PREFACE
Bengbu, 33°01’~32°49’N and 117°31’~117°11’E, a municipality directly under
leadership of Anhui province is an important industrial, commercial and high tech
city in north Anhui. Since it is located at the significant joint of Jinpu Railway and
Huaihe River, it is also the hub of highway and waterway. As one of the major
cities along Jinghu High Speed Railway, the high speed railway zone
development will be the a hard to obtain historic developing opportunity for
Bengbu, thanks to the significant combined advantages of the costs of land, labor,
office and transport, and the landscape and traditional industrial and scientific
research foundations.
Nowadays, in Longzi Lake District of Bengbu City, the urban infrastructure of the
systems of drainage, the supplies of water, power, gas, and telecommunications
and roads are not perfect; the rainwater and sewage are directly discharged into
Longzi Lake and Baojiagou Ditch and finally into Huaihe River through
underground infiltration, as a result, to deteriorate Huaihe River water quality.
According to the special drainage plan of Bengbu, the rainwater system of Gaotie
area in Longzi Lake district belongs to Longzi Lake and Baojiagou Ditch water
division sub-area, the rainwater is discharged into Longzi Lake and Baojiagou
Ditch firstly through the collection with rainwater Subsurface Networks; the
sewage system being of Yangtaizi sewage system, the sewage is first collected
with sewage Subsurface Networks, then lifted by the pump stations at Tanghe
Road and Shenglidong Road and finally enters into Yangtaizi Sewage Plant and
discharged into Huaihe River after the water quality up to the standard.
To improve the water quality of Longzi Lake and Baojiagou Ditch, and eventually
that of Huai River, and to improve the infrastructure of Longzi Lake District,
Bengbu Investment Group Co., Ltd is planing to build Lilou Road (2609.3m) and
Fengandong Road (2813.24m). The subsurface networks for Lilou Road is 2.6km,
and 2.8km for Fengandong Road.
In compliance with the related national EA laws, regulations and World Bank
safeguards policies, the “Environmental Impact Assessment of the Project of
Constructions of Lilou Road and Fengandong Road and Their Subsurface
Networks in Longzihu District (Draft Delivered for Examination)” was worked out
in Mar. 2012. On Mar. 31, 2012, an expert panel was invited by Bengbu Municipal
Environmental Engineering Assessment Center to exam the statement. According
to the comments of the experts, some necessary revisions and supplementations
were done by our institute and worked out “Environmental Impact Assessment Of
The Constructions Project Of Lilou Road And Feng’andong Road And The Main
Subsurface Networks In Longzihu District (Draft Delivered For The Examination
And Ratification)” and is now presented to the superior competent authority for the
ratification. The report has been updated based on World Bank comments in
AIES Environmental Impact Assessment

1 INTRODUCTION
1.1 PURPOSE OF ASSESSMENT AND GUIDE IDEOLOGY
1.1.1 Purpose of Assessment
The infrastructure construction is a far-reaching developing activity to society and
economy and its building and operational period will also render a certain
influence over natural environment. This purpose of the environmental impact
assessment is as follows:
(1) Through the environmental impact assessment along the project lines, the
reasonability and feasibility of the of the project are verified from the view of
environmental protection and the comparison between the major and
substituted plans are also done so as to furnish the necessary scientific
foundation for project selection;
(2) Through the investigation of the social and natural environment along project
lines, focusing on design, construction and operation periods of the project,
the project’s construction impact towards the environment is predicated and
the related environment protection measures and proposal are recommended;
(3) The environmental protection measures, proposals and appreciation
conclusion are feedback to project design and construction to provide the
reasonable ground for the optimization of project design to reduce or relieve
the negative impact to the environment due to project construction;
(4) The project construction feasibility over the environment has been identified so
as to provide the scientific ground for project environment management and
project decision-making.
1.1.2 Guiding Ideology
The guiding ideology of this assessment is to utilize the existing basic documents
and use of reference of the related urban infrastructure construction project
assessment result, reasonably determine the assessment range, supervision
project on the basis of detail engineering analysis, in compliance with the
requirements of “The Technical Guide of Environmental Impact Assessment” and
“Environmental Impact Assessment Criterion of Road Construction Project”, and
according to the characters of project, chose the typical supervision points,
monitoring factors and predication moulds so as to achieve the reasonable,
practical, just, distinct and trustable targets.

investing environment and attract the investors to make it a breakthrough of
exterior orientation economy to promote the city and whole regional prosperity.
Today, the urban infrastructure such as drainage system and the supplies of water,
power, gas, telecommunication and roads are not perfect enough, therefore, the
quick building of the infrastructure engineering, Lilou and Fengandong Roads are
not only the necessary condition important measure for city fast development but
also the demands for perfecting the city infrastructure construction and supporting
system for eastern group.
2.4.2 The Conformity Analysis for Bengbu Urban Comprehensive Traffic Plan
In the main city plan, the road network takes Huaihe River as natural axis and the
road is basically distributed in paralleled and vertical ways to the river. Since it is
separated by the river, there is unbalance economic development between the
main city area and that of northern riverside; the traffic across the river is
considerably poor and the facilities across the river needs also to be improved.
With the strategy decided to by the municipal Party committee and government to
extend the city scale and stepping over the river in Mar. 2004, Huaishang District
was established in the old city area north riverside to make the city planning road
network become the “one ring-four lateral-three longitudinal” pattern.
The “one ring” means to form Feihe Road, Laoshan road, Nanwaihuan Road and
Daqing Road as quick route shaping ring type quick traffic to improve urban
developing space and transit passage transport, perfect urban communication
environment and lay a solid foundation for city expansion.
The four-lateral-three-longitudinal” pattern means the main road system to secure
the city interior space connection, in which “four lateral” means Huaishang
Avenue, Shengli Road, Donghai Avenue and Huangshan Avenue; the “three-
longitudinal is the Chaoyang Road-Fengyuan Avenue, Jiefang Road and Gaotie
dong Road.
The Lilou Road and Fengandong Road to be newly built are the planned city main
roads, the details refer to Fig. 2-4-1 – Overall Traffic Plan Map of Bengbu City.

4. Road Foundation Design
The road foundation shall be constructed in layers and rammed evenly; the road
foundation compactness adopts heavy tamping standard: the detail see Table
3-4-1. The compactness of pipeline grooves within the road foundation is equal to
the road foundation tamping requirements; the modulus of resilience of top of the
road trough shall not less than 30MPa.

Digging 0~30 95/98 93/95 90/92
Note: The figure in the table is heavy tamping standard; the denominator is light tamping
standard.
This road foundation designed filling road section embankment side slope is of
natural slope at 1:1.5, the digging road section embankment side slope is of
natural slope at 1:1. When the road embankment extends through ponds and
rivers, the normal water level + 0.5m below to water bottom side slope is at 1: 1.75,
that approaching water level shall be sealed with mortar masonry protection of the
thickness not less than 0.6m; the normal water level + 0.5m above road
foundation design elevation side slope is 1:1.5.
As for the ditches and ponds which road extends through, when the mud
thickness is less than 2m, the mud shall be first removed and then the road
foundation built, each tamped layer thickness shall be less than 30cm; in case
mud is more than 2m, first remove the mud (1.5m down to top), squeeze the mud
with rock blocks (diameter more than 30cm), then fill and build the road foundation
and finally do the overload pre-compaction (1m high and pre-compactness for
more than 1 month).
5. The Design of Road Intersection Connection
(1) Design Principle
① Meet the requirement of overall transport function and the urban planning
construction areal service;
② Further analyze and study the planned road network, determine
reasonably current plane intersection type and road traffic organization etc. and
settle well diversified vehicles’ demands over the traffic to meet the areal traffic
functional demands;
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
60
③ Select the technical index for plane crossing canalization design
reasonably, secure driving safety, furnish satisfied direction identifying and
eliminate various factors causing drivers to make mistakes;
④ Do the crossing canalization design for the main intersections which
mainly depend on traffic volume forecast. After the calculation of the intersectional
traffic capacity, lanes expansion design of the entrance and exit of main
intersectional crossing can be done to compress central isolation belt width, widen
redline width; traffic signal lamp control shall be used for main road crossing with
sub-main road; when branch road meets main road and sub-main road, the
vehicle driving discipline of “main road in priority” shall be carried out, i.e. when
the vehicles running on main and sub-main roads, the vehicle on branch road
shall wait and enter into main road until those on main road pass first.
(2) Canalization Design of Plane Intersection
① Since the traffic capacity of intersections is less than road section, in order
to enhance traffic capacity of intersection, the design measure of increasing lanes
numbers shall be used. As for the main-main intersections in the design, the
division lines and physical division islands shall be arranged in terms of crossing
types and special right/left turns lanes shall be widened in road’s entrance and the
straight lanes remain same, at the exist, a lane combined with public bus bay shall
be widened for right turn acceleration; that shall not be widened as the
main-sub-main road and main-branch roads.
② The all line opening intersection uses traffic signal lamps control; when the
auxiliary road’s main roads meets sub-main/branch roads, the semi-closed
crossing shall be applied to organize the traffic, i.e. when vehicles need to enter
into sub-main road, they shall first go from fast lane and turn right into auxiliary
road, then go out in right turn from auxiliary road and enter into main road so as to
approach the fast driving out; when vehicles need to enter into main road, the
vehicles on sub-main road shall go in right turn into the auxiliary road of the main
road and then go into fast lane from the auxiliary road so as to realize the fast
leaving.
③ The U turn lane designed in the intersection and marking guide installed
on oncoming lanes will guarantee traffic safety.
(3) The Specific Design of Intersections
① Design of Pedestrian Crossing
Since the intersection is wider and pedestrian cross is longer, in order to
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
61
secure the pedestrians safety, the marking canalization safety stop zone in central
junction green belt is designed. This projected stop zone has central division belt,
which is the same width with pedestrian crossing and its road surface is paved
with tiles.
② Length Expansion Design for Entrance and Exit Lanes
In this project, a left turn and right turn special lanes each are added to the
main-main road intersection, the lanes gradual change section is 40m long, left
turn expansion section is 80m long and right turn expansion section is 60m long.
In the exit, right turn lane is designed, its expansion width section is 80m long
which is used jointly also by public bus (in which public bus station is 20m long)
and the gradual change section is 40m long.
③ Numbers and Width Design of Lanes
In this project design, the entrance lanes numbers are the road section lanes +
left/right turn special lanes and exit section lane number are same with road lanes.
Entrance section single lane width is 3.25m and exit single lane width is 3.5m.
④ Vehicle U turn Design
U turn is designed at the joint of the left turn special lane and gradual change
section, vehicle’s U turn does not influence left turn vehicle flow. Meanwhile
marking guide is installed for the oncoming lanes to secure traffic safety. The U
turn lane break width is 10m.
⑤ Intersectional Interior Vehicle Flow Guide Line Design
A Division island is designed at main-main intersection to manage pedestrians,
non motor vehicles and motor vehicles go or drive across roads in order.
⑥ Connection Design between Entrance Lanes and Road Section
Whether or not the connection and transition between intersection entrance lanes
and road section is reasonable will influence the intersection or even complete
road traffic status and this project design plan is as follows:
a. Canalization line is plotted in transition section to let the transition point of
oncoming vehicle flow interlaced each other so as to eliminate the unsafe factors
such as the scratch and collision from oncoming vehicle flow which use the same
transition point.
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
62
b. In the transition zone, connection lines between road section and entrance
lanes are added. Lanes are increased from road section to entrance. In order to
facilitate the smooth connection, a gradual change section of 40m long is added.

⑦ The Intersection Design between Lilou Road and Fengandong Road
This intersection is main-main joint intersection, Fengandong Road cross section
is 4 plate type and the lateral division: 7m middle division belt + 2 x 11.75m motor
lanes + 2 x 2.5m green belts + 2 x 4m non-motor vehicle lanes + 2 x 3.25m
pedestrian lanes = 50m.
Division island design is adopted to separate the right turn lanes out so as to
organize pedestrian and non-motor vehicle cross the road in order and let the
intersection safe and traffic smooth. The traffic signal lamps are design as well.
This intersection is designed with 4 public bus stations, which are all located at
the special entrance right turn lanes.

3.9 MAIN POLLUTANTS AND POLLUTION SOURCE ANALYSIS
3.9.1 Construction Period
The main pollution source in construction period comes from the noise of
machineries operation, raised dust and the waste water and waste gas in
construction sites etc. and the ecologic influences due to the farmland occupying
and excavation as well.
1. Source of Noise
The noise in road construction period comes mainly from those of various road
building machineries and the actual test over the noise of such common

2. Waste Gas
The main air pollution source in this project construction site:
① The raising dust from the operations of road breaking, earthwork digging
and earthwork filling;
② The raising dust of the road breaking, vehicles driving in the construction;
③ The raising dust due to wind force;
④ The dust caused by the houses demolishing and materials load and
unload etc.
In terms of this analysis, under the fine weather and the building site not watered,
after the comparison of TSP concentration monitoring, the result is as follows:

3. Waste Water
① The oil/dirt of the leakage from the construction machineries and the oil
contained waste water from the open air machineries etc scoured by rainwater;
② The water pollution contaminated by living waste water and living rubbish
in construction site, the major pollutants are SS、BOD5、COD etc.;
③ The water body pollution caused by the piled building materials and soil
and sand/stone from excavated earthwork scoured by rainwater, the main waste
water’s pollutants are SS.
4. Solid Discarded Materials
The solid discarded materials in construction period are mainly building rubble
and demolished gravel etc generated from the construction process. The primary
assessment refers to as Table 3-9-3.

5. Social Environment Influence Source
The main Subsurface Networks layout will cause the problems of resettlement
losses and labor reorganization due to the demolishment, such layout will also
influence to a certain extent to towns planning along the Subsurface Networks line,
however, the road building can bring more job opportunities to the residents and
improve economic development along the line.

6. Ecologic Environment Impact Source
The project area is mainly in the city planning region, its construction period
impact over ecologic impact mainly lies in: the impact over the ecologic
environment due to the land occupation; the green land area change due to the
construction and permanent land occupation and soil erosion caused in the
construction period.
① Ecologic Environment Impact due to Land Occupation in Construction
period
In this project period, the necessary large amount of earthwork digging will be
caused to destroy the local original plants and make the said place non-
vegetation area; meanwhile, the vegetation growing condition will also change.
The new soil parent material exposed in the excavation area assumes low organic
substance contents and poor soil quality since the soil is not under the maturing
process. At the same time, the operation of the building machineries will also
destroy more or less the plants. After the project, as the time lapse and soil
maturing, plants will have the recovering changes under the new natural
conditions and return to the original plants gradually.
② Green Land Area Change
The green land change volume refers to Table 3-9-4
Table 3-9-4 Green Land Change Volume
Type of Green land Green land occupied area
(m2)
Compensated area (m2)
Farm land green

Dry land 68858 /
Water area 27101 /
Urban green land / 65070.5
Total 229267 65070.5
③ Soil Erosion Impact
The original land condition will be changed due to piling up of building materials,
waste construction soil and water supply/drainage pipelines laying in the building
sites and certain soil erosion will be also caused due to the temporary earthwork
piled in the building site under raining season and windy weather.
In this construction, the original land structure will be destroyed and changed due
to the road excavation and earth-taking, which further cause the original soil
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
86
shifting and loose, and vegetation destroyed, land surface exposed so as to
change soil erodibility and vegetation state to lead to the deterioration of soil
erodibility and poor ability to resist rainwater scouring.
These project operational pollutions mainly come from vehicles tail gas and traffic
noise after traffic running and ground rainwater runoff.
1. Vehicles Tail Gas
Vehicle gas consists of three parts, 1st – the gas exhausted from vehicles’
combustion system which contains the pollutants such as CO、THC、NOx
accounting for 60% of the total exhaust; 2nd – the gas exhausted from crankcase,
such as CO、CO2 accounting for 20%, 3rd – the gas comes from carburetor
combustion system’s THC etc accounting for 20%.
Motor vehicles tail gas contents are complicated but the exhausted major
pollutants are CO、THC、NOx etc. These pollution sources belongs to linear
flowing pollution source, as to urban roads, vehicles tail gas impacts very much to
the area within 20~50m, the area out of 50m is less polluted as the distance far
way more and more.
Moreover, the tyres of running vehicles on roads make the dust blown off on road
surface to cause 2nd dust pollution. When the bulk materials which contain dust
are transported, those materials will also produce blowing dust due to dropping
and wind blowing etc.
In line with the recommended values from “The Criterion of Environment Impact
Assessment for the Road Construction Projects issued by Ministry of Transport”,
the single vehicle pollutant emission index of under the speed of diversified typical
vehicles refers to Table 3-9-3.
Table 3-9-3 Single Vehicle Pollutant Emission Index

pollutant’s single vehicle emission factor in forecast year mg/ (vehicle).
In line with the above equation, the vehicle waste gas emission source intensity of
diversified road sections refers to Table 3-10-4.

2. Noise Source Strength Analysis
When the road is in operation after the project, the noise source comes mainly
from the traffic noise caused by the diversified running vehicles on the road
(include the noises caused by engines from vehicles, gas emission, vehicle body
vibration, transmission and braking etc.), in which engines’ noise is the main
pollution source. The level of the noise is related to vehicle speed, vehicle flow,
vehicle type, road structure, road surface covering, road both sides buildings and
landform etc.
The relation between noise equivalent A sound level and vehicle speed when
various vehicles running refers to Table 3-9-5 as follows:
Table 3-9-5 The Relation Between Noise Equivalent A Sound Level And Vehicles
Speed Of Different Speed
Types Equivalent A sound level Li(dB)

88
Mid vehicle (3.5t—12t below) Lm=62.6+0.32V
Large vehicle (12t or more) Lh=77.2+0.18V
Note: the appropriate vehicle speed: 20~80km/h.
Table 3-9-6 The Li Value of different vehicles (dB) A
Types Equivalent A sound level Li(dB)

Mid vehicle (3.5t—12t below) 72.2 75.4 78.6
Large vehicle (12t or more) 82.6 84.4 86.2
Note: Acoustic source height: large and medium vehicles is 1.0m, small vehicle
takes 0.6m.
After the project, when different vehicles are running together, the level of noise
source intensity is impacted by many factors. The detail traffic noise on every road
section calculation result refers to the part of noise impact assessment in
operation stage.
3. Ground Rainwater Runoff
In this project, the major construction includes the matched newly built drainage
Subsurface Networks in Longzihu District to separately discharge of the rainwater
and sewage; after the newly built roads in operation, the rainwater runoff
generated on ground all enters into and collected by embedded rainwater
Subsurface Networks and then discharged into Longzi Lake or Baojiagou, which
impacts less to land surface water.

4 Alternative Analysis
4.1 COMPARISON BETWEEN WITH OR WITHOUT THE SAID PROJECT
In line with the survey of the current traffic, the area along the project line is the
farmland and residential houses. Lilou Road starts from Donghai Avenue and
ends at Huangshan Avenue; Today, Donghai Avenue is 30m wide concrete
motorway; Huangshan Avenue, a main road in urban plan is not under
construction and current one is still 6m wide farm earth-road . Fengandong Road
starts from High speed railway culvert and ends at Laoshan Road; today high
speed railway culvert has been completed and Laoshan Road is of urban
sub-main road and not constructed, the surrounding of which is farmland.
Nowadays, there are no city roads along the line of project and some villages
having “the narrow roads of “village to village” with limited traffic capacity. And
there are no Subsurface Networks distributed in the said area and rainwater and
sewage can not be collected together as a result to discharge them freely to
cause heavy water pollution to Longzi Lake and Huaihe River.
This project consist of infrastructures of two newly built main roads and the
supported drainage and illuminations; after the project, the traffic tension can be
relieved dramatically in Longzihu District, further release the traffic pressure of
Donghai Avenue to change totally the disorder and crowded traffic in eastern part
of the city; and meanwhile the urban rainwater and sewage in Longzihu District
can be collected effectively to render the positive function over the water quality of
Longzi Lake and Huaihe River. On the other hand, the branch road network
construction in high speed railway area will enhance the urban space extension
and land development and utilization in this area, improve the areal residents
traveling condition and living level, furnish a sound, advantageous and modern
urban traffic and social environments for city development and people’s living
quality. Therefore, the project construction prospect is promising.
4.2 Project Lines Direction Selection
In this project, two main roads (Lilou Road and Feng’andong Road) are the
planned ones in high speed railway area to be built up to meet the requirements of
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
90
city traffic plan (see fig. 2-4-2) , which, the only line choice has no other options.
4.3 Project Contents Comparison and Selection
The construction of roads and Subsurface Networks of Lilou Road and
Fengandong Road in Longzihu District has no other options, and in line with the
survey of the study group, the current urban road surface materials are modified
asphalt, cement and noise reducing etc. In project, through several materials
analysis, the decision of the road surface is made, and road surface materials
comparison refers to Table 4-3-1 as follows:

5 ENVIRONMENT IMPACT
ASSESSMENT AND POLLUTION
PREVENTION MEASURES IN
CONSTRUCTION PERIOD
5.1 SOCIAL ENVIRONMENT IMPACT ANALYSIS AND PREVENTION
MEASURES IN CONSTRUCTION PERIOD
This project mainly is two urban main roads and subsurface networks in Longzi
Lake District. The initial preparation period is long which consists of demolishing
of the original Subsurface Networks and houses etc. In construction period urban
roads will occupy some roads to impact city traffic and cause inconvenience to the
residents’ travel and work in the city.
5.1.1 Urban Traffic Impact Analysis and Prevention Measures
1. Urban Traffic Impact Analysis
(1) Interferences to current traffic will be impacted due to road and Subsurface
Networks constructions, the building task is being done without interruption the
current traffic and transport to fulfill the road network program. However, in the
building term, parts of road sections will incur traffic jam and crowding at peak
hours, especially in Donghai Avenue section in work rushing time. At this moment,
traffic management dept shall strengthen the control to divide the traffic flow with
the nearby road network to secure the residences’ life not to be impacted.
(2) In construction period, a large quantity of road building machineries and
transport vehicles will be used so as to increase the areal vehicle flow to cause a
certain impact over the urban traffic.
(3) The Relief Measures over Urban Traffic Impact
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
93
In order to reduce the mentioned and make road traffic smooth, the measure shall
be taken as follows:
(1) Before the task, the government shall make public notes to the residents
nearby to let them prepare for that;
(2) In order to minimize the impact to urban traffic, the division program for city
roads vehicle flows and routes shall be made in the construction period to
eliminate the traffic jam; sometimes, the urban traffic dept shall work closely with
other organizations to secure urban traffic smooth and normal running;
(3) The builder shall put “The Construction is being done in the Front”,
“Reduce Speed” and “Going around the other route” warning signs; on the
heaving traffic road section if necessary, special persons shall be dispatched to
direct the oncoming and leaving vehicles in building road sections;
(4) In order to facilitate the vehicles at night and reduce accidents, warning
sign lamps shall be installed in building road sections to guide the vehicles.
5.1.2 Analysis on the Impact to City Residents’ Life and Prevention
Measures
1. Analysis on the Impact to City Residents’ Life
(1) On the basis of the project impact over urban traffic, in the construction
period, the urban traffic is interfered to cause the traffic jam and crowding, and
therefore the temporary measures such as vehicle flow division and going around
shall be used, and public bus routes shall be also revised, which render the
inconvenience and impact to the travel, work and life of urban residents;
(2) In construction period, the noise emitted by diversified engineering
machineries and raised dust made by transport vehicles impact to a certain extent
the sensitive points of the residents nearby the planned line; the residents rest
and sleep will also be impacted if the building is done at night;
(3) In the construction period, the impacts over urban engineering and
telecommunication and power supply Subsurface Networks will be inevitable;
parts of Subsurface Networks and pipelines need to be demolished or moved,
which will impact and cause inconvenience to residents’ normal life to a certain
extent.
2. The Prevention Measures over the Impact of Urban Residents Life
(1) Various preparations shall be ready before project start, the contents
involved to the project such as road, power supply and telecommunication shall
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
94
be surveyed and studied carefully and cooperate with some related organizations
to determine the demolishment and resettlement plans and do well the
preparation over the urgent events to secure normal status of social life;
(2) The noisy equipment shall not work in rest time as much as possible,
especially at 10:00 night to 6: 00 next morning; good preparation shall be done
before work, including personals and materials etc, special persons shall
command the work trying to complete the task in shortest time to minimized the
noise impact to the people;
(3) In the task, low noisy equipment shall be used as many as possible and
eliminate heavily damaged machines; as to the building equipment used in
sensitive points, fixed schedule maintenance and service shall be carried out over
the machines to reduce the impact over the surrounding environment;
(4) In the project time, the vehicles flows on the roads where residents are
going in/out roads are denser than before near the residential area, therefore
warning illumination lamps and warning signs shall be clear and striking, the
contents, distinct to attract drivers attention;
(5) In the construction period, the power and water consumption are more
than the normal demands, builders shall inform the related departments ahead of
time to install the temporary lines and pipelines preparation job; as to the local
section where the said supplies are not sufficient, water/power lines modifications
shall be done in advance to avoid power and water interrupted to secure the
normal water /power supplies along the said line.
5.2 URBAN ECOLOGIC LANDSCAPE IMPACT ANALYSIS AND PREVENTIVE
MEASURES
5.2.1 Ecological Impact Analysis in construction period
In this project, there are two major new roads in urban planning program, it does
not occupy city green belt, therefore, the destruction to vegetation is basically
towards farmland green land and the environment impact is mainly from the spoil,
construction rubbles and transport vehicle in construction period.
(1) Poor treatment of project soil will occupy the farmland to reduce the
farmland per capita to a certain extent, meanwhile, since the population and their
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
95
consumption are keeping growing to deteriorate the pressure on the remained
farmland to cause the contradiction between people and cropland and further to
deteriorate the ecologic and environment problems.
On the basis of the earthwork for two newly built roads, the project’s digging
earthwork is 1333059m3, filling earthwork is 1267335m3; the earthwork excavated
will be reused for road fill in the project, some surplus one will be used for the fill
for nearby Gaotiedong Road and Xueyuan Road; therefore this project will not
take the earthwork taking and earthwork damping yards, and accordingly the
impact over the land utilization is slight.
Generally the projected project located at urban region belongs to urban
construction land use. The vegetation destroyed in this program will be recovered
gradually and therefore the vegetation in the assessed area will not be impacted
too much.
(2) The projected main engineering is inside the city, the land is flat,
engineering is the high filling and less deep digging, basically there is not soil
erosion; however, some impacts would remain, since the building materials such
as earthwork, sand/stone materials, cement and clay, and some temporary piling
of spoil and discarded materials will bring forth a certain impact over urban
ecology, especially the poor protection and pilling of the spoil under heavy
rainwater scouring will block roads’ drainage pipeline, impacting urban traffic and
city beautification.
(3) In construction period, the transport of earthwork, sand/stone materials
and cement will emit a large amount of raised dust if the protection measure is not
well done as a result, the road surfaces, green belts and residential areas of both
roadsides where the transport vehicles are traveling will cause dust pollution and
impact urban environmental hygiene to a certain extent.
5.2.2. The Analysis on the Engineering Impact over Urban Landscape
In this project, the impacts over the surrounding landscape are mainly in the fields
as follows:
(1) In the demolishing and Subsurface Networks demolishing and
reconstruction, it will impact local urban appearance and beautification to a certain
extent, but it is temporary, and it will end after project. On the other hand, through
the reconstruction over urban greening and shantytowns, the urban beautification
will be enhanced in the future.
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
96
(2) In the project of foundation and earthwork excavation, the pilling of
earthwork and building materials, especially the temporary piling of spoil and
rubbles will impact urban hygiene and landscape.
(3) In the project, some disorder piling and parking of temporary building
materials and engineering equipment will bring forth some inharmonious impacts
and negative factors to the surrounding landscapes;
(4) In the project, some isolating measures such as the railing, fences and
coverings will be built up in the process of new roads construction and widening,
which will bring forth certain destruction over urban landscape.
(5) In the project, the noise, raised dust, waste gas, engineering rubbles and
engineering water drainage from engineering equipment and temporary work
camps will render pollution over the surroundings; due to the construction
interference, the stores and shops on both built roadsides will be impacted and
urban landscape will be destroyed to a certain extent.
5.2.3 Landscape Protection Measures in Construction Period
In the project task, attention should be paid to the ecologic landscape, especially
the points as follows:
(1) Re-plantation protection shall be done over the grass, flows and trees in
the middle and sides of roads and it is not necessary to destroy all the said and
grow all the new ones.
(2) In this project, building work shall be done inside redlines as much as
possible, the piled earth and materials shall not enter into the land field nearby.
(3) In this project, the demolishment will form a “ruins”, demolishing work shall
be carried out in plots in sequence to avoid poor landscape and view blocked
along the projected lines; it is possible to install protective plates (with the
materials of wood, glass or steel sheet etc.) as fences to minimize the pollution to
landscape.
(4) Do well the reasonable dispatches for digging and filling earthwork to do
the ecologic recovering over the spoil yard to minimize the impact to it; not to do
excavation in raining season to prevent rainwater from eroding the soil, polluting
water body and blocking drainage pipelines.
(5) For selling the spoil to outside buyer, a contract shall be signed with the
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
97
said for ecologic recovering.
(6) On the basis of meet the requirements of building task, efforts shall be
made to reduce the occupied land area and manage construction schedule
reasonably. After the task, clear the site, retreat from the occupied area and
resume the original roads and greening in time.
(7) Arrangement the job schedule reasonably and void the work in raining
season to minimize soil erosion as much as possible.
5.2.4 Ecological Recovering Measures in Construction Site
1. Ecologic Resources Protection
(1) Reasonably plan to do well longitudinal transport of earthwork to minimize
temporary occupied land;
(2) Do well land compensation for the occupied land, as for the occupied crop
field, do well reasonable compensation, old field reclamation and new field
reclamation in line with state or local standard.
(3) Strengthen the education over the builders’ environment protection sense
to protection natural resources; if it is needed for the project, the land surface of
30cm shall be maintained when the excavation is done and refilled them after
project to minimize the impact over farming.
(4) Arrange the work schedule reasonably to minimize the building areas and
shorten temporary land occupation time and recover the vegetation and
reclamation as soon as possible after the work completed.
(5) The engineering spoil shall be removed in time to avoid soil erosion in
raining season and the spoil can be used for the fill earthwork in road building.
(6) Pipelines shall be laid along roads to avoid going through the green field
and trees on roadsides; if it needs going through, the related compensation
measure shall be make after project.
2. Ecological Recovering Measures
(1) In line with urban general plan of the city, temporary land occupation and
shortening occupying time shall be carried out in road building and its supporting
construction and the covered soil shall be resumed to recover the vegetation in
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
98
time after the end of project.
(2) No spoil and waste materials shall be dumped without discipline and the
dumping shall be dumped in fixed place, transported out in time to minimize
pollution to soil.
(3) Green Land Recovering and Compensation Measures
① In order to reduce vegetation destruction, roads extension shall be laid out
in terms of the area general plan, at the same time, the infrastructure and ecologic
construction shall be also carried out. Therefore, it impacts the original vegetation
to a certain extent, meanwhile, related compensation is done, which render the
limited impact to the aforesaid.
② Before occupying the land temporarily, first remove the surface soil to put it
in a place together, after the project, the original surface soil shall be recovered to
resume the original vegetation and the roads greening will be also considered.
(4) Proposal of Road Network Greening and Plants Growing
① The project shall be in line with the greening requirements of urban
general planning, the specific individual design on every road section shall be
done in terms of the requirements such as road basement along the route, road
section’s surroundings character, road landscape and inducing visual road width
and traffic facilities.
② Apart from the road base protection consideration on both roadsides
greening, road network landscape and environment friendly function shall be also
thought such as soil/water conservation, noise reduction, air pollution prevention
etc. If condition is permitted, cooperation shall be done with local gardening
department to uniform the green belts.
③ In order to reach 90% or more survive rate of the vegetation, the plants
which are appropriate for local natural conditions shall be planted such as arbors,
shrubs and grassland. The middle part in the road is separated with fallen leaf
shrubs, one row on both sides with 2m interval, such as evergreen trees etc.;
trees of pedestrian pavements will use fallen leaf trees (poplar and camphor tree)
mixed with fallen leaf shrub, the fallen leaf tree is 8m interval with two fallen leaf
shrub in between with 2m interval, i.e. every shrub is planted at 3rd meters and 5th
meters.

5.3 NOISE IMPACT ANALYSIS IN CONSTRUCTION PERIOD AND
MEASURES
5.3.1 Assessment Scope and Standard
In terms of road construction environment impact assessment criterion, highway
or road building noise impact assessment scope means 200m on both roadsides.
Since this projected undertaking is urban road, there are more sensitive points on
within 200m of both roadsides, there the importance of this assessment is the
impact over the sensitive points when the building work is being carried out, its
assessment standard adopts (GB12523-90) of “Noise Standard in Building Sites”.
And the limit value of the standard for the building noise impact under different
stage in building area refers to Table 1-6-1.
5.3.2 Constructional Equipment Noise Level Survey
The noise in construction period mainly comes from that of engineering
machineries and transport vehicles. In line with the actual investigation and
comparison, the impact sources over environment are the equipment such as
dozers, loaders, road rollers, excavators, auto unloading vehicles and road
pavers. The max test value of the above machines in the operation period refers
to Table 5-3-1.

5.3.3 Noise Forecast Result in Construction period and Impact Analysis
(1) Noise Forecast Result in Construction period
The construction noise source is regarded as point acoustic source. In terms of
the point acoustic source noise attenuation mode, the noise value with the
different distance to noise source can be calculated, and the forecast mode is as
follows:
Lp=Lpo-20lg(r/r0)-ΔL
In the equation: Lp— distance to noise source r(m) acoustic pressure level,
dB(A);
Lpo—distance to noise source r0(m) acoustic pressure level,dB(A);
r—distance to noise source,m;
r0—distance to noise source test, m;
ΔL— various attenuation value (except for diffuse attenuation ),dB(A). Open air noise ΔL takes
zero.

Known from the calculation, the environment impact scope of the noise from
engineering equipment without any blocking is 35m in daytime and 281m at night.
Out of the distance, it can meet the requirements of “Noise Limit Value in
Construction Working Sites” (GB12523-90).
(2) Construction Noise Environment Impact Analysis
① If single machine is used, the building site out of 35m in daytime is able to
reach the requirements of 75dB (A) of “Noise Limit Value in Construction Working
Sites” (GB12523-90), and the building sites out of 281m at night is able to reach
the requirements of 55dB (A) of “Noise Limit Value in Construction Working Sites”
(GB12523-90). However, in the actual operation, sometimes more machines are
working together and the noise impact limit will be more.
② The engineering noise sensitive points are averagely 5~30m distance
scope, which impact stronger to surroundings. This projected acoustic protection
is basically within 30m along the project redline, therefore, in daytime, it will
impact to a certain extent to the first row houses on both roadsides such as
residence and school and hospital; at night, it impact much to the residents sleep,
thus strict measures shall be taken to minimize the noise in building site to reach
environment protection targets.
③ As the project completed, such a noise will not exist anymore, the building
noise is temporary and in short period.
5.3.4 The Prevention Measures and Proposal of Construction period Noise
Impact
Known from the predication, most of the noise in this projected exceeds the
requirements of “Noise Standard in Building Sites”, although the noise in working
can not be avoided, in order to reduce the noise impact to the surroundings, the
projects contractor and builders shall normalize their activities in line with the
regulations of “Environmental Noise Pollution Prevention and Treatment Rules of
People’s Republic of China” and “Environment Protection Ordinances of Anhui
Province”. Moreover, the contractors are recommended to take measures to the
aspects to minimize the noise impact as follows:
① High noise and high vibration equipment are forbidden to work at noon and
night period, the builders shall employ low noisy machineries or those with sound
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
102
isolation and silencer.
② Arrange the working time reasonably, under normal situation, the noise in
daytime impacts less to residents’ normal life, more to them at night. Therefore,
reasonable management shall be done to avoid the impact to their rest and sleep
in that period of time.
③ Arrange working sites reasonably, high noisy working sites shall be far
away from noise sensitive point, as for some serious impact sites, temporary
sound insulation and coverings shall be done, and some temporary labor camps
can be set up to substitute noise insulation wall; earthwork shall be done by more
machine working at same time to shorten the impacted time; the fixed noise
sources in working sites can be also concentrated to reduce vibration interference
range. Before the work is done nearby the residential areas, temporary sound
barriers measure shall be taken to reduce the noise.
④ In terms of regulation from rules of environment noise pollution prevention
and treatment of PRC, the builders shall apologize or compensate the
organizations or individuals in case some noise reduction measures taken can
not reach the values stipulated in the regulation.
5.4 IMPACT ANALYSIS AND TREATMENT MEASURE OF ENVIRONMENT
AIR QUALITY IN PROJECT PERIOD
5.4.1 Environment Air Impact Analysis in Project Period
1. Raised Dust of Vehicle Running
In the construction, the raised dust amount caused by vehicle running accounts
for more than 60%, which can be calculated with the following equation if it is
under fully dry condition:
75.085.0
5.08.65123.0
PWVQ
In the equation:Q— vehicle running raised dust, kg/km. vehicle;
V— vehicle speed, km/hr;
W— vehicle load capacity, ton;
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
103
P— road surface dust amount,kg/m2.
Seen from above, under the same condition, the more the vehicle speed is, the more the raised dust will be; under the same vehicles speed, the dirtier the road surface, the more the raised dust will be. Therefore, it is an effective measure to limit vehicles running speed and to keep road surface clean.
In construction period, the vehicle running road surface shall be watered to control the raised dust, 4~5 times a day to reduce 70% raised dust, in Table 5-4-1 is the test result of building site raised dust controlled with watering. Therefore 4~5 times watering per day, the raised dust in working site can be controlled so as to reduce TSP pollution down to 20~50m range.

2. The Raised Dust in Piling Yard
The raised dust of road construction period’s another source is wind force raised dust in open air piling yard and open site. Due to the construction need, some materials need to be stacked in open air, the land surface soil in building site after excavation is stacked in open air temporarily, and it will generate a large amount of raised dust under dry and windy situation. The raised dust can be calculated with the experience equation of piling yard raised dust.
WeVVQ 023.13
0501.2 In the equation:Q— amount of raised dust,kg/ton. year;
V50— wind speed with distance 50m to ground, m/s;
V0— dust raising wind speed,m/s;
W— dust granule water content,%.
Dust raising wind velocity relates to dust granule diameter and water content therefore, reduction of open air piling and keeping a certain water contents and reduction of the land exposed are the effective measure to control wind force dust rising. The dust spreading and dilution relate to the meteorological condition such as wind velocity, and also to the falling velocity of dust itself. The falling velocity of different diameter dust granules refers to Table 5-4-2. Seen from the table, dust’s falling velocity grows with the dust granule size increases; when the granule size is 250 micron, the falling velocity is 1.005m/s, thus it can be regarded as when dust granule size is more than 250micron, the major influence range is in the near range of dust raising downwind, the real impact to exterior environment is the smaller granule size dust.

3. Dust Rising due to Mixing
It is shown in road building soil/lime mixing site monitoring information that when
the road building materials is under mixing, TSP hour concentration at 50m place
is less than 1.0mg/m3. The TSP hour concentration nearby 5m in downwind in the
piling material yard’s soil/lime mixing station is 8.1mg/ m3; to the distance of 100m,
the concentration is 1.65mg/ m3; to the distance of 150m, there is no impact.
Therefore, the soil/lime mixed material for the project shall be purchased from
concentrative mixing enterprise or such a mixing station shall be set up 150m
away from the sensitive point of residences to minimize the raised dust impact to
the environment along the projected line.
Generally, the construction period is shorter compared with operation term and
the impact is temporary and can be reversed, but certain pollution will be caused
in case strict management is not carried out. It is highly demanded that the
mentioned measures shall be done as to stress civilized building activity, the
environment friendly requirements, formulation of job responsibility and obeying
environment department supervision and management.
5.4.2 Environment Air Pollution Preventive Measure in Construction
Period
There are some residential points in this projected both roadsides whose
distances are less than 150m, thus, the dust produced in the working will impact
the residents in downwind and other sensitive targets, especially the
constructional vehicles are running on the road where the base layer is completed
and the surface layer is not paved as a result to raise a large amount of dust to
cause severe impact to the air surroundings in case no measures are taken in the
process of road building, materials transport and material mixing. In order to
minimize the impact to the surrounding environment in project construction period,
the protective measures are highly recommended as follows:
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
105
(1) In the construction period, the dust will be raised due to old buildings
demolishment, land leveling, piling, digging, materials transport, load and unload
and mixing as well, especially it is more severe when it is the dry weather. In the
building site, watering to control dust shall be done as 4~5 times daily to reduce
the raised dust at approx 70%;
(2) In the building activity, the road base shall be compacted in time and take
care to water the soil to control dust; when transport bulk dust contented materials,
those shall be covered as mush as possible; the overload vehicles for transporting
sand/stone shall be limited to avoid the sifting and leaking to reduce dust
pollution;
(3) The powder materials such as cement and lime shall be packed in barrel
and bag and bulk transport is forbidden, the piling shall be covered with paulin.
The major roads in and out of the sand/stone yard and construction sites shall be
equipped with tank car to water them in time to absorb the raising dust generated
by sand and stone materials and the covering rate shall be 100%;
(4) Building site shall be installed with fencing for sand and soil which shall be
fixed with non-woven fabric and moreover, interception dikes and sand ditches
shall be also laid out and refill them after end of project;
(5) In order to resume road surface traffic, avoid traffic jam and reduce the
impact to surrounding air pollution by the raising dust generated by excavation,
construction being done in peak transport time shall be avoided in building activity,
pipeline laying, be done in sections and refilling, be done as soon as possible;
(6) In case the building work is done nearby the sensitive points such as
residential areas, dust raising job shall be done well to take effective measures,
increase watering times to minimize the direct raising dust impact over the
residents.
5.5 WATER IMPACT ANALYSIS AND PROTECTIVE
MEASURES IN CONSTRUCTION PERIOD
5.5.1 Waste Pollution in Construction period
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
106
The construction period sewage comes mainly from constructional and builders’
living waste water. In case this waste water is directly discharged without
treatment, it will impact the nearby canals to a certain extent. Therefore at the
concentrated builder camps, temporary living sewage treatment (digestion tank)
shall be built. Normal digestion tank is able to eliminate 30~40%BOD5 and
50%CODcr, the sewage after digestion tank treatment can be used as crop
fertilizer. The untreated sewage in building site is forbidden to drain into nearby
water body to reduce the impact to water environment. The sewage containing oil
shall be first treated with oil insulation and then discharged into digestion tank.
5.5.2 Sewage Protective Measures in Construction period
In construction period, builders shall design the sewage discharge to forbid the
free discharge to cause environment pollution, and the detail measures are as
follows:
(1) The building sewage contains a large amount of earth, sand and oils, the
direct drainage into canal will cause water pollution and into farm land will cause
soil pollution, therefore, building waste water shall not be discharged into canal or
urban Subsurface Networks. The building waste water after settlement can be
reclaimed for watering raising dust; living waste water after oil isolation and
digestion tank treatment can be used as fertilizer for the crops in nearby village.
(2) The project’s builder shall treat the slurry by means of simple filtering and
settlement, the direct emission without treatment is forbidden; the contractor shall
strengthen the management to secure civilized building activities.
(3) As for the living refuse, building rubbles, service rubbish, since direct
discharge into water body will cause pollution, therefore the recycling, sorting,
storing and treating shall be done, of which some can be reused or sold out; if
there are wastes materials such as papers, wooden materials, metal and glass,
they can be recycled, those can not be reused anymore shall be delivered to
urban environmental dept for non-hazardous treatment such as burning, deep
burying or piling etc.
5.6 THE IMPACT ANALYSIS OF SOLID SUBSTANCES IN CONSTRUCTION
PERIOD
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
107
5.6.1 Impact Analysis of Solid Substances in Construction period
In construction period, a large amount of residual earth, rubbles (demolished from
the old houses), the remained mud from land surface excavation and waste
materials in the building will exist, which will impact the traffic and deteriorate
environment if not treated well. In the process of transport, if the clean transport is
not stressed, the released mud and soil will be spread all over on the streets and
roads to affect city hygiene and traffic.
The discarded earth if not well treated will impact traffic and pollute surroundings.
If the transport vehicles for carrying the discarded dug earth traveling on the roads
inside the city do not only increase the vehicle flow on that area, but also cause
the traffic jam, and the spread and leaked earth will also impact urban cleanness.
If the discarded earth which is not piled and dumped in order, it will cause soil
erosion in case there is storm to cause rainwater scouring. In the building sites
inside city, the rainwater runoff will enter into urban drainage system in “yellow
mud water” and will block the drainage ditch if it is settled. Meanwhile, the slurry
with the pollutants such as cement and greasy dirt from working sites entering into
water body will cause water pollution.
This project area belongs to plain area, the total earthwork amounts to
499997.2m3 for the said road building in that period including 176230.175m3 filled
earthwork, 323767.025.2m3 excavation earthwork. There is one temporary
discarded earth yard for the major project, which is located at southeast side of
the intersection between Lilou Road and Fengandong Road – the land for
ecologic park in high speed railway area in the future. The excavation earthwork
generated in the project will be reused in the fill for the road building and the
surplus will be all used in the fills of building of Gaotiedong Road, Xueyuan Road
and the planned ecologic park.
5.6.2 Solid Waste Materials Preventive Measures in Construction period
In order to reduce the environment due to discarded earth piling and its transport,
the measures are proposed as follows:
(1) The builders shall go through the formalities of dumping of residual slurry
and brick rubbish to unload them in appointed place when the said formalities are
managed.
(2) The materials transport of the vehicles shall be away from the traffic peak
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
108
time of sensitive points. The transport shall be limited in the regulated time
intervals and travel on determined roads. When vehicles transport the bulk and
discarded materials, appropriate load shall be secured and covered with cloth;
before work, the vehicles out surfaces shall be cleaned with water to guarantee
there is no earth and dust released on the roads.
(3) The dust-raising wastes shall be treated as piling method isolated with
fencing; the wastes of block shapes as brick and title and of granule shape can be
treated with normal piling method, however, they shall be transported to the
assigned solid wastes dumping yard finally.
(4) Building activity shall be carried out in total sealed way to control the
pollution impact in the range of worksite in the project period to minimize the
impact to the environment.
5.7 SOIL EROSION PREVENTION PLAN IN WORKSITE
1. Preventive and Management Plan
① Land surface soil clearing work shall be done in non windy and raining
days so as to avoid severe soil erosion. The green field for temporary piling shall
be covered to eliminate the occurrence of wind erosion and rainfall erosion. When
the surface soil is peeled according to the schedule, the digging and destroy large
area of land surface and vegetation shall be avoided, since it will cause large area
land surface uncovered to lead to soil erosion if the next work sequence can not
followed in time.
② After the end of soil projects, next job sequence and the related protection
measure shall be introduced and done. The same way, after the site work is
fulfilled, carrying out land treatment and vegetation recovering shall be followed to
reduce soil erosion in time and control the hazard effectively.
③ Reasonable management shall be carried out in building activities, the
fiber web employed in temporary projects can be used repeatedly according to
actual engineering and working schedule to reduce the costs of soil erosion and
can be also as one of the calculation base for fiber web material investment in the
plan.
④ The living sewage and refuse of builders living areas shall be well
managed and not be discharged directly into nearby water body.
⑤ The person who is responsible for soil erosion in building site shall
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
109
coordinate and arrange work sequences, the job which is hazardous to the soil
erosion shall be treated with the related measures before the hazards occurrence.
2. Vegetation Planting and Fostering Measures
The measures for plants shall be stressed in terms of routine maintenance and
fostering, especially in the initial project period, such activities are even more
important, the main fostering and maintenance are: watering in time in line with
the demand to secure nursery stock survival rate; check periodically the nursery
stock growing conditions to replant if some do not survive; the management shall
also be stressed on the area where the vegetation is growing and fostered.
① Nursery Stock Temporary and Field Transplantations
The nursery stocks which can not be planted in time in several days after
delivered into site or those remained after plantation shall be treated as temporary
transplantation. It mainly involved the plants with roots wrapped with soil and the
trees crown can be compacted and baled to put them together in compact way.
Afterwards, the soil balls are covered with a layer of earth to fill the gaps in the
root balls; water the balls and crowns evenly to let the surface soaked with water
and keep them well in humidity.
The nursery stock after pruning can be done in field transplantation and its
position shall be in line with the design. The method is: put the nursery stock soil
ball into the center of the pit gently, hold it vertically and then fill with soil in layers,
the roots of the trees shall well extend, each soil layer shall be compacted until the
pit is full with soil; after that, check and make it vertical if not, and finally do the
supporting.
② Planting Hole Digging
Planting holes are generally circular shape and the bottom and top are same in
size. The size of the hole depends on the nursery stock root ball dimension in a
bid to let the roots spreading out fully.
Arbor adopts the planting in pit, the distance between two plants depend on the
design; the multiple year stout seedlings are planted in spring or raining season,
compact the soil after growing, then watering; shrubs are planted also in pits in
spring or raining season, the distance between two plants depend on the design,
the planting shall not be too deep, soil shall be compacted, then water them
thoroughly once; the shrub and grass seeds shall be sowed in spring and raining
season with the method of sowing in lines or broadcast sowing; before sowing,
the field shall be treated and leveled, then broadcast sowing of the seeds, water
them to keep humid to secure their coming out normally.
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
110
③ Maintenance and Management
The said plants shall be cared in routine maintenance and fostering, especially in
the initial project period, it is most important as to the nursery and management.
The major fostering measures are: water in need periodically to secure its survival
rate; check the seeding growing condition in fixed time, to replant if some do not
survive; the management shall be stressed on the area where the vegetation is
growing and fostered, and the chopping and herding without the legal permit are
forbidden .
Some trees and seeding to be planted in mid-post period in the construction
period whose leaves are growing out, anti-transpirant can be spread to control the
self transpirant capacity to enhance their survival rate.
Some bared roots nursery stocks shall be planted after roots trimming, and the
roots shall be dipped with 3% concentration ABT Transplantone #1, which is able
to improve the roots growing and survival rate.

6. ENVIRONMENT IMPACT
PREDICATION AND ASSESSMENT IN
OPERATION PERIOD
6.1 SOCIAL ENVIRONMENT IMPACT ANALYSIS
6.1.1 Positive Impact Analysis
The area involved in this project is dense residential areas (such as Shanwang
village, Huangxiang village, Lilou village and Pingtangwang etc.). In the said area,
the roads are generally poor, most of them are natural roads without the public
bus and it is quite inconvenient for the residents’ travel. This project, on one hand,
it will enhance roads quality and increase the public bus routes to improve the
local residents travel, on the other hand, better their living quality by means of old
houses demolishment and resettlement, and drive the regional supporting
facilities improved and vitalize the local economy.
The social benefits after the project will be the aspects as follows:
(1) Improve urban traffic state and perfect urban traffic system
This project will raise new requirements for the infrastructures such as urban
traffic, logistics and parking area. After the end of the project, the peoples’ travel
will be even easier and it will play a positive role to not only private car quantity
increase but also the traffic state improvement for public bus service. Furthermore,
the urban traffic improvement and road network perfection will function in radiation
action to surroundings so as to improve the trans-city transport and strengthen the
co-development among the trans-city groups to highlight the sound group
advantages.
Acceleration of traffic development and building of the comprehensive, complete
and opening traffic network is the necessary road for city expansion. The building
of urban road network will drive city belt extension, impel surrounding systems
quick growing, perfect urban system and to encircle the area for future
development as a result to accelerate modern urbanization.
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
112
At the same time to develop traffic career, it will also strengthen the central city’s
impelling force to radiate the other cities and areas, quicken urbanization, play a
significant role as a central city to impel the development of other regions.
(2) Beautifying Urban Appearance
At the same of building new roads in this project, the planting trees on both
roadsides, growing new glass land at isolation belts and other places do not only
beautify the surroundings but also improve the ecologic environment. Moreover,
in the process of road expansions, the residents houses will be demolished and
resettled in the areas along the roadsides, and the facilities such as water supply,
power supply, steam supply and drainage system shall be all reformed, which will
beautify the environment to a great extent.
(3) Bettering living condition and enhancing people’s living quality
Real estate demands significantly on traffic. The traffic improvement will vitalize
people’s demands for the residents in that area, which raise the real estate
regional economic value and social function assessments. The said area has
satisfied traffic accessibility. The living quarters with perfect transport facilities will
be given high assessment by the consumers and the value of the quarter is higher
in value. After the roads conditions are improved, the real estate along the roads
will increase their value, therefore people’s living condition will be improved
greatly.
In one word, after the project, the road network accessibility in Longzihu District of
Bengbu will be prominently improved, the city environment is beautified, urban
functions are enhanced in all ways, residents travel is benefited, travel time is
saved; therefore, the land price along the lines will grow up and land price will be
actually realized; it will impel the related urban industries, real estate, commerce,
service and IT etc. to improve economic construction; it will better investment
environment and tourism to a great extent. Therefore, it is universally thought that
this project is a people profitable undertaking to benefit the society, economy and
environment.
6.1.2 Negative Impact Analysis
Some negative impacts will also be brought after the roads built and traffic
condition improved since the vehicle speed and flow increase as follows:
(1) Inconvenience in life due to community division
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
113
Since new road routes put into service and road widening, the original
communities will be divided to form two or more sectors but the supporting
facilities for production, living and entertaining are also separated. Since the
original earth roads are narrow and have less traffic, the local residents are
accustomed to cross those roads freely and safely, as the road widened and
vehicle flow increases, the local residents encounter the difficulty such as road
crossing for their life, production and study activities, sometimes they just cross
nearby; furthermore, in the middle of roads, the green belt, isolation belt and
middle isolation fencing are installed to prevent pedestrians from crossing, it will
also increase their travel time and distance – the inconvenience. Therefore, some
zebra crossings, traffic signals and overpasses in some road sections should be
arranged in line with the peoples’ need and the requirements of road design to
meet the demands of residents.
(2) Impact to Traffic Safety
Another prominent impact is the traffic safety risk going up at the same time of
traffic improvement due to vehicle speed and flow increase. It can be considered
from two aspects, one is the risky in vertical crossing and another is longitudinal
risky.
The lateral risk comes from road crossing. The division of communities, especially
some areas where there are residences, commercial regions, or mixed
commercial/residence and schools and hospitals, which are close to people lives,
where there are more crossings and travels of the people to cause the
complicated mixing of pedestrians and vehicles as a result the increase of risky
factors. In those places, traffic signal lamps, zebra crossings, overpasses and
culverts shall be installed, especially the time when students going or leaving
schools will cause pedestrians crowding and occupying the vehicle road to lead to
hidden safety risk.
The longitudinal risk comes from the traffic risks between vehicle, pedestrians and
vehicles during vehicles’ traveling on road. Since different vehicles have unlike
speed and there are different driving demands between motor vehicles and
non-motor vehicles, public bus and taxi, the traffic risk will also occur in case
those factors are not fully considered and studied in the process of road design,
the roads are not widened in line with the actual traffic flow demand. We propose
that the fast and slow lanes and the lanes of public bus and other vehicles can be
separated, and non-motor vehicle lanes and pedestrian pavements of reasonable
flow capacity are designed in compliance with actual traffic requirements to
minimize the traffic risks to a great extent.

6.2 Impacts Analysis of Urban Ecologic Environment and Landscape
Urban landscape is the overall complex of natural view, constructional view and
cultural view; urban landscape requires harmonious relationship between natural
view, city construction, urban resource development, economic development and
ecologic protection to let city develop in sequence, solve city ecologic sickness
and form urban ecologic system positive cycle.
After the project, more greening design and reasonable arrangement will be made
on newly built roads which function in the overall environment effects such as
road surface protection, soil erosion reduction, traffic dust and noise decrease
and optimized road micro climate so as to improve the landscapes along the
roads and beautify the roads view.
(1) Urban view is the first peoples’ feeling gained when they are doing
activities along the roads. This project is the building of urban main roads and
their greening matters much to urban landscape and urban view, furthermore,
most of the undertaking is at the city region, where there are more buildings on
both roadsides where more buildings cause the roads seem narrow, the greening
barrier function will reduce the sense of depression by the constructions. From the
view of colors, the blue sky and green trees are the calm colors to let people
mood calm.
(2) Plants is one of the important factors in urban beauty space, the colorful
streets view can be formed with the multiple factors of special lines, shaped colors
and seasonable changes of plants added with diversified tree varieties, different
enjoying periods and formations to obtain striking features, and the road lamps,
parterres and rubbish tanks will also help the beautifying.
(3) Roads green land is able to beautify urban landscape and support
roadsides construction art; meanwhile, it will also meet the demands longing for
the green land form the residents living in the high residential buildings.
Generally to say, the post project’s reasonable greening configuration will
strengthen urban beauty, beautify urban appearance and give people the feeling
of comfortableness.

6.3.2 Environment Air Impact Predication
1. Environment Impact Predication of Roads
(1) Predication of emission source intensity of every road section air pollutant
The process of motor vehicles exhausted pollutants are very complicated and
related to diversified factors, therefore it is difficult and complicated to determine
the vehicle tail gas exhaust index. This assessment adopts the method of EPA
and MOBILES models from USA. In line with engineering analysis, the motor
vehicles exhausted tail gas source intensity in different year refers to Table 6-3-4
as follows:
Table 6-3-4 Motor Vehicle Tail Gas Exhaust Source Intensity on Roads

(2) Predication Factors
-- Predication factors
Select the major pollutants emission factors of vehicles: CO, NOX;
-- Predication time interval
The time interval is from 2014 ~2021;
-- Assessment Standard
The predicative source intensity is pollutants emission volume in peak time
hour, therefore, the test is done in hours and however there is no NOX standard,
the predication range is given as CO10mg/m3.
-- Predication Range
In compliance with the character of road air pollutants, the pollutant
concentration of 200m down wind in the evaluated road shoulder is tested;
-- Meteorological condition Selection
Select the normal yearly average wind velocity and static small wind
meteorological condition as predication conditions, the predicated wind direction
takes the wind direction vertical to road surface.
-- Diffuse Model Selection
AIES Environmental Impact Assessment

can be calculated and added in line with noise status monitoring to get every
sensitive point’s predicative value after the project. Since the current noise state is
of typical feature, all the environment project targets’ noise levels can be known
on the basis of predicative value of monitoring point.
Known from Table 6-4-3, after the project, the sensitive point in daytime in 2014
can be up to the related standard; at night, all the other sensitive point are out of
the standard limit except for in Huangxiang Village at night, the exceeding range
is 3.14~5.08dB (A); in 2021, all the other sensitive point are out of the standard
limit except for Huangxiang Village in daytime, the exceeding range is
1.01~2.31dB (A); it means that all the sensitive points exceed the standard at
night, the exceeding range is 0.94~7.83dB (A).
2. Traffic Noise Impact Analysis and Assessment
The area to a certain distance to both urban main roadsides of this project shall
carry out 4a category standard of “Acoustic Environment Quality Standard”
(GB3096-2008) except for noise sensitive point; in case the main roadsides’
constructions are multiple floor buildings of more than 3 floors, the area of 1st row
building facing roadside shall execute 4a category standard, but the 1st row
building on roadsides’ sensitive point shall execute 2 category standard; in case
the main roadsides’ constructions are less than 3 floors, the area of a certain
distance out of redline shall execute 4a category standard. If the adjacent area is
1st category area, the distance is 45m; if the adjacent area is 2nd category area,
the distance is 35m; if the adjacent area is 3rd category area, the distance is 25m.
Therefore, the areas on both Lilou Road and Fengandong Road are mainly the
open ground of the buildings of less than 3 floors, those on both roadsides within
35m to road’s redline shall carry out 4a category standard being.
Known from noise contour map (Fig. 6-4-1~6-4-4), after the project being built,
that within 30m to both roadsides’ redlines will be up to the standard requirements
of 70dB (A) and 55dB (A). After the end of the project, the noise impact in 2021
will be more than that in 2014.
As to the acoustic environment sensitive targets of the project along the lines, the
noise reduction measures shall be taken by means of installing ventilation/sound

127
isolation windows; after the mentioned measure, the room acoustic environment
noise of acoustic sensitive targets will be up to the related standard requirements.
6.5 IMPACT ENVIRONMENT ANALYSIS OF WATER
In this project operation period, the waste water is mainly from the land surface
rainwater runoff on road surface and finally drained into urban engineering
rainwater Subsurface Networks to impact little to water bodies surroundings.
6.6 IMPACT ANALYSIS OF ECOLOGIC ENVIRONMENT
The urban road construction needs to occupy land as a result to change land
nature and cut the original and complete ecologic space, therefore it is an
undertaking impacts much toward ecologic environment. In the process of project,
especially the building activities, including those of road surfaces, culverts,
subways, materials yards and the movement of people and vehicles will arouse
land surface interference and destruction to impact natural ecological
environment balance. On the basis of the impacts to ecological environment, the
project’s three stages can be classified into the stages of design, building and
operation, in which building stage impact much.
6.6.1 Impact of Areal Natural Ecological Environment Integrity
Because of the road building activities, the original and complete landscapes tend
to be broken up into pieces to cause landscape ecological function deteriorated.
Since the areas along roads are mainly crop field ecological system without
natural ecological system generally, the projected roads impact less to complete
ecological environment integrity. The road design guarantees land ecological
environment integrity to a great extent, relieve the impact to the wild animals and
plants surroundings. Meanwhile, there are not large wide animals in the said area;
some small animals demand less for their habitats, therefore the road division
impacts less to animals’ distribution and activities.
6.6.2 Analysis on Land Occupation
This project totals 25 hectares occupied area, 23.9483 hectares permanent
occupied areas and 1.0517 hectares temporary occupied land. The project has
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
128
been listed into urban high speed railway general plan, and the land requisition
plan has been prepared. The land needed by this plan will be expropriated by BIG
uniformly. The permanent land use for this project refers to Table 6-6-1.

Seen from the Table 6-6-1, the project permanent occupied land is the rice filed
not the wood land, it impacts less the city forestry but impacts some to farmland
but the amount is not so much.
6.6.3 Impact Assessment on Biodiversity
1. Areal Vegetation Impact Analysis
(1) Impact Analysis of Wild and Rare Plants
From the information consultation, there is no plant listed into state I class rare
trees and old trees category, and even large trees in the evaluated region are
found neither. Limited by time and conditions, we can not exclude that some trees
mentioned above, in case they are found in the process of building, the
construction shall be stopped for the protection and inform the contractor and
experts for proper management.
(2) Areal Vegetation Diversity Analysis
The most great change occurs along the built road lines in the process of road
building, the first is land requisition to destroy the green vegetation; the second is
the vegetation is destroyed due to different earth excavation and unlike road
foundation, e.g. in the fill road section, the vegetation damage is destructive due
to rolling and pressing by engineering machineries, transport vehicles and
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
129
builders operation. Generally, the natural vegetation can not be recovered in
permanent road building, only part of the areal (slope protection) vegetation can
be resumed; the natural vegetation in temporary occupied area and building sites
are normally can be recovered or rebuilt on condition. After the exterior
interference factors stop, the vegetation on both roadsides will recover toward the
original types before destruction. The speed of recovering and substitution
depend on the degree of exterior factor actions and length of time, generally 2~3
years after end of the project, the vegetation can be basically recovered. The
temporary land occupation and land for earth taking will destroy the vegetation in
the said area, but it can be recovered into the original state if the efforts are made
for the activities of vegetation recovering after end of the project.
(3) Loss of Vegetative Biomass
After the land requisition, the wood land inside the redline becomes road surface,
the green fields of various arbors, woods and grass vegetation, the vegetation
coverage in original environment are reduced and vegetative biomass is lessened;
the ecological system goes from productive and ecologic types into road
ecological protection under the manual control, the function changes. Since the
belt type land surface vegetation loss due to land occupation for building activity is
less compared with the total vegetation along the line, the road greening itself will
offset partial biomass loss, and therefore, this project will not impact the richness
and ecological function of the ecological system species along the line.
(4) Other Impact over the Vegetation in Building and Operation Periods
The completed road will bring forth a large amount of vehicle flow and energy flow,
the vehicle tail gas and smoke directly impact vegetation growing. The dust and
earth-taking and discarded rubbles caused by building activities will lead to soil
erosion, the indirect impact factor to the vegetation. The environment factors due
to such direct and indirect impacts will influence vegetation normal growth. Since
the dust raised by road impacts less the surroundings, the impact to vegetation
natural growth is limited.
2. Impact Analysis on Areal wild Animals
New roads building will render a certain impact over the regional wild animals, but
after the short time escaping, under the pressure of population habitat and food
competition, most of the wild animal varieties are forced finally to adapt to road
building environment impact passively and mutualism can be realized with human.
Those of mutualism with human are the animals of rodents, birds and
amphibians, they move to the similar environment nearby in project construction
period, and will adapt to the proper environment to return to the road areal
ecologic system after the vegetation recovered in the end of project. And part of
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
130
population numbers will increase due to ecological environment stability
improved.
Since the continuous natural space is separated as less as possible in road
design, it will secure the integrity of EE (ecological environment) to a great extent
and relieve the impact over the surrounding wild animals and vegetation after the
operation of roads. Meanwhile, there is no large animals in that area, some small
animals requires the limited area for their habitat, therefore it impact less the
animals distribution and activities due to road separation.
6.6.4 Impact Analysis on Agricultural Ecological
The impact over agricultural production along the line of road building can be
classified into two sides -- one side, road building benefits the farming activity,
quickening agricultural and forestry by-products circulation, strengthening farmers
confidence for their production so as to raise the production per unit area since
the traffic condition is improved, this impact is indirect and positive; other side, is
that road building occupies farmland to cause actual production area reduction to
lead to agriculture loss and its impact is direct and non-recovered.
After the road completed, the unused land can be easily developed because of
the handy traffic, but the permanently occupied land will lose its faming functions
forever, the occupied land will lose its farming functions temporarily, which will
lead to some negative impact to farming.
Firstly, the land occupied by project will cause crop production reduction, the
impacted agriculture vegetations are rice field and dry field. Secondly, the
temporary land occupation in the project will also impact the land utilization and
economy to a certain extent, this impact will not disappear after the project
completed and the original utilization functions shall be resumed by manual efforts.
By means of the following measures, the negative impact to farmland can be
controlled within the limited scope.
① It is required that the temporary occupation land should use the wasteland
or non-farmland in the project, as to the farmland have to be used, before the use,
the farmland surface soil layer (30cm) shall be stocked in a place and return it for
crop growing after end of project to recover the original soil function;
② Use less temporary occupation land as less as possible and the original
functions can be basically recovered through clearing up and treatment after end
of project;
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
131
③ Related compensation will be given to the temporary used land in terms of
the policy concerned. Finally, the raised dust due to the constructional vehicles
running through the farmland will impact crops photosynthesis to cause less crops
production. This impact is prominent in the initial period and less in the post
period;
④ Considering road building is linear engineering, the occupied land is only
small part of land area, therefore, permanent land occupation impact less to whole
area, but the impact much to the residents at the concentrated land requisition. It
can be relieved by means of land regulation, more job-hunting or land
compensation through township government.
Moreover we recommend the project undertakers shall use the low production
field and not to used high yield one in the design to reduce the loss to agricultural
production.
6.6.5 Conclusion on Ecological Environment Impact
(1) In the area through which the project extends in belt shape, the
vegetations in the road area are destroyed, yet this destruction merely impacts
local areal plants varieties, as to a large area, the belt shape destruction will not
damage the increase and decrease of areal species, nor the perish of certain rare
plant species, at same time, some renewal and compensation can be made by
some manual planted protected plants. Therefore, the areal plants diversity will
not decrease.
(2) Seen from the areas on the completed similar roadsides recently in our
country, they are able to keep the original land utilization function and
non-impacted farming structures. The land occupation area in this project has
small proportion to the areal total farmland and it will not change the areal
agricultural structure and farming mode, nor reduce local agricultural production
neither.

7. POLLUTION PREVENTION AND
TREATMENT MEASURES IN
OPERATION PERIOD
7.1 SOCIAL ENVIRONMENT IMPACT PREVENTION AND TREATMENT
MEASURES
The impact to residents along the project’s line are mainly the residents travel and
crossing due to the widened roads, dense vehicle flow and fast vehicle speed,
and the noise impact to the civilians along the line is also undesired, the
measures taken shall be as follows:
(1) The impact to residents on both roadsides is basically the noise, after the
roads completed, the greening belts on roadsides shall be build as soon as
possible to minimize the impact to the residents. Meanwhile, ventilation/acoustic
insulation windows can be installed according to actual situation to solve the
problems of opening windows to cool and reduce noise in summer.
(2) After the project, trees and grassland shall be planted by means of good
use of the motor vehicle and non-motor vehicle isolation belts’ both sides to
supplement or reduce the occupied green land losses. On the other hand, a
qualified professional environment team shall be organized to carry out the
periodic maintenance for the green belts.
7.2 Ecological Compensation Measures and Greening Plan
(1) The trees, flowers and grass on the demolished area shall be transplanted
into another place, better transplanted inside the project community to let them
survive to compensate the trees, flowers and grass destroyed by the permanent
land occupation; newly built roads shall be designed with the parterres, grassland
and evergreen ornamental trees in isolation belts and nearby buildings as much
as possible to let the reduced greening area compensated.
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
133
(2) Greening belts, grassland and hedgerows shall be designed on both
roadsides; some sculptures and greening patterns are erected in the spaces in
intersection and between buildings, which do not only improve urban environment,
beautify roads landscapes but also improve urban image and harmony.
The project afforestation plan refers to Table 7-2-1.
7.3 Atmosphere Pollution Prevention Measures
This project atmosphere pollution source is the motor vehicle running on roads,
which are moving source, and it is difficult to control their tail gas with one or more
bridges and result can hardly be achieved. On the basis of experiences from both
home and abroad, vehicle tail gas control is a systematic engineering for a city or
region. Thus, its control relates closely to the vehicle emission control measure of
the whole Bengbu, even Anhui Province or China. Therefore, the said measures
shall be connected with those of local and national efforts.

2. Pedestrian pavement is designed with evergreen arbor of
southern magnolia to separate the pedestrians with noisy vehicles,
functioning in separation, insulation and protection.
The project’s contractor and managing organizations shall carry out the various
policies and measures over the motor vehicle tail gas emission control from the
sense and action and take some related measures for such controls, in detail, the
measures of this report to be taken as follows:
(1) The vehicles whose tail gas exceed the standard are forbidden for running
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
134
Today, the road and annual inspections are carried out on vehicles tail gas
pollutant emission in Bengbu, in order to reduce its emission, the urban traffic
management department shall forbidden the standard exceeding vehicles travel,
which will relieve the air pollution from this project to a certain extent. Currently, in
order to reduce vehicle pollution, the strict vehicle pollutant emission standard and
pollutant emission amount per vehicle are being executed, only in the whole city
strict control of vehicle tail gas pollutants be done, can such as pollution not be
more and more, which is also line with the tide of motor vehicle industrial
development both home and abroad. Both of home and abroad experiences show
that only the single vehicle emission amount is reduced, can the air quality not be
deteriorated while the fast vehicles are increasing.
(2) Strengthening Vehicles Inspection and Maintenance
Practice shows the relation matters much between motor vehicle tail gas pollutant
emission and if the engine is on the normal technical state. The frequent vehicle
exhaust exceeding the standard is mainly because of low level maintenance and
engine state deterioration etc. After the vehicle using non-lead gasoline and
installation of tail gas purifier, it is critical for the inspection and maintenance.
Therefore, vehicle maintenance and inspection shall be strengthened to let them
on satisfied condition to reduce tail gas pollutants emission. At the same time,
some measures can be also taken such as improving vehicle performance and tail
gas purifier to minimize the absolute emission of pollutants.
(3) Deceasing Dust on Road Surface
Since the raised dust is from the settled dust particles on road surface, this dust
particles reduction means minimization of the pollution source intensity. In order to
reduce dust particles on road surface, the vehicles transporting the dust
containing materials shall be covered with tarpaulin to control materials dropping.
(4) Close Cooperation with Local Government for Strict control of Vehicle Tail
gas pollutants
Since vehicle tail gas pollution is a systematic control engineering effort for a city
or region, it can not solve the pollution problem simply by the pollution control over
the vehicle tail gas pollution on one or some roads. Therefore, the traffic
management departments shall work actively with local government and
environment protection departments to control such pollution.
(5) New Sensitive Point Far Away from Lines
New sensitive point far away from lines will reduce tail gas pollution, research
shows that the distance from pollution to receptor impacts the receptor pollutant
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
135
concentration directly, the far the distance is, the less pollutant concentration the
receptor gets. Therefore, if the distance from the roads to the sensitive point along
the lines to increase to expand the free space of between vehicles and nearby
sensitive points, it will benefit the dilution of the pollutant concentration in the
process of transmission to decrease its concentration when to the receptor. Thus,
we suggest the planning department not to put new sensitive points in the area
within 50m on both roadsides and move such points away and change them into
the enclosed buildings such as commercial shops, office buildings and
warehouses etc. The 1st row buildings shall be backward as much as possible to
keep a certain distance to roads, which will relieve the undesired environment
impact from the raised dust from vehicles tail gas to a certain extent.
(6) Purification Air with Vegetation
The test shows that the broad leaf arbor on both roadsides functions in dust proof
and pollutant purification to a certain degree, the builders shall carry out the
afforesting on roadsides to purify the environment air with vegetation space.
(7) Opening Public Traffic, Developing Public Bus Service and Increase of
Green Land Area
Opening the public bus service to let the convenient urban traffic to reach every
part in the city so as to attract more civilians to take public bus and reduce private
cars, or raise the private car using cost to control its amount, in this way to reduce
pollutant emission from the source; at the same time, increase the greening areas
on both roadsides to purifying the pollutants to a certain extent.
7.4 NOISE POLLUTION PREVENTIVE MEASURES
7.4.1 Environment Protection Measures Comparison
Today, the noise pollution control project consists of: erect acoustic barriers on
both roadsides, noise-reduction (sound absorption) road surface on the ground
and do some comprehensive treatments on the impacted buildings etc. Table

7.4.2 Measure Plans Selection of Traffic Noise Pollution Prevention
Known from the noise pollution predication, after the project, the sensitive points
in daytime in 2014 are able to reach the related standard; the other sensitive
points at night except for Huangxiang fail to fulfill the standard and the standard
exceeding range is 3.14~5.08dB(A); in 2021 the other sensitive points at night
except for Huangxiang exceed the standard and the exceeding range is
1.01~2.31dB(A); at night all the sensitive points exceed the standard, and the
exceeding range is 0.94~7.83dB(A) in daytime.
With comparison of those of same noise prevention experiences from Guangzhou
and Tianjin, the noise reduction will be down to more than 20~25dB (A) if the
ventilation and sound insulation windows installed, and the fresh air in side room
is able to meet that demand of (GB/T18883-2002) “Room Air Quality Standard”,
this technology after years modification is mature, the practice shows that it is
effective and economic measure to control traffic noise.
As for the sensitive points located at urban lower buildings, it is suggested to
install ventilation and sound insulation windows on the building sides which face
the roads, the noise reduction is 10dB(A), which is able to meet the demand to
noise reduction in the project.
Thus, from the view of environment protection, this assessment suggests the
constructors to install the ventilation and sound insulation windows to the
suburban lower buildings; as for the residence points which have been listed into
Bengbu General High Speed Railway Demolishment and Resettlement Plan,
certain compensation can be given if the noise level exceeds the standard.
7.4.3 Traffic Noise Pollution Preventive Measures
-- Principle of Noise pollution prevention
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
138
As for the newly built roads, the environment sensitive points which are
predicated to exceed the standard shall be controlled with noise reduction
measures to secure its standard approaching; as for the residence area, all the
buildings shall be installed with ventilation and iisulation windows.
(1) Reasonable planning and Layout on the land on both roadsides
On both sides of newly built roads, the 1st row buildings do not fit for building up
the sensitive point units such as schools, hospitals and kindergartens, some units
which require less for the sound environment can be built such as commercial
buildings, multiple parking lots etc., which does not only make good use of land
but also relieve the noise impact to some acoustic sensitive targets.
While designing the function layout of residential buildings, the auxiliary facilities
such as bath room, kitchen and elevator room can be designed on to roadside to
reduce the noise impact.
As for the newly built constructions on both roadsides, the owners of the buildings
are recommended to take sound isolation treatment in the structure in the design
and construction i.e. the doors and windows should adopt the ones with sufficient
ventilation and sound insulation to avoid the noise impact from the project.
(2) Protective Measures on the Environment Sensitive Targets along the Lines
According to the noise predication and impact analysis and environmental
characters of the environment sensitive targets along the lines, the proposed
project acoustic environment sensitive points’ environment protection measure to
be taken are to install ventilation and sound insulation windows in the sensitive
points -- the suburban low rise buildings such as rural residential areas; as for the
residential points listed as the city high speed railway areal overall demolishment
and resettlement plan, certain compensation will be given in case the noise level
exceeds the standard.
(3) Vehicle Noise Control, Road Traffic Management System and Road
Surface Maintenance
Gradually perfect and improve vehicle noise emission standard; carry out
periodical motor vehicle noise test, enforce the standard exceeding vehicles to be
maintained and not to travel on roads until they reach the standard. Eliminate
severe noisy vehicles; formulate single motor vehicle noise control plan and target
to reduce single vehicle noise level, which is the most direct and effective
measure for reducing road traffic noise; install high efficient silencer to lower
engine and exhaust noises; strictly limit driving speed in sensitive road section,
especially the speeding at night; strengthen the whistling control on motor
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
139
vehicles and forbidden the whistling on road sections with more environment
protection targets; periodically maintain and service sound isolation facilities;
maintain well road surface and recover the damaged ones in time.
(4) Improved Condition after Treatment Measures Taken
With the economic development and auto manufacturing technical level enhanced,
the stricter criterion on vehicle noise level can be stipulated so as to decrease the
road traffic noise value gradually.
As for the acoustic sensitive targets along the lines, after the ventilation and
sound insulation windows installed, the room environment noise level can also
reach the related standard requirement.

8. PUBLIC CONSULTATION
8.1 THE PURPOSE AND MEANING OF PUBLIC CONSULTATION
Under road construction, it is the one of the critical issues in the environment
assessment as it is involved in land occupation, civilian residences demolishment
and resettlement, which concerns significantly farmers’ interests. The public
consultation is most important to the decision making since it reflects public
commends to the project to let the decision making departments find problems,
modify and perfect design plans and solve them, and on the other hand, to let the
project plan more reasonable and perfect to reach the harmonious coordination
between economic benefit, environment benefit and social benefit. Meanwhile,
letting public know the project and forwarding the claims and suggestion over the
project can not only gain the understanding and support but also let the civilians
be aware of the environment friendly sense, supervise the EE (environment
assessment) work and protect ecological environment to guarantee the strategic
implementation of sustainable development.

9. ENVIRONMENT IMPACT ANALYSIS
ON DEMOLISHMENT AND
RESETTLEMENT
9.1 PROJECT DEMOLISHMENT AND RESETTLEMENT PROFILE
9.1.1 Requisition of Collective Land
This project needs to commandeer 23.9843 hectares collective land permanently,
in which there are 13.3302 hectares rice field, 6.8855 hectares dry land,
2.71hectares water area and other 1.0226 hectares rural building land.
9.1.2 Residential Houses Demolishment
The houses demolishment in this project mainly is because of the building of Lilou
Road and Fengandong Road, totaling 24601m2 demolished rural residential
houses 273、1094 peoples impacted. The demolished houses are mainly 2 floor
brick/concrete structure houses; since some of the buildings along the line are 2
floor building of which the first floor is used as shops and 2nd floor for living,
therefore, the shops will be included in residential houses demolishment and
resettlement in this report, thus this project does not contain those of commercial
shops and enterprises and institutions.
9.1.3 Disadvantaged Groups
There are 3 people of 2 families as disadvantaged groups in this project. The
impact comes from the demolishment. After investigation, the said group have the
difficulties in resettlement, thus special financial support will be given.

9.4 COMPENSATION PRINCIPLES ON DEMOLISHMENT AND
RESETTLEMENT (DR)
9.4.1 Principle of Minimization of Residents’ Demolishment and
Resettlement
On the basis of project characters, modify the direction of design to reduce the
impacted scope in this project as much as possible to minimize its impact.
9.4.2 Principle of Equivalent Compensation
In order to secure the residents’ life level not to deteriorative due to this event, the
equivalent compensation principle shall be carried out, which includes two
aspects: 1st – the property shall be compensated in line with resettlement cost; 2nd
– other losses shall be recovered on equivalence, i.e. how much the influenced
residents lose, how much the compensation they will be given to.
1. In case farmland is commandeered, all the losses will be compensated
reasonably, the compensation value will be delivered to the collective, which
represents to use it for developing collective economy and shall not be used for
other purposes. The residents under DR engaged in farming will be employed by
the local government, project offices and village commission jointly according to
the principle of “Settlement locally and employment in multiple ways” to secure
such residents’ lives not to be impacted.
2. The residents’ families under DR will be furnished the houses with traffic,
various supporting facilities and surroundings which are equivalent to the original
ones or the financial compensation with the value equal to the original houses.
3. Public facilities shall be recovered completely, their functions at least are
not lower than the original level to guarantee the normal lives of residents who live
outside of the project area and do not move.
4. Those who are impacted by DR of the project temporarily or those who
don’t need to move but their partial properties are impacted by DR of the project
will also be compensated with the equivalent value.
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
153
9.4.2 Principle of Focusing on Importance
1. The project shall take care of the disadvantaged groups (the old persons
who have no children to live together with, widows, single parent families,
disabled persons, chronic disease patients and poor families), a certain
preferential policy shall be given to them when the removal is started i.e. the
reasonable carefulness such as housing and employment. After resettlement,
they will be visited periodically to furnishing some supports for some specially
difficulties until they are transferred to civilian administrative department.
2. The project will plan the developing removal, encourage the local
government to hold the job trainings for the residents of DR and try to create more
jobs for them to enable them to adapt to new resettled points in short time and to
be independent economically and transfer the DR responsibility from the
settlement organs to the residents of DR.
3. The project will try to maximize the benefits of DR, improve the DR organs
working ability, normalize the DR behaviors, set up perfect interior control
mechanism to prevent the fund waste, retaining, fraud and corruption and make
satisfied use of DR fund to achieve the best settlement result.
9.5 Production and Life Recovering Plan of DR Residents
9.5.1 Plan of Permanent Land Requisition
This project needs to commandeer 23.9483 hectares collective land permanently,
in which there are 13.3302 hectares rice field, 6.8855 hectares dry land,
2.71hectares water area and other 1.0226 hectares rural building land. Since this
land requisition impact is aroused by road building which assumes linear
distribution, most of the land-requisition persons lose their partial land, therefore,
land requisition impacts less to farmers farming and incomes.
In line with the sampling survey made on DR impacted residents, the impacted
persons all demand monetary compensation and meanwhile, land change will be
done inside the group. After this, farmers are able to continue their farming and
keep stable income. This project involves 4 villages permanent land occupation
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
154
and there are 4 kinds of measures to help the DR residents in their life recovering
as follows:
a) Direct monetary compensation and farmland change. Strictly carry out the
policies of state and local governments to determine land requisition
compensation standard and lost farmland amount, and directly pay the
compensation fund to the impacted residents’ families. The resettlement subsidies
will be directly paid to the impact people and land compensation fund will be
retained in the village collective; the farmland change shall be done inside group
to let the impact people go on their farming.
b) Social Security: in compliance with the regulations of “The Notice on Some
Issues on Further Perfection of Urban Land Requisition and Demolishment and
Resettlement” (BZB [2010] 62), in the limit of Bengbu Planning Area, after land
requisition is approved in laws, the people who lose land completely or whose
average and actual farmland area is less than 0.3mu per farm population or who
are not 16 years old and don’t have city and township basic endowment insurance
when the requisition is done are taken into the range of land requisition farmers
endowment insurance. This project compensation fee will sufficiently make up the
farmers land earnings in the term of land contraction and meet the demand of
paying endowment insurance for them who lose their land as well.
c) Improve agricultural production conditions: village collective will raise the
fund and use partial compensation from the collective land requisition into farming
activities such as soil and soil quality improvements, reform the low-yield farmland
and grow cash crops.
d) Regulate agricultural structure: Every village shall make good use of its
own geographic position and market condition, regulate structures of crops
growing and breeding to heighten their farming incomes, e.g. integrating their own
farming history and reality, develop shed vegetables and scale breeding etc.
Meanwhile, the DR settlement organs shall give some assists as follows:
(a) In the process of building, the employment shall be first assigned to the
residents who are of DR to let them earn cash income;
(b) The project of labor export shall be given to the persons preferentially who
are impacted by the project within the limit of villages;
(c) In overall DR residents’ production recovering, the impacted persons can
be organized for technical trainings, i.e. the trainings of some cash crops growing
and breeding etc. invite some technical persons from agricultural or labor security
departments to do some trainings in terms of agricultural and farming technology
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
155
to let the impacted people receive farming technology and non-farming production
trainings at least more than one time. With the mentioned measures, enhance the
crops yield and quality, increase their economic incomes and recover their means
of livelihoods.
9.5.2 Demolishment and Resettlement Plan of Residential Houses
The houses demolishment in this project totals 24601m2 demolished rural
residential houses and 273、1094 peoples impacted.
This residence DR houses settlement involved in the project shall be solved in the
way of “overall demolishing and overall resettlement”, in which DR settlement job
will be done by Longzihu District government, the land requisition involved in the
project will be ended at the end of May 2012. The resettlement residential quarter
is called Taoyuanxinchun Residential Quarter in high speed railway area (see Fig.
9-5-1), which is located in the south of planned Xueyuan Road, the land block
GT-F01of east of Gaotiedong Road of 84269m2 planned area, 211238m2 total
construction area, in which building area is 198818m2, 9311m2 supporting
commercial building area, 3108m2 auxiliary public facilities, 1220m2 kindergarten
and 40.2% greening rate. This residential quarter will be completed at the end of
2012, at that time, the said residents can all move into this quarter, at the same
time, the surroundings are residential purpose land in terms of high speed railway
plan, which is adjacent to the two main roads – Gaotiedong Road and Xueyuan
Road with full living facilities and convenient travel conditions.
The overall settlement population can select the houses according to their
removed area. The part with the resettlement area equal to the original area can
be calculated and settled in terms of overall settlement standard, structures,
location and year condition. The resettled area exceeding within 10m2 of the
original removed area shall be calculated and settled at cost price; the part of
resettled area exceeding more than 10m2 of the original removed area shall be
calculated and settled at market price.
9.5.3 Resettlement Plan for Disadvantageous Group
This project involves tree disabled persons, who basically lose their working ability and are difficult for their life. The settlement for them is to list them into Bengbu social security system and let them get the basic living fee monthly and live in stable life.
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
156
Women will take part in fully in the settlement activities by means of public information notice and joining in the village collective meetings; they have the equal right as men in the compensation, project employment and trainings. Moreover, the measures will help them gain the income as follows: In the project, a certain number of women (at least 20% without working skills) will get the non-technical employment and women will obtain the same income as men if the jog is same; In the aspect of technical training, including the hour employees and hairdressers, the jobs will be given to impacted women preferentially to secure their economic status not be impacted.
In the process of project, the jobs of cleaning workers and gardeners will first deliver to project impacted women to guarantee their income.
9.5.4 The Recovering of Ground Appendages and Infrastructure
The impacted ground appendages will be re-evaluated in line with replacement price and the reconstruction will be done by the property owner after the reasonable compensation. The measures of impacted infrastructure restoration shall be first the planing and arrangement, in the actual operation, it shall be carried out in terms of the actual situation, safety, high efficiency, in time and accuracy to minimize the negative influence to the residents nearby.
9.6 Living Quality Change Analysis of the DR Residents
In the period of DR, the residents’ (whose houses will be demolished) lives and travel will be interfered, but the impacts are short and temporary. And the impacts brought forth by this even is limited if the settlement measures are well done in terms of principle and policies of DR settlement and compensation from Bengbu municipal and World Bank. The houses to be demolished are mostly old, long time, antique and incomplete in facilities, poor surroundings and unsatisfied people travel condition. The residence quarter planned in the resettlement residences in this project is listed in Bengbu High Speed Railway Area Plan. According to the plan, in the residence zone, there are green areas, satisfied environment, complete utilities such as water/power supplies, telecommunications and traffic etc. and the buildings nearby are designed with shops for catering, stores and repairing etc to make the local residents convenient in life.

11.3 ENVIRONMENT GAINS AND LOSSES
As for the infrastructure engineering, it will bring about some negative impacts
over the nearby acoustic environment, atmosphere environment and ecological
environment in project building and operation periods, but the higher EP
investment is able to make up the environment negative effects caused in the
project.
The benefit for the investment for EP measure is significant, long term and
potential. Those measures will protect the environment along the road lines to a
certain extent directly or indirectly to let road building impact to environment down
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
171
to lowest level. The environment benefits are mainly represented in two aspects
as follows:
(1) After the project operation, the vehicle flow will increase and the produced
noise and tail gas pollutant will impact the environment along the lines and
environment sensitive points nearby. Thus, some measures shall be taken
such as growing trees and grassland to reduce the traffic pollution to both
sides’ ecological environment and people’s life. At the same time of the
project building, the said afforestation in proper time is also able to prevent
the soil erosion on road slope and toe and have the vegetation protected.
(2) Environment Quality Benefits
① Optimize the urban landscape along road lines, beautify environment
and enhance people’s life quality,
② Due to the project building, the atmosphere, land surface water and
acoustic environment will be brought forth a certain undesired impacts and
permanent land occupation will emit some ecological losses to cause
environment negative effects, but the higher EP investment will make up
some losses.
③ The existing road drainage system is not perfect and the draining
mainly utilizes the roadside open ditches, after the project ends, the
perfect draining system will improve the current roads draining status and
the possibility of soil erosion reduction.
④ Since the road surface pavement is upgraded and road condition is
improved to a great extent, which will raise vehicles speed, reduce oil
consumption, lessen raised dust, noise and waste gas emission, relieve
vehicles’ wearing so as to save energy and substance resources indirectly.
⑤ Some current road conditions are poor and heavy dust will be raised in
dry season; when vehicles are moving, the raised dust would impact the
other road users such as residents nearby, non-motor vehicles or
pedestrians and the upgraded roads will optimize this state.
⑥ The perfection of the traffic facilities and traffic signs on upgraded
roads will provide the road users a perfect road conditions to let them
convenient and easy in travelling and decrease traffic accidents as well.
In one word, the project to be built will make functions in Longzihu District
more reasonable and beneficial to urban environment quality improvement,
therefore, it is of satisfied environment benefit.

12.1.3 Environment Quality Status
(1) Environment Air Quality
The current state test result shows that the concentration monitoring values of
SO2,NO2 per hour and per day and that of TSP of daily average concentration at
every test point are all able to meet the requirements of II category standard of
“Environment air quality standard” (gb3059-1996), but the monitoring values of
daily average concentration of PM10 in Lilou Village and Hange Village are beyond
of the standard in terms of the current survey, the said “beyond of the standard” in
the two villages are mainly because of the sand roads mostly in the said area, and
there are building sites there, the raised dust caused by the vehicles’ transport
and building activities in the sites impacts the village’s environment air seriously.
(2) Acoustic Environment Impact
The current environmental acoustic quality along the newly built roadsides
is satisfied to meet the requirements of “Acoustic Environment Quality
Standard” and residents are living in quiet condition; the existing noise
from Donghai Avenue impacts Shanwang Village less.
(3) Land Surface Water Environment
In every monitoring crosssection in Longhu Lake, the monitoring values of pH, DO,
COD, ammonia nitrogen and permanganate are not found beyond standard,
which means the water quality in Longzi Lake meets the requirements of III
category of “Land Surface Water Environment Quality Standard” (GB3096-2002);
in every routine test cross-section in Huaihe River, ammonia nitrogen test values
are beyond the standard at two test sections under Huaiganxin Bridge and in
Mohekou, the test values of others’ every monitoring factor are up to the
requirements of III category of “Land Surface Water Environment Quality
Standard” (GB3096-2002).
12.1.4 Building Environment Impact
In this construction period, the building activities of various pipeline Subsurface
Networks demolishing and removal, urban green field occupation by project,
farmland occupation by project, dust raised by building and work noise etc would
bring forth different level of impacts to urban social environment, ecologic
environment, environmental air quality and noise. Therefore, this assessment has
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
174
formulated considerably comprehensive pollution prevention and treatment
measures and the building impact will be down to the minimum level if the strict
management, diversified preventive and relieving measures are taken accordingly.
Building impacts are temporary and most of the environment factors will be
resumed to the original level after the end of construction period.
12.1.5 Environment Impact in Project Running Period
(1) Analysis on Social Environment Impact
After the project fulfilled, the road-network traffic capacity, urban beautification
and urban multiple functions will be enhanced overall to benefit urban residents

lines will be heightened rapidly to realize the land market value; it drives the
industries, commerce, services and IT in different sector in the city to accelerate
economic construction; it will promote investment environment and tourism
significantly. Therefore, it can be thought this project is a civilian-beneficial one
integrating social benefit, economic benefit and environment benefit all together.
(2) Atmosphere Impact
In line with analysis, in 2014 and 2021, the pollutants concentration 20m~200m
downwind in Lilou Road and Fengandong Road will be decreasing gradually, the
impact in static wind within 40m to redline territory is more than that of normal
yearly average wind speed; the normal yearly average wind speed impact 40m
out of the redline territory is more than that in static wind speed. Through the
predication, the tail gas -- NOx and CO concentration down wind exhausted by
vehicles on every road section are able to reach the standard, and the impact in
2020 is less than that in 2030, and EP target impact concentration within 5~200m
on every road section is able to meet standard completely.
(3) Acoustic Environment Impact
After the project fulfilled, the daytime sensitive points in 2014 are able to reach the
related standard; at night, except for Huangxiang village, all the other sensitive
points are all beyond the standard with exceeding value range 3.14~5.08dB (A);
in 2021, in daytime except for Huangxiang village, all the other sensitive points
are all beyond the standard with exceeding value range 1.01~2.31dB (A); at night
all the sensitive points are beyond the standard with the exceeding value range
0.94~ 7.83dB (A)

(1) Heavy noise and high vibration equipment are forbidden to work at noon and night period, the builders shall employ low noisy machineries or those with sound insulation and silencer. (2) Arrange the working time reasonably, under normal situation, the noise in daytime impacts less to residents’ normal life, more to them at night. Therefore, reasonable building management shall be done to avoid the impact to the residents’ rest and sleep in that period of time. (3) Arrange working sites reasonably, heavy noisy working sites shall be far away from noise sensitive points, as for some serious impact sites, temporary sound insulation and coverings shall be done, and some temporary labor camps can be set up to substitute the noise insulation wall; earthwork shall be done by more machines’ working at same time to shorten the impacted time; the fixed noise sources in working sites can be also concentrated to reduce vibration interference range. Before the work is done nearby the residential areas, temporary sound barriers measure shall be taken to reduce the noise. (4) The vehicles which are traveling to or from the working site shall be away from the residences’ side. (5) In accordance with the regulations of “Environment Noise Pollution and Treatment Rules”, the builder organizations shall apologize or compensate the impacted organizations or individuals in case the noise-reduction measures taken still fail to reach the formulated value in the standard.
