1.6 Assessment criteria 1.6.1 Environment quality standards
(1) Surface water environmental quality standards 7. Class III standards in the “Environmental Quality Standards for Surface Water” (GB3838-2002) is implemented for Yuxi River (within the scope of assessment of the Component), and the Class V standards is implemented for Jiazhuang River. The specific standard values are shown in Table 1.6-1.

pH value (dimensionless) 6~9 6~9
COD 20 40
BOD 5 4 10
NH 3-N 1.0 2.0
TP 0.2 0.4
Petroleum and the like 0.05 1.0
(2) Ambient air quality standards 8. According to the “Atmospheric Environmental Function Zoning of Wuhu Municipality (2013~2020)”, the component area is classified as Category II functional area, and Class II standards of “Ambient Air Quality Standards” (GB3095-2012) are implemented.
9. The World Health Organization (WHO) Air Quality Guidelines are recognized as international standards and are adopted by the World Bank Group’s EHS Guidelines. In addition to guideline values, interim targets (IT) are given for each pollutant by the WHO as incremental targets in a progressive reduction of air pollution. The WHO guidelines and corresponding PRC standards are presented in Table 1.6-2 .
10. From Table 1.6-2, it can be seen that: For TSP, there are PRC standards but no corresponding WHO guidelines. For PM 10 , PRC Class 2 annual average and 24-hour average standards meet WHO IT-1 guidelines (there are no 1-hour average standards or guidelines for either PRC or WHO). For PM 2.5 , PRC Class 2 annual and 24-hour standards meet WHO IT-1 guidelines (there are no 1-hour standards or guidelines for either PRC or WHO). 3 For SO 2, WHO only has a 24-hour average guideline (0.125 mg/m ), which is 3 slightly lower than the PRC standard (0.150 mg/m ). However, SO 2 levels are low in the component area, and the component will only contribute low levels of SO 2, so the very minor difference is inconsequential. For NO 2 ,the PRC standard is equivalent to the WHO annual average guidelines, there is no WHO 24-hour average guideline; and the 1-hour average PRC standard is equivalent to the WHO guideline.
For O 3, the PRC class I 1-hour average standard is equivalent to the WHO 1-hour average guideline and PRC 1-hour average class II standard is equivalent to the WHO IT-1 1-hour average guideline. For CO, there are PRC standards but no corresponding WHO guidelines.

11. Overall the PRC standards show a high degree of equivalency to the WHO guidelines or IT-1 values and are adopted for use in this IEE report. (3) Acoustic environment quality standards 12. Table 1.6-3 presents the relevant PRC Noise Standards compared with relevant international guidelines as presented in the EHS Guidelines. The classes within the standards are not directly comparable, but the PRC Category I standards are equivalent to WHO Class I
8
standards, Category II standards are less stringent than WHO Class I standards and Category II and III standards are stringent than WHO Class II standards. Because Category II standard is applicable to the component areas along the road alignment and Category I standard is applicable to the nearby sensitive receptors, Category II for component area and Category I for sensitive receptors are utilized in this IEE report. Class IV standards will be implemented for the range within 35 meters of the red line on both sides of the traffic trunk line, Table 1.6-3 PRC Environmental Quality Standards for Noise (GB3096-2008) and relevant international guidelines PRC Standards International Standards Comparison Leq dB(A) One Hour Leq dB(A) Category Day Day Night Night 06- 07-22h 22-07h 22-06h 22h 0: Areas needing extreme quiet, such 50 40 as special health zones WHO Class I: WHO Class I: Classes are not residential, Residential, I: Mainly residential; directly institutional, institutional, and cultural and comparable, but 55 45 educational: educational: educational PRC Class II 55 45 institutions standards exceed WHO II: Mixed residential, Class II commercial and 60 50 WHO Class WHO Class standards.

Table 1.6-4 presents the relevant PRC and international standards (US EPA, there no such WHO or EHS Guidelines standards) for on-site construction noise. The PRC standards are more stringent than international guidelines and are utilized in this IEE report. At sensitive receptors, the component will apply World Bank EHS Guidelines. The PRC’s Emission Standard of Environmental Noise for Boundary of Construction Site (GB12523–2011) regulates construction noise, limiting construction noise levels at the construction site boundary to 70 dB(A) in the daytime (06:00–22:00 hours) and 55 dB(A) at night (22:00–06:00 hours).

2.4 Construction plan 1. Preparation work
42. Preparation work includes restoration of the midline, leveling and cleaning of the site, and procurement and transportation of materials, etc. The procurement and transportation of materials runs through the entire construction stage. 43. Restoration of the midline: the “table of straight lines, curves and corners”, “table of road lands”, “table of control point results”, “table of pile-by-pile coordinates”, etc. provided by the design institute are used to restore the midline. 44. Leveling and cleaning of the site: Within the scope of road acquisition and temporary land occupation, except for physical objects designated for protection in the design drawings and
- 22 -
by the engineer, all trees (including stumps), shrubs, stones, garbage, wastes, fences, structures and all artificial or non-artificial obstacles above the ground should be removed. The cleared ground debris should be transported to the designated location for stacking. The stripped topsoil should be transported to the area within the scope of land occupation for central temporary storage, which will be used for land reclamation and greening of side slope, central separation zone, etc.
45. Material procurement and transportation: The subgrade soil is taken from the vicinity of the road and the transportation distance is relatively close. Other road construction materials basically need to be purchased. The variety, specifications and quality of various road construction materials should meet the design requirements. The subgrade of the whole road section is mostly the filling, which is generally borrowed nearby.
46. The materials are generally transported mainly by trucks, and local transportation method can also be used for some of the materials. The contactor needs to make reasonable arrangement and dispatching plan for specifications, quantity to be used and temporary storage area of various materials. 2. Subgrade works
1) Earthwork
47. The subgrade earthwork is mechanically constructed. Subgrade construction should be carried out strictly in accordance with the “Technical Specification for Construction of Highway Subgrades” and design requirements. Particularly, stratified inspection should be strengthened to ensure compaction of the fill by heavy-duty roller compactor and mechanized construction.
2) Protection and water drainage work
48. The water drainage work of subgrade is mainly composed of water drainage ditch and side ditch, etc., which should be carried out at the same time with the subgrade work. The subgrade protection work is mainly stone preparation and grouting work, which can be carried out after the implementation of the earthwork and last to the final stage of the Component. The construction of protection and drainage works should be coordinated with culvert works and greening works, and the greening and drainage system should be completed before rainy season. 3. Pavement works
49. Before the commencement of the pavement works, the quality of the subgrade construction (including elevation, degree of compaction, etc.) must be inspected and confirmed before the construction work proceeds.
50. The construction of the subbase will be started as the completion of the subgrade. The pavement work adopts asphalt concrete pavement, which should be carried out strictly in accordance with the design requirements of “Code for construction and acceptance of asphalt concrete pavement”. The materials of each structural layer of the pavement should meet the
- 23 -
design requirements, and the construction unit should conduct corresponding tests and provide data for the construction site in time to check the quality of the works at any time. 4. Culverts
51. The existing old culverts are mostly reinforced concrete box culverts, some of which are the culverts with reinforced concrete covers. The old culverts are in good condition and meet the requirements of the flow cross-section, but the lengths of culverts cannot meet the road width. In the design, the entrances of the old culverts (splayed wall, “—”-shaped wall) will be dismantled first, and extended by using the reinforced concrete box culvert. The elevations of the auxiliary roads in some sections are too low, when the culverts are extended normally, the filling height cannot meet the requirements of the specification. Therefore, the culverts with left and right extension need to sink to meet the requirements of the specification. To ensure the flow cross section, the extended culverts will be appropriately widened. The new culvert is connected with the old culvert by box culvert, and the settlement joint needs to be provided at the joint.
5. Cross works
52. In order to reduce the impact on the traffic of the crossed roads, the construction plan should be carefully arranged to shorten the construction period as far as possible.
6. Landscape greening
53. The green space should start from sight angle, visual effect and experience psychology of pedestrians and drivers, and create humanized urban space. Local native tree species shall be selected, and landscaping trees suitable for local growth will be used for afforestation and beautification.
2.5 Temporary facilities 54. Two borrow pits will be set for the Component, covering a total area of 7.23 hm 2, and the land type is cultivated land. The borrow pit is also used as a spoil ground. The spoil is used to renovate the borrow pit after borrowing and restore it to cultivated land.

61. It is shown in Table 3.2-1 and Table 3.2-2 that the impacts of the Component on environment is comprehensive and diverse, with long-term and short-term impacts. Because the
- 31 -
construction period is short, noise, wastewater and impact of exhaust gas generated during construction can be effectively controlled. Therefore, the adverse impacts are mostly reversible, short-term and controllable. During operation, the traffic and transportation will be greatly improved, and it will play an active role in promoting regional economic development, but it will still generate traffic noise and automobile exhaust gas, which affect the environment along the highway.

4 Environmental impact assessment and mitigation measures
4.1 The existing main problems 95. Though the National Highway G347 has completed the mergence of two roads and road upgrading, it also bears high traffic burden from motor vehicles, non-motor vehicles and pedestrians due to the fast urbanization and crowed shops on both sides of the road, and as well as the transverse traffic interference from intersecting village roads .
96. The drainage and irrigation ditches are distributed in the vertical and horizontal directions in the diked area on both sides of the existing road, which are all soil-based open ditches. Rainwater flowing through villages, farmland and other plots are collected into the open drainage ditches and ditch ponds.
Fig. 4.1-1 Drainage and irrigation water system along the old road
97. Independent confluence drainage pipes are set for the road section passing villages and towns, but the design standard of the pipes is low and there are no sewage treatment facilities. Rainwater and a little of domestic sewage are collected by the pipes and then discharged into nearby water bodies.
Fig. 4.1-2 Buried pipe trenches for the sections passing the villages and towns 98. The component will widen the existing road with auxiliary roads on both side to reduce
- 49 -
the transverse interference to the main driveway and meet the mixed traffic demand, ensure the rapid passage of the main driveway, and improve the traffic capacity and service level of the road and meet the needs of rapid growth of road traffic volume. At the same time, it will improve the surrounding water drainage and reduce the impact on water environment.
4.2 Analysis of main environmental impacts
4.2.1 Ecological impact 4.2.1.1 Impact on vegetation
99. Due to the long history of agricultural development in the component area, the native vegetation in the assessment area has been destroyed, and the existing vegetation is mainly planted forest and shrub herbosa.
100. The impact on the vegetation during construction mainly comes from three aspects: permanent land occupation, temporary land occupation, mechanical roller compaction and construction workers during the construction. Among them, the permanent land acquisition damage to vegetation is long-term and irreversible, while the damage of temporary land occupation and construction disturbance to vegetation is short-term and reversible.
1. Impact of permanent land acquisition
101. Land acquisition will damage the vegetation along the component area. Based on the survey on the current status of vegetation distribution, the types of vegetation directly affected by construction are mainly crops and planted forest.
(1) Loss of agricultural crops 102. Land to be acquired is mainly dryland, which will cause loss of crops, including wheat, cotton, beans, peanuts, rape and other vegetables. (2) Forest loss
103. A small amount of mountainous planted forest land will be occupied, and the lost forest is mainly the shelterbelt on both sides of the existing road. 104. In addition, construction activities will also cause damage to farmland and planted forest around the villages. The damaged tree species are mainly poplar, paulownia, Chinese scholar tree, willow and some shrubs. 2. Impact of temporary land occupation
105. The borrowing area will occupy a total land area of 7.23 hm 2, and the construction site will occupy a land area of 0.8 hm 2. The temporary works will occupy the cultivated land, damaging the existing crops in a short period of time. After the completion of the works, the temporarily occupied land needs to be re-cultivated. 106. During construction, dust generated by the transport vehicles will have a direct impact
- 50 -
on the growth of surrounding plants. The dust falls on the leaves of plants, which can block the pores and affect the photosynthesis of plants, so that the plants grow slowly or even die. In addition, the stacking of raw materials and vehicle oil spills will also contaminate the soil, which will indirectly affect the growth of plants. Therefore, proper mitigation measures need to be taken to avoid/minimize the impacts.
107. In summary, the impact of temporary land use on vegetation is temporary, and effective measures must be taken to ensure that the vegetation is restored for the temporarily occupied land as soon as possible.
4.2.1.2 Impacts on agricultural ecology
1. Impact of land acquisition 108. The component area includes plains and micro-hills, and is mostly cultivated land. Due to the constraints of the existing road route, it is inevitable to occupy a certain amount of cultivated land. The land occupation will reduce the absolute amount of cultivated land along the line, but the cultivated land occupied is relatively small. Therefore, the component will not change the current land use status of the area, and will not produce a significant impact on the local agro- ecology.
109. As for the permanent land acquisition, the impact is greater. Therefore, the IA should coordinate with the local government and affected persons (Aps), and provide proper compensation; conduct the trainings to those urbanized APs and help them to find new jobs to ensure the new income sources and livelihood standards. 2. Analysis of the impact on agricultural production
110. For APs whose farmland are directly occupied, the IA and the local government should take effective measures to directly compensate to the farmers, or directly allocate the land to them so that they can restore agricultural production as soon as possible.
111. Although the component has certain impacts on the local agricultural economy, the convenient transportation makes the transport-out of agricultural products easier, which is conducive to the sales of agricultural products, making the output of products of the non-acquired farmland accelerated, and the output value per mu increased. In addition, a considerable number of retail and other employment opportunities will also change the current situation of slow local economic development. The losses caused by the component to the local primary industry can be compensated for by promoting the development of related tertiary industries. 4.2.1.3 Impact on water body for agricultural irrigation
112. During the subgrade construction, if the temporary side ditches are not excavated concurrently in the rainy season, it is easy to cause erosion of the farmland and siltation of the irrigation channels along the line, especially during the construction of limestone subgrade bedding, lime may be washed into the nearby irrigation water bodies and farmland along the line during storms. If the construction materials stockyard does not take temporary protective
- 51 -
measures, the construction materials may be blown by the wind or washed by rainwater into the nearby water bodies and farmland; and if no protective measures are taken during the transportation process, the powdery construction materials will be blown to the nearby farmland along the line by the wind, all these factors can produce an impact on water body and soil along the line.
113. According to the feasibility study report, the construction period of the subgrade will be from late 2019 to 2020. During the period, the component may encounter one rainy season. Therefore, temporary windproof and rainproof measures should be taken for the material stockyard, and covering measures taken for the construction transporting vehicles to minimize the impact on soil and irrigation water bodies. The good topsoil of plough layer is most important for land reclamation work. Therefore, before the construction of the subgrade and at the temporary construction site, the contractors should strip, transport and centrally pile up the soil pf the surface plough layer. After construction completion, it should be used as greening soil or for land restoration and reclamation. 4.2.1.4 Analysis of the impacts on the water system and water conservancy facilities along the line during operation 114. The farmland irrigation facilities in the component area are developed. The impacts on rivers, water systems and water conservancy irrigation facilities along the line were taking into account in the design. A large number of culverts have been included in the design, which will minimize the impacts on the irrigation systems. After completion, the culvert system can maintain the agricultural irrigation system in the area. When the rainfall forms road runoff, the rainwater will all be discharged through the rainwater pipe system and will not be poured into the farmland. Therefore, the road runoff will not produce significant impact on the subgrade and farmland. 4.2.1.5 Impact on wildlife
115. As the original road corridor has existed for a long time, and the development along the road is relatively high, no animal passage is found to be occupied. Therefore, the impact on wildlife during implementation is mainly during construction.
a. Amphibians 116. Amphibians generally require water for their reproduction, and their eggs are produced in the water bodies of streams and ditches. They are usually active in the shelters from dusk to dawn, and they get through the hot or cold season in the manner of estivation or hibernation. They generally take insects as their main food sources. Fish, snakes, birds, beasts, etc. are their natural enemies. The impact on their reproduction is mainly human disturbance and possible water pollution caused by construction sewage. 117. The amphibians within the assessment scope are mainly lentic and terrestrial types. The lentic type (foraging for food in still water or slow flow): they are mainly distributed in the vicinity of the road sections where there is a water body around the component site, and in ponds and rice fields within the assessment scope. The main impacts on them are mainly from the oily
- 52 -
sewage and other sewage caused by the machinery operation and repairs around the water body, environment pollution caused by the discharge of the waste, and construction noise, hunting and killing by the construction workers, etc. which will force these amphibians to temporarily leave their habitats. Terrestrial type (looking for food on land): they mainly move on the land not far from the water bodies within the scope of the assessment and are closely related to human activities. They are widely distributed along the component site, and mainly rest in farmland, ditches and nearby grasses, and move around in the vicinity of water bodies. Construction activities, including noise will disturb them on the habitats and result in the leave of them. But, since the impact is short-term, and there are many similar habitats in the assessment area which can be used for the transfer of these species. After the completion of construction activities, the living environment of the amphibians will be gradually recovered. 118. The survey results show that Bufo gargarizans are the dominant species of amphibians in the assessment area, but they mainly inhabit in the dark and humid forest, grasses, farmland, river ditches, and vicinity of village houses, feeding on insects. During construction, they will move to the habitats away from the construction area, therefore, the construction will not pose a threat to their survival. The decline in the populations in the assessment area is temporary and recoverable. In general, the impact of construction on amphibians is short-term, and the temporary impact on their habitats is also reversible. b. Reptiles
119. Reptiles generally lay eggs in shrubs and stone crevices. Their breeding seasons are mostly in spring and summer. Some of them live in water, some live in the stone crevices on the land, and some live near the houses. The residential type is only Gekko japonicus. They mainly move around in the residential area within the scope of assessment, their habitats highly coincide with human activities, and their adaptability is very strong, so construction has almost no impact on them. In addition, because the existing road have existed for a long time, the reptiles such as lizards and snakes involved in the assessment scope are common species, which have already adapted to interference of human activities. They mainly inhabit in artificial or semi-artificial inhabits such as village forests, forest shrubs and farmland. They have a wide range of foods and feeds on insects, frogs, birds and rats. During the construction period, if the construction materials and spoil are poorly managed, they will change the turbidity and other physical and chemical properties of the water in the water area involved, making the living environment of the reptiles destroyed or even disappear. But they will migrate to non-construction areas, so their survival will not be threatened. In general, the reptiles may temporarily leave the construction area and move to similar habitats in the assessment area. The impact during the construction period is temporary. c. Birds 120. There are many bird species in the component area, among which the forest birds are the most, and their distribution is also wide. They are distributed in the forests at the edges of villages and the forest land at the edges of the waterfronts. Because forest birds are good at
- 53 -
flying, it is easier for them to find alternative habitats during the construction period, so the component has little direct impact on them. The impact is limited to the reduction of their range of activities and habitats due to construction activities. These impacts are limited to the surrounding forest land, so the scope of impact is small. 121. There are also a certain number of land birds in the assessment area, including birds such as pheasant, which have strong adaptability and wide distribution. They are distributed on forest land along the component area, the rural forest network, the edge of the residential area, and the farmland. The impact of construction is mainly illegal hunting and noise. Because the existing road has existed for a long time, most of the inland birds in the component area are the species highly adaptable to human disturbances. They are more often seen in the habitats such as villages and farmland. In the assessment area, many same or similar habitats can be found. The impact during construction is temporary. 122. Spring and summer are the breeding seasons for most birds. If temporary placement of construction materials during construction occupies their habitats, these activities will have certain impact on their spawning and nesting. Considering that there are similar habitat nearby, the impact of the component on the parturition of birds is short-term. Secondly, the high noise during construction should be avoided in the spring as far as possible to reduce the impact of noise on bird parturition. d. Animals 123. The animals in the assessment area are mostly the species of semi-underground type. They are generally small in body size, and they mainly forage for food on the ground, inhabit and avoid enemies in caves, and some of them also look for food underground. Representative species include hedgehog and grass hare, Apodemus agrarius, Mus musculus, Rattus norvegicus, yellow weasel and other species. They are widely distributed within the scope of assessment. A few species, such as Mus musculus and Rattus norvegicus, are closely related to human beings and are concentrated in the vicinity of urban settlements and farmland. Some rodents and rabbits like to move around in the scope of human activities such as villages and vegetable fields. 124. The noise, lighting and human disturbance during construction cause certain shrinkage of the habitat of the animals. The construction activities have certain impact on their activities and food sources, but the animals are all the species with strong mobility and wide eating habits. In addition, there are many alternative habitats in the vicinity of the component area, so it is easier for the animals to find habitats. The scope of impact on animals is small and the impact time is relatively short. Therefore, construction will not produce a major impact on animals, and they can migrate to similar habitats nearby. After the construction is completed, they can still return to their original habitats. However, the increase in human activities, construction noise, wastewater and exhaust emissions resulting from construction activities will also have an indirect impact on the animals in the assessment area.

4.2.1.6 Soil and water conservation
1. Present status of water loss and soil erosion 125. The component area belongs to the southern red soil hilly area. The Anhui Province Zone is the area for farmland protection and human settlement maintenance in the hilly land along the Yangtze River. The soil erosion type is mainly hydraulic erosion, and the hydraulic erosion in the component area is characterized by surface erosion and gully erosion. According to the “Soil and Water Conservation Plan of Anhui Province (2016-2030)” (Wan Zheng Mi [2016] No. 250), the current status of water loss and soil erosion at the component site is shown in Table 4.2-1.
Table 4.2-1 Present status of water loss and soil erosion in Jiujiang District
Area without Erosion area (km 2) Total area obvious (km 2) erosion Very Slightly Moderately Strongly Severely Total (km 2) strongly
870.65 869.83 0.69 0.09 0.03 0.01 0 0.82
Percentage 99.91 0.09 (%)
126. The main vegetation types along the existing road are farmland vegetation, roadside vegetation, herbaceous vegetation, etc. The greening on both sides of the road are mainly arbor and shrubs. According to the “Standard for Classification and Gradation of Soil Erosion” (SL190- 2007), the allowable loss of soil in the component area is 500t/km 2•a. There is basically plant or crop coverage in the component area, and the background value of the native soil erosion modulus is about 300~400t/km 2•a, which is slight erosion. 2. Analysis of soil The disturbed surface area for construction is 72.26hm 2, and the area of facilities for damaged soil and water conservation is 72.26 hm 2. Due to construction activities, the total amount of water loss and soil erosion may be 7139.96 t, including 926.86t of background water loss and soil erosion and 6211.30t of new water loss and soil erosion.
3. Soil and water conservation measures 127. A comprehensively plan for water loss and soil erosion prevention and control measures will be developed, focusing on taking prevention of water loss and soil erosion, vegetation restoration, improvement of the ecological environment within the scope of responsibility of the component for soil and water conservation, and ensuring normal and safe implementation as the ultimate goal; prevention of negative impact on the surrounding environment and safety at the starting point; and taking the main construction area and the borrowing area as the key points according to the results of analysis and assessment of soil and water conservation and the
- 55 -
prediction of water loss and soil erosion in the main engineering design, and combining the existing soil and water conservation facilities in the main engineering design at the same time so as to develop a complete protection system. 128. On the basis of the water conservation functional works of the component, corresponding measures shall be taken according to the terrain, geology and water loss and soil erosion characteristics of each prevention and control area to well do the water loss and soil erosion prevention and control works. Engineering measures will be taken to control large-area and high-intensity water loss and soil erosion, and greening will be implemented, which shall match the engineering measures to improve water conservation effect, reduce engineering investment, and improve the ecological environment. 4. Soil and water conservation prevention and control measures
a. Main engineering area Engineering measures: topsoil stripping and back-covering; setting of subgrade drainage pipes (ditch). Planting/greening measures: planting arbor and shrub vegetation on the road separation zone and on both sides of the subgrade. Temporary measures: Temporary blockage, covering and water drainage of topsoil.
b. Borrowing area Engineering measures: topsoil stripping and back covering, water interception and drainage, land consolidation, bank, etc. Planting/greening measures: Vegetation planting in accordance with landscape standards.
Temporary measures: temporary blockage with bagged soil around. c. Construction site Engineering measures: topsoil stripping, land consolidation.
Planting/greening measures: Planting shrubs and laying turf at the construction site.
129. Temporary measures: topsoil blockage; excavate temporary simple drainage ditch around the site, and connect it with the natural ditch, and set up sedimentation tank at the end of the ditch; hardening of the site with macadam. 4.2.2 Impact on surface water
4.2.2.1 Surface water impact during construction 130. During the construction, the impacts mainly include construction wastewater and domestic sewage on the surrounding surface water. 1 Construction wastewater
- 56 -
131. Construction wastewater mainly includes oil from construction machinery and oily wastewater generated from flushing of open-air machinery by rainwater, sprinkled water on the road and wastewater generated from flushing of construction materials by rainwater. The wastewater mainly contains petroleum and suspended solids. If it is discharged directly without treatment, it will cause water pollution.
132. Prevention and management measures should be taken for oil leakage from construction machinery. At the construction site, the amount of oily sewage generated by construction is small with an annual production of about 1~2 tons. It is necessary to set up collection barrels to collect oily sewage generated by maintenance of construction machinery. It should be recycled, and its discharge is strictly prohibited. 133. Since the materials, oil etc. required for subgrade construction will be piled at construction site, if they are not managed strictly and covered tightly, they may be washed into the nearby water bodies during the rainy season or rainstorm period. If there is no sheltering, covering and other measures at the powder materials stockyard, the powder materials will also enter into water bodies with the floating dust and cause pollution. If the height of the material stacking place is lower than the water level of each ditch during the flood season, the materials may be submerged by the ditch water, or enter into the water body, rainstorm washing, resulting in pollution of rivers and ditches. Residual substances in waste building materials stockyards can also cause water pollution as the surface runoff enters the water body.
134. Storage facilities for fuels, oil, and other hazardous materials are within secured areas on impermeable surfaces with 110% volume of the materials stored, and provided with bunds and cleanup kits.
2 Domestic sewage 135. The domestic sewage generated during comes from the catering and toilet sewage of the construction workers. There are about 50 construction workers, and the construction period is about 24 months. The domestic water consumption is 50L/person day, and the pollutant production coefficient is 80%. Therefore, the amount of domestic sewage generated is about 3 3 2m /d, 600m /a. The main pollutants in the domestic sewage are COD, NH 3-N, SS and animal and vegetable oils. The concentrations are generally COD: 300mg/L, NH 3-N: 25mg/L, SS: 200mg/L, animal and vegetable oils: 25mg/L.
136. The daily discharge volume of domestic sewage from construction waters is 2m 3/d, the construction personnel rent the private houses, and the domestic sewage is treated through the dry toilets and used for fertilization of the surrounding farmland. It is strictly forbidden that the fecal sewage directly enters the surface water bodies such as river channels along the road. 4.2.2.2 Surface water impact during operation
137. The impact on the water body during operation mainly comes from road runoff. The road surface runoff pollutants mainly come from vehicle exhaust gas, vehicle part wear and tear, road surface wear and tear, transport spillage and atmospheric dust fall. The pollutants in the exhaust
- 57 -
gas of various types of vehicles are deposited on the road surface, the particles worn off from the automobile tires, the earth adhered on the chassis, the pollutants dropping off during braking, and oil leaking when vehicles are in poor working conditions, which will enter into the drainage system of the road with the road runoff generated by the rainfall and eventually enter into the surface water body. The main pollutants are petroleum, organic substances and suspended solids. Generally, the concentration of suspended solids and oil in rainwater is relatively high within 30 minutes from the initial stage of rainfall to the formation of runoff. After half an hour, the concentration decreases rapidly with the extension of rainfall duration. After 40~60 minutes of rainfall, the road surface is basically cleaned thoroughly, and the concentration of road runoff pollutants is relatively stable at a low level. In the actual drainage process, the concentration of pollutants in the road surface runoff when the pollutants reaches the water body has been greatly reduced due to dilution by precipitation, adsorption of pollutants by silt, silt sedimentation and other effects when the road surface runoff is naturally drained into the drainage ditch or side ditch through the cross slope of the road surface, or centrally drained into the drainage ditch through the side slope torrent gutter. Therefore, road runoff has less impact on the water environment during the operation.
4.2.3 Atmospheric environment impact
138. Air pollutants during construction are mainly from demolition, stockyards and construction vehicles, and the asphalt smoke generated during asphalt paving, etc.
4.2.3.1 Increase in dust pollution 139. Increase in dust pollution mainly occurs in the pre-construction demolition and filling process, which is mainly the raise dust caused by construction vehicle transportation and the raise dust in the construction area. (1) Increase in dust of road construction 140. Increase in dust during road construction is mainly caused by the transportation of construction materials, especially the transportation of powdery materials. There are many influencing factors, mainly related to vehicle speed, wind speed, dust deposit volume and dust humidity on the road area, of which, wind speed also directly affects the transport distance of the dust. Stone materials, sand materials and cement will all be transported by trucks, mainly through the existing roads. The amount of road dust deposit in a road section is related to humidity, speed of construction machinery and transport vehicle, wind speed, etc. Wind speed and wind direction also directly affect the pollution range of road dust.
141. In addition, if the road construction materials, especially the powdery materials, are not covered properly, they will also produce dust with the wind during transportation, which will affect the residents on both sides of the road, especially in windy weather, the impact will be more serious. (2) Dust from the stockyard
- 58 -
142. During construction, the materials stockyard is generally set up at construction site. The type and properties of the materials at the stockyard and wind speed have a great influence on the amount of dust generated. Materials with small specific gravity easily generate dust when they are disturbed, and the amount of dust generated is also large accordingly when the proportion of fine particles in the material is large. Dust from the stockyard includes dust from the stockpile blown by wind, loading and unloading and the secondary dust from the dust deposited on the road surface caused by vehicles. This will generate a heavier dust pollution and have a certain impact on the surrounding environment. The dust can be effectively suppressed by timely sprinkling, which can be reduced by 70% (according to the monitoring results of dust reduction test by water sprinkling during construction of G3 expressway). In addition, some wind-proof measures such as covering can be taken to effectively reduce dust pollution for some powdery materials. 143. In order to reduce the impact of dust pollution from stockyard on sensitive receptors, by referring to the location setting of the material stockyards for highways, the construction materials stockyard of the component should be located away from the sensitive receptors. (3) Dust generated by demolition 144. According to the analogy analysis, the daily average concentration of TSP in the demolition process is about 2.7mg/m 3, and the impact range is about 150m around the construction site. The demolition amount of the component is relatively small, about 15,575m 2. The demolition process is a short-term behavior. As long as the demolition work is carried out under the conditions of no wind or small wind, that the demolition waste is timely cleaned up, and enclosure and water sprinkling measures will be taken, and transport vehicles will be covered with the tarpaulin, dust emissions will be reduced by 50%. In this case, the adverse impact of the demolition on the sensitive receptors can be minimized.
(4) Dust from construction site
145. The intensity of dust generated by construction is related to many factors such as construction site conditions, construction methods, construction equipment and construction season, meteorological conditions and soil quality in the construction area, whereas taking appropriate mitigation measures is an important way to control dust pollution. Due to numerous influencing factors, it is difficult to determine the intensity of the dust. In assessment, the analogy method was used to analyze the impact of dust generated during construction based on the monitoring data. The results of site monitoring of dust generation compared with multiple construction sites are shown in Table 4.2-2.
- 59 -
Table 4.2-2 Monitoring results of dust pollution in construction site
TSP concentration (μg/m 3)
Downwind distance of the site Fencing Upwind 20m 50m 100m 150m 200m reference point

Metal baffle 940 510 282 275 258 Constru ction s ite Encircling 270 color strip 1104 535 289 278 264 cloth
146. It can be seen from Table 4.2-1 that with non-enclosed construction, TSP concentration is 354~1540ug/Nm 3 within the range of 20~150m downwind of the site, which is 1.37~5.95 times of the reference point; when the downwind distance is more than 200m, the TSP concentration is 265ug/Nm 3, which is close to the reference point; with metal fences, TSP concentration is 510~940ug/Nm 3 when the downwind distance is 20~50m, which is 1.89~3.48 times of the reference point; when the downwind distance is 100~200m, TSP concentration is 289~258ug/Nm 3, which is close to the reference point. The TSP concentrations beyond the range of downwind 200m all meet the limits for fugitive emission in Table 2 of the “Integrated Emission Standard of Air Pollutants” (GB16297-1996). Therefore, in general, after taking the measures such as timely water sprinkling, reasonable arrangement of construction time and setting up enclosures, the component may have some noise impact on the sensitive receptors close to the construction site. 4.2.3.2 Asphalt smoke pollution
147. Asphalt mixing building will not be set up at the component site. The asphalt concrete will be purchased from outside, so there is no asphalt smoke produced by asphalt melting and mixing operations. However, the impact of asphalt smoke still exists during road paving. By analog with the monitoring data of the impact on the surrounding environment during the asphalt paving of the same type of road, the impact of the asphalt paving on atmospheric environment is slight, thus it will have a very little impact on the sensitive receptors.
4.2.3.3 Impact on air quality during operation 148. The airborne pollutants generated during operation are mainly NOx from automobile exhaust gas. Analogy analysis method is used to analyze the impact of NO 2 on air quality.
- 60 -
149. According to the data of the monitoring report of the existing road and the forecast of traffic flow in the feasibility study report of the component, analogy method is used to assess the impact on air quality during operation. The average daily concentration of NO 2 within the range of 200m of the component will be 0.0418mg/m 3 (the existing daily average monitoring value of 3 NO 2 is 0.022mg/m ), which meets the requirements of Class II standard of “Ambient Air Quality Standard”. In addition, with China’s emphasis on environmental protection, advances in science and technology, and the extensive use of clean energy, the pollutant emission of a single motor vehicle in the future may be greatly reduced. The current ambient air quality along the road of the component is good and the atmospheric environment carrying capacity is large. Vehicle exhaust gas has less impact on air quality along the road. 4.2.4 Noise impact
4.2.4.1 Noise impact during construction 150. The main noise source during construction is mainly from construction machinery and the radiation noise of vehicles. The noise impact is temporary, but due to long construction period, if no measures are taken, the construction will cause significant noise impact on the nearby villages. The road construction process is mainly divided into three stages, namely foundation construction, road surface construction, and traffic engineering construction. The main construction techniques and construction machinery for these three phases are introduced below. 1. Foundation construction: This will take the longest time, use the most machinery and the noise level will be the strongest. It mainly includes foundation treatment, subgrade leveling, earthwork excavation and filling and layered compaction. The construction machinery used are mainly excavators, bulldozers, road rollers, graders, etc. 2. Pavement construction: This will be carried out after the completion of the subgrade construction, which is mainly to spread asphalt concrete. The construction machinery used are mainly large asphalt pavers. According to the domestic noise monitoring during road construction, the road construction noise at this stage is small compared to the subgrade construction.
3. Traffic engineering construction: This mainly involves installation of the road traffic communication facilities and improvement and finalization of the marking lines. The procedure basically does not require large construction machinery, so the noise impact is smaller.
151. The above construction activities are all accompanied by traffic noise caused by transportation of building materials. When building materials are transported, some existing roads will be used near the sensitive receptors. The radiation noise emitted by these transportation vehicles will have certain impact on the sensitive receptors along the line. 152. Based on the analysis above, the noise source distribution of the component is as follows: 1. Road construction machinery such as road rollers, bulldozers, graders, etc. are mainly
- 61 -
distributed in the road area
2. Loaders are mainly concentrated in the culvert area 3. Excavators and loaders are mainly concentrated in the borrow area
4. The transport vehicles mainly run on the access roads between the borrow area and the component site, the access roads set up along the component alignment, and the existing roads connecting the construction site
(1) Prediction and analysis of noise impact during period 153. The construction period will be 24 months. Some high-noise construction machinery will be used during construction, which will have certain impact on sensitive receptors nearby.
1. Construction noise source 154. The noise during road construction mainly comes from construction machinery and transportation vehicles. 155. According to the noise source intensity of common construction machinery and the characteristics of the component in Annex A.2 of the “Technical Guidelines for Environmental Noise and Vibration Control Engineering” (HJ 2034-2013), the intensity analysis of noise sources of the component is shown in Table 4.2-3.
Table 4.2-3 Noise level of main construction equipment Unit: dB(A)

156. Noise generated from road construction has the following characteristics:
- 62 -
1) The construction noise source is different from the general fixed noise source. There are both fixed noise sources and mobile noise sources. Construction machinery is often exposed outdoors, and they will move within a small range for a certain period. However, construction noise pollution is still within the local range compared with the mobile source. 2) Construction equipment is relatively small compared to the range of its influence. Therefore, the construction equipment noise can basically be regarded as the point source.
2. Prediction model of noise impact during construction 157. The following model is adopted for calculations for noise level from construction machinery:
Where: LP — A-weighted noise level dB (A) at a distance of r from the noise source
LP 0 — A-weighted noise level dB (A) at a distance of r0 from the noise source 158. The synthesized noise level generated by each noise source at the prediction point uses the following calculation model:
3. Analysis of noise impact of single construction machinery operation 159. The noise prediction results of different construction machinery at different distances are shown in Table 4.2-4. The noise of a single construction machine can meet the corresponding standard in the “Emission standard of environment noise at boundary of construction site” (GB12523-2011) at a distance of 110m from the construction site, and can reach the standard limits at a distance of 630m at night. However, at construction site, it is usual that a variety of construction machinery work together. Therefore, the noise at the construction site is the result of combined noise of various construction machinery and the noise of various vehicles entering and leaving the construction site. The distance of noise meets the standard limit is much more than 110m during day time and 630m during night time.

4. Analysis of noise impact of simultaneous operation of construction machinery
160. The subgrade of the component is 57m wide. The construction machinery operates in mobile way and are considered as a point source located at the centerline of the road, and the minimum distance from the road boundary is about 28.5m. Construction time is considered as the continuous operation at the same load during day and night. According to the characteristics of different construction stages, the noise impact at different construction stages at the construction site boundary is predicted by assuming that the construction machinery work at the same time, see Table 4.2-5. 161. According to the prediction results, in the case of multiple machinery working together at different construction stages, the max. noise at the boundary of road construction site
- 64 -
in day time exceeds the “Emission standard of environment noise for boundary of construction site” (GB12523-2011) by 11.7dB(A), and the maximum noise in night time exceeds the standard limit by 26.5dB (A). During construction, low-noise equipment will be selected, the construction position will be reasonably arranged, and the sound-absorbing enclosure of 2.5m height will be installed at the construction site boundary. The enclosure can serve as a sound barrier to reduce the noise impact. Therefore, the construction noise impact of the component is mainly concentrated at night, and the construction at night has a significant impact on the acoustic environment at the site boundary. Mitigation measures for noise impact at night should be taken around the construction area.

5. Analysis of noise impact at sensitive receptors during construction period
162. The nearest sensitive receptor of the component is 33.5m away from the road centerline. According to the construction stage and construction machine operations described in Table 4.2-3, the predicted noise levels at the closest sensitive receptors at different construction stages are shown in Table 4.2-6. Table 4.2-6 Combined noise values produced by various construction machinery at the closest sensitive receptor Unit: dB(A)
Closest sensitive receptor Subgrade work Pavement work
33.5 m from the centerline of the road 80.3 80.1
163. According to Table 4.2-6, when the construction machinery is working at the same time,
- 65 -
the construction noise has a great impact on the sensitive receptors. According to the Class II standard of the “Acoustic Environmental Quality Standard” (GB3096-2008), the maximum value at the sensitive receptor exceeds the standard by 20.3dB(A) in daytime, and at night time by 30.3dB(A). Since most of the residents at the sensitive receptors work on the land or work outside during daytime, the construction noise impact during day time is smaller than that at nighttime. The nighttime construction produces a significant impact on the acoustic environment quality at the sensitive receptors. After low-noise equipment is used and solid enclosure is installed, the impact can be reduced. Therefore, during the construction, measures including prohibiting construction at nighttime (22:00-6:00) should be taken. If it is difficult to avoid night construction, approval has to be obtained from relevant department and the local residents should be informed prior to construction. 164. With the completion of the construction, the impact of construction noise will also end. The environmental impact of construction noise is acceptable when construction enclosures and no-night construction measures are taken. 4.2.4.2 Traffic noise impact during operation 165. The noise impact during operating mainly comes from traffic noise. There are residents living along the road alignment. Therefore, it is necessary to predict and assess the overall noise level in the near, medium and long term after the project is completed and is open to traffic, and the noise impact on the sensitive receptors in the surrounding assessment range, so as to develop reasonable noise reduction measures according to the actual situation of noise impact and local conditions, and provide a scientific basis for future related planning within the project area.
(1) Strong noise source 166. According to the feasibility study report, the prediction results of traffic volume in each prediction year after the completion of the completion (near term 2021, mid-term 2027, and long- term 2035) are shown in Table 4.2-7.

Note: Small vehicles include small passenger cars and pickup trucks; medium-sized vehicles include medium-sized trucks; and large-sized vehicles include buses, large trucks, and trailers. 167. According to Annex A.2.1.1 classification method in “Technical Guidelines for Environmental Impact Assessment — Acoustic Environment” (HJ2.4-2009), small-sized vehicles include small passenger cars and pickup trucks, medium-sized vehicles include medium-sized trucks, and large vehicles include buses, large trucks and trailers. The hourly traffic volume of the component during daytime and nighttime is calculated according to 4:1. The hourly traffic volume for each prediction year and each vehicle type during daytime and night time is shown in Table 4.2-9.

168. Noise during operation mainly comes from the traffic noise generated by the motor vehicles. After the road is put into operation, the noise source of the motor vehicles running on the road is an unsteady source. When the vehicle is running, its engine, cooling system and transmission system, etc. will generate noise; the airflow turbulence caused by driving, the exhaust system and the friction between the tires and the road surface also generate noise. 1. Calculation formula 1) Radiated noise level
- 67 -
169. The average radiated noise level of the “i” type of vehicle at the reference point (7.5m) is calculated by referring to the highway traffic noise prediction model recommended by the “Specification for Assessment of Environmental Impact of Highway Construction Projects” (JTG B03-2006):
Small vehicle: LW,s ＝12.6+34.73lgVs

- 71 -
the prediction point around the viaduct is affected by multiple lanes on the bridge and under the bridge, and the prediction point of the high-rise building on the roadside is affected by multiple lanes on the ground), the sound level of each lane to this prediction point should be calculated respectively, and the contribution value is obtained by superimposition of them. 3. Calculation of correction amount and attenuation amount
A. Calculation of correction amount (ΔL1) 1) Longitudinal slope correction Calculation formula:
The correction factor of the highway longitudinal slope ΔLslope can be calculated as follows:
Large vehicle: ΔLslope = 98× β dB(A)
Medium vehicle: ΔLslope = 73× β dB(A)
Small vehicle: ΔLslope = 50× β dB(A) Where: β — the slope of the highway longitudinal slope, %.
Parameter correction involving sensitive receptors: 174. According to the design and the current status, the longitudinal slope of road section at each sensitive receptor is small, and the impact of the longitudinal slope can be considered negligible.
2) Pavement correction
The value of intensity correction amount △Lpavement of traffic noise source caused by road pavement is shown in Table 4.2-14.

- 72 -
175. Where: “a” is a function of temperature, humidity and acoustic wave frequency. In the prediction calculation, the corresponding air absorption coefficient is generally selected according to the perennial average temperature and humidity of the area where the project is located (Table 4.2-15).

The ground type can be divided into: i. solid ground, including paved road surface, water surface, ice surface and tamped ground; ii. loose ground, including ground covered by grass or other plants, and ground suitable for plant growth, such as farmland; mixed ground, composed of solid ground and loose ground.
177. When the sound wave propagates across loose ground, or mixed ground, most of which is loose ground, the octave band attenuation caused by the ground effect can be calculated by the formula under the premise that only the A-weighted sound level is calculated at the prediction point.

Where:
r — distance from the sound noise to the prediction point, m;
hm— average height of the propagation path from the ground, m; can be calculated 2 according to Fig. 4.2-2, hm = F/r ; F: area, m ; r, m;
If Agr is a negative value after calculation, Agr can be replaced with “0”.

3) Attenuation amount of obstacle ( Abar )
178. The attenuation Abar of the sound shadow area on both sides of the high embankment or low roadcut is the additional attenuation caused by the prediction point.
179. When the prediction point is in the sound irradiation area, Abar =0
180. When the prediction point is in the sound shadow area, Abar is determined by the sound path difference δ.
Calculation of δ is shown in Fig. 4.2-2, δ=a+b-c, Abar in Fig. 4.2-3.

In the range of the sound shadow zone of the first-row houses along the road, the value can be taken in the approximate calculation according to Fig. 4.2-5 and Table 4.2-16.

The attenuation caused by dense leaves with a total length of 10m to 20m is given in the first row in Table 4.2-17. The attenuation coefficient when passing through dense leaves with a total length of 20m to 200m is given in second row. When the length of path passing through the dense leaves is greater than 200 m, the attenuation value for 200 m can be used.

6) Calculation models related to Amisc attenuation term.
185. Other attenuations of Amisc include the attenuation when passing through industrial sites, and attenuation when passing through housing groups, etc. In the acoustic environmental impact assessment, generally, additional corrections caused by changes in natural conditions (e.g., wind, temperature gradient, fog) are not taken into account.
C. Correction amount (ΔL3) caused by reflection, etc. 1) Correction amount of noise (impact) at intersections of urban roads
The noise correction values (additional values) at the intersections are shown in Table 4.2- 18. Table 4.2-18 Additional value of noise at intersection

When the spacing between buildings on both sides of the line is less than 30% of the total calculated height, the amount of reflected sound correction is: When the buildings on both sides are reflective surfaces: When the buildings on both sides are general absorption surfaces: When the buildings on both sides are fully absorption surfaces: Where: w — spacing of the reflective surfaces of the buildings on both sides of the line, m Hb — average height of the structures, h, which is calculated by taking the average height of the lower side of the two sides of the line and substituting it into the formula, m. (3) Prediction results of traffic noise impacts at different distances along the road during operation 187. Based the prediction models and in combination with various parameters determined by the engineering design, the predicted value of traffic noise along the line is calculated with a range of 40~200 m from the centerline on both sides of the road. 188. As the road surface elevation changes constantly, the ground forms on both sides of the road also change constantly. Therefore, the traffic noise under the condition of flat subgrade and open area (without considering obstruction of obstacles) is predicted for 2021, 2027 and 2035, respectively. The prediction results are shown in Table 4.2-19. - 78 - Table 4.2-19 Traffic noise levels during operation Unit: dB(A) Distance to centerline of the road (m) Time Year interval 40 50 60 70 80 100 120 140 160 180 200 Day time 61.8 60.5 59.4 58.6 57.9 56.7 55.8 55.0 54.3 53.7 53.2 2021 Nighttime 55.7 54.3 53.3 52.4 51.7 50.6 49.6 48.8 48.1 47.5 47.0 Day time 62.7 61.3 60.3 59.4 58.7 57.5 56.6 55.8 55.1 54.5 54.0 2027 Nighttime 56.5 55.1 54.1 53.2 52.5 51.4 50.4 49.6 49.0 48.4 47.8 Day time 63.2 61.8 60.8 59.9 59.2 58.1 57.1 56.3 55.7 55.1 54.5 2035 Nighttime 57.0 55.7 54.6 53.8 53.1 51.9 51.0 50.2 49.5 48.9 48.4 189. Near term (2021): the noise level at the boundary line of the road will meet Class IV A standard, and the noise level beyond 54m from the centerline will meet Class II standard in day time; the noise level beyond 45m from the centerline will meet Class IV A standard, and the noise level beyond 111m from the centerline will meet the standard Class II in night time. 190. Mid-term (2027): the noise level within the boundary line of the road will meet Class IV A standard, and the noise level beyond 63m from the centerline will meet Class II standard in day time; the noise level beyond 51m from the centerline will meet Class IV A standard, and the noise level beyond 130m from the centerline will meet Class II standard in night time. 191. Long term (2035): the noise level within the boundary line of the road will meet Class IV A standard, and the noise level beyond 69m from the centerline will meet class II standard in day time; the noise level beyond 56m from the centerline will meet Class IV A standard, and the noise beyond 146m from the centerline will meet Class II standard in night time. (4) Prediction results of noise level at sensitive receptors along the line 1) Background noise value at sensitive receptors 192. The so-called background noise in assessment refers to the noise other than the traffic noise of the proposed road, including the superimposed effects of other various noise sources such as social life noise. 193. According to the site investigation, the existing noise sources at the 12 sensitive receptors are mainly from the existing road. Therefore, L 90 was recorded while the continuous equivalent A-weighted sound level was recorded during monitoring. The L 90 value in the acoustic environment quality monitoring results at each sensitive receptor was used to reflect the - 79 - background noise in this assessment. 194. Noise monitoring was conducted twice in day time and night time, respectively. The larger value of L 90 is taken as the background value. If the sensitive receptors of the same road section have similar characteristics and similar background environment, their background values use the monitored value of the monitoring points arranged for the same road section. The background noise levels at the sensitive receptors are shown in Table 4.2-20. Table 4.2-20 Background noise levels at sensitive receptors Background value Analogous sensitive dB(A) SN Name of sensitive receptor receptor Day Nighttime time 2nd storey at Xiaoshang (Class 2nd storey at Lingwei 48.1 42.9 IV A area) (Class IV A area) N1 2nd storey at Xiaoshang (Class 2nd storey at Lingwei 45.8 41.4 II area) (Class II area) 2nd storey at 2nd storey at Lingwan (Class IV Xiaotancun (Class IV 47.5 43.2 A area) A area) N2 2nd storey at 2nd storey at Lingwan (Class II Xiaotancun (Class II 45.5 41.9 area) area) 2nd storey at Xiaozheng (Class 2nd storey at Xiaodian N3 44.3 41.1 II area) (Class II area) Ground storey at Zaoying 45.5 42.4 Lvcheng (Class IV A area) 3rd storey at Zaoying Lvcheng 46.9 43.4 (Class IV A area) 6th storey at Zaoying Lvcheng 46.5 42.9 (Class IV A area) 10 th storey at Zaoying Lvcheng N4 45.3 42.6 (Class IV A area) Ground storey at Zaoying 44.4 41.8 Lvcheng (Class II area) 3rd storey at Zaoying Lvcheng 45.3 42.6 (Class II area) 6th storey at Zaoying Lvcheng 45.5 42.1 (Class II area) 2nd storey at Xiaoli (Class II 2nd storey at Luoyecun N5 44.5 41.6 area) (Class II area) - 80 - Background value Analogous sensitive dB(A) SN Name of sensitive receptor receptor Day Nighttime time 2nd storey at Wangye (Class II N6 45.1 42.2 area) Ground storey of Bo’ai Hospital 46.7 42.4 (Class II area) N7 3rd storey of Bo’ai Hospital 47.3 42.8 (Class II area) 2nd storey at Huangcun (Class II N8 46.8 42 area) 2nd storey at Jiajia (Class IV A 47.7 42.6 area) N9 2nd storey at Jiajia (Class II 45.4 41.4 area) 2nd storey at Xiushi Quarter 48.9 42.8 (Class IV A area) N10 2nd storey at Xiushi Quarter 47.4 42.5 (Class II area) 195. The predicted noise levels at the sensitive receptors is formed by superimposing the predicted value of the traffic noise with the background noise levels by considering the acoustic environment influencing factors and making appropriate correction. When correcting the traffic noise value, factors such as the terrain at the sensitive receptors, the height difference to the road surface, and the greening vegetation should be comprehensively considered. As the houses along the line are multi-storey, according to the characteristics of the road and conditions of the sensitive receptors, the most serious cases of the noise impacts of the proposed component on the sensitive receptors are predicted. The prediction results are shown in Table 4.2-21. 196. There are total 12 sensitive receptors along the alignment, including 11 residential areas and 1 hospital. Based on Table 4.2-21, the specific assessment of noise levels during operation is as follows. 197. There are 6 residential areas involving Class IV A area. By mid-term of the operation, noise levels will range from 62.1~65.8dB(A). No sensitive receptors exceed the standard during the day time. Noise levels during nighttime will be 56~59.6dB(A). 6 sensitive receptors exceed standard by 1~4.6 dB(A). 198. There are 11 residential areas involving Class II area. By mid-term of the operation, the range of predicted noise levels during day time is 55.4~60 dB(A). There is no sensitive receptor exceeding the standard during the day time. Predicted noise level during night time is - 81 - 49.6~54.4dB(A), and there are 9 sensitive receptors where noise levels exceed the standard by 0.1~4.4 dB(A). 199. By mid-term of the operation, the predicted value of Bo’ai Hospital during day time is 63.7 dB(A), and the over-standard value reaches 3.7 dB(A).

Solid waste during construction mainly includes the spoiled soil produced by excavation, domestic garbage and waste generated by demolition of buildings. a. Domestic garbage 202. Construction domestic garbage will be collected by the environmental sanitation department and transported to Wuhu Lüzhou Environmental Protection Energy Co., Ltd for disposal. b. Spoiled soil generated by excavation 203. The spoiled soil includes the topsoil at the main component area and the topsoil and sludge at the construction site. 204. The topsoil of the main component area will be piled up in the temporary topsoil stockyard set up in the main component area, and will be used for soil covering for greening in the later stage. The topsoil at the construction site area will be piled up in the temporary topsoil stockyard set up at the construction site, and will be used for the soil covering for re-cultivation of borrow pits in the later stage. Sludge cannot be used for subgrade filling, but part of it can be used as the bottom soil of the green belt, and part of it can be transported to the borrowing site for land remediation. Therefore, the spoiled soil will not cause negative impact on the surrounding environment. c. Construction waste produced by demolition 205. Construction waste includes the remaining construction materials, including lime, prefabricated components, asphalt concrete, etc., which shall be recycled as much as possible. For those that cannot be recycled, it shall be transported to urban construction garbage dump for treatment following the PRC regulations. Construction waste has small impact on the environment. 206. Therefore, solid waste produced during the construction will not have a significant impact on the surrounding environment. 4.3 Pollution prevention and control and ecological protection measures 4.3.1 Ecological protection measures 4.3.1.1 Animal and plant protection measures 207. Vegetation protection (1) For artificial plantations affected by the component construction, they should be transplanted as much as possible before construction, and it is strictly prohibited to destroy them. (2) Strengthen construction management, and strictly prohibit construction workers and construction machinery from destroying local vegetation. - 92 - (3) Select native species, plant them immediately after the completion of the earthwork, and provide necessary maintenance at the beginning of planting. If the three-dimensional green slope protection engineering is adopted, pioneer species with strong fixation can be selected first, which shall be gradually replaced with the local species during the operation. (4) Land for temporary use shall be restored in time according to local actual conditions and residents’ requirements, and ecological restoration shall be completed before completion and acceptance of the component. 208. Wildlife protection 209. Through site investigation, there is almost no big wild animals along the alignment. There are small wildlife moving around in some areas such as birds and rodents, and there are no national key protected wild animals. The assessment recommends to protect the animals in accordance with the following requirements during construction. (1) Place a billboard before commencement of construction: before construction workers enter the construction site, place temporary billboards at the construction site and surrounding areas, and succinctly introduce relevant laws and regulations regarding nature conservation. (2) Reduce environmental disturbances and protect wildlife 210. Use special device for road lamps during construction to prevent the light from being emitted outside construction site to reduce the interference to wild animals. If protected animals are encountered during construction, it is strictly forbidden to harm them. If wild animals are accidentally injured, immediately contact the local wildlife protection department and have professionals to handle the issue. 4.3.1.2 Temporarily occupied land restoration measures 211. Temporarily used land, as the construction site, borrow and spoil areas occupied during construction, shall be restored by the peeled topsoil. It is recommended to plant alfalfa, white clover, etc. after land leveling and soil loosening on the restored land which shall be restored to grassland first, and then restored to cultivated land after 2~3 years. 4.3.2 Water pollution prevention and control measures 212. During construction, set up sedimentation tank at the construction site for preliminary treatment of wastewater. The solid waste generated from the sedimentation tank will be treated together with the construction waste. The place for stacking and dumping building materials (including abandoned building materials), residue and domestic garbage must be approved by the local environmental protection department. It is strictly forbidden to pile up and litter casually. Domestic sewage will be returned to the field after being treated by the dry toilet, and it is forbidden to directly discharge domestic sewage into surface water body. - 93 - 4.3.3 Air pollution prevention and control measures 213. (1) Dust 1) During construction, the contractors shall set up the site layout plan, project overview board, safety production board, fire protection and guard board, civilized construction board, environmental protection board, board for name list of management staff and supervision phone number, etc. according to the provisions of the “Regulations for Construction Management of Construction Site”. When demolishing houses or other buildings (structures), fences shall be set up, and water sprinkling measures should be taken to suppress the generation of dust. 2) Earthwork excavation or filling and transfer, etc. shall not be carried out when forecast wind will reach scale 4 or above. 3) If construction waste cannot be cleared and transported out completely within 48 hours, a temporary stockyard should be set up at the construction site, which should have dust-proof measures such as use of enclosure and covering with dust-proof net. Stockyard for sand should have regular water sprinkling measures and cover with tarpaulins. Materials such as lime which cannot be sprinkled with water should be stored in a stockyard with three sides closed and rainproof roof provided above the stockyard. 4) For the land at the construction site unused for more than 3 months, the constructors shall temporarily green or pave the bare land. 5) During construction, a vehicle washing platform shall be installed at the entrance of the construction site for cleaning of the transportation vehicles. Before the vehicle leaves the construction site, the tires and vehicles shall be cleaned on the vehicle washing platform, the vehicles are not allowed to run on road with mud on them. Vehicle washing platform should be provided with overflow prevention pedestal, waste water diversion channel, wastewater collection tanks, sedimentation tank and other control facilities to collect waste water and mud generated during vehicle washing, construction and water level reduction. The sticky soil from the transportation vehicles on the paved road at the exit of the construction site shall not exceed 10m, and shall be cleaned and washed in time. 6) Transportation vehicles for materials, soil and garbage entering and leaving the site should use closed hopper as far as possible, and ensure that no materials are spilled. If there is no closed hopper, the loading height of materials, garbage and muck should not exceed the upper edge of the vehicle trough, and the hopper should be covered with tarpaulin. At least 15cm below the upper edge of the groove should be covered with tarpaulin to ensure that the material, muck, garbage, etc. are not exposed. Vehicles should transport materials, muck and garbage according to the approved route and time. 7) The dust deposited on the roads at the construction site shall be cleaned by water spraying. It is not allowed to clean the roads directly without the dust suppression measures such as water sprinkling. - 94 - 8) During the construction, for the ground exposed on the construction site, when the weather is fine, the water should be sprinkled on the ground 2~7 times a week, depending on the situation. When dust is heavy, the frequency of water sprinkling should be increased. 9) The range of the contractors’ cleaning responsibility area should be determined according to the influence of construction dust, and is generally set within the range of 20m around the construction site. 10) Install the GPS positioning system for the muck transport vehicles, strictly implement the closed transportation, and implement the washing and cleaning measures. 11) It is forbidden to burn asphalt, linoleum, rubber, plastic, leather, garbage and other substances that produce toxic and harmful smoke and malodorous gases at the construction site. 214. Asphalt smoke The paving of asphalt pavement should be carried out in favorable weather condition to facilitate rapid dissipation of asphalt smoke and minimize its pollution to the atmospheric environment. 4.3.4 Noise pollution prevention and control measures 4.3.4.1 Noise prevention and control measures during construction 215. Use low-noise mechanical equipment, maintain and repair the equipment often to avoid noise increase due to deteriorated equipment performance. 216. Reasonably select transportation route and transport as far as possible during day time when using existing roads for transporting construction materials to reduce the impact on the residents along road at night. In addition, when vehicles pass through villages/towns, they should slow down and honking is prohibited. Since the transportation route cannot be determined at present, it is recommended that the IA should require the contractors to provide the route. The IA should carry out supervision according to the finalized transportation route, and strengthen the supervision together with the local environmental protection department if needed. 217. Compared with the operation period, noise impact during construction is short-term and temporary. Based on the assessment, noise emission of the construction machinery does not meet the limits set in the “Emission standard of environment noise for boundary of construction site” (GB12523-2011), and Class II standards set in the “Acoustic Environmental Quality Standard” (GB3096-2008). Therefore, high-noise machinery should stop operation near sensitive receptors during nighttime (22:00-6:00). If it is unavoidable, relevant approval must be obtained and the public should be informed prior to construction. During daytime, proper noise reduction measures shall be taken, for example, installing 2.5m high solid enclosure, etc. to ensure that of the noise levels will meet the “Emission standards of environment noise for boundary of construction site” (GB12523-2011). 218. For the sensitive receptors close to the construction site , construction shall not be conducted at nighttime, and construction monitoring should be strengthened as well during the construction. If the noise levels at the sensitive receptors do not meet corresponding standards, - 95 - temporary noise reduction measures, such as setting temporary sound insulation barrier, shall be taken. 219. During construction, the “Emission standards of environment noise for boundary of construction site” (GB12523-2011) should be strictly implemented. 220. Strengthen the noise monitoring during the construction period and take effective measures to prevent and control noise pollution in a timely manner. 4.3.4.2 Noise prevention and control measures during operation 221. Measures to mitigate the impacts of noise 222. Traffic management measures 1. By strengthening traffic management, including erecting signs for speed limit and no honking near sensitive receptors, etc., the traffic noise pollution can be effectively controlled. 2. Strengthen the management of roads, and often maintain the road surface to avoid traffic noise caused by bumps due to poor road conditions. 223. Planning control recommendations 224. When planning the villages and towns along the line, pay attention to the following aspects: 225. According to the prediction of the traffic noise in the mid-term of the component, , it is recommended that no new schools, hospitals, nursing homes, residential buildings shall be built close to the road. But since there are densely distributed buildings close to the road, commercial buildings , warehouses, factories, etc., with the height not lower than these buildings can be planned in the future. 226. When planning and constructing residential areas along the line, it is recommended to optimize the house layout design with kitchen, corridor, bathroom, living room close to the road site and bedroom on the side away from the road. 227. Due to the multi-factor influence in software simulation calculation, the degree of impact of actual noise may be different from the prediction. The IA shall engage a licensed environmental monitoring company to regularly carry out noise monitoring at sensitive receptors. 228. Noise prevention measures at the sensitive receptors 229. In combination with the actual situation and in line with the principle of due consideration to fairness, the assessment intends to take effective and practical noise reduction measures at the sensitive receptors where noise exceeds the standards in near-term and mid-term of operation, so that the acoustic environment (outdoor or indoor) at the sensitive receptors can meet the standards. Considering the predicted traffic flow is only for reference due to modeling constraints, noise monitoring shall be conducted at the sensitive receptors. In case of non- compliance, additional mitigation measures shall be taken. - 96 - 230. There are 12 acoustic sensitive receptors within the assessment scope. Considering the constraints of noise impact modeling, it is proposed to install sound-insulation window at the sensitive receptors where noise exceeds the standard by over 3dB in the medium term, and reserve fees and monitor the first row of sensitive receptors where noise exceeds the standard by less than 3dB along the alignment. If there are sensitive receptors where noise exceeds the standard, additional measures such as installing sound-insulation windows should be taken, and the increase in the cost will be included in the noise prevention and control costs. 231. The cost of ventilation and sound-insulation window is estimated as CNY 500 per m2, and the window area is generally 2 m2. Each household normally has 5 windows. The cost is estimated at CNY 5,000 per household. 232. The sound-insulation window of 600 m2 (60 households) will be installed at three residential areas, and the sound-insulation window of 40m 2 will be installed in the hospital. Noise monitoring will be conducted at sensitive receptors where predicted noise level exceeds the standard by less than 3 dB in the mid-term. If the monitoring results show non-compliance, sound-insulation windows shall be installed at 5 locations (830m 2 (83 households)) (not including Zaoying Lvcheng). 233. It is proposed to limit the vehicle speed of 60km/h for the road section of Zaoying Lvcheng as prevention and control measures. After speed reduction of vehicles, the noise over- standard value will be lower than 3dB. therefore take tracking and monitoring measures for this road section. If monitoring results indicate non-compliance, 2080 m2 (208 households) insulation windows shall be installed. 234. Sound-insulation windows can generally reduce noise by 25dB. Therefore, according to the prediction results, the indoor acoustic environment of the buildings installed with sound- insulation windows can meet the limits of 55dB (A) during daytime and 45dB (A) during nighttime. 235. Noise reduction measures at sensitive receptors should be implemented completely before operation. 236. The main measures and cost estimates are shown in Table 4.3-1: Table 4.3-1 Main noise prevention and control measures Sensitive point Measures Budget 4 sensitive receptors Ventilation and sound-insulation window (Linwei, Xiaoshang, Bo’ai CNY 320,000 640m 2 Hospital and Huangcun) 5 sensitive receptors Reserve budget for sound insulation window (Linwan, Xiaoli, Wangye, 830 m2 (83 households) in case of non- CNY 465,000 Xiushi Quarter, Jiajia) compliance - 97 - Installation of speed limit sign (60km/h).

The total cost of noise prevention measures for sensitive receptors is estimated to be CNY 1.845 million. Considering the uncertainty of the traffic flow in the medium-term and long- term, additional investment may be required. Therefore, 30% contingency cost will be added. In total, CNY 2,398,500 shall be reserved for implementing noise reduction mitigation measures. 4.3.4.3 Community and workers’ health and safety 238. Contractors will undertake Health and safety risk assessment of construction works and implement relevant construction phase Environment, Health and Safety (EHS) plan in line with construction good practice as set out in EHS Guidelines on Construction and Decommissioning and Occupational Health and Safety guidelines. 239.

The environmental supervision report is the indispensable material for applying for environment protection acceptance on completion of the component. 5.3.5 Supervision work framework (1) Establish and improve a sound organization system for environmental supervision and protection - 117 - 275. Environmental supervision work has a dual nature. In terms of its relative independence, it is necessary to engage a full-time organization and equip full-time staff with qualified professionals. The environmental supervision work should be included in the scope of overall component supervision work. The supervision company should have one full-time environmental protection staff to carry out total quality management according to the dual requirements for component quality and environmental protection quality. The environmental protection work and environmental supervision work will be supervised by local EPBs. (2) Formulate relevant environmental protection management measures and implementation rules 276. Formulate relevant environment protection systems such as “Environmental Protection Management Measures for Construction Areas of Projects” and “Implementation Rules for Environmental Protection Work” on the basis of implementation of national environmental protection policies and regulations, and the EMP. (3) Establish a sound environmental supervision system 277. A work record system, namely, the “supervisory diary”, which describe the inspection findings, environmental issues, analyze the causes of the problems and the responsible units and proposed measures, etc. 278. Reporting system. This is an important channel for internal and external communication and top-down communication and information transmission, including monthly, quarterly and semi-annual monitoring reports. 279. Memo system . Matters to be handled by the contractors and the supervision company shall be exchanged and confirmed through memos. For urgent issues, oral notice can be given first followed by memo. 280. Regular meeting system. An environmental protection meeting shall be held once a month to review and summarize the environmental protection work in the past month. Contractors, the environmental engineer from supervision company, IA’s environment staff shall participate to discuss the implementation of the EMP and any issues to be solved. 5.3.6 Key points of environmental supervision 281. Table 5.3-1 summarizes the environmental supervision requirements. - 118 - Table 5.3-1 Summary of Environmental Supervision SN Supervisi on Key supervision contents location ● Supervise whether the subgrade excavation and filling operations are strictly controlled within the scope of construction work, and whether measures are taken to prevent the waste soil from rolling into the cultivated land; ● Supervise transportation of the subgrade earthwork and rockwork, whether the earthwork and rockwork transportation plan are strictly implemented, and whether there is casual abandoning of waste soil along the line; ● Supervise the handling process of physical and cultural resources; ● Supervise whether nighttime construction is avoided as far as possible as. If it is necessary to carry out construction at night, whether it is approved by the local environmental protection department. ● Supervise the transportation and temporary storage of easily spilling Subgrade bulk materials such as lime at the construction site, and whether 1 pavement windproof covering measures are taken to reduce dust generation; work ● Supervise whether the construction site is sprinkled with water to reduce dust as required; ● Supervise the implementation of temporary soil and water conservation measures; ● Supervise whether sedimentation tanks are temporarily set up on both sides of the subgrade when excavating the subgrade at the concave location of the longitudinal section of the subgrade or the location of rainy ground where there is surface runoff, and there is a river channel or pond near the subgrade; ● Supervise whether the construction workers have the behavior of cutting down or destroying the vegetation and crops outside the construction area and destroying local ecology; ● Check the compliance of noise at the sound sensitive receptors. - 119 - ● Check whether contractors strictly implement the training requirements in the bidding documents; ● Check whether the setting of temporary construction land avoids the basic farmland protection area; ● Check whether the sewage is directly discharged into surface water Temporary bodies, and whether domestic sewage (especially fecal sewage) is collected and treated in septic tanks; land for 2 constructio ● Check whether the stacking of construction materials and the n construction waste on the temporary construction land avoids the inner side of the emban kment along the line and nearby rivers and lakes or the upper limit of the highest water level line; ● Check whether the domestic garbage is dumped at the designated location, whether the selection of the dumping site is reasonable, and whether the domest ic garbage is centrally collected and treated by the sanitation department regularly; ● Check whether the construction site is reasonably arranged, from the concentrated residential area and nearby towns; ● Check whether n ighttime construction is prohibited, and whether construction vehicles are prohibited at night; Villages 3 along the ● When construction vehicles work at night, measures such as alignment slowing down and prohibiting honking should be taken; ● Avoid construction at night as far as possible where there are concentrated sensitive receptors along the line, especiall y, prohibit high-noise construction operations such as prohibiting pile driving, and arrange construction time reasonably. 5.3.7 Supervision cost during construction period 282. Cost estimates for environmental supervision are shown in Table 5.3-2. - 120 - Table 5.3-2 Cost estimates of environmental supervision Item Cost (CNY 10,000) Remarks Service fee 24 10000 Yuan/month × 24 months × 1 person Cost of office 10 Based on 50,000 Yuan/year tentatively facilities Cost of living facilities for 6 Based on 30,000 Yuan/year tentatively supervision staff Cost for training and transportation 10 Based on 50,000 Yuan/year tentatively facilities Total 50 5.4 Training 5.4.1 Staff training during construction 283. The successful implementation of the EMP relies on environmental management knowledge and work experience of the environment management staff. Staff training can be conducted at home and abroad, and location for overseas training will be selected in the countries with mature highway construction and operational management systems. For domestic training, experts from universities, environmental research institutions and professional advisory bodies will be invited to give lectures. 284. The contractors must strengthen the self-inspection of environmental protection. Even if such self-inspection is not the ultimate goal, it can help to establish the awareness of environmental protection, and help the environmental management and supervisory agencies to better carry out supervision. For the contractors to conduct more favorable self-inspection, training shall be provided to the contractors. The specific contents of the staff training plan are shown in Table 5.3-1. Training contents include: (1) Regulations, documents and related requirements of the RRC, ADB, and Anhui Province concerning environmental protection in the construction management. (2) Environmental protection measures proposed in the design and environmental protection requirements during construction. (3) Environmental protection guidelines during construction. - 121 - 5.4.2 Staff training during operation 285. During operation, the training of newly recruited environmental protection full-time and part-time staff should be provided by IA, and relevant environmental protection experts from universities, research institutes and operation management units may be invited to give lectures. These full-time and part-time staff may also participate in short-term training courses. The environmental protection staff training plan is shown in Table 5.4-1.

Environmental management requires the necessary information exchange between different departments and different positions within the organization, and the organization should also report relevant information to the outside (related stakeholders, the public, etc.). 287. Internal information exchange can be conducted in various ways, such as meetings and internal reports; a formal internal meeting must be held per month, and all exchanged information should be recorded and put on file. 288. The external information exchange should be conducted semi-annually or annually, and the information exchange with relevant stakeholders should form minutes of meeting and should - 122 - be put on file. 5.5.2 Recording 289. In order to effectively implement the AMP, the IA must establish a complete recording system and keep the records in the following aspects: (1) Requirements of laws and regulations. (2) Various kinds of license documents. (3) Environmental factors and related environmental impacts. (4) Training activities. (5) Inspection and assessment activities. (6) Monitoring data. (7) Remedial measures. (8) Information of related parties. (9) corrective actions. (10) Audit and review records. 290. In addition, necessary control must be carried out on the above various types of records, including identification, collection, cataloging, archiving, storage, management, maintenance, inquiry, shelf life, disposal, etc. of the records. 5.5.3 Reporting 291. The contractor, monitoring company and IA should record the progress of the component, the implementation of the EMP, and the results of environmental quality monitoring during the component implementation process and report them to the relevant departments in a timely manner. The reporting mainly includes the contents of the following four parts: (1) The monitoring company and the contractor should make a detailed record of the implementation of the EMP and report it to the IA in a timely manner. (2) The progress report prepared by IA (such as monthly report, quarterly report, annual report, etc.) must include the contents of the EMP implementation. (3) EA shall submit environmental monitoring reports semi-annually during construction and annually during operation to ADB. Template for environmental monitoring reports is shown in Appendix I. - 123 - 6 Analysis of Alternatives 292. The existing road is one of the newly added east-west horizontal lines in “National Highway Network Planning (2013~2030)” and is also one of the 12 eastbound trunk highways in “Infrastructure Planning for The Demonstration Area of Wanjiang City Belt to Undertake Industrial Transformation”. With the increasing traffic volume, the current road grade and technical specifications cannot meet the traffic demand, the construction of the component is imperative. In order to avoid occupying the cultivated land, woodland as well as avoid the sensitive area of sound environment, the plan for extension the width of the existing road is proposed. 6.1 Without Project Alternatives 293. If other alignment is selected, the extra land acquisitions especially acquisition for cultivated land will be increased, which may lead to more agricultural production loss. In addition, more lands will be temporarily occupied for road construction, which may lead to more interferences. The alignment of the existing road is straight, which will decrease the length of the road, the land acquisition and occupation as well as environment protection indicators. 294. The existing road is a first-class road. Through extending the width of the existing roads, the new land acquisition and occupation will be reduced, thus reducing the impact on agricultural production. In addition, the existing linearity is in line with regional urban planning and traffic planning, and can better connect with the surrounding road network. Therefore, the option for widening the existing road is selected under the project. - 124 - 7 Public consultation and information disclosure 7.1 PRC and ADB requirements for public participation and information disclosure 1. PRC Requirements 295. Relevant provisions in the PRC Environmental Impact Assessment Law (revised in 2016) and the Regulations on the Administration of Construction Project Environmental Protection (No. 253 Order of the State Council, 1998, revised in 2017) require that an EIA study for a construction project shall solicit opinions from affected residents, as well as other organizations and concerned stakeholders. However, the requirements for public consultation are different for various sectors and projects. For an environmental Category A project a full EIA report is required including two rounds of public consultations, while for a Category B project only a simplified tabular EIA is required without the need for public consultation. 296. The “Provisional Regulations on Public Participation in Environmental Impact Assessment” (2006) promulgated by State Environmental Protection Administration further improved the legislation of public participation in EIA in China. It provides detailed requirements for the public participation process, including information disclosure standards, consultation methods, and public enquiry process. It is significant since it was the first document clearly regulating public participation in EIA in China. 2 297. In 2014, former Ministry of Environmental Protection released “Guiding Opinions on Promoting Public Participation in Environmental Protection” (2014, No. 48) which defines public participation as ‘citizens, legal persons and other organizations’ voluntary participation in environmental legislation, enforcement, judicature and law obedience, and the development, utilization, protection and transformation activities related to environment. 2. ADB Requirements 298. ADB’s SPS (2009) has specific requirements for information disclosure and public consultation. Information disclosure involves delivering information about a proposed project to the general public and to affected communities and other stakeholders, beginning early in the project cycle and continuing throughout the life of the project. Information disclosure is intended to facilitate constructive engagement with affected communities and stakeholders over the life of the project. 299. The SPS requires that borrowers take a proactive disclosure approach and provide relevant information from environmental assessment documentation directly to affected peoples and stakeholders. In addition, in order to make key documents widely available to the general public, the SPS requires submission to ADB for posting on the ADB website as follows: (i) a draft full EIA (including the draft EMP) at least 120 days prior to ADB Board consideration for Category A projects, and/or environmental assessment and review frameworks before project appraisal, where applicable. 2 Wang Ya Nan, 2012. Public Participation in EIA, SEA and Environmental Planning in China. Environmental Impact Assessment Research Centre. - 125 - (ii) the final EIA/IEE. (iii) a new or updated EIA/IEE, EMP and corrective action plan prepared during project implementation, if any; and (iv) environmental monitoring reports. 300. The SPS also requires that the borrower carry out meaningful consultation with affected people and other concerned stakeholders, including civil society, and facilitate their informed participation. Consultations should include presentations on environmental impacts, benefits and mitigation measures, the project GRM, and ADB's Accountability Mechanism. For category A projects, such consultations should include consultations both at an early stage of EIA field work and when the draft EIA report is available. 7.2 Public participation process 301. According to the PRC and ADB requirements, public participation activities of the component included online information disclosure, consultation with related departments, questionnaire survey of APs, etc. a. Information Disclosure 302. The first online information disclosure of the EIA was conducted November 20, 2018 on the website of Wuhu City Traffic and Transportation Bureau (http://jtj.wuhu.gov.cn/Content.aspx?pNewID=4433&TypeID=111104 ), as shown in Figure 7.2-1. 303. The information includes the general profile and the alignment of the component, the contact information of IA and EIA preparation agency, contents of public participation. The online disclosure lasted for 10 days. Picture 7.2-1 Screenshot of Online announcement 304. Project Information was also disclosed near the affected towns and villages as well as environment sensitive areas. Meanwhile, component overview, EIA and public participation - 126 - issues have been informed and described to APs. Picture 7.2-2 Photos of Public participation 7.2.2 Public participation survey The contents of the survey are shown in Table 7.2-1 below. - 127 - Table 7.2-1 Survey contents Objects Main ways Contents 1.

According to Table 8.2-3, 70.59% of the respondents were between 36 and 59 years of age, 51.96% of the respondents were peasants, 29.41% of the respondents were workers, and the respondents were residents near the project area. In general, the composition of the public involved in the survey is reasonable, which can reflect the preference of the nearby public on the construction of the project. 308. According to Table 7.3-1, 61.74% of the respondents think that the project can promote the local economic development, and their main concerns are noise disturbance and air pollution during the construction and operation periods. They are also concerned about the ecological restoration of the components. None of the respondents opposed the construction of the component, and 100% of them agreed to the construction. 309. Public consultation is an ongoing process. During the construction period and within 3 years after the operation, public surveys will be conducted annually at sensitive receptors. 310. Based on the survey results, additional mitigation measures may be taken if needed. - 139 - 8 Grievance Redress Mechanism 311. A Grievance Redress Mechanism (GRM) will provide a convenient, transparent, fair and effective way to address the complaints of the APs. ADB’s GRM Requirements 312. The ADB’s SPS 2009 requires a project to establish a GRM to receive and facilitate resolution of AP’s concerns and complaints about the project’s environmental performance during construction as well as operation phases of the project. The GRM should be scaled to the risks and adverse impacts of the project; should address affected people’s concerns and complaints promptly, using an understandable and transparent process; should be readily accessible to the community at no cost and without retribution; and, should not impede access to the PRC’s judicial or administrative remedies. Current GRM Practices in the PRC 313. At the national level, a framework to address grievance has been established. State Council Decree No. 431 “Regulations on Letters and Visits” (January 2005) establishes a complaint mechanism at all levels of government, and safeguards the complainants from any retaliation. The former Ministry of Environmental Protection Decree No. 34 “Environmental Letters and Visits System” provides specific guidelines to establish a system and address environmental complaints. When APs are affected by project activities, they may complain to the contractors and the project company by themselves or through their community organizations, or complain directly to local EPBs. If the issue is not resolved they may take legal action, though that is typically considered as a last option. Project Level GRM 314. The objective of the component GRM is to prevent and address community concerns, reduce risks. In addition to serving as a platform to resolve grievances, the project level GRM has been designed to (i) open channels for effective communication, including the identification of new environmental issues of concern arising from the component; (ii) demonstrate concern about community members and their environmental well-being; and (iii) prevent and mitigate any adverse environmental impacts on communities caused by component implementation and operations. The GRM will be accessible to all members of the community through public information disclosure at IA’s website, component site and community centers, etc. 315. The overall approach of the GRM is to deal with grievances at a local level first in an efficient manner and escalate to higher level of authority if the grievance cannot be resolved. The designated person from the IA will be responsible for implementation of the GRM. 316. The GRM will be implemented through five escalating steps, advancing to the next level - 140 - only if the grievance was unable to be redressed at the previous level. (i) Step 1 : If a concern arises, the AP can try to resolve the issue of concern either directly with the contractors or via GRM access points (community leaders, IA, local EPB) during the construction phase, and/or IA during the operation phase. If the concern is resolved successfully no further follow-up action is required. Nonetheless, the contractors (during construction) and/or the IA (during operation) shall record any complaint and actions taken to resolve the issues and report the results to the EA and the AP. If no solution is found within 10 working days or if the AP is not satisfied with the suggested solution under Step 1, proceed to Step 2. The AP may also skip Step 1 and directly file the complaint with the PMO. (ii) Step 2: IA will record the grievance, assess its eligibility and report back to the AP within 5 working days.
