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

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 River before the Ni River Mouth is called as Fen River, and the part after is called as
21 Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 2 Engineering Overview
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.

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
23 Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 2 Engineering Overview 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.

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 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 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 27 Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 2 Engineering Overview 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 hinterland, particularly the continuous improvement of the productivity of Linquan Chemical Industry Co., Ltd., and the continuous development of agricultural &
28 Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 2 Engineering Overview 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 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 29 Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 2 Engineering Overview 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.

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
31 Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 2 Engineering Overview
Gate and is mainly used for allowing the ships to pass; the Yangqiao Ship Lock is one 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.
32 Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 2 Engineering Overview
As the upper water level of Yangqiao lock is mainly controlled by the Yangqiao 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
33 Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 2 Engineering Overview
2.4.1 Lock construction scale
After expansion is completed, Yangqiao lock is Grade IV, the maximum ship 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.
1、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, 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,
34 Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 2 Engineering Overview 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.

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.

3.1.3 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
58 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
minimized, which is mainly reflected in the reasonable ship lock position arrangement 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;

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 61 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
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.
62 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
Table 3-4 Amount of Domestic Sewage Generated in Construction Period
Amount of domestic Amount of COD Amount of NH3-N Man-day sewage generated generated generated
120,000 man-days 9600m³ 2.88t 0.384t
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
63 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 include: the site leveling, earth excavation& filling and loading/unloading of building 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.
Table 3-5 Pollutant Discharge Status of Vehicle
Amount of pollutant Amount of pollutant Type Discharge amount of 8 t discharged discharged diesel lorry Pollutant (g/L of gasoline) (g/L of diesel)
SO2 0.295 3.24 81.51
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,
64 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 bulldozers, excavators, loaders, land levelers, concrete mixers, etc., have the noise 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.
65 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
The Water Bureau of Linquan County approved the location of the waste earth 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
66 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 the basis of 100 L of domestic sewage generated by each person per day in the ship 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
67 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
Grade II in Table 4 of Integrated Wastewater Discharge Standard (GB8978-1996); the 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.

13 429.0、429.0 128.8、64.4 17.1、10.7
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
68 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 economic & social benefits.
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
69 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 standard has limited impact to the water environment, and it will not 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 70 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 standard of Environmental Quality Standards for Noise (GB3096-2008); Wanggao 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 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, 84 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 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
85 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 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.

102 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 longer than that in Scheme I, and the water flow condition in the approach channels is
103 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 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

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 layout is shown in Figure 7-1.
107 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
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.

(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.

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 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. 112 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
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 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
113 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 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.
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 114 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 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 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
115 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 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 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 will.
(2) Carry out regular salvage and cleaning to the floating objects under the
117 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 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:
(1) Land occupation impact: permanent land occupation is mainly for approach channel dredging and bridge reconstruction works, including flood land occupation; 118 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 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.
Meanwhile, with the implementation of slope protection works, the approach channel afforestation and slope protection engineering can improve the water and soil
119 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 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 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 120 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 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 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, 121 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 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 excavation area: carry out topsoil stripping before the construction, and transport to
123 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 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 approach channel during the construction period, but this influence is temporary and
124 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 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 spots.
125 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
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
Due to the pollutant volume discharged from fuels out of transportation and 126 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 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 site to wash the vehicles when leaving the site and not bring mud and sand out of the 127 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 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 exhaust gas, including SO2, CO, NO2, in the way of linear emission along the
128 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 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).

129 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
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).
131 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
The ship lock and highway bridge reconstruction and wiring works will have a 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
132 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 fastening mechanical equipment, excavation and earth moving machinery, such as 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.
133 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
(6) The electric saw, electric planer, agitator, fixed concrete delivery pump, large-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:
1+α (Lp) i= (Lw) i+10lg (Ni/ViT) +10lg (D0/D) -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) 134 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
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.
Tab. 6-4Lockage Vessel Noise Source Intensity Table dB (A)
300t ship 500t ship Running speed Cabin door opens Cabin door closes Cabin door opens Cabin door closes

The sound level of prediction spots shall be calculated based on:
0.1(L ) 0.1（L ） (LAeq)Prediction=10lg[10 Aeq Total+10 Aeq Background]
Where: (LAeq) total····· the sound level total of noise pollution sources received by the prediction point, dB (A);
(LAeq)Prediction····· the noise predicted value of the prediction point at day or night, dB (A);
(LAeq)Background·····Current situation background value dB (A).
Carry out the prediction based on the most adverse condition (open cabin door
135 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 and large-tonnage ship lockage conditions); and see Table 6-5 for the noise sound levels of the noise sensitive spots of the lockage ship.

Day 50.1 52.22 60 Wanggao Village Night 44.7 49.1 50
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. 136 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
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 137 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 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
138 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 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
139 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 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. 140 Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 7.

142 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 held in sealed containers; after shipwreck, leak is unlikely to occur, but timely 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.

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.
145 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
Tab. 7-1 3Cumulative Impact Types
Type Key feature Example

Composition Impact caused by multiple impact sources or 6 Synergistic effect between pesticides effect many paths
Indirect Business development of highway 7 Secondary effect influence construction induction
Trigger and System behavior and structure have 8 Global climate change threshold value fundamental change
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
146 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 radius of around 100m, which imposes a certain impact on economic efficiency of 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.
③Cumulative effects on the water environment: the cumulative effects on the water environment 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.
148 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
2) Impact on aquatic organism
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.
149 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
(3) Cumulative impact analysis of water environment
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.

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 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
151
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 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.
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
152
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 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.

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 and layout of spoil area during the engineering construction, which disturb the original soil layer, destroy the soil structure, seriously influence its stability, and
166
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 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 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
167
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 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.

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,
202
Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 9. Environmental Management & Monitoring 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.

(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 224
Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 10. Survey Analysis on Public Participation 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
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 225
Environmental Impact Report on Extension Engineering of Yangqiao Ship Lock of Fenquan River – Sub-project of Anhui Shaying River Channel Improvement Engineering 10. Survey Analysis on Public Participation 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.
226
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 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 227
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 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
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.
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
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 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
229
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 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 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

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 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

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
(1) During construction
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.
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.

235
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 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.
