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 order to meet World Bank relevant safeguards policy requirements.

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.
Table 3-4-1 The Compactness of Soil Road Foundation
|Filling/digging |Depth（cm） |Compactness |
|type | | |
| | |High speed road/ |Sub-main road |Sub-road |
| | |main road | | |
|Filling |0～80 |95/98 |93/95 |90/92 |
| |80 or less |93/95 |90/92 |87/89 |
|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;
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 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.
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.

② The lane to guide the said disables shall be of strip type one and the dot shape warning lane for blind person shall be designed in start point, end point and turning point.
③ The thickness below the contact sensing part of blind walk way surface shall be same with that of bricks of pedestrian pavement;
④ The blind walk way shall be continuous and not be the obstacles such as wire poles, bracing wires and tress etc.
⑤The blind walk way shall be away of the well-shutter facilities;
⑥ The blind walk way shall be yellow color;
(2) Curb Ramp Design
① The crossings of all kind of pedestrian pavements shall be curb ramp;
② Curb ramps shall be designed within and in line with the pedestrian walkway.
③ Curb ramps can be classified into single face and tri-face curb ramps;
④ Curb ramps’ slope shall be flat and unsmooth;

In the main roads which are of fast road + auxiliary road, the stereoscopic road crossing facilities shall be designed reasonably in line with pedestrian flow to secure their street crossing safety; pedestrian plane street crossing facility shall be also laid in opening intersections to control their crossing with signal lamps; pedestrians crossing self help system shall be designed at non-intersection and pedestrian overpass. The slow street crossing facility will be designed in terms of public bus stops and intersections. Pedestrians crossing protection zone shall be designed in all pedestrian street crossing positions. Traffic lamp control shall be adopted over the pedestrian pavements at intersections, in which the linking control mode shall be used at approaching distance.
Moreover, in terms of the pedestrian crossing walkway, necessary marking sign lines shall be designed; the signs are mainly pedestrian street crossing signs, which include pedestrian crossing deceleration marking lines, stop for prior driving lines etc. As for the intersections with signal lamp control, pedestrian special signal shall be added, such as intellectual warning plate, green light indication map, sound raising for blind persons crossing, pedestrians’ crossing self help system, runway light designed in pedestrian crossing pavement to help them crossing streets, time counting down lamp and electronic cameras etc.

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 machineries refers Table 3-9-1 as follows:
Table 3-9-1 The Actual Test Value of Common Road Building Machineries

|11 |Concrete mixer |JIC350 |5 |91 |stationary steady source |
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:
Table 3-9-2 TSP Concentration in Building Site
|Construction |Cause of Dust |wind（m/s） |distance（m） |concentration（mg/m3） |
|Earthwork |Load/unload, transport, site |2.4 |50 |11.7 |
| |construction | | | |
| | | |100 |19.7 |
| | | |150 |5.0 |
|Dirt/dust |Load/unload, mixing, transport, |1.2 |50 |9.0 |
| | | |100 |1.7 |
| | | |150 |0.8 |
|Stone/gravel |transport |2.4 |50 |11.7 |
| | | |100 |8.8 |
| | | |150 |5.0 |
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.
Table 3-9-3 Solid Discarded Materials
|No. |Title |Unit |Amount |Place to deliver |
|1 |Surflaes from house |X10000m3 |2.6 |For other roads’ greening belt /landscaping in the city |
| |demolishing | | | |
|2 |Building rubble |X10000m3 |1.2 |Some recycled and the others transported to urban refuse |
| | | | |landfill by city environment hygienic dept. |
|3 |Living rubbish in building |t/a |29.2 |transported to urban refuse landfill in fixed time by city|
| |site | | |environment hygienic dept. |
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 land |Rice land |133308 |/ |
| |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 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
of Under the Speed of Diversified Typical Vehicles
|Vehicle type |Pollution |Emission index under average vehicle speed (unit：g/km· vehicle) |
| |Factor | |
| | |50 |60 |70 |80 |
| | |
|Small vehicle (3.5t below) |Ls=59.3+0.23V |
|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) |
|Small vehicle (3.5t below) |66.2 |68.5 |70.8 |
|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.
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 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:
Table 4-3-1 Comparison of Road Surface Materials
|Advantage/disadvantage |Modified asphalt Road |Cement Road Surface |Road Surface |
|Comparison |Surface | | |
|Impact to environment |More maintenance frequency, |Less maintenance in normal operation|Longer maintenance interval relating |

In one word; they have different advantages and disadvantages, the noise reduction road surface will be recommended on both road sides where there are more residential areas considering the investment and maintenance costs over different road sectional requirements, the other ones employ modified asphalt road surface.
ENVIRONMENT IMPACT ASSESSMENT AND POLLUTION PREVENTION MEASURES IN CONSTRUCTION PERIOD
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
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 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 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.
(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 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 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.

1. 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.
[pic]
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.
Table 5-4-2 Falling Velocity of Different Dust Granule Sizes
|Dust granule size (μm) |10 |20 |30 |40 |50 |60 |70 |
|Falling velocity (m/s) |0.003 |0.012 |0.027 |0.048 |0.075 |0108 |0.147 |
|Dust granule size (μm) |80 |90 |100 |150 |200 |250 |350 |
|Falling velocity (m/s) |0.158 |0.170 |0.182 |0.239 |0.804 |1.005 |1.829 |
|Dust granule size (μm) |450 |550 |650 |750 |850 |950 |1050 |
|Falling velocity (m/s) |2.211 |2.614 |3.016 |3.418 |3.820 |4.222 |4.624 |
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:
(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
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
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 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 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.
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.
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
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.

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
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 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 7-4-1 list the noise reduction result, costs and advantages/disadvantages of various environmental friendly engineering measures to relieve the noise impact along the project lines.

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
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 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.

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.
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.
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 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 to let the impacted people receive farming technology and non-farming production trainings at least more than one time.

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 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.

| | |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. | |

| |Atmosphere |(1) The building site shall be hardened and concrete ground will be made if the condition is allowed; | |
| |Environment |(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. | |
| |Solid Wastes |(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 | |
