1. General
1.1 Background and Scope of the Project
The Shaying River has a very long history of water transport. Since antiquity, its
water transport has been in a constant process of suspension, improvement and resumption.
From 2012 onwards, a three-year-long improvement effort began for the length of the
Shaying River in Anhui. As the last ship lock in the downstream navigation channel, the
Yingshang Ship Lock passed the EIA acceptance test of the Anhui Provincial
Environmental Protection Department in July 2012. With the completion and
commissioning of the Fuyang Ship Lock, navigation for the whole stretch of the Shaying
River has resumed. As the existing Yingshang Ship Lock is inadequate to meet the
navigation requirements, a new bottleneck problem stands in the way of greater transport
capacities. In order to cope with the pressing demand for inland navigation, Anhui
Provincial Port & Shipping Construction Investment Group (hereinafter referred to as
“APPSCI”) has proposed to expand the capacity of the existing Yingshang Ship Lock. The
proposed Yingshang 2nd Waterway Ship Lock Project (hereinafter referred to as “the
Project”, “the Proposed Project” or “the Work”) is an extension of the existing Ship Lock
as well as a subproject of the Shaying river channel improvement project financed by a
World Bank loan. Anhui Provincial Department of Transport has included the Project in its
12th Five-Year Water Transport Development Programme and the Anhui Provincial
Development & Reform Commission has officially approved the proposal submitted by
APPSCI.
The Proposed Project is to be sited on the right of the existing Yingshang Suice Gate
of the Shaying River channel, or more precisely, on the diversion dam between the
Yingshang Sluice Gate and the existing Yingshang Ship Lock. It is located 80km from the
upstream Fuyang Ship Lock and 45km from the downstream Mohekou Town. The
geographical location of the Project is shown in Att. 1 and Fig. 1-1.
The Project is to be built against Grade IV navigation channel standards, with a
design tonnage of 500t (up to 1,000t) and a maximum annual unidirectional navigation
tonnage of 12 million tons. The lock chamber has a dimension of 200×23×4.0m
(Length*Width*Water Depth at Lock Sill). The upstream and downstream approach
channels have a length of respectively 540m and 760m. The upstream approach channel,
measuring 80m across at the bottom, is shared with the Single Waterway Ship Lock. The
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Ship Lock
2
downstream approach channel is built independently and measures 40m across. A new
ship lock management facility will be built. 300.34m of bridge renovation work will also
be involved. The total area of the Project is 50.26hm2, including an additional 49.45 hm2
for the Work. The additional area includes 9.90hm2 for permanent uses (intended
primarily for hydraulic engineering purposes; it comprises 0.81hm2 for the Single
Waterway Ship Lock and an additional 9.09 hm2) and 40.36hm2 for temporary uses
(dominated by tidal flats, arable land and construction-purpose land for the Single
Waterway Ship Lock).
The Project involves 2.1169 million cubic meters of cut work (including 118,300m3
of overburden soil stripping and 2,400m3 of rubble generated by the demolition of the
existing management facility and the renovation of a bridge), a total backfill work of
644,400m3 and a total spoil work of 1.4725 million cubic meters. 13,500m3 of
overburden soil will be dumped in two temporary spoil areas, 3,300m3 of overburden soil
will be dumped in a corner of the Site of the Project (hereinafter referred to as “the Site”),
101,500m3 of overburden soil will be dumped in a corner of the spoil areas, 2,400 m3 of
rubble will be used for subgrade fill and the remaining 1.3518 million cubic meters of
spoil will be transported to the spoil areas. The actual total spoil work is 1.3518 million
cubic meters, which will be transported to the spoil areas. The planned construction period
is 30 months and the total investment is RMB274.3706 million.
1.2 Environmental Protection
As stipulated by construction project environmental management procedures and
applicable national environmental protection laws and regulations, APPSCI employed
Beijing Zhongzi-Huayu Environmental Technology Co., Ltd. (hereinafter referred to as
“ZHET”) to prepare the Environmental Impact Assessment Report on the Shaying River
Yingshang 2nd Waterway Ship Lock Project (domestic edition; hereinafter referred to as
“the EIA Report” or “Report”) in March, 2013 at the feasibility study stage of the Project.
The EIA Report was approved by Environmental Protection Department of Anhui
Province. In order to further control the quality of the Report and fulfill the World Bank’s
requirements, ZHET made further changes, supplements and revisions to the
Environmental Impact Assessment Report on the Yingshang 2nd Ship Lock Project as a
Subproject of the Shaying River Channel Improvement Project in compliance with the
requirements of the World Bank’s procedures. World Bank’s experts reviewed the Report
in January 2014, making comments on the basis of which ZHET made further revisions.

1.7 Focus of Assessment
The focus of the assessment of the Project is on (1) the environmental impact during
the construction period and environmental protection measures taken in accordance with
the severity of the impact; and (2) the environmental impact analysis for ambient noise
emissions and water pollution during the operation period.
1.8 Assessment Period
The assessment period may be the construction period or the operation period,
depending upon the characteristics of the Extension Project.
Construction Period (30 months): Dec. 2013 to May 2016.
Operation Period: 2022 (mid-term) and 2030 (long-term).
1.9 Environmental Protection Targets
1.9.1 Ecosystem Protection Targets
According to field investigation, no important cultural relics or ancient trees or other
precious faunal or floral species listed for protection have been found around the Site. The
vegetative cover on any permanent or temporary land of the Project comprises very
common local natural or artificially-grown plants. There are no basic farmland protection
areas, woodlands or rare species on the brink of extinction which require special
protection. The targets of ecosystem protection are primarily the local ecological
landscape, surrounding agricultural ecosystem and aquatic ecosystem.
1.9.2 Protection targets for Aquatic Environment Protection
According to field investigation and information provided by the relevant authorities,
there is no potable water intake near the Site and local villagers depend primarily on
groundwater and municipal running water for sources of potable water. The Project
involves primarily the Shaying River, which is currently used for agricultural purposes and
plans to be used primarily for industrial purposes. See Fig. 1-1 for the aquatic environment
quality of the Shaying River.

According to field investigation, the primary protection targets for noise and
atmospheric pollution control are villages and schools near the spoil areas, villages and
schools along the haul road for spoiling, and environmentally sensitive areas within the
scope of Site assessment. There are totally seven such areas, four of which fall into the
scope of the operation period. Tab. 1-15 details these environmentally sensitive areas. Fig.
1-2 illustrates their present situation. Figs. 1-3 and 1-4 illustrate the location of the

2. Related Engineering Overview
2.1 Anhui Shaying River Channel Improvement Project
For realization of the channel development objective, and taking account of the
current engineering conditions as well as the construction progress in Henan Province and
Anhui Province in the past, Anhui Province has been implementing the Anhui Shaying
River Channel Improvement Project in length of 206km to national standard Class IV, and
the planning for the Project started from 2012. The improvement covers 206km long river
channel with design navigation channel width of 50m, minimum design navigation water
depth of 2.8m, and minimum bending radius of 330m. The main components of the
Project include river channelization and dredging works, reconstruction of cross-river
bridges causing impediment to navigation, embankment seepage prevention, bank
protection, service areas, anchorage areas and navigation aids. The construction works for
anchorage area include both upper anchorage and lower anchorage at Yingshang Ship
Lock. The upper anchorage at Yingshang Ship Lock is located at upper stream 1.3km from
Yingshang Ship Lock, at right bank K158+300 of Shaying River, being in length of 514m,
and being 125m away from centerline of navigation channel; The lower anchorage at
Yingshang Ship Lock is located at lower stream 2.4km from Yingshang Ship Lock, at left
bank K162+700 of Shaying River, being in length of 794m, and being 135m away from
centerline of navigation channel. The anchorage areas mainly serve for safe anchor and
navigation of vessels at waiting time for lock. Up to December 2013, construction works
for upper anchorage at Yingshang Ship Lock has not started, while excavation of
earthworks for construction of lower anchorage is under way. Due to possible time
overlapping between construction duration for upper & lower anchorage at Yingshang
Ship Lock and that for this Project, it is recommended to make overall consideration while
arranging the construction works.
2.2 Yingshang Lock Junction
Yingshang Lock is located at the east of the county town of Yingshang, being 80km
away from Fuyang Lock at upper stream, and 45km away from Mohekou in lower stream.
It is comprised by Yingshang Regulating Lock, Yingshang Ship Lock (single waterway
lock), spillway and access bridge.
2.2.1 Yingshang Regulating Lock
Yingshang Regulating Lock was put into operation upon completion in July 1981.
Being the last-tier junction at lower stream of Shaying River, this Regulating Lock is
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Ship Lock
26
located in curve cut-off section of main river channel. It is consisted of lock chamber,
spillway, access bridge, and approach bridge of spillway. It has 24 openings and flat
bottom, in open reinforced concrete structure. Each opening is in clearance width of 5m,
therefore the discharge width is 120.0m. The top elevation of its base slab is 18.86m.
Approach bridges exist at both sides of the lock. Elevation of opening bottom of the
approach bridges is 25.00m. When water level above the lock exceeded 25.00m, water
would be discharged through the openings of approach bridges at both sides. Design
discharge volume of the Regulating Lock: 5000m3/s in 100-year recurrence interval.
The Regulating Lock has the function of flood prevention and drainage, water storage
level adjustment, as well as farmland irrigation within irrigation area of Yingshang Lock.
Statistics data from Yingshang Lock Management Office indicates that irrigation water
supply reaches 134 million m3 in June-September, 2013, which was the time for rice
transplanting and fostering.
2.2.2 Control scheme of Yingshang Regulating Lock (Yingshang Lock)
As prescribed in Yingshang Lock Control Application Rule (2013), Flood Control &
Drought Relief Headquarter of Fuyang Municipality shall come up with its control
proposal, and submit the proposal to Flood Control & Drought Relief Headquarter of
Anhui Province for approval, and Huaihe River Channel Management Bureau of Anhui
Province shall be responsible for control and operation of Yingshang Lock. As for other
controls, Flood Control & Drought Relief Headquarter of Fuyang Municipality shall
conduct control in collaboration with Huaihe River Channel Management Bureau of
Anhui Province. When necessary in special cases, Flood Control & Drought Relief
Headquarter of Anhui Province may conduct control. In accordance with the control
scheme, normal water storage level above Yingshang Lock is 24.0~24.5m (measured in
Abandoned Yellow River Elevation System); during dry season and water consumption
peak period, water storage level may be increased to an extent as appropriate. In the event
of massive water coming from upper stream, or heavy rainfall in the forecast interval, and
water level above lock chamber exceeding normal water storage level, the opening degree
of lock shall be gradually increased for purpose of pre-discharging flood. Besides, as
instructed in the “Approval on Adjustment of characteristic water level for flood control
above Zhaoji Lock, Fuyang Lock and Yingshang Lock (Ref. No.: Shengfangzhi
[2012]46)” issued by Flood Control & Drought Relief Headquarter of Anhui Province,
characteristic water level for flood control above Yingshang Lock is: prevention water
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Ship Lock
27
level 24.8m, warning water level 26.5m, and safety water level 28.45m (all measured in
Abandoned Yellow River Elevation System).
2.2.3 Yingshang Regulating Lock Reinforcement
Yingshang Regulating Lock Reinforcement has been listed as one of the national
major water lock reinforcement projects. Huaihe River Channel Management Bureau of
Anhui Province has designated Fuyang Hydraulic Plan and Design Institute to work out
“Preliminary Design Report on Yingshang Lock Reinforcement in Anhui Province”. The
reinforcement tasks for Yingshang Regulating Lock include: dismantling and
reconstruction of access bridge, construction of new hoist room in frame structure;
dismantling and reconstruction of bridge tower; dismantling and reconstruction of access
bridge and approach bridge of spillway; construction of a new small hydraulic block
power plant at the location of approach bridge of existing spillway; repair of bank
protection; erection of 2 new bulkhead gates; anti-carbonization treatment for side pier at
lower stream of lock; replacement and repair of bottom waterstop and partial side
waterstop; repair of piezometric tube; provision of anti-collision pontoon. As required for
navigation clearance of 2nd waterway ship lock, it is necessary to lift up elevation of
approach bridge of spillway at right bank of Yingshang Regulating Lock, as well as
elevation of partial deck of access bridge of Yingshang Regulating Lock. Among the
construction tasks, approach bridge of spillway at right bank of Yingshang Regulating
Lock shall be dismantled and reconstructed, partial deck of access bridge in length of 35m
shall be lifted up for 0~500mm. It is recommended that transport authorities should
enhance coordination.
2.2.4 Relationship between Yingshang Regulating Lock and Yingshang Ship Lock
Yingshang Regulating Lock was put into operation upon completion in July 1981.
Being the last-tier junction at the lower stream of Shaying River, this lock has 24 openings
in open reinforced concrete structure. Each opening is in clearance width of 5m, therefore
the discharge width is 120.0m. Top elevation of its base slab is 18.86m. The Regulating
Lock has the function of flood prevention and drainage, water storage level adjustment, as
well as irrigation water supply for 300,000 Mu farmland. It has played a significant role in
regulation and reduction of peak flood for middle stream of Huaihe River. Yingshang Ship
Lock is located at right side of the Regulating Lock, connecting to approach bridge of the
C Lock at east side, and crossing the flood control bank at west side. Construction work of
the Ship Lock commenced in September 2005 and completed in 2008, and it has been
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Ship Lock
28
opened to navigation upon completion. The Ship Lock has the function of allowing pass of
vessels. As the Ship Lock is a part of the Yingshang Lock Junction, the check flood level
adopts that for 20-year recurrence interval. The Ship Lock has no function of flood
discharge, and it does not occupy the discharge section of the river channel or the junction.
The Ship Lock causes no compact to flood discharge of the junction.
2.2.5 Operation status and problem of Yingshang Ship Lock
After Fuyang Ship Lock was completed and whole channel of Shaying River was
re-opened to navigation, waterway transportation volume through channel of Shaying
River has been increased sharply. In 2012, the waterway transportation volume through
channel of Shaying River reached 11 million tons, increased by 83.3% over the year of
2011. At Yingshang Ship Lock-the last-tier lock in channel of Shaying River to Huaihe
River, the cargo volume in 2012 reached 7.7 million tons, which exceeded navigation
capacity of Yingshang Ship Lock. In May 2012, more than 600 vessels had to keep
waiting to pass through the Ship Lock, which caused traffic jam on the waterway.
As Anhui Shaying River Channel Improvement Project to national standard Class IV
is going on, insufficient throughput capacity of Yingshang Ship Lock will become more
and more significant (Throughput at Yingshang Ship Lock is estimated to be 14.5 million
tons in 2020, and 21.5 million tons in 2030). Therefore, it is very urgent to expand
Yingshang Ship Lock by increasing 2nd waterway ship lock, so as to meet the cargo
transportation demand through Shaying River, and the increasing cargo transportation
demand due to social-economic development at inland regions of Shaying River.
As an expansion to Yingshang Ship Lock, construction of 2nd waterway ship lock
will eliminate traffic bottle neck at existing Yingshang Ship Lock. It will meet cargo
transportation demands through Shaying River and development of large vessels, attain

3. Engineering Overview and Analysis
3.1 Conditions of Existing Ship Lock
3.1.1 Yingshang Ship Lock Overview
Yingshang Ship Lock (single waterway lock) is located at right side of the Regulating
Lock, connecting to approach bridge of the Regulating Lock at east side, and crossing
flood control bank at west side. Construction work of the Ship Lock commenced in
September 2005 and completed in 2008, and it has been opened to navigation upon
completion. The Ship Lock is in size of 180×12×3m (Length×Width×Minimum water
depth above sill). It is designed for Class IV channel and 500-ton vessel, with a design
annual throughput capacity of 6 million Tons. Its lock chamber is pre-stressed reinforced
concrete dock structure. Its upper and tail bays are integral reinforced concrete base slab.
Central water supply system is applied. Guide wall in upper and lower streams is
reinforced concrete counterfort wall structure. Mooring piers at upper and lower streams
are rubble concrete piers structure.
Approach channel: approach channels in upper and lower streams were constructed
through excavation. Its bottom width in straight section is 35m, and extended width in
curve section is 47m, minimum bending radius is 350m. Approach channel in upper
stream is 1318.89m long, while that in the lower stream 1821.94m. Excavated side slope
of approach channel is at gradient of 1:3~4. Bottom elevation of approach channel in
upper stream is 16.4m, while that in lower stream is 14.5m.
Anchorage: No anchorage has been
constructed for Yingshang Ship Lock.
Anchorage is included in the Shaying
River Channel Improvement Project. Up to
December 2013, construction works for
upper anchorage at Yingshang Ship Lock
has not started, while excavation of
earthworks for construction of lower
anchorage is under way.
Figure 3-1 Mooring piers in approach channel at lower stream
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock

Before planning of expansion, it was intended to build anchorage area at left bank of
approach channel in lower stream. 4 mooring piers were built in size of 1.0×1.0×2m.
As the location of these mooring piers is in conflict with the location of 2nd
waterway ship lock, these mooring piers will have to be dismantled. See Figure 3-1 for
current status of the mooring piers.
Water consumption volume: On the basis of actual opening times (16 times) per day
in 2013, water level difference between upper and lower streams (water depth above sill
being 3m for sufficient consideration), and lock chamber area (180×12=2160m2), the
maximum discharge flow in low flow period is calculated to be approximately
103680m3/d, equivalent to a flow of 1.2m3/s.
Road bridge over the ship lock and connecting road is designed as Class II road in
flat and light rolling area. Design load is that of Class I road. Road bed is 15m wide, and
road pavement 12m. Road bridge is 15m wide, the same as that of road bed. Clearance
height of navigation opening is 7m. Retreated bank is constructed in compliance with
Class II standard.
Construction works of Yingshang Ship Lock and road bridge over the Ship Lock
commenced in September 2005, and completed in June 2008. The total actual investment
is 140,585,900RMB, including 6,902,000RMB investment in environment protection
which accounts for 4.91% of the total investment.
3.1.2 Types of Transport Cargoes
Through statistics data on cargoes volume through the lock after completion of
Yingshang Ship Lock, it is found that cargoes mainly include coal, mineral, construction
material, foodstuff, fertilizer, and few chemical products. The chemical products are urea
fertilizer, compound fertilizer, Methanol, Hydrogen Peroxide mainly produced at Linquan
chemical plants. Normally, such chemical products will be shipped through Cihuaixinhe
River below Jieshou to the channel of Huaihe River. Only in case of navigation suspension
on Cihuaixinhe River, such chemical products will be transported through Yingshang Ship
Lock to Huaihe River.
3.1.3 Environment protection
As mentioned in the “Examination and Acceptance Sheet on Environment Protection
upon Completion of Yingshang Ship Lock on Shaying River in Yingshang County (July
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
31
2012)”, two environmental protection measures raised in the Environment Impact
Assessment were adjusted: no oily wastewater treatment station has been provided for the
project, the vessel’s oily wastewater will be treated by oil water separator mounted on the
vessel; upon treatment through septic tank, domestic wastewater will be discharged into
wastewater collection basin (volume being around 13.5m3), and not be discharged to the
outside, but used for green belt sprinkling within management area. Except the said two
points, other measures prescribed in the Environment Impact Assessment have been
basically implemented.
Based on the letter on examination and acceptance comments on Environment
Protection upon Completion of Shaying River Yingshang Ship Lock as issued by
Environmental Protection Department of Anhui Province, together with the examination
and acceptance report, it is concluded that the environmental protection measures raised in
the Environment Impact Assessment have been implemented in the construction works of
Yingshang Ship Lock and overpass road bridge.
3.1.4 Existing Environmental Issues
Through field investigation, it is found that when vessels stop and wait for lock in
main navigation channel of upper and lower streams, and when water flow increases at
water discharge time of the Regulating Lock, the vessels cause impact to safety of the
Regulating Lock. Currently in day time, the Ship Lock will mainly use loudspeaker to
broadcast safety rules for vessels through the lock, even though the broadcasting is in
short time and in controlled frequency, it still causes impact to the residents in the vicinity
of lock chamber.
3.1.5 “Using new method to improve the old one” environment protection measure
After completion of this Project, through efficiency of vessels will be improved, the
waiting time for lock shortened, and the number of waiting vessels decreased, so that it
will reduce vessel’s impact to safety of the Regulating Lock. After completion of this
Project, management system of the Ship Lock will be improved, safety rules will be
repeatedly displayed on LED screen, and usually loudspeaker will not be used for
broadcasting safety rules anymore, so that it will reduce noise impact to ambient
environment.

3.3 Alternative analysis
3.3.1 Alternative proposal comparison for location of 2nd waterway ship lock
Taking account of structure constraints in vicinity of Yingshang Ship Lock, plane
layout of ship lock, overpass road bridge, bank retreat and such other factors, two
alternative proposals have been produced for east location and west location of 2nd
waterway ship lock. The east location proposal is such that the 2nd waterway ship lock
would be constructed between the single waterway ship lock and the Regulating Lock, for
which no retreat of flood control bank and no resettlement of residential houses will be
required; The west location proposal is such that the 2nd waterway ship lock would be
constructed between the single waterway ship lock and the diversion bank, for which
2km-long west (right) flood control bank will have to be retreated to the right side for
60~80m, residential community and commercial premise in 71700m2 along S102
provincial highway will have to be dismantled and relocated, it would be a very tough task
to resettle the residents. Without involvement in sensitive factors of environment
protection, the west location proposal not only requires retreat of flood control bank to the
right side for 60~80m, but also requires more earthworks, dismantling and relocation, land
acquisition and investment than the east location proposal. After overall consideration, it is
to recommend the east location proposal, the same as that recommended in the feasibility
study report.
3.3.2 Selection of size of lock chamber
On the basis of design vessel type and operation proposal, two size proposals are
raised in the feasibility study for comparison and selection: Proposal I: 200×23×4(m)
(Length×Width×Water depth above sill); Proposal II: 230×23×4(m)
(Length×Width×Water depth above sill).
3.3.2.1 Proposal I (200m)
Proposal I: 200×23×4(m) (Length×Width×Water depth above sill). The 2nd
waterway ship lock would be located at the east of the single waterway ship lock. The
longitudinal axis of the two lock chamber will be in parallel with a spacing of 62m. For
connection of guide walls of these two lock, edge line of head bay of 2nd waterway ship
lock in upper stream will exceed 10m to that of the single waterway ship lock.
3.3.2.2 Proposal II (230m)
Proposal II: 230×23×4(m) (Length×Width×Water depth above sill). The 2nd
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
38
waterway ship lock would be located at the east of the single waterway ship lock. The
longitudinal axis of the two lock chamber will be in parallel with a spacing of 62m. The
basic layouts of Proposal I and II are almost the same. The difference is such that edge line
of head bay of 2nd waterway ship lock in upper stream will be the same as that of single
waterway ship lock, but tail bay will be moved to lower stream for 40m, edge line of tail
bay will exceed the guide wall of single waterway ship lock, straight section of approach
channel in lower stream will be reduced by 40m.

demand, without environment constraint. When comparing to Proposal II generally,
Proposal I has advantages: less work quantities, less construction difficulty, minor impact
to normal navigation through single waterway ship lock during construction, less
investment, less wastewater and solid waste produced during construction, and less impact
to ecological environment. Therefore Proposal I with lock chamber size of 200×23×4(m)
(Length×Width×Water depth above sill) is recommended, the same as that recommended
in feasibility study report.
3.3.3 Alternative proposal comparison for road bridge over Yingshang Ship Lock
3.3.3.1 Status of existing bridge
Existing road bridge (old bridge) over Yingshang Ship Lock is in total length of
419.02m. Its superstructure adopts 11×20m pre-stressed cast-in-situ concrete box
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
42
girder+(38+55+38)m pre-stressed concrete box girder with varied section+4×20m
pre-stressed hollow concrete slab. The (38+55+38)m pre-stressed concrete box girder with
varied section is used to span over the retreated bank at the west side, and the 20m
pre-stressed hollow concrete slab is used to span over the existing ship lock.
As for substructure of the old bridge, 0# abutment adopts U-shape abutment
connecting with bored pile foundation; 17# abutment adopts rib plate abutment connecting
with coping and with bored pile foundation below; bridge piers adopt 2nd column piers
connecting with bored pile foundation. Capping beam adopts large cantilever pre-stressed
concrete structure.
3.3.3.2 Standard for bridge improvement
Due to constraint of old bridge and Regulating Lock, the bridge and its plane layout
will be arranged along alignment of old bridge, centerline of proposed improvement
bridge will be the same as that of existing road and bridge. In accordance with general
layout of 2nd waterway ship lock, this lock is located at east side 62m away from single
waterway ship lock (within the 17th span of old bridge), and being around 90m away from
the end of approach bridge (2nd arch bridge with two spans) of Regulating Lock. Bridge
improvement is designed as per secondary urban trunk road: design speed of 30km/h, road
boundary of 15m width, concrete payment, Class IV navigation channel, maximum
navigable water level of 27.13m (10-year recurrence interval). The bridge upon
improvement will be in total length of 465.21m. 50m pre-stressed continuous box girder
with varied section will be adopted for main span over 2nd waterway ship lock, 27m
adopted for connection with the 14th span of old bridge. Proposal I is that the navigable
clearance height shall be not less than 7m; Proposal II is that the navigable clearance
height shall be not less than 6m.
3.3.3.3 Proposal I (clearance height of 7m)
If navigable clearance height of 2nd waterway ship lock is 7m, it is necessary to
adjust profile of road, dismantle and reconstruct approach bridge (to be lifted up for
around 3.7m), improve bridge (all decks to be lifted up for 1m) over Regulating Lock.
Upon lifting up and improvement, elevation of bridge over Regulating Lock will be transit
to top elevation of existing bank through approach bridge at south side.
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
43
3.3.3.4 Proposal II (clearance height of 6m)
If navigable clearance height of the 2nd waterway ship lock is 6m, after redesign of
profile of road, the end elevation of approach bridge (double arch bridge with two spans)
of Regulating Lock will be around 33.71m (lifting up for around 2.5m), and it is necessary
to improve bridge over Regulating Lock.
Improvement proposal for bridge over Regulating Lock: partial deck system will be
improved in length of 35m and lift up for 0~500mm.
3.3.3.5 Alternative proposal comparison
In view of work quantities, different navigable clearance heights of the 2nd waterway
ship lock requires different work quantities in improvement of Regulating Lock and its
approach bridge. It is obvious that Proposal I requires more work quantities and more cost
than Proposal II.
In view of environment protection, environment impact caused by the bridge
locations under Proposal I and Proposal II is similar. However, as Proposal I requires more
work quantities, construction personnel will increase accordingly, who will produce more
domestic wastewater and waste than that under Proposal II; besides, construction
wastewater and solid waste produced from construction activity will also be more than
that under Proposal II; Proposal I requires more raw materials than Proposal II, as
Proposal II saves raw materials.
Through overall comparison in view of work quantities and environment impact,
Proposal II is recommended, the same as that recommended in the feasibility study report.
3.4 The 2nd
ship lock
3.4.1 Plane layout
In the proposal (east location proposal) recommended in the feasibility study report,
the 2nd waterway ship lock in size of 200×23×4m (Length×Width×Water depth above sill)
will be located between single waterway ship lock and Regulating Lock, for which it is not
necessary to make retreat of flood control bank. Longitudinal axis of two ship locks will
be in parallel with spacing of 62m. S102 road bridge will run over lock chamber. Edge line
of head bay of the 2nd waterway ship lock will be on the same line with that of single
waterway ship lock in upper stream. Upper and tail bay, as well as lock chamber of the
2nd waterway ship lock will be arranged symmetrically with those of single waterway
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
44
ship lock. All lengths of upper and tail bays in flow direction are 30m, and length in
section of lock chamber is 200m.
3.4.2 Design elevation
Elevation of various components of the ship lock is as below:
(1) Head bay (2) Lock chamber (3) Tail bay
Top elevation of gate:
29.70m
Top elevation of wall: 28.3m
Top elevation of gate: 28.90m
Top elevation of wall: 30.0m Elevation of base slab: 12.40m Top elevation of wall: 30.0m
Top elevation of sill: 15.30m
Elevation of bottom sill: 12.40m
3.4.3 Water consumption volume
Taking account of the estimated one-direction throughput of 14.57 million tons at
2040, average daily water consumption in ship lock is calculated to be 9.73 (m3/s),
average water consumption for one time through is 21367m3, and average water
consumption for one ton cargo is 6.47m3.
3.4.4 Hydraulic buildings
(1) Lock chamber
Lock chamber of the 2nd
waterway ship lock in effective size of 200×23×4m
(Length×Width×Water depth above sill) will adopt integral reinforced concrete structure in
reverse “Π” shape. In line with water filling and empting layout, a long culvert with cross
section (Width×Height) of 4.0×3.0m will be provided in side wall of lock chamber. To
reduce work quantities of lock chamber, centerline of the long culvert will be smoothly
and gradually moved inward for 1m at the head and end. Bottom elevation of base slab in
lock chamber is 9.6m. Base slab in wall is 2.8m thick. Bottom of base slab at both sides of
culvert will be lifted up for 1.3m. The base slab is in total width of 38.6m. Thickness of

3.11 Construction Organization and Construction Proposal
3.11.1 Construction Organization
General construction layout shall be made as compact and rational as possible on the
basis of design, so that all technical index and economic index therein will be advanced
and rationalized. Good and rational construction layout shall be worked out in the key
points, such as division of worksites, traffic and transportation organization, various
temporary works, stock of construction equipments, machineries & tools, as well as
drainage on worksites. The division of worksites shall be suitable for work process. In
principle, the worksites shall be divided on the basis of functional units, so that no
interference will arise among various specialities, work processes and work categories,
which will be beneficial for management and construction.
(1) Transportation condition
Shaying River is navigable for 500t class vessel all year. 102 provincial highway runs
above Regulating Lock and the upper head of single waterway ship lock, with connection
to many national highway and expressway in China. Cement, reinforcement bar, sand,
stone, equipments and other cargoes can be delivered to worksite through Shaying River
or 102 provincial highway. The transportation condition is superior.
(2) Water and power supply
Water for concrete mixing and curing may be supplied from the nearest point of
Shaying River. T connection may be made to 10KV power grid at front gate of ship lock
management office for power supply.
(3) Construction materials
There are many sand pits along Shaying River, therefore sand are available for
purchase in the nearby. Hailuo Cement Factory is operating in Bengbu city at lower stream
of ship lock, and quarries are operating in Huainan and Huaiyuan. Cement and
stones/aggregates can be shipped to quay near worksite and transported to the worksite by
trucks. Magang (Group) Holding Co., Ltd. in Anhui Province produces various kinds of
wires and cables which are available for purchase. Therefore, no sand pit or quarry will be
set up for this project.
(4) Production and living compound
Production and living compound is located at unoccupied area at right side of
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
59
diversion bank of Regulating Lock, covering land of around 0.92hm2. This land is flooded
land and tidal flat. Upon completion of construction works, the production and living
compound will be duly cleared up, leveled for green belt, and integrated into ship lock
management area.
3.11.2 Construction process
Construction works are mainly consisted of lock chamber, upper and tail bay,
approach channels and road bridge over ship lock and such other auxiliary works. The
main work items include cofferdam, foundation pit support, foundation pit dewatering,
earthworks (excavation and backfilling for foundation pit, excavation for navigation
channel), reinforced concrete, casting for bored piles, fabrication and installation of metal
components, installation of electro-mechanical equipments, and bridges.
(1) Cofferdam
2nd waterway ship lock for expansion is located between single waterway ship lock
and Regulating Lock. During construction, the previous flood discharge section will not be
affected, and all waters coming from upper stream will be discharged through the existing
flood discharge facilities. However, it is necessary to provide cofferdam at upper and
lower stream of foundation pit, so as to retain water.
① Cofferdam for lock head
Design of cofferdam: the water-retaining cofferdam for upper and tail bays shall be in
the structure of two-row steel sheet piles filled with clay in the spacing. Steel sheet pile
will adopt Lassen new V-shape steel sheet pile. The spacing between interior and exterior
steel sheet piles is 2m. Steel top beam will be provided on top of steel sheet piles. H-shape
steel waling will be provided at interior side. Regarding cofferdam for head bay, its design
retaining water level is 27.13m, its top elevation is 28.13m, and filling volume between
spacing of two rows is 1567m3. Regarding cofferdam for tail bay, its design retaining
water level is 23.78m, its top elevation is 24.78m, and filling volume between spacing of
two rows is 952m3.
Construction process of cofferdam: steel sheet pile will be driven by vibrating
hammer. Before pile driving, it is necessary to provide two guide beams along two pieces
of steel sheet pile. Then it is to start drive steel sheet piles from the side of wing wall of
single waterway ship lock to the bank in groups. Upon completion of pile driving, the
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
60
spacing between two rows will be filled with clay, which should be tamped and compacted
by frog tamper. Top beam and interior steel waling will be welded H-shape steel.
② Cofferdam for construction of mooring piers
Design of cofferdam: construction of mooring piers will be arranged to carry out in
low flow period. During construction, it is necessary to provide and maintain
water-retaining cofferdam by adopting earth-bag cofferdam. Top width of cofferdam is
1.5m. Both interior and exterior side slopes will be at gradient of 1:1. Bagged earth is
required in volume of 7053*2m3, and impermeable geo-membrane is required in area of
3242*2m2.
Construction process: construction of earth-bag cofferdam is a normal one. Earth will
be put into bag by hands. When water level is low, earth bag will be stacked by hand.
Geo-membrane will be laid at exterior side to avoid permeability. Exterior slop toe will
extend to the outside for 2m, and bagged earth will be stacked over it. The cofferdam will
be dismantled by excavator, and load onto dump truck for hauling to disposal area.
(2) Foundation pit support
Cast-in-place pile support will be used for foundation pit support of head bay
(including guide wall in upper stream), lock chamber, tail bay (including guide wall in
lower stream).
(3) Foundation pit dewatering
Excavation bottom elevations of foundation pit for head bay, lock chamber and tail
bay are 8.8m, 9.5m, 7.8m respectively. Excavation depth is 20~22m, which get involved
in water bearing layer. Due to effect of water level in upper stream, permeability
coefficient is within range of 1.50×10-4~1.64×10-5cm/s.
Cutoff wall will be used as main water interception method for foundation pit,
supported by light well-point dewatering. Foundation pit will be enclosed by high pressure
jet-grouted cutoff wall. Axis length of wall top is 674m. Boring shall start from the point
around 20m away from ground. Top elevation of high pressure jet-grouted cutoff wall is
around 19m. It is required that wall bottom should extend into relative impermeable layer
⑦ layer for not less than 1.0m. Drainage ditch will be provided on upper side slope and
stage of side slope, so as to allow for open drainage.
High pressure jet-grouted cutoff wall is required in area of 10089m2, bored hole for
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
61
11486m, grouting for 8666m; 5 light well points and each point include 30 pieces of well
pipe; dewatering shifts are calculated to be around 3600.
High pressure jet-grouted cutoff wall will be constructed by high pressure
jet-grouting machine. Boring and grouting will be conducted in sequence. Before
construction, it is necessary to make test on productive well points, so as to determine
construction parameters. During high pressure jet-grouting, it is necessary to frequently
check and adjust high pressure water pump, pressure of low pressure mud pump, grouting
flow, wind pressure and wind flow of air compressor, rotary speed and lifting speed of
bore machine, as well as actual grouting consumption volume.
(4) Construction of Earthworks
Construction Sequence
Cofferdam construction, foundation pit excavation and backfilling for head bay;
cofferdam construction, foundation pit excavation and backfilling for tail bay; excavation
and backfilling for guide wall and approach channels in upper and lower streams in the
third year.
Construction Method:
1) Excavation of earthworks: ① For foundation pit excavation, 2m3 backhoe
excavator will work with 12~15T dump truck. For protective layer of foundation plane,
and for local excavations which would be difficult for excavator, as well as for side slope
treatment, such excavation works will be carried out by hand, and the spoil will be hauled
by two rubber wheel barrow.
② For excavation above water for approach channels in upper and lower streams,
2m3 backhoe excavator will work with 12~15T dump truck. 1m
3 clamshell dredger ship
is proposed for excavation in water. Spoil will be transported by 100t dredge barge to the
bank, and then loaded by excavator to dump truck, and hauled to disposal area.
2) Backfilling of earthworks: ① Excavated earth will be used for backfilling of
foundation pit. Such earth will be loaded by 2.0m3 backhoe excavator, and hauled by 12~
15T dump truck to filling surface. For narrow area in width of less than 3.0m adjacent to
retaining wall, backfilling will be carried out by hand layer by layer, tamped and
compacted by frog tamper or by hand. Upper part (filling width≥3m) will be leveled and
compacted by 74KW bulldozer.
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
62
② Backfilling for buildings will start after concrete or mortar for masonry reached
70% of its strength. Regarding backfilling for outline foundation pit of buildings, it mainly
use 74KW bulldozer for spreading earth in thickness of around 25cm, and for compacting.
At contact areas (width less than 3.5m) with buildings, it should be tamped and compacted
by frog tamper or by hand, spreading earth is in thickness of 15~20cm. Mechanical
construction will be adopted for all backfilling of banks, and 74KW bulldozer will be used
for leveling and compacting.
3) Working Process of Clamshell Dredger
Clamshell Dredger in swing type uses its boom and steel wires to suspend bucket.
The bucket lowers down at its own gravity to bottom of water for grabbing mud. Then
start the wire winch, close and hoist the bucket through pulley on top of boom, swing to
the designated point (or dredge barge) and release mud. The boom swings back to
dredging point and continue dredging operation. Dredging process recycles in this manner.
Clamshell Dredger is mainly used to grab clay, silt, pumice stone, and desirably fine sand
and silty sand.
Working process of clamshell dredger: dredger grabs bite of mud from channel under
excavation, and releases the bite to dredge barge. The dredge barge transports mud to the
water near edge of offshore beach, opens its bottom (body) to release mud, which will be
hauled by truck to disposal area. Maximum grabbing depth of 2m3 dredger is 20m.
Full-load draught of 60~100m3 dredge barge is 2.0m.
(5) Concrete Casting
Concrete casting for this Project will be in volume of 83,000m3, among which
58,500m3 will be for lock chamber, upper and tail bay, and the remaining for mooring
piers, guide piers, upper and lower aprons and other structures.
After completion of foundation treatment, and removal of construction platform,
concrete casting may start for lock chamber, upper and tail bay. Base slab of head bay in
thickness of 3.5m is the maximum block of base slab, requiring around 2780m3concrete,
for which casting will continue for 2 days in 3 shifts.
For concrete casting of base slab, steel formwork will be mainly used as side
formwork, wooden formwork for curvature positions of pier wall, wing wall, as well as
upper beam and column, bamboo glue formwork for plane face of pier wall. For mass
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
63
concrete in lock chamber, upper and tail bay, mixed concrete will be delivered by truck,
conveyed to casting face through vacuum negative pressure trough, cast block by block
and layer by layer, vibrated manually layer by layer by immersed vibrator. For concrete of
side wall and upper structure, concrete will be pumped to casting face, so as to solve issue
of horizontal and vertical delivery.
All concrete will be centrally mixed in HZS90 type concrete mixing station.
Materials will be fed mechanically. Raw materials will be loaded from stockpile to
aggregate bin by 4.0m3 loader. Horizontal and vertical delivery to each casting face will be
completed by truck and HBT60 concrete pump together with pipe.
(6) Bridge Construction
Substructure of bridge will be constructed in normal method. Pile foundation for
bridge will be rotary drilled and bored pile.
For box girder in superstructure of bridge, concrete will be cast in site with full space
support. Hollow slab in superstructure will be precast in advance, then hoisted and
installed.
3.11.3 Construction Program
Construction program arrangement principle: as for interference construction
between bridge improvement and main structure of ship lock, firstly hydraulic structures
(approach channels in upper and lower streams, lock head, lock chamber), then auxiliary
buildings/structures (management building, substation, water supply and drainage system,
etc). Construction for hydraulic structures (approach channels in upper and lower streams,
main structure of ship lock) will be organized in various stages and various sections.
Construction duration: 30 months in total.

3.12 Engineering Analysis
3.12.1 Pollution Intensity Analysis for Construction Duration of Ship Lock
3.12.1.1 Pollution Chain
Environment pollutions in construction duration can be divided into water, acoustic,
air and solid waste. See Table 3-5 for pollution chain in construction duration of the Ship
Lock Project:
Figure 3-5 Illustration of Construction Process and Pollution Chain
3.12.1.2 Water Environment Pollution Source Intensity Analysis
Water pollution sources during construction include: domestic wastewater discharged
by construction personnel; increasing suspended sediment in water during excavation;
residual water from drying and dewatering for mud delivered from water area to

temporary spoil storage area; oily pollution caused by construction machines. Main
pollutants are COD, NH3-N, SS and oil.
(1) Domestic wastewater pollution intensity source prediction
Domestic pollution source is calculated in accordance with the following equation:
Wi=ACi
Where Wi——Discharge volume (kg/year) of pollutant in i.
A——Man-day (Man-day/year) in construction area
Through analog calculation on the basis of statistical data for normal towns in the
local area, it is predicted that domestic water consumption of construction personnel is
100L/person/day, wastewater production is estimated at coefficient of 0.8. Concentration
of COD is 300mg/L, and concentration of NH3-N is 40mg/L. Construction duration for
Shaying River Channel Yingshang 2nd Waterway Ship Lock is 30 months (assumed to be
900 working days), average construction personnel is around 200, then 180,000 man-day
will be required for the Project. In construction peak period, construction personnel will be
around 300. Discharge volume of domestic waste pollutant by construction personnel is
indicated in Table 3-10. Domestic wastewater volume produced during construction will
be 14400m3, including 4.32t COD and 0.576t NH3-N.
Table 3-10 Domestic wastewater produced during construction
May-day Domestic wastewater
volume COD volume NH3-N volume
180,000 man-day 14400m3 4.32t 0.576t
200 man-day 16m3/ d 4.8kg/d 0.64kg/d
300 man-day 24 m3/ d 7.2kg/d 0.96kg/d
(2) SS pollution source intensity prediction
During excavation in water, foundation pit dewatering, boring well dewatering,
washing operation at sand and aggregate stockyard, washing operation for construction
machines and vehicles, a lot of wastewater with SS content will be produced. It will cause
impact to ambient water environment, and the river flow will become turbid as increasing
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
70
of SS concentration. The SS concentration during construction period will be within the
range of around 80~160mg/L.
Foundation in water should be constructed in low flow period. In case of cofferdam
adopted for foundation work in water, upon completion of construction works, the waste
arising from removal of filling earth inside cofferdam and bagged earth, as well as rock
mud and silt produced from construction works, shall be transported to and collectively
stored at disposal area. They are not allowed to be dumped into water body. When
grouting pile is used as foundation pit support, bored pile is used for construction of bridge,
the masonry work or casting work will be conducted on site. As wastewater produced
from the inside of cofferdam, and mud produced from grouting pile have relatively high
content of SS, they need to go through sediment in sediment tank, and then the sediment
will be cleared up, transported to and collectively stored at disposal area.
3.12.1.3 Atmospheric environment pollution source intensity analysis
Main impacts caused by construction works to atmospheric environment: dust from
ground leveling and old bridge dismantling, and dust blown by wind during excavation,
transportation and handling of construction materials, and stacking of materials, will
increase concentration of suspended particles in ambient atmosphere, and pollution to
local area will be increased. Monitoring on worksites of same nature indicates that dust
concentration in vicinity of worksites can reach 1.5~30mg/m3. The dust volume from road
is correlated to dust thickness on ground.
Emission of construction equipments (such as vehicles, diesel engine of vessels) is
another important pollution source, which include pollutants of SO2, CO and NO2.
Normally diesel engine of vessels produces NO2 at rate of 1.66kg/kWh, and SO2 at rate of
2.31g/kWh. As illustrated by 8T vehicle, pollutant discharge volume from normal
construction vehicle with diesel engine is indicated in Table 3-11. Such kind of
atmospheric pollution source is relatively scattered, its intensity is difficult to identify, and
it will comes to an end upon completion of construction works.

3.12.1.4 Acoustic environment pollution source intensity analysis
(1) Construction area
During construction, noise of construction vehicles and machines will cause adverse
impact to ambient acoustic environment. Construction machines mainly include dump
truck, excavator, bulldozer, loader, grader, hamper, concrete mixer, pile driving machine,
paver, roller, etc. Most of these construction machines are categorized as burst non-steady
noise source. During operation, noise source of these machines can reach as high as
78~86dB(A); noise of clamshell dredger and dredge barge for excavation in water is
around 80~100dB(A). As there is certain distance between construction area and
residential communities on both sides, together with barrier of banks at both sides, no
much harm will be caused to environment if construction time is rationally arranged.
However, it is necessary to strengthen protection, so as to avoid harm to nearby residents
and construction personnel on site.
(2) Spoil transportation route
This assessment gives particular attention to the impact caused to ambient sensitive
points by truck running on spoil transportation route during construction. Actual total spoil
volume for this Project will be 1,351,800m3, which will be transported to disposal area.
Excavation time for lock chamber and lock head will be 4 months, excavation time for
approach channels 15 months, which will not be overlapped with each other. Excavation
and spoil volume for lock chamber and lock head is 158,600m3, which will be transported
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
72
to 1# Disposal Area through sensitive point of Xinhe Village (South of bridge). Excavation
time is 4 months (assuming 30 days/month for calculation), each heavy-duty truck will
carry 20T (equal to 5m3)/trip, then it required 265 trips, there are 8 working hours per day,
truck flow will be 33 trucks/hour, and round trip truck flow will be 66 trucks/hour.
Excavation volume for approach channels will be 1,191,500m3, among which 653,400m3
spoil will be transported to 1# Disposal Area through No. 1 route, truck flow will be 50
trucks/hour, and round trip truck flow will be 100 trucks/hour; the other 162,000m3 spoil
will be transported to 3# Disposal Area through No. 2 route, truck flow will be 33
trucks/hour, and round trip truck flow will be 66 trucks/hour. Heavy duty trucks shall run
slowly within speed limit of 35Km/h. In analogy to traffic noise on road project within
operation period, emission source intensity of single heavy duty truck is calculated in
accordance with the following equation:
Heavy duty truck: Lw,l =22.0+36.32lgVl + ∆L Longitudinal slope
Where: Lwl――means average radiation noise level of heavy duty truck
∆L Longitudinal slope——when being less than 3%, the correction will be 0.
Emission source intensity (7.5m) of single heavy duty truck is calculated to be 77.9dB(A).

from disposal area will be disposed at a corner of disposal area, 2400m3 waste from
dismantling will be used as filling materials of road bed, and all the remaining
1,351,800m3 spoil will be transported to and disposed at disposal area. The actual total
spoil is 1,351,800m3.
Assuming domestic waste of construction personnel as 1.0kg/person/day, taking
account of the number of construction personnel and construction duration, domestic
waste during construction is calculated to be 180t in total.
3.12.2 Pollution source analysis for bridge improvement period
3.12.2.1 Construction sequence of bridge
Construction sequence of bridge: To dismantle partial hollow slabs, piers, pile
foundation of old bridge, dismantle approach bridge of Regulating Lock, reconstruct road
bridge over ship lock and approach bridge of Regulating Lock. See Figure 3-6 and Figure

3.12.2.2 Water pollution source
Water pollution sources during construction mainly include: 1) oil pollutant escaped,
spilled, dripped, or leaked from construction machines, oily wastewater produced from
rainwater running over construction machines in open air; 2) domestic wastewater and
waste in living compound causing pollution to water body; 3) When bored pile is used for
construction of bridge, masonry work or casting work will be conducted on site. As mud
produced from grouting pile has relatively high content of SS, they will go through
sediment in sediment tank, and then the sediment will be cleared up, transported to
disposal area.
Bridge improvement will be completed in short period, and wastewater is in small
volume and will come to an end upon completion of construction works. Main water
pollutants are COD, BOD, SS and oil. Repair of construction machines should be
conducted in the maintenance workshop as much as possible. As water for washing during
repair has oily pollutant, it will go through oil separation treatment prior to recycling use.
As for wastewater produced by construction personnel during construction, it is necessary
to provide facilities for sediment, oil separation, harmless treatment, as well as makeshift
lavatory. It is required to regularly clear up these facilities, and transport wastewater to
municipal wastewater treatment plant for treatment, or provide to nearby farmland or
green belt for use.

3.12.2.3 Atmospheric environment pollution source
Main atmospheric environment pollutant is dust, including dust from old bridge
dismantling, dust from transportation, handling and mixing of materials, and dust blown
by wind during stacking of materials. When wind velocity is high or the vehicle speed is
relatively fast, dust pollution will become worse. In addition, construction machines will
produce fume emission during operation. Such kind of atmospheric pollution source is
relatively scattered, its intensity is difficult to identify, and it will comes to an end upon
completion of construction works.
3.12.2.4 Noise pollution source
During construction, noise sources mainly are construction machines (such as
excavator, loader, pile driving machine, paver, roller, etc). Most of these construction
machines are categorized as burst non-steady noise source. During operation, noise source
of these machines can reach as high as 78~86dB(A). Such burst non-steady noise will
cause adverse impact to the nearby residents and construction personnel.
3.12.2.5 Solid waste
Solid waste mainly includes construction waste from dismantling of bridge, domestic
waste of construction personnel. It is necessary to collect and duly remove domestic waste
of construction personnel. Dismantled hollow slab, pier and pile foundation will be used
for reconstruction of bridge whenever possible. If not qualified for reuse, dismantling
waste will be crushed and used as filling material of road bed within management area.
Dismantling waste shall not be randomly disposed at river channel, river bank or any other
places.
3.12.3 Pollution source intensity analysis for operation period of ship lock
3.12.3.1 Management module in operation period
In operation period, unified management will be adopted for 2nd waterway ship lock
and single waterway ship lock. The operation body is Ship Lock Management Station,
which is under direct management of Anhui Provincial Port & Shipping Construction
Investment Group Co. Ltd (APPSCIG) in aspect of administration and business.
(1) Navigation days per year
Navigation days per year are assumed to be 350 days/year.

76
(2) Average through lock times per day
Average one-direction through lock times per day is assumed to be 36 times/day.
(3) Quota of staff
For the newly-built 2nd waterway ship lock, the work will be divided into 3 shifts,
each shift is 8 hours, the quota of staff for each shift is 6 persons. The lock will operate for
22 hours per day. The quota of staff is 28 persons.
3.12.3.2 Water environment pollution source intensity analysis
Water pollution sources in operation period are mainly domestic wastewater
produced by working staff in the lock and working staff on vessels, as well as oil pollutant
produced by vessels. Main pollutants are COD, NH3-N and oil.
1. Pollution source intensity analysis for working staff in the ship lock
In operation period, 28 staffs will work for the Ship Lock Management Station. On
the basis of “Residential Community Wastewater Quality Standard”, actual wastewater
production volume by working staff in the ship lock is assumed to be 100L/Person/Day,
concentration of COD is assumed to be 300mg/L, concentration of NH3-N is assumed to
be 40mg/L. Wastewater, COD and NH3-N production volume per year will be 980t/a,
0.294t/a and 0.039t/a respectively.

2. Vessel domestic pollution source intensity prediction
As prescribed in the “Administrative Regulations of People’s Republic of China on
Prevention and Control of Environmental Pollution of Inland Waters Caused by Ships,
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
77
Decree of Ministry of Communications (2005) No. 11”, vessels shall be equipped with
treatment device or storage containers matching with wastewater volume in accordance
with specifications. Discharge of domestic wastewater that cannot meet discharge
standards is forbidden in inland water. Time for passing through the ship lock is
comparatively short (the ship lock will open for 36 times per day, every opening will take
36.6min, the ship lock will be open for 22 hour per day). In this assessment, the number of
personnel is assumed to be 30 persons, average wastewater per person is assumed to be
100L/d, the wastewater production volume will be 3.0m3/d. Assumed that discharge
volume is 50% of production volume, then the discharge volume will be 1.5m3/d.
Discharge of vessel domestic wastewater shall comply with the “Effluent Standard for
Pollutants from Ship”, minor wastewater meeting the said effluent standard will cause
limited impact on water body, for which this assessment will not make further assessment.
It is recommended that port and channel management authority should enhance
management. It is forbidden for vessels to discharge domestic wastewater when normally
passing through the ship lock.
3. Vessel oily pollutant volume prediction
To improve technical level of inland water transportation vessels, optimize structure
of such vessels, ensure transportation safety of vessels, prevent and treat vessel’s pollution
to water area, the Ministry of Transport promulgated “Administration Rule on Vessel
Standardization for Inland Water Transportation” on October 11, 2001, which came into
force since December 1st, 2001. As prescribed in the aforesaid Administration rule, motor
ships hanging oar engines longer than 20 meters is forbidden to engage in inland waterway
transportation. The Ministry of Transport promulgated “Development Outline of National
Standardization of Inland Waterway Transportation Vessels” on February 16th, 2006. This
Outline defined the general objective for national standardization of inland waterway
transportation vessels, and stipulated that motor ships hanging oar engines will be phased
out. As motor ships hanging oar engines are not allowed for inland transportation, it
effectively reduces oil leakage and other water pollution accidents, decreases noise along
waterway, improves efficiency of ship lock, lowers down safety accidents. In general, it
results in very good social-economic benefits.
As prescribed in the 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 Communications (2005) No. 11, effluent pollutants of vessels shall
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
78
comply with relevant national and local standards and requirements in this regard. In the
event that pollutant of vessel cannot comply with such standards and requirements, it is
required to designate a qualified and competent pollutant receiving entity for receiving and
treatment, and no random discharge is allowed. It is also stipulated that in the event of
ballasted water, washing water, bilge oil water, residual oil, oily wastewater and such other
residual pollutants, it is necessary to make report to and obtain approval from maritime
management authority prior to discharging in accordance with relevant regulations. As
regulated by port and channel management authority, it is forbidden to discharge bilge oil
water into water body when passing through ship lock. Therefore, not much impact will be
caused to water body when vessels pass through ship lock normally.
3.12.3.3 Atmospheric environment pollution source intensity analysis
During operation, main atmospheric environment pollutants are waste emission,
including the SO2, NO2 contained emission from operating engines of vessels, and slight
oily fume from living facility within Ship Lock Management Station. Vessels’ waiting
time for ship lock is around 0.6 hour, during which the engines are almost in idle. Waste
emission is produced when vessels navigate through upper and lower approach channels
(in total length of 1310m). In accordance with calculation method for vessel emission as
recommended by Lloyd's Register of Shipping, every ton of fuel will generate 7.2kg NO2
emission, and 10kg SO2 emission. Fuel consumption for vessel in inland waterway is
assumed to be 3.71kg/kt·km.
On the basis of cargo volume passing through Shaying River Yingshang Ship Lock, it
is predicted that cargo volume will reach 14.50 million tons in 2020, and 21.50 million
tons in 2030. Operation days per year is assumed to be 350 days, NO2 emission from
vessels passing through the ship lock in 2020 will be 0.14kg/d (49.0kg/a), and SO2 will be
0.20kg/d (70.4kg/a). In Fuyang area, prevailing wind direction in one year is east wind,
average wind velocity in one year is 2.8m/s. The surrounding land is flat, pollution source
is mobile, and ambient air has strong dilution capacity. Therefore, slight impact will be
caused by emission of atmospheric environment pollutants to local air environment during
operation. In addition, with development of science and technology, promotion of
advanced technology, inland waterway transportation vessels will be renovated for better
performance in environment protection and energy saving, thus emission of atmospheric
environment pollutants will become less and less in the future.
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock

Only a few staffs work in the Ship Lock Management Station. Clean fuel-liquefied
gas will be used. There is no boiler. Therefore, its waste emission can be neglected.
3.12.3.4 Acoustic environment pollution source intensity analysis
Noise sources of vessel passing through the ship gate are mainly noise of motor
(including emission noise) and horn. During operation, noise in distance of 5m away from
noise source can reach 80~90dB(A). Noise creating equipments are continuous and steady
noise source. It will cause adverse impact to residents at both sides. Pre-measurement
indicates that it can meet Class 2 standard as set in “Environmental Quality Standard for
Noise” (GB3096-2008) when at 20m to boundary line of navigation channel in day time
and at 50m in night time. The sensitive point-Jiangxinzhou residential community is
located at 36m away from boundary line of approach channel, and right bank of Ying
River stands as a barrier, therefore slight impact will be caused to this residential
community. With development of science and technology, promotion of advanced
technology, inland waterway transportation vessels will be renovated for better
performance in environment protection and energy saving, thus noise along the waterway
will be reduced in the future.
3.12.3.5 Solid waste prediction
Solid wastes during operation period are mainly domestic waste produced by ship
lock management personnel and working staffs on vessel. Domestic waste production
volume is assumed to be 1.0kg/person/day. 9800kg/a solid waste will be produced by the
28 staffs (in 350d), which will be collectively treated and disposed by City Appearance,
Environment and Sanitation Authority.
As definitely prescribed in the Administrative Regulations of People’s Republic of
China on Prevention and Control of Environmental Pollution of Inland Waters Caused by
Ships, it is forbidden to discharge waste from vessel to inland water; waste on vessel must
be received and treated by qualified and competent entity. This assessment will not
calculate domestic waste produced by working staffs on vessel. Waste storage container
with cover shall be provided on vessel, which shall be impermeable and shall have no
spillover. Or alternatively, bags can be used for waste storage. Waste shall be classified,
collected and stored, so as to meet demand of vessel waste storage during navigation. It is
forbidden to use disposable foaming plastic tableware that cannot be degraded.

3.12.4 Investment and analysis on current pollution source of single waterway ship lock
Through field investigation, it is found that the main pollution source of Shaying
River Yingshang Junction is the pollutant discharged by the ship lock management station,
which have 20 working staffs at present.
3.12.4.1 Source of Water Pollution
On the basis of “Residential Community Wastewater Quality Standard”, actual
wastewater production volume by working staff in the ship lock is assumed to be
100L/Person/Day, concentration of COD is assumed to be 300mg/L, concentration of
NH3-N is assumed to be 40mg/L. Wastewater, COD and NH3-N production volume will be
2000L/d, 0.60kg/d, 0.08kg/d respectively. In compliance with the letter regarding
examination and acceptance comment on environment protection upon completion of
Shaying River Yingshang Ship Lock Project, the wastewater of the ship lock management
station will be treated through septic tank, and then used for green works, and not
discharged to the outside.
3.12.4.2 Atmospheric environment pollution source
Some working staffs of the ship lock management station take food in the dining hall.
Clean energy of liquefied gas and power is used in kitchen. Oil mist will be treated by
kitchen ventilator. Therefore the waste gas can be neglected.
3.12.4.3 Solid waste
Solid wastes of the ship lock management station are mainly domestic waste
produced by ship lock management personnel. Domestic waste production volume is
assumed to be 1.0kg/person/day. 7.0t/a domestic waste will be produced by the 20 staffs,
which will be collectively treated and disposed by City Appearance, Environment and
Sanitation Authority.
3.12.5 Summary of pollutants in ship lock

4. Investigation and Evaluation on the Status of Environmental
Quality
4.1Natural Environment
4.1.1 Geographical Position
Yingshang 2nd
Ship Lock Project is located at the Yingshang hub of the Shaying
River Channel, between the Yingshang Regulating Lock and the existing Yingshang Ship
Lock.
The shipping history of Shaying River could be traced to the year of 506 BC, and the
channel has been renovated for many times. The Shaying River flows towards the
Yingshang County when it comes to the Yingshang hub, taking on an outlook of a large
curve, where people made a curve cut-off to the Shaying River in the 1950s of the last
century. In 1982 the regulating lock was built at the part of curve cut-off but without built
matching navigation facilities. In 2008, the last grade ship lock of the lower reaches of the
Shaying River---Yingshang Navigation Lock, was completed and opened to navigation.
After the year of 2008, the Shaying River Channel restored the navigation entirely, with
the completion and operation of the Yingshang Ship Lock, Fuyang Ship Lock, and
Genglou Ship Lock.
4.1.2 Climate and Meteorology
The Works area lies in a region transiting from warm temperate zone to subtropical
zone, belonging to sub-humid continental climate of the warm temperature zone.
Changing with the fluence of monsoon and relief feature, the climate appears arid rainless
in Winter and Spring while stuffy rainy in Summer and Autumn. The mean temperature of
air through out the year is 15.1℃, with the extreme maximum and the extreme minimum
are respectively 41.2℃ and -22.8℃. The frost-free season of the area is about 220 days
on average.
4.1.3 Topography Survey of the Region
The project area is located at the Huaibei Plain. The 2nd
ship lock’s main building
expansion site is situated in a flat terrain with a ground elevation of 23.0~25.0m. The
micro-relief sheet of the approach channel are the flood plain and the riverbed of the
Shaying River, with a ground elevation of 23.0~25.0m, an elevation of about 20.0m in its
upper reaches, and an elevation of about 15.7m in the lower reaches.
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
83
The reconstructed expansion site of the bridge stage appears a flat terrain, with the
flood plain of the Shaying River as its micro-relief sheet and a ground elevation of
25.26~25.51m, the elevation becoming higher gradually when getting near the dam, and
the elevation of the embankment filling 0.5~6.0m higher than the original ground. For the
details of the original raw topography of the Works’ surroundings, please refer to Figure
4-1.
4.1.4Geology of the Works
The project area of the extension is in the stratum exposed within the scope of
exploration depth, mainly containing about over the depth of 16m the alluvial materials of
the reiver bed and flood plain of the Shaying River, belonging to Pleistocene Series of
Quaternary System (Q4al) , while below the depth of 16m, the river alluvial materials of
Holocene Series of Quaternary System (Q3al) .

4.1.5Water Resource Conditions
The Shaying River enjoys rich water resources, mainly coming from rainfall and
other anabranches. According to the feasibility study report, the ship lock has an average
water consumption of 9.73m3/s one day. It has an average lockage time of 36.6 minutes, a
quota of 21367 m3 as its one time irrigation water volume of the ship lock, and an
emptying time of the lock chamber of about 7 minutes. The emptying time of the ship lock
is just a temporary process, while during the majority of the time there is still water in the
approach channel, and even during the emptying process the water flow velocity in the
approach channel (with a bottom breadth of 40 meters, and a minimum water depth of 2.5
meters) is relatively small. The main stem flows without changes after the construction of
the ship lock project. According to the design of the ship lock, the filling time of the lock
chamber is calculated as 7 minutes one time, the discharge will be about 50.9m3/s and the
current velocity only 0.5m/s, therefore the influence on the water consumption of the
Yingshang Lock by the ship lock construction is very small. However, taking into account
the increase in the volume of cargo traffic passing through the ship lock as well as the
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
85
increase in the time of opening the lock and emptying the water, the storage capacity at the
lock will be consumed. Because the water level is mainly controlled by the regulatory lock,
it should be kept in accordance with the hydraulic department to optimize the use of the
water resources.
4.1.6Groundwater
The groundwater in the project area belongs to the type of unconfined groundwater,
mainly occurring in the Pleistocene Series of Quaternary System (Q4al) and the deeper
Holocene Series of Quaternary System (Q3al). During the survey, the bury of groundwater
of actual measurement in the ship lock project area is 1.4~3.0m and the corresponding
groundwater elevation is ▽23.14~▽22.43, therefore the deep laer groundwater does not
have much effect on the ship lock project. During the survey, the bury of groundwater of
actual measurement in the approach channel project area is 1.50~4.70m and the
corresponding groundwater elevation is▽ 23.15~ 23.87m, therefore the deep laer
groundwater does not have much effect on the ship lock project. The elevations of the
Shaying River, in the upper reaches and the lower reaches are 24.3m and 18.1m. The
groundwater is mainly supplied by river and wet precipitation. According to relevant
materials, the groundwater type is HCO3--Cl--Ca2+
, which is non-corrosive to reinforced
concrete.
4.1.7Earthquake
According to Seismic Peak Ground Acceleration Zonation Map of China (1:4 000
000) (GB 18306-2001), the seismic peak ground acceleration of the site of the extension
project is 0.05g.
According to Code for Seismic Design of Buildings (GB 50011-2001), the soil type
of the site is judged as mid soft soil, the ground category as category II, located at the
unfavorable district for seismic buildings, with a cycle of design feature of 0.35 g.
4.2Social Environment Yingshang County lies in the northwest of Anhui Province, where the Huai River
meets the Ying River. The county occupies a land area of 1859 square kilometers,
accounting for 1.4% of Anhui Province, among which 103 thousand hectares are
cultivated land. The county is flat and open, belonging to Huaibei Plain and Huai River
Region, sloping from northwest down to southeast, with the elevation ranges from 40 to
38 m. The soils are mainly Shajiang black soil, with stable soil texture, proper pH value

on April 26 ~ April 27, please refer to Chart 4-3.
4.5.2 Status Evaluation of Surface Water Environment
(1)Evaluation Criteria
According to the function planning of water environment of Anhui province and the
standard confirmation issued by Fuyang Municipal Environmental Protection Bureau, the
water quality of Shaying Rive surface water is pursuant to the water quality standard of
category IV in Environmental Quality Standard for Surface Water (GB3838-2002) (SS
implementing the standard extreme for dry corp stipulated in Standards for Irrigation
Water Quality (GB5084-2005)).
(2) Evaluation Factors
Combining with the monitoring situation of the surface water, except for DO, 8
monitoring elements including H, COD, SS, BOD5, total phosphorus (TP), total nitrogen
(TN), petroleum and fecal coliform bacteria (FCB), except fr DO, are selected as the
evaluation factors of the surface water in the current evaluation.
(3) Evaluation Method
Standard index evaluating method of HJ/T2.3-93 Guidelines for Environmental
Impact Assessment is adopted to make evaluation to the water environment status.
(4)Evaluation Results
According to the single index calculation results (see Chart 4-4): monitoring factors
including pH, DO, COD, BOD5, petroleum and fecal coliform bacteria (FCB) of sections
reach the Category IV standard requirements of Environmental Quality Standard for
Surface Water (GB3838-2002); SS meets the standard extreme value requirement for dry
corp kind stipulated in Standards for Irrigation Water Quality (GB5084-2005); total
phosphorus (TP) and total nitrogen (TN) of the three sections all exceed the standards, TN
exceeding by a 3.05 times, and TP exceeding by a 0.62 times. The status of the surface
water quality of the district of Yingshang Ship Lock of Shaying River does not meet the
standard requirements Category IV of Environmental Quality Standard for Surface Water
(GH3838-2002).
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
91
It is indicated in the investigation that, TN of the 10 sections all exceed the criteria
when conducting monitoring to the water quality status of the stage from the junction of
Henan-Anhui on the Shaying River Channel 100m to the lower reaches to Yingshang
County, with an exceeding time of 3.04~4.15; TP exceeds in 8 sections, with an exceeding
time of 0.03~0.65 (data drawn from Report of Environment Impact of The Realignment
Project of Anhui Shaying River Channel), therefore the main cause of TN and TP
exceeding criteria at the stage of the Yingshang County of the Shaying River is the
pollutants carried in the upper reaches. Furthermore, there are cultivated lands deployed
near the ship lock of Yingshang of Shangying River, therefore it is suggested that
non-point source pollution from agriculture in the rural area may be one of the reasons that
caused TN and TP exceeding the criteria.

Pursuant to Confirmation Letter on the Applicable Environmental Impact Assessment
Standards for the Shaying River Yingshang 2nd Waterway Ship Lock Project (Fu Huan
Xing Shen Han [2013]27) issued by Fuyang Municipal Environmental Protection Bureau,
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
97
4a category criteria of Environmental Quality Standard for Noise (GB3096-2008) are
applied to the scope 30m within the red lines of the both sides of the channel and the
criteria of category 2 of the standard hereof is applied to the other scope, for monitoring
the acoustical environment.
(2)Evaluation Results
Please refer to Chart 4-7 for the monitoring and evaluation results of the status of the
sensitive sites and the environmental quality of the approach channel boundary, and refer
to Chart 4-8 for the results of vehicles volumes.
From the monitoring and evaluation results of the status of the sensitive sites and the
environmental quality of the approach channel boundary (Chart 4-10) we can see that, the
noise status values at the sensitive site N1 (M1) are 51.6~53.2dB(A) in daytime and
44.3~45.0dB(A) in the nighttime, meeting the standard requirements of Category II of
Environmental Quality Standard for Noise (GB3096-2008); the channel boundary noise of
N2 and N3 are 52.0~52.5dB(A) in the day time and 48.2~48.9dB(A) in the nighttime,
conforming to the extreme limits stipulated in Emission Standard for Industrial Enterprises
Noise at Boundary (GB12348-2008); the noise monitoring point of the road bridge N4
appears 72.4~73.8dB(A) in the daytime and 54.6~54.8dB(A) in the nighttime, with a
degree of 3.8~2.4dB(A) exceeding the standards in the daytime, both the two days’
exceeding of monitoring noise caused by the noises sent by the diesel vehicles like trucks
passing through the road bridge. The monitoring data of November 30~December 1 show
that, the monitoring value of the status of the five sensitive sites (M3~M7) with serial no.
of N5~N8 and N11 are 39.1~60.0dB(A) in the daytime, and 2.4~48.6dB(A) in the
nighttime, satisfying the standard requirement of Category II of Environmental Quality
Standard for Noise (GB3096-2008); sensitive sites with serial no. of N5 and N6 show a
relatively higher monitoring noise value correspondingly because they are nearer to the
road bridge ane be affected by it more. The sensitive site N9 (M8) appears
53.5~56.3dB(A) in daytime and 50.2~50.4dB(A) in the nighttime, with the values of the
nighttime exceeding the standard by 0.2~0.4dB(A). The monitoring point is located at the
east side of the left dam, with S102 going through the gate of the family area of the
regulating lock office, carrying a big traffic volume, and the sensitive site is mainly
affected by the traffic noise of S102, and large and middle vehicles volume are similar
with that of the daytime and there there dog biking from family area when making
monitoring, therefore above causes lead a little exceeding criteria in the nighttime.

4.7.3Monitoring of Attenuation Sections of Ships of Approach Channel
Select the middle part of the approach channel in the lowe reaches, relatively open
and without human interferences to set the ship noise attenuation sections, and the
monitoring data are included in Chart 4-9. For relationship between noise attenuation and
distance please refer to Figure 4-4.
Figure 4-4 Section of Noise Attenuation of Ships of Approach Channel
According to the statistics results we can conclude that:
①As the space and distance increase, attenuation of noise value is relative obviously.
It meets the criteria of the Category II out of the both sides of the approach channel both in
the daytime and in the nighttime.
②It could be shown in the monitoring statistics results that, it meets the principle of
noise attenuates gradually as the distance increases, displaying a maximum noise value at
the place of 40 m in distance in the synchronous monitoring value, with 59.2dB (A) as the
noise in the daytime, 54.5dB (A) in the nighttime; and a minimum noise value at the place
of 20 m, with 38.5dB (A) as the noise in the daytime, 36.5dB (A) in the nighttime
③It could be learned in the data listed in Chart 4-9 that, for the sections of noise
attenuation of the traffic of the ships of the approach channel of 40~60m, 60~80m, 80~
120m, and 120~200m, the attenuation values in the daytime are respectively 2.6, 2.3,10.3
and 5.5dB(A), and those in the nighttime are respectively3.5, 2.5, 5.3, 6.7dB(A). The
monitoring noise values in the daytime and in the nighttime are relatively large around
80m, and the place of 80 m of the monitoring points is located at the top of the approach
channel, therefore it is seen that the dam of the approach channel has a good obstruction
function for the noise spreading, working as a natural noise barrier.

4.7.4Continuous Noise Monitoring of 24 Hours of Traffic Noises
The continuous monitoring of 24 hours is conducted by selecting the place of the
right top over the lock chamber and in the north side of the road bridge. Meanwhile the
traffic volume are recorded, for the monitoring results please refer to Chart 4-10 and
Figure 4-5 and Figure 4-6.
Figure 4-5 Noise Changes in 24 Hours
Figure 4-6 Changes of Vehicles Volume in 24 Hours
From Chart 4-13 and Figure 4-5-6 it can be drawn that:
①At the continuous monitoring point of 24 hours, the traffic noises are in portion
with the traffic volumes, and the noise increase with the increase of the traffic volume.
②
The continuous monitoring point of 24 hours of noise difference of between the
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
100
daytime and the nighttime is small mainly because the traffic volume of the large and
middle vehicles which contribute most to the noise are basically the same in daytime and
in the nighttime.
③From the the continuous monitoring results comparison of the traffic noise and
vehicles volume and Chart 4-13, we learned that: the statistic results shows large vehicle
types account for 14.8% of the whole day traffic volume, middle vehicles 15.88%, and
small vehicles 69.28%, while in nighttime their portion are respectively 33.9%,46.1%,
and 20.0%. It is seen that at present small vehicles in operating are the most, then the
middle, and the large vehicles are the lest, while in the nighttime the middle vehicles are
more than large and small vehicles.
4.8Sediment Environmental Quality Evaluation
4.8.1 Status Monitoring
On April 24, 2013, Fuyang Environmental Monitoring Station made a sampling once
near the Yingshang Ship Lock of Shaying River, the sampling method conducted
according to relevant environment monitoring technical specifications. The monitoring
factors are 8 items including pH, Cu, Pb, Zn, Hg, As, Cr, and Ni, and the monitoring is
referred to in Figure 2. Furthermore, for data of TN and TP, please refer to the status
monitoring data in the evaluation of environment impact of the realignment project of
Anhui Shaying River Channel.
4.8.2Evaluation Results
(1) Evaluation Criteria
Pursuant to Confirmation Letter on the Applicable Environmental Impact Assessment
Standards for the Shaying River Yingshang 2nd Waterway Ship Lock Project (Fu Huan
Xing Shen Han [2013]27) issued by Fuyang Municipal Environmental Protection Bureau,
the sediment of the channel is referred to the criteria of Grade II of Environmental Quality
Standard for Soils (GB15618-1995). Additionally, the current evaluation meanwhile refer
to the control criteria of Control Standards for Pollutants in Sludges from Agricultural Use
(GB4284-84).
(2)Evaluation Method and Results
The status of the sediment is evaluated by using single factor contaminant index, and
it is shown by the evaluation results (Chart 4-11) that: the contents of all kinds of heavy
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
101
metal pollutants in the sediment of the Ying River Channel of the Shagying River are
smaller than the criteria of Grade II of Environmental Quality Standard for Soils
(GB15618-1995), and meanwhile smaller than the control criteria of Control Standards for
Pollutants in Sludges from Agricultural Use (GB4284-84), and could be used in spoil area
for biological recovery construction after piling and wind dried naturally, without the plant
growth and human health affected by the heavy metal contents. Spoil quality basically
does no bring noise harming plant and environment.
(3) N and S concentrations in Sediment
According to the analysis results of the sample mud (surface layer of 5cm) of from
the Shayinag River surface, on the N and S content, conducted by Fuyang Environmental
Monitoring Station and included in Report of Environment Impact of The Realignment
Project of Anhui Shaying River Channel, the N and S contents range respectively within
0.2~0.7mg/kg and 0.15~0.56mg/kg, with 0.45mg/k and 0.26mg/kg as their average
value respectively. The monitoring data of the Sediment in the district of the Yingshang
County of the Shaying River Channel shows that, the TN content of the sediment of the
river channel is 0.655mg/kg, a little higher than the average level; and TP content is
0.151mg/kg, a little lower than the average level. TN and TP contents of the surface of the
sediment of the Shaying River are very low, therefore, basically it will not affect the whole
water quality because of little organic nutrients like N, P and others caused by the disturbs
when making digging operating in the sediment digging project.

5 Environmental Impact Assessment and Prevention and Control
Measures
5.1 Social environment impact
5.1.1 Transportation
(1) Highway bridge
During the construction period of this Project, due to highway bridge reconstruction,
the temporary traffic interruption will have adverse impact to the local transportation. This
bridge is an important passage to get in and out of Yingshang County, so the impacts to
vehicles and pedestrians shall be respectively considered.
In recent years, with the development of social economy, Yingshang successively
built multiple bridges across Ying River, including Ying River Bridge No.2, Ying River
Bridge No.3, Ying River Bridge No.4 and Ying River Bridge No.5, which significantly
improves the urban transportation in the east-west direction and extends the urban
development space. Due to the bridge density has a sharp increase, during the bridge
reconstruction period, this Project will not set temporary bridge or other temporary traffic
facilities; vehicles can make the round via other bridges; for example, they can make the
round from Shunhe Road in the right side of Yingshang Ship Lock, →Guangzhong
Avenue and → Yingxi Road in the left side of check gate, with 5km of detour mileage.
This bridge is an important passage to get in and out of Yingshang, and there is
school nearby, and it is inconvenient for the pedestrians, residents and students nearby to
interrupt the pedestrian access, so it is advised to retain the pedestrian access function on
the bridge, and the construction period shall be arranged at summer vacation or winter
vacation when there are less students nearby; it shall remind the pedestrians to pass there
safely and cautiously during the construction period.
Ship lock highway bridge traffic interruption will have adverse impact to the local
transportation and the local government and transport section shall complete the
coordination and guidance work.
(2)Existing Yingshang Ship Lock
During the 2nd waterway ship lock construction, the existing Yingshang Ship Lock
will continue for navigation, and they will maintain the existing ship lock navigation
capacity by taking steel plate cofferdam and foundation pit supporting; therefore, it will
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
103
not have significant impact on the navigation ships.
5.1.2Population health protection
1. Construction area clean-up
At the early stage of construction period, carry out the cleaning and disinfection work
of the construction camps, level the site, use phenol drug use motor sprayer to disinfect the
toilets and garbage heap on the construction camp, and clean the solid waste.
During the construction period, carry out deratization, mosquito eradication and fly
eradication activities in the construction range to reduce infectious vector and cut the
pathophoresis route. Especially the deratization work shall be strengthened, which shall be
carried out once a quarter. Use miehailin aerosol to exterminate flies, twice a year.
2. Food hygiene management and supervision
Regular food and hygiene inspection and supervision to the construction area must be
conducted; the kitchen staff must have hygiene license to do their job, the ones who have
access to food must have “health certificate”; if any food poisoning, effective control
measures must be taken to prevent source of the disease from expansion.
3. Health and epidemic prevention
The construction workers must have physical examination before they get into the
site, and if there is any new-entry infectious disease, the patient must be quarantined to cut
off the route of transmission; in the second year, carry out physical examination to 20% of
construction workers to know their health conditions and prevent prevalence of diseases.
Set medical aid post in the place with relatively concentrated construction workers,
equipped with commonly used drugs to carry out simple treatment and first aid of
occupational injury.
The constructor and engineering management department in the construction area
shall have a health and epidemic prevention duty officer to manage the health and
epidemic prevention in the range and carry out the food and hygiene publicity and
education to the construction worker to improve their consciousness to prevent diseases.
5.1.3 External workers
The adverse impact to social environment in the construction period is also reflected
in external construction workers’ impact to the society. The increase of external
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
104
construction workers whose lifestyle has major difference with the local residents, might
lead to conflict or theft; the public security has potential unstable elements.
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.
5.2 Ecological and Environmental Impact
5.2.1 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 ship lock main
works and approach channel excavation works, including water conservancy facilities land;
and temporary land occupation is mainly for construction machinery, site and spoil area;
(2) Mechanical work: its rolling compaction damages the aboveground vegetation
and 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;
5.2.2 Impact on vegetation
The impact of Yingshang 2nd waterway ship lock engineering on the vegetation
along is mainly reflected on two aspects: first, permanent land occupation reduces the
shrubby grassland area along the Shaying River and the landscaping vegetation area
within Administrative Office land occupation; second, the temporary land occupation of
excavation area in the construction period will damage the aboveground vegetation, and
its recovery requires a certain period of time; see Clause 5.1.1.5 for the impact analysis of
excavation area. In this section, we focus on the impact of permanent land occupation to
vegetation in the region.
According to field survey, the tree loss caused by engineering permanent land
occupation is mainly the plants cultivated by people in ship lock Administrative Office,
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
105
and it is advised to transplant the trees before the construction and then use them for
landscaping after the completion of works. This project’s impact to flood land shrubby
grassland mainly is reflected in the occupation of flood land due to approach channel
excavation, which reduces the flood land vegetation area and has a certain influence to the
ecological function and benefits in some areas.
The 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 ship lock engineering area and
greening compensation from the water department will make up for considerable biomass;
therefore, the vegetation destroyed by the 2nd waterway ship lock engineering will not
have influence to the abundance of species and ecological functions of the ecosystem near
the engineering.
5.2.3Impact on aquatic organism
(1) Impact on plankton
The spatial and temporal distribution and change in quantity of plankton are closely
related to the water transparency, and in the engineering construction period, approach
channel excavation 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. We can know by comparing with the actual works in the Dian
Lake dredging, 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; the grab-type dredger construction’s impact to water area
is way smaller than the cutter-suction dredger. Therefore, in the bottom sediment dredging
process, SS’s impact to the water quality of Shaying River is limited.
In general, compared to the evaluated water area, the influence range of the
construction is not very big, 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
Shaying River is minor.
(2) Impact on bentonic organism
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
106
Benthos is one of the important aquatic organism types in the aquatic ecosystem of
Shaying River water area, and the impact of environmental change to their survival is
rather obvious due to their low mobility; the most direct influence is the loss of benthos
caused by reduction of bottom sediment out of approach channel excavation. But in
general, the construction will only have a certain disturbance to the benthos in this area
during the excavation process, and with the gradual settlement of bottom sediment after
the construction, the benthos nearby will gradually return to the damaged habitat, and the
number of species and biomass will have a slow rebound process. Although the approach
channel excavation will lead to the reduction of benthos biomass, the species in the
riverway are all frequent species, and the impact is temporary; with the completion of
approach channel excavation, the bottom sediment is becoming stable, the survival
environment of benthos will be recovered. Therefore, the impact of approach channel
excavation to benthos is acceptable.
(3)Impact on fish
During the construction, the increase of sediment concentration and turbidity within a
scope caused by approach channel excavation and bottom sediment change caused by
washing will damage the habitats of plankton and benthos in the construction area to some
extent, and analyzing from the angle of food chain, will have certain influence to the fish
growth in the construction area. But from the previous analysis, we can see that the
impacts of approach channel excavation in this project are temporary and will not change
the ecological environment of plankton and benthos; therefore, reduction of fish baits
during the construction period has minor influence to fishery resources.
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. The approach channel excavation will damage
the fish habitat in certain range and will also drive the fishes far away from the
construction site. But generally, 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 approach channel excavation 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
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
107
site, feeding ground or wintering ground designated by fishery sector; therefore, this
project has no direct influence to spawning and reproduction of fishes.
5.2.4Agroecological Environmental Impact
(1)Land occupation’s impact on agroecological environmental
This project has 9.90hm2 of permanent land occupation, which is all used for
hydraulic structure; so there is no need to carry out cultivated land
requisition-compensation balance. The temporary land occupation is mainly spoil area
covering the area of 33.83hm2, which is currently cultivated land and will be used as
public greenbelt and construction land; this project will not occupy any farm land, and the
temporarily occupied land shall be leveled, afforested or ploughed after the completion. To
sum up, the temporary land occupation will temporarily make the absolute quantity of
cultivated land reduce, but will not change the land use structure in this area, and the
farming mode and climate conditions will not change; therefore, in general, it will not
have obvious influence to the local agriculture ecology.
(3) Impact on agricultural production
This project’s permanent land occupation does not include cultivated land; so there
will be no influence to agricultural production.
5.2.5 Rationality comprehensive analysis on spoil ground site selection
This assessment demonstrates the environmental rationality of spoil area from the
aspects of spoil area site selection principle, spoil volume, ambient environment and land
use master plan.
Spoil ground design. First, consider the construction soil demands of the towns of
Yingshang county, industrial parks of Yingshang county and Jiangxinzhou park, and try to
use the spoil to urban construction and reduce the land occupation area of the spoil area.
Second, consider the reinforcement of approach channel’s left embankment after the
completion of this project to digest some of the spoil. Third, set the temporary spoil area.
Spoil ground site selection. Using the engineering feasibility study organization unit
1:10000 topographic map and on-site findings, with the comprehensive analysis to
landform, land occupation type and rationality to allocate and transport earthwork to meet
waste disposal area demand, set 3 spoil areas, where No.1 and No.2 spoil areas are located
at the behind of right embankment approach channel, and No.3 spoil area is located at the
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
108
north side of Xin’gang sand yard of left embankment of Shaying River channel. See
Figure 3-12 for the position of the spoil area. See Table 5-1 for environment rationality on
spoil area site selection.
The spoil area shall be nearby the excavation area, which can avoid the
inconvenience and pollution of long-distance transportation. The site for spoil area shall
have convenient transportation for future re-use. The soil in spoil area will be covered by
the solid and bottom sediment excavated during the construction process, and the soil use
mode will be temporarily changed; after the completion of the engineering, the area will
be leveled and planted with grass, trees or landscaping. The land use mode will have
temporary or permanent change, so there will be no hazard to human health.
The machinery noise, residual water drainage and stink from bottom sediment during
the construction period of the spoil area might have influence to the residents nearby;
based on the survey results, the nearest residential area from the spoil area is 50m away;
therefore, the pollutants in the spoil area have little influence to the residential area.
The spoil area land is planned to be green land and general farmland, without
occupying basic farmland and basic farmland protection areas; therefore, the spoil area
site selection shall conform to the Master Plan of Yingshang County Town (2008-2030)
and Land Utilization Master Plan of Yingshang County (2006-2020).
No.1 and No.2 spoil areas are cultivated land which belong to the collective land
and their users are local farmers. During this land requisition, the users
will receive the compensation in accordance with the young crops compensation standards
of Fuyang City. After the completion of construction, the land will be
leveled, rehabilitated and return back to the local farmers. No.3 spoil area
is flood land which belongs to state-owned land. Due to the village plants
crops on the land now, they also will be compensated for the loss of crop
in accordance with the standards of the Fuyang City. After the
end of construction, the land will be leveled and green.

5.2.6Ecological protection preventive and restorating measures
In order to maintain the ecological balance and protect the biodiversity within the
region, we take ecological protection preventive and restorating 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.
This project is now in the stage of feasibility study, and it is advised to re-plough or
green the spoil area and other temporarily occupied lands, including temporary excavation
area, construction camps and mixing station after the completion of the engineering
according to their functions. The occupied cultivated land will be restored as cultivated
land; for the occupied green land, uncultivated land and mud flat shall be leveled after
removing and cleaning the wastes and temporary structures, and take full use of the spoil
to restore vegetation by planting trees and grass. In addition, in the construction period,
the constructor shall abide by the principle of “optimal land utilization” and occupy as less
land as possible.
5.3Evaluation of impact on environmental air
5.3.1Prediction of impact on environmental air in construction period
In the construction process, the primary impacts to environmental air include fugitive
dust and stink from the temporary excavation area.
Fugitive dust. The fugitive dust in this project mainly comes from foundation pit
excavation, stock yard exploitation, spoil stacking and vehicle transportation, and the main
pollutant is TSP. The pollution from fugitive dust in engineering to the environmental air
is temporary and local and will be gone after the completion of construction.
Sediment odor. There is polluted bottom sediment containing humic organism in the
excavation area, and when it is disturbed or stacked on the ground, there will be repugnant
substances (including ammonia and hydrogen sulfide) releasing in a non-organized
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
112
manner, which will influence the ambient environmental air quality. According to related
documents, the pollution of Shaying River’s bottom sediment is very small, and it rarely
stinks. The stink intensity is about level 1~2 with about 20m influence scope, and when
there is wind, the sphere of influence in downwind direction will be slightly greater.
According to the excavation area determined in project feasibility study research report
and field investigation, the residential areas nearby are all 50m away, and the stink from
the bottom sediment will not have obvious influence to the residents near this area.
5.3.2 Air control measures in construction period
(1) 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 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 earthwork transportation 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 site. Water the earthwork road for transportation to
avoid fugitive dust.
C. Take effective measures in the construction site, including covering, solidification,
greening and watering. The fugitive dust from 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 and other weathers. it is not allowed to carry out
earthwork backfill, transportation and other construction works might have the pollution
of fugitive dust.
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
113
G. The vegetation of temporarily occupied land shall be recovered to prevent water
and soil loss.
(2) Stink pollution control measures
A. During design, the selection of temporary spoil area shall avoid villages, and from
the aspect of site survey, the temporary spoil area is 50m or more away from villages,
which effectively avoids the influence of sediment odor 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 spoil area, and timely carry out
ecological recovery treatment;
(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.
5.3.3 Prediction and measures of impact on environmental air in operation period
In operation period, the exhaust gas pollutants are mainly from the fuel oil exhaust
gas generated from the operation of marine power plant, including CO, NO2, SO2, in the
way of linear emission along the shipping lane; there are good air diffusion conditions in
the region, so the air environment quality will not degenerate. In the expansion project
area, the air environment quality in the operation period shall meet the requirements for
Class 2 area in Ambient air quality standard (GB3095-2012).
There are not so many working personnels in the ship lock Administrative Office,
where uses liquefied gas, a clean fuel, and has no boiler, producing less exhaust gas; it is
advised that the mess hall of the Administrative Office shall install smoke purifier.
5.4Water Environmental Impact Evaluation
5.4.1 Water pollution impact during construction period
5.4.1.1 Domestic sewage in construction camps
According to the engineering analysis in Chapter III, the discharge value of domestic
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
114
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 Shaying River
surface water and have little impact to the water quality. But due to the the out of limits of
TN and TP in the water of Shaying River channel, it is advised to rent residences as
construction camps and set seepage-proofing latrine pits in the construction site, regularly
clean them, and strictly prohibit the random discharge of domestic sewage to improve the
water quality of Shaying River channel and reduce load. For construction site, collect the
other domestic sewage for watering and dust suppression. Besides, this project does not
involve any groundwater source field. Therefore, the domestic sewage produced in the
construction period of this project has small influence to the surface water nearby and little
influence to groundwater.
5.4.1.2Bridge construction’s impact on water environment
This project will retrofit the across-gate highway and spillway approach bridge. The
bridge dismantling waste residues are mainly bricks and concrete waste residues and
cannot be dumped at will; it is suggested to use them for the base course of construction
access road and administrative zone road. Use drilling cast-in-place pile for the
construction of bridge pier, and the reconstructed bridge during the construction period are
mainly in the dry land and there is no bridge pier in water, so drilling will not have
influence to the water quality of the river. However, the unbending discharge of boring
mud generated from foundation construction will occupy the Yingshang gate‘s spillway,
leading to the silting up of Shaying River and downstream channel of the construction site
in flood season; therefore, strictly prohibit to dump the mud to the channel or litter around
according to the provisions in the specifications of transport department and
environmental protection department. The boring mud, waste water and waste pulp
generated from the foundation construction of bridge in this project shall be subsided in
the settling pond and are strictly prohibited to be dumped to the channel or littered around
to avoid polluting the water body, elevate the riverbed or compress the cross-section of
river and silt up the channel; the stacking location shall be negotiated with the local water
conservation department and environmental protection department.
5.4.1.3Impact of suspended solids
The approach channel has some underwater dredging works, which use grab-type
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
115
dredger and berth. The grab-type dredger can cause the suspension and diffusion of local
water polluted bottom sediment; compared to other instances of channel underwater
dredging works, and the SS will have obvious increase in the water body within 100m
range; in general, the increment of SS concentration will be 80mg/L or above, and with the
range increasing, the influence will be gradually smaller; at 1km away from the
construction area, the SS concentration increment is as low as 4.13mg/L and the influence
of suspended sand is very little; with the completion of the construction, the influence will
be gone soon. Therefore, in the underwater dredging process in the construction period,
SS’s impact to the water quality of Shaying River is limited.
The hydraulic foundation engineering will use cofferdam and after the completion of
construction, the filled earth in the cofferdam, the waste soil after removing the bag
cofferdam and thick liquid and sludge during the construction shall be stacked on the spoil
ground in a collective manner; dumping in the water body is not allowed. The foundation
pit supporting uses cast-in-place pile for on-site masonry or pouring construction. In the
cofferdam, the production waste water and cast-in-place pile thick liquid mainly contain
high concentration of suspended matter SS and they shall be subsided in the settling pond
and then the sediment shall be transported and collectively stacked in the spoil ground.
5.4.1.4 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 oily wastewater in the
construction process; re-use the wastewater as a part of construction water after treating 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
pollution to surface water.
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
116
5.4.1.5 Bottom sediment environmental impact analysis
The Shaying River bottom sediment environment current situation evaluation results
indicate that the contents of heavy metal pollutants in the bottom sediment of the working
area are all lower than the Grade 2 standard in Environmental quality standard for soils
(GB15618-1995). After being stacked and air dried, this part of bottom sediment can also
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 begining 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 Yingshang 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.
5.4.1.6 Underwater earthwork residual water discharge’s impact analysis to water
environment
The approach channel excavation includes some underwater earthwork 53,980,000
m3, and the underwater part will use grab-type dredger for dredging construction and use
1m3 grab-type dredger to excavate, use 100t dredger pontoon to transport to temporary
wharf, use to load on excavator and transport to the spoil ground. The underwater
earthwork water content rate is high and according to related experience and documents,
the water content rate of grab-type dredger is about 65%. The drying process of the
underwater earthwork is designed to be: firstly, the underwater earthwork (water content
rate 65%) in the dredger pontoon shall be subsided on the dredger pontoon till the mud
and water have obvious separation; then directly drain the subsided water to the river
when the water content rate of the sediments are about 45%; then use excavator to load the
sediments to dump truck and transport to spoil ground, where they are naturally subsided
and evaporated; the collected residual water will be drained to collecting basin via the
preset ditch. In general, the water content rate of soil is 15%, the residual water quantity
can be produced in the spoil area based on calculations is 347,000m3.
The residual water quantity needs to be discharged in spoil area is 347,000m3. At the
early spoil stage, 90% of residual water has good water quality and about 10% of residual
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
117
water at later stage will be worse.
Set drainage ditch and settling pond in the spoil area. In addition, use gate chamber
type drainage exit for manual control of drainage rate and slurry concentration.
Due to the pollution of heavy metal, nitrogen and phosphorus to the Shaying River
bottom sediment is rather light, and the main pollutant in the residual water is suspended
matter; most of the suspended matter in residual water can be removed after natural
sediment and the settling pond, and the residual water subsided on ships can be directly
discharged into Ying River. If the subsiding time is not sufficient or the construction is
improper, it might cause the out of limits of suspended matter concentration; during the
construction process, it shall be strictly managed to allow the directly drained residual
water up to standard. The residual water subsided and collected in the spoil area can be
used for construction road spraying after gathered in the ditch.
At the later spoil stage, about 10% of residual water has out-of-limits SS value. The
residual water gone bad at later stage shall be calculated at 10%, which is about 34,700m3,
the excavation construction is usually arranged at the dry season; if the excavation project
duration is 100 days, the daily discharged quantity of residual water with poor water
quality is about 300m3. It can be naturally evaporated till there is only dry mud.

5.4.1.7Impact of removal of downstream approach channel breasting dolphin on
water environment
During the construction period, the existing breasting dolphin in the southeast side of
the downstream approach channel needs to be removed, and the removal of the concrete
structure will cause the temporary increase of SS content in the approach channel water;
therefore, in order to reduce the impact, the removal shall be arranged in dry season in a
safe construction mode; the removed cement blocks shall be timely cleared from the
approach channel to avoid accumulation in approach channel.
5.4.2Environmental 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.
1) Treatment of domestic sewage
The water pollutants in the domestic sewage produced in construction period are
mainly COD, BOD5, ammonia nitrogen and fecal coliform. It is advised to rent residences
as construction camps and set seepage-proofing latrine pits in the construction site,
regularly clean them, and strictly prohibit the random discharge of domestic sewage; other
domestic sewage shall be used for site watering.
2) 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 10m×4m×2m; and the pond body and inlet/outlet uses
brick masonry lining. After well treated, the wastewater will be used for construction road
watering or be drained outside; and the waste slag will be transported to the spoil ground.
3) 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 maintenance
area to collect the troubleshooting and washing wastewater, and set oil separator to treat
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
119
the oily wastewater. The construction machinery and vehicle overhaul washing wastewater
up to standard after treatment can be drained to the flood land nearby.
4) 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.
Residual water
Due to the contents of heavy metal, N and P in the Shaying River bottom sediment
are rather light, and the main pollutant in the residual water is suspended matters; most of
them can be removed after natural sediment. The residual water removing process starts
with standing in dredger pontoon for removal of about 20% of residual water; second, the
subsided water quantity is about 312,300 m3 at the early spoil stage in the spoil area, set
settling pond to collect residual water, and the daily residual water production quantity is
3132m3, calculated at 100 days of excavation project duration; the settling time is 3 hours
and it requires 390m3 of capacity; set 1 settling pond with capacity of 480m
3 in 2# and 3#
spoil areas with dimensions of 16m×10m×3m, considering any emergency. At the later
spoil stage, about 10% of residual water has out-of-limits SS value; the water quantity is
about 34,700m3, and the daily drained poor residual water quantity everyday is about
300m3. It can be naturally evaporated till there is only dry mud.
5.4.3Water pollution impact and protection measures 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 Chapter III, engineering analysis, the new domestic sewage output,
COD output and NH3-N output of ship lock Administrative Office in every year are
respectively 980t/a, 0.294t/a and 0.039t/a. Due to out-of-limits of TN and TP in Shaying
River channel, the domestic sewage must be used for greening of the station after the
treatment of bury-type integrated domestic sewage treatment devices. In addition, the
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
120
sewage treatment factory in Yingshang county has been built, so it is advised to closely
focus on Yingshang sewage pipe network; once the sewage drained by Administrative
Office can be incorporated into the urban pipe network, it shall be switched in this system.
The domestic sewage discharge value of lockage vessels shall be 1.5m3/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 Shaying 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 Shaying River water body environment.
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.
5.4.4 Coordination analysis of water use in operation period
According to Anhui Province Water Environment Function Division, the current
situation of Shaying River section in this project water function division is the agricultural
water region of Yingshang county, Fuyang and will be slated for industrial water.
According to Yingshang Gate Method of Dispatch and Use (2013), the normal storage
level of Yingshang gate is 24.0~24.5m (ancient Yellow River Elevation System), the
normal storage level can be turned up in the dry season and peak period. According to
2011 National Water Resources Census (Yingshang county) data, the total agricultural
water of Shaying River of Huaihe River drainage basin in 2011 is 212,000,000 m3, which
occupies 5.17% of 4,100,000,000 m3 of annual average volume of runoff. After the
completion of this project, the ship lock water consumption in operation period will
influence irrigation water. In particular, there is conflict between check gate catchwork
irrigation and ship lock operation water consumption in dry season. It is advised that in
special years, the Yingshang 2nd waterway ship lock operation department shall obey the
unified schedule of flood control and drought relief departments, timely close the gate,
inform the boat people in an effective way in advance, and strengthen the propaganda.

5.5 Acoustic Environmental Impact Evaluation
5.5.1 Acoustic environment in construction period
5.5.1 .1 Construction machinery noise impact
According to characteristics, size, site layout and construction mechanical equipment
selection of the project, the noisesgenerated in the construction activities of this project
mainly include construction material processing and construction machinery noise.
According to the engineering field monitoring in similar engineering, and see Table 5-2
for construction machinery noise; the sound level of primary construction machinery high
noise sound level equipment is 80~100dB(A).

1、Prediction mode
The machinery noise in construction period can be treated based on point acoustic
source; estimate the noise values in different distances from the acoustic source according
to sound attenuation degeneration modes of point acoustic source and synthetic acoustic
source; calculate the noise predicted value of sensitive spots at different distances from the
acoustic source by superimposing the noises and background values.
2、 Prediction outcomes
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.
(1)See Table 5-3 for the prediction of the noise contribution values of different distances from
the point acoustic sources.

(2)Predict the noise contribution values of different distances from superimposed acoutic
sources of multiple construction machineries.
The construction machineries of this project are mainly the excavators and
transportation vehicles used in earth excavation, excavator used in gate chamber
earthwork backfill, bulldozer and rammer compactor, concrete mixing station and steel &
wood processing factory used in the gate chamber structural works. There is a wide range
of construction machineries, there are different construction machineries in different
stages, and the quantity of construction machinery varies in a same construction phase,
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
123
which decides the randomness and disorder of construction noise. Take the construction
noise complexity, characteristics of region and stage of construction noise impact, and
then the construction site elevation difference impact into consideration. In this evaluation,
mainly analyze the situation that uses the fixed acoustic sources: Concrete mixing station
and steel & wood processing factory (in temporarily built house) in the ship lock structure
construction with great impact under unfavorable situation, and calculate the superimpose
noise sources of multiple construction machineries to the noise contribution values of
different distances (see Table 5-4) for the construction unit to take appropriate noise
pollution prevention and treatment measures based on the actual situation during the
construction.
(3)Predict the impact to sensitive spots from superimposed acoustic sources of multiple
construction machineries.
In calculating the impact of superimposition of construction machinery to acoustic
environment sensitive spot in the construction area, the relative distance refers to the
minimum distance from sensitive spot boundary to construction layout area boundary; in
this evaluation, use the minimum distance from sensitive spot boundary to construction
layout area boundary to replace the distance from sensitive spot to acoustic point. See
Table 5-5 for the sensitive spot acoustic environment predicted value.
3、Analysis on prediction outcomes
The construction area of this project is located at the right side levee of Ying River,
180m away from the approach channel right boundary, and the construction field’s
boundary is the expanded project land requisition scope. According to Emission Standard
of Environment Noise for Boundary of Construction Site (GB12523-2011), the noise limit
in day time is 70dB and 55dB in night time. From the predicting outcomes:
(1)Day time construction machineries, such as excavator, bulldozer, motor lorry,
concrete mixing station, the respective single noise can be up to standard in 31m at the
farthest extent, and in 175m in night time; after the superimposition of the construction
machineries, the up to standard distance in day time is 32m and up to standard distance in
night time is 180m.
(2)The steel & wood processing factory acoustic source grade reaches 100dB (A),
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
124
which is up to standard at 160m in day time, and 900m in night night; therefore, the
acoustic source of steel & wood processing factory meets the requirements in
GB12523-2011 in day time and exceeds the standard in night time. 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), thus the
steel & wood processing factory can be fully up to standard in day time and at 281m in
night time. The night-time construction will have bad influence to the residents nearby.
(3)You can see the impact of superimposition of construction machineries to
acoustic environment sensitive spots of the construction area from Table 5-5; from the
acoustic source superimposition prediction of steel & wood processing factory and
concrete mixing station, we can see that the noise value of 8 prediction points is
44.5~58.6dB (A) in day time and 39.2~54.0dB(A) in night time, and the construction
machinery noise contribution value is 29.3~53.5dB(A). The sensitive spots are up to
standard in day time and out of limits in night time; the out-of-limits quantity is
1.6~4.0dB(A); the out-of-limits prediction points are Jiangxinzhou Community - new
district (M1), Jiangxinzhou Community - Xinhe bridge northward (M2), Jiangxinzhou
Community - bridge southward I (M3) and ship lock Administrative Office neighborhood
(M8).
(4)The ship lock engineering 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.
5.5.1 .2The spoil transport route noise impact
1、 Prediction contents
The spoil in this project is mainly the excavation earthwork, the spoil area is set in
the left bank of Shaying River and east side of approach channel right bank, and there are
two existing routes for transportation; route 1: Ying River right bank access road - S102
highway bridge - approach channel left bank road - 1# spoil area, and the primary
sensitive spot involved in the route is Jiangxinzhou Community - Xinhe village; route 2:
upstream approach channel underwater earthwork - check gate highway bridge - Ying
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
125
River left bank (downstream) embankment - 3# spoil area, and the two sensitive spots
under influence are Zhan’gang Elementary School and Chen Tun. in addition, 2# spoil
area is mainly used for the downstream approach channel underwater earthwork
excavation spoil, and use ships to transport the spoil to temporary wharf and then use
automobile to transport to 2# spoil area. This evaluation mainly analyzes transportation
route 1 and transportation route 2. See Figure 3-12 for transportation route map.
2、 Prediction model
According to traffic flow and Technical Guidelines for Noise Impact Assessment -
Acoustic Environment (HJ2.4-2009), use highway traffic noise level calculation model
based on traffic volume (in different sections); the oversize vehicle model ratio is 1 and
the day/night ratio is 1.
3、 Prediction outcomes
From Table 5-7, we know that in day time of the construction period, the traffic noise
contribution value on the sensitive spots in both sides of transportation routes is
54.4~60.2dB(A), and the noise predicted value is 54.7~60.7dB(A). It is predicted that in
the transportation route 1 (2) time frame, the noise at Xinhe Village - south of bridge I
(M3) is 0.7dB(A) out of limits and other sensitive spots are all predicted to be up to
standard.

5.5.2 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.
First, use low noise equipment as far as possible, for example, use hydraulic
machinery instead of fuel machinery, and use high-frequency vibrorammer; for the
fastening mechanical equipment, excavation and earth moving machinery, such as
excavator and bulldozer, you can reduce the noise by exhaust pipe silencer and isolation of
motor vibration parts. Carry out regular maintenance and repair to the power mechanical
equipment. Timely 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.
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). Due to the engineering requires night-time
construction, the building unit and construction unit must file an application to the
Yingshang Environmental Protection Agency 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).
(3)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.
(4)The steel & wood processing factory of construction site shall be set in
temporary house and processing in night time is not allowed. The agitator and fixed
concrete delivery pump shall be set in the side away from the residential area to reduce
noise pollution.
(5)During the spoil transport process, reasonably arrange the construction time
and avoid night-time transportation of spoil; vehicles shall slow down in passing by the
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
131
residential area, honking the horns at will are not allowed, and try to reduce the influence
to their life. In addition, carry out construction period monitoring to the transportation
route 1 (2) section, Xinhe Village - South of bridge (M3), and when necessary, set sound
proof window to the first row of about 20 households and 6m2 to reduce the noise
influence to the residents.
(6)The building unit shall pacify the residents nearby together with the
construction unit, announce their construction timescale, and establish good community
relationship with the companies and residents along the routes. In addition, they shall set
complaint hot line during the construction period for the complaints about noises from the
residents, and actively handle the complaints.
5.5.3 Noise impact in operation period
The acoustic sources during the operation period are mainly ship navigation noise,
ship engine noise and ship whistle noise. The ships have low speed during navigation and
generate small noises, which are flowing acoustic source. The power-driven vessels use
diesel engine, and the engine has large noise, 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 ship whistle, which can be effectively
controlled via strengthened management, so we mainly evaluated the approach channel
ship noise impact during operation period.
According to Environmental Impact Assessment Specifications for Inland Waterway
Project (JTJ227-2001), the ship navigation noise radiation sound level shall be calculated
based on:
(Lp)i=(Lw)i+10lg(Ni/ViT)+10lg(D0/D)1+α-13
Where: (Lp)i······ the radiation sound level of i type ship per hour at location D,

Ni······· the average flow of i type ship in day time or night time, 12 ships/h

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 noise related materials, and see Table 5-8 for
the noise source intensity (at the location of 15m) of ships of different powers.

First, when the cabin door is open, predict the lockage condition to 1000t ship; and
see Table 5-9 for the noise sound levels of the noise sensitive spots of the lockage ship
According to the prediction results (Table 5-9), when the cabin door is open, the
noise values of 8 prediction points in day time are 51.9~59.0dB(A), and 49.4~53.1dB(A)
in night time, and the ship traffic noise contribution values are 46.4~51.7dB(A). The noise
increment is 0.4~8.6dB(A) in day time and 1.5~18.9dB(A) in night time. The 8
predictions points can meet the requirements in GB12348-2008 in day time and 7 of them
are out of limits in night time with 0.6~3.1dB(A) above the standards.
Second, the cabin doors are usually closed during navigation, so predict based on
closed cabin door and 1000t ship lockage condition; see Table 5-10 for the prediction
outcomes.
According to prediction outcomes (Table 5-10), the 8 predictions points can meet the
requirements in GB12348-2008 in day time and 1 of them is out of limits in night time.
The noise values of 8 prediction points in day time are 46.3~58.7dB(A), and
43.2~50.6dB(A) in night time; the ship traffic noise contribution values are
38.3~43.6dB(A), noise increments are 0.1~2.9dB(A) in day time and 0.3~11.1dB(A) in
night time. The night-time out-of-limits quantity for ship lock Administrative Office
neighborhood (M8) is 0.6dB(A), and the predicted noise increment is 0.3dB(A), mainly
because of the influence from S102 traffic noise.
By comparing Table 5-9 with Table 5-10, we can know that only 1 of 8 prediction
points is out of limits in night time after the cabin door is closed; closing of cabin door can
make ship noises’ impact to the sensitive spot in the day time reduce by 5.7dB(A) to a
maximum extent, and 7.8dB(A) in night time; during the navigation, closing of cabin door
has significant noise reducing effect, so we advise the building unit and ship lock
Administrative department to strengthen management and close the ship cabin during
lockage and navigation to reduce the impact of ship noises to ambient environment.
5.5.4Noise control measures in operation period
(1) The ship cabin door must be closed when the ship is navigating in the approach
channel and on lockage and the ship shall pass slowly.
(2) According to the noise prediction outcomes in operation period, after the cabin
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
134
door is closed, only the ship lock Administrative Office neighborhood (M8) among 8
prediction points is 0.6dB(A) above the standard in night time. It is advised to carry out
follow-up monitoring to the ship lock Administrative Office neighborhood (M8) in the
operation period; when necessary, install ventilation sound proof windows (the noise
reduction effect of general ventilation sound proof window is 25~30dB(A)) to 7
households of the first row in the sensitive spot; 6m2 for each household and 42m2 at total,
you shall have 42,000 Yuan of budget for noise environmental protection fee.
(3) Advise the building unit and ship lock Administrative Office to strengthen the
management and use sound devices as specified in ship safe navigation provisions; do not
honk whistles at will and forbid any whistle in night time to reduce the impact of ship
noises to ambient environment. Weed out the ship type that does not conform to
environmental protection standard requirements. The ships in operation must be installed
with qualified gas discharge silencer to control the noises. Make sure the green coverage
ratio in the ship lock area and both sides of approach channel will meet the environmental
protection requirements, and plant trees on the ship lock Administrative Office and both
sides of approach channel to reduce the noises.
(4) After the Yingshang 2nd waterway ship lock is built, they will use LED screen
instead of radio to play lockage safety regulations. If you need to use the radio in special
circumstance, the radio frequency of use shall be controlled and it is not allowed to use
radio in night time.

The solid waste generated in the construction will be stacked on the spoil area. Via
settling of the slurry and drilling cuttings and strengthening of management to
construction process environment, you can effectively avoid or mitigate the adverse
influence to surface water body and quality.
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 garbages and sundries, clean and level the
household garbages, outdoor toilets and sewage pit, use quick lime to disinfect and do the
construction slash recovery right.
The construction contractor shall arrange someone to collect the production waste,
the scrap iron, scrap steel, and waste wood pieces shall be stacked in specified positions
instead of leaving around; the waste materials shall be recycled and treated together.
During the transportation of household garbage and building materials, they shall be
enclosed or covered to avoid fall-off of garbage, sand or soil.
The total household garbages generated by the construction workers during the
construction period are expected to be 180t; you need to set trash cans in the construction
camps and arrange specially-assigned persons to clean and transport the household
garbages. 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 garbages
shall be collected and transported by the local sanitation department in a timely manner.
5.6 .2Operation period
The solid wastes in the operation period are mostly the household garbages 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 28 new working personnels on
the ship lock will produce 9800kg/a garbage. The household garbages in the operation
period shall be handed over to the local sanitation department for transportation and
treatment after the collection.

6 Risk Analysis
6.1 Pollution Source of Dangerous Chemicals
For water transportation, of all pollution incidents, leak of dangerous chemical due to
the collision of the vessels carrying chemicals will have the severest impact over the
environment. In case any accident occurs to a vessel during its sailing in the channel, the
maritime authority of Fuyang will launch its contingency plan. Large rescue and salvage
ships and devices have been provided in the emergency system of Fuyang Maritime Safety
Administration. For accident handling and rescue on the channel, the maritime authority
will play a major role.
This assessment will focus on the leak of dangerous goods due to collision of ships in
an approach channel or a lock chamber, or the leak of dangerous goods due to the fault of
a ship carrying dangerous goods.
According to the statistics of the goods passing the Yingshang Ship Lock, the goods
are mainly coal, ore, building materials, grain, chemical fertilizer and a few chemicals.
Among other things, the chemicals are mainly urea, compound fertilizer, methanol and
hydrogen peroxide produced by Linquan Chemical Base in the hinterland by the Shaying
River. Such chemical products are normally transported to the Huai He River channel
through the Cihuaixin River downstream of Jieshou. Only when the Cihuaixin River is not
available for navigation, such chemical products enter the Huai He River through the
Yingshang Ship Lock. According to the forecast of shipment volume during the operation
of the 2nd waterway ship lock, total 305t cargoes of chemical materials and products will
pass the lock in 2020, the number will be 395t in 2030, and 580t in 2050.
According to the existing goods types and forecast of transportation in feasibility
study, the chemical materials transported by this channel are mainly methanol, urea,
synthesis ammonia and hydrogen peroxide.
6.2 Accident Rate
The 2nd
waterway ship lock will expand the navigation capacity of the Yingshang
Ship Lock; besides, the channel improvement of the Shaying River is being implemented,
when the harnessing is completed, the river course will be improved and more ships will
be attracted to the Yingshang Ship Lock. Such accidents as ship collision or shipwreck
may occur in the channel occasionally. Investigation indicates that no ship collision or
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
149
dangerous chemical leak has occurred since the Yingshang Ship Lock is open to
navigation.
According to the statistics of the Yingshang Ship Lock, collision and shipwreck in the
approach channel or the lock chamber belong to small probability events; but according to
the principle of the Probability Theory, small probability events are possible. In case of
such adverse events as leak of dangerous chemicals due to ship collision, they will have
serous destructive influence over the waters, fish might be killed or other creatures are
poisoned.
6.2.1 Influence over Aquatic Ecology and Fishery Resources
In case of chemical leak due to ship collision, the influence on the aquatic ecology of
the Ying 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 Ying 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.
6.2.2 Influence over Water Quality
The site investigation and the consultation with relevant authorities find there is no
potable water intake on the Shaying River channel where the Yingshang Ship Lock is
located. However, leak of chemicals may have influence over the water in the channel.
The influence of the leak of soluble chemicals is decided by the leakage amount and the
speed in handling with the accident. Minor leakage, speeded response and rapid control
measures may minimize or eliminate the influence over the water quality. So management
must be strengthened. Precautions shall be put into practice. A contingency plan shall be
formulated to minimize the hazard of the accident to the water environment. Both
prevention and rescue shall be highlighted.
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock

6.3 Precautions Against Risks
6.3.1 Safety in Navigation, Anchorage and Lockage
Safety and pollution prevention measures shall be taken for the ships carrying
flammable, explosive, corrosive, hazardous or radioactive goods. Specified signs shall be
displayed, the provisions in the Regulations Governing the Supervision and Control of
Vessels Carrying Dangerous Goods and the Regulation on Inland Waters Transportation
Safety Management of the People’s Republic of China by the Ministry of Transport of the
People’s Republic of China shall be followed.
Any ship passing the lock shall subject to the general direction and dispatching by the
lock management authority and relevant provisions on navigation safety shall be followed.
Forecast, early warning and protection shall be provided in the days wifth frost, thick fog
or gale. A ship carrying dangerous goods can only pass the lock only the names, properties,
packages, pollution classes, precautions and emergency measures for the dangerous goods
are reported to and approved by the ship lock management authority. The ship lock
management authority shall arrange a ship carrying dangerous goods to anchor and pass
the lock separately.
During a flood control period, ships shall be subject to the general arrangement by
the flood-control headquarters; safety measures and equipment protection measures for
flood control shall be taken.
6.3.2 Accident Emergency Measures
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 Regulation on the Safety Management of Hazardous
Chemicals, the Regulations of the People's Republic of China on the Administration of
Traffic Safety in Inland Waters 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.
(1)To ensure that help can be received in case of emergency in the project zone, the
Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock
151
administration office shall prepare a contingency plan against accidents; once emergency
occurs, it shall timely report local government, the Maritime Safety Administration and the
EPA of Fuyang, actively organize emergency actions, timely salvage and rescue sunk
articles, to ensure the waters environment is safe and the ship lock is unobstructed.
The chemical materials transported by this channel are mainly methanol, urea and
synthesis ammonia. Investigation finds that all of such raw materials are held in sealed
containers; after shipwreck, leak is unlikely to occur, but timely 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 Shaying River may
not be used; after the accident is dealt with, the inhabitants will be notified again.
(2) Emergency facilities for accidental spill
At present, large rescue and salvage ships and devices have been provided in the
emergency system of Fuyang Maritime Safety Administration. For accident handling and
rescue on the channel, the maritime authority will play a major role. The project company
shall shall cooperate with Fuyang Maritime Safety Administration in the equipment
system, formulate a cooperation plan to facilitate allocation of emergency teams and
devices.
For the accident occurring on the approach channel, the operator shall provide
necessary emergency rescue devices and instruments at the Yingshang Ship Lock
Administration Office to facilitate emergency help. They mainly include emergency
vehicles for protection and handling, antidotes, solid and liquid substance cleaning and
recovering devices, rubber plugs and sandbags; the emergency devices to be provided for
this project are listed in Table 6-1.

10.2 Status Quo of Environment Quality
10.2.1Status Quo of Environmental Quality
Pollution index of SO2, NO2, PM10 and TSP in the air within the project appraisal
area is below 1; air quality of the area conforms to Class II of GB3095-1996 Ambient Air
Quality Standard. Air of this area is good.
10.2.2 Status Quo of Environmental Quality of Water
Surface water environment: monitoring factors of pH, DO, petroleum and fecal
coliform in all sections conform to Class IV requirement of Environmental Quality
Standard for Surface Water (GB3838-2002); SS conforms to standard limit values for
drought-enduring plants in Standards for Irrigation Water Quality (GB5084-2005); total
nitrogen content and total phosphorous content in the three monitoring sections exceed
limit value; superstandard multiple of total nitrogen and total phosphorous is 3.05 and
0.62.
Environmental Quality of Groundwater: all index of water at monitoring spots of
down stream approach channel conform Class III requirements of Underground Water
Quality Standard (GB/T14848-93) and many index have reached Class I standard.
Environmental quality of underground water near the approach channel is good.
10.2.3 Status Quo of Environmental Quality of Sound
Based on noise monitoring result, noise status collected at 1#, 2# and 3# monitoring
spots on April 26 and 27 of 2013 conforms to Class II requirements in Environmental
Quality Standards for Sound (GB3096-2008), but the noise level at 4# monitoring spot in
the evening was over high, namely 3.8 to 2.4dB(A). Travelling tractors on the bridge
mainly contributed to the over high noise.
Environmental Impact Report on Shaying River Yingshang 2nd Waterway Ship Lock Project
186
10.2.4 Environmental Quality of Sediment
Content of heavy metal pollutants in sediment of Shaying River is lower than Class II
standard in Environmental Quality Standard for Soils (GB15618-1995). Such sediment
can be used for farmland or shelterbelts after it is naturally dried in the dump site. Heavy
metals in such sediment will not harm plant growth or the human.
10.2.5 Investigation and Evaluation of Ecological Environment
Located within farming area, the expansion project has good artificial vegetation on
its site and there was no national or provincial level protected rare wild animals and plants;
soils in the region are mainly black soil mortar and fluvo-aquic soil; soil erosion mainly
caused by water and the degree and extent of erosion is minor。
10.2.6 Water and Soil Loss
According to Standard for Classification of Soil Erosion, the project site belongs to
northern earth-rocky mountainous area, and its soil erosion is mainly caused by water,
reflected major in surface erosion and minor in ditch erosion. Maximum permissible value
for soil erosion in this area is 200t/km2·a. The responsible entity made an investigation on
background values of the soil erosion in the project region. The project region has
considerable crops and few arbors on it, and the soil of this region has weak erosion and a
soil erosion modulus of 200t/km2·a or so. By on-site survey and learning from local
departments, it is believed that the soil erosion modulus is basically consistent with given
value.
10.3Prediction and Assessment of Environmental Impact
10.3.1 Social Environment
Traffic disruption during construction would adversely affect passage of vehicles and
pedestrians. Focus on constructors’ health and access of constructors from other places
should be highlighted to prevent possible social security problems. The impacts will not
last long and they will disappear once the construction period ends. However, the
construction units should intensify their efforts to minimize the inconvenience to traffic;
education on constructors and publicity on construction process should be carried out well,
thus to let people around the project site know more about the project and the constructors.
All in all, the project construction will not leave an enduring major impact on local
farmers’ life quality.
Environmental Impact Report on Shaying River Yingshang 2nd Waterway Ship Lock Project
187
10.3.2 Ecological Environment
The construction site belongs to rainfed agro-ecological function zone within the
plains in the North of Huai River. Lands covered by the construction site mainly include
water surface, farmland, forest and grassland, land for water conservancy facilities and so
on; there is no protected species in and around the project area and the project occupies
little water resource; vegetation of the site may be damaged during the construction period,
but it can be restored by green land, restoration of temporarily occupied land and greening
measures such as planting trees and grass. So it will not have a seriously adverse impact
on ecological environment.
10.3.3Atmospheric Environment
(1)Construction Period
The greatest impact on ambient air during construction period arise from air-borne
dust, and exhaust of burned gas and other fuels produced in transportation or equipment
operation also contribute to pollution of atmospheric air. Air-borne dust on the
construction site is mainly from excavation of foundation pits, quarry mining, abandoned
dreg heaping and vehicle transportation and the most serious pollutant is TSP. It will have
certain impact on constructors having long-term exposure to dust and residents along the
road. The construction unit should take measures such as spraying water, strengthening
management and intensifying protection for on-site workers to reduce air-borne dust by
50% to 70%, and effectively reduce the influence of air-borne dust to ambient air.
As transportation and construction equipment’s operation bring in relatively little
pollutants, and such pollutants are mobile and well diffusive at the construction site, so it
will not have much bad influence on the quality and function of ambient air.
(2) Service period
During service period, major oil-fired exhaust from ships is CO and NO2 discharged
in voyage. The local air condition is good for exhaust to diffuse, so the air quality will not
deteriorate. The extension project area can meet the requirements for Class II area in
Environmental Quality Standard for Air (GB3095-2012).
10.3.4 Water Environment
(1) Construction Period
During construction period, building of structures in water increased suspended
solids of surface waters; waste generated during construction includes contaminated oil
from construction machine (drip or leakage of oil), contaminants from building materials
and discarded substances eroded by rain, residual water from sediment, discharged water
Environmental Impact Report on Shaying River Yingshang 2nd Waterway Ship Lock Project
188
from foundation pit, sewage from rinsed sand and stone. Of all the contaminants,
suspended solids and petroleum account for the most percentage.
Untreated discharge of construction sewage will contaminate the ship lock reach to
some extent. Oil separation, precipitation and intensified management of environmental
protection during construction can effectively avoid or ease pollution of surface water.
Domestic waste on construction site was mainly formed during construction workers’
daily life. Construction workers are suggested to rent house, or set permeability-reducing
dry pail latrine and clean it regularly
(2) Service Period
During service period, domestic sewage discharged by ship lock workers and screws
on board, and contaminated oil from ships form major portion of waste, in which COD,
NH3-N and petroleum are considered as principal pollutants.Major functions of Shaying
River include transportation and irrigation. No centralized drinking water feeders are
provided, and volume of domestic sewage meeting national discharge standard is very
limited, so the water in Shaying river is not much affected.
Sewage from the ship lock administration center can be used for greening in the
center once it is treated by underground integrated sewage treatment device; additionally,
it is suggested to keep a close eye on planning sewage pipelines of Yingshang County.
Once sewage discharged from the center can be incorporated into the municipal pipeline
network, realize it. According to requirements of harbor approach administration, any ship
is not allowed to discharge contaminated oil and water at the bilge when it is passing the
ship lock.
10.3.5 Acoustic environment
(1) Construction Period
Reconstruction of ship locks and road bridges and construction of connecting
engineering would have certain influence on local households. This construction project
lies between the two banks of the approach channel, and the sensitive spot is more than
150 meters away from the construction site. Corresponding standards can be met during
the day, and certain impact will be left on surrounding sensitive spots at night. Analysis
shows that the steel and wood processing site generates higher noise, so the processing site
should be placed within interim room to reduce noise and meet noise control standard
during the day, and at night when measured beyond 281 meters. According to environment
assessment, it is suggested to ban large construction machine from operation during night.
Construction during night is unavoidable for the project, so the builder and the
Environmental Impact Report on Shaying River Yingshang 2nd Waterway Ship Lock Project
189
construction unit should apply to Environmental Protection Agency of Yingshang County
for construction during night, and inform neighboring residents of necessary precautions.
According to the assessment, the construction unit should intensify environmental
management, and push the construction unit to strictly follow Emission Standard of
Environment Noise for Boundary of Construction Site (GB12523-2011), and improve
equipment management and control construction period.
During day time, traffic noise from construction at sensitive spots on both sides of
transportation lines ranges from 54.4 to 60.2dB (A), and predicted noise is 54.7 to 60.7dB
(A).At Xinhe Village --- Qiaonan I (M3) of transportation line 1(2), predicted noise
exceeds maximum permissible value by 0.7dB (A), and noise any other sensitive spot is
up to the standard. It is recommended to keep track of the sensitive spots with excessive
noise, and 120 square meters of ventilatory sound-proof windows should be reserved.
Construction of ship lock and road bridges will have certain impact on neighboring
sensitive spots. All sources of noise during contraction period is temporary, and they exert
influence in short period and within limited area. Once the construction is over, such
negative influence will disappear.
(2) Service Period
During service period, major sources of noise are sailing ships, ship engines and ship
sirens. Analysis shows that during service period above sources of noise have certain
impacts on neighboring sensitive spots. The construction unit and the ship lock
administration agency should intensify their management. Once any ship entered the
approach channel or was passing the lock, doors of engine room should be closed and such
ships should sail at lower speed. Use of sound mechanism should follow relevant
stipulations on safe navigation of ships. Limit ship horn and forbid siren sound at night,
and relieve impact of noise on neighboring environment. Ships inconsistent with
environmental protection requirements must be eliminated. Qualified discharge silencer
must be mounted to ships in operation to ensure its normal operation. Discharge noise
must follow Regulation on Noise Levels on Board Inland Ships. Afforested area rate for
the ship lock and two banks of the approach channel must meet environmental
requirements. Trees should be planted at the ship lock administration center and the two
inner sides of the approach channel.
According to noise prediction for the operation period, once engine room doors are
Environmental Impact Report on Shaying River Yingshang 2nd Waterway Ship Lock Project
190
closed, only relative's courtyard (M) for the ship lock administration agency at night fails
to meet noise control requirement among eight predicted points, and the noise exceeds
maximum standard value by 0.6dB (A).It is recommended to keep track of the relative's
courtyard (M) for the ship lock administration agency. If necessary, mount ventilation
sound-proof window (the window can reduce noise by 25~30dB (A)). There are seven
users, 6 meter squares for each household. If the window valued 1000 Yuan/square meters,
42000 Yuan is needed to protection environment
Security regulations on ship lock passage will be broadcast on LED screen once the
Yingshang 2nd waterway ship lock is completed, so it needs no broadcast generally. If
broadcast is necessary in certain cases, use frequency should be controlled and never
broadcast at night.
10.3.6 Solid Waste
Solid waste produced during the construction period of ship lock expansion project is
mainly the earthwork excavated by engineering excavation and the living garbage
produced by the construction personnel. The discarded earthwork was carried to
dumping area. All kinds of earth cofferdam (including bag packed soil) fills 9152m3, all
are used for excavation, after completion, excavated and transported to dumping area. Try
to collect the recycle the wasted slag. The living garbage produced during service period
and construction period should be collected and given to the environmental protection
department for disposal.
10.3.7 Impact on Flood Control
Yingshang 2nd waterway ship lock project has no adverse effects on the existing
channel and the flood control of the nearby area, the implementation of the project
conforms with the relevant industry planning, the designed flood control standard and
standard of construction diversion meet the specification requirements, the engineering
construction basically has no impact on the flood capacity of Shaying River, it will not
affect the channel river regime, after taking engineering measures, it will not affect the
flood safety of the channel nor affect the emergency flood fighting, there will be no
significant influence to the legal water rights of a third party. The engineering generally
fulfills the flooding safety requirement.
10.3.8 Risk Analysis of Accident
According to the forecast of the carrying capacity during service period and the
Environmental Impact Report on Shaying River Yingshang 2nd Waterway Ship Lock Project
191
relevant statistical results, ships coming and going are mainly for coal, building materials
and chemical materials transportation, coal or building materials etc falling into the water
will have a small influence to the water quality, but the chemical material may have big
influence if falling into the water, for this environment impact assessment, risk analysis is
mainly made for transportation of chemical material.
Hazardous chemicals etc generally have greater toxicity; it may cause serious water
pollution once being leaked. The assessment requiring the construction unit to strengthen
the safety of ship and berthing, prepared well for the prevention of accident. For an
effective treatment of sudden pollution accident and strengthening the emergency
treatment responsibility, to control the hazard of the pollutant in maximum extent, the
assessment requiring the construction units to formulate emergency plans in accordance
with the relevant laws, rules and regulations.
10.3.9 Analysis of Water and Soil Loss Influence
According to the results of soil and water loss estimated, the total amount of soil and
water loss during construction period is 5472.3t, the background loss is 384.1t, and the
newly added loss is 5088.2 t.
The construction of this project has good economic and social benefits; it has obvious
effect on promoting the social and economic development of the local area. Although the
construction may cause destruction to the original landscape and produce discarded soil
which may cause water and soil loss, through the development of soil and water
conservation plan, taking corresponding measures, an effectively prevention can be made
control the possible water and soil loss, it is possible to reduce the soil wand water loss
caused by construction.
10.4 Conclusion of Assessment
The 2nd waterway ship lock engineering on Shaying River channel plays an
important role in realizing shipping development planning of the Country and Anhui
Province, improving the regional high-grade channel network upgrading, dredging the
impeding navigation node of Shaying River and expanding its capacity, exert the scale
benefit of shipping, pushing the integration of regional resources and economic integration,
driving the resources development and social economy developed in a coordinated way, it
has a great significance to the local economic development.
The 2nd waterway ship lock engineering construction on Shaying River channel may

have impact of different extent on the surrounding environment, but after strictly
implementing all kinds of environmental measures in the report, the impact on the
surrounding ecological environment can be reduced to an acceptable extent. So, with the
precondition of carefully implementing the corresponding environment rules and policies
of the Country and Anhui Province and strictly carrying out the system of “three
simultaneity”, considering from the viewpoint of environment protection, the 2nd
waterway ship lock construction on Shaying River is feasible.
