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

pollution line source. The line source center line is that of route, and source
intensity of gas state pollutant emission source is calculated with the equation as
follows:

In the equation:
jQ —— j category gas state pollutant emission source intensity, mg/(s·m);
iA —— i type vehicle forecast yearly transport capacity per hour, vehicle/h;
ijE —— under the condition of motor vehicle special road, i type vehicle j sort
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)
Small vehicle (3.5t below) Ls=59.3+0.23V
AIES Environmental Impact Assessment
Project No. 052-EIAS-2012
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)
Li(30Km/h) Li(40Km/h) Li(50Km/h)

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.

type
Predicated noise value Standard value Up to standard
Distance
10m 20m 40m 60m 80m 100m 150m Daytime Night Daytime Night
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

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.

Watering 2.01 1.40 0.67 0.60
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.

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

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.

9.1.4 Ground Appendages and Infrastructure
The appendage impacting this project is one telecommunication pole.
9.2 Policy and Regulation of Demolishment and Resettlement
The policy of demolishment and resettlement shall accord with the rules of World
Bank and the related laws and rules of China, which include as follows:
(1) “Law of Land Management of People’s Republic of China” (starting the
enforcement after the revision approved on Aug. 28, 2004);
(2) “Management Ordinances of Urban Houses Demolishment and Resettlement”
(enforced on Nov. 1, 2001);
(3) “Provisional Regulations on Cultivated Land Occupation of PRC” (Jan. 1,
2008);
(4) “The Method of Carrying out “Law of Land Management of People’s Republic
of China” in Anhui Province;
(5) “Anhui Provincial Management Methods of Urban Houses Demolishment and
Resettlement” (WZF {2—3} 153);
(6) “The Detail Rules and Regulations on Levying and Using of Cultivated Land
Reclamation Fees in Anhui Province” (CZ [2001] 1061);
(7) “The Notice on Some Issues on Further Perfection of Urban Land Requisition
and Demolishment and Resettlement” (BZB [2010] 62);
9.3 TARGET OF DEMOLISHMENT AND RESETTLEMENT
Secure the residents under the demolishment and resettlement are able to gain
all their compensations, reasonable settlement and good recovering for their the
benefits they can enjoy in this project, render a certain subsidies for their
temporary difficulties, let their income level and living standard and the
enterprises production and profit are able to raised or at least recovered onto the
higher levels before removal or project construction.
AIES Environmental Impact Assessment

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.

(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.
(1) The building site shall be hardened and concrete ground will be made if the condition is allowed; (2) In the process of digging, drilling and demolishing, watering shall be done to keep the humidity, as for the loose and dry land surface in working sites, they shall be watered frequently to control and the dust; when doing the refilling, it shall be watered if the soil surface is dry to control dust raising; it is forbidden to work in heavy windy days and determine the work sites reasonably; (3) Strengthen the management of pile yard of refilling earthwork, the earthwork surface shall be compacted, watered and covered in fixed time; the earth, building materials and discarded rubbles not need shall be removed in time, since they do not fit for stacking for a long time; (4) In construction period, the overall closed building method shall be done to control dust pollution. The earth transport and building materials transport trucks shall be covered tarpaulins, covers or other measures to prevent soil from dropping and vehicles shall not overloaded to secure there is no materials spreading; the vehicle transport routes shall be also planned; they shall not travel in sensitive points such as in downtown commercial area, traffic dense sectors and residents quarters; as for the road sections which require highly in environment protection, the transport shall be done at night according to the real condition to reduce dust impact to environment. Those soil spread on road surface by the vehicles shall be cleaned up to minimize the raising dust in the process; (5) The demolishing and road building sites shall be fenced with color metal sheets.
Water
environment
(1) The building sewage contains a large amount of earth, sand and oils, the direct drainage into canal without treatment will cause water pollution and into farmland will cause soil pollution, therefore, building waste water shall not be discharge into canal or urban Subsurface Networks. The building waste water after settlement can be discharged into urban sewage Subsurface Networks or into anti-seepage pool for concentrative storing for natural evaporation; living waste water after settlement or after digestion tank treatment can be drained into urban sewage pipeline Subsurface Networks or into anti-seepage pool for concentrative storing for natural evaporation; the sewage water produced in construction period shall not be charted into the nearby water bodies directly; (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 civilization building; (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 they are the 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.
(1) The builders shall go through the formalities of residual slurry and brick rubbish and unloading them in appointed place when the said formalities are managed. (2) The materials transport of the vehicles shall be away from the traffic peak 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 fabric; before work, the vehicles outside 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.

12.1.9 Environment Management and Supervision
In order to secure this project’s effective control and relief over environment
impact, the environmental management and supervision in building and operation
periods shall be carried out scientifically and normatively, construction period
supervision plan shall be executed strictly and construction period ES report shall
be submitted to implement diversified environment treatment measures and do
well personal EP training.
12.1.10 Comprehensive Conclusion
After the implementation of this project, it will improve the water quality of Longzi
Lake and Baojiagou to finally better the water quality in Huaihe River; meanwhile,
it will relieve the current traffic tension, reduce traffic load, remove traffic jam and
change the status of traffic disorder and crowding; it will furnish a satisfied,
advanced and modern urban traffic environment for urban development,
economic construction and people’s life. Meanwhile, the urban road network
building will improve the regional urban space expansion and land development,
optimize areal residents travel conditions and living level significantly. After the
effective measures taken for contamination control in building and operation
periods, the environment impact is accepted, and therefore, this project building is
reasonable and feasible from the view of environment protection.
