E. Construction Schedule
8. The total construction phase of the subproject will be approximately 18 months.
F. Description of the Environment
Location and Topography
9. Xi'an is the capital of Shaanxi Province and a sub-provincial city in northwest China. It is one of the oldest cities, the oldest prefecture capital and one of the Four Great Ancient Capitals in China, having held the position under several of the most important dynasties in Chinese history, including Western Zhou, Qin, Western Han, Sui, and Tang dynasty. Xi'an is the starting point of the Silk Road and home to the Terracotta Army of Emperor Qin Shi Huang.
10. Xi’an is situated in the “Guanzhong Plain” (known as the “800-mile basin”) which is the alluvial plain of the Weihe, Jinghe and Luohe Rivers with deep, fertile soil and rich agricultural production. Bordering the plain are the Qinling Mountain range in the south and Weibei Terrace region in the north, both of which contain abundant coal, metal and other non-metal mineral resources, and various natural resources.
11. Xi’an City is located at the south edge of the central part of the Weihe graben basin between Qinling Mountain in the south and Weihe River in the north on thick Tertiary and Quaternary unconsolidated deposits. The terrain is higher in the southeast and lower in the northwest, presenting a stepped decline along this gradient. Xi’an City has a flat relief at an altitude of 400 m.
Meteorology and Climate
12. Xi'an has a temperate climate that is influenced by the East Asian monsoon, and is classified under the Köppen climate classification as situated on the borderline between a semi- arid climate (BSk) and humid subtropical climate (Cwa). The Wei River valley is characterized by hot and humid summers, cold and dry winters, and dry springs and autumns. Most of the annual precipitation is delivered from July to late October. Snow occasionally falls in winter, but rarely settles for long. Dust storms often occur during March and April as the city rapidly warms up. Summer months also experience frequent but short thunderstorms. The monthly 24-hour average temperature ranges from around the freezing mark in January to 27.0°C in July, with an annual
3 mean of 14.08°C. With monthly percent possible sunshine ranging from 31 percent in December to 47 percent in August, the city receives 1,536 hours of bright sunshine annually. Extremes since 1951 have ranged from −20.6°C in January 11, 1955 to 41.8 °C in June 21, 1998. A highest record of 42.9°C was registered on June 17, 2006.
Water Resources
13. In ancient times, Chang’an (now knows as Xi’an) was famous for its eight rivers. Bahe River and Chanhe River in the east, Juehe River and Haohe River in the south, Zaohe River and Fenghe River in the west, and Weihe River and Jinghe River in the north of Xi’an. Besides, there are other big rivers such as Heihe River, Laohe River and Linghe River in Xi’an. Most of these rivers belong to the Weihe River system in the Yellow River Basin.
14. The subproject site is located at Chanhe River basin. The nearest river of the subproject is the Dayu River which is 1.5 km away from the subproject site in the east. Dayu River is a primary tributary of Kuyu River and the secondary tributary of the Chanhe River. Dayu River is classified as Class III surface water body.
Ecological and Sensitive Resources
15. The subproject has its surrounding area developed as urban development zone. Based on the site visit and collected information, there are no known rare or endangered flora or fauna, species with international, national or provincial protection status, areas of natural or critical habitat, parks, nature reserves, or areas with special national, regional or local ecological significance within or adjacent to any of the component site. There are also no known drinking water sources, scenic sites, or sites with Physical Cultural Resources (PCRs) based on site surveys and literature review.
16. The west boundary of the railway warehouse and logistics area is close to farmland and Fengqi Mountain Cemetery. The nearest sensitive receptors of the special railway line area is Gaozhai Village which is 100 m away in the east. The nearest sensitive receptors of the departure and arrival yard is Xinzhuang Village which is 15 m away in the east.
Socioeconomic Conditions
17. In 2019, gross domestic product (GDP) of Xi'an was 932.119 billion yuan, of which the primary sector accounted for 3.0% or CNY 27.913 billion; the secondary sector accounted for 34.0% or CNY 316.744 billion; and the tertiary sector accounted for 63.0% or CNY 587.462 billion Yuan. The GDP per capita was 92,256 yuan.
Physical Cultural Resources
18. Located in the middle of the Guanzhong Plain, Xi’an is one of the three international metropolises designated by China. In 2017, there were 3,246 immovable cultural relic sites and 392 cultural relic protection sites (including 52 national cultural relics protection sites, 105 provincial cultural relics protection sites, and 235 city and county-level cultural relics protection sites) in Xi’an, including 2 world cultural heritage sites and 4 national archaeological parks. Xi’an has 126 museums, including 34 state-owned museums, 45 industry museums, and 47 non-state- owned museums.

G. Anticipated Impacts and Mitigation Measures
19. Anticipated positive and negative environmental impacts of the subproject were assessed based on the domestic Feasibility Study Report (FSR), domestic environmental impact assessment (EIA) report; public consultations led by PIE and assisted by ADB technical assistance (TA) consultants; and site visits, surveys and consultations undertaken by PIE and ADB TA consultants.
20. Pre-construction, construction phase and operation phase of the subproject were assessed respectively. As the assessment results indicate that the environmental impacts are very limited in the pre-construction stage and are mostly associated with ensuring appropriate incorporation of mitigation measures into the project design.
21. Potential negative environmental impacts during construction phase are short-term and localized, and are associated with soil erosion, solid waste, wastewater, construction noise, fugitive dust, disruption of traffic and community services, and risks to workers and community health and safety. These can be effectively mitigated through good construction and health and safety practices
22. Potential negative impacts during operation phase are associated with air pollution from vehicles, solid waste, wastewater, noise, and health and safety risks to workers and community. These can be effectively mitigated through good operation of the subproject and health and safety practices.
23. Potential positive operation phase impacts are significant and long-term and are associated with emissions reductions through transportation mode transformation. Once operational, the subproject will: (i) improve the transportation model and efficiency and reduce traffic congestion in the urban area; (ii) promote regional industry cluster and increase employment rates of local residents; (iii) significantly reduce fossil fuel emissions of atmospheric pollutants such as NOx, PM2.5, and CO2.
H. Alternative Analysis
24. With the promotion of national and regional strategies such as Guanzhong Plain Urban Agglomeration Development Plan and China (Shaanxi) Pilot Free Trade Zone, Xi'an City is an important transportation and logistics node connecting the northwest region and the southwest region to the north China region.
25. Xi’an has a well-developed railway, highway and aviation transportation network, and has become an important hub in northwest China. At present, Xi’an has air routes to all provincial cities in China. There are direct flights from Xi'an to many major cities in Asia, including Bangkok, Busan, Fukuoka, Hong Kong, Kuala Lumpur, Manila, Osaka, Sapporo, Singapore Seoul, and Taipei. As a tourist city, Xi'an has built expressways to Lintong, Tongchuan and Baoji, with well- maintained roads to famous scenic spots in suburban counties and to the north slope of the Qinling Mountain. The National Expressway G108, 210, 211 and 312 passes through Xi’an City and of Xi’an City has a good highway transportation condition. Xi’an is classified as International Comprehensive Transport Hub by National Development and Reform Commission in 2018.
26. As a developing logistics park, Xi’an South Railway Station Logistics Park will provide more transportation service in the future with the development of Xi’an. The subproject will build
5 a rail-road multimodal bulk commodity logistics park to provide railway transportation service to Xi’an. Implementation of the subproject will: (i) improve the transportation model and efficiency and reduce traffic congestion in the urban area; (ii) promote regional industry cluster and increase employment rates of local residents; (iii) significantly reduce fossil fuel emissions of atmospheric pollutants such as NOx, PM2.5, and CO2.
I. Information Disclosure and Public Consultation
27. During preparation of domestic EIA, three rounds of information disclosure and public consultation were implemented. No public feedback was received during public information disclosure.
28. According to the requirements of ADB's SPS 2009, two public consultation meetings of this subproject were held in Yinzhen Town. The two meeting were held in nearest sensitive receptors - Gaozhai Village and Xinzhuang Village. The meeting in Gaozhai Village was held on October 31, 2019 and the meeting in Xinzhuang Village was on December 25, 2019. A public consultation meeting information notice was posted in two villages for one week prior to the meeting.
29. During the consultation, the PIE introduced relevant information such as project construction content and construction sites, and the EIA institute introduced the potential environmental impacts and mitigation measures during the construction and operation phases. While the participants believed that the subproject will improve their quality of life and provide more job opportunities to nearby residents.
30. During the two consultation meetings, a total of 32 questionnaires were distributed and 32 valid questionnaires were received. The questionnaires focused on potential environmental impacts and mitigation measures.
31. The overall support for the subproject is very strong,100% of the respondents support construction of the subproject; 81.3% of the respondents indicated that they accepted the anticipated environmental impacts and mitigation measures, 18.7% of respondents indicated that the top three environmental issues during the construction and operation phase they identified were dust during construction, noise during construction and operation and wastewater during construction.
32. Meaningful consultation will continue throughout detailed design, construction, and operation phases, including information disclosure by the PIE and posting of project information on village notice boards.
J. Grievance Redress Mechanism
33. During the construction and operation phase of the subproject, the PIE will establish a Grievance Redress Mechanism (GRM) to receive and assist in the resolution of complaints. GRM includes procedures for accepting complaints, recording key information, and evaluating and responding to complaints within a reasonable time frame. Any concerns of concern raised through GRM will be dealt with promptly and transparently without retaliation against the complainant.
K. Environmental Management Plan (EMP)
34. The subproject has developed a comprehensive EMP to ensure the implementation of
6 identified mitigation and management measures to avoid, mitigate and compensate for the expected adverse environmental impacts, the monitoring and reporting of monitoring indicators, and compliance with relevant environmental laws, standards and regulations in China, as well as SPS 2009. The EMP includes an environmental monitoring plan (EMoP) to monitor the environmental impacts and assess the effectiveness of mitigation measures, as well as capacity building and training programs focused on health, safety and the environment. EMP is shown in Appendix 1.
L. Risks and Key Assurances
35. The PIE of the subproject has limited experience in ADB's projects. To assist in the effective implementation of the EMP, the PIE will appoint a full-time management staff member for environmental and social affairs, meanwhile employ part-time Loan Implementation Environmental Consultant (LIEC) if needed. Pre-construction preparation and related institutional responsibility have been included in the EMP. All staff members are required to receive training on ADB environmental safeguard requirements and EMP implementation.
M. Conclusion
36. Through the environmental assessment process, it is concluded that the subproject has: (i) selected appropriate site and technologies to build one modern logistic park; (ii) identified potential negative environment impacts and established mitigation measures; (iii) received public support from the component beneficiaries and affected people; (iv) established project-level GRM procedures; and (v) prepared a comprehensive EMP including environmental management and supervision structure, environmental mitigation and monitoring plans, and capacity building and training.
37. Overall, any minimal adverse environmental impacts associated with the subproject can be prevented, reduced, or minimized through the appropriate application of mitigation measures.

II. POLICY, LEGAL AND ADMINISTRATIVE FRAMEWORK
10. This IEE is prepared on the basis of the national and local environmental legal and institutional framework of the People's Republic of China, environmental assessment requirements, and applicable ADB policies, regulations, requirements and procedures.
A. Applicable ADB Policies, Regulations and Requirements
11. The main applicable policies, regulations, requirements and procedures of ADB environmental assessment include SPS 2009 and Environmental Safeguards — A Good Practical Sourcebook (2012), which provide a basis for the report jointly. SPS 2009 promotes good international practices, as reflected in internationally recognized standards such as the World Bank (WB) Group's Environmental, Health and Safety (EHS) Guidelines.
12. SPS 2009 establishes the environmental examination procedure to ensure the implemented project (as a part of ADB loan aided project) is harmless to the environment and its design meets requirements of applicable laws and regulations, which is unlikely to cause environment, health, society or safety hazards.
13. At an early phase in the project cycle, typically the project identification phase, ADB screens and categorizes proposed projects based on the significance of potential impacts and risks. The environmental category of the project depends on the most sensitive environmental component, including direct, indirect, induced and accumulated impacts. Purposes of project screening and classification include:
(i) Reflect potential environmental impacts of the project;
(ii) Identify the type and level of EIA and institutional resources proportionate to the nature, scale, magnitude and sensitivity of the potential impacts of the proposed project; and
(iii) Confirm requirements of information disclosure and public participation.
14. ADB assigns a proposed project to one of the following categories:
(i) Category A. Proposed project is likely to have significant adverse environmental impacts that are irreversible, diverse, or unprecedented; impacts may affect an area larger than the sites or facilities subject to physical works. A full EIA including an EMP is required
(ii) Category B. Proposed project’s potential environmental impacts are less adverse and fewer in number than those of category A projects; impacts are site- specific, few if any of them are irreversible, and impacts can be readily addressed through mitigation measures. An IEE, including an EMP, is required.
(iii) Category C. Proposed project is likely to have minimal or no adverse environmental impacts. No EIA or IEE is required although environmental implications need to be reviewed.
(iv) Category FI. Proposed project involves the investment of ADB funds to, or through, a financial intermediary.
11
15. According to the requirements of SPS 2009, the subproject has been classified as environment category B and thus an IEE is required.
B. PRC Environmental Legal Framework
16. Environmental impact assessment system of the PRC is integrated into the system of environmental protection laws and regulations. Taking provisions of the environmental protection in Constitution of the People's Republic of China as its basis, basic laws of comprehensive links as its core and provisions of relevant laws about the environmental protection as its supplement, the system is a complete and relatively independent system of laws and regulations consisting of mutually related and coordinated environmental protection laws, regulations, rules, standards and international conventions. Laws and regulations applied to the subproject is presented in Table II-1.

C. PRC Environmental Impact Assessment Framework and Procedures
17. The Law of the People's Republic of China on Environmental Impact Assessment and the Catalogue for the Classified Administration of Environmental Impact Assessments for Construction Projects issued by the former Ministry of Environmental Protection stipulate which projects need to prepare environmental impact reports, which projects need to prepare environmental impact report forms and which projects only need to fill in environmental impact registration forms for filing. The Catalogue regulates:
(i) Category A: projects with significant adverse environmental impacts, for which a full EIA report is required;
(ii) Category B: projects with adverse environmental impacts which are of a lesser degree and/or significance than those of Category A, for which a simplified tabular EIA report is required; and
(iii) Category C: projects unlikely to have adverse environmental impacts, for which an EIA registration form is required.
18. The full EIA for Category A and the tabular EIA report for Category B are similar to the EIA and IEE reports of ADB, respectively. The EIA registration form is similar to the Category C project of ADB.
19. According to the original List of Classified Management of Environmental Impact Assessment for Construction Projects (promulgated on April 9, 2015, Decree No. 33 of the Ministry of Environmental Protection), a full EIA report shall be prepared for the subproject, while according to the modification list of Classified Management Directory of Construction Project Environmental Impact Assessment, (April 28, 2018), a tabular EIA report shall be prepared for the subproject.
20. The Ministry of Ecology and Environment (MEE) has issued a series of technical guidelines for the preparation of environmental impact assessments (Table II-2). These guidelines include guidelines for conducting environmental impact assessments, atmospheric and ambient air quality, noise, surface water, groundwater, ecological and regional biodiversity, biodiversity monitoring, quality management of environmental monitoring and public participation.

In 2019, the PIE changed its original project scope, including (i) the numbers of production lines of loading and unloading yard from two to three, (ii) the heating source from boilers to air conditioning; and (iii) the subproject implementation in two phases and the updated of floor area and total investment.
23. According to PRC’s Environmental Impact Assessment Law, any major changes in project scope must be reported to the original EIA approval authority and a new or updated domestic EIA must be submitted for approval again. On December 17, 2019, the PIE submitted a document to introduce the changes in scope to the Xi’an EEB (STTWLF [2019] No. 46) for approval. On December 20, 2019, Xi’an EEB made an official response (Figure II-2) to the PIE and confirmed that the changes in the subproject scopes were not major changes and the original domestic EIA was still effective.

F. Applicable PRC Environmental Standards
25. Environmental standards consist of environmental quality (ambient) standards applicable to the receiving environment and emission standards applicable to the pollution source. The former includes standards for ambient air quality, noise and vibration, surface water, groundwater, soil, etc. The latter includes standards for integrated wastewater discharge, waste gas emission, etc.

26. As noted above, ADB's SPS 2009 requires borrowers to comply with environmental standards of good international practice as reflected in internationally accepted standards (such as the World Bank Group's EHS Guidelines). When the regulations of the host country differ from these levels and measures, the borrowing country shall meet more stringent standards. In view of the specific circumstances of the project, if less stringent standards or measures are
17 appropriate, the borrower/client needs to justify any proposed alternatives. The evaluation uses PRC standards and EHS guidelines, as described below.
1. Ambient Air Quality Standards
27. The current PRC Ambient Air Quality Standards (GB3095-2012) divides the functions of ambient air into two categories: the first category refers to natural reserves, scenic spots and other areas that require special protection; the second category refers to residential areas, mixed areas of commercial, traffic and residential functions, cultural areas, industrial areas and rural area. The first category implements the Class I standard, and the second category implements the Class II standard. This subproject is located in the urban industrial zone, which belongs to the second category, therefore Class II standard is implemented.
28. The Air Quality Guidelines of the World Health Organization (WHO) are recognized international standards and adopted by the World Bank Group's EHS Guidelines. In addition to the guidance, WHO sets medium-term targets for each pollutant as incremental targets for the gradual reduction of air pollution. The WHO guidelines and corresponding PRC standards are set out in Table II-5.
Table II-5: PRC Ambient Air Quality Standards and WHO Ambient Air Quality Guidelines Unit: μg/m3 PRC Ambient Air Quality WHO/EHS Guidelines Air Quality Averaging Standard parameter period Interim Air quality Class I Class II Targets guideline Annual 80 200 NA NA TSP 24-hour 120 300 NA NA

29. It can be observed from Table II-5 that: for TSP and CO, there are PRC standards, but no corresponding WHO guidelines; for PM10 and PM2.5, PRC Class II annual average and 24-hour average standards meet WHO Interim IT-1 guidelines; for SO2, WHO only has a 24-hour average 3 3 guideline (125 μg/m ), which is slightly lower than the PRC standard (150μg/m ). However, SO2 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 NO2, there is no WHO 24-hour average guideline; and the 1-hour average PRC standard is equivalent to the WHO guideline. For O3, the PRC class I 1-hour average standard is equivalent to the WHO 1-hour average guideline and PRC 24-hour average class II standard is equivalent to the WHO Interim guideline 1 (IT-1).
30. 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 report except 24-hour average SO2 WHO guideline value.
2. Air pollutant discharge standards
31. During the construction stage, the dust emission shall meet the requirements in the Limit of Fugitive Dust Emissions from Construction Site (DB61/1078-2017, Table II-6), the exhaust gas emission during the operation phase shall comply with the Class II standard of Integrated Emission Standards for Air Pollutants (GB16297-1996, Table II-7), and the cooking fume from canteens shall comply with the Emission Standards of Cooking Fume (GB18483-2001, Table II- 8).

3. Wastewater Emission Standards
32. The EHS Guidelines indicate that wastewater discharged to public or private wastewater treatment systems should: i. meet the pretreatment and monitoring requirements of the sewer treatment system into which it discharges; ii. not interfere, directly or indirectly, with the operation and maintenance of the treatment systems, or pose a risk to worker health and safety, or adversely impact characteristics of residuals from wastewater treatment operations; and iii. be discharged into municipal or centralized wastewater treatment systems that have adequate capacity to meet local regulatory requirements for treatment of wastewater generated from the subproject.
33. Domestic wastewater generated by the subproject will be pretreated by the septic tank and discharged to the municipal sewage system. The wastewater discharges by the subproject will be required to meet Class III maximum acceptable concentrations (MACs) in Integrated Standards for Wastewater Discharge (GB8987-1996), and the Wastewater Treatment Plant (WWTP) discharges are required to meet Class 1A of Discharge Standard of Pollutants for Municipal WWTPs (GB 18918-2002). The Standards are shown in Table II-9.

4. Surface Water
34. PRC’s Surface Water Ambient Quality Standard (GB3838-2002) defines five water quality categories for different environmental functions. For example, Category I is the best, such as water at sources of rivers and National Nature Reserves. Category V is the worst, suitable only for agricultural and scenic water uses. Based on information collection and site visit, Category V water quality standards (see Table II-10) is applicable for the surface water near the subproject site. There are no applicable EHS guidelines or targets for water quality in this context, and the PRC standard is adopted for use in this IEE report.

5. Ground Water
35. PRC’s Groundwater Water Ambient Quality Standard (GB/T14848-2017) also defines a number of water quality categories for different environmental functions. As shallow groundwater near the subproject site is primarily used for irrigation, the Category III standard is applicable (Table II-11). There is no equivalent standard recommended in the EHS Guidelines, and the PRC standard is adopted for use in this IEE report.

6. Environmental Quality Standards for Noise
36. The comparison between the national standards (GB3096-2008) and the relevant international standards on acoustic environment is shown in Table II-12. The standards are not directly comparable, but the Class 1 national standard is equivalent to the Class I of the WHO standard and the class 2 and class 3 PRC standard are more stringent than Class II of the WHO standard. The east boundary of the freight yard is located within the range of 30-60m outside the center line of the Xi-kang Railway line, therefore Class 4a PRC standards is applied for the east boundary. The rest of site boundaries are located in Class 2 area and PRC Class 2 standard is applied.

IV. DESCRIPTION OF THE ENVIRONMENT
A. Location
60. The subproject is located in Xi’an South Railway Station Logistics Park, Yinzhen Town, Chang'an District, Xi’an City, Shaanxi Province.
B. Shaanxi Province Overview
61. Shaanxi Province is located in the northwestern part of China between 105°29 ~111°15 east longitude and 31°42 -39°35 north latitude. Shaanxi is generally long from north to south and narrow from east to west. The distance from north to south is about 880 km and from east to west is about 160-490 km. The province runs across two major river basins-Yellow River Basin and Yangtze River Basin. It is bordered by the Inner Mongolia Autonomous Region to the north, Shanxi province to the east, Henan and Hubei provinces to the southeast, Chongqing municipality and Sichuan province to the south, Gansu province to the west, and the Hui Autonomous Region of Ningxia to the northwest. The Yellow River constitutes Shaanxi’s entire eastern border with Shanxi. Shaanxi is an important portal connecting New Eurasian Continental Bridge to northwest, southwest, north, and central China. Shaanxi is the province with the largest number of neighboring provinces in China. The easternmost point of Shaanxi Province is located in Huangpu Town, Fugu County of Yulin City, the westernmost point is in Qingmuchuan Town, Ningqiang County of Hanzhong City, the southernmost point is in Huaping Town, Zhenping County of Ankang City, and the northernmost point is in Gucheng Town and Fugu County of Yulin City.
62. Shaanxi is divided into ten prefecture-level divisions including one sub-provincial city- Xi’an. The ten prefecture-level divisions are subdivided into 30 prefecture-level cities, six county- level divisions and seventy-one counties.
63. In 2019, the population of the province was 38.76 million. The land area is 205,600 km2. In 2019, Shaanxi’s GDP was CNY 2,579.317 billion, of which the primary sector accounted for 7.8% or CNY 199.093 billion; the secondary sector accounted for 46.4% or CNY 1,198.075 billion; and the tertiary sector accounted for 45.8% or CNY 1,182.149 billion.
64. Due to its large span in latitude, Shaanxi has a variety of climates. Under the Köppen climate classification, the northern parts, including the Loess Plateau, have either a cold arid or cold semi-arid, with cold and very dry winters, dry springs and autumns, and hot summers. The area known as Guanzhong is mostly semi-arid, though there are a few areas with a humid subtropical climate, with cool to cold winters, and hot and humid summers that often see early- season heatwaves. The southern portion is much more humid and lies in the humid subtropical zone, with more temperate winters and long, hot and humid summers. Annual mean temperature is roughly between 8 to 16°C, with January temperatures ranging from −11 to 3.5°C and July temperatures ranging from 21 to 28°C.
65. Shaanxi is considered one of the cradles of Chinese civilization. Thirteen feudal dynasties established their capitals in the province during a span of more than 1,100 years, from the Zhou Dynasty to the Tang Dynasty. The province's principal city and current capital, Xi'an, is one of the four great ancient capitals of China and is the eastern terminus of the Silk Road, which leads to Europe, the Arabian Peninsula and Africa. Under the Han Dynasty, the Northern Silk Road was expanded to advance exploration and military purposes to the west. This Northern Silk Road is the northernmost of the Silk Roads and is about 2,600 km in length. It connected the ancient
36
Chinese capital of Xi'an to the west over the Wushao Ling Pass to Wuwei and emerging in Kashgar before linking to ancient Parthia.
66. Shaanxi has abundant biological resources and outstanding diversity. Qinling and Bashan mountains are known as "biological gene bank". The diversity of ecosystems, species, and genetic genes in Shaanxi is typical and representative in China and even in East Asia. The province's forest land area is 12.26665 million hectares which ranks 10th in the PRC and the forest area is 8.533332 million hectares which ranks 11th in the PRC. The living wood growing stock in Shaanxi is 424 million m3, ranking 11th in the PRC. Natural forests are mainly distributed in Qinling, Bashan, Guanshan, Huanglong Mountain and Qiaoshan mountains. The grasslands belong to temperate grasslands and mainly distributed in northern Shaanxi. The wildlife resources are abundant in Shaanxi. There are 604 species of terrestrial vertebrates and 380 species of birds. Among them, 16 species including panda, golden monkey, takin, and cymbals are listed as national first-class protected wilds animals.
C. Xi’an City Overview

There are 113 plants, 422 genera, 701 species and 80 varieties of seed plants in the south of Nanwutai Mountain, which is 26 km away from the urban area. There are 121 families, 628 genera and about 1,550 species of seed plants at Taibai Mountain, the main peak of the Qinling Mountain. The seed plant species accounted for 40.20% of the total number of seed plants, 33.2% of the total genera, and 6.3% of the total species in the country. There are 138 families, 681 genera and 2,224 species of plants within the territory of the city. The natural vegetation and cultivated vegetation have clear boundaries. The Qinling Mountain are basically natural vegetation, while the Weihe Plain, the Lidongnan Hill and the Loess Tableland are cultivated vegetation. The distribution of the two vegetation areas is generally consistent with the landform.
92. The subproject site is located in developed area and natural vegetation has been removed
49
(Figure IV-6). Therefore, the ecological system at the subproject site is mainly the urban ecosystem.
93. According to the site investigation and information collection, domestic EIA, site surveys and records review, there are no known rare or endangered flora or fauna, species with international, national or provincial protection status, areas of natural or critical habitat,12F parks, nature reserves, or areas with special national, regional or local ecological significance within or adjacent to any of the subproject site. There are also no known drinking water sources, scenic sites, or sites with Physical Cultural Resources (PCRs) based on both sites surveys and literature review.

V. ANTICIPATED IMPACTS AND MITIGATION MEASURES
95. Anticipated positive and negative environmental impacts of the subproject were assessed based on the domestic FSR, domestic EIA; public consultations led by PIE and assisted by ADB technical assistance (TA) consultants; and site visits, surveys and consultations undertaken by ADB TA consultants.
96. Pre-construction, construction phase and operation phase of the subproject were assessed respectively. As the assessment results indicate that the environmental impacts are limited in the pre-construction stage and are mostly associated with ensuring appropriate incorporation of mitigation measures into the project design.
97. Potential negative environmental impacts during construction phase are short-term and localized, and are associated with soil erosion, solid waste, wastewater, construction noise, fugitive dust, disruption of traffic and community services, and risks to workers and community health and safety. These can be effectively mitigated through good construction and health and safety practices.
98. Potential negative impacts during operation phase are associated with air pollution from vehicles, solid waste, wastewater, noise, and health and safety risks to workers and community. These can be effectively mitigated through good operation of the subproject and health and safety practices
99. Potential positive operation phase impacts are significant and long-term and are associated with emissions reductions through transportation efficiency improvement. Once operational, the subproject will: (i) improve the transportation model and efficiency and reduce traffic congestion in the urban area; (ii) promote regional industry cluster and increase employment rates of local residents; (iii) significantly reduce fossil fuel consumption and emissions of atmospheric pollutants such as NOx, PM2.5, and CO2 and improve local air quality.
A. Pre-construction Measures shall be Implemented During Detailed Design
1. Siting and Land Acquisition
100. The subproject is located in Yinzhen Modern Logistics Park. The subproject site is construction land; therefore, the subproject will not result in any involuntary land acquisition, resettlement or physical displacement. There will be no loss of personal property, structures, crops, trees or other assets. There are also no potential adverse impacts on disadvantaged or vulnerable groups, including the poor, women and children, and Indigenous Peoples.
2. Mitigation Measures and Monitoring during Detailed Design
101. During the detailed design, the mitigation measures taken to minimize the impact are as follows:
(i) Detailed Design. Environmental mitigation and pollution control measures indicated in this IEE, the EMP and the domestic EIA will be incorporated into the detailed design.
(ii) Organization. An external Loan Implementation Environmental Consultant (LIEC) will be hired by the IA. A subproject PMO will be established by PIE with sufficient
53
staff responsible for environmental and social issues and an external Loan Implementation Environmental Consultant (LIEC) will be hired by the PMO if needed.
(iii) Training. Before the start of the construction, the LIEC will implement institutional strengthening and training programs. The training focuses on ADB and domestic related environmental, health and safety laws, regulations and policies, environmental management plan, environmental monitoring, and natural cultural resources and the implementation of the Grievance Redress Mechanism. The training targets are PIE, PMO and contractors.
(iv) Bidding documents and contracts. Environmental mitigation measures indicated in this EIA, the EMP and the domestic EIA will be included in contracts for civil works and equipment installations. All contractors will be required to strictly comply with the EMP. The subproject construction bidding documents shall contain the EMP, which the contractor shall all strictly abide by.
(v) Environmental monitoring. According to the relevant requirements of PRC and ADB, the environmental monitoring plan shall be formulated. The main monitoring targets of this subproject are noise and dust during construction phase and noise during operation phase.
3. Grievance Redress Mechanism
102. In accordance with the GRM presented in Chapter VIII of the IEE, a staff member from PIE will be assigned to be overall responsible for the GRM. GRM training will be provided for PMO, IA and PIE, and GRM access points. GRM access point phone numbers, fax numbers, addresses and emails will be disclosed to the public at the construction site.
4. Training and Capacity Building
103. A training plan is developed focusing on the implementation of relevant environmental, health and safety laws, regulations and policies, EMP, environmental monitoring, natural cultural resources and GRM and will be delivered by the LIEC. The training targets are subproject PMO, PIE, and contractors.
5. Permitting
104. All necessary permits have been obtained from the relevant authorities.
B. Anticipated Environmental impact and mitigation measures during the construction phase
105. Potential impacts during the construction phase could include air pollution, noise, water pollution, solid waste, and community and workers health and safety. Potential air quality impacts could occur due to fugitive dust generated at construction sites from stockpiles of uncovered earth materials, and vehicles hauling materials. The use of powered mechanical equipment during construction activities will generate noise. Construction activities will generate wastewater and construction workers will generate domestic wastewater. Stockpiles of construction waste is expected to have impact on the surrounding environment. Construction activities will produce construction waste and domestic waste. Workers will face occupational health and safety issues
54 working on construction sites. Identified impacts can be readily addressed through the application of good construction site practices.
1. Impacts on Flora and Fauna
106. Typical construction impacts on flora and fauna include removal of vegetation and disruption of the ecosystem during construction. If present, rare or endangered flora or fauna may also be impacted. However, the construction sites are located in urban environments with little or no vegetation cover other than recently established grasses and shrubs. It is therefore unlikely that there will be direct impacts on natural lands or ecological values from site developments.
107. Based on site visits, there is no known rare or endangered flora or fauna, parks, nature reserves or areas with special ecological significance which will be impacted by the subproject. Impacts on flora or fauna are thus expected to be minimal and short-term. Nonetheless, to address potential impacts, the following mitigation measures will be implemented.
(i) Site vegetation plan will be developed at subproject sites using appropriate local native species. (ii) Any existing greening areas impacted by the subproject will be restored post- construction using appropriate native species. (iii) During construction, construction working areas will be demarcated to prevent encroachment and damage to adjacent areas.
2. Erosion and Spoil
108. Construction activities such as land leveling, excavation and filling activities may lead to surface erosion. The most vulnerable soil erosion areas in the construction site include excavation sites, leveling sites, spoil sites, temporary construction sites, and other areas where surface soil is disturbed. Soil erosion can also be more serious on slopes or near water bodies. However, based on site visits, all construction sites are generally flat and there are no rivers, streams, ditches or lakes that are likely to be affected. Soil erosion can also occur after the completion of construction if site restoration is inadequate. Finally, construction activities may generate surplus spoil. Details of spoils generated from the subproject are given in Table V-1.
Table V-1: Magnitude of Earthworks for the Subproject Unit: 1,0000 m3
Earth excavation Earth backfill Spoil Spoil Disposal Spoil Spoil Xi’an Chang’an District Spoil 44 36 8 Disposal Site
109. These impacts can be mitigated through typical good construction practice as set out in EHS Guidelines on Construction and Decommissioning (C&D), erosion controls and site maintenance:
(i) At construction site, the potential for storm water runoff will be assessed and appropriate storm water drainage systems to minimize soil erosion will be implemented, including perimeter bunds and establishment of temporary detention
55
and settling ponds to control topsoil runoff. (ii) Land excavation and filling will be balanced so as minimize the requirement for fill material transportation. (iii) During earthworks, the area of soil exposed to potential erosion at any time will be minimized through good construction management practices. (iv) Temporary spoil storage sites will be identified, designed, and operated to minimize impacts. Spoil sites will be restored at the conclusion of storage activities. (v) Spoil will be reused on-site to the maximum extent feasible as fill. Excess spoil that cannot be used on-site will be transported to Xi’an Chang’an District Spoil Disposal Site. (vi) Spoil and aggregate piles will be covered with landscape material and/or regularly watered. (vii) Waste construction material such as residual concrete, asphalt, etc., will be properly handled for reuse or disposal. (viii) Construction and material handling activities will be limited or halted during periods of rains and high winds. (ix) Any planned paving or vegetating of areas will be done as soon as practical after the materials are removed to protect and stabilize the soil. (x) Once construction is complete disturbed surfaces will be properly sloped and revegetated with native trees and grass.
3. Wastewater
110. Inappropriate disposal of domestic wastewater (from construction workers) or construction wastewater (from oil-containing wastewater from machinery repairs) may cause soil or groundwater contamination.
111. Construction wastewater will be produced from the maintenance and cleaning of mechanical equipment and vehicles, and lost water and soil which is discharged as pollutants. It is unlikely that runoff from site will reach distant water bodies, however, to prevent runoff and infiltration from impacting the immediately surrounding areas, the contractors shall ensure that runoff from site will not reach distant water bodies.
112. Inappropriate disposal of construction wastewater (from construction site runoff, drainage of drilling, washing construction equipment and vehicles, pouring and curing concrete, and oil- containing wastewater from machinery repairs) could potentially pollute nearby water bodies and clog local drains. Workers will generate but limited amount of domestic wastewater.
113. To prevent pollution of water resources, the following mitigation measures and construction good practice as set out in EHS Guidelines on C&D, will be implemented:
(i) Worker camp will be installed with sufficient toilets which will be provided for the workers and domestic wastewater will be treated in septic tank and discharged to the municipal sewerage system on a regular basis. Once the construction starts, if it is found that toilets are not enough or there are female workers, more toilets will be provided.
56
(ii) Construction wastewater will be directed to temporary detention and settling ponds, and the treated water will be partly recycled for use in dust control and the rest of treated water will be discharged to the local municipal sewer system and the waste residue in the tank is cleaned and transported to designated certificated and engineered landfill by the local sanitation department. If needed, polyacrylamide flocculent will be used to facilitate particle settling. All discharged construction wastewater will to be treated to meet the appropriate PRC standard GB/T 31962-2015 prior to discharge. Discharged water will then be treated in the municipal WWTP. (iii) All necessary measures will be undertaken to prevent construction materials and waste from entering drains and water bodies. (iv) Maintenance of construction equipment and vehicles will not be allowed on sites to reduce wastewater generation. (v) Oil traps are provided for service areas and parking areas, and oil-water separators are installed before the sedimentation tank for oil-containing wastewater. (vi) All construction machinery is repaired and washed at special repairing shops. No on-site machine repair, maintenance and washing shall be allowed so as to reduce wastewater generation. (vii) Storage facilities for fuels, oil and other hazardous materials if applicable are within secured areas on impermeable surfaces with 110% volume of the materials stored, and provided with bunds and cleanup kits. (viii) The contractors’ fuel suppliers are properly licensed, follow proper protocol for transferring fuel, and are in compliance with Transportation, Loading and Unloading of Dangerous or Harmful Goods (JT 3145-88).
4. Air Pollution
(i) Analysis of the impact of fugitive dust generated by vehicle transportation
114. The fugitive dust transported by the vehicle accounts for about 30% of the total fugitive dust generated. In the complete dryness condition, fugitive dust quantity is calculated according to the following empirical formula:
Q=0.123ͧV/5ͨ(W/6.8)0.85(P/0.5)0.75
In the formula: Q--the fugitive dust of the car, kg/km·per car; V--car speed, km/h; W--car weight, t; P--the amount of dust on the road surface, kg/m2.
115. Table V-2 shows the amount of fugitive dust generated by a truck with a capacity of 5 tons passing a road of 500m at different road cleaning levels and at different driving speeds.
57
Table V-2: Vehicle Fugitive Dust Units at Different Speeds under Road Cleaning Conditions (Unit: kg/car·km) 0.1 0.2 0.3 0.4 0.5 1.0 Speed ˄kg/m2˅ ˄kg/m2˅ ˄kg/m2˅ ˄kg/m2˅ ˄kg/m2˅ ˄kg/m2˅ 5(km/h) 0.0283 0.0476 0.0646 0.0801 0.0947 0.1593

20(km/h) 0.1133 0.1905 0.2583 0.3204 0.3788 0.6371 Source: ADB TA consultants
116. The results show that in the same road cleaning levels, the faster the speed is, the more fugitive dust is generated; and at the same speed, the worse the road cleaning level is, the more fugitive dust is generated.
117. If the road is sprayed with water regularly, the dust will be reduced. If the water is sprayed 4~5 times every day, the fugitive dust can be reduced by about 70%. Table V-2 shows the test results of water spraying at the construction site. It presents that 4~5 times of water spray at the construction sites every day can effectively control the construction fugitive dust, and impacts range of the TSP will be less than 50m and the TSP concentration can meet the hourly average concentration limit in Table 1 of the Fugitive Dust Emission Limit of Construction Site (DB61/1078- 2017), no more than 0.7mg/m3. Therefore, limit of vehicle speed, maintenance of road and proper water spray are effective means to reduce vehicle fugitive dust.

(ii) Impact of construction dust from outdoor stockpiles and uncovered construction sites
118. The fugitive dust caused by wind in the outdoor stockpiles and uncovered construction sites accounts for about 70% of the total dust generated. Due to the construction needs, some building materials need to be stacked outdoor. Some construction sites need to be excavated and stacked manually, where dust is generated in the case of dry climate and windy conditions.
119. The spreading and diffusion of dust particles in the air are related to meteorological conditions such as wind speed, and the sedimentation velocity of the dust particles. Taking sand and dust as an example, the sedimentation velocity increases rapidly with the increasement of particle size. When the particle size is 250μm, the sedimentation velocity is 1.005 m/s. Therefore, when the particle size is larger than 250μm, the main impact range of the dust is within the close range of the fugitive dust generation point in downwind direction and the impacts are mainly from the micro and small particles.
120. The construction fugitive dust size varies greatly based on the construction season, the amount of earthwork and the construct particles, and the impact range can reach 150~300m.
58
Through the analogy investigation and analysis, under the general meteorological conditions, when the average wind speed is 2.5m/s, the construction fugitive dust can result in:
i. The TSP concentration at the construction site is 1.5~2.3 times of the reference point in the upwind direction; ii. The TSP concentration at the point which is 150m way from the construction site in the downwind direction is 0.49mg/m3 equivalent to 1.6 times of the limit; iii. Fence can reduce construction fugitive dust pollution. When the wind speed is 2.5m/s, the impact range can be reduced by about 40%.
121. The construction work activities may destroy the soil surface, expose the land and loosen the soil and provide good conditions for fugitive dust generation. The subproject area belongs to a temperate continental monsoon climate with less rainfall and more dryness and wind in spring and winter seasons. Some study pointed that fugitive dust caused by windy weather leads to high concentration of TSP in the atmospheric environment, among which construction sites contribute most. Therefore, fugitive dust pollution is one of the main environmental problems during the construction phase.
(iii) Mitigation Measures for Ambient Air Quality Impact
122. The subproject is located in the urban area. In order to reduce the impacts of construction fugitive dust during construction, the contractors should strictly follow the Fugitive Dust Emission Limit of Construction Site Boundary (DB61/1078 -2017), Work Plan for the Blue Sky Defense War of Shaanxi Province in 2019, and other relevant provisions such as the Regulations on the Prevention and Control of Air Pollution in Shaanxi Province. The main prevention measures for construction fugitive dust are as follows:
(i) Water will be sprayed on active construction sites including where fugitive dust is being generated on a daily basis, and more frequently during windy days. (ii) Transport vehicles will be limited to low speeds at the construction sites. (iii) Loads will be covered during truck transportation to avoid spillage or fugitive dust generation. Fine materials will be transported in fully contained trucks. (iv) Construction site roads will be well maintained and watered and swept on an as- needed basis. Construction site road entry points will be equipped with truck drive through wash ponds. (v) Transport routes and delivery schedules will be planned to avoid densely populated and sensitive areas, and high traffic times. (vi) Store petroleum or other harmful materials in appropriate places and cover to minimize fugitive dust and emission. (vii) Provide regular maintenance to vehicles in order to limit gaseous emissions (to be done off-site). (viii) Temporary fencing will be erected around dusty activities. (ix) Construction spoil, aggregate other construction materials will be temporary stored using containers, but they may still have the potential to generate dust. Thus, containers will be covered and/or watered if necessary. Powdered materials such as cement and lime will be stored in sealed bags or containers. (x) Muddy or dusty materials on public roads outside the exits of works areas will be
59
cleaned immediately. (xi) On-site asphalting and concrete batching are prohibited. (xii) Fence will be installed at site boundaries and dust monitoring will be implemented at sensitive receptors to ensure compliance.
(xiii) Disturbed site will be revegetated as soon as possible after the completion of works.
5. Noise
123. According to the nature of the subproject, the noise sources of the construction activities at the construction sites are shown in Table V-4.
Table V-4: Noise Sources of the Construction Machinery Measuring point No. Name of Device A sound level (dB(A)) distance (m) 1 Drill pile machine 109 2 Concrete pump 85 3 Concrete vibrating machine 84 4 Tire hydraulic excavator 84 5 Grader 90 D=5 6 bulldozer 86 7 Vibratory roller 86 8 Double wheel double vibrating roller 87 9 Three-wheel roller 81 10 Tire roller 76 Source: ADB TA consultants
124. According to the data in Table V-3, the noise from the drilling machine is the highest among the construction machinery, up to 109dB(A) at 5m from the sound source, and the remaining sound level of most construction machinery is between 76~90dB(A). .
125. According to the noise attenuation formula of point source, the noise level at the different distances from the point noise source r is:
r Lp r =Lp r0 -20lg r0 In the formula: Lp r -- the sound pressure level of the noise source at the predicted point, dB(A);
Lp r0 -- Sound pressure level at the point of reference location , dB(A);
