthracite Mining Group of Shanxi by joint venture, and currently, the

company is a comprehensive coal chemical enterprise integrating chemical fertilizer,

chemical industry and combined heat & power generation; the company ranks Top 50

in Chinese nitrogen fertilizer enterprises, Top 500 in Chinese chemical enterprises and

Top 100 in Anhui enterprises. Currently, the company occupies 1,500 mu of land, has

total asset of RMB 2.8 billion, over 2,000 employees, the annual operation revenue of

RMB 2.5 billion, and the profit tax of RMB 0.2 billion. The annual production

capacity of units includes one million tons of alkamine, one million tons of urea, 0.3

million tons of methyl alcohol, 0.18 million tons of hydrogen peroxide, 0.1 million

tons of compound fertilizer and 0.1 million tons of ammonium bicarbonate. The

86


registered trademark “Quanhe” of the company is honored as the famous trademark of

Anhui Province; the leading product of the company, “Quanhe” urea, is a famous-

brand product of Anhui province, which is sold well throughout China and foreign

countries including Vietnam, Malaysia and Australia.

Since the increase of capital and shares, the strength of Anhui Jinmei Zhongneng

Chemical Industry Co., Ltd. (former Linquan Chemical Co., Ltd, Anhui) is improved

continuously, it needs to import a large amount of coal every year, and meanwhile,

export large amounts of chemical fertilizer and other chemical products. Since

Linquan has no railway, under the limitation of Yangqiao Ship Lock, the imported

coal from Shanxi can only be unloaded from train in Jieshou, and transported to the

company by trucks on Provincial Road 204; the exported goods can only be

transported to the position under the Yangqiao Ship Lock through Provincial Road

102, and transported to Jiangsu, Zhejiang and Shanghai through Shaying River and

New Cihuai River.

Therefore, Provincial Roads 204 and 102 have excessive road transportation

pressure, the long-term overload of the roads causes poor road condition. In addition,

due to the travel of the vehicles, and the inevitable sprinkling of goods, residents on

roadsides suffer from the environmental impact like noise and dust, and the

transportation cost is increased. In recent years, Linquan County enhanced the

invitation of investment, a large amount of enterprises invest in Linquan, the

transportation cost needs to be reduced by water transport. Therefore, it is necessary

to construct the engineering project.

4.3.3 Current Status of Cultural Heritage

The term "cultural heritage" of UN includes the positions having archaeological

(prehistoric), paleontological, historical, religious and unique natural value. Therefore,

according to the Business Manual of World Bank, the cultural heritages not only

include the heritages of ancestors (e.g. ruins, shrines and battlefields), but also unique

natural landscapes, including valleys and waterfalls.

87


According to the investigation, Linquan County has one provincial key cultural

relic, and 11 county (city/district) key cultural relics; there is no key cultural relic or

cultural heritage was found in the area influenced by the engineering of the project.

5.2.2 Assessment of Current Status of Environmental Quality of Surface Water


According to the function zoning of water environment of Anhui Province and

the confirmation letter of Fuyang Municipal Environmental Protection Bureau for the

standards, for the surface water quality of Fenquan River, the Class IV water quality

standard of Environmental Quality Standards for Surface Water(GB3838-2002) is

executed [for SS, the standard limiting values for aerobic soil crops in Standards for

Irrigation Water Quality (GB 5084-2005) are executed], and the standard values are

showed in Table 1-3 of the Statement.

95


2. Assessment method

The confirmed functional water quality standards are compared with the actually

assessed concentration of the factors in the water assessed, and single pollution index

method is used for calculation so as to analyze the environmental quality and the

pollution degree of the water, indicating that whether the water meets the determined

functional requirements for water quality.

According to the stipulations of Technical Guidelines for Environmental Impact

Assessment (HJ/T2.3-1993), if the standard index of a water quality parameter < 1, the

water quality parameter does not exceed the stipulated water quality standard, and the

water quality can meet the functional requirements for use in monitoring; if the

standard index of a water quality parameter > 1, the water quality parameter exceeds

the stipulated water quality standard, and the functional requirements for use cannot

be met in monitoring.

3. Assessment indexes

In combination with the status of surface water environment monitoring, the

assessment selected 8 of 9 monitoring factors except DO as assessment indexes (the

DO values in all sections can meet the requirements of the standard).


The assessment results of the environmental quality of surface water (single factor

index Si) are shown in Table 5-7

According to current status monitoring, the assessment results of the current

status of the surface water are as follows:

In all sections, the monitoring factors of pH, DO, petroleum pollutants and faecal

coli bacillus can all meet the requirements of Class IV water quality standard of

Environmental Quality Standards for Surface Water(GB3838-2002); SS can meet the

97


requirements of standard limiting values for aerobic soil crops in Standards for

Irrigation Water Quality (GB 5084-2005); however, in all of the three sections, both

monitoring factors of total nitrogen and total phosphorus exceed the standard, the total

nitrogen exceeds the standard for 2.69 times to the maximum extent, and total

phosphorus exceeds the standard for 0.57 times to the maximum extent; the

monitoring factors of COD and BOD5 slightly exceed the standard slightly in 1#

Monitored Section, and according to investigation & analysis, such standard

exceeding is mainly caused by the domestic sewage discharged into Fenquan River

from the urban residents along the river.

The monitoring results show that the current status of the values of Fenquan

River cannot meet the requirements of Class IV water quality standard of

Environmental Quality Standards for Surface Water (GB3838-2002).

5.3 Monitoring & Assessment of Current Status of Acoustic

Environment

5.3.1 Current Status Monitoring

and Table 5-11, all monitoring items of the sediment are less than the standard values

of Grade II. After stacking and naturally drying the sediment in the mud-dumping

area, the area can be returned to greenbelt, or used for the construction of protection

forest, and the heavy metal contents of the land will not affect the growth of plants

and the health of human.

5.5 Environment Status of Fuyang City

According to the environmental status bulletins from 2008 to 2011, in 2008 and

2009, the water quality of Quan river was heavy pollution (Class V Inferior), and that

in 2010 and 2011 is light pollution (Class IV), meeting the plan requirement of Class

IV.

The environmental quality status of QuanRiver in 2011: 4.17% of water has the

quality of Class III, 45.83% of water has the quality of Class IV, 25.00% of water has

the quality of Class V, and 25.00% of water has the quality of Class V Inferior).

Compared with the quality in 2011, the water quality proportion of Class III was up

by 4.2%, and the water quality proportion of Class V & Class V Inferior was down by

8.3%. The main pollutants are permanganate index, BOD and petroleum pollutants.

The Air Quality Grade of the urban area of Fuyang is Grade II, the air quality is

Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 6. Scheme Comparison

6. Alternative Analysis

Since the engineering is extension, in the principles of reuse and minimizing land

acquisition &demolition, the position of the ship lock is the original position of the

old ship lock. According to the landform environment around the old ship lock whose

right side is only 120 m away from the Yangqiao Check Gate, considering the

navigation clearance for bridges and the longitudinal slopes of road connection lines,

the center of the ship lock cannot be arranged to the right further; the interior of the

dyke on the left side is an administrative village, if the center is arranged to the left

too much, not only the dyke needs to be demolished and rebuilt, but also land

acquisition and demolition are required. According to the terrain and the change of

ship lock size, the center of the newly built ship lock is arranged on the left side of the

original one about 2.8 m away (namely, 2.8 m northeastern of the central line of the

original ship lock).

Scheme I: the longitudinal center line of the ship lock on the left of the center of

the original ship lock with the distance about 2.8 m, and is generally parallel with the

center line of the water flow direction of the check gate. The main body engineering

of the ship lock is in the upstream of the check gate, the road bridge is across the tail

bay, and the approach channels are asymmetrically arranged. Scheme II: the position

and the road connection lines of the scheme are the same as those in Scheme I, and

the difference is that the approach channels are antisymmetrically arranged

The advantages of Scheme I include: the approach channels fully utilize the

original channels, requiring only small amount of dredging work; the interference to

the existing dykes is small and the total investment is less. The disadvantages of

Scheme I include: the asymmetrical arrangement causes short partition dyke in the

middle of the upstream, so solid berthing structures need to be built as partition dykes.

The advantages of Scheme II include: the partition dyke in the upstream is slightly

104


longer than that in Scheme I, and the water flow condition in the approach channels is

better; the disadvantages include: a long retaining wall is required on the left bank of

the upstream approach channel so as to prevent demolishing the dyke, the

construction causes more influence to the existing dykes, and the total investment of

the engineering is more.

In summary, the FSR recommends Scheme I

impact to the soil environment; Scheme I does not need dyke expansion or land

acquisition, and has less land occupation, so the impact to ecological environment can

be reduced; in addition, Scheme II relates to land acquisition & demolishment, and

has greater impact to the environment of the sensitive point in comparison with

106


Scheme I; the estimated investment of Scheme I is less than that of Scheme II for

Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 7. Environment Impact Evaluation

7 Environmental Impact Evaluation

7.1 Social Environment Impact Evaluation

7.1.1 Population Health Impact Analysis

The project area is not the harder-hit area of endemic disease and it shall abide

by the principle of prevention first; before the construction team mobilize the site,

they can ask about the local endemic diseases to the local medical department, and

after carrying out prevention measures with the guidance of the department, endemic

disease will not have any impact to the construction workers.

For the prevention of infectious disease, it mainly depends on the cultivation of

good health habits of the construction workers by telling necessary blood flukes

prevention knowledge and hygienic knowledge, paying attention to dietetic hygiene

and taking necessary blood flukes prevention measures; thus, the infection and

development of infectious disease can be controlled.

7.1.2 Analysis of regional traffic impact

The project is involved with demolishing of old roads and bridges as well as

building of new roads and bridges. In the construction of bridges, the interruption of

X107 may impose some impact on regional traffic and public transportation. In order

to minimize the adverse effects of construction on public transportation, construction

sidewalks shall be set in the lock downstream in the construction period, so that

pedestrians and small vehicles can use the temporary downstream sidewalks for

transportation or travelling, while large vehicles can bypass the construction area

through S204 or S328. Because this kind of effects is temporary and the newly built

roads can improve public transportation after the end of the construction, the

temporary adverse influence is acceptable. The schematic of the construction sidewalk

108


layout is shown in Figure 7-1.

To avoid traffic jam during the construction, the construction unit shall post a

notice about the road works, telling the vehicles to select roads or detour depending

on the situations or pass through the construction road to reduce the traffic pressure

during construction; meanwhile, set related signs, labels and temporary signal lights

in road junctions; during the bridge construction, the construction vehicles will be

mixed with social vehicles together, so the bidder shall carry out the safety

management work on the construction vehicles to avoid any potential traffic danger.

In general, the impact of bridge construction to regional transportation reduces to

the minimum level by reasonably arranging construction timing sequence, carrying

out transport broadcasting prior to the construction and setting billboard in the

construction site.

Figure 7-1 Schematic of the construction sidewalk layout

7.1.3 Other Social Environment Impact Analysis

The adverse impact to social environment in the construction period is also

LegendConstruction Sidewalk

Coffer

Road & Bridge for Route Change

109


reflected in the following aspects:

(1) Construction noise's impact to social environment

If the construction is in hot summer, and many people have the habit of taking a

noon break when they are more sensitive about noise; the construction noise make

some residents hard to take their noon break, which will influence their normal life.

(2)External construction workers' impact to the society

The increase of external construction workers whose lifestyle has major

difference with the local residents, might lead to conflict or theft; the public security

has potential unstable elements.

(3)Impact of sludge odor

The excavated sludge from the construction stinks, which upsets the residents

nearby, attracts flies and mosquitoes and influences the sanitary environment near the

project.

(4)Impact of fugitive dust in construction on social environment

Fugitive dust in construction (including road dust during vehicle operating,

loading and unloading) will influence the local environmental air quality and people's

life; it is not good for "open-window ventilation" and influences the life and work of

residents nearby.

In short, these impacts are temporary and will end with the completion of the

construction period; on the other hand, the construction unit shall strengthen the

training to the construction workers and publicity about the construction process to

the residents nearby to fully understand this project and the construction workers and

that the construction will not have long-term and significant impact to the living

quality of local residents.

110


7.1.4 Social Environment Mitigation Measures

A.Measures for mitigation of traffic impact

In order to effectively engineering construction's influence to the traffic, the

following measures shall be taken:

(1) Rational setting of construction road

Shall use the existing country road as far as possible, and appropriately

reinforce the pavement and drainage system;

Shall consider it as the road for villagers around when new roads are planned

to be built;

The damaged road caused by construction vehicles shall be timely repaired

to make sure the good shape of road condition. The narrow road section can be

broadened with the help pf road plans.

The setting of construction road shall be reviewed/approved by the

environmental supervision engineer.

(2) Construction design and scientific management

The construction unit shall post a notice about the road works, telling the

vehicles to select road or detour depending on the situations;

Increase signs, plates and temporary signal lights on the intersections during

the construction period;

During the bridge construction period, the construction vehicles and social

vehicles are mixed together on the road, so the construction unit shall well

manage the construction vehicles to avoid transportation safety hidden danger;

Arrange the construction procedures in a scientific manner during the

construction design, accelerate the bridge construction schedule, and reduce the

construction's impact to the traffic;

For the engineering transportation vehicles, strengthen the traffic dispatch

111


and management, choose reasonable traffic lines, avoid rush hour, and reduce the

jam caused by construction vehicles.

(3) Multi-sectoral coordination

In design and construction stages, the construction unit shall negotiate with the

local government to get their support, reasonably shunt the vehicles and pedestrians

and make the traffic problem solved during the construction period administratively.

(4) Strict site management

Strictly manage the site and draw a clear line of construction site boundaries,

reasonably pile the muck, sand, stone and materials, reasonably park the vehicles and

machineries, and reduce traffic barrier. Also, set temporary road and warning signs,

and have specially-assigned person to guide the traffic.

(5) Education to related personnel

Educate the construction workers not to obstruct the surrounding traffic.

Strengthen driver education, strictly forbid the overload, and timely clean the

scattered materials.

B. Population health protection

1. Construction area clean-up

At the early stage of construction period, carry out the cleaning and disinfection

work of the construction camps, level the site, use phenol drug use motor sprayer to

disinfect the toilets and garbage heap on the construction camp, and clean the solid

waste.

During the construction period, carry out deratization, mosquito eradication and

fly eradication activities in the construction range to reduce infectious vector and cut

the pathophoresis route. Especially the deratization work shall be strengthened, which

shall be carried out once a quarter. Use miehailin aerosol to exterminate flies, twice a

year.

2. Food hygiene management and supervision

112


Regular food and hygiene inspection and supervision to the construction area

must be conducted; the kitchen staff must have hygiene license to do their job, the

ones who have access to food must have "health certificate"; if any food poisoning,

effective control measures must be taken to prevent source of the disease from

expansion.

3. Health and epidemic prevention

The construction workers must have physical examination before they get into

the site, and if there is any new-entry infectious disease, the patient must be

quarantined to cut off the route of transmission; in the second year, carry out physical

examination to 20% of construction workers to know their health conditions and

prevent prevalence of diseases. Set medical aid post in the place with relatively

concentrated construction workers, equipped with commonly used drugs to carry out

simple treatment and first aid of occupational injury.

The constructor and engineering management department in the construction

area shall have a health and epidemic prevention duty officer to manage the health

and epidemic prevention in the range and carry out the food and hygiene publicity and

education to the construction worker to improve their consciousness to prevent

diseases.

7.2 Water Environmental Impact Evaluation

7.2.1 Water Pollution Impact during Construction Period

1. Water pollution impact during ship lock construction period

(1) Production wastewater

The production wastewater discharge during the ship lock construction period

includes that in the process of underwater construction, the piling, well drilling,

pumping and other construction activities will make the suspended matter content in

the surface water to increase; the dripping and leaking sump oil from the construction

machinery and the oily wastewater generated after the open-air machinery washed by

113


rain; the bilge oil in the construction ships; the pollution caused by the stacked

building materials, wastes washed by rain or leaching water; and the foundation pit

drainage and construction sand washing wastewater. Among the generated various

production wastewater, the main pollutants are suspended matters and petroleum.

According to the status monitoring results, the water quality of Fenquan River

cannot reach the corresponding water body function requirements; its water quality is

poor, the water flows slowly, and the river's self-cleaning capacity is low. The peak

period of the engineering construction is often in dry season, so the discharge of

production wastewater will have certain pollution to the ship lock river reach.

Suspended matter influence: for the underwater dredging work of the ship lock

engineering design part, due to the cutter-suction agitation can lead to the re-

suspension and spreading of the bottom sediment of local waters; compared to other

underwater dredging work instances, the SS concentration in the water area 15m from

the cutter-suction dredger rimer center clearly increases, the rates of release of N and

P pollutants are 1~2 times higher than the ones in condition of rest, and the water

environmental impact outside the 15m range is not very obvious. Therefore, in the

bottom sediment dredging process in the construction period, SS's impact to the water

quality of Fenquan River is limited.

Impact of petroleum: The petroleum content in construction machinery and

vehicle washing waste water. The oily wastewater is directly discharged to the water

body and forms a layer of oil film on the surface, leading to the uneasiness to recover

dissolved oxygen in the water and thus influencing the water quality; the random

discharge of oily wastewater will reduce the soil fertility, change soil structure and go

against the construction slash recovery.

Therefore, in order to prevent surface water pollution, it is suggested to set

temporary oil removal wastewater settling pond to collect the various washing

wastewater, leaching wastewater and foundation pit drainage in the construction

process; re-use the wastewater as a part of construction water after settling it. The

114


deep well construction pumped water is collected in a water collection and settling

pond and then discharged to the channel in two sides through the general trench. The

management to construction ships shall be strengthened to avoid or reduce bilge oil

leakage. The implementation of above measures can effectively avoid or relieve the

pollution to surface water.

(2) Domestic wastewater

According to the engineering analysis in Chapter III, the discharge value of

domestic sewage during the construction period shall be 16~24m3/d. The main

pollutants in domestic sewage are COD and ammonia nitrogen; there is not so much

domestic sewage and the sewage discharge will not change the water functional

category of Fenquan River surface water and have little impact to the water quality.

But due to domestic sewage water quality exceeds the discharge standards, it will has

adverse impact to residents' health. The evaluation requires the construction workers

to have centralized residence and centralized discharge of domestic sewage. But after

setting septic tank outside the residence of the construction workers, and send the

feces to farm fields for fertilizer after primary treatment on a regular basis.

2. Water pollution impact during construction period of highway bridge

reconstruction and cable engineering

The bridge and wiring works have short construction period and small total

volume sewage, and the wastewater will stop with the completion of the construction

period; the pollution sources are mainly COD, BOD5, SS and petroleum, and the

construction machinery overhaul flushing water contains petroleum pollutants and

shall have deoiling treatment. The cofferdam built before the underwater construction

shall be removed after the completion of the underwater construction and several days

of water settling in the cofferdam. The construction wastewater shall be settled,

deoiled and treated with innocent treatment facilities and temporary toilet septic tank

based on different construction areas, and transported to the farm fields or forests

nearby.

115


3 .Bottom sediment environmental impact analysis

The Fenquan River bottom sediment environment current situation evaluation

results indicate that the contents of heavy metal pollutants in the bottom sediment of

the working area are all lower than the Grade 2 standard in Control standards for

pollutants in sludges from agricultural use (GB4284-84). After being stacked and air

dried, this part of bottom sediment can also be used in cultivated land or the

construction of protection forest, and its heavy metal content will not influence

vegetation growth or human health. But the discharge of bottom sediment leachate

might contain a small trace of heavy metal, and its content is basically in direct

proportion to the heavy metal content in the bottom sediment at the beginning of

leaching process; the heavy metal content of bottom sediment is low, so the heavy

metal content in leachate; therefore, the leachate has very little influence to ambient

soil and water body. Therefore, the single factor indexes of heavy metals in the

Yangqiao Ship Lock channel bottom sediment are all low, and the heavy metal and

leachate in the bottom sediment shall not have significant influence to soil and

groundwater.

7.2.2 Environmental Protection Measures in the Construction Period

The sewage during the engineering construction mainly comes from the gravel

washing wastewater, construction machinery, vehicle washing wastewater and

construction period domestic sewage. You need to take measures to the above

wastewater to prevent the pollution of construction wastewater and domestic sewage

to waters nearby. For sewage discharge, execute according to Integrated wastewater

discharge standard (GB8978-1996).

A) Gravel washing wastewater

Due to the drainage of gravel washing water in building construction is not

discontinuous and the suspended matter content is high, this project uses the batch-

type plain sedimentation to remove the grains of sand that are easily subsided. It

116


requires to set one settling pond with dimension of 12m×4m×2m; and the pond body

and inlet/outlet uses brick masonry lining. After well treated, the wastewater will be

used for construction road watering or be drained outside; and the waste slag will be

transported to the spoil ground.

B) Treatment of construction machinery and vehicle overhaul washing

wastewater

The main pollutants of construction machinery and vehicle overhaul washing

wastewater are petroleum. Set collecting gutter in the construction machinery

equipping and maintenance area to collect the troubleshooting and washing

wastewater, and set oil separator to treat the oily wastewater. The construction

machinery and vehicle overhaul washing wastewater up to standard after treatment

can be drained to the flood land nearby.

C) Treatment of domestic sewage

The main pollutants in domestic sewage are COD and ammonia nitrogen; there is

not so much domestic sewage and the sewage discharge will not change the water

functional category of Fenquan River surface water and have little impact to the water

quality. But due to domestic sewage water quality exceeds the discharge standards, it

will has adverse impact to residents' health. The evaluation requires the construction

workers to have centralized residence and centralized discharge of domestic sewage.

But after setting septic tank outside the residence of the construction workers, and

send the feces to farm fields for fertilizer after primary treatment on a regular basis.

D) Foundation pit wastewater

The foundation pit drainage shall meet the up-to-standard drainage requirements.

The suspended matter in foundation pit wastewater is generally 2000mg/L, and the

wastewater will be sit for about 2 hours after collected to drainage sump from

drainage open trench; then the suspended matter concentration can be lowered to

150mg/L or less, and what you have to do is to drain it out. The cofferdam built

117


before the underwater construction shall be removed after the completion of the

underwater construction and several days of water settling in the cofferdam.

7.2.3 Water Pollution Impact during Operation Period

The pollution in the operation period is mainly the domestic contamination

caused by the ship lock working personnel and ship working personnel during the

operation period and the oil pollution produced by the ships, and the main pollution

factors are COD, NH3-N and petroleum.

According to the engineering analysis in Chapter III, the output of ship lock

administration office domestic sewage is about 1.3m³/d, which can be only discharged

after it is treated by buried sewage treatment device and reaches the Grade II standard

requirements in Table 4 of Integrated wastewater discharge standard (GB8978-1996).

The domestic sewage discharge value of lockage vessels shall be 1.0m3/d, and the

discharge of vessel domestic sewage shall meet the requirements in Vessel Pollutant

Discharge Standard Requirements. The evaluation region, the primary function of

water body in the Fenquan River section is transportation and irrigation; there is no

integrated drinking water intake and the up to standard discharged domestic sewage

water quantity is small; therefore, it has small influence to Fenquan River water body

environment.

7.2.4 Water Environment Protection Measures in the Operation Period

According to the requirements of navigation administrative department, the

vessels are not allowed to drain bilge oily water to the water body during the lockage

period. Therefore, the normal passing process of lockage vessels has no oil

contamination influence to the water body.

(1) Strengthen the channel management and forbid the garbage along the

channel to enter the channel; release the announcement, forbid to dump the solid

wastes 100m within the bank, and punish the units and residents who dump garbage at

118


will.

(2) Carry out regular salvage and cleaning to the floating objects under the

action of wind.

(3) The Fenquan River channel shall be set with navigation signs based on the

provisions on inland water transportation to make sure shipping safety; strengthen

daily shipping patrol, and completely prevent the risk accidents from polluting the

Fenquan River water quality.

(4) Strengthen the ship management, and the ships shall be equipped with the

appropriate treatment devices or storage containers for the domestic sewage output as

required; any ship cannot discharge the domestic sewage not conforming to the

discharge standard to the inland waters; the ship bilge oily wastewater can only be

discharged after it is treated with the built-in oil-water separator and meets the Vessel

Pollutant Discharge Standard.

(5) Set ship sewage reception facilities in the service area, and for the ship

without oil-water separator or domestic sewage treatment device, the specialized

facilities in the service area can collect the oily sewage and domestic sewage on the

ship to the service area for unified treatment.

(6) the ship lock administration office domestic sewage can be only discharged to

the downstream of ship lock after it is treated by buried sewage treatment devices

("bio-contact oxidation + disinfection" process) and reaches the Grade II standard

requirements in Table 4 of Integrated wastewater discharge standard (GB8978-1996).

7.3 Ecological and Environmental Impact and landscape

Construction

7.3.1 Ecological and Environmental Impact in Construction Period

In construction period, the ecological and environmental impact elements are:

119


(1) Land occupation impact: permanent land occupation is mainly for approach

channel dredging and bridge reconstruction works, including flood land occupation;

and temporary land occupation is mainly for construction machinery, site and mud-

dumping area;

(2) Mechanical work: its rolling compaction damages the aboveground

vegetation and fugitive dusts fall on the leaves of plants, influencing the

photosynthesis and respiration processes.

(3) Water and soil loss: due to dredging of sludge, bridge reconstruction and

other works during the construction process, there might be water and soil loss;

(4) Impact on aquatic organism: it mainly happens in the construction period;

A. Impact on vegetation

The impact of the engineering on the vegetation along is mainly reflected on two

aspects: first, permanent land occupation reduces the vegetation area of the shrubby

grassland and forest land of flood land; second, the temporary land occupation of

mud-dumping area in the construction period will damage the aboveground

vegetation, and its recovery requires a certain period of time. In this section, we focus

on the impact of permanent land occupation to vegetation in the region.

According to field survey and forestry sector advices, the forest occupied in the

project is mainly economic forests, and does not involve ecological and public

welfare forest and rare and protected animals. This project's impact to flood land

mainly is reflected in the flood land shrubby grassland and beach forest land, which

reduces the flood land vegetation area and has a certain influence to the ecological

function and benefits in some areas. This project has little impact to the plant diversity

in this region. After the construction is complete, the landscape construction and

vegetation recovery along the road can gradually make up for the plant diversity and

biomass loss.

120


Meanwhile, with the implementation of slope protection works, the approach

channel afforestation and slope protection engineering can improve the water and soil

loss along the approach channel banks, and also can form an ecological corridor with

clean water and green trees; the artificial ecological system will have obvious regional

ecological benefits and complete the completeness of regional ecology and its

structure and function.

In general, the flood land vegetation loss caused by engineering permanent land

occupation will have certain influence on the existing ecological system; but the loss

amount is next to nothing to the entire region, and the slope protection greening in this

engineering area will make up for considerable biomass; therefore, the vegetation

destroyed by the this engineering will not have influence to the abundance of species

and ecological functions of the ecosystem near the engineering.

B. Impact on terrestrial animals

Impact on terrestrial animals: it mainly happens in the construction period with

following: the land occupation destroys vegetation, and reduces their living area and

food source; the construction noise and light disturbs their normal life; the

construction might pollute the water quality in Fenquan River and regional

atmospheric environment.

The terrestrial wild animals in the project area are the frequent species in the

Huaibei Plain: common birds, beasts and small animals; the wild beasts include

leopard cat, badger, yellow weasel, hare and hedgehog; and the wild birds include

great bustard, white stork, sparrow, turtledove and crow. The influence of this project

on the terrestrial wildlife is mainly during the construction period, when the habitat of

these birds and beasts will be damaged; the construction noise, fugitive dust and

personnel frequent movements will make the wild animals flee because of scare; the

birds lived here will be impacted firstly, and they will temporarily find new habitat

somewhere else. But the project covers small area, and the project area has already

become the artificialized area with lots of human activities instead of the primary

121


habitat, breeding place and wintering ground for protected animals; and most of them

have good moving ability, so they can rapidly migrate to the safe region nearby during

the construction; therefore, the project will have small influence to the terrestrial

animals, and they will get their old life back as soon as the project ends.

C. Impact on aquatic organism

The spatial and temporal distribution and change in quantity of plankton are

closely related to the water transparency, and in the engineering construction period,

bridge pier construction and channel dredging will generate some suspended matters,

which spread with change of water flow field and form a certain range of suspended

matter high-concentration distribution area, leading to the decrease of local water

transparency, and thus influencing the growth of plankton. The suspended sand

increment caused by the construction is not very obvious, and the disturbed bottom

sediment will continuously set and dilute due to the gravity and flow of the river;

therefore, this project's impact to the plankton of Fenquan River is minor.

Benthos is one of the important aquatic organism types in the aquatic ecosystem

of Fenquan River water area, and the impact of environmental change to their survival

is rather obvious due to their low mobility; The species in the river way are all

frequent species, so the impact is temporary; with the completion of the construction,

the bottom sediment is becoming stable, the survival environment of benthos will be

recovered. The area of this project is small compared to Fenquan River waters area;

therefore, the impact of this project to benthos is acceptable.

Due to water quality damage, the reduction of fish baits and other biomass for

plankton and benthos changes the survival, growth and reproduction conditions for

the fishes who will move to other places in another water area; so the fish intensity in

the construction area will significantly drop. But due to the big pollution of Fenquan

River and the fishes in Shaying River are mainly grass carp and other pollutant-

resisting fishes, and there is no valuable or rare/protected varieties of fishes; so the

engineering has little impact to them and the impact is temporary; they can always

122


return to the original habitat after the completion of the construction. In this survey,

there is no wild fish of national priority protection, no fish spawning site, feeding

ground or wintering ground designated by fishery sector; therefore, this project has no

direct influence to spawning and reproduction of fishes.

D. Impact of mud-dumping area

The mud-dumping area in this project is set on the left bank of the Yangqiao

check gate in the low-lying land of downstream side of X017 (Figure 7-2); the mud-

dumping area is a 3-4m low-lying land formed after the soil removal by the local

residents with area of 150 mu, containing the spoil of this project. Due to the mud-

dumping area soil will be covered with the dredged bottom sediment, and the land

will be returned to the local government after the hydraulic reclamation of mud-

dumping area ends. See Figure 7-3 for the current situation of mud-dumping area.

According to our survey, the mud-dumping area has no housing estates within

50m range; so the machinery noise, residual water drainage and stink from bottom

sediment during the construction period of the spoil area might have small influence

to the residents nearby.

7.3.2 Ecological Protection Preventive and Restoring Measures in Construction Period

In order to maintain the ecological balance and protect the biodiversity within the

region, we take ecological protection preventive and restoring measures in the

engineering zone. During the construction period, strengthen the ecological protection

publicity and education to the construction workers and management personnel to

enhance their ecological environment protection consciousness; during the

construction process, avoid wanton felling of trees and try to retain the original

vegetation; the construction workers are not allowed to catch frogs, snakes or birds to

lighten the impact of construction to local terrestrial organism and thus to reduce and

eliminate the impact range and extent to ecological environment. The destroyed

vegetation shall be restored locally or compensated non-locally to reduce the impact

of the engineering to the ecological environment.

Before the construction, carry out topsoil stripping to cultivated land within the

temporary land occupation scope with 0.3m thick of stripping and 1000 m3 of

stripping topsoil, which shall be transported to the temporary soil pile zone for

temporary storage; after the navigation bank filling is done, backfill the topsoil to the

navigation bank surface for the layout of vegetation measures.

The water and soil loss prevention and treatment measures in the temporary

124


excavation area: carry out topsoil stripping before the construction, and transport to

temporary soil pile zone for centralized stacking; set straw-earth cofferdam around the

mud-dumping area and consider the temporary drainage measures; and set obstructs,

drainage and covers around the temporary soil pile zone.

After the spoil ground of the Yangqiao Ship lock extension project is used, use

the topsoil of temporary land occupation for topsoil coverage and try to restore it as

cultivated land and increase the local cultivated land quantity.

7.3.3 Ecological Environmental Impact and Protection Measures in the Operation Period

The Fenquan River channel side afforestation consists of arbors, shrubs and

grasses; grass and shrub grow much faster than the arbors; the area along the channel

requires long-term and professional administration and maintenance; plant the

evergreen herbaceous plants and shrubs that can absorbing dust and noxious gas in the

green belt to beautify the environment and prevent water and soil loss. Therefore, the

channel administration department shall set special department and personnel to run

or entrust botanical garden department to maintain.

7.3.4 Summary

The river system is an important part in the regional ecosystem and plays an

irreplaceable role in the development of creatures and maintenance of ecological

balance. The Fenquan River has multiple times of artificial modification, renovation

and construction in history and a lot of human activities, and the ecological

environment nearby has basically become the compound ecosystem mingled by

artificial ecosystem and natural ecosystem and the artificial ecosystem is dominant;

the completeness of the previous natural ecosystem has been seriously destroyed; in

addition, the area is not the main habitat, breeding place or wintering ground of

protected wild animals.

This project will have certain damage to the ecological environment along the

125


approach channel during the construction period, but this influence is temporary and

its scope is relatively small.; after the project is completed, with the implementation

of water and soil conservation plans, environmental protection measures and slope

protection greening works, ecological benefit after the artificial ecosystem will

significantly act; the region's ecological integrity and its structure and function will

improve instead of weaken.

7.4 Evaluation of Impact on Environmental Air

7.4.1 Prediction of Impact on Environmental Air in Construction Period

During the construction period, fugitive dust will have the biggest influence to

the environmental air, and the influence of fuel waste gas from the transportation and

equipment operation and the stinks in the mud-dumping area ranks second. The

construction dust raising includes the directly discharged dust in the construction

process, and the secondary dust raising of surface regolith due to wind or other power

conditions. The dust raising in this project mainly comes from foundation pit

excavation, stock yard exploitation, waste slag stacking and vehicle transportation,

and the main pollutant is TSP.

1. Impact of fugitive dust on environmental air

The main impact of fugitive dust in construction on atmospheric environment is

to increase the suspended particulate matter concentration in the air. Fugitive dust has

3 aspects: fugitive dust out of construction, from vehicle pass-by and produced by

wind force for the loose soil on the site and roads. After the construction of this

project is done, the impact to atmospheric environment will disappear itself.

The total earthwork excavated in this project is 760,600 m³, and the influence

scope can be as far as 50m based on the dust raising volume, wind force, humidity of

the materials and civilization degree of the construction; however, it will not have

very big adverse influence to Yangqiao town and other environmental air sensitive

126


spots.

Fugitive dust during the transportation mainly comes from two aspects: one is

the dust produced by vehicles, and the second is the transportation of dusty materials

such as cement; when the vehicles are not properly blocked during moving, the

materials may be losing and floating, which increases the dust content in the air on the

sides of the highway. Compare to the empirical data of fugitive dust from motor

vehicles, and if the construction road traffic flow is 35 /h and the vehicle load is

15~20t, then dust discharging strength of the concrete pavement is 67.2mg/s·m, and

that of the macadam pavement and rural highway is 74mg/s·m.

The construction roads of this project are mostly macadam pavement and the

dust raised by the transportation vehicles especially in dry seasons is the main

problem of fugitive dust in construction. The fugitive dust from vehicles is the main

source of dust in construction. It is not averagely distributed in a large range, but have

big concentration in certain small spaces. On the road section with a lot of

accumulated dust, there will be dense fugitive dust when load-carrying vehicles pass

by, with general width of 10~50m and height of 4~5m.3 minutes later, the bigger

particles will settle to the ground, and the fine particles will stay a little bit longer in

the air.

The engineering construction will raise dust to the project area and the

construction roads, which will have a certain impact to the construction workers and

residents nearby exposed to the dust for a long time. Therefore, the construction

organization must take dust suppression measures, including watering the

construction site, strengthening of the management measures and labor protection to

the on-site construction workers. These measures will reduce the fugitive dust volume

by 50%~70%, and can effectively reduce the impact of dust raising on environmental

air. The engineering dust raising's pollution to the environmental air is temporary and

local and will be gone after the completion of construction.

2. Impact of vehicle tail gas on environmental air

127


Due to the pollutant volume discharged from fuels out of transportation and

construction equipment operation, and these pollutants are discharged in a flowing

and spreading manner; the construction area atmospheric pollutant spreading and

dilution conditions in the contamination area are good, which will not have adverse

influence to the atmospheric environmental quality and function.

7.4.2 Atmospheric Environment Protection Measures in the Construction Period

In the construction process of this project, the primary impacts to environmental

air include stink from the bottom sediment dredging and fugitive dust in the

construction process.

(1) Stink pollution control measures

A. During design, the selection of mud-dumping area shall avoid villages, and

from the aspect of site survey, the mud-dumping area is 50m or more away from

villages, which effectively avoids the influence of sediment odor stink to the residents

nearby;

B. The dredging of approach channel shall be carried out in the low water

season, ideally winter; the smell of bottom sediment will does not easily diffuse, and

it can reduce the influence of stink to residents nearby. At the same time, carry out

section construction, timely transport the dredged bottom sediment to the mud-

dumping area, and timely carry out ecological recovery treatment;

(2) Dust pollution control measures

a. There shall be the enclosure not lower than 1.8m in the construction site, and

water the land area at any time to reduce the pollution of fugitive dust and set muck

collecting enclosure in water area, and make sure that the muck will be moved away

within three days after the construction.

b. The transportation of earthwork, muck and construction garbage must use

closed vehicles and set the facility to wash vehicles at the entrance of the construction

128


site to wash the vehicles when leaving the site and not bring mud and sand out of the

site.

c. Take effective measures in the construction site, including covering,

solidification, greening and watering. The fugitive dust on the roads and in the

construction site shall be dealt with watering and cleaning mechanism, and it is

required to equip one watering cart in the construction site.

d. Cement and other easily fly-upward fine grain building materials shall be

stored in an enclosed manner, and the lime and sand in the construction site shall be

collectively stacked and covered.

e. The lime and inorganic materials shall be pre-mixed before mobilization, and

the machine shed with agitator in the construction site must be enclosed and equipped

with effect dust-fall and anti-=dust devices.

f. If there is force 4 wind or above, it is not allowed to carry out earthwork

backfill, transportation and other construction works might have the pollution of

fugitive dust.

g. The vegetation of temporarily occupied land shall be recovered to prevent

water and soil loss.

(3) Miscellaneous

Try to select the vehicles with low energy consumption and low pollution

emission, and the constructor shall install tail gas clean-up devices for the vehicles

with exhaust emission out of limits. Strengthen the management and maintenance to

machinery and vehicles and reduce the air pollution caused by poor states of

machinery and vehicles.

7.4.3 Impact on Environmental Air in Operation Period

In operation period, the exhaust gas pollutants are mainly from the fuel oil

129


exhaust gas, including SO2, CO, NO2, in the way of linear emission along the shipping

lane; there are good air diffusion conditions in the region, so the air environment

quality will not degenerate. The air environment quality in the to-be construction site

shall meet the requirements for Class 2 area in Environmental air quality standard

(GB3095-1996).

7.5 Acoustic Environmental Impact Evaluation

7.5.1 Acoustic Environment in Construction Period

According to characteristics, size, site layout and construction mechanical

equipment selection of the project, the noises generated in the construction activities

of this project mainly include construction material processing and construction

machinery noises, and the explosion noise of old ship lock removal. According to the

engineering field monitoring in similar engineering, and see Table 7-1 for

construction machinery noise; the sound level of primary construction machinery high

noise sound level equipment is 80~100dB (A).

According to Environmental Impact Assessment Specifications for Inland

Waterway Project (JTJ227-2001), this project uses the calculation formula for point

acoustic source at semi free space attenuation to calculate the sound attenuation

situations of the construction machineries, and calculate the noise values of different

distances from an acoustic source by lapping the noises and the background values.

LA(r)=LA(r0)-20lg(r/r0）-ΔLA

Where: LA(r) ······ A sound level r away from the acoustic source, dB (A);

LA (r0) ······ A sound level of reference position r0, dB (A);

ΔLA····· A sound level attenuation caused by other elements; due to the

openness of the project area, this evaluation does not calculate the attenuation values;

take 0dB (A);

2. Impact prediction of noise contribution value (Day)

According to the site layout and construction arrangement, taking the

unfavorable situation into consideration, select the excavator, bulldozer, motor lorry

and other construction machineries with greater noise, and concrete mixing station

and steel & wood processing factory as noise source. See Table 7-2 and 7-3 for the

prediction of the noise contribution values of different distances from the acoustic

sources.

According to 4a standard in Environmental quality standards for noise (GB3096-

2008) (70dB in day time and 55dB in night time), and the earthwork construction and

structure construction noise limit in Emission Standard of Environment Noise for

Boundary of Construction Site (GB12523-2011) (70dB in day time and 55dB in night

time); the concrete mixing station can be up to standard 10m away in day time and

basically 35m away in night time; the steel & wood processing factory acoustic

source grade reaches 100dB (A), which is up to standard 70m away in day time, and

350m away in night. The excavator, bulldozer and motor lorry have limited noise

influence scopes respectively, but when the three of them are superimposed, they have

great influence to the acoustic environment. Due to the uncertainty of the combination

of the equipment, this evaluation cannot have quantitative evaluation. Based on the

location of this project, the environment evaluation suggests that the construction in

night time is not allowed. Due to the engineering requires night-time construction, the

building undertakers must file an application to Liquan Environmental Protection

Bureau and inform the residents nearby by posting a notice and let them take

precautionary measures. The evaluation requires the constructor to strengthen

environmental management and supervises and urges the constructor to strengthen

equipment management and control construction time according to Emission Standard

of Environment Noise for Boundary of Construction Site (GB12523-2011).

The ship lock and highway bridge reconstruction and wiring works will have a

132


certain influence to the residents in this area. The construction area in this project is

located in the south of Wanggao Village, and the concrete mixing station and the steel

& wood processing factory are located within the ship lock administration office.

According to site survey, the acoustic environment sensitive spot near the project area

is mainly Wanggao Village. Due to the noise source intensity in the steel & wood

processing factory is high, in the project construction organization design, the steel &

wood processing factory shall be set in a temporary house for noise reduction; the

lowest noise reduction of temporary house is 15dB (A), and the concrete mixing

station fully meets the requirements; thus the steel & wood processing factory can be

fully up to standard in day time and at 100m in night time. Therefore, the steel &

wood processing factory is not allowed to operate during the construction period to

avoid influence to the residents in Wanggao Village in night time.

The ship lock engineering and highway bridge and wiring construction might

have some influence to the ambient environment sensitive spots and occasionally

make the acoustic environment out of limits. But these noise sources are temporary in

construction period, and only have impact to local environment in a short term, and

these impacts will be gone after the completion of construction.

7.5.2 Acoustic Environment Protection Measures in Construction Period

During the construction period, the service time of equipment making noises

shall be strictly managed and controlled, and high noise equipment shall not be

allowed to use in nigh time; at the same time, you shall select the locations and

directions to place the equipment, pay attention to use natural conditions and

buildings (structures) to reduce noises, and make the impact of noises in the

construction period to the minimum.

(1) First, use low noise equipment as far as possible, for example, use hydraulic

machinery instead of fuel machinery, and use high-frequency vibrorammer; for the

fastening mechanical equipment, excavation and earth moving machinery, such as

133


excavator and bulldozer, you can reduce the noise by exhaust pipe silencer and

isolation of motor vibration parts.

The mechanical equipment will have increased sound level due to loose parts

vibration or damage of silencer, so the construction organization shall have regular

maintenance and service to the mechanical equipment.

Immediately close the unused equipment, and the transport vehicles shall slow

down when they are getting into the site and try not to honk their horns.

(2) Draw up scientific construction plan and reasonably arrange the construction

time, and try to avoid using many high-noise equipment together; in addition, the

construction time of high-noise equipment (such as excavator and agitator) shall be

arranged in day time instead of night time (22:00~06:00).

During nights, the construction organization shall reduce the transportation of in-

situ concrete and large-scale materials, and if the continuous work is required due to

the bridge reconstruction, the construction organization shall try to take noise

reduction measures, notify the residents nearby about the construction time and

location, and report to the environmental protection agency for registration before the

construction.

(3) The construction organization shall set mobile acoustic barrier to the noise

sensitive spots to reduce the impact of construction noise.

(4) Operate the mechanical equipment as specified and abide by the operating

rules during the process of baffle and bracket disassembly; reduce the collision noise

in loading and unloading the materials.

(5) Avoid to arrange too many mechanical equipment at a same location to

prevent too high local sound level; try to use modern communication equipment

instead of whistles, clocks or flute to direct the construction.

(6) The electric saw, electric planer, agitator, fixed concrete delivery pump, large-

134


scale air compressor and other high-noise equipment shall be set in the side away

from the residential area to reduce noise pollution.

(7) The building organization shall pacify the residents nearby together with the

construction organization, announce their construction timescale, and establish good

community relationship with the companies and residents along the routes. In order to

seek the common understanding, the construction organization shall notify the entities

and individuals disturbed by the construction, and tell them the construction progress

and measures taken to lower the noise. In addition, they shall set complaint hotline

during the construction period for the complaints about noises from the residents, and

actively handle the complaints.

7.5.3 Noise Impact and Control Measures in Operation Period

The ships generate small noises during navigation, which are flowing acoustic

source. The power-driven vessels use diesel engine, so the engine noise during the

operation period (including gas discharge sound) is the primary acoustic source in

approach channel operation period. Other noise sources also include on-site work

commanding speakers and ship whistles, which can be effectively controlled via

strengthened management.

According to Environmental Impact Assessment Specifications for Inland

Waterway Project (JTJ227-2001), the ship navigation noise radiation sound level shall

be calculated based on:

(Lp) i= (Lw) i+10lg (Ni/ViT) +10lg (D0/D) 1+α-13-ΔLA

Where: (Lp) i·····the radiation sound level of i type ship per hour at location D,

dB (A);

(Lw) i······ the average radiation sound level of i type ship, dB (A);

Ni····the average flow of i type ship in day time or night time, ship/h; (see Table 3-5)

135


Vi······ the average speed of i type ship, km/h; (calculated by 10km/h)

T······· predicted time, take 1h;

D0······predicted reference distance of ship radiation sound level, take 15m;

ΔLA····· A sound level attenuation caused by side wall and other elements, take 10dB (A);

A······· ground parameter, take 0.3;

For the (Lw)i value of ship, consider that most of the ships in the approach

channel and gate are power- driven ships, use diesel engine as power, and the speeds

of lockage ships are rather low (take 10km/h here). So the engine noise during the

operation period (including gas discharge sound) is the primary acoustic source in

approach channel operation period. This evaluation looks into related materials, and

see Table 6-4 for the noise source intensity of ships of different powers.

From Table 6-5, we can know that when the cabin door is open, the ship noise

during the operation period basically has no influence to the acoustic environment

spot (Wanggao Village) and it meets the Grade 2 standard requirements in

Environmental quality standards for noise (GB3096-2008). When the ships are

navigating, the cabin door is usually closed, and the noise source can reduce by 6dB

(A) or more; therefore, ship navigation has no impact to the surrounding environment

sensitive spot. In addition, the ship engine shall be equipped with effective silencer

and ensured to be functional, and the discharged noise shall conform to state-level

Inland River Ship Noise Sound Level Provisions.

The noise sources also include on-site work commanding speakers and ship

whistles. According to related regulations, the equivalent acoustic value of the ship

whistling is as high as 85dB 200m away. The ship whistling noise and on-site work

commanding speaker noise have the characteristics of intermittence and emergency,

and has more influence over the sensitive spots. For such noise, many measures shall

be taken to reduce the influence to surrounding environment as far as possible.

7.5.4 Acoustic Environment Protection Measures in the Operation Period

We advise the building organization and the port administrative department to

strengthen management and close the ship cabin during lockage and navigation to

eliminate the impact of ship noises to ambient environment.

137


When the ships are passing the ship lock, the building organization shall use

sound devices as specified in ship safe navigation provisions without honking the

whistles at will. The work-commanding speakers shall be controlled with their

volume and not allowed to use at night.

7.6 Analysis on Solid Waste Pollution

7.6.1 Solid Wastes and Control Measures during the Construction Period

The solid wastes during the construction period are mainly from the excavation

spoil, construction ship garbage, construction garbage and household garbage of the

construction workers.

Measures: 1) the spoil and construction garbage produced in this project shall not

be dumped to ditches at will, and they shall be used for leveling the base of rural

residence based on new rural and town construction policies.2) The underwater

earthwork mud-dumping area shall be used for greening or construction of protection

forest after natural drying.3) Set 2 trash cans in the construction camps and arrange

specially-assigned persons to clean and transport the household garbage. The trash

cans need to be sprayed with miehailin aerosol and other liquid to prevent and treat

the breed of flies and other infectious vectors. The household garbage shall be

collected and transported by the local sanitation department to the garbage disposal

plant in a timely manner.4) After the completion of this engineering, remove the

temporary facilities in the construction area, timely clean the concrete mixing system,

construction machinery parking lot, dimension stone charge make-up area,

comprehensive warehouse and office/living quarter, get rid of construction garbage

and sundries, clean and level the household garbage, outdoor toilets and sewage pit,

use quick lime to disinfect and do the construction slash recovery right.

7.6.2 Solid Wastes and Control Measures during the Operation Period

The solid wastes in the operation period are mostly the household garbage

138


generated by the ship lock management personnel and workers on the ships.

Calculated by 1.0kg/person · day for the output of household garbage, the 13 new

working personnel on the ship lock will produce 4290kg/a garbage. The household

garbage in the operation period shall be handed over to the local sanitation department

for transportation and treatment after the collection.

For the household garbage generated by the ship workers, according to the

Provisions of the People's Republic of China on the Prevention and Control of Vessel

Pollution of the Inland Water Environment, "it is not allowed to discharge ship

garbage to the inland waters and the ship garbage must be treated by the department

with qualifications", the ships shall be equipped with waste storage containers that

have lid, do not leak or spill, or bag the garbage; classify, collect and keep the garbage

to meet the need of storing ship garbage during the navigation.

7.7 Accident Risk Pollution Analysis

Upon completion of the project, quantity of vessels passing Yaoqiao Dam Lock

will be increased effectively, and the transit capacity of Fenquan River will be

improved. While sometimes emergencies such as ship collision or ship sinking may

occur due to unforeseen reasons. As per forecast on cargo volume during the

operation period and relevant statistics, vessels travel on the river only carry coal,

building material and chemical materials, etc. The sinking of coal and building

material, etc. will have limited effect on the water quality of the waterbody, while the

sinking of chemicals will have greater impact on water quality, so, the EIA mainly

analyzes risks aroused from chemical materials. Clause 14 of Regulations on Anhui

Province Water Traffic Safety Management, implemented on March 1st, 2014

stipulates that “Inland rivers and lakes are prohibited to be used for the transportation

of highly toxic chemicals and other hazardous chemicals that Chinese government

prohibits to transport through inland rivers”.

As per investigation, main chemical materials transported on the waterway are

139


methanol, hydrogen peroxide, urea and synthetic ammonia, etc. produced by Linhua

Group. These goods are mainly transported first by trucks to the Hongchao port at

Yangqiao Dam Lock, and then transported via the waterway. Hoongchao port is a

special port of Linhua Group for methanol and hydrogen peroxide, with transportation

pipelines and storage tanks for liquid hazardous chemicals being built at the port. To

make Hongchao port a safe port, in 2014, RMB138, 000Yuan was invested by the

group for the safety standardization works of the port, including modification to the

operation sites and upgrading of the site monitoring and control hardware facilities. In

addition, to strengthen the integrated safety management flow, a safety production

management organization, with the legal person of Hongchao Port Co., Ltd. as the

main leader, was established. Besides, a series of port safety management regulations

including PortSafety Production Operation Regulation, Site Patrol Inspection

Regulation, Personnel Safety Training Regulation and various emergency response

plans have been prepared as required, and are kept on revising and updating. Thus,

staff can be constrained and managed by these regulations. The safety responsibility

supervision and assessment mechanism was established for the supervision of the

implementation of safety responsibilities, which assures the safety production of the

port.

Fuyang Local Marine Bureau performs periodic inspection to assure the

production safety. Before any operation, port administration officers and site marine

officers will jointly have an overall safety inspection to hazardous chemicals carrying

vessels, examine operation qualifications of hazardous chemicals transportation

vessels, so as to prevent all people without correct qualifications from operation

works and all vessels without correct qualifications from carrying hazardous goods,

which assures all vessels are qualified for transportation and loading. The inspection

on the safety of various links of vehicle transportation and vessel transportation are

strengthened, and vehicle guards and site safety inspector shall own relevant safety

qualifications. Through the more strict safety inspection on various links for

hazardous goods storage and transportation, potential safety risks are eliminated in the

140


embryonic stage. By a series of pertinent measures, the width and depth of safety

production are guaranteed. Besides, Fuyang Local Marine Bureau has improved its

emergency response ability through performing exercises on disposal of hazardous

chemical leakage, etc.

As per Analysis on Fuyang City Waterway Traffic Safety Situation by Fuyang

Local Marine Bureau, in 2012 and 2013, no collision or leakage accidents occur to

hazardous chemical carrying ships.

Probabilities of accidents like collision of hazardous chemical carrying ship, etc.

in the waterway is very small, but there does exist the possibility. Once the small

probability event occurs, it will have such very serious devastating impact to the water

as killing fish in the river, poisoning organic life and threatening safety of downstream

water intake, etc. So, in case of any chemical material relating accident, its effect will

be great.

7.7.1 Influence over Aquatic Ecology and Fishery Resources

In case of chemical leak due to ship collision, the influence on the aquatic

ecology of the Fenquan River will be multi-dimensional.

Fish feed is the foundation of all fishery waters and the precondition for the

survival of all aquatic lives in the drainage basin of the Fenquan River. Plankton with

poor mobility will be the first to be affected, chemical substances are toxic and

harmful for them; plankton is the producer in the aquatic life community, and the

biological basis for the feed in the waters, so chemical substances will influence other

creatures as feed through the plankton.

Besides, chemical substances are highly toxic to young fish and larva fish, in

particular, the floating fish eggs. Fish eggs and larva fishes may be poisoned by high

concentration chemical substances soon; the feeding and breeding of fish may be

disturbed exposure to long-term low-concentration sub-acute toxicity; and the toxicity

will vary as the constituents of chemical substances differ.

141


7.7.2 Precautions Against Risks

(1) Safety and pollution prevention measures shall be taken for the ships carrying

flammable, explosive, corrosive, hazardous or radioactive goods. Specified signs shall

be displayed, the provisions in the Regulations Governing the Supervision and

Control of Vessels Carrying Dangerous Goods specified by the Ministry of Transport.

(2) The ships must have the ship certificates of inspection issued by marine

administration department, certificate of registry, crew conforming to provisions of

the transportation department of State Council, and necessary navigations materials.

According to national provisions, the scrapped ships cannot be used for navigation or

operation.

The transportation ships must conform to the safety technical requirements and

other conditions required by the transportation department of State Council, including

ship strength, stability, draught, firefighting and lifesaving.

The crew shall have professional training about marine traffic safety, and the

crew shipping dangerous cargoes shall have related special trainings, pass the exams

of marine administration organization and only become a mariner after getting related

certificates of competency. Any crew without certificates of competency or other

licenses is not allowed to get on board.

(3) Emergency facilities for accidental spill

At present, large rescue and salvage ships and devices have been provided in the

emergency system of Fuyang Maritime Safety Administration. For accident handling

and rescue on the channel, the maritime authority will play a major role. The project

company shall cooperate with Fuyang Maritime Safety Administration in the

equipment system, formulate a cooperation plan to facilitate allocation of emergency

teams and devices.

For the accident occurring on the channel, the project company shall provide

142


necessary emergency rescue devices and instruments at the ship lock administration

office to facilitate emergency help. They mainly include emergency vehicles for

protection and handling, antidotes, solid and liquid substance cleaning and recovering

devices, rubber plugs and sandbags; the emergency devices to be provided for this

project are listed in Table 7-1.

(4) To ensure that help can be received in case of emergency in the water area,

Fuyang local marine bureau and the ship lock administration office shall set an

emergency office and assign someone to be in charge. Meanwhile, set the patrol

boat; once emergency occurs in the water area, it shall timely report local

government, the Maritime Safety Administration and the EPA of Fuyang, actively

organize emergency actions, timely salvage and rescue sunk articles, to ensure the

waters environment is safe and the channel is unobstructed.

(5) The chemical materials transported by this channel are mainly methanol,

urea and synthesis ammonia. Investigation finds that all of such raw materials are

held in sealed containers; after shipwreck, leak is unlikely to occur, but timely

143


salvaging is required to prevent them from being flushed away. In case of leak, an

accident affected zone is divided, the neighboring inhabitants are informed that the

water in the Fenquan River may not be used; after the accident is dealt with, the

inhabitants will be notified again.

7.7.3. Environment Risk Emergency Plan

To address unexpected pollution incidents, strengthen emergency handling and

minimize the hazard of pollution, according to the Environmental Protection Law of

the People's Republic of China, the Regulations of the People's Republic of China on

the Administration of Traffic Safety in Inland Waters, Overall Emergency Plan for

State Public Emergency (2006.1.8) by the State Council, the Measures for the

Information Report of Environmental Emergencies (For Trial Implementation) by

the State Environmental Protection Administration, the Provisions of the People's

Republic of China on the Prevention and Control of Vessel Pollution of the Inland

Water Environment by the Ministry of Communications, a contingency plan against

dangerous chemical accidents shall be formulated. This project shall be incorporated

into the local emergency plan for the public accident and the emergency plan for the

public accident department. Carry out emergency deployment according to the

emergency requirements and provisions to cargo ship by PRC marine bureau,

establish corresponding emergency mechanism, including emergency command

center, first-aid rescue team, emergency reserve team and emergency maintenance

team. See Figure 7-6 for the facilities and workflow.

7.8 Analysis of indirect effects and cumulative effects

With the implementation of this project, the Fenquan River channel will have a

rapid-development period; it will have inductive effect to the cargo ships in Fenquan

River, and a lot of cargo ships will be put into use due to the opening of Yangqiao ship

lock, which will bring new environmental pressure to this region and thus have

cumulative impact to the water quality of Fenquan River and environment along the

channel. The current channel of Quan River bends somewhere with the minimum

bending radius of around 100m, which imposes a certain impact on sailing boats and

ships. In addition, the initial stage of the Quan River channel improvement project is

under implementation, and it is believed that the further implementation of the Quan

River channel improvement project will impose cumulative impact on the

environment of Fenquan River and its beaches.

In view of the new ship lock engineering, its influence to the region along the

channel of Fenquan River is small; but with the full openness to ships, the huge

increase of cargo ships will have impact to the environment of Fenquan River, and the

impact might have cumulative act to the regional environment from the angles of

space and time.

7.8.1 Scope Definition

The cumulative impact comes from the crowding effect of environmental

disturbance at space (geography) and time. If the ecological system has not fully

recovered from the influence caused by first disturbance and gets the second

disturbance at the same location, then the effect caused by human activities will be

accumulated.

(1) Cumulative impact identification

According to the "To Consider Cumulative Impacts under National environment"

report issued by Council of Environmental Quality (CEQ) in 1997, there are eight

types of cumulative impacts, as shown in Table 7-13.

146

The effects of Yangqiao lock expansion project on environment is short, partial

and recoverable, so such effects of this project on local environment focus on the

operation period. After the lock is completed, the ship type sailed in the channel will

become larger, the number of ships will increase and the quantity of cargoes crossing

the lock will rise sharply due to the inductive effect of freight ships in Fenquan River.

The current channel of Quan River bends somewhere with the minimum bending

radius of around 100m, which imposes a certain impact on economic efficiency of

147


Yangqiao lock. In addition, the initial stage of the Quan River channel improvement

project is under implementation, and it is believed that Yangqiao lock construction can

further promote the implementation of the Quan River channel improvement project.

Therefore, the cumulative environmental effects caused by this project, channels and

port areas include as follows:

①The cumulative impacts to ecological environment: impact to the wild animals (especially ) in

this area; meanwhile, the ship lock may have blocking effect to Fenquan River, which might

influence the aquatic ecology and fish breeding migration;The potential hazards to the ecological

environment of the channel due to shipping dangerous chemicals.

②The cumulative impacts to atmospheric environment: the fuel waste gas discharged

by the ships in the channel and the vehicle transportation on the wharf might cause the

NOx accumulation in the local atmospheric environment; Vehicle exhaust, road dust,

dust of mineral construction materials and coal dust resulting from port roads, yards,

etc.

Cumulative effects on the water environment: the cumulative effects on the water environment③

of Fenquan River resulting from domestic waste water produced by crew, terrestrial domestic

waste water produced by the port area, rain and sewage drainage regarding yards, etc.

④The cumulative impacts to social environment: with the implementation of this

project and increase of shipment quantity, it will have great boosting to the regional

economy.

(2) Evaluation of space scope and time scope

See Table 7-14 for the space scope and time scope of cumulative impact analysis

in this evaluation.

With the development of scientific and technological level and the promotion of

high technology, the future inland river ships and vehicles will be environmental

protected and energy-saving, and the discharged air pollutants will be smaller and

smaller; and with the openness to navigation in the Fenquan River channel, the

urbanization along the channel will be greatly accelerated; by the planned late phase,

the service area and ports along the Fenquan River channel will have already had the

conditions and the sewage can be discharged to the municipal pipe network for

unified management. Therefore, this evaluation focuses on the 5-year cumulative

environmental impact from the completion of the ship lock (about in 2015) to the

planned middle phase (in 2020).

7.8.2 Cumulative Environmental Impact Analysis

(1) Cumulative impact analysis of ecological environment

1) Impact on beach wetland

According to field survey and department visits, Fenquan River has experienced

multiple times of artificial make-over, renovation and construction in the past and

there were frequent human activities; the ecological environment along the channel is

mainly artificial ecosystem, and the terrestrial animals in the area are mainly common

species and ordinary species; from the angle of living species, this project will not

cause the reduction of population quantity of plants and terrestrial animals. The

engineering operation will not have obvious cumulative impacts to beach wetland

vegetation and wild animal habitat along the channel.

2) Impact on aquatic organism

149


Generally, for breeding migrated fishes or the fishes with very large activity

space, the ship lock construction might block their breeding migration or living space;

but the blocking effect during the operation of the ship lock is temporary, and fishes

will smoothly pass the ship lock by regular lock opening and water discharge;

therefore, the ship lock's blocking influence to fish breeding migration or activities is

very small.

Thus, Yangqiao ship lock has small blocking influence to the fish breeding

migration or activities.

3 ） See Clause 7.7 for the analysis on ecological environment impact of

hazardous chemical substance ship.

(2) Cumulative impact analysis of atmospheric environment

The cumulative impacts to atmospheric environment: the fuel waste gas

discharged by the ships in the channel and the vehicle transportation on the ports and

wharf along the channel might cause the NOx accumulation in the local atmospheric

environment. After the project starts to operation, some cargoes previously

transported to the Linquan County by land way will be transported by waterway. After

the land way transportation becomes waterway transportation, the pollutant volume

and cost to transport each ton of cargoes will be significantly fall. In addition, the

perennial prevailing wind direction in Linquan county is east wind and the mean

annual wind speed is 2.8m/s; the surrounding terrain is flat, the diluting capacity of air

is strong, and the pollution source is mobile; both channel and wharf are located in

rural area, far away from population centers. Therefore, the completion of this project

will not lead to the NOx accumulation in the atmospheric environment in this area,

which has small influence to the air environment in this region. Meanwhile, with the

development of scientific and technological level and the promotion of high

technology, the future inland river ships and vehicles will be environmental protected

and energy-saving, and the discharged air pollutants will be smaller and smaller.

(3) Cumulative impact analysis of water environment

150


The cumulative impacts of this project to Fenquan River environment are mainly

the sewage discharge in channel service area and wharf. The sewage discharge after

the operation of this project mainly includes land sewage and ship sewage. Because

the ships shall be equipped with the appropriate treatment devices or storage

containers for the domestic sewage output as required, which will collect the oily

sewage and domestic sewage on the ship to the service area or port are for unified

treatment without discharging to Fenquan River. Therefore, the ship lock operation's

cumulative impact to Fenquan River water environment is acceptable.

(4) Cumulative impact analysis of social environment

With the construction and operation of the ship lock, cargo transportation will

reduce the dependence to highway, which will reduce the impact to residents along

the highway due to large amount of cargo highway transportation. The overall

navigation of Fenquan River will thus promote the economic construction and

development in Fenquan County and the surrounding area, increase the employment

rate of the area and the economic development in this area.

7.8.3 Cumulative Environmental Impact Conclusion

Based on the analysis above, the construction and operation of this project will

not have obvious cumulative impact to the regional ecological environment,

atmospheric environment and water environment. Meanwhile, the build-up and

operation of this project will promote the economic development of Linquan County.

Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 8. Water and Soil Conservation

8 Water and Soil Conservation

8.1 Water and Soil Loss Current Situation in the Project Area

8.1.1 Zones to Control Water and Soil Losses

According to the water and soil conservation function division specified in

Notice on Division of State-Level Water and Soil Loss Key Prevention and Treatment

Areas and People's Government of Anhui Province's Notice on Division of State-Level

Water and Soil Loss Key Prevention and Treatment Areas and Strengthening of Water

and Soil Conservation Work, this area does not belong to state-level or province-level

water and soil loss key prevention and protection area, key treatment area or key

supervision area; so the area is not the key prevention and treatment area for water

and soil loss.

8.1.2 Water and Soil Loss Current Situation

According to the data released by the national spatial data publishing system of

soil and water conservation in the Water and Soil Conservation Monitoring Center of

Ministry of Water Resources and the Anhui Water and Soil Conservation Monitoring

Bulletin issued by Water Resources Department of Anhui Province in December,

2005, Linquan county, the project area, is the area of no obvious erosion.

According to Standards for classification and gradation of soil erosion, this

project area belongs to earth-rock mountain region in North China, and its soil erosion

is mainly water erosion; the pattern of manifestation is mainly surface erosion, then

liner erosion; the admissible value for water and soil loss is 200t/k ㎡ ·a. The

compiling organization carried out an investigation to the water and soil loss

background value of the project area, the project area is covered by a large amount of

152


crops and a few arbors; the erosion is not very strong, and the soil erosion module is

about 200t/k㎡·a. Via the field investigation and local department, we think the soil

erosion module is basically consistent.

8.2 Water and Soil Loss Factor Analysis

The water and soil loss current situation in the project area is mainly water

erosion because of natural factor and anthropogenic factor. Natural factors are the

precondition for the occurrence of water and soil loss, and the anthropogenic factors

play a dominant role in the occurrence and development of water and soil loss.

8.2.1 Natural Factors

The natural factors influencing water and soil loss during the project area include

precipitation, soil, vegetation and landform. The topsoil stripping, excavation, filling

and spoil works in the construction area will destroy the original landform and

vegetation of the topsoil; are surface, loose structure, weakening topsoil anti-erosion

ability, raindrop hit and runoff flushing, all of these will lead to water and soil loss.

The normal mean amount of precipitation in the project area is 895.0mm, the

precipitation amount in flood season (from June to September) takes account 60% or

more of annual amount of precipitation; during the flood season, the precipitation is

centralized, intensified and has great erosion to soil. During rainy season, the topsoil

is in the moist state, its anti-erosion ability is poor, and severe soil erosion will happen

if any rainstorm.

The soil in the project area is mainly gravel soil, and the land here is basically

cultivated land with large coverage of crops; it is not good for the control of water and

soil loss. The above four aspects, landform, precipitation, ground substance

composition and vegetation, constitute the natural factors of water and soil loss.

153


8.2.2 Anthropogenic Factors

The construction activities will temporarily throw aside a lot of spoil and

offscum, and once they are flushed by rainstorm and surface runoff, the loose and

bare soil will have intense erosion even the terrain is flat.

This project includes removal of old ship lock, excavation of approach channel,

ground leveling, foundation pit excavation of buildings, layout pf temporarily built

facilities, road construction and layout of spoil area. The earthwork excavation and

filling workload is big and it is disperse; if no related water and soil conservation

measure is taken, it will cause water and soil loss very easily, destroy the local

ecological environment, influence the productivity of the surrounding farmland, and

might endanger the surrounding channel safety.

See Table 8-1 for water and soil loss factor analysis in the project area.

8.3 Water and Soil Loss Features

1. During the construction preparation period, the main activities include old ship

lock removal, removal of attachments or transplantation of the planted arbors and

shrubs on approach channel side slope, construction production/living area and spoil

area. Due to the original land is disturbed, the covering stuffs (buildings and

vegetation) are removed, a large area of land will be completely exposed, which is

easily leading to water and soil loss.

2. During the civil engineering construction period, there are approach channel

excavation expanding, a lot of structure building engineering and side slope works;

therefore, a lot of original landforms are disturbed, and there are space and time

differences between the excavation and filling; the bare soil or spoil are easily leading

to new water and soil loss.

3. During the natural restoration period, the excavation and filling disturbance to

topsoil are all done, and the zones respectively carry out protection measures; the

forest and grass vegetation has been restored and begins to be useful; the water and

soil loss can be significantly reduced.

4. After the project is completed, most of the grounds of works organizations will

have been occupied or used by the buildings; the bare soil will be carried out with

prevention and treatment by engineering measures and plant measures and there is

also greening on the empty ground in this area; the spoil area vegetation will be

basically restored, and there will be no spoil during the operation period or any new

water and soil loss.

155


8.4 Water and Soil Loss Prediction Scope and Time Frame

According to the construction features of this project and its water and soil loss

prevention and treatment responsible scope, the prediction scope of water and soil

loss is channel engineering area, embankment engineering area, highway bridge and

wiring area, ship lock administration area, construction production/living area, and

spoil area (including temporary soil pile zone). The water and soil loss volumes are

predicted respectively based on construction preparation period, civil engineering

construction period and natural recovery period. According to the schedule of the

single projects, see Table 8-2 for the water and soil loss partition prediction time

frames in construction period and natural restoration period

8.5 Water and Soil Loss Prediction

8.5.1 Soil Erosion Module Determination

1. Native landscape soil erosion module

Based on field investigation, the module can be determined by the landform, soil

type, local precipitation, vegetation coverage, ground substance composition and

management measures in the construction area. This project area is light erosion area

and the native landscape soil erosion module in the project area is 200t/k㎡·a.

157


2. Soil erosion module after the disturbance

The erosion module after the disturbance shall be analyzed with analogy method

and determined after comparing with other projects; the comparing project for this

project is Linhuaigang project.

1) Analogy condition analysis

8.6 Water and Soil Loss Hazard Prediction

According to the above water and soil loss prediction results, combine the

landform and geological conditions of the project area to analyze the possible water

and soil loss hazards caused in the engineering construction. During the construction

period of this project, if the construction organization does not take effective

protection measures, there will be new water and soil loss with the action of rainfall,

which will bring adverse impact to the project area and local land and water resources

and ecological environment. The main hazards are:

1. Possible hazards to the project's itself

Intensify water and soil loss and influence the engineering construction. The

removal of old ship lock, excavation of approach channel, ground leveling, foundation

pit excavation of buildings, layout pf temporarily built facilities, road construction

167


and layout of spoil area during the engineering construction, which disturb the

original soil layer, destroy the soil structure, seriously influence its stability, and

create conditions for the aggravation of water and soil loss. Especially for the large

area of exposed earth surface and the temporary stacking side slope for earthwork

dumping, if there is rainstorm, with the flushing and rain drops and surface runoff, the

sand will directly enter into the lock chamber and approach channel, leading to the

deposition of chamber and downstream approach channel, which will interfere the

pass-by of the ships and have extreme adverse influence to the construction and

operation of this project.

2. Possible hazards to the project's land and water resources

Accelerate the land fertility loss and reduce the land farming ability. During the

construction process, the original landform in the area will be disturbed, and the

aboveground vegetation and soil layer will be destroyed, which lead to the reduction

of organism, microorganism and their derivatives; thus the site conditions are

degenerating, which does not only influence the agricultural production and also

brings difficulties to the vegetation restoration and land rehabilitation.

3. Possible hazards to the project's ecological environment

The area of the disturbance earth's surface of this project is 14.58h ㎡ , and the

area of the damaged water and soil conservation facilities is 13.40h㎡. The disturbed

surface area and earthwork work amount of the engineering construction are large,

which will severely disturb the original land feature, destroys a large area of

vegetation, significantly reduces the anti-erosion ability of the topsoil, and extremely

easy to cause water and soil loss. In particular, the dumped mud filling of spoil area

might cause the increase of suspended matters in waters, other organic and inorganic

pollutants, which makes the service function of the water environment fall and leads

168


to the further degeneration of the ecological environment in the project area.

4. Possible hazards to the downstream and surrounding regions

It increases ditch deposition, which influences the downstream safety. The old

ship lock removal and approach channel construction process will produce a lot of

rocks, offscum, spoil and extra earthwork, which shall be delivered and stacked in the

spoil area; if the timely and effective construction management and protecting

measures are not taken, a lot of sand will be brought to the downstream ditches and

channel with the act of rainfall and surface runoff, which will lead to deposition and

be not good for flood discharging; it will aggravate the flood disaster, threaten the life

and property safety of the downstream people, and go against the harmonious

development of the surrounding region.

8.7 Measures to Control Water and Soil Losses

8.7.1 General Arrangement for Water and Soil Conservation Measures

On the basis of analysis and evaluation to the protection measures with water and

soil conservation functions to the main works, combine with the partition of

prevention and treatment areas, construction features different individual engineering

and the existing control measures, and put forward the water and soil conservation

measures in the zones. Via combination of water and soil conservation engineering

measures and vegetation measures, reasonably lay out, form complete water and soil

conservation measures and prevention and treatment system, and realize good

prevention and treatment effect.

for river bottom protection on the location near the ship lock head in the approach

channel; use placed rock fill for protection above the low water level of the upstream

169


and downstream of the flow separating bank; use precast concrete block for protection

on the side slopes of the upstream and downstream approach channel and the internal

side slope within a certain scope of the approach channel straightway; set the field

drainage measures on the earth filling platform on the sides of lock chamber.

Vegetation measures: plant both arbors and shrubs on the filled earth on both

sides of the lock chamber; plant arbors on the water side of the ship-parking platform

on the left side of downstream approach channel, and shrubs on the inside;

Provisional measures: upstream and downstream construction water retaining

cofferdam slope protection.

2) Embankment project area

upstream and downstream, use precast concrete grid grass slope protection;

Vegetation measures: sow grass seeds the bank platform and the side slopes,

combine with precast concrete grid for comprehensive protection, and the other bare

slopes use grass protection.

Provisional measures: carry out topsoil stripping before the construction, and

transport to temporary soil pile zone for storage and later for refilling and greening.

3) Highway bridge and wiring area

Engineering measures: use precast concrete block slope protection for the

protection of the side slopes of the connecting part between the highway bridge and

road, and set drainage works on both sides of the road.

Vegetation measures: plant grasses on both sides of the highway and the side

slopes of both sides, and plant street trees;


transport to temporary soil pile zone for centralized stacking; consider construction

170


period obstructs, covers and other temporary protection facilities.

4) Ship lock administration area

slope of the administration region for protection, set drainage ditch inside the walls,

and connect it with the embankment drainage system;

Vegetation measures: use arbors, shrubs, grasses around the buildings of the

administration area for greening and beautification.

Provisional measures: construction temporary drainage combines with

permanent drainage facilities, and particularly consider construction period obstructs,

covers and other temporary protection facilities.

5) Construction production and living quarters

Engineering measures: after the construction is done, remove the temporarily

built facilities and carry out land reclamation;

Vegetation measures: it shall be incorporated into the uniform consideration of

afforestation and beautification and ship lock administration area;

Provisional measures: set temporary drainage and de-silting measures around the

site.

6) Spoil area

Engineering measures: after the construction is done, carry out land reclamation,

second ploughing or recovery of original landform;

Vegetation measures: carry out vegetation recovery to the forests and grasses

within the land occupation;


transport to temporary soil pile zone for centralized stacking; set straw-earth

171


cofferdam around the mud-dumping area and consider the temporary drainage; and set

obstructs, drainage, de-silting and covers around the temporary soil pile zone.

8.7.2 Plant Selection

According to local natural conditions, greening purpose and protection goals,

select the varieties of trees and grasses with considering the water and soil

conservation function and the requirement of afforestation and beautification.

Considering that the excavation, backfill and stacking during the construction might

destroy the soil structure and make the soil infertile, the selection principles of

varieties of trees and grasses during the layout of plant measures:

① In order to enhance the greening survival rate, the local trees and grasses or

the ones have been widely used there shall be the first choice; they shall have strong

soil fixation and slope protection functions with thriving roots and tight grass sward.

It shall be trample resist and have strong expansion capability. It has strong

adaptability to soil and climate conditions. The plant diseases and insect pests shall be

lighter and easy to manage after planting.

② Follow the principles of environment protection and beautification, and the

evergreen tree shall occupy a certain proportion; if the conditions are permitted, the

construction organization can introduce some new trees and grasses to meet the

requirements of biodiversity and afforestation and beautification.

③ The tree selection shall be carried out according to circumstances by fully

considering the stress resistance of varieties of trees to make sure that the afforestation

project has continuous and stable effect and the soil fixation and protection functions

combines with environment effect; during the varieties of trees selection process, the

construction organization shall fully make sure that they have strong roots. Select the

beautiful and hygienic tree varieties and pay attention to the coordination between

layers. From the proportion between arbors and shrubs, the arbors will be the major,

172


and the grass will be auxiliary, which forms multi-storied greening; from the

proportion of the fast-growing and slow-growing, the slow-growing trees shall prevail

and reasonably use the fast-growing trees as compensation to get greening effect and

stable greening function as soon as possible.

Based on the principles above and field survey, the water and soil conservation

plan will select Magnolia grandiflora, camphor tree, cedar, populus tomentosa and

weeping willow as arbors, amorpha fruticosa, Buxus sinica and varparvifolia, leaf

privet as shrub trees, and Chinese rose and sweet-scented osmanthus as shrubby

flowers.

9.4 Environmental Supervision

Environmental supervision must be carried out for the project in accordance with

the requirements in “ Notice on Carrying Out Traffic Engineering Environmental

Supervision” issued by the Ministry of Communications, to positively conduct the

environmental supervision, so as to enforce clean production, minimize the damage

during construction and maximize the ecological restoration, making the project

satisfy the environmental requirements, and drainage of the noise, waste gas and

sewage reach the related standards. Guarantee the investment to environmental

engineering, making simultaneous construction and operating of the ecological

protection & restoration and water environment protection with the major project.

Environmental supervision is an important guarantee to carry out various

environmental measures, also an important supplement to the overall project

supervision dominated by the project quality, at the same time, it also lay a basis for

the proposed environmental protection completion acceptance.

Environmental supervision engineer (ESE) is an important role in overall

management and supervision level system. In this project, ensure ESE completely to

merge into the project supervision engineer system, which is to clearly assign the

environmental supervising duties and incorporate it into the overall project

supervision engineer contract.

Meanwhile the external environmental consultant (EEC) must be merged into

supervision system. EEC directly signs the contract with the project owner,

independent from the contractor and supervision engineer. EEC will assist the owner

to have training and consulting service, check the environmental measures of the

contractor and the supervision engineer, as well as compile the half yearly

environmental monitoring report required by the World Bank during project

execution.

201


9.5 Environmental Monitoring Plan

9.5.1 Purpose of Environmental Monitoring

Environmental monitoring includes construction period and operating period,

whose purpose is to completely and timely mast the pollution status of the proposed

project, understand the environmental quality change degree and affected scope of the

project construction to the area where the project is located as well as environmental

quality status during operating, timely feedback the information to the responsible

agency, so as to provide the basis for the project environmental management.

9.5.2 Monitoring Agency

Environmental monitoring during construction and operating includes noise,

water and ecology, with complicated monitoring personnel and instruments, therefore

it is suggested that the construction organization may entrust a qualified monitoring

agency to complete it.

9.5.3 Monitoring Scheme

1.Water quality monitoring

Monitoring for the project shall be carried out as construction areas and sections,

water quality monitoring points are mainly aiming at the production and domestic

wastewater and receiving water body for the wastewater. Location of the project,

composition of the project, number of constructors, wastewater volume and

construction duration are considered, to have important monitoring.

Flush point for the sandy stones on construction site. The wastewater firstly

enters the sedimentation tank, then is drained to Fenquan River. Arrange a monitoring

section at the exit, to monitor the water treated, once a month. The monitoring items

202


include COD, SS, etc.

Flush wastewater of the construction machines and vehicles firstly enters the oil

separation tank, then is drained to Fenquan River. Arrange a monitoring section at the

exit, to monitor the water treated, once a month. The monitoring items include COD,

SS, etc.

Arrange a monitoring section at the water back exit of mud-dumping area, to

have monitoring for the water backed, once a month. The monitoring items include

COD, SS, etc.

In addition, arrange a section in the upstream and downstream of Yangqiao ship

lock during operating, see Table 9-4 for the specific location of the section,

monitoring factors and frequency.

2.Environmental air monitoring

A monitoring point is set in the project construction area. According to the major

pollutants produced during construction and control index of air quality, the main

203


monitoring item during construction is TSP, with the monitoring period of once every

3 months.

3.Noise monitoring

A monitoring point is set in the east and west of the project construction area

respectively, with monitoring item of equivalent sound level day and night. Once

noise monitoring every month during construction, which is executed during

construction peak.

4.Soil and water conservation monitoring

Monitoring period: construction preparation - end of design level year

Monitoring frequency: rainfall of the area where the project is located mainly

concentrates in June-Sept. every year, with much rain and long duration, and the

storm is dominated. Therefore it shall monitor once each month in every May-

October, of which, June-September is the important monitoring period. If the heavy

rain or storm occurs, another monitoring shall be added, with yearly monitoring

frequency 8-10 times. Ground monitoring can be executed at any time as required by

data sampling, observe the soil loss after sedimentation. When the sediment load is

less, it may observe soil loss at an interval of time; if the rainfall isn’t continuous

within a day, with equivalent duration and intensity, no repeated monitoring is needed,

but the monitoring shall be enhanced during storm season; When the erosion process

monitoring is required, it shall observe the rainfall, runoff and silt simultaneously.

Ground observation for plant measures is arranged in spring and autumn separately.

Except for gravity erosion, investigation monitoring work shall be executed prior to

completion of flood season, which for other items will be done in dry season

principally. During each investigation, it shall fill in the investigation table, and

summarize and arrange them at end of the year. Based on the project analysis and site

survey, it is planned to have soil and water conservation monitoring for each

representative work organization.

204


5.Review and filing of the monitoring data

Monitoring data during construction shall be timely arranged and analyzed, to

raise the advice on improvement of the original environmental facility according to

the monitoring result. Various data obtained must be saved and managed with

computer, and the environmental monitoring data shall be concluded, arranged and

evaluated each year.

Set up quality review system for the monitoring data report, the data after review

shall be numbered for uniform filing and storage. During the project implementation,

stage report shall be provided by stages and reported to the local environmental

protection dept., so as to fulfill and check the environmental measures, which also

will be the basic data for regional environmental management and environmental

research in future, to effectively control the adverse environment effect unforeseen in

the project plan.

9.5.4 Environmental Investment

Construction of the project is beneficial to the development of the regional

shipping industry and regional economy. During construction, the waste water,

exhaust gas (TSP) and waste slag will produce a certain pollution to the environment;

the construction will damage the current vegetation and greening, accelerating the soil

and water loss. With the completion and operating of the construction, the ship

passing through the lock will cause noise and oily water, and the ship staff will

produce the domestic sewage and solid waste, and the lock office staff will produce

various waste, such as domestic sewage and household garbage, which will affect the

local environment if they are treated improperly. The dust produced by construction of

the ship lock and approach channel will exert a certain influence on the atmospheric

environment of borrow area, transportation road for waste soil and waste soil area. If

the necessary preventive measures are taken, the atmospheric environment will be

restored to the original level after completion of construction. During construction,

205


excavation of the underwater will increase the concentration of suspended particles of

water body, with bad influence on water quality for a short time. If the necessary

measures are taken and construction procedures are arranged reasonably, the influence

may be minimized. During construction, the construction machines may influence the

sound environment nearby the construction site, but it is hard to quantize this loss.

The influence may be relieved if the rational construction management measures are

adopted, even it will disappear after completion of construction. Protective green belts

shall be provided on both side of the approach channel, to reduce the influence of

noise during operating. If the defensive cost is considered as the economic loss caused

by resource destruction, its loss will be the green fees in environmental investment.

The land occupied by the project becomes water area, to expand the water area of lock

area and increase slightly the water evaporation, therefore the humidity of surface

layer will be increased, which shares the functions of air purification and temperature

regulation, but without obvious influence on rainy, windy and foggy climate. At the

same time, it is helpful for drainage and flood control. The environmental measures

such as protection slope and greening on both sides of the approach channel will

better control the soil and water loss. See Table 9-5 for the environmental investment

estimation. The environmental protection costs of the proposed project is about RMB

9.958 million Yuan and the total investment for project construction reaches RMB

161.66051 million Yuan, the former accounts for 6.2% of the latter.

Yangqiao ship lock is located in Yangqiao town of Linquan county, with about 26km from Linquan county; the

lock is on Linquan River, the left of Yangqiao flood diversion gate and check gate, with 36km from Hanwan gate

and 54km from Fuyang gate. Yangqiao lock was built in June of 1986 with approval from the provincial planning

commission, with lock level VI, lock dimensions 100×7.5×2.0m and the design carrying capacity 1000000 tons.

With the economic development of Linquan county, volume of the freight transportation is gradually increased year

by year, therefore it is imperative to expand the lock. In Nov. of 2006, Liquan county reported Letter of Yangqiao

Ship Lock Expansion Project in Linquan County to the municipal government, and the municipal government

reported it to the provincial development and reform commission. On Jan. 22 of 2009, Anhui Provincial

Development and Reform Commission officially approved the project, to build a new lock on the original site

according to grade V channel and 3000000 tons.

As required by the related national provisions, EIA shall be carried out for the project. In order to widely

understand the requirements, wishes and suggestions of the public on the project, making the project construction

more perfect in each aspect, and minimizing the environmental impact possibly caused and giving full play to the

social, environmental and economic benefits, we especially execute the public participation survey.

Your suggestions are of great important, so we cordially invite you to complete this survey, thank you.

living area?”, 110 ones chose water pollution, accounting for 91.7%; 71 ones chose

solid waste and household garbage, accounting for 59.1%, 19 ones chose air pollution,

accounting 15.8%, and the rest 58 ones chose noise pollution, accounting for 48.3%,

which basically reflects that the major pollution problems in the local rural

environment are water pollution, solid waste and household garbage, while water

pollution shows that the residents nearby Fenquan River worry about the water

environment most, at the same time, it also makes higher requirements for construction

of the project.

(5) For the question “What’s the most concerned environmental problem during

implementation of the project”, 74 ones chose soil and water loss, accounting for

61.7% of the total survey objects; 69 ones chose vegetation pollution and sludge

stench, accounting for 57.5% of the total survey objects, 59 ones chose water body

damager, accounting for 49.2%; 19 ones chose sludge disposal, accounting for 15.8%,

(2) Media publicity opinions statistics

During the media publicity, the assessment organization and construction

organization didn’t receive any feedback.

2. Survey results analysis in stage 2

(1)Opinions from the public along the project

According to the questionnaire statistical result in stage 2 and during the forum

and personal interview, the assessment group introduced in details the major report

conclusions and the environmental countermeasures and mitigation measures raised. It

can be learn that the public surveyed support the project, they think that it is

advantageous to the economy

We can see from the above statistical table that:

①Attitude to the project

About 100% surveyed objects support the project, they think that ship expansion

is advantageous to the local development and will strengthen the communication to the

outside.

②Analysis on the environmental pollution problems

The public shows great emphasis on the noise pollution during construction,

thinking that the construction at night will disturbs their normal schedule, and the

travel during construction, wishing the temporary road will satisfy the normal travel

requirements. After the assessment group described the environmental measures and

mitigation measures raised in the report, most of the public will accept the

environmental impact if the mitigation measure can be fulfilled.

10.4 Conclusion of the public participation

227


It is learned from the public participation survey results in two stages that the

public support the project generally, considering the project will improve the

navigation capacity of Fenquan River, with small influence on the living and working

environment of the residents nearby. At the same time, the public has clearly

understood the environmental impact caused by the project, showing great concern on

the ship construction noise and stench sludge. Meanwhile they think that the

environmental pollution problem produced is within the acceptable scope, and they can

accept the environmental impact after the environmental countermeasures and

mitigation measures raised in the report are implemented. The public wish that the

environmental pollution control and environmental management during construction

can be done well when the project is implemented, to realize the maximum

environmental, social and economic benefits, as well as the sustainable development

path.

228

Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 11. Conclusion of Assessment

11 Conclusion of Assessment

11.1 Project Overview

As an important part of Henan province and Anhui province as well as waterway

network in Huaihe River basin, Shaying River is the biggest branch of Huaihe River

and one of two trunk streams and three branches in the bone waterway network of

Anhui province, with planning grade IV. Fenquan River is the biggest branch of

Shaying River, with long history of navigation. Yangqiao lock in Fenquan River plays

a key role in deep water transportation network, as per the deep water economy and

traffic volume forecast result, the current channel situation and planning are shown:

construction scale of Yangqiao lock is grace IV channel, 500t, also 1000t, lock

chamber dimensions 200×13×3.5, the design annual through capacity 6720000t based

on Navigation Standard of Inland Waterway and Ship Design Code.

Total earthwork excavation volume of the project will be 760600m³ ， total

earthwork filling volume is 235700m³ and the discarded earthwork volume

504900m³. The discarded soil will be transported to the spoil area on the right bank

check gate to have centralized piling and disposal.

The project occupies 16.91h㎡ totally, including6.91h㎡ for the permanent land

and 10h㎡ for the temporary land, covering water, arable land, forest, grassland and

land for water facilities. The land for ship is within Yangqiao Ship Management

Office, no land will be added newly. The project will involve in demolition and

resettlement, we have entrusted engineering immigration research institute of Anhui

Traffic Vocational Technical Institute to compile Due Diligence Report for Yangqiao

229


Ship Lock in Shagying River Channel Regulation Engineering.

The total project investment will be RMB 161.6651 million Yuan, including

RMB 9.958 million Yuan for environmental investment, accounting for 6.2% of the

total investment.

11.2Current Environment Quality

1. Current air environment quality

Pollution index of SO2, NO2, PM10 a and TS in the air inside the assessment area

of the project is less than 1, indicating the environment air quality reaches grade 2 in

GB3095-1996 Environmental Air Quality Standard, and the regional environmental

air is good.

2. Current water environment quality

Various monitoring factors in each section such as pH, DO, petroleum and fecal

escherichia coli have reached class IV in Surface Water Environment Quality

Standard （GB3838-2002） . SS meets the dry crop limit value in Irrigation Water

Quality Standard （GB5084-2005); while the monitoring factors total nitrogen and

total phosphorus in 3 sections all exceed standard, excess multiple of the former and

the latter is 2.69 and 0.57 separately. Monitoring factors COD and BOD5 in 1# section

slight exceeds standard. The major reasons for this is that the domestic wastewater of

the residents along the Fenquan river s drained to it. The monitoring results show that

the current value of Fenquan river cannot meet grade IV standards in Surface Water

Environment Quality Standard （GB3838-2002）.

3. Current sound environment quality

230


We can learn from the current noise monitoring result that the current noise at 1#,

3# and 4# monitoring point on May 13 meets class 2 and 4a requirements in Sound

Environment Quality Standard （GB3096-2008), but the noise at 2# monitoring point

in day slightly exceeds standard, being 0.3dB(A), with the reason that the tractor

traveling on 017 makes a noise.

4. Settlement environment quality

Content of various heavy metal pollutants in settlement of Fenquan river is

below Pollutant Control Standard for Farm Sludge （ GB4284-84 ） . This kind of

settlement will be piled into green land or used for shelter forest after natural drying,

its heavy metal content won’t affect the growth of plants and the human health.

5. Investigation and assessment of the current ecological environment situation

No virgin forest, secondary forest and the natural reserve area approved by the

people’s government at each level is available with the assessment scope, nor the

extensive area, with good ecological environment quality.

Herbaceous plants are widely distributed in the farmland, roadside, ditches and

riverbanks within the proposed project, terrestrial herbs are dominated by dandelion

and wild artemisia; and herbaceous aquatic vegetation is common or rare species.

Woody plants mostly are the forest tree species artificially cultivated, without rare

wild plants protected by the state or province. Woody plants are dominated by the

little, acacia plants, cedar and paulownia. Variety and number of the wild animals

inside the assessment area is small, rodent specie is the dominant, with a large number

of yellow weasels. In this survey, we haven’t found the wild animals protected by the

state and the province. The assessment area is farming land, with good artificial

vegetation, dominated by wheat and soybean. Soil within the area is mortar black soil

and moisture soil; the land use type is farm land, soil erosion is water erosion, with

231


small erosion degree and scope.

6. Water and soil loss

According to Classification and Grading Standard for Soil Erosion, the project is

earth-rock mountain area in the north, water erosion for the soil erosion, including

surface erosion and gully erosion, the permissible water and water loss value is 200t/k

㎡·a. The compiling organization has surveyed the background value of water and soil

loss in the project area, there are a large amount crops and a few trees in the

construction area, poor erosion, with soil erosion modulus about 200t/k㎡·a, which is

basically satisfied after the survey made on site and communication with the local

department.

11.3 Environmental Impact Forecast and Assessment

11.3.1 Water Environment

(1) During construction

Production waste water discharge during construction includes increase of

suspended particles in surface water due to water construction; oily waste water

produced by dirty oil dropped or leaked from the construction machines and flushed

by rain of the exposed machines; waste water leaked from the bottom of construction

ship; pollution caused by rainwash of the piled building materials and waste, pit

foundation drainage and wastewater caused by flushing the construction aggregates;

the major pollutants are suspended matters and petroleum produce.

Direct discharge of the construction wastewater will produce certain pollution to

the lock river each. Pollution to the surface water can be effectively avoided or

lightened by means of isolation, settlement and strengthening the environmental

232


management during construction.

(2) During operating

Pollution during operating mainly includes the domestic pollution due to the lock

working staff and ship working staff during operating and oil pollution caused by

ship, the major pollution factors are COD, NH3-N and petroleum.

Based on the analysis in Chapter III, domestic wastewater caused by the lock

management office will be 1.3m³/dm, which is discharged after it is treated with

sewage well buried sewage treatment plant and met grade II standard in table 4 of

Integrated Wastewater Discharge Standard （GB8978-1996）. Household wastewater

discharge capacity of lockage ship shall be 1.0m³/d, household wastewater discharge

of the ship shall execute the related requirements in Ship Pollutant Discharge

Standards. Main functions of water body in Fenquan River section of the assessment

area are transportation and irrigation, without the intake for centralized drinking

water, with a small amount of household wastewater discharged on standard, therefore

it exerts small impact on the water environment of Fenquan River.

As required by the port and waterway management department, when a ship

passes through the lock, it is forbidden to discharge oily wastewater from bottom of

the cabin to water body. Then it won’t exert any oil pollution on the water body

during the ship passes through the lock normally.

11.3.2 Ecological Environment

The project is a functional area for dry crops inside the ecological zone along

Huaibei Plain. Types of land covering include water, arable land, forest, grassland and

water facilities, no living species protected is provided in the project and its

surrounding, with small water consumption. The project may damage the surface

vegetation, causing a certain degree of adverse effect, but the area of artificial

233


facilities is expanded, which will change the natural ecology process of partial region,

making the habitat of the land wild animals to be changed and decreased.

11.3.3 Analysis on Water and Soil Loss

A large amount of excavation, filling and temporary piling exist during

construction, which not only breaks the original vegetation, but disturbs the structure

of surface soil and change the current landform, then the new water and soil loss may

be easily produced under the function of gravity and rainfall. According to the water

and soil loss forecast results, total loss capacity possibly caused by the project will

reach 2081t, including 89t for the native water and soil loss and 1992t for newly

added loss.

Construction of the project is of good economic and social benefits and plays a

significant role in promoting the local social and economic development. Although it

will damage the original landscape, and the discarded soil and dregs also will cause

soil and water loss, yet the soil and water loss produced by it can be reduced by

working out the water and soil conservation plan, taking the corresponding

countermeasures and effectively control the water and soil loss possibly caused.

11.3.4 Atmospheric Environment


The fugitive dust in construction will exert the maximum influence on the

ambient air during construction; secondly, oil-fired exhaust produced by

transportation and labor equipment will also influence the atmosphere. Fugitive dust

in construction includes the directly discharged dust during construction and second-

time fugitive dust produced in wind or other dynamic conditions because of too much

construction surface soil. Construction fly dust of the project mainly comes from pit

foundation excavation, stockyard mining, discarded dregs piling and vehicle

transportation, the main pollutant is TSP.

234


The project construction will produce fly dust inside the project area and

construction roads, with a certain influence on the constructors touching dust for a

long time and the residents along it. Therefore the construction organization must take

the dust suppression measures, such as watering on the construction site, strength the

management measures and enhance the labor protection to the site constructors. These

measures will reduce fugitive dust for 50-70%, to effectively reduce the influence of

ambient air. Pollution of fugitive dust to ambient air is temporary and partial, it will

disappear after completion of construction.

Pollutants caused by transportation and fuel emission of some construction

machines are small, which is of the features of flow and diffusion, and there are good

diffusion and dilution conditions for air pollutants in the construction area, therefore it

won’t product the adverse effect on the quality and function of ambient air.


During operating, the ship will produce oil-fired exhaust and the pollutants such

as SO2, CO and NO2 during navigation, which will discharge along the channel. The

local air diffusion conditions are good, exerting no deterioration in the atmospheric

quality. The proposed project meets the standards and requirements of grade II zone in

Ambient Air Quality Standard （GB3095-1996）.

11.3.5 Sound Environment


Construction of the lock, highway bridge reconstruction and wiring will

influence the regional households. The construction area is located in the south of

Wanggao village, concrete mixing station and steel wood processing factory are inside

the lock management office. According to the site survey, the point sensitive to sound

environment nearby the project area is Wanggao village. In view of the high intensity

235


of noise source of the steel wood processing factory, it shall be established in a

temporary house during the project construction organization design, to insulate

sound and reduce noise. The minimum noise reduction of the temporary house is

15dB (A), and concrete mixing station completely meet the requirements; the steel

wood processing factory meets the standard in daytime, but at night, it is satisfied

only beyond 100m, so it is forbidden to process at night during construction, avoiding

the influence on the residents in Wanggao village.

Construction of lock engineering, highway bridge and wiring will exert a certain

of influence on the surrounding sensitive points, whose sound environment will

beyond the standard occasionally. But these noise sources are temporary during

construction, only with temporary and partial influence, which will disappear after

completion of construction.


Noise due to ship navigation is small, which is mainly the flow sound source.

During the operating, noise when the ship passes though the lock is small, with small

influence on functions of the sound environment. The ship shall be equipped with the

effective muffler, and keep its normal operation. Noise emission standard shall satisfy

Noise Level Provisions for Inland Ship.

Noise from the ship horns and the loudspeaker for command operation on site is

of the features of intermittent and sudden, with great influence on each sensitive

point. For this kind of noise, it must take various means to lighten the effect on the

surrounding environment as far as possible. When the ship passes through the lock,

sound device shall be provided according to the regulations on ship safety navigation,

and it is forbidden to whistle at random. Volume of the loudspeaker for command

operation on site shall be controlled in daytime, and horn won’t be used at night for

commanding, it is better to apply on-site command way. .

236


11.3.6 Solid Waste

Solid waste from the ship expansion project during construction mainly is the

household garbage caused by the earthwork excavation and the constructors. Total

earthwork excavation of the project reaches 343700m³（including the discarded dregs

24800m³ from removal of the old lock and management office, and 2800 m³ for the

topsoil stripped), total earthwork filling capacity 218300m2 and discarded earthwork

125400m³. There is 24500m³ construction waste from removal of the old lock in the

discarded earthwork, all the discarded earthwork is transported to the spoil area for

centralized storage and disposal to the right bank of check gate. On the basis of

1.0kg/man·day, the household garbage produced by the constructors during

construction totals 120t.

Comprehensive utilization of the discarded soil and dregs will be combined with

the current new rural construction, the old lock can be used for construction of tractor

road and the discarded soil can be used as the raw material of bricks and tiles plant.

Before use of the temporary discarded soil and dregs, soil and water loss control

measures for the temporary excavation area must be done well according to the soil

and water conservation plan of the project.

Linquan Water Supplies Bureau approved the spoil soil site of Yangqiao lock

expansion project.

Solid waste during the operating mainly comes from the domestic garbage

produced by the lock management personnel and the workers on ship. On the basis of

1.0kg/man·day, 4290kg/a garbage will be produced from 13 on-duty lock working

staff. The domestic garbage during construction and operating will be collected and

transported to the city sanitation department for landfill disposal.

For the domestic garbage produced by the working staff on ship, “it is forbidden

237


to discharge the ship waste to inland waters. Ship waste must be accepted and

disposed by the qualified organization” is clearly specified in Environmental

Management Provisions on Inland Waters Pollution Prevention by Ship of The

People’s Republic of China. The ship shall be equipped with waste storage containers

with cover, free from leakage or overflow, or collect the waste in bags, to classify,

collect and store the waste produced, so as to meet the requirement of ship waste

storage during navigation. It is forbidden to use any disposal foaming plastic

tableware that cannot be degraded.

11.3.7 Accident Risk Analysis

After the project is completed, it will effectively increase the ships passing

through Yangqiao lock, improve the navigation capacity of Fenquan River. But due to

accidental factors, collision or sinking may be caused. According to the freight

forecast during operating and the related statistical results, most of the ships in and

out are coal, building materials and chemical materials, sinking of coal and building

materials will exert small influence on the water body, but that of the chemical

materials will influence the water greatly. During the environmental impact

assessment, we shall make risk analysis on the chemical materials transportation.

According to the probability calculation for ship collision, it shows that the

possibility of collision is less; but according to the principle of probability theory, this

small probability accident may occur. And once it occurs, it will produce the serious

destructive effect on the waters, such as: kill the fishes in river, poison the organisms,

do harm to the downstream intake. Therefore once a chemical material accident

occurs, it will product great effect.

11.4 Environmental Protection Measures

238


11.4.1 Environmental Protection Measures during Construction

1. Water environmental protection measures

For the construction slurry wastewater produced by aggregate flushing, concrete

mixing and construction site during construction, the temporary facilities must be

built, such as collecting tank, settlement tank, oil separator and drainage ditch. The

waste and sewage shall be collected separately and discharged after it enters the

sewage treatment device and is treated in the oil separator and sedimentation tank.

Construction ship shall be provided with oil-water separator or oil receiving device, to

discharge the wastewater after treatment. Strengthen the safety production education

for the constructors, regularly maintain and timely repair the construction equipment,

to avoid water environmental pollution because of accident during construction.

2. Atmospheric environmental protection measures

In order to prevent dust, move the discarded soil and dregs from the site timely, cover

the surface of yellow sand and cement, water the construction site and roads to

effectively reduce the fugitive dust. Tires of the transport vehicles must be cleaned

immediately.

For the roads for soil and slurry transportation, special persons shall be provided to

check and clean them, to guarantee their cleanness. Wind shield shall be provided

around the aggregate stacking yard, and location of the stacking shall be arranged

reasonably, to reduce the fly dust possibly caused. Broken bag or the cement scattered

on ground shall be timely cleaned. The road entering and leaving the stock yard shall

be watered, keeping its moisture, or lay bamboo basketry or straw bag on it, to reduce

the fugitive dust caused by the vehicle passing by or wind. The cement shall be saved

in a special warehouse, cement scattered on ground shall be timely cleaned. Enclosed

operation is adopted on the construction site, guardrail and barrier are provided

around the site, to reduce the influence of fugitive dust on the surrounding. Cover or

239


water the excavated soil, and timely carry it away.

3. Sound environmental protection measures

Reasonably arrange the construction time. Construction shall be executed in

daytime nearby the residential area, to reduce the strong noise machine on the

residents around. It is forbidden to use the mechanical equipment not meeting the

national noise emission standard and choose those with low noise, to reduce the noise

influence degree and scope of the major construction machines. Strengthen the

maintenance and repair of construction machines, stop the noise due to improper

maintenance. The mixing station shall be far away from the residential area, with a

sound proof wall. When the old lock is to be exploded, strengthen the security, and

inform the residents nearby in advance. Strictly prohibit the constructors and residents

nearby to stay in the blasting area, avoiding a hearing damage. Reasonably arrange

the driving route and time of construction vehicles to enter or leave the site, with

limited speed. Strengthen traffic management for the transport vehicles around the

construction area, whose number of horns shall be minimized, to avoid traffic noise

increased to the surrounding due to congestion. Strengthen civilization construction

and provide noise shield: provide a movable simple noise shield nearby the noise

source and a containment barrier on construction area, to shorten the affected distance

of noise transmission.

4. Solid waste disposal

Solid waste from earth excavation and demolition shall be reused as far as

possible, the underwater part of construction cofferdam unavailable and the sludge

shall be stacked in the appointed stockyard. Cover the surface mellow soil of original

bottom land on drying sludge or discarded soil, making the surface soil have good

performance. During cofferdam filling and leveling of cover soil in stockyard, dig a

trench for drainage and slope protection must be done well, to avoid water and soil

loss. After leveling, the stockyard will be used as a land for greening. Construction

240


waste and domestic garbage shall be collected and regularly cleared, to transport to

the refuse landfill.

5. Ecological environmental protection measures

Surface excavation shall be minimized during construction, to lighten the

damage to surface plants. Control the slope surface and gradient formed by

excavation as required by soil and water conservation, avoid construction in the rainy

season. After completion of the project, clean and level the temporary construction

site timely, to restore the original functions as far as possible. If it fails, plant trees and

grass. Strengthen the control measures for water and soil loss on the spoil area. To

reduce the influence of water and soil conservation, slow down the side slope as 1:4.

After the discarded soil is stacked well, leveling and greening measures must be taken

as quickly as possible in spoil area and its nearby places, to reduce the influence of

water and soil loss. Plant a large area of trees, flowers and grassland within the project

management area, to prevent water and soil loss.

11.4.2 Environmental Protection Measures during Operation Period

The household garbage shall be collected and transported by the sanitation

department to the garbage disposal plan for landfill. Domestic sewage of the lock

management area is discharged to the downstream after it meets grade 2 in Integrated

Wastewater Discharge Standard （GB8978-1996）with treatment by buried sewage

treatment facility (bio-contact oxidation + disinfection). Strengthen the publicity and

education for the shipping personnel, enhance the supervision and management of

domestic garbage on ship and discharge of oily wastewater, install oil-water separator

on the ships in and out, and prohibit to directly discharge the ship domestic

wastewater and oily sewage to the lock area without treatment. It is forbidden to

discharge ship garbage to water. Ship engine shall be equipped with effective silencer,

and guarantee it to work normally. The noise emitted shall satisfy Noise Level

241


Regulations for Inland Ship. For the high noise from the horn on site and ship horns,

various means must be taken to reduce the influence on the surrounding environment.

When different ships are passing through the lock, horn shall be used as per the

related provisions for ship safety navigation, random whistling is forbidden. Volume

of the horn on site shall be controlled in daytime, which won’t be used at night,

adopting on-site command mode.

11.5 Public Participation

In May of 2009, Anhui Provincial Academy of Environmental Science carried out

three times of public participation adopting media publicity, department visit and

questionnaire survey when compiling EIA Report on Yangqiao Lock Expansion

Project on Fenquan River. The first is at early EIA (May 11-21, 2009), to give a notice

in form of media publicity in Fuyang Local Marine Bureau website at early EIA );

The second time is to have a survey for the governmental departments and residents

along the project in form of posting up a notice and questionnaire survey before the

report is formally compiled. 120 questionnaires were issued and 120 ones were

returned, with 100% recovery rate. The survey involves in the residential areas and

organizations around the project construction area as well as the pubic possibly

affected nearby; the third time is to give a notice in form of media publicity on

Fuyang Local Marine Bureau website after completion of the first draft of EIA Report

(version within Anhui province ) (June 15-25 of 2009).

Feb. -June of 2013. After authorization, the assessment group again has executed

the public participation for twice in form of media publicity, department visit, post up

a notice, questionnaire survey and forum according to the related requirements of

World Bank in public participation and on the basis of Environmental Impact Report

on Yangqiao Ship Lock Expansion in Fenquan River, including: in the early of May of

2013, executed the public participation again for the governmental departments and

242


residents along the project in form of department visit, questionnaire survey and

forum, to understand the opinions on the environmental impact and requirements of

environmental measures from the public. We issued 100 questionnaires and returned

94 ones.

After completion of the EIA report draft (World Bank version), it is published in

form of media publicity on the websites of Transport Department of Anhui Province,

Fuyang Local Marine Bureau and Anhui Port Construction Investment Group, and the

complete report is saved in Yangqiao ship lock management office. The citizens may

obtain and read it, to increase the approach and degree of familiarity to the project.

The contents published include the main assessment conclusions and environmental

measures of EIA (World Bank version), to fully take the opinions and advices from

the representative directly affected by the project, and widely seek for advices from


It is learned from the public participation survey results in two stages that the

public support the project generally, considering the project will improve the

navigation capacity of Fenquan River, with small influence on the living and working

environment of the residents nearby. At the same time, the public has clearly

understood the environmental impact caused by the project, showing great concern on

the ship construction noise and stench sludge. Meanwhile they think that the

environmental pollution problem produced is within the acceptable scope, and they

can accept the environmental impact after the environmental countermeasures and

mitigation measures raised in the report are implemented. The public wish that the

environmental pollution control and environmental management during construction

can be done well when the project is implemented, to realize the maximum

environmental, social and economic benefits, as well as the sustainable development

path.

243


11.6 Comprehensive Conclusion

Yangqiao lock is one of the major hydraulic structures in Fenquan River pivotal project,

which directly affects water traffic of bulk cargoes of Linquan County. Water transportation

route starts from Fenquan River via Shaying River, and enters Huaihe River, finally reaches

Yangtze River via Beijing-Hangzhou canal. The expansion project will obviously improve the

shipping conditions of Fenquan River, speed up the material circulation and promote rapid

development of regional economy. After the analysis made on the various environmental

impact factors, the assessment considers that the most important environmental problem of the

project comes from the adverse environmental impact caused by discharge of wastewater,

noise, exhaust and solid waste during construction and operating to the affected area of the

project, which shall be effectively avoided or lightened after necessary environmental

measures. Construction of the project satisfies the requirements in Anhui Provincial Inland

Shipping Development Plan, Urban Maser Planning in Fuyan, Overall Planning of Fuyang

Port (2008-2025) and water conservancy development outline （ 2006~2010 ） in Linquan

county during the 11th Five-year Plan. Yangqiao lock expansion project will exert no adverse

effect on the current riverway and flood control nearby Linquan, and it conforms to the related

planning. Site of the lock meets the master planning of Yangqiao town. Arrangement of the

lock and the water facilities will not interfere with each other, no basic farmland will be

occupied. Power supply and water supply system are guaranteed, therefore the project site is

feasible. The public participation results show that the public supports Yangqiao lock

expansion project.

In general, the establishment of the project will have favorable social, environmental and

economic benefits. Its construction is feasible in view of environmental protection.
