Foreword

I. Project Background

In recent years, with the gradual implementation of the strategic concept of the “New Silk Road Economic Belt” promoted by the state government and the implementation of the traffic breakthroughs in the Gansu section of the Silk Road Economic Belt, and also with the unique geographic advantages of Wuwei City as well as the implementation of policies of multi-levels, the economic and social development of the counties under the jurisdiction of Wuwei City stands at a new and higher starting point. With the rapid improvement of the external highway traffic system in Gulang County, the economic development of Gulang County has entered a fast lane and also proposed new requirements for the urban road network planning of Gulang County. In order to connect the urban area with the industrial park in an organic way and to form a peripheral loop and a framework network in the inner ring so as to ensure the necessary production and living traffic in the region, Gulang County has fully seized this historical opportunity for its development and has proposed the construction of the Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project.

Wuwei is located in the inland area with a lack of mineral resources as well as slow development. Not only is the gap between the economic development of Wuwei and that of the eastern part of China has been widened, but Wuwei’s economic development has also fallen behind the overall development of the western China and Gansu Province. In a regional development pattern where Wuwei would fall behind if it does not advance, it is imperative to find suitable ways for the development of Wuwei in the new century. With the support of the central government and the provincial government, Wuwei City has obtained the opportunity for the loan from the World Bank. The obtained loan from the World Bank will be mainly used to support Liangzhou District and Gulang County to speed up the construction of the internal traffic environment, improve the construction of the planned road network, improve the service functions of the entire road network, divert the border traffic and improve the living and ecological environment of residents along the route.

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project be carried out with the gravel soil, with the compactness being ≥ 95%.

④ The treatment of culvert subgrade

For the scope of 2H(height from the ground to the culvert platform) +3 m on both sides of the culvert platform of the open culvert and the excavation scope of the ground, the gravel fixed with cement of 3.5% shall be used for filling, with the compactness being ≥ 96%.

⑥ Treatment of old and new subgrade and diagonal streets

To ensure the stability of the subgrade as a whole and to prevent or reduce the uneven subsidence of the subgrade, first the slope of the old subgrade shall be cut by 50cm and the earthwork shall be abandoned as the abandonment. The earthwork from the digging of stairs should not be treated as backfilling earthwork, and the width of steps shall not be less than 1.5m and the slope shall be set to be inclined inward with the rate being greater than 4%. The specific bridging treatment is listed as follows:

a. The compactness of the base shall be increased by one percentage point to 91%;

b.The material used for the widened part is a type of water-permeable material, namely the gravel soil;

c. Steps shall be dug at the filling and digging intersection, and the bi-directional geotechnical grid shall be paved. The geotechnical grid is the bi-directional geotechnical grid, with the designed ultimate tensile strength being ≥ 50KN/m, and when the elongation rate is 2% the tensile strength is ≥ 20KN/m. The geotechnical grid shall be fixed to the steps with the U-shaped steel nails, with the lap width being ≥ 30-60mm.

⑦ The treatment of special culvert subgrade

The K0+220-K0+800 section of the old road subgrade of the Gulang County-Shuangta Industrial Park Road Project is the miscellaneous fill, and the average height of fill is 2m. When the subgrade strength can not meet the requirements, the treatment is the excavation of the miscellaneous fill and the replacement with the gravel soil. The widened part of the K1+400-K2+830 section is the farmland section, with the base of high water content. The treatment is the excavation of the gravel soil from the 38

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project original foundation.

⑧ The design of subgrade protection engineering

The project adopts the rhombic frame slope protection for the road fill section with the height of fill being >2m.

(2) Subgrade and road drainage

The subgrade drainage is combined with the horizontal and vertical alignment of the route, topography, geology and rainfall characteristics, taking full advantage of the natural topographic conditions. Different drainage facilities are set up to collect and discharge the water.

Combined with the actual situation of the project, the Gulang County-Shuangta Industrial Park Road Project shall be provided with the C20 cast-in-place concrete rectangular subgrade ditches with cover plates, with the size being 60cm×60cm. The foot of the fill slope shall be provided with a row of C20 cast-in-place concrete drainage ditches, with the size being 60cm×60cm. The side strip shall be provided with an opening of 50cm width every 30m and shall be reinforced with the C25 cast-in-place concrete to drain the pavement water in the motor vehicle lane to the non-motorized lane. After the collection of water by the water blocking zone, a rapids trough (road fill sections) or subgrade ditch (excavation sections) shall be set up every 30m to drain the pavement water from the subgrade.

2.2.5 Pavement Engineering

2.2.5.1 Pavement structure

The proportion of small and medium-sized buses that make up the traffic in this project is large, and the local climate type belongs to the oasis-desert area of the northern arid region (Ⅵ). Therefore, the road surface should have good resistance to high temperature and low temperature. In order to ensure the usage effect of the pavement, it is determined that 4cm fine-grained asphalt concrete (AC-13) is adopted for the upper layer and the 6cm medium grained asphalt concrete (AC-20) is adopted for the lower layer, which is moderately cost-effective.

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project

(1) Asphalt

The AC-13 fine-grained asphalt concrete has mature construction technology, with high surface friction coefficient, good skid resistance and low price. The project is recommended to be used on the upper floor.

(2) Base layer and sub-base layer

The base layer is mainly subjected to the vertical force of the vehicle load which comes from the surface layer and is diffused into the underlying bedding layer and soil foundation. The base layer should have certain strength and rigidity, and have good stress-diffusion ability. Although the impact of the atmospheric factors on the base layer is small, it is still possible for the base layer to withstand the groundwater infiltration and rainwater infiltration. Therefore the structure of base layer should have sufficient strength, fatigue cracking resistance and erosion resistance. In order to ensure the quality of the project, the project uses the cement-stabilized macadam. The lime-fly ash macadam can make full use of the industrial waste and protect the environment. It has a low cost and low early-stage strength, and the late-stage strength shall be greatly improved, but the water stability is not as good as the cement-stabilized gravel. The application of the cement-stabilized gravel is very common in the local area. It has the advantages of high strength, good water resistance and good combination with the asphalt seal. Though the surface is easy to generate shrinkage cracks, the cracks can be controlled by properly reducing the base layer modulus and controlling the cement content. The construction technology and quality control system is relatively perfect, and this project is recommends the use of the base layer of the cement-stabilized gravel.

The sub-base layer recommends the use of low-cost sub-base layer of the cement-stabilized gravel.

2.3.4 Project Schemes

2.3.4.1 Subgrade Engineering

(1) Overview of the area along the road

The new highway is located in the southern margin of the Tengger Desert. Therefore, the wind erosion and accretion effect of the strong southward (40°-50°) predominant wind direction on the alluvial fan surface has changed the original alluvial plain landscape with single form and flat terrain, which has resulted in the accumulation of some sand dunes and grassland shrub sand heap landform in the alluvial plain. The proposed project area passes through the sandy and windy sections on the road. The surface is covered with either a thick or thin layer of aeolian sand layer of dozens of centimeters thick to 1-3m thick. The sand coming from the northwest accumulates in the favorable location of the vegetation and terrain, resulting in the uneven distribution of the grassland shrub sand heaps and sand dunes of different sizes and height in the alluvial plain. The height of the sand heaps and sand dunes is generally around 0.5-2.5m, and these sand heaps and dunes are mostly of low height. Only the sand dunes in some parts of the region are relatively tall and therefore forms a variety of desert landscapes including the crescent-shaped sand dunes, crescent-shaped sand dune chain and longitudinal sand dunes of varying heights (generally around 3.0-4.0 m). The extension direction of the crescent-shaped sand dune chain is NE30 ° - 50 °.

There is grass growing on the surface of low-height sand dunes (all are semi-fixed dunes) in varying degrees, and the unprotected sand dune chain with no vegetation growing on the surface growth has a certain moving speed (according to the relevant information, the moving speed of a sand dune can be up to around 0.8m/a). The sections of the route are the atypical desert landscapes, and the specific details are shown in Table 2-11.

The subgrade of the project is used for the treatment of the sections with fixed and semi-fixed sand dunes, and the subgrade design has to ensure that the subgrade can meet the requirements of critical height and minimum filling height to further ensure that the subgrade can stay in a dry state to prevent the occurrence of frost damage. The roads in this project are municipal roads. In order to ensure that the route is comfortable and the subgrade is stable, also taking into account the need for the sand transport in sandy and windy sections on the road, the filling and excavation slopes all adopt the 1:3.

In order to reduce the subsidence of the subgrade and ensure the strength and structural stability of the subgrade and pavement, the degree of compactness of fill must be strictly controlled to ensure that subgrade compaction meets the compactness standard stipulated in the design. The compactness of the soil subgrade shall meet the compaction standard stipulated in the Codes for Design of Urban Road Engineering (CJJ37-2012) (see the table below). The subgrade rolling must base itself on the best moisture content generated from the heavy compaction test as the control index for conducting the filling, while the quality control shall also be conducted at the same time. The minimum strength of the subgrade filler and the maximum particle size of the filler should be consistent with the provisions in Table 2-12.

② The treatment of special subgrade

The K0+220-K0+800 section of the old road subgrade of this project is the miscellaneous fill. When the subgrade strength can not meet the requirements, the treatment is the excavation of the miscellaneous fill and the replacement with the gravel soil. The widened part of the K1+400-K2+830 section is the farmland section, with the base of high water content. The treatment is the excavation of the foundation soil with excessive water content and the replacement with the gravel soil.

③ Subgrade protection engineering

The project adopts the rhombic frame slope protection for the road fill section with the height of fill being >4m.

③ Subgrade and road drainage

The C20 cast-in-place concrete shallow-dish-shape subgrade ditches are set in the excavation sectionsof the project.The pavement water is first collected and then drains off the subgrade through the drainage ditches or rapids troughs. The subgrade drainage of the road fill sections mainly features the scattered drainage.

4.1.2 Pollution Sources of Construction Exhaust Gas

Exhaust gas generated during the construction period includes construction dust, exhaust gas from construction machinery and asphalt fume generated from road pavement. All of these are subject to the unorganized discharging and dispersed in the construction site and along the proposed road to be rebuilt.

(1) Construction dust

Construction dust mainly comes from dust of construction site, unorganized dust generated from the dumping, stacking and transportation of road materials, and exhaust gas of construction machinery.

① Unorganized dust at construction site

Unorganized dust at the construction site includes wind-driven dust from earthwork unloading, outdoor storage yard and exposed areas. The dust amount during earthwork unloading can be calculated according to the empirical formula proposed by the Environmental protection Research Institute of Shanxi Province and Wuhan Institute of Shipping Engineering, the empirical formula is:

M Qe=0.61u 13.5

Where: Q - dust amount when unloading materials, kg/time; u - average wind speed, m/s, take 2.5m/s; M - truck unloading volume, t, calculated by 10t.

Calculation results: Q = 3.37kg/time.

Due to the construction needs, temporary stacking and storage of powdery building materials such as lime, sand and the like may cause dust when the climate is dry and

107

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project windy. Dust generation is related to such factors as local weather conditions, human activities, moisture content of dust.

② Road dust

The dust amount of the transportation of engineering vehicle can be calculated according to the empirical formula proposed by the Environmental Protection Center of Port of Shanghai and Wuhan Institute of Shipping Engineering, the empirical formula is:

0.85 VMP      QL=0.123          0.72  5   6.8   0.5 

Where: Q - dust amount when truck running, kg/time;

V-truck speed, km/h, take 20km/h;

M-truck capacity, t, calculated by 10t/vehicle;

P-material volume on the road surface, kg/m2.

Calculation results: Q = 9.41kg/vehicle.

(2) Exhaust of construction machinery

The construction machinery used in the construction mainly includes road rollers and pavers which use diesel. Such machinery will generate a certain amount of exhaust gas, including CO, NOx and SO2, etc., and the amount produced is connected with construction methods, construction machinery power, operation conditions and other factors.

(3) Asphalt fume

Paving asphalt in this project is purchased directly from the asphalt mixing station, rather refined and stirred at the site. The asphalt fume is mainly produced during the road paving, but the asphalt adopted in this project doesn't need heating, which reduces the amount of asphalt fume that is produced when refining and stirring at the site and relieves impacts of asphalt fume and Benzo [a] Pyrene on peripheral protection targets.

4.1.3 Waste Water during the Construction Period

108

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project

The main waste water sources during construction period include the domestic sewage of the construction workers and the construction wastewater. (1) Domestic wastewater: The maximum worker number of on-site construction of both roads in this project is 80, and the construction period is 24 months. The water use standard of construction workers is 20L/(person/d), the discharge coefficient of sewage is 0.8, so the amount of domestic wastewater generated during construction is 1.28m3/d (921.6m3). With reference to similar projects, the concentrations of CODCr, BOD5 and SS in domestic sewage during construction period are 300mg/L, 150mg/L and 150mg/L respectively. The discharge of domestic sewage during the construction period is shown in Table 4-2. Table 4-2 Discharge of Domestic Wastewater during Construction Period Discharge amount Index Discharge concentration (mg/L) (m3/construction period) Domestic wastewater during / 921.6 construction period 0.28 CODCr 300 0.14 BOD5 150

SS 150 0.14

The temporary latrine pits are set up during the construction period. The construction wastewater is mainly from washing wastewater used by construction workers. The quality of the washing waste water is good. The waste water in the canteen should be poured into the construction site together with washing wastewater through the sedimentation treatment in the grease trap in order to reduce dust. (2) Construction wastewater: Construction wastewater includes cooling water and flushing water for the operation of machinery and equipment, as well as oily water which is directly discharged without any treatment generated during the operation of construction machinery or generated during construction machinery maintenance. The construction wastewater shall be recycled rather than discharged after sedimentation treatment. 4.1.4 Solid Waste During the Construction Period

The main solid wastes during the construction period include spoil and stone generated by earthwork excavation, construction wastes generated by house demolition and domestic wastes generated by construction workers. 109

(1) Abandoned earthwork

According to the information provided by the construction side, the remaining earthwork of the road construction from Gulang County to Shuangta Industrial Park is 3 92,353 m . The remaining earthwork is transported to the soil spoil ground of 1.7km to the right of the road K3 + 460. The remaining earthwork from the road construction from the Xingxinxin Village of Xijing Town of Gulang County to S308 Route Line is 35,380 m3, surface-clearing earthwork is 109140 m3, and the remaining earthwork is transported to soil spoil ground of 0.25km to the right of road K3+110.

(2) Construction waste

Xingminxin Village of Xijing County of Gulang County-S308 Route Road Project in this project does not involve demolition. The demolition area of Gulang County-Shuangta Industrial Park Road Project is 150m2, the output of construction waste generated from project demolition can be calculated according to: brick-concrete structure 0.5t / m2, the wastes generated by construction demolition are about 75t. For the recyclable in the construction waste shall be classified and recycled, the rest shall be stacked in designated place in accordance with the construction waste clearance and transportation license issued by relevant departments.

(3) Domestic waste

The construction period of this project is 24 months. The output of domestic waste produced per capita is calculated according to 0.5kg/d • person. The maximum number of on-site construction workers in this project is calculated by 80 persons, so the output of domestic waste generated during the construction period is 28.8t. The domestic waste generated from two sites shall be transported to the local domestic waste landfill after intensive collection. The output of all kinds of solid wastes during the construction period is shown in Table 4-3. Table 4-3 List of Output of Solid Waste Generated during Construction Period

4.1.5 Impact on Ecological Environment During the Construction Period

(1) Impact of project land occupation on land use The stacking of spoil and surface excavation during the construction period of the project causes the bare surface. If not treated in time or taken mitigation measures, a certain amount of soil erosion will be caused.

At the same time, due to the unreasonable stacking of building materials and spoil during construction period, the earthwork that may be lost may has impact on the environment.

(2) Vegetation deterioration and agricultural impact

According to the survey, there is no basic farmland along the construction road of this project, the construction of this project will not cause the damage to arable land. After completion of the project, the road traffic network will be improved, promoting land use value of surrounding villages. The construction of the project conforms to the planning requirements.

4.1.6 Impact of Construction on the Social Environment

The adverse impacts on the social environment during the construction period of this project is the transferring and stacking of a large amount of building materials as well as workers turnover, which will increase traffic volume and aggravate congestion in the construction area, disturb the existing traffic and affect the travelling and safety of residents along the line. At the same time, land occupation will also have a certain adverse

111

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project impact on the villagers' life. There is no sensitive spot around the Xingminxin Village of Xijing County of Gulang County-S308 Route Road Project, which poses minor impact on the social environment; There are many sensitive spots around the road from Gulang County to Shuangta Industrial Park, which will produce some impacts on surrounding residents during the construction period. This environmental impact assessment requires the construction unit to standardize the construction during the construction period, and to regularly maintain the construction machinery and intermittently use strong-noise equipment to reduce the impact on sensitive spots. Due to the linear project and moving construction working surface, significant impacts will not be produced on a certain sensitive spot. And with the end of the construction period, the impacts of construction on the surrounding environment will disappear.

4.2 Analysis of Pollution Source during Operation Period

The Pollutants during the operation period of the project mainly generated during vehicle travelling. The analysis of the technological process during the operation period is shown in Figure 4-2.

4.2.1 Noise

The noise pollution sources during the operation period are mainly traffic noise, an unsteady noise source. Noise source prediction adopts NoiseSystem V3.0 software. After inputting the traffic volume and designing the vehicle speed, the noise source intensity at a distance of 7.5m from the vehicle can be calculated. The calculation results are shown in Table 4-5.

4.2.2 Atmospheric Pollution Sources

113

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project

Motor vehicle exhaust contains more complex components, of which the main pollutants include CO, NOx and CHx. By comparing with the similar reports, the above pollution sources are linear and mobile. For urban roads, automobile exhaust has a greater impact on roads within 20 ~ 50m, and impacts gradually decrease as the distance increases beyond 50m.

In addition, car tires will raise the dust by touching the road surface, which causes a secondary dust pollution. The delivery of materials containing dust will also cause dust pollution due to scattering and blowing and other reasons.

This assessment mainly considers the impact of automobile exhaust on the environment.

According to the Article 7, No. 144, Notice of Gansu Province on the Implementation of the Measures for the Elimination of Heavy-polluting Vehicles and Old and Scrapped Motor Vehicles that Fail to Meet the Targeted Exhaust Emission Standards, G.Z.B.F [2014], cities (prefectures) and counties (cities and districts) at all levels should actively coordinate to reduce nitrogen oxide emissions from motor vehicles by improving fuel quality. By the end of 2014, Gansu Province has fully implemented the Fourth Stage of the National Emission Standards for Motor Vehicles and fully supplied the motor gasoline and diesel according to the Fourth Stage of the National Emission Standards for Motor Vehicles. This project shall implement the Fourth Stage of the National Emission Standards for Motor Vehicles in every feature year.

According to the Environmental Impact Assessment Code of Highway Construction Project, the intensity of gas pollutant emission of automobile exhaust can be calculated as follows:

k −1 Q j = 3600 Ai Eij i=1

Where: i ------stands for car classification including big, medium-sized and small vehicles;

Ai ------stands for the hourly traffic volume of i-type vehicle in the predicted year, vehicle/h; 114

Eij ------stands for the single vehicle emission factors of j-type pollutant from i-type vehicles under highway operating conditions, mg/(vehicles .m);

Qj ------stands for the intensity of pollutant emission of j-type gas, mg/(m.s).

The emission sources of automobile pollutants during the operation period are estimated with reference to the recommended values of Integrated Emission Factor of In-use Vehicles, as shown in Table 4-6.

Table 4-6 Eij Recommended Values of Single Vehicle Emission Factors of Vehicles (g / km · vehicles)

The road surface runoffs of the proposed road will depend on the amount of rainfall.

115

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project

The mean annual precipitation of Gulang County (the site of road engineering) is 361.3mm, the area of surface gathered water is about 180,600m2, and the runoff coefficient is 0.7, so the output of road surface runoffs will be 6.55×105m3/a. With reference to the water quality test of surface runoffs on the domestic roads, the road surface runoffs can be determined as the average value of all pollutants within 120min: pH7.4, CODCr 10.7mg/L, petroleum 7.0 mg/L, SS 280 mg/L.

5.1.1 Construction Noise Prediction Mode

116

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project

The noise during the construction period is mainly from construction equipment, mostly discontinuous noise. The noise source intensity is between 85 and 100 dB (A). The noise-producing equipment is placed outdoors.

According to the point source attenuation mode, the noise attenuation distance can be calculated, the formula is:

L2=L1-20lgr2/r1-△L

Where: L1, L2- stand for the noise level values at distances of r2, r1 from the noise source, dB;

r2, r1- stand for the distance from noise source, m;

△ L - stands for noise reduction level after other attenuation, dB (A)

The total sound pressure level after superposition of multiple noise sources is calculated as follows:

 n Li  L = 10lg  1010  总    i=1 

Where: n - the total number of noise sources;

Ltotal - the total sound pressure level at a certain point.

5.1.2 Prediction and Assessment of Construction Noise

As the construction unit has not been able to provide the construction plan, by referring to similar projects, the main construction machinery used for a construction operation area in different construction stages of this project are generally as follows:

① Subgrade construction stage: 1 loader, 1 excavator, 2 trucks, 1 bulldozer.

② Pavement phase: 1 land leveller, 1 road roller, 2 vibrating spears.

According to the noise level of highway construction machinery in Table 5-1, the total superimposed noise level of the construction working surface at different construction stages is calculated as shown in Table 5-2.

According to the prediction results in Table 5-2, in the absence of prevention and control measures, in order to achieve the requirements of Emission Standard for Ambient Noise from the Construction Site Boundary (GB12523-2011 (70 dB (A) in daytime and 55 dB(A) in nighttime), the required attenuation distance during the subgrade construction shall be 85m in daytime and 500m in nighttime. The required attenuation distance during road pavement phase is 74m in daytime and 410m in nighttime. If taking the road range within the red line as the construction boundary, the boundary distance will not meet the attenuation distance required by construction noise.

In this project, there is no sensitive spot around Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project. The impact of external noise in the

118

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project

different stages of construction period on surrounding sensitive spots is mainly concentrated in the villages along the Gulang County-Shuangta Industrial Park Road Project. The prediction values of background noise by superimposing noise during the construction are shown in Table 5-3.

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project

According to the prediction results in Table 5-3, the contribution value of noise to surrounding sensitive spots during the construction period of this project is larger than the self-noise background value of sensitive spots. The noise values after the superposition all exceed the standard regulated in World Bank EHS Environmental Quality Standard (GB3096-2008). Therefore, the above prediction results show that road construction will impose great impacts on the acoustic environment of road sensitive spots of this project, especially at night, which fails to meet the function division requirements of the corresponding acoustic environment. Therefore, the EIA requires the construction unit to set 2.5m-high hoarding on both sides of the road in the subgrade stage, post notices at all sensitive spots in the pavement stage and prohibit construction at night, which will reduce impacts of construction period on acoustic environments of surrounding sensitive spots to a minimized extent.

5.2 Assessment of Impact on the Ambient Air during the Construction Period

5.2.1 Dust at the construction site

According to the survey and measurement carried out by Beijing Municipal Environmental Protection Bureau on the dust of four municipal engineering (two works with hoardings and two without hoarding), the measured wind speed was 2.4m/s (the average wind speed in the project area was 1.7m/s), the results are shown in Table 5-4.

Average / 1024 626 435 421 419 419 /

According to the data in Table 5-4, the scope and degree of impact on dust generated by municipal engineering are as follows:

(1) The pollution of construction dust without any hoarding is very serious. The average concentration of TSP at 20m downwind direction of the site is 1503 μg/m3, which 2 is 3.7 times that of the control point, equivalent to 5.01 times that of the daily mean standard (0.3mg/m3) of TSP Level II in the Ambient Air Quality Standard (GB3095-2008).

(2) The pollution of construction dust with hoardings has been relatively improved when compared with that without any hoarding, but it is still serious. The average TSP concentration at the downwind direction at 20m away from the site is 1024μg/m3, which is 2.44 times that of the control point, equivalent to 3.41 times that of the daily mean standard (0.3mg/m3) of TSP Level II in the Ambient Air Quality Standard (GB3095-2008).

(3) Hoardings have obvious effect on alleviating the dust pollution of municipal construction and reducing the TSP concentration in the downwind direction by about 25%.

It can be seen that the construction hoardings can effectively reduce the impact of dust of the construction site on the surrounding ambient air quality. After the construction hoardings are adopted, the concentration of construction dust can basically reach the concentration value of upwind control point at 150m. Therefore, this project requires the 121

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project installation of hoarding, which will greatly reduce the impact of dust on the surrounding ambient air. At the same time, the average wind speed at the project site is 1.7 m/s, and the impacts of dust during the construction period shall be less than that of the analogical project.

5.2.2 Dust from Vehicle Transportation

According to relevant information, the dust generated by the transport vehicles traveling on the construction site accounts for about 60% of the total construction dust, which has a great relationship with the site conditions. The dust generated in the site under the influence of natural wind generally affects the area within 100m.

In order to restrain the dust of vehicles during construction, dust suppression by uninterrupted watering is usually carried out every day on the road surface on which the vehicles run over, which can reduce dust by 70%. The dust suppression experiment results are shown in Table 5-5.

Table 5-5 Experiment Results of Dust Suppression by Watering on Construction Site

Distance (m) 5 20 50 100

Hourly No watering 10.14 2.89 1.15 0.86 concentration of TSP (mg/m3) Watering 2.01 1.40 0.67 0.60

The above experimental results show that the uninterrupted watering can be implemented on the construction site every day, and the distance of TSP pollution caused by vehicle dust can be reduced to 20 ~ 50m. At the construction site of this project, except for construction transport vehicles, other vehicles are prohibited from entering and exiting. In addition, the local soil is relatively wet, the dust generated by transportation vehicles at the construction site will not cause too much impact on the surrounding environment as long as watering dust suppression are carried out in the dry and windy weather.

5.2.3 Dust of Excavation and Material Storage Yard

Through analogical investigations, the maximum dust when conducting the excavation is about 1% of the excavated soil volume when the protective measures are not 122

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project taken and the soil is relatively dry. The dust amount during excavation is about 0.1% and the dust during excavation has less impact on the surrounding environment when certain protective measures are taken (such as controlling the excavation face, water watering timely., etc.) and the soil is relatively wet.

Materials at the construction site, temporary stacking of spoil and stone will produce dust. According to statistics, dust emissions are 0.12kg/m3 material. The emissions can be reduced by about 90% if materials are covered with canvas or water spraying are carries out to suppress dust.

5.2.4 Analysis of Impact of Other Exhaust Gases on the Environment

(1) Analysis of impact of exhaust gas from construction machinery on environment

Construction machinery used in this project mainly includes excavators, loaders, bulldozers, land levellers and other machinery. All of them will generate a certain amount of exhaust gas during operation. Considering that their emissions are relatively small and their impact scope is relatively partial, the environmental assessment requires the construction unit to adopt high-quality oil and strengthen equipment maintenance and management to reduce exhaust gas amount from construction machinery and transport truck in operation.

(2) Impact of asphalt fume on environment

The road pavement of this project adopts commercial asphalt, which will produce asphalt fume during pavement laying. Asphalt fume contains THC and more pentacyclic and hexacyclic organic substances, many of which are carcinogenic substances, such as benzopyrene, benzanthracene, benzophenanthrene, pyrene and other pyrenes, and would impose greater impacts on human health. Taking benzopyrene as an example, the content of benzopyrene in common asphalt is 0.1-27mg/kg, and the content of benzopyrene in asphalt road pavement can reach 93mg/1000m3.

As the space is rather open around the project and there are fewer environmental sensitive spots along the route, the asphalt fume produced is easy to diffuse and dilute. As a result, the emission amount of asphalt fume during the construction period of this project is relatively small, which has a relatively small impact on the environment and 123

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project sensitive spots of the operation area.

5.3 Analysis of Impact on Water Environment during Construction Period

5.3.1 Domestic Sewage Generated by Construction Workers

The sewage output generated by the project construction workers is about 1.28 m3/d. The amount produced is rather less and the quality of water is good. The domestic sewage produced in the construction campsite can be directly splashed to the construction site along with other domestic sewage after sedimentation treatment in the grease trap to suppress dust. Domestic sewage has little effect on the environment. 5.3.2 Wastewater of Vehicle Cleaning

The oil concentration of wastewater after cleaning vehicles is 10 ~ 50mg/L. Such waste water can be recycled after the oil insulative deposition. The isolated oil can be to a qualified processing unit for processing after collection.

After adopting various prevention and control measures to treat waste water, the domestic sewage of construction workers and waste water from cleaning vehicles will not cause pollution to the water environment.

5.4 Assessment of Impact of Solid Waste on Environment during Construction

The solid waste generated during the construction period mainly includes the spoil caused by excavation of earthwork, the construction demolition waste and domestic waste of construction workers.

According to the earthwork balance analysis of the project, Gulang County-Shuangta Industrial Park Road Project will leave remaining earthwork of 92,353 m3 which will be transported to the spoil soil ground of 1.7km to the right of road K3+460. Xingminxin Village of Xijing Townof Gulang County-S308 Road Project will leave remaining earthwork of 35,380 m3 and surface cleaning earthwork of 109,140 m3 which will be transported to the spoil soil ground of 0.25km on the right side of the road K3+110. The Environmental Impact Assessment requires the construction unit to 124

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project carry out strict ecological restoration and management on the spoil soil ground, including planting green vegetation after leveling the soil borrowing ground to prevent dust pollution in adverse weather conditions.

The demolition area of Project is 150m2, the output of construction waste generated from project demolition can be calculated according to: brick-concrete structure is calculated by 0.5t/m2, the output of wastes generated by construction demolition are about 75t. For the recyclable in the construction waste shall be classified and recycled, the rest shall be stacked in designated place in accordance with the construction waste clearance and transportation license issued by relevant departments.

Domestic waste mainly includes a small amount of daily domestic waste generated by the construction workers. The output of domestic waste produced by construction workers during the construction period is estimated to be 28.8t. The construction unit shall set up a domestic waste bins at the construction site and entrust the environmental sanitation department to deal with the garbage after collection in order to avoid causing environmental pollution.

During construction period, timely collection, cleaning and transport constructions as well as domestic waste will not have a significant impact on the local environment.

5.5 Analysis of Impact on Land Use

The project is a new road engineering. The construction project is located in Gulang County, Wuwei City. The land area from Gulang County to Shuangta Industrial Park is 380.2 mu. The land occupation types cover wasteland, old roads and homesteads. Permanent land occupation will reduce the area of wasteland and the area of aboveground vegetation, which will lead to the change of land use structure during construction period and reduction of the economic benefits of agriculture and forestry in the region. Of course, the impact of the project construction on land use can be reduced through compensating for the permanently occupied wasteland by adopting the principle of occupation-compensation balance. The land occupied by Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project is deserted wasteland rather than farmland.

5.6 Analysis of Impact on Ecological Environment

The project road engineering from Gulang County to Shuangta Industrial Park is one of urban main roads. The both sides of this project does not belong to the scope of the basic ecological control lines. The rare animals and plants as well as ecological sensitive targets are not found in the surrounding area. Therefore, the impact of this project on ecological environment is mainly manifested in two aspects: ① The destruction of surrounding vegetation by the project construction; ② The impact of the construction process on the animals along the project.

5.6.1 Analysis of the Impact on Vegetation along the Project

The road engineering has certain occupying pressure on the land along the line. After the site survey, the arable land is not involved in the project. The ecologically sensitive area belongs to the general area, with a simple type. The area along the project has low vegetation coverage and simple vegetation, without involving such ecologically sensitive area as large-scale national forest parks, nature protection area and scenic spots. The surface vegetation along the road are common species with wide growth range and strong adaptability. Therefore, the project construction will have little impact on the regional vegetation and will not cause species extinction and changes in terms of plant type and structure. The construction boundary should be strictly controlled in the process of construction so as to minimize the destruction of plant population and resources and reduce the adverse impact of the construction on vegetation.

5.6.2 Analysis of the Impact on Animals along the Project

The area along the road from Gulang County to Shuangta Industrial Park is mostly human activity area without animal habitat basically. The location of road engineering of Xingminxin Village of Xijing Town to S308 Line is located on the edge of the desert. Based on the field survey, the ecological environment of this section is rather simple, without any animal habitat basically. Therefore, the project poses less impacts on the animal along the line.

5.6.3 Ecology Recovery Scheme of Soil Spoil Ground

The project sets a soil spoil ground at the 1.7km to the right of K3+460, with a land 126

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project area of 63.92 mu, the land type is flood land with a simple surrounding environment; The project sets a soil spoil ground at the 0.25km to the right of K3+110, which is located at the edge of desert with a simple surrounding environment. The soil spoil ground shall be level roughly without leaving cavities or pits in operation. The side slope degree of ground shall be gentle. The ground shall be filled by using bottom-up layered filling, with a thickness of 3 ~ 5m for each layer. The road shall be built until to the slope surface before filling of each layer, and then residues shall be discharged down the slope, and promptly bulldoze residues with a bulldozer. In order to prevent eroding slope by rain, a counter-slope facing to ditch shall be formed after bulldozing, and residue-discharging from top to bottom is prohibited.

Closure measures of soil spoil ground: After the construction, the soil spoil ground need to be closed. The closure greening of closure protective layer and the vegetation layer should be coordinated with the surrounding landscape and plants should be arranged according to the thickness of the soil layer, soil properties and climatic conditions. Trees with strong root penetration shall not applied in the course of closure greening. The soil spoil ground adopts mortar rubble gravity retaining wall protection, bulldozing and earthing, reclamation and greening.

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project

It can be seen from the above atmospheric prediction results that the hourly concentration, daily average concentration and annual average concentration of NO2 meet the standard limits of Level II of the Ambient Air Quality Standard (GB3095-2012) during each operation period. The hourly concentration and daily average concentration of CO all meet the standard limits of Level II of the Ambient Air Quality Standard (GB3095-2012). Generally speaking, the operation period of this project will not have a significant impact on the ambient air quality. Xingminxin Village of Xijing Town of Gulang County- S308 Route was designed as urban secondary road. The actual traffic volume after the completion of the road is far less than that of road from the Gulang County to Shuangta Industrial Park. According to the above predictions, the exhaust gas pollutants generated during the short-term, mid-term and long-term road operations of Gulang County to Shuangta Industrial Park have less impact on the surrounding environment. Therefore, it can be concluded that the operation periods of the Xingminxin Village of Xijing Town of Gulang County-S308 Route have less impact on the surrounding environment.

6.2.2.2 Prediction Point and Prediction Section

(1) Discrete point

This assessment predicts that the discrete points select the five existing protected targets within the assessment scope of this project. The predicted sensitive spots are shown in Table 6-25.

(2) Horizontal prediction section

Without considering the altitude difference, the distribution of buildings on both sides of the road, a total of two horizontal prediction sections are established.

Section 1: Set at 0 ~ 200m to the north of the boundary, the step length of the line segment is 10m and the predicted height is 1.2m.

Section 2: Set at 0 ~ 200m to the south of the boundary, the step length of line segment is 10m and the predicted height is 1.2m.

6.2.2.3 Prediction contents

(1) According to the predicted traffic volume of this project, the horizontal sound field can be predicted within 200m on both sides of the road only after considering the contribution of traffic noise in the ideal section (i.e. without taking the building insertion

135

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project noise loss into account) after the completion of the road. After that, the isogonic sound chart could be drawn and the traffic noise protection distance could be given.

(2) After the project reaches the designed traffic flow, the corresponding acoustic environment background values are superimposed by the predicted traffic noise values to predict the acoustic environment quality of each objectives of environmental protection.

6.2.2.4 Impact Prediction and Analysis of Acoustic Environment (Impact Prediction of Acoustic Environment with Sensitive Spots)

The prediction value of impact of the project on sensitive spots=the noise contribution value of the project + background value.

According to the current status of the project and the current quality status of the surrounding environment, the current status monitoring value includes the contribution of the current traffic noise which can not represent the noise background value at the sensitive spot. By analyzing the current situation of the surrounding environment of the project and the distribution of each sensitive spot, the noise background value of the sensitive spot of this assessment selects the maximum value of the current monitoring value of noise to represent the noise background value at each sensitive spot of the project. Some road sections of this project are characterized by high subgrades, and the vehicle noise generated when running on high subgrade sections is slightly larger than the normal noise level. However, by considering that there is no school or hospital or other sensitive plots around the project, traffic volume is generally not large and the altitude difference between sections with high subgrades and general road is not big, so the prediction results are reasonable in accordance with the normal situation.

After the completion of the project, the traffic noise has a certain impact on the surrounding acoustic environment quality. According to the prediction results in Table 6-29, it can be seen that after the background value is superimposed, there emerge violation in sensitive spots of Donggou, Weijiadazhuang and Zhangjiamo in the nighttime during the mid-term operation of the project, showing that the mid-term operation (in 2026) of the

138

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project

road in this project will impose certain impacts on the acoustic environment of sensitive spots. Therefore, this EIA requires the construction unit to actively monitor the current status during the operation period. In the event of any violation, the construction unit should take timely noise prevention measures such as the replacement of double glazing of sensitive spots, so that the impact of noise on the surrounding sensitive spots will be reduced to a minimum. ③ Noise prediction of sensitive spot during long-term operation ( in 2034)

After the completion of the project, the traffic noise has a certain impact on the 139

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project surrounding acoustic environment quality. According to the prediction results in Table 6-30, it can be seen that after the background value is superimposed, the noise standard in Chenjiazhuang, Donggou, Weijiadazhuang and Zhangjiamo exceeds the standard regulated by World Bank EHS in the nighttime, particularly, the noise value of Weijiadazhuang exceeds the standard both in the daytime and nighttime. Therefore, this EIA requires the construction unit to actively monitor the current status during the mid-term operation. In the event of any violation, the construction unit should take timely noise prevention measures such as the replacement of double glazing of sensitive spots, so that the impact of noise on the surrounding sensitive spots will be reduced to a minimum.

④ Summary of noise prediction of sensitive spots

In conclusion, after the completion of the project, the traffic noise has a certain impact on the surrounding acoustic environment quality. According to the above prediction results, it can be seen that in the short-term operation, there is no violation in each sensitive spot after the background value is superimposed during the project operation, meeting the limit regulated by World Bank EHS Environmental Quality Standards, namely, 55dB (A) in the daytime and 45dB (A) in the nighttime. However, during the mid-term and long-term operation, the noise at a number of sensitive spots begins to exceed the standard. During the long-term of operation, the noise in Weijiadazhuang exceeds the standard both in the daytime and nighttime. Therefore, the EIA requires that the construction unit actively carry out the current status monitoring during the mid-term operation. In the event of any violation, noise prevention measures should be adopted timely, such as the replacement of double glazing of sensitive spots, so that the impact of noise on the surrounding sensitive spots will be reduced to a minimum. There is no sensitive spot around the Xingminxin Village of Xijing County of Gulang County-S308 Route Road Project and the traffic volume is rather small after the operation of the road, which poses the minor impact on the surrounding environment. 6.3 Analysis of Impact on Water Environment

The main water pollutants in the project operation period are road surface runoff. There are many factors affecting road surface runoff pollution, including rainfall, rainfall time, traffic volume, length of road section with pollutant carrying capacity, etc. In terms of road surface runoffs, SS and oil pollutants may exceed the standard, the remaining 140

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project indicators all meet the standard requirements. According to the local climate survey, there is less rainfall in the project area and there is no surface water near the two roads. The rainwater can be eliminated by natural evaporation, so the wastewater during this project operation period has less impact on the surrounding environment.

6.4 Analysis of Impact of Solid Waste on Environment

The roads to be built in this project are urban main road and urban secondary road. The solid wastes generated are mainly domestic waste generated by human activities. The domestic wastes are all put in the trash bins arranged along the roads, which would be cleaned and transported by the sanitation departments of Wuwei City daily, so the impact of solid waste on the surrounding environment will be rather less during the operation period.

6.5 Analysis of Impact on Social Environment

6.5.1 Impact on Local Social Development

(1) Improve the current status and structure of road network

The road engineering in this project is an important traffic main road for the overall planning of the city. The road is an important corridor for important municipal infrastructure in the urban area, mainly relieves the traffic flow in the urban area and serves the areas along the road. The road mainly plays the role of trans-regional fast track. Its completion and implementation will surely change the status of regional transportation, enhance the travelling transportation of residents and develop and promote the economic development of scenic spots.

(2) Speed up the development of Gulang County

The construction of this project, as the transportation infrastructure of the traffic main road in Gulang County, consolidates the development of modern industry and has a good promoting effect on the economic development of Gulang County.

(3) Enhance the urbanization level

The construction of this project will further relieve pressure on urban traffic, improve

141

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project the road network system, broaden the space for urban development, improve the overall functions of urban areas and improve economic development space, which will greatly enhance the urbanization level of Gulang County.

(4) Promote regional socio-economic development

After the project is completed and put into effect, the regional cooperation can be strengthened and the common regional development strategy can be implemented, which will promote regional social and economic development.

6.5.2 Analysis of Impact on Land requisition and Demolition

(1) Situation of land requisition and demolition

According to the feasibility research report of this project, the permanent land occupation implemented by Gulnag County-Shuangta Industrial Park road project reaches 380.2 mu involving the demolished brick concrete houses of 150 m2. The demolition will not involve the wells, greenhouses and graves. Xingminxin Village of Xijing County of Gulang County-S308 Route Road Project in this project does not involve demolition.

(2) Analysis of Impact on Land requisition and Demolition

Road construction will inevitably collect land and demolish houses, thus causing social problems such as relocation of population and labor force resettlement in the construction area.

(3) Analysis of Impact on Land requisition

Part of the households that have lost agricultural land due to the construction of this project will adjust the balance of the land allocation within the village. If the reduced quanlity of land after balance is relatively small, those households can be supplemented by relative economic compensation, which will not impose large impacts on their income source. However, if the life mode of residents in the construction area is affected and their income sources are changed by the project land requisition, the government needs to actively guide the people affected by the project to gradually shift to factories and enterprises to go on employment or engage in commercial activities, realizing smooth the transition of life mode in the long run.

142

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project

(4) Impact Analysis of Project Demolition

2 The land needing for demolition for this project reaches an area of 150m . Land requisition and demolition will affect the livelihood of residents in demolished areas. Therefore, demolition and land requisition will change the economic structure in some areas and affect the living and production activities of some residents. If handled improperly, it will bring about certain social problems . Therefore, it is necessary for government departments to formulate appropriate and realistic resettlement plans to protect the rights and interests of residents whose lands have been demolished and requisitioned. Generally speaking, the social and economic conditions of demolished and requisitioned land should be improved and the living standard of residents should not be lowered but guaranteed .

6.5.3 Analysis of Impact on Road Traffic Safety

In recent years, with the rapid development of rural economy and urban-rural integration, the construction of road network has been continuously improved, traffic conditions have been significantly improved, and the number of motor vehicles has risen sharply. However, road safety problems have also become more and more prominent. The reasons of major safety hazards include that residents have less awareness of traffic safety, lack of compliance with traffic safety laws and regulations, drive vehicles without a license and operate unlicensed motor vehicles on the road, motor vehicles do not participate in the annual inspection and compulsory mobile vehicle insurance, illegal passenger carrying, people and goods mixed loading, which shows serious security risks.

This road project will set up normalized sidewalks and non-motorized lanes and optimize the design of crossroads. For example, crossroads should be designed for canalization, zebra crossing design should be optimized, traffic signs should be added, traffic lights and deceleration strips should be set at intersections, pedestrian overpasses should be added to improve road traffic safety. At the same time, in terms of the road management, the greater supervision shall be carried out and violation shall be regulated to ensure safe and clear sidewalks, roads and other roads. By taking the above measures, the road safety can be improved to a maximize extent.

the environmental impact analysis article, there is no violation in each sensitive spot

during the short-term operation of this project, but there emerge violations in the mid-term

and long-term operation. The construction of this project will have a certain impact on the

surrounding acoustic environment. According to the relevant planning, Gulang County

will construct road network in the future. For the sensitive spots involved in this project,

there is no plan to build roads in the surrounding areas. Therefore, this EIA requires the

construction unit to actively carry out acoustic environment quality monitoring in the

mid-term and long-term operation, adopt positive noise prevention and control measures

for the protected targets with voilations in order to minimize the impact of acoustic

145

6.6.4.2 Analysis of Cumulative Impact on Ambient Air

It can be seen from Table 6-31 that there is no violation in each protected targets by monitoring the current acoustic environment, indicating that the past activities of the project location have less impact on the surrounding environment. As can be seen from the environmental impact analysis article, there is no violation in each sensitive spot during the short-term, mid-term and long-term operation of this project, which shows that this project will have a less impact on the surrounding ambient air. However, with the continuous development of the city, and the constant improvement of the road network in the urban planning, the entire ambient air of Gulang County will change to a certain extent. However, taking into account the planning in the Urban Planning of Wuwei City

(2015-2030) and the Implementation Plan for the Core Areas of Urban and Rural

Convergence and Development in Gulang County, the amount of construction to be constructed in Gulang County is generally small. Gulang County possesses flat terrain and excellent meteorological conditions, which is conducive to the proliferation of automobile exhaust. Generally speaking, the overall environmental air quality in the future will be less impacted.

The construction road of this project is urban main road. The common dangerous goods for highway transportation in the project area are petroleum, liquefied gas, pesticide fertilizer, fireworks and crackers, explosives and chemical raw materials, etc.

8.1.2 Possible Risk Accidents in this Project

161

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project

In view of the function, nature and surrounding environment of the road, the risk accidents occurred in this project are risks arising from the transport of dangerous goods.

The risks occurred in transporting dangerous goods mainly include the serious traffic accident occurred in transport and the dangerous goods leak due to traffic accidents and the violation of the stipulations of dangerous goods transport, so that dangerous goods carried directly into the water and the air near this project, resulting in vicious pollution accident.

The main possible risk accidents in the project are the following:

(1) The crashes and rollover accidents of dangerous chemicals during operation period result in the chemical leakage; The leakage of chemicals to the atmospheric environment pollute the atmosphere.

(2) The crashes and rollover accidents of dangerous chemicals during operation period encounter open fire and result in fire and explosion of dangerous goods.

8.2 Source Term Analysis

8.2.1 Content of Source Term Analysis

Based on the set accidents listed in the potential accident analysis, the maximum credible accident is screened out. Source item analysis of the maximum credible accident shall be conducted.

8.2.2 The Maximum Credible Accident

The maximum credible accident of this project that influences the surrounding atmospheric environment is the leakage of dangerous chemicals caused by the major traffic accident and volatilize to the atmospheric environment.

8.3 Accident Frequency Prediction

(1) Prediction mode

The probability of dangerous goods transport accident is calculated according to the following empirical formula:

162

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project

P = (A • B • C • D • E) / F

Where: P - Traffic accident rate of the dangerous goods transport vehicles in a predicted year of the whole section of proposed road, times / year;

A - Probability of traffic accident (times/million vehicles · km);

B - the proportion of dangerous goods vehicles (%);

C - Average annual traffic volume of the sensitive sections in the predicted year, millions vehicles/year;

D - The mileage of the sensitive road (km);

E - The reduced proportion of traffic accidents after the completion of road construction;

F - Traffic safety factor of dangerous goods transport vehicles.

(2) Calculation parameters

The parameters in the formula are as follows:

A - Reference to the survey statistics of Midwest Institute of the United States' study of using speed difference method to assess traffic safety, taking A = 0.23 times / million vehicles· km;

B - According to the survey, trucks in this area accounted for less than 5% of traffic volume and dangerous goods vehicles accounted for about 5% of trucks. Therefore, the proportion of long-term dangerous goods in traffic volume was 5% × 5% = 0.25% ;

C - Take average annual predicted traffic volume of the whole section of the road;

D - take the mileage of the section in sensitive area;

E - take 50%;

F - take 1.5.

(3) Prediction results

163

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project

The calculation results are shown in Table 8-1.

Table 8-1 Prediction of Accident Probability Traffic Accident Probability of Chemical Year Dangerous Goods Transport (Times / Year)

2020 1.08 × 10-5

2026 1.13 × 10-5

2034 1.21 × 10-5

(4) Brief analysis of the accident impact

From the calculation data and analysis in Table 9-1, it can be seen that the traffic accidents probability of the dangerous goods transport vehicles in each predicted year after the completion of the proposed road is very low. Generally, the ordinary accidents and minor accidents in traffic accidents are in the majority, and there are few major accidents and extremely vicious accidents in the traffic accidents. Therefore, as for the traffic accidents of dangerous goods transport, the probability of chemical leaks, explosions, fires or the like arising from traffic accidents is very low.

8.4 Risk Analysis

The prediction results of the accidents probability of dangerous chemicals transport shows that the probability of road accidents occurred in 2034 after the project is completed is 1.21 × 10-5 respectively. Analysis of the data shows that there is a low probability of major traffic accidents that may cause pollution in the event of accidental transport of dangerous chemicals vehicles during road operation period. Although the probability of such accidents is low, it can be known from the cases of similar accidents at home and abroad that the impact is very serious and even shocking, which will endanger the lives and property of residents in the accidents area and seriously pollute the ambient air. There are a large number of villages along this project. Once the transport accident of dangerous chemicals occurred, the impact is serious, so we must improve prevention and prevent such accidents. 8.5 Risk Accident Prevention Measures

9. Scheme Comparison and Selection 9.1 Scheme Comparison and Selection between "Have Project" and "Haven't Project"

The implementation of the proposed project road engineering will have different degrees of negative impacts on residents' life, daily traffic and natural environment along the project in short-term with the construction of the project, but the construction period is a short-term action, these negative impacts will disappear with the completion of construction period; After the operation period, due to the traffic opening of road engineering, the road conditions have been improved and the number of vehicles has increased. As a result, residents, schools, hospitals, enterprises and institutions on both sides of the road will be influenced by noise of different degrees. By taking the relevant noise reduction measures, the above-mentioned negative impacts can be effectively relieved.

If there is no construction of road projects, the above negative impacts will cease to exist. However, the traffic conditions in Gulang will remain its original status, and the traffic level is still low and urban and rural areas are divided in the transportation service and management system. With the development of the city, traffic conditions are increasingly becoming the limiting factor in the development of local economy. The serious damage of the existing roads and the poor roadbed conditions lead to the traffic jam and the increase of automobile exhaust and noise. With the increase of vehicles every 172

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project

year, the impact is also getting worse day by day, which brings great inconvenience to the living and traveling of residents along the project and restricts the development of the city.

In the link of zero scheme comparison and selection of the evaluation, the issue of whether the construction should be constructed shall be analyzed and demonstrated from the perspective of environmental protection, as shown in Table 9-1.

10. Economic Profit and Loss Analysis of the Environmental Impact

10.1 Impact on Regional Economic Development

As the transportation infrastructure, this project's promotion to the regional national economy is mainly manifested in the fact that the project investment and construction activities will increase the output value of the national economy and stimulate economic growth. According to the research and calculation conducted by relevant units, if the infrastructure investment adds 1%, GDP will also increase 1%, which has a greater impetus to the development of the national economy if calculated on the basis of the investment multiplier theory. During the construction and investment period, in addition to the needs of a large amount of labor force, this project will also consume a large amount of building materials such as gravel, wood, cement, steel, asphalt, etc. The construction itself has promoted the development of related industries, thus stimulating the development of national economy in the region.

After the completion of the project, its promotion of the national economy will be long-term, slow, and is difficult to conduct quantitative calculation. Its impact mainly embodied in: the implementation of the project perfected the urban road network pattern, optimized the road network structure, improved the traffic capacity of the entire road network and improved the transportation convenience among the regions. The improvement of traffic location has confirmed the change of the potentiality of regional economic growth, and the potential of economic growth has finally induced the economic growth.

The impact of this project on population and employment in Wuwei City includes

183

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project two aspects: direct impact (short-term impact) and indirect impact (long-term impact):

Direct impact:

Direct impact assessment can be divided into two stages: construction period and operation period. During the construction period, the project needs a lot of labor force. Therefore, the implementation of the project has provided some employment opportunities and provided a channel for solving the problem of excess local labor force in the short term. At the same time, the implementation of this project will also consume a large amount of building materials such as gravel, wood, cement, steel, asphalt, etc. Construction itself has promoted the development of related industries and provided employment opportunities for workers engaged in these industries.

Indirect impact:

Indirect impact is mainly reflected in the project put into operation. Thanks to the improvement of transport conditions, the investment environment in city has been upgraded. The industrial development speed will be accelerated and the scale will be further expanded. This will provide ample employment opportunities for the surplus labor force in the region. The increase of employment will effectively improve the living standards and quality of residents. The construction of the project will also significantly improve the residents' travel conditions and provide them with a better development environment and development opportunities.

In addition, the construction of the project will inevitably occupy some land resources and negatively affect the production and living of residents in the areas along the route in terms of house demolition, noise and exhaust pollution, the division of residential areas and the blockage of the transportation during the construction period. When laying out routes, the project will take various measures to minimize the amount of arable land occupied, reduce the number of demolished houses and related facilities, complete noise prevention facilities and flyover bridges and organize the transportation during construction, striving to minimize the negative impact of project construction on production and living of residents along the route. The loss of residents along the route can be compensated by employment opportunities provided during the implementation of the project, and the reasonable compensation for land occupation and demolition shall be 184

12.1.2 Compliance of Industrial Policies

210

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project

This project is an urban road construction project. According to the Guiding Catalog of Industrial Structure Adjustment (2011 Edition) (Revised in 2013), this project belongs to the category of "Encouraged Projects"; XXII. Urban Infrastructure; 4. Urban Road and Functional Transportation System Construction" project. Therefore, the construction of this project conforms to the requirements of the national industrial policies.

12.1.3 Environmental Impact Prediction and Assessment

12.1.3.1 Environmental Impact Prediction and Assessment of the Construction Period

(1) Construction noise:

According to the prediction results, the contribution value of noise to surrounding sensitive spots during the construction period of this project is larger than the self-noise background value of sensitive points. The noise values after the superposition all exceed the standards of class 2 and class 4a regulated in Acoustic Environmental Quality Standard (GB3096-2008). Therefore, the above prediction results show that road construction will impose great impacts on the acoustic environment of road sensitive spots of this project, especially at night, which fails to meet the function division requirements of the corresponding acoustic environment. The construction unit should take measures to reduce noise, improve management and especially avoid the impacts of night construction on surrounding sensitive spots. For construction machinery that can not meet the requirements of attenuation distance, the night construction should be limited so as not to affect the night rest of surrounding residents.

(2) Construction dust and dust from vehicle transportation

The construction hoardings can effectively reduce the impact of dust of the construction site on the surrounding ambient air quality. After the construction hoardings are adopted, the concentration of construction dust can basically reach the concentration value of upwind control point at 150m. Therefore, this project requires the installation of hoarding, which will greatly reduce the impact of dust on the surrounding ambient air. At the same time, the average wind speed at the project site is 1.7 m/s, and the impacts of dust during the construction period shall be less than that of the analogical project.

211

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project

The uninterrupted watering can be implemented on the construction site every day, and the distance of TSP pollution caused by vehicle dust can be reduced to 20 ~ 50m. At the construction site of this project, except for construction transport vehicles, other vehicles are prohibited from entering and exiting. In addition, the local soil is relatively wet, the dust generated by transportation vehicles at the construction site will not cause too much impact on the surrounding environment as long as watering dust reductions are carried out in the dry and windy weather.

(3) Construction waste water:

The sewage generated by the project construction workers is about 1.28 m3/d. The amount produced is rather less and the quality of water is good. It can be directly splashed to the construction site to suppress dust. Domestic sewage has little effect on the environment. The oil concentration of wastewater after cleaning vehicles is 10 ~ 50mg/L. Such waste water can be recycled after the oil insulative deposition. The isolated oil can be to a qualified processing unit for processing after collection.

(4) Construction solid waste:

The solid waste generated during the construction period mainly includes the construction waste and domestic waste of construction workers.

During construction period, timely colleceantion, cling and transport constructions as well as domestic waste will not have a significant impact on the local environment.

12.1.3.2 Environmental Prediction and Analysis during Operation Period

(1) Acoustic Environmental Impact Prediction and Analysis

212

Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project

After the completion of project, the traffic noise has a certain impact on the surrounding acoustic environment quality. According to the prediction results, it can be seen that after the background value is superimposed, there is no violation on the class 2 sensitive spots during the operation period of the road, meeting the class 2 standards of Acoustic Environment Quality Standard (GB3096-2008), namely, 60dB (A) in the daytime and 50dB (A) in the nighttime.

(1) Prediction and Analysis of Exhaust Gas Environmental Impact

The operation period is mainly the impact of automobile exhaust discharge on the atmospheric environment along the route. The main pollutants in vehicle exhaust are carbon monoxide, nitrogen dioxide, soot, hydrocarbons and so on. According to the characteristics of wind farmland along the route and the prediction of the source intensity of air pollutants discharged from the road environment, it can be seen that there is less pollutant discharge of the proposed project during the operation period. According to the comprehensive results of the completed environmental protection acceptance survey report of the completed roads in recent years, the range and degree of impact of automobile exhaust on the environment is very limited, of which the dust emission mainly stems from the background of the environment and the contribution value of road dusting is small. NO2 does not exist excessive phenomenon.
