EXECUTIVE SUMMARY 1. Introduction

1. This Updated IEE Report for Rehabilitation and Reconstruction of 43km Kangurt to Baljuvon to Intersection of Vose-Khovaling Road Rehabilitation and Reconstruction supersedes the previous IEE prepared in May 2018. The basis of this update is change in project scope of work including reconstruction of existing metal Bridge No.5 and Bridge No.6 to RCC type, including rehabilitation of 4 bridges. The Supplementary IEE prepared in December 2018 for 2 Bridges has been integrated into this Updated IEE study.

2. An impact assessment process has been conducted for the proposed rehabilitation of 43 km of rural road in the Khatlon Region of Tajikistan. The current road is in a poor state of repair, with wearing course absent or deeply rutted, and in some locations water erosion has removed the road bed in its entirety. The road runs from Kangurt, through Baljuvon and ends at the intersection with the Vose-Khovaling Road at km 23 (Vose-Khovaling Road), which itself was recently rehabilitated.

3. The road connects local communities with each other and to the wider region. The poor condition of the road makes journey times longer, causes undue wear and tear on vehicles and increases risk of traffic accidents due to the unsuitable surfaces and vehicles driving on the wrong side of the road.

4. The objectives of the Kangurt to Baljuvon and Baljuvon to intersection Vose-Khovaling Road rehabilitation are to assist the socioeconomic development of the Baljuvon District by improving transport infrastructure in the region. The project is expected to increase trading and associated commercial activities, tourism opportunity, promote animal rearing, enhance in agricultural productivity, develop human capital, and reduce poverty. It is designed to benefit isolated beneficiary communities by improving their access to markets, social services, and health facilities, and by expanding their livelihoods to cover off-farm jobs including provision of transport services and road maintenance.

5. Part financing of the road is through an existing grant from the Asian Development Bank. Money has become available through savings on other road projects and the Ministry of Transport has determined that best value for the remaining grant can be achieved through the rehabilitation of the KanРurt to KСovaХТnР IntОrsОМtТon roaН. In aММorНanМО аТtС ADψ’s EnvТronmОntaХ SaПОРuarН PoХТМв, Тt Тs nОМОssarв to МonНuМt an ТmpaМt assОssmОnt oП tСО proУОМt proposaХs as part oП ADψ’s approval process for financial spend.

6. A screening process for the project determined that it fell within Category B for the purposed of impact assessment, in accordance with ADB categorization. This means that an appropriately scoped impact assessment was required and presented as an Initial Environmental Examination (IEE) Report in May 2018. The present Updated IEE incorporates the replacement of existing metal bridges into RCC with 2 lanes, accordingly reconstruction of Bridge No.5 and Bridge No.6 is planned.


_____________________________________________________________________________


7. As such, this current document is the Updated IEE Report for the Project. It has been produced by the Project Implementation Unit of the Tajikistan Ministry of Transport and their consultants, SMEC. The report is submitted to ADB for approval.

2. Description of the Project

8. The project entails complete rehabilitation of the existing road bed and wearing courses. The rehabilitation will not entail widening of the road, except in some minor locations where road curvature is being eased by minor realignment. The project remains within the existing length of 43 km Right of Way and no new land take is required, even for the reconstruction of the Bridge No. 5 and Bridge No. 6.

9. The project proposal includes the rehabilitation of four bridges and 27 culverts which cross water courses, the remaining 2 metal Bridges (Bridge No. 5 and Bridge No. 6) will be reconstructed in to RCC type. A new raised embanked road bed of 1.6 km (approach to Bridge No.6) will be developed within the flood plain to the east of Baljuvon where the old road has been completely lost due to water erosion. Scour protection within the flood plain and at bridge abutments will be developed. The project has developed a comprehensive hydrological study to aid design of these structures and ensure the project does not cause upstream flooding by blocking the water courses during river spate conditions.

10. The existing, and the new road, consists of two lanes only and is a Category IV road in accordance with Tajikistan Standards for Highways.

3. Overview of the Receiving Environment

11. The road alignment runs through predominantly agricultural land, with much of this being arable land, with some permanent pasture and woody scrub in the higher elevations, with small areas of fruit orchards present.

12. The land within the project area is fertile and receives good regular rainfall with high humidity. It has been the focus of agricultural activity for thousands of years. This means that ecologically the project area has limited value with no evidence of natural habitat present.

13. The road verge itself is mainly grass sward with some encroaching woody species in the form of thorn bushes (Crataegus) and wild almond and fruit trees.

14. The landscape is rolling, and in some locations deeply incised and the original route has cut through small hills creating deep cuts.

15. No evidence of archaeological resources was recorded within the vicinity of the road. It is likely that regular tilling of the soils has eradicated any trace of former use.

16. Along the route there are a number of settlements, although a feature of the area is for villages to be set off from the road, thus reducing the number of potential environmental receptors


_____________________________________________________________________________


along the route. Very few sensitive receptors are present, with no schools near to the road and a mosque at some 50 m from the road behind other screening buildings.

17. Current traffic movements on the route are light, at approximately 496 to 506 movements per day along the entire route. Approximately 6% of the movements are heavy vehicles. Through movements of heavy vehicles are restricted as one of the bridges in the Baljuvon flood plain is both weight and width limited, the latter at 5 m.

18. A significant feature of the project is water resources, both in the form of spring lines, some of which are used as water supply for local residents, and the three rivers.

4. Scoping

19. A scoping study was conducted for the project and the below table provides a summary of the impact assessment scope.

20. In order to establish the existing and expected noise levels, noise modeling was undertaken at four stages: (i) noise level modeling for the existing situation, (ii) noise level modeling for the construction stage, (iii) noise level modeling at the operation stage by 2019, and (iv) noise level modeling at the operation stage by 2025 and 2033.

21. Modeling was done by using computer software CadnaA. CadnaA (Computer Aided Noise Abatement) is the leading software for calculation, presentation, assessment and prediction of environmental noise. Whether your objective is to study the noise emission of an industrial plant,


_____________________________________________________________________________


of a mart including a parking lot, of a new road or railway scheme or even of entire towns and urbanized areas: CadnaA is designed to handle all these tasks.

22. As the results of the baseline measurements and modeling demonstrate, the noise level, besides some exceptions, was within the norm near all buildings and premises found in the project zone. In line with the modeling results, for 53 of 755 buildings (7 %), the noise level exceeded the admissible level, during the day and/or at night.

23. During the construction phase, the noise level increases and it will be higher than the admissible level at 445 (58.9%) buildings during the day. However, latest noise monitoring has indicated noise levels to be within the standards. Moreover, no construction works will be carried out during night. Furthermore, the impact of noise will be short-term and relevant mitigation measures will be developed within the scope of the project; In addition, noise monitoring will also be carried out during the construction of bridges to determine any exceedances in noise levels from the standards. Lastly, implementation of site- specific noise management plan will also ensure any adversity of this impact is minimized

24. In line with the modeling results, in the operation phase, the noise level will not exceed the admissible level at any of the buildings, either following the project implementation or in 2025 and 2033.

25. It is also noted that while the rehabilitation will improve access for local residents, it is not anticipated to induce traffic from outside the area. The 3% increase is based on natural growth and comes from a World Bank study where they predict a 3% increase in Gross Domestic Product (GDP) with a concomitant increase in road traffic of the same percentage.

5. Impact Assessment Process and Results

26. Following scoping of the study, Valued Environmental Receptors (VERs) to be included in the assessment process were identified. In total 20 VER;s were considered in the impact assessment process.

27. Based on a review of the projects activities during construction and the operational phase, tСО potОntТaХ ТmpaМts on tСОsО VER’s аas assОssОН. ImpaМts аОrО ТНОntТПТОН anН usТnР a ПormaХ scoring system, impact severity was determined. The magnitude of the severity and the consequence of the impact on the VER was determined using a two-dimensional matrix.

28. Impact significance was determined without mitigation in place and reassessed based on one or more mitigation measures being implemented to reduce the severity of the significant effect.

29. In total 30 environmental effects acting on the VER;s were identified. Of these 24 were considered significant without mitigation. Mitigation measures which are commensurate with the environmental effect have been developed and set out in the IEE as project commitments. Providing all mitigation is fully implanted there remains only four residual significant effects or risks. Two of these are positive benefits of the road, related to improved access and safety for local road users. Two residual significant residual and adverse effects were identified. These are


_____________________________________________________________________________


better expressed as risks and occur during the operational phase of the project and a focus on ensuring implementation of the mitigation measure will effectively control the risk. These also relates to diffuse and point source contamination of local water courses from road storm water runoff. Again, effective maintenance of installed drains and settlement pits will manage this risk.

6. Implementation

30. The Updated IEE, its mitigation and monitoring programs, contained herewith shall be included within the Project Bidding documents for project works. The Bid documents state that the Contractor shall be responsible for the implementation of the requirements of the EMP through his own Site Specific Environmental Management Plan which will adopt all of the conditions of the EMP and add site specific elements that are not currently known, such as the Contractors final list of borrow pit locations. This ensures that all potential bidders are aware of the environmental requirements of the Project and its associated environmental costs.

31. The EMP and all its requirements will then be added to the Contractors Contract, thereby making implementation of the EMP a legal requirement according to the Contract. He shall then prepare his SSEMP which will be approved and monitored by the Engineer. Should the Engineer note any non-conformance with the SSEMP the Contractor can be held liable for breach of the contractual obligations of the EMP. To ensure compliance with the SSEMP the Contractor should employ a national environmental specialist to monitor and report Project activities throughout the Project Construction phase.

32. The EMP, its mitigation and monitoring programs, contained herewith shall be included within the Bidding documents for project works for the proposed road rehabilitation and reconstruction of 2 new RCC Bridges.

7. Monitoring Actions

33. To ensure that all of the above mitigation actions are completed according to the requirements of the EMP, monitoring shall be undertaken of Project works by the Engineer and by independent monitoring specialists. Specifically, both observational monitoring and instrumental monitoring shall be undertaken on the Road:

• Instrumental Monitoring – This shall be completed by independent specialists and will include

air quality monitoring and water quality monitoring at the pre-construction and construction

phases and noise quality monitoring at the construction phase. Schedules, parameters,

locations are indicated by the Updated IEE EMP and shall be adopted by the Contractors SSEMP.

• Observational Monitoring – The Contractors actions shall be continually monitored by the Engineer throughout the Projects Construction phase. This will be achieved through weekly inspections of the Contractors environmental performance by national and international environmental specialists engaged by the Engineer throughout the construction period. The Engineer shall have the right to suspend works or payments if the Contractor is in violation of any of his obligations under the EMP and this Updated IEE.

8. Conclusion

34. The impact assessment process indicates that the road rehabilitation, and 2 new RCC Bridges reconstruction by replacing existing metal bridges project, with proper controls during the implementation period will not have significantly adverse environmental effects.

35. This conclusion is based on all committed mitigation being fully implemented, the development of effective SSEMPs and auditing of the work to ensure good environmental performance and adherence to the EMP requirements.

36. The EMP, its mitigation and monitoring programs, contained herewith shall be included within the Bidding documents for project works for the new construction of RCC Bridge No5 and Bridge No 6 of Baljuvon. The new design changes will not add any new activities, shifting of Bridge No 6 will bring positive impacts in terms of less adverse impacts on aquatic resources. Based on the assessed design, the results of the Updated IEE indicate that the project has a limited risk of causing significant environmental impacts Moreover, the impacts will be site-specific and temporary in nature, and there are no substantive environmental reasons for the project not to proceed. As such, it is recommended that, the interventions should go ahead as soon as possible considering the environmental Acts and Rules of the Republic of Tajikistan and ADB safeguard Policy Statement 2009.

I. INTRODUCTION

1. Preamble

37. This Updated IEE Report for Rehabilitation and Reconstruction of 43km Kangurt to Baljuvon to Intersection of Vose-Khovaling Road Rehabilitation and Reconstruction supersedes the previous IEE developed in May 2018. The basis of this update is change in project scope of work including reconstruction of existing metal Bridge No.5 and Bridge No.6 to RCC type, including rehabilitation of 4 bridges. The Supplementary IEE prepared in December 2018 for 2 Bridges has been integrated into this Updated IEE study.

38. The Tajikistan Government is in receipt of a 70 million USD grant from the Asian Development Bank (ADB) for rehabilitation of rural roads within the country. As part of the program of rehabilitation, Grant No 0356 Taj, has achieved a saving over the predicted costs for allocated routes. This saving, plus a direct contribution from the Tajikistan Government is being used to provide rehabilitation of a 43 km section of road within the Khatlon Region of the country (see Figure 1). The project is for rehabilitation of a two-lane rural road which runs from the town of Kangurt in a mainly eastwards direction, passing through Buljuvon, to the junction with the recently upgraded Kovaling Road at km 23 (Vose-Khovaling Road).

39. In aММorНanМО аТtС tСО rОquТrОmОnts oП ADψ’s EnvТronmОntaХ SaПОРuarНs rОХatТnР to Хoans and grants, an impact assessment process has been conducted for the project. The results of the impact assessment process are presented in this Updated IEE document.

40. The Government of Tajikistan, through the Ministry of Transport submits this impact assessment to ADB for approval.

41. The project has been classed as a Category B project for the purposes of impact assessment, requiring that the impact assessment be presented in the form of an Initial Environmental Examination (IEE) report. See Section 1.2 for additional information on the Impact Assessment screening.

2. Need for an Impact Assessment and Screening

42. The project consists of a 43 km road rehabilitation in a rural setting. The need for an impact assessment process is driven by National law and ADB policy. The national requirement Пor ОnvТronmОntaХ ТmpaМt assОssmОnt Тs ОnsСrТnОН аТtСТn TaУТФТstan’s “δaа on EnvТronmОnt ProtОМtТon” (қ0ҚҚ) anН tСО “δaа on EМoХoРТМaХ EбpОrtТsО” (қ0ҚҚ).

43. In addition, ADB in 2009 established its Safeguard Policy Statements, which include Environmental Safeguards (Asian Development Bank, 2009). Included within the ADB Environmental Safeguards is a need to screen projects based on their risk of significantly affecting environmental receptors and causing long term harm.


_____________________________________________________________________________


44. The ADB processes utilizes three categories for determination of the projects impact assessment requirements. Three main categories are utilized, these being Category A, B or C. Category C is for projects which are considered to present no direct risk to environmental receptors. The definitions of Category A and B projects are set out below:

A project is defined as Category A – … ТП Тt Тs ХТФОХв to СavО sТРnТПТМant aНvОrsО environmental impacts that are irreversible, diverse or unprecedented. These impacts may affect an area larger than the sites or facilities subject to physical works. A project is defined as Category B - … ТП Тts potОntТaХ aНvОrsО ОnvТronmОntaХ ТmpaМts are less adverse than those of Category A projects. These impacts are site-specific, few if any of them are irreversible and in most cases mitigation measures can be designed more readily than for Category A Projects.

45. The current project was reviewed for potential adverse impacts in order to determine the ADB Project Category for Impact Assessment. The project was screened for potential impacts based on knowledge of the proposed project (land take requirements, construction activities and operational parameters), the receiving environment and experience of similar projects within similar settings.

46. The Kangurt to Khovaling Intersection road rehabilitation project was determined to be a Category B project for impact assessment purposes. The principle reasons for this categorization are:

Project is for rehabilitation of existing route, which removes possible significant environmental effects of new roads such as community severance, habitat fragmentation and severance, exposure of receptors to new impacts such as air quality.

Project does not require any additional land take and involves minimum widening of the existing alignment in only a few locations but remaining within the existing Right of Way. The Bridge No 5 will be reconstructed in its original location and Bridge No.6 will be slightly skewed. However, no additional land is required for both the Bridges.

The project when operational is predicted to give rise to only slight increases of induced additional traffic flows. Although the nature of the road is highly rural with inclines and bends, the upgraded conditions of the road and bridges with two-way traffic will enhance safe movement of the people.

Predicted effects are considered to be site specific, can be readily mitigated and do not involve impacts that are unprecedented of irreversible.

47. TСО ТmpaМt assОssmОnt Сas aММorНТnРХв bООn МonНuМtОН Тn ХТnО аТtС ADψ’s rОquТrОmОnts for submission of an Updated IEE Report. It is noted that this does not imply that a lesser quality impact assessment is acceptable. The project has been effectively scoped (see Section III) and where scoped in, specialist topics have been appropriately assessed and reported.

3.1. Framework environment law

57. The new Law on environment protection stipulates that Tajikistan's environmental policy should give priority to environmental actions based on scientifically proven principles to combine economic and other activities that may have an impact on the environment, with nature preservation and the sustainable use of resources. The Law defines the applicable legal principles, the protected objects, the competencies and roles of the Government, the Committee for Environmental Protection under Government of Tajikistan, the local authorities, public organizations and individuals.

58. The Law also stipulates measures to secure public and individual rights to a safe and healthy environment and requires a combined system of ecological expertise and environmental impact assessment of any activity that could have a negative impact on the environment. The Law also defines environmental emergencies and ecological disasters and prescribes the order of actions in such situations, defines the obligations of officials and enterprises to prevent and eliminate the consequences, as well as the liabilities of persons or organizations that caused damage to the environment or otherwise violated the Law. The Law establishes several types of controls over compliance with environmental legislation: State control, ministerial control, enterprise control and public control. State control is affected by, the Sanitary Inspectorate of the Ministry of Health, the Inspectorate for Industrial Safety and the Mining Inspectorate. Public


_____________________________________________________________________________


control is carried out by public organizations or trade unions and can be exercised with respect to any governmental body, enterprise, entity or individual.

4. Legal Framework for Environmental Assessment (EA) and Permitting

4.1 Basic EA Laws.

59. There are two laws in the country that stipulate all aspects of the EA:

(a) Law on Environment Protection; and

(b) Law on Ecological Expertise.

60. The Chapter V, Articles 35-39 of the Law on Environment Protection (2011), introduces tСО МonМОpt oП statО ОМoХoРТМaХ rОvТОа (ХТtОraХХв, statО ОМoХoРТМaХ “ОбpОrtТsО” – SEE) that seeks to examine the compliance of proposed activities and projects with the requirements of environmental legislation and standards and ecological security of the society. The mentioned laws stipulate the mandatory cross-sectoral nature of SEE, which shall be scientifically justified, comprehensive, and objective and which shall lead to conclusions in accordance with the law. SEE precedes decision-making about activities that may have a negative impact on the environment. Financing of programs and projects is allowed only after a positive SEE finding, or conclusion, has been issued.

61. The following activities and projects subject to state ecological review:

a. draft state programs, pre-planning, pre-project, and design documentation for economic development;

b. regional and sectoral development programs; c. spatial and urban planning, development, and design; d. environmental programs and projects; e. construction and reconstruction of various types of facilities irrespective of their

ownership; f. draft environmental quality standards and other normative, technology, and

methodological documentation that regulates economic activities; g. existing enterprises and economic entities.

62. The laws stipulate that all types of economic and other activities shall be implemented in accordance with existing environmental standards and norms and shall have sufficient environmental protection and mitigation measures to prevent and avoid pollution and enhance environmental quality. The EA studies analyzing the short- and long-term environmental, genetic, economic, and demographic impacts and consequences shall be evaluated prior to making decisions on the allocation, construction, or reconstruction of facilities, irrespective of their ownership. If these requirements are violated, construction will be terminated until necessary improvements are made, as prescribed by the GoT and/or other duly authorized control bodies, such as sanitary, geological, and public safety agencies.

63. An EIA is a component of the SEE, as set out in the 2011 Environmental Protection Law and in the 2012 Law on State Ecological Expertise, which comprises both the department within


_____________________________________________________________________________


the Committee for Environmental and the process as well. Conducting the EIA is the responsibility of the project proponent. The State Ecological Review 1 - which comprises the process component only - for all investment projects is the responsibility of the GoT Committee for Environmental Protection (CEP) and its regional offices. Furthermore, according to the 2012 Law on State Ecological Expertise, all civil works, including rehabilitation ones, should be assessed for their environmental impacts and the proposed mitigation measures should be reviewed and monitored by the CEP.

64. According to the 2012 Law on Ecological Expertise, ecological expertise is intended to prevent negative impacts on the environment as a result of a proposed activity, forecast impacts from activities that are not considered as necessarily damaging to the environment and create databases on the state of the environment and knowledge about human impact on the environment.

65. This Law on Ecological Expertise and the Law on Environment Protection envisage two types of ecological expertise – State ecological expertise and public ecological expertise, which are not given equal importance. While State ecological expertise is a prerequisite for beginning any activity that may have an adverse environmental impact, public ecological expertise becomes binding only after its results have been approved by a State ecological expertise body.

66. The State Ecological Expertise is authorized to invite leading scientists and qualified outside specialists to participate in the review. Approval should be issued within 30 days, unless the project developer agrees to an extension, and remains valid for two years, if the decision is positive. For very complicated projects the term of consideration and approval can be extended till 60 days.

67. According to the Law on SEE the public ecological expertise of economic activities or other activities implementation of which can negatively impact the environment of population which live in relevant area can be carried out by any public organization and citizen. They have right to send the proposals to the responsible government bodies concerning environmental issues of implementation planned activities; to receive information on results of conducted state ecological expertise from relevant responsible bodies. The materials reflecting the public expertise delivered to tСО ОбpОrts‘ МommТssТon sСouХН bО taФОn Тnto МonsТНОratТon unНОr prОparatТon oП МonМХusТon oП state ecological expertise and decision making on realization of expertise object. The public ecological expertise is carried out under the state registration of application of public organization. The registration can be done by local executive authorities (for 7 days) in place where the expertise activities are planned. The public organizations which are organizing this expertise, should inform the population of initiation of expertise and then on its results.

68. The legal and regulatory system for the EIAs also include:

Procedure of Environmental Impact Assessment (adopted by the Resolution of the Government of the Republic of Tajikistan No. 532 as of 01.11.2018).

Procedure to implement State Ecological Expertise (approved by the Resolution of the Government of the Republic of Tajikistan No. 697 as of December 3, 2012).

1 State Ecological Review which is also commonly referred as State Environmental Review means the process only.


_____________________________________________________________________________


Guidelines on the composition and order of development of content and structure of the documentation to be submitted for review (SEE), as well as coordination and approval of all projected budget or investment estimations, design drawings or documentation that must be developed in coordination with the SEE2, buildings and structures and EIA chapters, Strategic Environmental Assessment SEA and feasibility documents; and

List of objects and types of activity for which preparation of documentation on Environment Impact Assessment is mandatory (adopted by the Resolution of the Government of the Republic of Tajikistan No. 253 as of June 3, 2013).

69. The elaborated existing normative legal base is intended for determination of legal basis for implementation of projects and their compliance with state requirements for environmental protection and mitigation of environmental impact.

70. In the Republic of Tajikistan, the organizations with most responsibility for environmental monitoring and management currently are the Committee for Environmental Protection (CEP) under the Government of the Republic of Tajikistan (GoT), the Sanitary Inspectorate of the Ministry of Health, the Inspectorate for Industrial Safety and the Mining Inspectorate. An environmental licensing system exists in relation to handling hazardous waste and mineral extraction. An environmental permitting system regulates the use of natural resources.

71. The Environmental Protection Law states that a SEE should be conducted by the CEP, which is designated as a duly authorized state environmental protection body. The CEP has a comprehensive mandate that includes policy formulation and inspection duties. The CEP has divisions at oblast (region), city and rayon (district) level, in the form of Departments of Environmental Protection (DEPs), within the Hukumat (local administration) at each city or rayon.

4.2 Public Participation

72. Article 12 of the Environment Protection Law proclaims the right of citizens to live in a favorable environment and to be protected from negative environmental impacts. Citizens also have the right to environmental information (Article 13), as well as to participate in developing, adopting, and implementing decisions related to environmental impacts (Article 13). The latter is assured by public discussion of drafts of environmentally important decisions and public ecological reviews. Public representative bodies have an obligation to take into consideration МТtТгОns‘ МommОnts anН suggestions.

4.3 Licenses

73. Licenses are legal instruments to regulate certain potentially hazardous activities where minimal qualifications and strict adherence to rules are required to ensure that they are carried out efficiently, safely and do not result in potentially very significant and irreparable damage to the environment and human health .In particular, licenses are required for handling hazardous

coordination with the SEE.


_____________________________________________________________________________


waste; for activities in industrial safety, sources of ionizing radiation, production and handling of pesticides and other agrochemicals. They are issued by the relevant industry regulator (ministry or committee) or an entity to which it has delegated such right. Licensing is also used to ensure the most efficient and sustainable use of natural resources. For example, licenses are required for prospecting, collecting or extracting mineral resources (borrow areas), or for constructing underground facilities not related to mining.

4.4 Environmental Permits

74. Permits are meant to ensure the sustainable use of natural resources. There are two types of permits: (a) permits to use natural resources; and, (b) permits for emissions or discharges. The natural resources use permits allow their holders to take a certain number or amount of a particular natural resource within a defined territory and time period. They are issued both to individuals (e.g. to hunt a particular species of animal or harvest particular factories) and to organizations (e.g. permits to extract ground or surface water for a particular use). By law, permits are needed for any commercial use of any resource. The authority that issues the permit and the legislation (government resolution) that applies depend on the resource. Permits to discharge polluted matter are issued by the relevant inspectorate (e.g. previous State Water Inspectorate or State Air Inspectorate – now departments) of the local state environmental protection committees to industrial or agricultural enterprises and municipal utilities that release by-products into the environment. The permits allow releasing a certain amount of polluted matter (gases, liquids, solid waste) into the environment. The permits are normally granted for one year and indicate the maximum allowed concentration of the pollutants in the released matter, the maximum volume of the polluted matter and the pollutants allowed.

4.5 State Environmental Program 2009-2019

75. The Program, approved in 2009, obligates ministries and offices, heads of administrations and mayors of cities to improve environmental conditions and ensure sustainable development of the country during the period of economic transition. It calls for adoption of modern environmental standards for water, air, soil, solid waste, toxic wastes, and noise control, based on maximum permissible amounts. Standards are to be supplemented by discharge permits. The Program is accompanied by broad ecological zoning, dividing the country into ten zones (Syr-Darya, Northern Turkestan, Zeravshan, Gissar, Vaksh, Dangarin, Khulbak-Kulyak-Tchube, Karategin-Baldjuvan-Shurobad, Garm-Muksu-Balandkiik, and Badakhshan).

76. The principal directions of the Program are improvement of (i) the environmental status of agricultural lands, (ii) state of water resources, (iii) vegetation including forest resources, (iv) fauna and flora, (v) recreational possibilities, (vi) air quality, (vii) utilization of mineral resources, (viii) public health, and (ix) environmental performance of industry and construction. The Program calls for economic and other analyses of environmental problems and economic mechanisms that are to be used for the purpose of environmental management including: (a) limits on the use of resources, (b) payment for use of natural resources, and (c) pollution charges. Any use of a natural resource – including the assimilative capacity of air, water, and soil – is to be paid for in an amount as determined by the Government. The program calls also for better monitoring,


_____________________________________________________________________________


improved environmental impact assessment, and improved financing of environmental activities. There are section dealing with environmental education, information, environmental centers and environmental legislation. State natural sanctuaries and natural reserves for perpetuation of rare and threatened species are to receive special attention.

4.6 Implementation and compliance

77. A number of legal acts establish liability for violations of environmental laws, which can be enforced by several State bodies. In particular, the 2010 Code of Administrative Violations establishes administrative liability for organizations, their officers and individuals for a range of violations, from the careless treatment of land to violation of the rules for water use or water protection or failure to comply with a State ecological expertise. The administrative sanctions for environment related violations can be imposed by the administrative commissions of Hukumats, Мourts, tСО ωEP’s ТnspОМtors, tСО VОtОrТnarв InspОМtors oП tСО εТnТstrв oП AРrТМuХturО, anН tСО StatО Committee for Land Administration, Mapping and Geodezy. The most common administrative sanction is a fine of up to 10 minimal monthly salaries for individuals and up to 15 minimal salaries to officers of organizations. The 1998 Criminal Code covers crimes against ecological safety and the environment, such as violations of ecological safety at work, poaching, and spoiling land, violation of rules for the protection and use of underground resources. The maximum fine is up to 2,000 minimal monthly salaries and the maximum sentence is up to eight years in prison.

5. Environmental norms and standards

78. Norms are set for air and water pollution, noise, vibration, magnetic fields and other physical factors, as well as residual traces of chemicals and biologically harmful microbes in food. The exceeding of their thresholds results in administrative action, including financial sanctions. Several ministries determine environmental quality standards, each in its field of responsibility. For example, admissible levels of noise, vibration, magnetic fields and other physical factors have been set by the Ministry of Health.

79. Environmental quality standards in Tajikistan are based on GOST, SNiP and SanPiN. GOST (TaУТФТμ ӣ) rОПОrs to a sОt oП tОМСnТМaХ stanНarНs maТntaТnОН bв tСО Euro-Asian Council for Standardization, Metrology and Certification (EASC), a regional standards organization operating under the auspices of the Commonwealth of Independent States (CIS).

6. Noise, Water and Air Quality Standards

81. Tajikistan has standards for permissible noise levels, air quality and water quality. These standards are provided by tables 3, 4, and 5. In addition the standards are compared with international guidelines and standards.

82. The ADB Environmental Safeguards also require comparison with appropriate international standards, such as World Bank Group, World Health Organization etc. For the current project comparison has been made with relevant international standards as shown in Table 2, Table 3, Table 4 and Table 5. The ADB require that the most stringent standard is used.

84. The Environmental Safeguards can be considered to use the term environment in a broad sense. The Policy states, inter alia that an assessment shall be conducted to identify direct, indirect, cumulative and induced impacts and risks to physical, biological, socioeconomic (including impacts on livelihood through environmental media, health and safety, vulnerable groups and gender issues) and physical cultural resources in the context of the projects area of influence.

85. The Policy then goes onto list the Safeguard Requirements for Environment, focusing on:

Biodiversity Conservation and Sustainable Natural Resources Management;

Pollution Prevention and Abatement;

Health and Safety - worker and community

Physical Cultural Resources (Archaeology etc.); and

the Grievance Redress Mechanism (GRM)

86. These issues are addressed in this IEE. The impact assessment scope is presented in Section III.


_____________________________________________________________________________


III. SCOPE OF ASSESSMENT

1. Preamble

87. One of the most important stages of an impact assessment process is the Scoping Stage. Scoping provides the terms of reference of the impact assessment process and enables the impact assessment process to focus on those aspects of the environment which may be significantly affected by the project and its activities. The following sections provide an overview of the scope of the current impact assessment.

2. Physical Scope

88. The physical scope of the Impact Assessment defines the project extent. In general terms good practice for Impact Assessment would expect all elements which are directly related to the project; and any other elements which are either a consequence of the project or which the project relies upon will be included in the Impact Assessment process. The physical scope will include all temporary facilities required for the development of the project, including any manpower camps, laydown areas, fabrication facilities, batching plants and access roads (temporary or permanent).

3. Spatial Scope

89. The spatial scope is the area which is included within consideration of the Impact Assessment process as the Area of Influence. Spatial scope will vary depending upon the topic being studied, for example air quality assessments may extend considerable distances from the project site/s, whilst terrestrial ecology may be a much tighter bounded spatial scope. Similarly, secondary impacts such as health issues will have varying spatial scopes.

4. Temporal Scope

90. The Impact Assessment scope for the Kungurt to Khovaling Road Junction project will include all phases of the project. These will be site clearance, construction, commissioning and testing, operation and maintenance.

5. Technical Scope

91. A key part of the scoping process is ensuring that the Impact Assessment process is focused on those issues which matter, that is impacts created by the project which when acting on a receptor may have significant effects, either through the magnitude of impact or the sensitivity of the receptor (or a combination of these and other factors). The following section provide a rationale for the inclusion or exclusion of topics within the current impact assessment. The text provides a brief overview of the conditions at the site pertaining to the topic being discussed, determination of potential impacts and their significance and if the topic is scoped into or out of the full impact assessment process.


_____________________________________________________________________________


5.1 Agriculture

92. Existing Conditions – the alignment of the road travels through a predominantly agricultural landscape, with much of the land in arable production, with some small areas of orchard and permanent pasture.

93. Potential Impacts – during the operational phase no significant adverse effects are predicted on agricultural resources. There may be marginal benefit to local people who are working the land in improving access to their fields and markets through improvement of the road condition.

94. During the construction phase there are a number of potential impacts which could occur, such as dust soiling of crops, especially fruit crops, changes in hydrological regimes and accidental encroachment of construction equipment and staff onto agricultural land causing loss of crop production.

95. Scope Decision – this topic is scoped into the overall assessment for the construction phase only.

5.2 Air Quality

96. Existing Conditions – The project is in a rural location and the existing road has limited vehicle movements along the route. Traffic counts show that an average of 496 to 506 movements per day. Due to limitations on weight and width of the bridges, and the condition of the road, use of the route by heavy vehicles is very limited.

97. Air quality within the project location is unlikely to be affected by significant sources of pollutants from local emission sources. Local emissions will be limited to vehicle movements along the route, agricultural activities and the burning of solid fuels for heating and cooking in local properties.

98. The local airshed is considered to be unsaturated. Further to note that, air quality survey was conducted on 08 of December 2018 as part of establishing baseline condition of the project route including the Bridges No. 5 and 6. Based on the results of instrumental measurements of ambient air, it is concluded that, the parameters such as, total suspended particulates (TSP), carbon monoxide (CO), nitrogen dioxide (NO2), sulphur dioxide (SO2), are below the Tajikistan air quality standards (Detailed in APPENDIX- F: AIR QUALITY SURVEY)

99. Potential Impacts – During the operational phase there will be limited increases in traffic flows – estimated to be 3% per annum, resulting in an extra 15 vehicle movements per day year on year. To give a total increase by year 2034 (opening plus 15 years) of 290 vehicle movements per day. Additional traffic flows will result in additional increases of emissions of pollutants from the burning of fossil-based fuels as part of cumulative impacts.

100. During the construction phase there are a number of potential impacts which could occur. These include localized changes in the air quality parameters due to the operation of mobile and stationary equipment. The main risk will however, be the emission of fugitive dust, including particulate matter less than ten microns in diameter, referred to as PM10. These emissions can


_____________________________________________________________________________


give rise to soiling impacts of crops and local houses, cars etc., and PM10 and smaller particles are known to affect human health.

101. Scope Decision – For operations, it is considered that the increases in traffic flows on the route, will not give rise to significant changes in the local airshed. For construction there remain possible impacts from local emissions of pollutants from equipment and machinery and fugitive emissions of dust. Therefore, this topic is scoped into the full assessment process only for the construction phase.

5.3 Archaeology and Cultural Heritage

102. Existing Conditions – Tajikistan has a rich archaeological resource throughout the country. For the current project the national database of known archaeological resources was consulted. This showed that there are no known extant registered archaeological sites within area of influence of the project. The adjacent land use of predominantly agricultural land also means that, and surface attributes such as grave mounds will have been removed or damaged by regular ploughing and working of the soils. Within the road corridor, excavations for the original road construction will probably have removed any archaeological resource.

103. Potential Impacts – In theory any excavations could encounter previously unknown archeological resources. For the current project which will involve limited excavations within the already disturbed area of the right of way, it is considered that the risk of encountering archaeological resources is very low.

104. Scope Decision – On the above basis this topic is scoped out of the full assessment process. A monitoring program via a chance finds protocol will be established for this topic (APPENDIX- G: ARCHAEOLOGICAL CHANCE FIND PROCEDURE provide guidance on chance find procedure).

5.4 Biodiversity and Ecosystem Functioning

105. Existing Conditions – The major land use is arable production with some permanent pasture and hard fruit production. Such land tends to have reduced intrinsic ecological value. Such areas are classed as Modified habitat within the context of ADB SPS (2009). There are no significant areas of natural habitats within the project area. The water courses at the project crossing points exhibit a high degree of anthropogenic disturbance. Active removal of boulders and substrates was observed during a site visit conducted in May 2018.

106. The rivers are reported to have very low flows during summer periods and on some occasions surface flow is absent. The development of stable ecological aquatic and wetland communities in these conditions is difficult. Key species like fish will need to migrate up and down the water courses to find areas of suitable water.

107. It is not considered that there are any areas of critical habitat present within the project area of influence.

108. Animals within the road alignment will be limited to common species, either human commensals within the settlement areas, or species suited to agricultural areas in the open


_____________________________________________________________________________


sections of the route. Discussions with local ecologists and the Tajikistan National Centre for Biodiversity indicate that the risk of encountering species of interest, either Tajikistan or IUCN red book species for example, is low.

109. Potential Impacts – The project will directly affect existing road verge vegetation. The project proponents have stated that while some scrub may need to be cleared for the work, no trees will be cleared due to the rehabilitation project. The project is for a rehabilitation of the existing road so now new issues of gene pool restrictions, habitat severance and fragmentation will occur.

110. Scope Decision – This topic is scoped out of the full impact assessment for the operational stages. It is possible for careless construction methods and waste management to affect local ecosystems, especially the water courses and so for construction this topic is scoped into the assessment process.

5.5 Community

111. Existing Conditions – The route runs through a small number of settlements and provides an important link to a number of communities which are located just off the project alignment. Settlements have the usual array of community facilities available in the form of shops. Alongside the route there are no schools, these being located in the larger settlements and away from the road. Similarly, only once pace of workshop was noted during site visits within 50 m of the road alignment. The poor road condition currently limits movements between settlements and further afield.

112. Potential Impacts – The project has the potential to affect community safety during the construction phase of the project, due to increased movements of heavy vehicles along the route. During construction, it is likely that temporary closure of some sections of the route will be required. In particular at Bridges 5 diversion road will be constructed, and existing Bridge 6 will be used as diversion mode of traffic flow. The new location of Bridge 6 is skewed adjacent to its original place (detailed in Project Description Section).

113. During operations new community impacts are not anticipated. Traffic flows on the route will not rise to a level which would cause severance of communities and significantly increased risks to pedestrian users of the road.

114. Scope Decision – This topic is scoped out of the full impact assessment for the operational stages. It is scoped into the assessment for the construction phase of the project.

5.6 Contamination

115. Existing Conditions – During a May 2018 site visit, a Phase 1 Type Contamination Survey was conducted. This entailed making observation of potential contaminated soils (such as staining, stressed vegetation) and current and historic land uses which may present a risk of contamination of soils and ground water. The site survey indicated limited areas of localized contamination, mainly where residents were dumping ash from the domestic fires within garden edges. None of these areas were observed within the working area of the project.


_____________________________________________________________________________


116. To the east of Sarimazor, some 3 km along the river bed, there is a small oil and gas extraction facility. The road at Bridge No 6 is approximately 600 m from this facility. Consultation between the MoT PIU and the Ministry of Energy and Water Resources in May 2018, indicates that the facility is not currently producing gas but intermittently producing oil. This is exported via small diameter (125 mm) pipelines that run parallel to the road in some sections and cross under the road. Within the area of the facility and the oil pipeline there is a risk of historical contamination.

117. Potential Impacts – The project has the potential to mobilize existing contamination and create new contamination. Construction activities, and in particular storage of hydrocarbons such as fuels and oils and poor waste management practices, can lead to contamination of the environment. Depending upon the location and time of the year of an incident, contamination may spread over a wide area, for example releases of hydrocarbon into a river course when it is flowing.

118. During operations hydrocarbon and rubber residue from traffic on the road surface and other solids will be washed into the drainage system and local water courses. It is considered that the level of traffic on the road will not lead to significant contamination issues during the operational phase of the project.

119. Scope Decision – This topic is scoped out of the full impact assessment for the operational stages. It is possible for careless construction methods and waste management to affect local ecosystems, especially the water courses and so for construction this topic is scoped into the assessment process. It is also possible that accidental damage to the oil pipe may occur during construction. Therefore, this topic has been scoped in for the construction stage as far as ensuring adequate measures are in place to manage risk of accidental loss of containment of contaminants.

5.7 Landscape and Visual

120. Existing Conditions – The project area is within the low mountain areas of Tajikistan. There are no national designations for landscape within the projects area of influence. There are limited scenic views from the route, generally limited to areas where the road opens out into the wider flood plains.

121. Potential Impacts – The use of gabion walls as retaining walls will cause localized changes in views into the road. The road already exists and so no new impacts on landscape character are anticipated.

122. Scope Decision – Due to the limited nature of the works and the absence of specific public view points into and out of the project area and no designations, this topic is scoped out of the full impact assessment.

5.8 Material Resources

123. Existing Conditions – The project currently has no demand for material resources.

124. Potential Impacts – The construction of the project will require quantities of various construction materials, primarily aggregates, concrete, steel and asphalt. Based on recent road


_____________________________________________________________________________


projects the local market has adequate capacity to supply most of these materials for the current project without unduly affecting the local supply of such materials for other users. The bitumen for the asphalt will be imported, most likely from Kazakhstan. The operational stage will not create a large demand on material resources, with maintenance being mainly limited to future resurfacing of the wearing course.

125. Scope Decision – No significant effects on local or international markets for the material resources are anticipated due to the project, accordingly this topic is scoped out of the full impact assessment.

5.9 Noise and Vibration

126. The noise level is important for new major road, bridge and other infrastructure projects where heavy construction takes place over a lengthy period of time. The Kangurt-Baljuvon-IVKR rehabilitation and reconstruction works and further maintenance generally require the use of different equipment and machinery, these activities are intermittent and localized, and they nevertheless contribute amounts of sustained noise during equipment operation. However, this project runs over rural areas in Khatlon Province. During the construction phase, the noise level increases and it will be higher than the admissible level at 445 buildings during the day . Likewise, vibration induced by the piling of new bridges or construction noise can have a detrimental effect. This is of particular concern in the case of cultural heritage sites, which may have been standing for many centuries, but which were not designed to withstand such vibration. In case of this project, no such heritage sites are located even in project influence area, there are no structures standing near the road.

127. These issues were discussed at public consultation meeting held at Baljuvon Town on 16th November 2018, where participants expressed these are not a concern for the people including reconstruction of Bridges (APPENDIX- H: PUBLIC CONSULTATION FOR BRIDGES NO. 5 & 6).

128. Further to note that, noise level baseline data has been gathered on representative project sites covering the bridges on 17 and19 of April 2019. During operation there are no sensitive zones or potential problems identified, in scope of the project Noise Measurement and Modeling Plan was prepared (see Annex I).

129. Scope Decision – This aspect has been scoped in during construction as well as operation phases.

5.10 Soils

130. Existing Conditions – The project area has deep loamy soils which, coupled with high rainfall provide good conditions for agricultural production, either arable or permanent pasture for grazing. However, observations during site visits indicated that the soils are prone to erosion die to water flow across the surface. Traditionally the soils would have been protected and bound by the covering grass sward, but arable activities expose the soils and create instability.

131. Potential Impacts – The Project will involve clearance of some road verge vegetation during construction works. This has the possibility of causing instability of soils during rainy periods. During operations, no significant effects on soil as a resource are anticipated.


_____________________________________________________________________________


132. Scope Decision – This topic is scoped in for the construction phase but scoped out of the full assessment for the operational phase of the project.

5.11 Traffic and Transport

133. Existing Conditions – the current condition of the road is poor and restricts travel along the route, increases journey times and has lower safety due to vehicles travelling on the wrong side of the road to avoid pot holes etc.

134. Potential Impacts – The road rehabilitation will, as noted in the need for the project, decrease journey times, reduce wear and tear on vehicles, improve safety and provide improved opportunities to local residents for accessing wider markets and social facilities.

135. The construction phase of the project will result in increased vehicle movements within the area of influence and in particular heavy vehicles which currently make up a small percentage of total movements on the route. As previously noted, works along the route will create increases in journey time during construction activities and in some locations, Bridge No 5 will require temporary service road. As mentioned, the existing Bridge No. 6 will be used as service accessibility during construction period, the new Bridge will be constructed beside the existing Bridge.

136. Scope Decision – The impacts of the increased construction traffic, no temporary road closures will be required.

5.12 Water Resources

137. Existing Conditions – The project area receives high levels of rainfall throughout much of the year. Agricultural production does not rely on irrigation within the project area of influence. Water supply for local settlements is reported to be from spring fed waters, and observations suggest these are often through community stand pipe arrangements. Site visit observations suggested that some people were also collecting river water for domestic use.

138. The project crosses a number of water courses and flood plains along the route. These are prone to flash flooding from rainfall in the upper mountains and foothill. During summer months’ water levels drop and in some cases are reported to be more or less absent. Water flows in spring are also influenced by snow melts in the higher ground.

139. Further to record, water sampling and chemical analysis were performed from 9 sites throughout the route on 08 December 2018. The results of instrumental measurements and chemical analysis of water sampling concluded that, the parameters such as, Weighted substances, mg/l; Dissolved oxygen, mg/l; Oil products, mg/l; Conductivity, m /cm; Coli - index, pcs; BOD5, mg/l; Turbidity are below the Tajikistan water quality standards. The temperature of water samples varied between 6.6 and 9.6. The weather was cloudy (Detailed in APPENDIX- J: WATER QUALITY SURVEY)

140. Potential Impacts – The project has the potential, during the construction phase, to affect water quality through spills of hydrocarbons and other polluting substances. During operations the traffic generated pollution is considered to be minor and with weight and width restrictions on


_____________________________________________________________________________


the route, the presence of large road tankers will be limited. Therefore, the risk of contaminating spills following traffic accidents is considered to be very low.

141. The project will not require large volumes of water for the construction phase, so water use is not considered to give rise to significant effects.

142. Scope Decision – Impacts on water resources are not considered significant so this aspect is scoped out of the full impact assessment. Potential impacts on water quality for the construction phase are scoped into the full impact assessment process.

5.13 Waste Management

143. Existing Conditions –Waste management from local settlements is managed by the local authorities. The removal of household waste will be carried out regularly. Following agreement with the local environmental protection of the Baljuvon District, removal of construction waste, old asphalt and soil will be disposed at the designated sections (km 23, km 25). Wastes will be carried out by good cars that are equipped with drop sides with tarpaulin covering.

144. Potential Impacts – The construction phase of the project will generate wastes, the largest volume of which is likely to be the old asphalt and unusable excavated materials. Improper disposal of wastes can lead to a range of environmental and social effects covering health and safety, visual, contamination etc.

145. During the operational phase no significant impacts are anticipated.

146. Scope Decision – The effective management of waste is a key aspect of the project during the construction phase of the project. Development of controls and management processes will be a feature of the Environmental Management Plan. This topic is therefore scoped into the full impact assessment process for construction activities only.

IV. DESCRIPTION OF THE ENVIRONMENT

1. Preamble

149. This section provides an overview of the existing environmental and social conditions within the location of the proposed project and commensurate with the likely effects of the project on environmental and social receptors.

150. Where specialist topics have been scoped into the full impact assessment process, any detailed baseline data used in the assessment is presented within that specialist section.

2. Project Location

151. The project is located in the Khatlon region of Tajikistan, some 75 km in a direct line from the capital Dushanbe. The location within the country is shown in Figure 1: Project Context within Tajikistan.

Figure 1: Project Context within Tajikistan

Source: United Nations Mapping

152. The project route alignment is shown in Figure 2. It can be seen that the road has a west to east orientation.


_____________________________________________________________________________


Figure 2: Project area

3. General Site Description

153. The project is located in a rural setting with a predominant land use for agriculture, either as managed grasslands for grazing of animals (sheep and cattle), orchards with fruit and nut trees and arable land. In the higher areas of land, the pasture has an upper storey consisting of wild fruit and nut trees.

154. The route alignment is within low mountains and valleys which are intersected by often water courses which are often highly braided in nature and in some instances located within very wide flood plains. Photo 1 provides examples of these river features.

155. Areas of urbanization along the route are few and generally small in nature. Areas of habitation are shown in Figure 3. Many of the villages and clusters of houses are set back from the existing road. Notable areas of habitation include Kangurt, Baljuvon, Sarimazor and Shagmon (see Figure 3).

4. Land Use along Route Alignment

156. A general description of the route follows, distances are approximate and based on chainage for the project starting at 0.0 km at Kangurt.

157. Km 0 to 1.6 km – The road commences at an approximate elevation of 870 m above sea level (asl) and passes to the edge of the village of Kangurt. Within this first 1.6 km the road crosses three bridges as shown in Figure 4.


_____________________________________________________________________________

158. Structures fronting the existing road are a mix of commercial and residential properties. The latter are of generally single storey buildings, and often formed from animal housing/storage areas alongside the road with dwelling areas further back within a courtyard area. Photo 2 shows typical views of this section of the route.


_____________________________________________________________________________


Photo 2: Typical Views of Structures in Kangurt

159. Km 1.6 to Km 11.6 – On leaving Kangurt the route alignment rises steadily to reach an approximate elevation of 1210 m asl at 11.6 km. The route runs through agricultural land which is arable in nature, supporting crops such as cereals and oil seed rape. In some locations the original road construction has cut through low hills and exposed soil walls which have not vegetated over the intervening period. This section has limited tree cover, being restricted to small trees within the route alignment right of way.

160. Km 11.6 to Km 15.5 – at approximately the route alignment passes through an area of open pasture with scattered tree cover (wild fruit and nut trees) before descending to the village of Khanabad. Alongside the route are a small number of properties with the main part of the village lying to the south of the road alignment at a distance of about 100 m and screened by woodland. This area lies below the elevation of the road. The houses nearest to the route sit above the road elevation.

161. Km 15.5 to Km 20 – The route continues to descend before reach a low point of 870 m at approximately 16.4 m. From this point through to KM 20 the adjacent land use is again dominated by arable crop production. There are a limited number of residential properties along this section.

162. Km 20 to Km 21 – at this section the route passes through an area of orchard with cherry, apple and nut trees present.


_____________________________________________________________________________


163. Km 21 to Km 23 – this section of the alignment takes the road through the small town of Baljuvon, crossing bridge no 4 (see Figure 5) before reaching the edge of a major flood plain at Km 23.

Figure 5: Location of Bridges 4, 5 and 6

Source: Google Earth Base

164. Km 23 to Km 25 – at this section the route crosses a river which is flowing from north to south, at Bridge No 5 (see Figure 5), before running along the edge of a river flowing from the east to create a confluence. This section of the route is badly eroded, and no real trace of the original road is visible, the route running within the dry river bed section. The route crosses this east west water course at Bridge 6 (see Figure 5) before starting to ascend. As can be seen in Figure 5, the flood plan to the south of the confluence of the two rivers is very broad,

165. Km 25 to Km 35 – The route ascends from the flood plain, passing through a mosaic of land use, with areas of arable production interspersed with grassland with wild fruit and nut trees.

166. Km 35 to Km 38 – The route continues to rise with a notable increase in tree cover within this section. These are predominantly wild fruit and nut trees.

167. Km 38 – Km 43 – The road rises to the small village of Shagmon, which mainly consists of small agricultural units surrounded by open land and orchards, mainly to the south of the road alignment. The final section of the route passes through arable land before joining with the existing Khovaling road.

5. Topography

168. Tajikistan is a mountainous country as can be seen on Figure 6. The approximate centre of the project is shown by the star symbol. It can be seen that the project lies between the lower plains in the south west of Tajikistan and the higher ground to the north and east.

172. Figure 9 shows that the rainfall can occur throughout most of the year but with significant quantities from September through to May.

7. Land Use

173. As set out in the general description the current land use adjacent to the road alignment is for agricultural production with some areas of human settlement. The agricultural production is centred on arable production. Crops observed to be present and likely to be grown include cereals and oil seed rape.

174. In some locations formal orchards of fruit trees are present. These were a mix of cherry and apple trees. In higher locations the agricultural land consists of pasture for grazing of sheep and cattle.

175. In many of these locations small wild fruit trees and thorn trees are present.

176. Historic land use will also have been agricultural based, perhaps with less emphasis on larger scale arable production and more pasture.

177. In terms of sensitive receptors there are no schools close to the road alignment. In the village of Sarimazor, there is a mosque situated at a distance of 50 m from the road alignment and shielded from the road by a commercial building.

178. Immediately adjacent to this mosque is a Mausoleum to Shohnemotulloi Vali, a religious man from this area reported to be a direct (19th Generation) descendent of the Prophet Mohammad. This mausoleum is set amongst a dense stand of trees. The mausoleum itself is some 100 m from the road, other sitting and small sheltered sitting areas are also present within the wooded area.

179. A listing of potentially sensitive receptors was previously shown in Figure 3.

8. Soils

180. The Project corridor and its surroundings exhibit soil profiles characterized by typically loess, loamy sands and loamy soils, occasionally bench gravel upper Quaternary age, classically formed through deposition of light and typical grey earth, brown carbonate soils. Limitation - erosion, low content of organic in soils and drought in summer period. Soils in other areas are formed through wind deposition over arid or semi-arid areas. The humus layer of the loess and loamy sands is fairly fertile, and agriculture as noted by the extensive cultivation of the Obi Mazor, Surkhob, Vakhs and Yakhsu rivers floodplain. For these soils to be included into agricultural use they require irrigation and the use of mineral fertilizers.

9. Hydrology

181. As part of the bridge crossing design for the project, a hydrological study has been conducted for the project area. The results of this study are presented in detail in APPENDIX A. A summary of the findings is provided below.


_____________________________________________________________________________


182. The rivers of Tajikistan are important sources of fresh water for the Aral Sea. The glaciers and permanent snow feed the rivers of the Aral Sea basin with over 13 km3 of water a year. The major rivers are the Syr Darya (total length 2,400 km), which flows for 195 km across the Fergana Valley in the north, the Zaravshan, which runs through central Tajikistan, and the Kafirnigan, Vakhsh and PanУ rТvОrs, aХХ oП аСТМС toРОtСОr НraТn morО tСan tСrОО ПourtСs oП TaУТФТstan’s tОrrТtorв.

183. The Project Road is located within the Panj River Basin (See Figure 10).

184. The annual hydrological cycle of seasonal rivers of Obi Mazor, Obi-Shirin River, Obi-Khingal and other streams within the Project area formed within the region distinctly divides into two periods: spring-summer high water and low water. It is very difficult to delineate the periods of floods and high water for Mountain Rivers because during spring-summer rains simultaneously melting of snow cover also increases. Over the period of high water, from 70 to 90 percent of annual water volumes flow down through these rivers.

Figure 10: River Basins of Tajikistan9

185. The road follows the valley of the Obimazor River for its first 15 kilometers crossing the river Obimazor at two points and River Kizilsuone once. Water resources in the region are

predominantly used for irrigation and domestic purposes. There are no major hydropower facilities in the Project area. Major water sources within the project areas are shown on Figure 11.

Figure 11: Water sources of project area

186. Groundwater is observed mostly at the depths of 10-20 m. Figure 12 shows the level of the groundwater table for the Project Area.


_____________________________________________________________________________


Figure 12: Groundwater level in Project Area

10. Seismology

187. From the seismological point of view the Project Road corridor is located in 8 point seismic area according to MSK-64 scale10. Figure 13 indicates the locations of the road regularly impacted by landslides and mudslides Vose-Khovaling and associated roads.

10The Medvedev–Sponheuer–Karnik scale, also known as the MSK or MSK-64, is a macroseismic intensity scale used to evaluate the severity of ground shaking on the basis of observed effects in an area of the earthquake occurrence.


_____________________________________________________________________________


Figure 13: Seismic Map of Project Area

11. Biodiversity and Ecosystem Functioning

188. Overview – As noted in the description of land use the road alignment passes through land that is intensively managed, mainly for agricultural production in the form of arable land and permanent pasture. Whilst, inputs of artificial fertilizers, herbicides and pesticides are likely to be limited, the act of regular tilling of the land tends to restrict the habitat value of the area.

189. In parts of the higher land where permanent pasture is present scattered tree cover in the form of wild almond, wild plum and hawthorn (Crataegus spp). In some areas these woody scrub species extend onto the existing road verges.

190. International Ecoregion – The project location is situated within a large Ecoregion, described by WWF as a palearctic mountain ecoregion (https://www.worldwildlife.org/ecoregions/pa0808) which is considered to provide Critical/Endangered habitats for key species. It is note that the majority of this ecoregion comprises the higher mountains to the north and east of Tajikistan.

191. Within the Tajikistan National Biodiversity Strategy and Action Plan, the road alignment is described as being located in a Mid-low mountain semisavanna (savannoid) ecosystem. This ecosystem is stated to be common within southern Tajikistan. A review of the ecosystem map from the NBAP suggests that the road straddles two main ecosystem types as defined by the NBAP. These Mid Mountain Mesophyllic Forest and Mid Mountain Xerophtic Light Forest.

192.

_____________________________________________________________________________


193. Protected Areas – There are not statutorily protected areas at the project site or within 30 km of the project. Some confusion regarding international mapping which appears to be incorrect shows a protected area within the project footprint. Consultation with local officials and the Head of the National Biodiversity of and Biosafety Center (NBBC) for Tajikistan, has officially confirmed the absence of protected areas. A letter confirming this was received from the State Forestry and is presented as APPENDIX B.

194. Existing Conditions – Habitats – The habitats present within the road corridor and surrounding landscape are highly modified. The agricultural activities at the project location are intensive with arable production across much of the route alignment. The excellent growing conditions at this location has made this a favoured farming areas for thousands of years and so the location retains very little, if any natural habitats.

195. The existing road verge comprises a grass sward which is grazed by domestic animals and in many places appeared to be disturbed in nature, being dominated by ruderals species such as Rumex, Malva, and vetches. In locations where the original road has cut through hillocks, the steep faces have not revegetated.

196. On the wider and more open road verges woody vegetation has invaded from adjacent areas. These include hawthorns, almond and wild plum.

197. Existing Conditions – Rivers – The road crosses three different rivers. Each are fed from rain and snow melt. The Head of the NBBC stated that the water courses were sensitive to the effects of climate change due to changing patterns of snow and rainfall. The rivers are spate type water courses with risk of flash flooding following heavy rainfall in the upland areas of the catchment area. In summer low flows are experience. The river beds appear to be suffering from anthropogenic disturbance, with evidence of extraction of gravels and boulders. At Baljuvon, the flood plain is very wide, and the river is braided. True riparian habitats were notable by their relative absence, with few stands of reeds being present.

198. The conspicuous fauna of the water courses is reported to be poor, with a limited number of fish species (See APPENDIX C). These will be feeding on aquatic invertebrates such as stone fly, odonata larvae, etc.

199. Consultation with NBBC suggested that the IUCN near Threated Otter (Lutra lutra) was not native to Tajikistan. The IUCN Red List of species does however, list this species as native to Tajikistan. Local specialists state that this species is absent from the project area. This assumption would be supported by the sporadic nature of river flows and limited food sources for viable populations.

200. Other Fauna – The project area will provide habitat to locally common species, including mammals, birds and reptiles. The area of influence for the project will be limited and for most species the road verge habitat will form only a part of the home range. Consultation with NBBC and local specialists suggest that no rare or uncommon fauna will be at risk of significant adverse effects.

201. Status – Although the project site falls within an ecoregion considered to be endangered, it is clear that local land management has reduced the local habitat value. There are no large areas of natural habitat present.


_____________________________________________________________________________


12. Historical and Archeological Areas of Significance

202. Historic and cultural resources include monuments, structures, works of art, the sites of outstanding universal value from historical, aesthetic, scientific ethnological and/or anthropological points of view, including graveyards and burial sites. The responsibility for preservation, maintenance and assessment of historical and cultural monuments in Tajikistan rests with the Ministry of Culture.

203. Consultations with local authorities in Baljuvon did not report the presence of any historical and archeological areas of significance within the Project areas. However, the region has a rich cultural heritage. Archeologists have found evidence of settlements in the region dating more than 2000 years old, as such the presence of chance finds of items of archeological and historical significance cannot be ruled out.

14 Existing Traffic Flows

207. Traffic counts for the existing road have been conducted on two occasions. The first was in June 2017 and the second in October 2017. The results of the two sets of counts show some high percentage variations. The June 2017 counts did not cover a full 24-hour period and were conducted when an alternative route, the Vos – Khovaling road was still under rehabilitation so there may have been some diverted traffic using the Kangurt to Khovaling Road.

208. On this basis the October 2017 counts are summarized and presented below. Counts were conducted at three locations:

Kangurt (start of project);

Baljuvon (middle of project); and

Intersection of road with Vose – Khovaling Road (end of project).

209. Six-hour counts were conducted at each location over four days and for a different six-hour period each day as shown in Table 8.

210. The results of these counts are presented in Table 9 and Figure 14. Table 9 provides a breakdown of the main motorized vehicles using the road. It can be seen that heavy vehicles are relatively low in number, making up some 6 % of total movements on the route.

211. There is a gradual decline in road use from west to east, indicating that traffic is mainly local and entering the road at Kangurt and stopping at villages along the route.

15 Monitoring

213. A monitoring exercise was carried out to determine the existing baseline conditions of the project area especially in areas surrounding the bridges 5 and 6 of the Roadway. Monitoring for noise, air quality and water quality was carried out for this purpose. Summary of the monitoring results are provided in the following subsections.

15.1 Air Quality Monitoring

214. The air quality survey was conducted as part of establishing baseline condition of the project route including the Bridges No. 5 and 6. Ambient air quality was carried out at seven locations. Pollutants including Total Suspended Particulates (TSP), Carbon monoxide (CO), Nitrogen Dioxide (NO2), and Sulphur Dioxide (SO2) were monitored for this purpose. The results indicate that the concentration values of the above mentioned pollutants are below Tajikistan air quality standards. Detailed monitoring results are provided in Appendix-F.

15.2 Noise Monitoring

215. Noise monitoring was carried out from April 16 to 20, 2019 at two locations. The noise was measured continuously, for 24 hours and the data were taken at every second. Noise monitoring was carried out in village Kangut and Baljuvon. Additional 7-hour noise measurements were done inside an office in village Baljuvon. The monitoring results indicate that the average day time noise levels are within the IFC/WHO guidelines (55dB(A)) at both locations. However, the average nighttime noise value at one of the locations is not meeting the above mentioned guidelines (45dB(A)). Detailed noise monitoring results are provided in Appendix I.

15.3 Water Quality Monitoring

216. Water quality monitoring was carried out at 6 locations. Parameters including Dissolved Oxygen; Oil, Conductivity; Coli - index, pcs; BOD5, mg/l; and Turbidity were monitored for this purpose. The results indicate that all the parameters are below the Tajikistan water quality standards. The detailed monitoring results are provided in Appendix-J.

V. DESCRIPTION OF THE PROJECT

1. Preamble

217. This section provides an overview of the project. This is not intended to be a full technical description of the road construction specifications but aims to provide an adequate level of information on project design and construction activities which may affect the receiving environment.

218. In brief the project allows for the rehabilitation of an existing two lane rural road for a distance of 43 km. The existing surface will be removed, sub bases prepared, and a new surface installed. Refurbishment of four existing bridges, and reconstruction of 2 RCC bridges (replacing metal Bridge No.5 and Bridge No. 6 in to RCC with 2 lanes) are included within the project scope.

219. No land acquisition is required for the project, for the most part there will be no effective widening of the existing carriageway. In a small number of locations and easing of curves will be achieved by minor realignment but not beyond the existing Right of Way of the road.

220. Ancillary works will include drainage improvements and signage. No street lighting is proposed within the project scope. The road is classed as a Category IV route based on the former Soviet standards used in Tajikistan. A summary of the Category IV road parameters is shown in Table 10.

2. Need for the Project

223. The existing road was constructed over 30 years ago, during the Soviet era in Tajikistan. Since then maintenance has been absent or minimal and all of the road surfaces are stressed, and, in many places, the top wearing course has worn away. At Baljuon, the road passes through the river bed and has been completely washed away over the years. Traffic now passes along the dry river bed. Images showing typical condition of the road surface are presented as Photo 3. It can be seen that the road is in various states of degradation. Additional views of the road are presented in APPENDIX D.


_____________________________________________________________________________


Photo 3: Images of Road Condition

224. The Kangurt to Khovaling road intersection passes through and near to a number of small settlements (see Figure 3). The poor road condition makes travel more difficult for the population of these settlements and in turn restricts access to healthcare facilities, markets and outlets for their agricultural produce. The Government of Tajikistan and International agencies have placed considerable store in the development of effective national and international road connections аТtСТn ωОntraХ AsТa as a аaв oП aХХОvТatТnР povОrtв anН ТnМrОasТnР opportunТtв Пor tСО natТon’s population. The rehabilitation of this road will extend the improved network in this area and link the settlements along the route to Dangara to the North West and then onto the capital Dushanbe. To the east the newly rehabilitated route will give the local population access to the recently upgraded Vose to Khovaling Road and Khovaling itself.


_____________________________________________________________________________


225. Without the proposed upgrade the existing road will continue to deteriorate to the point of having very limited accessibility, reducing the local popuХatТons’ access to essential services and limiting economic growth of the area.

3. Future Traffic Flows

226. Predicted increases in traffic movements are 3% per year. The rehabilitation will make the route more accessible to local people and some minor increases in local traffic movements are to be expected. However, there are other key routes available for long distance travel, including from Khovaling to Dangara and then to the capital city, Dushanbe on a newly rehabilitated road. The 3% increase in movements is based on World Bank predictions of a 3% growth in GDP which they state will result in a concomitant 3% increase in traffic flows on the national highway system.

227. Using a compounded 3% growth and a 15-year project life, then traffic movements will increase by some 60% by 2034, giving rise to predicted movements in the range of 780 -800 per day.

4. Summary of Key Construction Tasks to be Undertaken

228. The rehabilitation will have three key tasks which may interface with environmental receptors. These are:

Rehabilitation of the road bed and surface;

Rehabilitation of four river crossings (Bridge No. 1,2,3 & 4) and 27 culverts;

Reconstruction of two river crossings (Bridge No. 5 and Bridge No.6) and

Rehabilitation and improvement of road drainage arrangements.

229. Ancillary works will include the installation of safety features such as barriers, signage and road markings. The existing metal Bridge No. 5 and Bridge No.6 will be reconstructed and widened to RCC Bridges along the given section and no alternative bridge locations are considered except relocation of few meters of Bridge No 6. As such, Bridge No 5 will be located in its original place, and considering the hydrological study Bridge No 6 will be located adjacent to the existing place (Figure 15, 17, 18, and 19).

230. For each of the above key tasks, a summary of activities which may impact environmental receptors is provided in Table 12 to Table 16.

5. Bridges

231. As per initial contract, the metal Bridge No. 5 at km 23+550 and Bridge No. 6 at km 26+000 were supposed to be renovated/ rehabilitated. The existing bridges are too narrow and can allow only one-way traffic. The bearing capacity of the foundation does not allow heavy transport to pass through. It will not be wise to renovate the two existing metal bridges. Therefore, it was propose to construct two new RCC bridges. The calculation of cost is described elaborately item wise. The cost of the Bridge No. 5 with a span of 193m is calculated as US$ 2,219,684.73 and for the bridge No. 6 is US$ 2,067, 019.74. By deducting the amount of renovation of Bridge No.5 the additional cost will be US$ 2,219,684.73-$ 409,243.94=US$ 1,810,440.79. By deducting the amount of renovation of Bridge No.6 the additional cost will be US$ 2,067,019.74-$ 714, 115.84=US$ 1,352,903.90. Considering reduction of quantity in Bill No.5 items of works total amount required for the implementation of this Variation Order no.1 is $3,617,006.09. Due to the reason that there was savings from the Contracts of Vose- Khovaling and Sayron- Karamyk, which is enough to cover this additional cost for the Kangurt-Baljuvon-Khovaling Road project.

232. As noted above the project includes the rehabilitation of four bridges along the route. The location of these was shown in Figure 4 and Figure 5. There are two RCC new bridges (Bridges No.5 and Bridge No.6) to be constructed for the project.

233. Table 17 provides a summary of each bridge in terms of size and construction. Example images for each bridge are presented in Photo 4 and Photo 5. Figure 15 shows the Plan, and Figure 16 the cross section of Bridge No.5 in its existing location. Likewise, Figure 17 displays the plan and Figure 18 shows the cross section of Bridge No.6.

5.1 Activities for Bridge No 5 and Bridge No 6

234. Pre-construction – During this phase the following activities will be undertaken:

Traffic Management Plan – Within 21 days after the commencement date, the Contractor must submit its Traffic Management Plan (TMP) to the Engineer for approval.

Site Specific Environmental Management Plan (SSEMP) - During this period the

Contractor shall be responsible for preparation of his own SSEMP to conform to this IEE and its EMP. The SSEMP shall be completed with 30 days of the signing of the Contract to ensure that all EMP measures are included within the Pre-construction activities. The SSEMP shall be updated on completion of the Pre-construction phase and prior to the start of detailed design and construction when all of the final environmental aspects, such as locations of borrow pits, quarries, construction camps, are known.

Rehabilitation – works include:

The construction of asphalt concrete overlays of the existing approach to the bridges. • Excavation and removal of unstable materials from the bridge site, unstable slopes and

construction of sub-soil drains and earth retaining structures at a limited number of bridge sites.

• The construction of a limited number of retaining structures necessary to stabilize unstable slopes. Such structures include stone masonry walls with cement mortar and gabion retaining walls

235. No other actions, such as tree felling, will occur. Strengthening of the bridge with the additional layer of asphalt is required to address the deterioration of the pavement due to higher than predicted bridge use (specifically by heavy goods vehicles).

5.2 Construction Methodology and Diversion Road

236. Construction methodology would be confirmed by the contractor but it is assumed that the piles would be constructed with a piling rig from the bank without the need for temporary trestles or embankment in the river. The beams would then be lifted into position using a mobile crane and the bridge deck constructed. The deck could be either cast insitu concrete or precast in segments, craned into position and stitched together with concrete pour strips.

237. The alternative to constructing a new structure adjacent to the existing bridge is to construct a temporary bypass road (for Bridge No.5 with box-culvert to pass river water flow) or equivalent alongside the structure. The existing bridge No 5 would then be demolished by an external agency which not yet decided by the client, and a new RCC Bridge as described above reconstructed whilst traffic is diverted to the temporary bypass. The existing Bridge No.6 will be used as bypass because the new RCC Bridge will be constructed adjacent to its original site. This option would not involve the acquisition of land to accommodate a minor road realignment to direct traffic over the temporary structure.


_____________________________________________________________________________


238. Further to describe, the Contractor is responsible for traffic safety and control, including the construction of such temporary road diversions as may be necessary to maintain the flow of traffic during the course of the works, and shall comply with the requirements of the Police and Local Authorities. The Contractor will maintain the existing road and drainage systems within the project limit, where the existing pavement has not been disturbed for construction, free of potholes, to safe and smooth riding conditions and free of overloading.

239. The type of plant likely to be required for replacement works at 2 Bridges (and depending on the construction methodology used by the contractor and which option is implemented) includes:

A piling rig (for construction of piles) Mobile crane (for lifting beams, deck pieces into place) Digger Trucks for carting aggregate Roller (for compaction) Transporters (for precast beams made offsite, etc.) Pump (for extracting water, drainage, etc.). Jackhammer and compressor (for demolition)

240. Further to note, the contractor must submit a construction plan to engineer.

5.3 Traffic for 2 Bridges count

241. A Traffic count has been performed at three locations. e.g. Khovaling check post at Km 23, Baljuvon and Kangurt. The result of traffic count is as follows:

Kangurt to Dangara- 774 vehicles per day. Kangurt to Baljuvon- 898 vehicles per day. Baljuvon to Kangurt - 428 vehicles per day. Baljuvon to Khovaling check post at Km 22 - 496 vehicles per day. Khovaling check post at Km 22 to Baljuvon - 506 vehicles per day. Khovaling check post at Km 22 to Khovaling- 479 vehicles per day.

5.4 Rapid Environmental Assessment

242. The Rapid Environmental Assessment conducted for the project indicates that, there are no sanctuaries, environmentally protected areas, archaeological sites, graveyards located near the bridge project sites and its area of influence. The REA for Bridge No 5 and Bridge No 6 is detailed in APPENDIX- K: RAPID ENVIRONMENTAL ASSESSMENT FOR BRIDGES NO. 5 & 6).

5.5 Basic Construction Tasks to be undertaken

243. The reconstruction of 2 Bridges will have the following key tasks which may interface with environmental receptors. These are:

Reconstruction of the 1.6km approach road bed and surface and exit road of 150m (Bridge


_____________________________________________________________________________


No.6 from Baljuvon side); Reconstruction of two river crossings (bridges no 5 and bridge no 6); and

244. Ancillary works will include the installation of safety features such as barriers, signage and approach road markings.

245. For each of the above key tasks, a summary of activities which may cause induced impact to environmental receptors is provided in Appendix- L, Work Description of Bridge No.6. The following Table 19 provides initial contract for rehabilitation which is not applicable now.

6.1 Quarries & Borrow Pits

246. The exploitation of the borrow pits and quarries will be conducted by licensed companies. The exact locations of suitable borrow sites and quarries are the Obimazor river bed, which will be decided by the Contractor and specified within the SSEMP (Photo below).


_____________________________________________________________________________

7. Land Use around Bridge 5 & 6

247. Bridge No 5: The road from Kangurt entering to Bridge 5 starts through the Baljuvon town (Figure 5), this is the edge of a major stony flood plain of Shurobdaryo River at Km 23. Along the floodplain the hilly areas with terraces continues to the left bank with native vegetation along the hill slopes, the river flowing from north to south. At the approach, there are scattered restaurants, caПé anН ПОа МommОrМТaХ struМturОs. TСО ОбТt Пrom tСО ψrТНРО ОбСТbТts usuaХ smaХХ toаn sМОnarТo with administrative and commercial buildings of 1 or 2 storied in a linear pattern along the road.

248. Bridge 6: After crossing Baljuvon town, the road running along the edge of Obimazor River, the landscape is hilly along the country side with scattered houses on hill slopes. The approach road to the Bridge 6 is badly eroded, vehicles move over the dry stony river bed and floodplain, and no existing embankment exists to trace the original road. In some hill slope locations of Baljuvon village scattered orchards, fruit trees are available. The route crosses water course at Bridge 6 (Figure 5). There are no agricultural, and commercial activities in project influence area, even no natural habitats to support terrestrial flora and fauna along the route and bridge area.

8. Earthworks

249. The Works include the following types of earthworks necessary for the reconstruction of the Project Road and all associated works:

• Excavation and removal of the existing pavement materials and the existing road embankment.

• Construction of subgrade.

• Excavations in cuts.


_____________________________________________________________________________


9. Retaining Structures

250. The following types of earth retaining structures will be used by the Contractor:

• Gabion works for retaining walls, river groins, scour protection and channel lining works.

10. Permanent Ancillary Features

251. The Works include the design and construction of Bus Stops and bus shelters. The Contractor must prepare a detailed design based on the conceptual drawing prepared during the preliminary design. A preliminary schedule of bus stops is provided in the Typical Drawings to the Contractor. However, the exact locations of bus stops will be finalized after the consultations between the Contractor, the Employer and the Engineer, according to the instructions of the Employer.

11. Source of Materials

11.1 Quarries & Borrow Pits

252. The using of the borrow pits and quarries will be conducted by licensed companies. The exact locations of suitable borrow sites and quarries will be determined by the Contractor and specified within the SSEMP. The Project will not use materials from illegal or non licensed quarries.

11.2 Asphalt Plants

253. Tajikistan does not have access to bitumen within its own territory. Therefore, all bitumen will be imported. Based on recent projects within the same location, it is highly likely that the source of bitumen will be Kazakhstan. The Contractor will be responsible sourcing this material and ensuring safe transportation. Similarly, the appointed lead contractor will be responsible for operating the plant and ensuring the facilities comply with the local regulations and EMP requirements. All necessary permits to operate will be obtained from the local authorities including the DEPs.

254. However, the Contractor has to liaise with Local Administration for disposal of construction waste. The Contractor is to use existing Asphalt plant for Kangurt-Baljuvon-Khovaling road, which was used before for construction of Dangara-Kangurt road (not ADB financing) – at km 0+50 of Dangara-Kangurt road. It will be agreed with Contractor that before the use of this Asphalt plant for rehabilitation of Kangurt-Baljuvon-Khovaling road they will clean the area.

11.3 Water

255. Non-potable water will be derived from the Surkhob River. The locations of the extraction points have yet to be determined, although they should be approved by the Engineer and DEP prior to the start of extraction. Potable water will also need to be sourced for construction camps.


_____________________________________________________________________________


11.4 Construction Camps

256. Camp sites will be selected preferably at km 26+000 keeping in view the availability of an adequate area for establishing camp sites, including parking areas for machinery, stores and workshops, access to communication and local markets, and an appropriate distance from sensitive areas in the vicinity. Final locations will be selected by the Contractor after the approval from the DEP and the Engineer (Detailed in Appendix- M, Construction Camp).

11.5 Storage Areas

257. Temporary storage areas will be required for certain activities, such as the storage of construction equipment. The tentative location is at km 26+000.

12 Road Safety

258. The scope of the Permanent Works includes the planning, manufacturing and installation of traffic signs and application of pavement markings along the entire length and for all features of the Project Road. The following types of traffic signs will be installed along the Project Road:

i Warning Signs

ii Regulatory Signs

iii Signs for all off-ramp/adjacent roads

iv Information and Direction Signs

259. In addition, the Works include the construction/manufacturing and installation of different types of safety barriers steel guardrail, kilometer posts and guide posts.

260. The principle road safety benefits the project will deliver are the following:

• Reduced risk of vehicles leaving their lane to avoid potholes and surface deformations;

• Reduced risk of accidents due to road hazards, e.g. flooding of roadway, foreign objects (falling rocks) on roadway;

• Improved sight distances due to improved vegetation control;

• Better separation between pedestrians and vehicles in settlements; and

• Better night driving conditions due to improved carriageway and improved pavement centerline markings.

261. Some of these advantages could be partially offset by the higher speeds which will be possible after the road improvements.


_____________________________________________________________________________


13. Operational Parameters

262. The rehabilitated road will be a Category IV road with two lanes. Likewise, Bridge No. 5 will be reconstructed with two lanes.

263. The design speed limit will 60 kph in non-settlement areas and 40 kph in settlements.

264. The road rehabilitation is anticipated to generate limited induced traffic increases but a value of 3% per annum increase in traffic movements has been allowed for in line with World Bank estimates of increases in Tajikistan Gross Domestic Product (GDP) and parallel increases in the national road network.

14. Analysis of Alternatives

265. The analysis of alternatives is an effective tool to examine the number of options (siting and technology) and establishing most environmentally favorable alternative, or with cause minimum environmental loss to the natural and social environment. For this Kangurt-Baljuvon-IVKR, project alternatives are carefully taken into account in selecting the alternative alignments for the road and the location of Bridge No.6. Further, there are no sensitive environmental issues associated with the existing road corridor (ROW) including all 6 bridges and 27 culverts.

14.1 Route Options

266. As the project is for the rehabilitation of an existing road, alternative alignments for the road have not been considered. Firstly, there are no significant effects of the existing route on receptors and therefore no need to locally realign the route. Secondly, new alignment would introduce new potential environmental effects. Therefore, the best environmental option was to conduct the rehabilitation within the existing right of way.

14.2 Do Nothing Option

267. The do-nothing option would not achieve the desired benefits of the project. Leaving the route to further deteriorate would continue and exacerbate the isolation of communities along the route and eventually make access impossible for many types of vehicles during wet and snow conditions.

268. Without the project, road traffic will continue to increase, it is expected to account for most increases in passenger, and freight transport using the same road routes. The do-nothing option was dismissed on environmental grounds as it would not assist the local population from growing economically.

14.3 Do Minimum Option

269. The do-minimum would consist of limited repairs to the road. This was not considered viable as the road condition has gone beyond the ability to repair on a piecemeal basis. Repairs would be costly and not fully achieve the desired aims of the project. This alternative was dismissed.


_____________________________________________________________________________


14.4 Selected Option

270. The selected option was considered to be the most cost-effective approach to achieve the desired outcomes of improving access and economic opportunity. Budgetary constraints limit the ability to widen the route. However, the rehabilitation of the 43 km road, 27 culverts including reconstruction of 2 RCC Bridges leads to a Category IV standard. For the alignment of Bridge No. 6, the present alignment considered by PIURR was based on the premise that it will reduce erosion of Obimazor river and ensure safer operation.

271. Further, no alternative modes of transport are available in the project area, as such, rehabilitation of existing road and 4 Bridges and culverts, and reconstruction of 2 RCC Bridges will amplify accessibility of regional transport network and road safety.

VI. IMPACT ASSESSMENT, MITIGATION AND MONITORING

1. Preamble

272. This section provides information on the impact assessment methodology and process adopted for the assessment of project impacts and determination of their significance.

273. Development of mitigation measures for identified significant effects are set out, and any residual significant effects are reported.

274. The assessment findings are based on all mitigation measures presented in this document being fully implemented as part of the project implementation. All mitigation established in the report are considered to be committed mitigation once the report has been approved by ADB. The commitments made within the Updated IEE become a binding part of the contract and grant agreement.

275. At the current stage of the development a lead construction contractor has recently been appointed. As many of the potential impacts and scope of work of this project relate to the project construction phase, then consideration placed for the need for an update of the findings of previous IEE of May 2018. This has been made as the contractor is appointed and his working methods, proposals for camps and locally negotiated borrow pits and waste disposal areas have been planned.

276. The mitigation measures provided in this IEE shall be considered as high level in many cases and will need to be refined by the contractor during the development of Site Specific and Topic Specific Environmental Management Plans.

2. Process of determining effects

277. A standardized approach will be based around standard terminology for the determination of impacts and determination of effects, their significance and mitigation or offsetting. The following sections provides an overview of proposed process of impact assessment to be used for the current projects. This section provides the conceptual model to be used for determining effects.

278. The proposed approach for impact identification and assessment of effects relating to air land and water will be based on the Source – Pathway – Receptor – Consequence Model (SPRC). Such an approach is commonly used in contamination studies but is highly applicable for many of the elements considered in an impact assessment process. The model is shown diagrammatically below in Figure 19.


_____________________________________________________________________________


Figure 19 Source Pathway Receptor Model as used in EIA

279. The model shows that to have an effect on a receptor you need all elements of the chain to be present. Therefore, an effect can only occur if there is a source (of change), a receptor upon which that change acts and a pathway between the source and receptor.

280. The SPRC conceptual model is less effective on intangible elements of the environment. These include potential exceedances of legislative standards and topics such where human perceptions and constructs are considered, for example landscape and visual impacts where individual perceptions of beauty, scenic value are important.

281. The SPRC model brings out some important aspects of terminology for the impact assessment process. The first is that the terms impact and effect are not synonymous and cannot be used interchangeably. As can be seen, the IMPACT is the change in environmental variable. The size of change can be determined objectively in cases where change can be measured or predicted, for example increases in emissions to air.

282. This IMPACT acting on the RECEPTOR creates a consequence or EFFECT on that receptor.

283. In order to determine the level or importance of the effects two key aspects need to be determined. These are:

Characterisation of the magnitude and nature of the impact; and Identification of valued Environmental Receptors and their level of importance

and/or sensitivity to change.

284. The following sections provide guidance in determining VER and ascribing value/sensitivity.


_____________________________________________________________________________


3. Identifying Receptors

3.1 Valued Environmental Receptors

285. Based on the SPRC model it is necessary to identify receptors which will be subject to the change in environmental variable.

286. The Valued Environmental Receptors (VER) and its sensitivity to change may not be the same for each discipline. Thus, each discipline needs to НОtОrmТnО Тts oаn sОt oП VER’s anН ascribe values to each of them.

287. Valued Environmental Receptors can be defined as:

Elements of the environment that are of value to the functioning of natural or human systems (i.e. areas or elements of ecological, landscape or heritage value, soil and sediment, air and water bodies); and

Human receptors, such as people (i.e. users of dwellings, places of recreation, places of employment and community facilities), and human systems (e.g. employment market).

288. In addition, receptors will include legislative and policy standards and values. For example, air quality limits, noise standards and planning policy requirements.

289. The VERs are described in terms of their spatial importance and/or the sensitivity of that receptor to change due to potential impacts.

290. The environmental value (or sensitivity) of the receptors identified will be defined using the criteria in Table 20.

Table 20: Value and Sensitivity of Receptors used in the impact assessment

Value / Sensitivity Description of Value

International/ Extremely

Sensitive

High importance and rarity, international scale and

limited potential for substitution (e.g. school or hospital

receptor) Extremely sensitive to change

National/ Highly sensitive High importance and rarity, national scale, and limited

potential for substitution (e.g. residential receptor) – very

sensitive to change

Regional/ Moderately

sensitive

High or medium importance and rarity, regional scale,

limited potential for substitution (e.g. commercial or

recreational receptor) and moderately sensitive to

change

Local/ Low sensitivity Low importance and rarity, local scale and insensitive to

change

4. Characterizing Impacts

292. Size of Impact - As noted above the impact is the change of state of the environment which is caused by a project activity. In general, this change can be measured or estimated in some manner. For example, a change in sound level of 2 dBA, or an increase in ground concentration of an air pollutant of 20 mg/m3. For some topics the measure may be an area of land to be affected or number of trees to be lost etc. Wherever possible the size of the impact should have a physical measurement.

293. Other aspects of an impact - While the size of the change in environmental parameter is an important aspect of an impact, there are other aspects which will determine the severity of the impact when it acts on the receptor.

294. For this impact assessment the following aspects are taken into consideration, in addition to the Size of Impact as set out above:

Extent of impact; Duration of Impact; Frequency of Impact; Probability of Impact Occurring; and Reversibility of Impact.

295. The assessment process used in this impact assessment process will use a bespoke scoring system to enable a systematic and transparent process to be undertaken to determine the impact magnitudes identified.

296. The following sections provide the scoring system to be adopted and its rationale.

297. Extent of Impact or Area of Influence - This relates to the physical extent over which the impact will happen. A larger extent would tend to lead to increased risk of significant effects occurring than a highly localized area of influence. The classification of this variable and the ascribed scores is shown in Table 21

Table 21 Classification of Extent of Impact and Assigned Scores

298. Duration of Impact Effect - An ТmpaМt’s maРnТtuНО аТХХ bО ТnМrОasОН as Тts НuratТon increases. It is important to note that the impact duration is not synonymous with the duration of the event causing the impact. The duration is defined as how long the impact will last. For example, a loss of containment event resulting in a chemical spill may last only 5 minutes but the impacts of the chemical entering the environment will last much longer depending upon the type of chemical, location and nature of spill and any remediation efforts.

299. The classification of this variable and the ascribed scores is shown in Table 22.

300. Frequency - An event, such as blasting during site preparation works, may be short term in nature but if the event is repeated many times during the course of the project then the magnitude of the impact would be considered to be increased. The classification of this variable and the ascribed scores is shown in Table 23.

7

*For one off events, a score of 1 is ascribed if the event does not lead to a permanent non-reversible impact, if the impact is permanent; a score of 5 is used.

301. Probability - Impact assessment for some issues is based on risk assessment. Not all predicted impacts will occur but should be considered in the assessment process. In order to account for this, a three-point probability scale and scores has been used as follows:

Certain 5 High 3 Low 2

302. Reversibility - If an impact can be readily reversed, then its overall magnitude would be considered less if it cannot be rectified. For example, the loss of natural habitats can never be


_____________________________________________________________________________


fully reversed but the visual impact of a wind turbine will be reversed at the end of life when the turbine is dismantled and removed.

303. For this impact assessment process, a simple Yes or No scale is used with associated scores of 1 and 5 respectively.

304. Size of Impact - For the established size of impact the following values have been ascribed:

Low 3 Medium 5 High 8

305. For any impacts which do not exceed the threshold of significance then by definition, the impact severity must be negligible.

306. Overall Impact Magnitude Scoring Model - The scoring model for the described variables results in scores across a range of 7 – 40. The impact assessment uses a four-point terminology to describe impact magnitude. This is presented in Table 24. The model ascribes the outcomes of the scoring of the variables as follows.

7 – 15 Negligible 16 – 23 Minor 24 – 31 Moderate 32 – 40 Major

307. Assessment of Significance - A significant effect may be broadly defined as one which should be brought to the attention of those involved in the decision-making process. The determination of significance of an effect uses a two-dimensional matrix based on the above parameters of Impact magnitude and Value/sensitivity of the receptor.

308. The proposed assessment will use a matrix for determining the significance of an effect as presented in Table 25. Significance is therefore a function of the value or sensitivity of the receptor being considered defined in Table 20 and the consequence of impacts defined in Table 23.

Table 25 Matrix for Determining the Significance of Environmental Impacts

International/ Extreme

National/ High

Regional/ Moderate

Local/Low

Major HIGH HIGH MEDIUM LOW

Moderate HIGH MEDIUM MEDIUM LOW

Minor MEDIUM MEDIUM LOW NS

Negligible NS NS NS NS

309. The impact assessment has utilized the following semantic definitions of the significance terms High, Moderate and Low. They are based on the terminology used in international principles and guidance and on the geographical context of the effect:

High – An environmental effect that has importance at international or national level and is irreversible or unprecedented;

Medium – An environmental effect that has importance at a regional scale and/or one that can be readily reversed with intervention and is limited to the site boundary and immediate surrounding area;

Low - An environmental effect that is only important in a local context, which is readily mitigated, and it occurs only within the boundary of the project; and

NS – An environmental effect that is considered non-significant.


_____________________________________________________________________________


310. Significant adverse effects occur where valuable or sensitive receptors, or numerous receptors, are subject to impacts of considerable magnitude and duration. Some effects will be temporary, others are permanent in nature and these will be stated in the assessment.

5. Mitigation

5.1 Hierarchy of Mitigation

311. Figure 20 shows the Hierarchy of Mitigation as defined by the World Bank Group.

312. This is based on the principle of avoidance of impacts through design, followed by minimizing impacts through mitigation, and finally offsetting impacts that cannot be mitigated fully.

Figure 20 Hierarchy of Mitigation

313. The above hierarchy has been incorporated into the Updated IEE process for the current project. The mitigation set out in this document is committed and will form part of the contract documentation.

6. Results of the Assessment Process

314. The results of the assessment are present in the following sections.

315. A total of twenty Valued Environmental Receptors (VER) were identified during the assessment process. A full listing of these and their ascribed value or sensitivity to change is

316. The total number of impacts identified during the EIA process was twenty-nine, a breakdown of which is provided in the following tables.

317. Table 27 shows the level of significance ascribed to impacts without mitigation broken down by environmental aspect. There were no predicted High impacts, 15 medium impacts, 10 low impacts and 4 which were considered to be non-significant. It can be seen that 7 out of the 28 identified impacts relate to health and safety issues, either community safety or Worker Health and Safety. The other notable area of concern highlighted by the impact assessment process is the potential for contamination of the water courses within the project area.

The table shows that the mitigation measures are predicted to reduce most effects to Non-significant (NS). Only four significant effects remain, two of these are positive effects, one at low significance and one at medium significance. Two low significance effects remain after mitigation and are considered as Residual Significant Effects and are discussed further in the Residual Significant Effects Section.

7. Assessment of Environmental Impacts and Mitigation Measures for

additional works on Bridge No.5 and 6

320. The context for the assessment is that the 2 crossings (Bridge No 5 at Shurobdaryo River and Bridge No 6 at Obimazor River) already exist and environmental impacts would have occurred when they were first constructed. The environment consists of habitat that has been highly modified by the structures, road, agriculture and other land uses and the presence of the hamlet in the surrounding area. The key environmental and social impacts relate to any proposed works that involve the construction of a new or replacement structure and may be either positive or adverse. The repair and maintenance of existing structures and reconstruction of 2 Bridges will have only minor impacts that can be avoided through careful and adequate environmental mitigation measures during construction. In this case the UIEE and EMP covers potential impacts and mitigation measures.

321. The following discussion therefore relates to a consideration of options that involve full replacement or construction of 2 new RCC Bridges. Same impact assessment methodology (as carried out for original IEE study) has been followed to determine the impact significance due to the additional works.

7.1 Design and Pre-construction impacts

7.1.1. Impacts on Physical Resources

322. Physical impacts in the design and pre-construction stage relate to the consideration of climate change and natural hazard impacts, impacts on topography, geology and soils impacts as well as impacts that may arise through the course of the project due to inadequate inclusion of mitigation measures in contract documents and capacity enhancement/training of contractors at the outset of the project.

323. Impacts associated with inadequate inclusion of mitigation measures in contract documents and lack of understanding of environmental issues can be addressed through proper inclusion of the EMP into tender documents (Appendix-O) as well as ensuring the EMP is updated as necessary following the detailed design phase.

324. Mitigation measures include:

325. Specify in tender documentation that the contractor shall engage appropriately qualified and experienced staff to take responsibility for the environmental management and safety issues at the working level and to monitor the effectiveness and review mitigation measures as the project proceeds.

(i) EMP and any conditions of the UIEE, development consent and lease are included in tender documents and mitigation measures appropriately budgeted for.

(ii) The Contractor to submit construction environmental management plan (CEMP) based on contract EMP for approval by Project Management and Construction Supervision Consultant (PMCSC) (i.e., site clearance, site drainage, waste and materials management, traffic, noise and dust management etc.).


_____________________________________________________________________________


326. Natural Hazard Impacts: The Bridge sites and hinterland areas are located within a catchment that has periodic flooding of the watercourses. Indeed, the condition of the crossings is in part due to damage suffered during severe flood events. As both the bridge projects are inland, the most significant natural hazards / climate change consideration is an increase in the frequency of extreme flood events in the future.

327. The structures will need to accommodate stronger and faster water flows, which could be achieved by increasing the height of the water crossings to accommodate increased flood discharges and by having an appropriate design of bridge that will allow for debris movement during flood (and minimize blockage risk).

328. Further to define more site-specific, considering the original Updated IEE, the Shurobdara and Obimazor rivers can be categorized as rainfall-snow rivers as per standard classification. The runoff is generated from rainfall as well as melting of snow. Mitigation measure include (not limited to):

(i) The proposed works will be designed in accordance with the design criteria so as to mitigate the future potential impact of natural hazard/climate change.

329. Topography, Geology and Soils: There are no significant earthworks that would impact on the existing topography, geology and soils of the Bridge sites. Approach to Bridge No 6 from Baljuvon side and exit the bridge, new high level embankments of 2 m high will be constructed. Despite this being a significant amount of earthworks, the topography of the Bridge No 5 and Bridge No 6 crossing area is already gentle to rolling and so the proposed earthworks would ТmprovО tСО tОrraТn, partТМuХarХв Пrom a roaН usОr’s saПОtв pОrspОМtТvО.

330. The embankments associated with crossings would be constructed using material cut from the existing area and so the geology and soils of the project sites would not be altered. No mitigation is considered necessary.

331. Erosion. Structures within a watercourse have the potential to cause scour/erosion by altering the current flows. This is particularly the case around piers and piles which slow the current flow on the upstream side and accelerate it on the downstream side (causing scour). The creeks where the projects are located have a very low flow and slow current speeds when not in flood and so the expected impacts of the replaced structures during these periods is considered to be minimal. During flood conditions, the current speeds increase and correspondingly the scour potential.

332. However, mitigation measures are proposed as follows:

(i) Design structures to allow continued flow of water through.

(ii) Minimize the number of piles in bridge design.

7.1.2. Impacts on Ecological Resources

333. The main ecological impacts that would arise from the design and pre-construction phase relate to designs that would require insignificant vegetation clearance, such as new road and bridge alignments through unmodified areas. The terrestrial ecology in the vicinity of the proposed 2 bridge projects is not characterized by presence of invasive, flora and fauna. There were not


_____________________________________________________________________________


any species or habitats of significance (i.e. critical or natural) observed during field inspection that may be impacted. There are no recorded protected sites in the project area.

7.1.3. Impacts on Socio-economic Resources

334. Loss of Land: There is no loss of any agricultural or urban land through realignment of approach and exit roads to Bridge No 6 and also for Bridge No 5, as such there is no requirement of land. However, if only small parcels of land are required temporarily, such is the case for the construction yard, the impacts will be very minor.

335. The impacts of land acquisition can be mitigated as follows:

(i) No physical displacement of people, either on an individual household basis or through the acquisition of public properties such as schools, mosques or other community centers will occur.

(ii) Stockpiles and construction camps to be located on lower value land or public land.

336. Air Quality: There will be emissions from construction vehicles and equipment, although this will be temporary and is not expected to be a significant contributor to overall greenhouse gases.

337. Since the impact on air quality is likely to be minimal and associated with construction stage only and machinery will be maintained and serviced regularly to minimize emissions, the standards are not expected to be exceeded.

338. Dust: Dust from the movement of construction vehicles can cause a nuisance for neighboring property owners in regards to shops and residences. Dust is likely to already be a nuisance to road users in the vicinity of the proposed works as the roads are currently unsealed. The potential for additional dust generation during construction (from machinery movements and earthworks) can be mitigated by:

(i) Regular watering within each individual site formation area. (ii) The Contractor shall frequently clean and water the site to minimize fugitive dust emissions (iii) Watering of exposed surfaces shall be exercised as often as possible depending on the circumstance.

339. Water Quality: There is potential for an increased suspended sediment load in the watercourse during construction works that are within the bed of the creek or from runoff from surrounding earthworks. There is also the potential for oils and hydrocarbons from machinery to impact on water quality during construction.

340. It is noted that potential impacts on water quality are temporary and relate to the construction phase only. These impacts are expected to be no more significant than the periodic flood conditions, when the level of suspended sediment in rivers naturally increases.

341. Earthworks as part of the projects will have roughly equal cut to fill and so it is not expected that there will be excess materials or spoil to dispose of following construction works. Earthworks are also not significant and therefore it is not considered necessary to have a spoil management plan. Water quality impacts for proposed works can be mitigated as follows:

(i) Effective construction supervision to ensure the above measures are implemented (ii) Minimize any machinery movements within creek beds (iii) No machinery refueling to occur within 20 m of watercourses (iv) Install river bank protection measures (gabion baskets etc.) at bridge abutments (v) Locate stockpiles away from watercourses

342. Waste Storage and Disposal: During construction waste will be generated by construction workers (general waste and packaging), and through the replacement of existing structures which will require old structures to be demolished.

The remainder of the non-toxic material may be provided to the local community (if useful) or will be taken offsite and disposed of to an appropriate location (determined by Baljuvon local administration). The impacts of solid waste storage and disposal will be mitigated as follows:

(i) Prepare and implement a Waste Management Plan (WMP) as part of CEMP before construction to cover all aspects of waste storage disposal and accidental spills. The WMP is to be approved by the CSC (SMEC). Contractor to implement the WMP provisions.

(ii) All solid waste will be collected and removed from the work areas and disposed in local waste disposal sites as identified by the waste management plan.

343. Terrestrial ecology: Terrestrial ecology may be impacted during construction through noise, dust and vibration. Given the works will be temporary, there are not likely to be any endangered or rare species, and most species will be able to move away from the source of the disturbance, it is not considered that there will be significant adverse impacts on fauna.

344. However, to limit the impacts the following will be undertaken:

(i) As far as practicable, limit the use of machinery that causes vibrational impacts. (ii) Construction machinery will be maintained to a good standard and shall be equipped with muffler silencers.

345. Aquatic ecology: The reconstruction/rehabilitation of Bridges has the potential to impact on aquatic ecology through decreased water quality, disturbance to river/creek bed sediments and vibration from piling during construction period.

346. The rivers are seasonal, therefore no significant species are available in the vicinity of the proposed works. No native, endangered or rare or critical or natural habitats that may be impacted by the construction activity.

347. Water quality impacts and appropriate mitigation measures has been discussed under physical resources above. It is considered that with mitigation in the form of erosion and sediment runoff control, appropriate hazardous substances storage and disposal, and refueling of machinery at least 20m from watercourses, the water quality will not be significantly degraded and aquatic ecology impacts minor.

7.2.4. Assessment of Noise Impacts and Mitigations for Bridge No.5 and Bridge No. 6

352. Noise: The construction activities can lead to an increase in noise levels for users of the brТНРО anН roaН or nОarbв rОsТНОnМОs. TСО nОarОst МaПé anН rОstaurant to tСО ψrТНРО No 5 Тs 50m away and the distance of scattered houses from Bridge No 6 is 300m. It is considered that any noise generated at the site of the existing crossings will not impact on these receptors given their distance from the site.

353. Mitigation measures are as follows:

354. - The Construction Contractor, prior to the commencement of the construction activities, must develop and submit to Supervision Consultant a Topic Specific Environmental Management Plan – Noise Management Plan for the construction phase. The Plan must envisage all the existing technologies and best practice to avoid occurrence of noise and/or minimize the noise level

355. - Construction equipment and vehicles will be maintained to a good standard and shall be provided with muffler silencers.

356. - No construction works between the hours of 19:00 and 07:00 every day.

357. Basic noise level adjoining to the construction of the bridge 5 and 6 are within normal range. (photos 20 and 21), as the photos show, much more buildings are located nearby the bridge 5 compared to the bridge 6.

Figure 20: Baseline modelling results. Bridge No:5


_____________________________________________________________________________


Figure 21: Baseline modelling results. Bridge No:6 358. For the construction stage, noise level will exceed the norm for some buildings. Photos 22 and 23). As the photos show, in the event of the picture 6, noise will exceed the norm in case of few building only, whereas roughly twenty building located nearby the bridge 5 will be affected by noise.

Figure 22: Construction stage modelling results. Bridge No:5


_____________________________________________________________________________


Figure 23: Construction stage modelling results. Bridge No:6

359. Generally, noise of the construction for Bridge No.5 and Bridge No. 6 will be limited in active construction sites and can be short term. During the construction phase, the noise level increases and it will be higher than the admissible level at 445 buildings during the day. However, latest noise monitoring has indicated noise levels to be within the standards. Moreover, no construction works will be carried out during night. Furthermore, the impact of noise will be short-term and relevant mitigation measures will be developed within the scope of the project. In addition, noise monitoring will also be carried out during the construction of bridges to determine any exceedances in noise levels from the standards. Lastly, implementation of site specific noise management plan will also ensure any adversity of this impact is minimized.

360. As for the operation phase, noise level will significantly go down and will be less than basic as referred hereinabove. Since after the project implementation, the main course of the noise, floating coat will be superseded by the asphalt coating.

Table 44: Noise Generation Aspect, Construction and Operational Phases

Construction Phase Potential Impacts by Noise

Recommended Mitigation Measures and Monitoring Activities

During the construction phase, the noise level increases and it will be higher than the admissible level, however, the impact of noise will be short-term and relevant mitigation measures / plans will be developed within the scope of the project.

The Construction Contractor, prior to the commencement of the construction activities, must develop and submit to the Supervision Consultant a Topic Specific Environmental Management Plan – Noise Management Plan for the construction phase. The Plan must envisage all the existing technologies and best practice to avoid occurrence of noise and/or minimize the noise levels during this phase.


_____________________________________________________________________________


Communicate early on with the general public to reduce the number of noise complaints. Inform the public of any potential construction noise impacts and the measure that will be employed to reduce these impacts. Also, establish and publicize a responsive complaint mechanism for the duration of the construction; Use temporary sound barriers required for mitigation of noТsО ТmpaМts bв tСО МorrТНor’s ПТnaХ НОМТsТon НoМumОnt or environmental evaluation prior to transit line construction (where possible from a construction staging perspective). Minimize construction duration in residential areas, as much as possible. Minimize nighttime activities in residential areas, as much as possible. Re-route truck traffic away from residential streets, where possible. Combine noisy operations to occur in the same time period. Use well-maintained equipment equipped with modern mufflers. Noise blankets on equipment and/or quiet-use generators. NoТsО bХanФОts (aХso МaХХОН “aМoustТМ аraps”) arО rОmovabХО and reusable sound barriers made from compost materials like teflon impregnated cloth. The blankets are custom-fit to encapsulate the noisy equipment and block sounds at the source. These are commonly used on equipment such as fans and blowers, compressor housings, hydraulic pumps, etc. They are very effective because they block the source of the noise. Use alternative construction methods, such as sonic or vibratory pile driving in noise sensitive areas. Pile driving and other high-noise activities during daytime construction (generally 7am to 7pm), where possible. When construction time is restricted to certain daytime hours, the overall duration of project construction would likely increase.

Post-Construction and Operations Potential Impacts by Noise

Recommended Mitigation Measures and Monitoring Activities

In line with the modeling results, in the operation phase, the noise level will not exceed the admissible level at either of the buildings, either following the project implementation or in 2025 and 2033

During operation phase the will be no noise impact.

7.3 Operational Impact


361. Air Quality: Once constructed the Bridges, the projects will not significantly increase vehicle emissions that contribute to greenhouse gases. Although more vehicles may use the road if the crossings are improved as part of the project, the structures that are two lanes will reduce the existing stopping and starting associated for waiting for other vehicles to clear the crossing and so will reduce emissions.

362. Dust: On completion of the works, the new crossings will cause no on-going dust issues, and may reduce dust if the road approaches are sealed.

3. Environmental Management Monitoring Plan for Bridge no.5 and 6

3.1 Environmental Management Plan

382. During reconstruction / rehabilitation of the 2 Bridges, effective site management is required to ensure that MOT delivers on sustainable development and that works are conducted Тn a mannОr tСat saПОРuarНs Мountrв’s ОnvТronmОnt. ADψ’s SaПОРuarН rОquТrОmОnts Тs tСО development of an environmental management system and Environmental Management Plan to ensure all the recommendations of the formal impact assessment phase of the project move forward to the implementation phase. As such, Site-specific Environmental Management plan for these 2 bridges need to be prepared by the Contractor considering as a base of this UIEE-EMP. The EMP will be updated by the Contractor and submitted to PMCSC for review and PIU for approval prior to commencement of works. The plan shall be approved by the PIU. PIU will ensure that the Site-Specific Environmental Management Plans (SSEMP) and any Topic-SpОМТПТМ EεP’s are fit for purpose and accurately reflect the findings of the Impact Assessment process as set out in the current document. The Table 55 includes a general management for the 2 Bridges. εorОovОr, tСО EεP аСТМС аТХХ bО usОН as a basТs Пor tСО ωontraМtor’s EεP. A numbОr oП mТtТРatТon measures will be the responsibility of the Contractor who will be required to identify the best means for mitigating an impact as per the EMP, therefore the costs will be borne by the Contractor as part of the construction cost.

383. The environmental assessment (Updated IEE) of the construction and operation stages of the 2 Bridge Projects has determined that they will have relatively minor and site-specific impacts on the local environment. Environmental mitigation measures have been proposed to avoid or minimize environmental impacts to acceptable levels.

3.2 Environmental Monitoring Program

384. Environmental monitoring is a very important aspect during re-construction and operation stages of the project to safeguard the ecosystem. An environmental monitoring program for the construction and operation stages of the 2 Bridges will be undertaken to monitor environmental impacts of the Project, to determine conditions requiring remedial measures and to assess compliance with national and ADB environmental safeguard policies. In response to the environmental impact preliminarily identified during the study, an environmental monitoring plan has been developed and is presented in Table 56.

385. As indicated in Table 56 the contractor will be responsible in implementing the management and monitoring program and preparation of monthly progress reports regarding implementation. The Project Consultant will undertake the environmental monitoring program during the construction stage and will also monitor compliance of the contractor with the implementation of required mitigation measures and contract provisions pertaining to environmental aspects. During operation, the MOT staff will implement the monitoring plan.

386. The following measures will be taken by the Consultant and by PIURR to perform environmental compliance with the EMP and Monitoring Plan during Project implementation:

i TСО tОnНОr anН МontraМt НoМumОnts аТХХ МХОarХв sОt out tСО МontraМtor’s obХТРatТons to undertake environmental mitigation measures set out in the EMP. The recommended


_____________________________________________________________________


environmental mitigation costs are included as separate items in the Bills of Quantities. This will ensure that there is specific environmental mitigation Budget which will be implemented as required (Appendix-O, Tender Document).

ii During the procurement, contractors will be encouraged to include these costs in their rates and present the mitigation cost as a line item in the Bill of Quantities.

iii Contractor will recruit an environmental, health and safety manager, who will be rОsponsТbХО Пor ТmpХОmОntТnР tСО МontraМtors’ ОnvТronmОntaХ rОsponsibilities. The manager will also be responsible for health and safety aspects of workers at sites (Appendix-N, Workers Health and safety).

iv PMCSC will conduct environmental monitoring and assist PIURR in implementing EMP and supervision the implementation of mitigation measures by the Contractor.

2. Adequate set of environmental and related management plans will be developed and applied during the construction and operation stages of the Project. All these plans included into the EMP should be clearly bound into construction and supervision contracts

3. Comprehensive environmental quality monitoring standards will be applied and, including best international practices followed

2. Consultations with local community and local Government representatives

392. Consultations with Mayor of Timurmalik Regional Hukumat, head of Jamoats, community members have been conducted during feasibility studies of the proposed Kangurt-Baljuvon road for preparation of this IEE report. Discussions were held with the local people and Government representatives about potential impacts of the project and mitigation measures based on other ADB funded projects in the region. Mass consultations with the local people were held at Kangurt village and Baljuvon public conference ground on 01 November 2017 to let the local people know about the project activities to be carried out and their potential environmental impacts during construction. It was disseminated to them that project road development will be done within the right of way of the existing road. No cutting trees is generally expected. Only in some small sections trees can be replanted to other roadsides. Also, people may experience disturbances temporarily for movement during construction period.

393. The project will take all necessary measures to minimize the disturbances by adopting alternative access roads, keeping open the access to the houses and local roads, etc. Minutes of the meetings were signed by the local people. It was disseminated that EMP and monitoring program will be implemented during construction period to avoid/mitigate any potential impacts on air and water quality, disturbance of flora and fauna, improper waste disposal etc. It was also informed the people that they will have every right submit grievance/observation/opinion to the Grievance Redress Committee. A total of 37 people were present the Kangurt (see Photo 7) and 37 people at Baljuvon public conference hall. The consultation meetings were facilitated by Mr. Mirzoev Eraj, Deputy Executive Director of PIU, Coordinator of environmental and social safeguards in PIU. Among others, Ms. Ahmadbekova Guldavlat, Road Engineer, responsible for environmental issues in PIURR, PIU, Mr. Mahmadaliev Sherali, Social & resettlement Specialist, PIU, Abdurahmanov Saidkabir, Leading Specialist of PIU and Kh.

3. Grievance Mechanism

3.1 Grievance mechanism

394. Complaints and grievances received will be addressed through the following steps and actions:

Complaints will be lodged at the Jamoat level, where all the relevant representatives (land

and environmental specialists, Deputy jamoat chairperson, responsible for gender policy,

Jamoat Resource Center representatives), representatives of the affected households and MOT representative, will attempt to resolve the issue. A standard grievance registration form

was prepared and given for comments and perusal to Hukumats and Jamoats officials. Each

complaint will be registered, signed by the affected person and a representative of the

Grievance Redress Committee, and the receipt of the complaint given to the affected person. The period fixed for resolution of complaints is 14 calendar days the latest.

If the complaint is not addressed at Jamoat level, Affected Person will apply to the district

level LAR Committee/Working Group for solution. The LARC should invite MOT/PIU

representative once they have registered the complaint. Similar to Jamoat level, the complaint will be applied to the register and all the complaints from the Aps recorded. The

period for resolution of a complaint is 16 calendar days.

If no solution is reached within 16 days, the affected person can submit her/his case to the

appropriate court of law, with all costs paid for by the project.

3.2. Consultation and Information Disclosure of Bridge No. 5 and Bridge No. 6

397. The reconstruction of 2 RCC Bridge Projects were discussed at the meeting in Baljuvon District Office and questions were targeted at identifying any particular values and uses of the sites and to gain an understanding of the surrounding land uses and economic and social environment. It also allowed the project team to gain information on any particular issues or concerns for the environmental report to specifically address.

398. Public consultations were undertaken on 16 November 2018 Chaired by Ms Zoirzoda Marifat, Mayor of Baljuvon Town. Meetings on the Projects were held with men and women and a sample checklist about the Project was used. All persons consulted said they wanted the crossings to be upgraded and understood the need for reconstruction of Bridge No.5 and Bridge No. 6 to RCC type with 2 lanes.

399. Benefits of the project were seen to be:

(i) The reconstruction of the crossings would bring significant economic benefits as it would continue to allow large trucks carrying produce and tourism businesses to the area;

(i) AХХ sОasons’ aММОss аouХН СОХp ОvОrвonО Тn tСО arОa. εТМrobus anН otСОr transport services will comfortably use the bridges in flood conditions.

(ii) The new construction of the crossings would provide for efficient continuity of access from Kangurt to Intersection of Vose-Khovaling Road via Baljuvon. Further, enhance accessibility to markets, schools and residences.


_____________________________________________________________________________


400. There were no specific environmental concerns raised in regards to the Bridge reconstruction Projects. However, comments regarding the proposed reconstruction of Bridges included: (i) Higher level bridges in these 2 locations was the preference; and (ii) two lane crossings were preferred as a means to provide for vehicles as well as pedestrians and horses. No concerns were raised with impacts on fishing.

401. During project implementation, the contractor will provide a site office that people will be able to get more information about the works. The contractor is also required to communicate to the public, through public consultation and notice boards, the scope and schedule of construction as well as certain construction activities that may cause disruptions and access restrictions. Noticeboards and signs will provide information in English and Tajik languages (Detailed in Appendix-H, Public Consultation in November 2018).

IX. CONCLUSIONS

402. The Impact Assessment has been conducted in accordance with National legislative requirements and to the requirement of the Asian Development Bank in terms of the Environmental Safeguard requirements.

403. A wide range of potential effects were identified, with a focus on community and worker health and safety, followed by protection of water resources.

404. Based on the mitigation measures set out in the assessment process being fully implemented the project has two positive residual significant effects, these being reduced journey times, and improved access to facilities for local people and potential local employment during the construction phase.

405. Two adverse residual significant effects were identified, these both are at a Low Significance level and are risk of low level contamination of water courses from storm water run-off issues during operational phase if speed of vehicles is not effectively managed.

406. As the results of the baseline measurements and modeling demonstrate, the noise level, besides some exceptions, was within the norm near all buildings and premises found in the project zone. In line with the modeling results, for 53 of 755 buildings, the noise level exceeded the admissible level, during the day and/or at night.

407. During the construction phase, the noise level increases and it will be higher than the admissible level at 445 buildings during the day. . However, latest noise monitoring has indicated noise levels to be within the standards. Moreover, no construction works will be carried out during night time. Furthermore, the impact of noise will be short-term and relevant mitigation measures and plans will be developed within the scope of the project. In addition, noise monitoring will also be carried out during the construction of bridges to determine any exceedances in noise levels from the standards. Lastly, implementation of site-specific noise management plan will also ensure any adversity of this impact is minimized.

408. In line with the modeling results, in the operation phase, the noise level will not exceed the admissible level at any of the buildings, either following the project implementation or in 2025 and 2033.

409. The EMP, its mitigation and monitoring programs, contained herewith shall be included within the Bidding documents for project works for the new construction of RCC Bridge No 5 and Bridge No 6 of Baljuvon. The new design changes will not add any new activities, shifting of Bridge No 6 will bring positive impacts in terms of less adverse impacts on aquatic resources.

410. Based on the assessed design, the results of the Updated IEE indicate that the project has a limited risk of causing significant environmental impact and there are no substantive environmental reasons for the project not to proceed. As such, it is recommended that, the interventions should go ahead as soon as possible considering the environmental Acts and Rules of the Republic of Tajikistan, and ADB safeguard Policy Statement 2009.

Kangurt Baljuvon Khovaling road 1.1. Introduction

The hydrological studies were carried out for the reconstruction of Kangurt-Baljuvon-Khovaling road

and consisted in determining the maximum water discharge of all types of bridges and culverts.

Technical and financial viability of the bridge hinges upon proper estimation of the design flood and

requires extensive analysis of the available data and use of appropriate models/techniques as per

acceptable engineering practices. The design flood can be estimated with the help of either analyzing

historical data of instantaneous peak discharge where such data is available or by using long term

rainfall data by developing synthesized hydrograph through one of the unit hydrograph techniques.

The availability of discharge data and rainfall data is discussed in the following sections.

1.2. Location The road with the length of 42.5 km runs along the hilly terrain of the South Tajik lowlands at elevations of 800-1000 m above sea level along the right-bank of the Kyzylsu-southern River. Hydrologically, the investigated basin belongs to the Pyanj River basin. The location of the road is shown in Figure 1-1. 1.3. Watershed Characteristics

The investigated area is located in the northern part of the South Tajik lowlands. The terrain is hilly,

but at the same time sufficiently divided by numerous dry logs and streams. The territory is covered

with a thick layer of loam, the surface of which is well-seeded, poorly eroded, and overgrown with

dense grassy vegetation. There is agriculture land available in some part of the basin.

The area is slightly moistened by precipitation, with up to 90% of the precipitation occurring during

the winter-spring period, but the daily maximum precipitation is quite high.

The slopes of the basins are steep in the upper and middle parts, rocky and strongly dissected by

numerous short tributaries, denudation funnels and cuts. Sharp fluctuations in air temperatures cause

intensive destruction of rocks, which led to the covering of the basins with a cover of detrital material.

Slide-rocks often descend to river beds and their numerous permanent and temporary tributaries.

The lower parts of the slopes are designed and take the form of typical foothills with a smooth relief.

The hydrographic network in river basins is well developed and is represented by both perennial

streams and numerous dry channels of temporary tributaries.

The road with the length of 42.5 km crosses 6 permanent watercourses by 6 bridges. At the same

time, two bridges cross the same watercourse, and one watercourse crosses a culvert.

The catchment area of the crossed watercourses varies from 1159 km2 (bridge No. 5 across

Shurobdar River) to 24.1 km2 (Mulkol River, where the culvert is located).

The hydrographic characteristics of these watercourses are shown in Table 1.

1.1.1. Bridge No.1 on Toirsu River

River is originating at the crest part of the southeastern part of Vakhsh ridge slope, which is

one of the sections of the main watershed of Vakhsh and Pyanj rivers.

The road crosses the river in its upper course, below the mouth of its large-left-bank tributary

Obishirin (Chorshahabulak) and upper the right-bank of Shulyuktu.

The river flows in a typical gorge embedded between Vakhsh ridge and its spur. The bed of

the river is well developed, composed of boulder-pebble material. The slopes of the ridge

are steep, rocky and strongly dissected by numerous short tributaries, denudation funnels

and cuts. The basin of the river is covered with detrital material cover due to the intensive

destruction of rocks.

The existing bridge in Kangurt (Bridge 1) of 2x20m without bank protection was built in 1971.

Due to the intermediate stream flow support, which prevents the passage of the mudflow

mass, the stream breaks into 2 branches, pressing against the banks, despite the

straightness of the stream.

The banks under the influence of the water flow are subject to erosion and collapse. At right

bank, upstream of the bridge, local market and dwelling are present is more sloping bank

and flooded with high-water floods. Below the bridge is sloping left bank and is also subject

to periodic flooding.

SRTM 90m DEM has been utilized for determination of watershed characteristics. On the

basis of 90 m DEM, the elevation in the watershed varies from 969 m at bridge site to 1868

m. Mean elevation (AVEL) is 1421.38 m. The basin slope (BS) is 0.3273 m/m whereas max

stream slope (MSS) is 0.0462 m/m as shown in Figure 2

Figure 2: DEM for bridge No.1 on Toirsu River

1.1.2. Bridge No.2 on Obishirin River

Obishirin (Chorshahabulak) and Mulkol rivers flow between two major floodplains of Toirsu

and Talkhak in similar orographic conditions. The road crosses Obishirin River twice with a

difference of 1.5 km.

The valleys of rivers are V-shaped, the slopes are relatively steep, and their surface is

represented by a thick layer of sandy loamy deposits, covered with vegetation.

The river valleys are flat and are occupied by residential buildings and agricultural lands.

The riverbed is shallowly cut into the bottom of the valley, variable in width, meandering,

moving from one slope to the next. The shores are subject to destruction under the influence

of the water flow. The riverbeds are composed of boulder-pebble material, on expanded

areas forming ridge deposits.


_____________________________________________________________________________


The road crosses Obishirin River twice. Bridge No. 2 (downstream) according to the scheme

of 1x15 m, built in 1978, is located just behind the bend of the river. On the bend, in the

immediate vicinity of the bridge, a powerful island formed upstream, dividing the stream into

two channels. The main stream flows at the left bank, where the main destruction of the

coast occurred. In the middle of the spring water is flows at the right channel.

Downstream of the bridge, a single, relatively straight creek is flowing with a tendency to

push the stream to the right bank. Here on both sides is the village of the same name, whose

inhabitants planted the banks of the river with trees to prevent their buildings from flooding

by flood waters.

In recent years, the most powerful flooding took place in year 1991, when flood water poured

from the banks. The bed is also subject to erosion.

On the basis of 90 m DEM, the elevation in the watershed varies from 881 m at bridge site

to 1576 m. Mean elevation (AVEL) is 1251.86 m. The basin slope (BS) is 0.2348 m/m

whereas max stream slope (MSS) is 0.0415 m/m as shown in Figure 4.

The second bridge (No.3) is located upstream of Bridge No.2 at 0+600 RD of road. Elevation

in the watershed varies from 885 m at bridge site to 1576 m. Mean elevation (AVEL) is

1134.89 m. The basin slope (BS) is 0.2881 m/m whereas max stream slope (MSS) is 0.0294

m/m as shown in Figure 3.

1.1.3. Bridge No.3 on Obishirin River

The road cross Obishirin River by bridge No.3 just after passing Darak Town, and before

passing right bank of Obishirin River. The river along the road flows in a single channel of

variable width (8-20 m) with steep erosion banks.

The existing structure is built is single span of 1x15 m. Presently, there is no bank protection

along the bridge, despite the fact that there is prominent scour around its banks and are

eroded. Even foundations of bridge abutments are washed away and there is about a gap

of about 1 m is formed. Downstream of the bridge, the river turns almost at a right angle,

increases water level at bridge due to backwater affect.

On the basis of 90 m DEM, Elevation in the watershed of Mulkol River varies from 874 m at

the site of culvert to 1130 m. as shown in Figure 5.

1.1.4. Bridge No.4 on Talkhak River

Talkhak River originates in the southern spurs of the Vakhsh Range, in its central part. In

the upper and middle parts of the watershed area, there are significant numbers of

permanent streams that contribute runoff in the Talkhak River.

Bridge No. 4 is three span (3x15 m) is located on a rectilinear site and crosses the river

before entering Baljuvon. The riverbed is flat with low, sometimes steep banks. Presently,

there is no bank protection along the bridge, despite the fact that there is prominent scour

around its banks and are eroded.

The river has substantial load of sediment with flow, due to which sediments has

accumulated in the center of the bridge and flow mainly passes at the left and right side of

abutments.

1.1.5 Bridge No.5 on Shurobdara River

Shurobdara River is one the main creek of the Talkhak River that originates from Archatuk

Pass. The river flows in the direction of south west. In the upper reaches the river flows in

a narrow, poorly developed valley. The riverbed and floodplain of the river are deeply

embedded in the bottom of the valley and the canal often branches into sleeves.

The road crosses the river above the inflow of a large left-bank tributary - Obimazor River

and the right bank - Talkhak River. The main water content of the river is created by

numerous tributaries of the mountain part of the basin, feeding on abundant spring waters.

Bridge No. 5 with a total length of 191m (9 spans) crosses the river on a wide floodplain.

Due to the large wandering waterway, the main stream is currently concentrated near the

right bank, adversely affecting it during flood season. In the end right-bank span is laid

artificial channel for the diversion of water for irrigation of land.



whereas max stream slope (MSS) is 0.0222 m/m. The watershed map is shown in Figure

7.


_____________________________________________________________________________


Figure 7: DEM for bridge No.5 on Shurobdara River

1.1.6 Bridge No.6 on Obimazor River

After passing the bridge on Shurobdara River the road descends into the floodplain of

Obimazor River and passes along right bank. The road crosses Obimazor River at KM

23+000

Total length of the bridge is 134 meter with a significant skew on the part of the stream

wandering up to 300 m wide. The bridge on the right bank blocked the main flow direction

of the long dam, which is constantly destroyed during the floods. Due to the tendency of the

aspiration of the stream to the right bank, the left-bank spans during floods basically are out

of operation. To protect against erosion located above the bridge of the dam in the right-

bank span, a self-made dam was built, but it only reduced water-carrying capacity of the

bridge. Despite the considerable length, the bridge is not able to pass flood water, as can

be seen from the characteristic traces on the bridge (even the perimeter fences on the upper

side of the bridge is damaged). This is due to the fact that in the left-bank of the bridge

deposited sediments preventing the passage of the flow.



whereas max stream slope (MSS) is 0.0245 m/m. The watershed map is shown in Figure

8.

1.2. Hydrological Regime of the rivers

The main factor determining the water regime of rivers is the nature of the feed, which is

determined by the magnitude and seasonal distribution of precipitation, air temperature and

other climatic factors.

The rivers in the basin can be categorized as rainfall-snow rivers as per standard

classification. The runoff is generated from rainfall as well as melting of snow. Studies of

these rivers document diurnal cycle. First peak is observed from end of January to the

middle of March. Due to the relatively low altitude of the catchment area, the duration of

high water on such rivers is not long - 110-160 days. The largest annual runoffs are mainly

in April-May (less often in March, June). Mostly these peak floods are originated from rainfall

are very frequent. The duration of these floods is short-term but produces lot of havoc with

flood and destructive mudflow. The power of the mud flows, not only, depends on the

amount and intensity of the precipitation, as well as on the presence in the basin of a readily

mobile and easily washable loamy material involved in the flow.

The hydrograph of peak floods includes contribution with rainfall along with base flow of the

river. The rivers normally has low flood from June and continues until next season. Runoffs

during this period are not subject to significant fluctuations and are favorable for

construction.


_____________________________________________________________________________


Ice formations in the form of coasts are observed almost every year, from December to

February, their duration ranges from 0-40 days. On periodically operating logs and cuts, the

flow period is limited by the period of snowmelt and rainfall.

1.3. Data availability and collection

There are sufficient number of flow gauges maintaining long time flow data measurement.

The maximum daily instantaneous flow of more than 35 years is recorded as shown in Table

2.

During the period of 1980 to 88, flow gauging station at Khonako on River Obimazor River

(lower reach) had been operated. Although, observations were carried out only for the river

level. The gauge was closed because of constantly occurring channel deformations, as a

result of which the levels are not comparable.

A flow gauge is available at Yakhsu River near Karboztonak. The data of this gauge is

transformed to Obimazor River as both basin have similar topographical and climatic

conditions and the difference in the catchment areas is less than 10 times.

Hydrological gauge on Kyzylsu River at Babakhanshaid estimates the runoff from the

mountainous catchment area, so its observations can be used in calculations of the

maximum runoff in section line of Bridge No. 5 across Shurobdara River.

Hydrological gauge on Toirsu River near Shahbur is located in the middle part of the

catchment area. From the bridge section to the hydrological gauge, the river does not take

significant tributaries and in this area there is a partial loss of flow, so its observations cannot

be used in calculating the maximum runoff in the bridge section line.

1.4. Determination of the maximum runoff

Various methods have been adopted for the estimation of maximum runoff. The runoff for

bridge No. 1 to bridge No. 4 is estimated using rainfall runoff modeling. An empirical method

(standard practice in Tajikistan) used for the runoff estimation. One day annual maximum

rainfall in this region is observed is 83 mm and is used for runoff estimation. The calculation


_____________________________________________________________________________


for these four bridges is shown in Appendix 1 to 3. The estimated design flood for 50 years

and 33 years is shown in Table 3.

For Bridge No. 5 across Shurobdara River, design flood was estimated on the basis of long-

term observations at Kyzylsu River gauge at Babakhanshshaid , located 11 km below the

bridge section line.

Kyzylsu River that lies in the same mountainous region, analytical distribution method is

used for the estimation of flood for 20 and 50 year return period and shown below

50 вear return perioН flooН (2% ВПΨ - 850 m3/s;

20 year return perioН flooН (5% ВПΨ – 710 m3/s

The recommended formula for carrying the maximum water discharge of rainfall flood from

the gauge to the bridge section line is:

Q = Q / (F :F/)n

The value of n for Kyzylsu River is calculated from formula: Q = FnB1/3I1/4

Where;

F-catchment area, km2

B- width of the river, km

I- river slope, /

With the initial data: F=1790 km2; =Қ7λ0μ87=қ0,6 Фm; I=23 /

n 2%=0,66; n 5%=0,64


_____________________________________________________________________________


Proceeding from the obtained values, the calculated maximum water discharge in

Shurobdara River in the section line of the bridge:

Q2% = 850 (Ққ00 μ Қ7λ0)0,66 = 652 m3/s; Q5% = 7Қ0 (Ққ00 μ Қ7λ0)0,64 = 550 m3/s

For Obimazor River design discharges are calculated by several methods. That includes;

Analogy method

Data of Yahsu River at Karboztonak has been used for analog method:

қ0 вОar rОturn pОrТoН ПХooН ( 5% ) – 1250 m3/s

33 вОar rОturn pОrТoН ПХooН (3% ) - 1500 m3/s;

50 вОar rОturn pОrТoН ПХooН (қ% ) - 1750 m3/s;

The basic formula for determining discharges by analog method is as follow:

Q = Q (FnB1/3I1/4Ψ μ (F nB 1/3I 1/4)

The index of the degree of reduction in the vigor of the flood of Yakhsu River is calculated

similar to the previous calculation.

As F=1440 km2; =Қ440μλ0=Қ6 Фm; I=28 /

n 2%=0,79; n 3%=0,76; n 5%=0,74

Q2% = 1750 0,қ850,79 0,677 = 440 m3/s

Q3% = Қ500 0,қ850,76 0,677 = 3λҚ m3/s

Q5% = Ққ50 0,қ850,74 0,677 = 334 m3/s

The comparison of the modules for the maximum discharge of Obimazor and Yakhsu rivers

showed a lower value in Obimazor, which indicates a lowering of the received discharge,

since for undistorted mode the flow modules increase with decreasing area.

For the rivers of the Amu Darya basin, based on the results of field observations, a

methodology has been developed for determining the maximum floods of rivers that have

not been studied, taking into account the demarcation of the area, depending on the type of

dependence of the discharge characteristics of the water beyond the height of the basin

and, as a consequence, the prevailing feeding factors of the river.

The average long-term value of the maximum modulus of runoff is determined by the

formula:

average.max. = [0.325 haverage.μ (1.λ3Δ + 0.04 √ h .Ψ] + А μ F0.55 l/s s1 km2

haverage – layer of runoff in high water, mm. It is determined by the dependence on the

average height of the catchment area;

where;


_____________________________________________________________________________


Δ – root-mean-square deviation of heights, km;

μ F0.55 – average long-term value of rain surcharge;

– parameter that takes into account the features of the structure of river basins;

F – catchment area, km2.

The coefficient of variation of the maximum annual water discharge is recommended by the

formula:

Q2%=ққ8 қ,қ4=5ҚҚ m3/ Q3%=ққ8 қ,Қ4=488 m3/s Q5%=ққ8 Қ.λқ=438 m3/s

The above results are taken as calculated for the bridge across Obimazor River.

1.5. Estimation of mudflow

Mudflow activity is widespread in the study area. The accumulation of loamy material moves

with water pressure greatly increases the flow of water passing in the streams.

The maximum discharges of mudflows of rain origin are calculated by the formula:

Qc= QВ Qmm3/s

Q – discharge of liquid runoff, m3/s

ΨQ– coefficient of solid flow

The calculation of the discharge rate of liquid runoff (the maximum rainwater discharge) is

based on the maximum flow intensity formula applicable for mountain areas:

Q % = q1%φ 1% А m3/s

1.6. Hydraulics Analysis

The design of a new bridge or rehabilitation of an existing bridge across river requires

hydraulic analysis to determine the flow parameters and behavior to the bridge axis and

along a reach upstream and downstream of the bridge where flow parameters are expected

to be influenced by the bridge. The hydraulic analysis and design involves following steps:

Computation of water surface profile along the reach for design flood to establish

the flood conditions with and without the bridge

Determination of highest flood level (HFL) and flow velocities along the reach and

at the bridge axis

Computation of scour depth at the bridge axis and along the proposed training

works

Layout and design of river training works to smoothly guide the flow into the bridge

site.

Design of protection works for bridge abutments, piers and guide banks

1.6.1. Hydraulic Analysis for the bridge at Obimazor River


_____________________________________________________________________________


This bridge is the most problematic. First of all, when the bridge was located, it was

necessary to take into account the aspiration of the water flow to the right bank, and not to

cover the main direction with dams to take the main load from the water flow, the pale of

the supports created an obstacle for the passage of solid material.

A new bridge is needed here, and first of all, with a change in its location to avoid oblique

intersection. In order to avoid costly regulatory dams, which are constantly destroyed, it is

desirable to cover the entire zone of river wandering belt with spans of at least 30m.

Unfortunately, the bridge is subject to reconstruction. In this case, in addition to

strengthening the flow control abutments, it is desirable on the right bank, where the stream

tends to the right bank, to construct a spur to redirect the main channel. In this case, the

length of the spur, the angle of its inclination should be such that the flow is directed to the

center, and not to the opposite bank, where a situation similar to the current one can be

created.

1.6.2 Waterway and velocity

On wandering rivers with a considerable width of the river spill, a channel of steady width is

formed, where the main part of the water flow is concentrated. At the same time, due to the

attraction of a considerable amount of solid riverbed material by the flow, the main riverbed

can be formed both on one shore, and at the center or at the opposite bank.

The width of a stable watercourse is determined by the formula:

В . = А (Q0,5 . :i0,2)

With a channel-ПormТnР ПХoа ratО oП 5% , ОquaХ to 438 m3/s, the longitudinal slope of the

river is 0.013 and A = 1.0 (for a foothill area with eroded banks):

В . = 1,0 (4380,5. : 0,0130,2) = 50 m

This value is confirmed by the materials of the field survey.

It is considered that on the width of the stable channel may be concentrated from 80 to

100% of the calculated flow. Taking into account the existing situation on the bridge section,

with further hydraulic calculations, 100% of the design discharge rate is calculated on the

width of the stable channel.

Under such conditions, the depth of the stream under the bridge will be 2.53 m at a flow

vОХoМТtв oП 4.04 m/s, anН қ% (50 вОar rОturn pОrТoН ) аТХХ СavО a marФ oП λ46.70.

To confirm the obtained values, is prepared calculation of the possible backwater during

proportional spreading of the flow along the whole width of the bridge hole and its

concentration on the width of the stable riverbed.

Taking into account the oblique intersection, the waterway of the bridge is 103m, while the

entire waterway is operating, the depth of the stream will be 1.64 m at a flow velocity of 3.02

Since the erosion that occurs during runoff reduces the amount of backwater, the calculation

takes into account the deepening of the channel during the passage of the flood. When

calculating by recommendation, 50% of the erosion is taken into account.

Deep erosion during the passage of the peak of flooding stops when the flow rates and

dynamic equilibrium are equal. On this condition, a formula is derived for calculating the

depth of self-erosion during the passage of the flood. The movement of sediments in the

APPENDIX- C: AQUATIC BIOLOGY REPORT

Report of the Scientific Research Study of the Current State of the

Hydrophauna of the Surkhob River Tributaries of the Pyanj River Basin within the

projected Kangurt-Baldjuvan-Khovaling Road.

The Surkhob River originates near the village of Baljuvon after the confluence of tributaries

of the Talhak River, Obimazor, Mukal, Shurabdarya. The most abundant among these

tributaries is the Obimazor and Shurabdarya rivers.

In the lower reaches of the Surkhob River basin there are 9 species of fish, three of them:

ordinary marinka, Samarkand temple, Turkestan barbel have commercial value, and in the

upstream tributaries there are 5 species 2 of which the ordinary marinka, Samarkand

temple, are commercial and the three remaining species belong to the fishing non-target

species are Turkestan catfish, combs and Tibetan char. It should be noted that the

Turkestan sommer is an endemic species of mountain rivers in Tajikistan and Central Asia.

Common marinka, Snowtrout -Shizotorax intermedius McCleland is an aboriginal species

of the local ichthyofauna of the mountain and sub-mountain rivers of Tajikistan. In the

Surkhob River basin, it is mainly found above the Temurmalik village of the Temurmalik

district and in all the tributaries of the upper reaches of the Surkhob River. Spawning of an

ordinary marinka takes place in March-April after the release of 2-3 months, the larvae keep

instead of spawning and then slide down the rivers and spread throughout the basin and

places with good feeding conditions. The rate of growth of ordinary marinka in the

Shurabdarya, Obimazor, Mulkal and other tributaries is low. We caught specimens of

ordinary marinka have a length of 16.1 to 23.4 cm on average 20.0 cm. The weight of the

caught fish marinoks ranged from 35 to 200 grams on average 120

Photo 1: Common marinka

The basis of the food of ordinary marinka in the upper tributaries of the Surkhob river is

fouling, detritus from insects, caddis flies, footworms and insects falling into the water.

The gas regime in the tributaries of rivers is favorable for the survival and survival of aquatic

organisms and fish. According to data (Ahrorova, 1999), the amount of dissolved oxygen in

water varies from 6.10 mg / L in September to 10.7 mg / L in June. 12 species of benthic

animals were recorded in the Surkhob River; Shurobdara-5, in the river Obimazor-8. in

Shurabdarya there are 6 species. The highest water vegetation is almost absent with the

exception of some bays and caves where in places grows reed and sedge. Vegetative and

animal components in the tributaries of the Surkhob River are very poor in view of the stony-

pebble bottom of rivers and high turbidity of the water.

Samarkand khramulya - Varicorhinus capoeta heratensis natio (Stein). This species occurs

in all tributaries of the upper reaches of the Surkhob River in the river. Khovaling, Tira,

Shurabdarya, Obimazor, Talkhak and down to the confluence of the Pyanj River. Spawning

of Samarkand temple in these rivers takes place in May-June. Unlike the marinka, the larvae

of the temples in the warm-water rivers spend the winter and in the next year in the stage

of the year-old they roll down. The length of the Samarkand samuruli caught by us in the

tributaries of the Surkhob River has a length of 16.5 to 22.2 cm on average 19.5 cm, with

an average weight of 30 to 115 g. 50 g. Silt, detritus and sediment are used for food.

Photo 2: Samarkand khramulya

Turkestan catfish - Glypthosternum reticulatum Mc Cleland. Low-value commercial fish. It

occurs in the Surkhob River basin in its tributaries Khovaling and Tira. It leads a bottom way

of life. The size of the Turkestan catfish in the tributaries of the river ranges from 8.0 to 8.0

cm on average 13.0 cm with a weight of 25 to 110 g., using the organisms of bottom

sediments. In the tributary of Shurabdarya it is very rare.


_____________________________________________________________________________


Photo 3. Turkestan catfish

Weed-laying fish in the tributaries of the Shurabdarya are represented by the following

species: the scalloped char, the Tibetan char, which is a representative of the local

ichthyofauna.

Eastern crested loach, Loach - Nemachilus malaptherurus longicauda Kessler / Cretaceous

char around the Surkhob River Basin is found in the tributaries of the River Thira and

Obimazor. For feeding and searching for food, it enters the Surkhob River and descends on

it to the village. Temurmalik below this zone the crested loach was not found by us. The

length of the crested loach varies from 7.0 to 17.5 cm and weighs from 9.2 to 32 g., the

spawning of the crested loach takes place in May-June.

Photo 4. Eastern crested loach

Tibetan stone loach - Nemachilus stoliczkai Steindachner. As well as the combed loach

occurs in the tributaries of Obimazor, Tira, Hovaling. The length of the body of the Tibetan

char is between 8 and 14 cm, with a weight of 10 to 25 g. spawns at the end of May to mid-

June. Food Tibetan char in the tributaries of the rivers are water and air insects, mostly

footworms, vesnyanki, larvae of dragonflies and other organisms.


_____________________________________________________________________________


Photo 5. Tibetan stone loach

In conclusion, it should be noted that the ichthyofauna of the tributaries of the upper reaches

of the Surkhob River as well as Shurobdara, Obimazor as other mountain rivers in Tajikistan

is not very rich in species. In the plains there are from 5 to 9 species in the upper sections

of 3-4 species of fish. Species composition and fodder base of fish in these tributaries in the

spring period suffer greatly from mudflows.

The construction of the highway Kangurt-Baljuvon-Khovaling in the area of tributaries of

Shurabdarya in no way affects the composition and abundance of the aquatic biology of the

named tributaries.

APPENDIX- I: NOISE SURVEY AND MODELING 1. EXECUTIVE SUMMARY

1. The project entails complete rehabilitation of the existing road bed and wearing courses. The rehabilitation will not entail widening of the road, except in some minor locations where road curvature is being eased by minor realignment. The project remains within the existing length of 43 km Right of Way (RoW) and no new land take is required, even for the reconstruction of the Bridge No. 5 and Bridge No. 6.

2. The project proposal includes the rehabilitation of four bridges and 27 culverts which cross water courses, the remaining 2 metal Bridges (Bridge No. 5 and Bridge No. 6) will be reconstructed in to RCC type. A new raised embanked road bed of 1.6 km (approach to Bridge No.6) will be developed within the flood plain to the east of Baljuvon where the old road has been completely lost to water erosion. Scour protection within the flood plain and at bridge abutments will be developed. The project has developed a comprehensive hydrological study to aid design of these structures and ensure the project does not cause upstream flooding by blocking the water courses during river spate conditions.

3. The project is for rehabilitation of a two-lane rural road which runs from the town of Kangurt in a mainly eastwards direction, passing through Buljuvon, to the junction with the recently upgraded Kovaling Road at km 23 (Vose-Khovaling Road). The existing, and the new road, consists of two lanes only and is a Category IV road in accordance with Tajikistan Standards for Highways.

4. The project zone crosses 6 settlements of different sizes: (i) Kangurt; (ii) Mlukon; (iii) Khanabad; (iv) Khirob; (v) Baljuvon; and (vi) Shagmon. The buildings and premises in the above-listed cities and settlements are located both, adjacent to the project zone and quite far from it. The buildings adjacent to the project road are the ones housing both, small and medium businesses as well as residential houses.

5. 24-hour-long continuous baseline noise level measurements were accomplished at two points adjacent to the buildings and premises, and at the third point additional a 7-hour-long continuous baseline noise level measurement was accomplished within the building (during the day).

6. The data were taken in every two seconds. Total 43000-44000 data were obtained from every point (during 24 hours). As the basic measurements demonstrated, the noise level adjacent to the project zone both, during the day and at night except for a few exceptions (7%) is within the admissible norms.

7. It should be noted that the baseline noise level measured at the first point was 2-3 Db higher that the baseline noise level measured at the second point. The reason for this was the rain falling continuously at the stage of doing measurements at the first point.

8. The project zone belongs to mountain areas. There are small villages in the project zone and in the adjacent areas. There are 6 settled areas located adjacent to the project zone. The project main crosses all of them.

9. In order to establish the existing and expected noise levels, noise modeling was undertaken at four stages: (i) noise level modeling for the existing situation, (ii) noise level modeling for the construction stage, (iii) noise level modeling at the operation stage by 2019, and (iv) noise level modeling at the operation stage by 2025 and 2033.


_____________________________________________________________________________


10. Modeling was done by using computer software CadnaA.CadnaA (Computer Aided Noise Abatement) is the leading software for calculation, presentation, assessment and prediction of environmental noise. Whether your objective is to study the noise emission of an industrial plant, of a mart including a parking lot, of a new road or railway scheme or even of entire towns and urbanized areas: CadnaA is designed to handle all these tasks.

11. For the modeling of the existing noise level the following data were used: (i) the results of the 24-hr measurements of the existing noise levels at 2 points in the project zone; (ii) the data of the existing traffic analysis; (iii) strength and direction of the wind; (iv) maximum allowed traffic speed (speed limit), and (v) the type and quality of road pavement.

12. As the results of the baseline measurements and modeling demonstrate, the noise level, besides some exceptions, was within the norm near all buildings and premises found in the project zone. In line with the modeling results, for 53 of 755 buildings (7 %), the noise level exceeded the admissible level, during the day and/or at night.

13. During the construction phase, the noise level increases and it will be higher than the admissible level at 445 (58.9%) buildings during the day. At night, no construction works will be carried out. However, the impact of noise will be short-term and relevant mitigation measures will be developed within the scope of the project.

14. In line with the modeling results, in the operation phase, the noise level will not exceed the admissible level at either of the buildings, either following the project implementation or in 2025 and 2033.

Recommendations

15. The following major recommendations were developed in the noise management process:

The Construction Contractor, prior to the commencement of the construction activities,

must develop and submit the Supervision Consultant a Topic Specific Environmental

Management Plan – Noise Management Plan for the construction phase. The Plan

must envisage all the existing technologies and best practice to avoid occurrence of

noise and/or minimize the noise level;

At the modeling stage, the maximum admissible speed is taken in line with the

requirements of the effective legislation of Tajikistan, under which maximum

admissible speed is 60 km/hr for small settled areas and is 40 km/hr for large

settlements. Consequently, speed limit signs are necessary to provide along the

project road;

At the modeling stage, the value of increase of the present vehicle flow is taken annual

3% proposed by the consulting company. If, as a result of the project implementation,

an increase in the vehicle flow exceeds the forecasted value, additional studies will be

necessary.

2. FUTURE TRAFFIC FLOWS

16. Traffic counts for the existing road have been conducted on two occasions. The first was

in June 2017 and the second in October 2017. The results of the two sets of counts show some high percentage variations. The June 2017 counts did not cover a full 24-hour period and were conducted when an alternative route, the Vos – Khovaling road was still under rehabilitation so there may have been some diverted traffic using the Kangurt to Khovaling Road.

17. On this basis the October 2017 counts are summarized and presented below. Counts were conducted at three locations:

Kangurt (start of project);

Baljuvon (middle of project); and

Intersection of road with Vose – Khovaling Road (end of project).

18. Six-hour counts were conducted at each location over four days and for a different six-hour period each day as shown in Table 3.

Table 3: October 2017 Traffic Count Dates

Count No Date Time

1 12/10/18 06:00 to 12:00

3 14/10/18 18:00 to 00:00

4 15/10/18 00:00 to 06:00

19. The results of these counts are presented in Table 4. In the table provides a breakdown

of the main motorized vehicles using the road. It can be seen that heavy vehicles are relatively low in number, making up some 6 % of total movements on the route.

20. There is a gradual decline in road use from west to east, indicating that traffic is mainly

local and entering the road at Kangurt and stopping at villages along the route.

21. The counts also showed a strong tendency for the traffic to be diurnal with the maximum number of vehicle movements at any of the count points for the midnight to 06:00 hrs period being 70 vehicle movements. This represents approximately 10 vehicles movements per hour on average.

22. Predicted increases in traffic movements are 3% per year. The rehabilitation will make the route more accessible to local people and some minor increases in local traffic movements are to be expected. However, there are other key routes available for long distance travel, including from Khovaling to Dangara and then to the capital city, Dushanbe on a newly rehabilitated road. The 3% increase in movements is based on World Bank predictions of a 3% growth in GDP which they state will result in a concomitant 3% increase in traffic flows on the national highway system.

23. Using a compounded 3% growth and a 15-year project life, then traffic movements will increase by some 60% by 2034, giving rise to predicted movements in the range of 780 -800 per day.

3. EXISTING SITUATION

24. The project is located in a rural setting with a predominant land use for agriculture, either as managed grasslands for grazing of animals (sheep and cattle), orchards with fruit and nut trees and arable land. In the higher areas of land, the pasture has an upper storey consisting of wild fruit and nut trees.

25. The route alignment is within low mountains and valleys which are intersected by often water courses which are often highly braided in nature and in some instances located within very wide flood plains. Photo 1 provides examples of these river features.

26. Areas of urbanization along the route are few and generally small in nature. Areas of habitation are shown in Figure 2. Many of the villages and clusters of houses are set back from the existing road. Notable areas of habitation include Kangurt, Baljuvon, Sarimazor and Shagmon.

Figure 1: Areas of urbanization along the route alignment

3.1 Land Use along Route Alignment

27. A general description of the route follows, distances are approximate and based on chainage for the project starting at 0.0 km at Kangurt.

28. Km 0 to 1.6 km – The road commences at an approximate elevation of 870 m above sea level (asl) and passes to the edge of the village of Kangurt. Within this first 1.6 km the road crosses three bridges as shown in Figure 1.


_____________________________________________________________________________


29. Km 1.6 to Km 11.6 – On leaving Kangurt the route alignment rises steadily to reach an approximate elevation of 1210 m asl at 11.6 km. The route runs through agricultural land which is arable in nature, supporting crops such as cereals and oil seed rape. In some locations the original road construction has cut through low hills and exposed soil walls which have not vegetated over the intervening period. This section has limited tree cover, being restricted to small trees within the route alignment right of way.

30. Km 11.6 to Km 15.5 – at approximately the route alignment passes through an area of open pasture with scattered tree cover (wild fruit and nut trees) before descending to the village of Khanabad. Alongside the route are a small number of properties with the main part of the village lying to the south of the road alignment at a distance of about 100 m and screened by woodland. This area lies below the elevation of the road. The houses nearest to the route sit above the road elevation.

31. Km 15.5 to Km 20 – The route continues to descend before reach a low point of 870 m at approximately 16.4 m. From this point through to KM 20 the adjacent land use is again dominated by arable crop production. There are a limited number of residential properties along this section.

32. Km 20 to Km 21 – at this section the route passes through an area of orchard with cherry, apple and nut trees present.

33. Km 21 to Km 23 – this section of the alignment takes the road through the small town of Baljuvon, crossing bridge no 4 before reaching the edge of a major flood plain at Km 23.

34. Km 23 to Km 25 – at this section the route crosses a river which is flowing from north to south, at Bridge No 5, before running along the edge of a river flowing from the east to create a confluence. This section of the route is badly eroded, and no real trace of the original road is visible, the route running within the dry river bed section. The route crosses this east west water course at Bridge 6 before starting to ascend.

35. Km 25 to Km 35 – The route ascends from the flood plain, passing through a mosaic of land use, with areas of arable production interspersed with grassland with wild fruit and nut trees.

36. Km 35 to Km 38 – The route continues to rise with a notable increase in tree cover within this section. These are predominantly wild fruit and nut trees.

37. Km 38 – Km 43 – The road rises to the small village of Shagmon, which mainly consists of small agricultural units surrounded by open land and orchards, mainly to the south of the road alignment. The final section of the route passes through arable land before joining with the existing Khovaling road.

38. The Project corridor and its surroundings exhibit soil profiles characterized by typically loess, loamy sands and loamy soils, occasionally bench gravel upper Quaternary age, classically formed through deposition of light and typical grey earth, brown carbonate soils. Limitation - erosion, low content of organic in soils and drought in summer period. Soils in other areas are formed through wind deposition over arid or semi-arid areas. The humus layer of the loess and loamy sands is fairly fertile, and agriculture as noted by the extensive cultivation of the Obi Mazor, Surkhob, Vakhs and Yakhsu rivers floodplain. For these soils to be included into agricultural use they require irrigation and the use of mineral fertilizers.

3.2 Main Receptors

39. The main receptors, the noise will have an impact during the project implementation and operation phases are settled areas and existing fauna. The largest portion of the project road will run through the existing alignment, where, despite the fact that there is a local ground road, the traffic almost takes place.

40. There are both, residential houses and buildings housing small and medium businesses found adjacent to the project zone. These are mostly small trade objects, hotels, car service centers, fueling stations, etc. (Figures 2 and 3)

Figures 2 and 3: Small and medium commercial objects

41. As already mentioned, there are also residential houses adjacent to the design highway, with most of them being one- or two-storey buildings. Following the local traditions, the private land plots have the fences made of concrete or similar materials thus playing the role of noise attenuators (Figure 4-7).

Figures 4 and 5: Residential buildings and premises adjacent to the project zone


_____________________________________________________________________________


Figures 6 and 7: Residential buildings and premises adjacent to the project zone

42. The fact of the residential houses fenced with 2-2,5-meter-high concrete fence was not considered during modeling. However, it should be noted that the given fact will reduce the values of the existing and expected noise impacts.

Industries

43. Along the Project ROW, no industrial operations were noticed. There are no significant factories or light industrial activities in the area.

Agriculture

44. Irrigated land in Khatlon region amount to 338 thousand hectares, which equals 45% of the irrigated land in Tajikistan, rain-fed land 2.12 million hectares, gardens 22.5 thousand hectares, of vineyards 8.2 thousand ha. Meadows 1.2 million. m., living 16.8 thousand ha., backyard 86 thousand ha., and 400 hectares of saplings. Khatlon region is famous for its high quality cotton, early watermelons, melons, onions, a cement plant, the Nurek, Chemistry Works, the Yavan and Sarband, Vakhsh River, seating Chiluchorchashma, Mountain Childuhtaron, Nurek hydroelectric power station, the historic sites as the Castle “HuХbuФ” Тn VosО НТstrТМt anН МОmОtОrв HaгratТ AmТrУon.

4. RESULTS OF THE BASELINE NOISE MEASUREMENTS

45. Through April16-20, 2019, the specialists measured the baseline noise level in 2 points of

the project zone. The noise was measured continuously, for 24 hours and the data were

taken in every second. Total 43000-44000 data were obtained from every point. Noise

level measurements were done in village Kangu t and Baljuvon. Additional 7-hour noise

measurements were done on the territory of the office village Baljuvon. The measurement

was done on April 17.

46. SampХТnР аas НonО аТtС AmОrТМan noТsО mОtОr „REED 8080“.The noise meter was

calibrated by the Georgian National Agency for Standards and Metrology on April 23,

2018. Calibration Certificate: GE/MI 07-00474-18 (see Annex 3).

47. In the area, which immediately adjoins the residential houses and buildings of public

establishments, a noise measuring device was installed at least 2 m from the structures of

the buildings and at 1,5-2,0 m high from the ground level (See Figures 8 and 9).

Figure 10 and 11: Measurement point 2 – Village Kangurt 38.14.23.46 N; 69.31.34.56 E

48. During the measurements, the microphone was directed towards the main source of noise and was distanced from the entity making the measurements by at least 0,5 m. If it was impossible to identify the main source of noise in the area, the direction of the microphone was vertical and upwards.

49. The measurement points are shown in Figures 10 and 11. As for the 7-hour-long measurements in the building, they were done in the building adjacent the first point.

50. Tables 7 and 8 shows the averaged index of the data taken at 2 points of the project zone in a 24-hour continuous mode in every 1 hour. Table 9 shows the results of 7-hour-long measurements in the building.

5. MODELING THE EXISTING SITUATION

5.1 Introduction

51. As already mentioned, the project zone belongs to mountain areas. There are small villages in the project zone and in the adjacent areas. There are 6 settled areas adjacent to the project zone. Of the six areas, the road will cross only three, while at present, other 3 villages are distanced from the design highway by various distances.

5.2 Methods of 3D noise modeling

52. CadnaA (Computer Aided Noise Abatement) is the leading software for calculation,

presentation, assessment and prediction of environmental noise. Whether your objective

is to study the noise emission of an industrial plant, of a mart including a parking lot, of a

new road or railway scheme or even of entire towns and urbanized areas: CadnaA is

designed to handle all these tasks.

53. With more than 30 implemented standards and guidelines, powerful calculation

algorithms, extensive tools for object handling, outstanding 3D visualization and the very

user-friendly interface CadnaA is the perfect software to handle national and international

noise calculation and noise mapping projects of any size.

54. With its technical capabilities and its ease of use CadnaA represents state-of-the-art

technology. CadnaA is developed in C/C++ and communicates perfectly with other

Windows applications like word processors, spreadsheet calculators, CAD software and

GIS-databases. CadnaA includes a multi-lingual user interface and is successfully applied

in more than 60 countries all over the world.

55. CadnaA calculations are in line with the majority of available National and International

Standards. Here, ISO 9613-2 will be used as example. A-weighted sound pressure level

at the receiver point Lat (equivalent continuous A-weighted sound pressure level) is

defined by following equation:

LAT= PWL+ DI + DΩ – ADiv – Aatm – Agr – Abar – Amisc

56. Where:

Sound power level Pwl in dB, produced by the point source to a reference sound power of one picowatt (1pW).

Directivity index DI: deviation of the emission sound pressure level from the mean sound pressure level for directionally radiating sources in the considered direction related to all directions. For building radiation the calculation of the directivity index takes place in CadnaA with consideration of the self-screening.

Solid angle rate D (K0): index that accounts for sound propagation into solid angles ХОss tСan 4π stОraНТans

Attenuation due to geometrical divergence: ADiv: the geometrical divergence accounts for spherical spreading in the free field from a point sound source to the receiver:

ADiv = [20 ∙ lg (d/do) + 11] dB (7) d: distance from source to receiver; do = 1m (reference distance)

57. If no deviating frequency by the standard value is entered, CadnaA calculates 0.002 dB/m for 500 Hz.

58. Generally the emission levels can be determined from levels measured at specified distances by the equation. Equation enables to derive the dependency of the sound power level LW (PWL) from the sound pressure level Lp (SPL) measured in a distance R for point- line- and area sources in different configurations.


_____________________________________________________________________________


59. With CadnaA it is possible to determine the Sound Power Level of point sources (or

sources with dimensions small relative to the measuring distance) from measured sound pressure level Lp, the measurement distance and the sphere partition.

60. CadnaA is able to determine autonomously the required height of a noise protection wall/barrier which is needed to obey given maximum levels by means of iterative calculation. The optimization occurs for up to four evaluation parameters.

61. For the road projects the following national and international standards and guidelines are implemented in CadnaA:

- NMPB-Routes-96 (France, EC-Interim)

- RLS-90,VBUS (Germany)

- DIN

62. 18005 (Germany)

- RVS04.02.11 (Austria)

- STL86 (Switzerland)

- SonRoad (Switzerland)

- CRTN (United Kingdom)

- TemaNord1996:525 (Scandinavia)

- Czech Method (Czech Republic)

- NMPB-Routes-08 (France)

- TNM (USA)

- CNOSSOS-EU

63. In order to use the software, it was necessary to accomplish a number of studies to collect

all the information needed for modeling.


_____________________________________________________________________________


5.3 Modeling results

64. For the modeling of the existing noise level the following data were used: (i) the results of the 24-hr measurements of the existing noise levels at 2 points in the project zone; (ii) the data of the existing traffic analysis; (iii) strength and direction of the wind; (iv)maximum allowed traffic speed (speed limit), and (v) the type and quality of road pavement.

65. No exact information exists upon season vehicles on the project section. Proceeding from above, only existing, statistic data shall be applied for modelling stage. Traffic counts for the existing road have been conducted on two occasions. The first was in June 2017 and the second in October 2017. The results of the two sets of counts show some high percentage variations. The June 2017 counts did not cover a full 24-hour period and were conducted when an alternative route, the Vose – Khovaling road was still under rehabilitation so there may have been some diverted traffic using the Kangurt to Khovaling Road.

66. Figures 13-19 show the results of accomplished modeling in 6 settled areas adjacent to the project area. The modeling results are given in 2D format.

67. The detailed information about the noise impacts on each building at different stages of the project implementation, as well as in 2025 and 2033, is given in Annex 1. The given tables show the impact of noise both, during the day and at night.

68. The residential buildings and premises, which are located adjacent to the project area, are mostly one-storey. As for the buildings and premises housing small and medium businesses, they are mostly two-, three- or four-storey buildings. The mentioned business units are mostly concentrated two settled areas: Baljuvon and Kangurt.

69. Figures 19 and 20 show the impact of the existing noise on different floors of the buildings in Baljuvon settled area, adjacent to the project road.

Figure 19: Noise values during the day (City Baljuvon)

Figure 20: Noise values at night (City Baljuvon)

70. Figures 21 and 22 show the impact of noise on multi-storey buildings in the city of Kangurt adjacent to the project road, both, during the day and at night.

Figure 22: Noise values during the day (City Kangurt)


_____________________________________________________________________________


Figure 22: Noise values at night (City Kangurt)

71. As per the modeling results, despite the forecast suggesting that the number of vehicles will increase in the project zone by 3% annually, the existing (background) noise level is higher than the noise level to establish following the implementation of the project. This can be explained by the fact that at the given stage, the carriageway for vehicles is a ground road, while it will be asphalt-coated following the implementation of the project.

6. CONSTRUCTION STAGE

72. The dominant source of noise from most construction equipment is the engine, usually a diesel, without sufficient muffling. Only in a few cases noise generated by the process dominates (for example, impact pile driving, pavement breaking).

73. Noise levels during construction will vary depending on the activity, type and number of equipment, work schedule, duration of use and the distance from receptor. Construction in this analysis, first the noise level due to each piece of equipment, which is likely to be used in the construction, is calculated. Noise levels induced by the main road construction equipment considered in assessment are presented in Table 10. (Note: the values indicated in the table may differ depending on the brand of machinery provided/used by contractor). The list includes all equipment except vehicles and some minor pieces of equipment.

74. During the noise modeling in the construction phase, we assumed that 4 heavy equipment

would operate at the same time.

75. As per the modeling results, during the construction phase the noise level will much increase and will exceed the admissible level near most buildings and premises found adjacent to the project zone. The detailed information about the buildings where the noise level will exceed the admissible level is given in Annex 1.

76. At the same time, it should be noted that the noise impact will be a short-term one. Despite this, a number of mitigation measures are necessary to avoid the negative impact on the population resulting from the increase in noise level.

6.1. Mitigation at the source

77. Source controlis, ingeneral, the most effective form of noise mitigation and involves

controlling a noise source before it is able to emit potentially offensive noise levels.

Construction noise (exclusive of blasting) is typically generated by two source types: (i)

Stationary equipment; and (ii) Mobile equipment.

78. Less noisy equipment: One of the most effective methods of diminishing the noise

impacts caused by individual equipment is to use less noisy machinery. By specifying

and/or using less noisy equipment, the impacts produced can be reduced or, in some

cases, eliminated. Source control requirements may have the added benefits of

promoting technological advances in the development of quieter equipment.

79. Mufflers: Most construction noise originates from internal combustion engines. A large

part of the noise emitted is due to the air intake and exhaust cycle. Specifying the use

of adequate muffler systems can control much of this engine noise (Figure 23).

80. Shields: Employing shields that are physically attached to the particular piece of

equipment is effective, particularly for stationary equipment and where considerable

noise reduction is required (Figure 24). No table of figures entries found.

Figure 23: Muffler System Figure 24: Employing Shields

81. Aprons: Sound aprons generally take the form of sound absorptive mats hung from the

equipment or on frames attached to the equipment. The aprons can be constructed of

rubber, lead-filled fabric, or PVC layers with possibly sound absorptive material covering

the side facing the machine. Sound aprons are useful when the shielding must be

frequently removed or if only partial covering is possible.

82. Enclosures: Enclosures for stationary work may be constructed of wood or any other

suitable material and typically surround the specific operation area and equipment. The

walls could be lined with sound absorptive material to prevent an increase of sound levels

within the structure. They should be designed for ease of erection and dismantling.

6.2 Mitigation along the path

83. In some situations, such as in urban areas or on isolated sections of a project (tunnel

installation area), it may be beneficial and necessary to construct barriers adjacent to the

work area or at the right-of-way (RoW). These can take the form of natural shielding,

temporary shielding, and/or permanent shielding.

84. Temporary abatement techniques include the use of temporary and/or movable shielding

for both specific and nonspecific operations. Some mobile shielding is capable of being

moved intact or being repeatedly erected and dismantled to shield a moving operation. An

example of such a barrier utilizes noise curtains in conjunction with trailers to create an

easily movable, temporary noise barrier system.

6.3 Mitigation at the receiver

85. Mitigation at a receiver can vary in its complexity, ranging anywhere from relocating residents for a day to insulation of a building. Even after mitigation measures have been applied, the outcome may still be unpredictable with no guarantees that the implemented methods achieve expected results. Therefore, mitigation at the receiver should only be considered as a last alternative. However, there are cases where creative techniques have been successfully implemented.

6.4 Training Programs for Contractors

86. Require contractors to participate in training programs related to project-specific noise requirements, specifications, and/or equipment operations. Such training may be provided by agency or project management personnel, outside consultants, and/or equipment manufacturers or suppliers. For example, project personnel (or consultants assigned to the project) may train the contractor in the measurement of construction-related noise levels that may be required to meet the contract specifications.

87. In addition to the additional mitigation measures proposed by the Contractor, the latter

must observe the norms, which are common for the construction phase of any project.

Such norms are:

Use of non-faulty construction techniques and vehicles;

Implementing the noisy Works during the day as far as possible;

Running the vehicle drives at minimal speed.

7. OPERATION PHASE, 2019, 2025 AND 2033

88. In the operation phase, the noise modeling was done for the following phases: (i) following the completion of the project works, in 2019, (ii) in 2025 and (iii) in 2033.

89. The detailed information about the expected noise impact on each building and premise is given in Annex 1. The given Annex provides the forecasts of the expected noise levels both, during the day and at night.

90. As the tables given in Annex 1 show, as a result of the project implementation, the noise level at all buildings and premises will decrease by 3 Db on average and will get close to the existing noise level only by 2033.

91. As already mentioned, this is caused by the present-day road pavement. Presently, the project road is a ground road. The ground pavement of the road helps increase the noise level sharply. Under the project, the project road will have an asphalt pavement, what, as the practice evidences, reduces the noise level twice.

92. Figures 25 and 26 show the results of noise modeling in the operation phase on the buildings and premises in the city of Baljuvon near the project zone, in different years and along several sections of the project road.

8.CONCLUSIONS AND RECOMMENDATIONS

94. Based on the results of the 24-hour measurements in the Project zone and noise level

modeling results, we can make the following conclusions and recommendations.

8.1 Conclusions

1. The project zone crosses 6 settlements of different sizes: (i) Kangurt; (ii) Mlukon; (iii)

Khanabad; (iv) Khirob: (v) Baljuvon; and (vi) Shagmon. The buildings and premises in

the above-listed cities and settlements are located both, adjacent to the project zone

and quite far from it.

2. The principal noise source in the Project zone is traffic. The buildings in the project

zone and adjacent to it are mostly used for living. In addition, some buildings housing

small and medium businesses, are mostly small markets and catering objects;

3. Following the project implementation, the noise level at all buildings and premises will

decrease by 3 Db on average as compared to the baseline level and will get close to

the existing noise level only by 2033 as a result of replacing the present ground

pavement with an asphalt one.

4. Under the baseline measurements and modeling results, the noise level was within the

norm at all buildings and premises in the project zone besides some exceptions. In line

with the modeling results, for 53 of 755 buildings (7 %), the noise level exceeds the

admissible level, during the day and/or at night.

5. In the construction phase, the noise level increases and it will be higher than the

admissible level at 445 (58.9%) buildings during the day. However, the impact of noise

will be short-term and relevant mitigation measures will be developed within the scope

of the project.

6. In line with the noise modeling results, during the operation phase, the noise level will

not exceed the admissible level at either of the buildings, either after the project

implementation or in 2025 and 2033.

8.2 Recommendations

95. The following major recommendations were developed for the noise management process:

1. The Construction Contractor, prior to the commencement of the construction

activities, must develop and submit the Supervision Consultant a Topic Specific

Environmental Management Plan – Noise Management Plan for the construction

phase. The Plan must envisage all the existing technologies and best practice to

avoid occurrence of noise and/or minimize the noise level;

2. At the modeling stage, the maximum admissible speed is taken in line with the

requirements of the effective legislation of Tajikistan, under which maximum

admissible speed is 60 km/hr for small settled areas and is 40km/hr for large

settlement. Consequently, speed limit signs are necessary to provide along the

project road.

3. At the modeling stage, the value of increase of the present vehicle flow is taken

annual 3% proposed by the consulting company. If, as a result of the project


_____________________________________________________________________________


implementation, an increase in the vehicle flow exceeds the forecasted value,

additional studies will be necessary.

APPENDIX- L: SET UP AND MANAGEMENT OF CONTRACTORS

CAMP

1. Camp Set Up and Management Careful planning and a concern for health, safety and the environment are essential for good project management under the proposed project. TСО ωontraМtor’s field camps should provide adequate working, eating and sleeping arrangements for field personnel and should be appropriately equipped to encourage employees to work safely and efficiently. At the same time, camps should make as little impact as possible on the environment. Project managers have to allow sufficient time to secure the required permits and permissions before sites are opened. Consider the following factors when selecting a camp site to ensure safety and security of staff:

a) Time of residence: Will the camp be in operation for a field season or year round? b) Duration: Temporary or a permanent establishment c) Size of the camp (at each time of year): d) Accessibility: Transportation access may impact the site selection e) Required permits:

2. Risks and Hazards Associated with Contractor Camps

The following are the possible risks associated with the camp.

Slips, trips and falls caused by uneven surfaces, wet or icy ground, obstacles, poor housekeeping, poorly built steps, inadequate lighting;

Back injuries and strains caused by improper lifting and manual handling techniques, slips and falls;

Fires caused by improper fuel storage, fuel use, and fuelling practices; faulty heating equipment or failure to turn off equipment; exploding fuel tank; clothes draped above heaters or on electrical wires; failure to extinguish open fires or cooking fires;

Illnesses spread by contaminated water, food or sewage contaminated drinking water; Diseases spread by local insects, parasites, vermin and larger animals; Animal attacks caused by poor choice of camp location inadequate garbage disposal,

and poor camp hygiene; Carbon monoxide poisoning caused by poorly maintained heating equipment;

inadequate ventilation of buildings; misuse and/or lack of maintenance of motors and engines; not following procedures when working in confined spaces;

Electrocution, electric shock, or burns caused by inadequate or improper wiring, lack of qualified personnel to install or repair electrical equipment, and lack of adequate employee training;

Cuts, burns caused by spilled hot food or liquids, misuse of kitchen equipment, hot equipment (generators, heating stoves/ovens);

Injuries or occupational illness caused by exposure to hazardous materials; Damage from landslips caused by poor camp location.

3. Alcohol and Drug Policies

Contractors should have a clear and concise policy to address alcohol and drugs at project and camp sites. The policy should conform to regulations of the Government of Tajikistan. The Contractors should respect the wishes of local communities, especially when working in or

nОar a “МХustОrОН” МommunТtв. TСОrО sСouХН bО a provТsТon Пor ОmpХoвООs to sТРn oПП tСat tСОв understand the policy and regulations. Waste Management Proper waste management is fundamental to camp safety. Project management should determine how waste products are ultimately handled – whether they are recycled or subject to various treatment and disposal options. Depending on the regulations, it may be advisable to seek expert advice to develop a waste management program. It is essential to eliminate potential camp sewage discharge or spills that may contaminate surface and ground water, eliminate potential disease-causing organisms and smells from accumulations of waste deposits that attract wildlife, including vermin. General tips regarding waste management.

Secure required permits and follow all applicable regulations of the RT waste classification, management and disposal, including for any hazardous waste products that may be produced at the site.

Waste storage areas: All waste storage areas should have restricted access to limit entry by employees, the

public and animals. Provide fly-tight garbage containers in convenient locations. Maintain containers so

they do not become foul smelling, unsightly or breeding place for flies. Camp sewage: Treat and maintain camp sewage as appropriate for the site and size of camp. A proper sewage and/or latrine system is necessary to control potential water contamination, odors and diseases. Comply the following:

Construct and maintain all camp sewage toilets correctly; Prevent flies, insects, and rats from gaining access to waste materials; Prevent surface or ground water from entering the pit or vault; Prevent waste material in the privy from contaminating any water supply; Self-closing seat covers are advisable and should be in operation at all times.

APPENDIX-O. RECOMMENDATIONS FOR TENDER DOCUMENTS The physical works of project are being designed by an engineering consultant (SMEC) the PIURR who prepared the tender documents. Construction will be carried out by a contractor selected by international competitive bidding (ICB) in accordance with the ADB rules for procurement of works. The Bank's Standard Bidding Documents for Works have a specific format, and based on the well-known standard documents developed over the years by the International Federation of Consulting Engineers (FIDIC). As such, this Appendix provides guidance on environmental and social topics which should be considered for incorporation into the 43km Kangurt-Baljuvon-IVK Road contracts. In order to protect the sensitive environment, accelerate the flow of benefits and to establish a high quality example for other road projects to follow, it is recommended that the following points should be included in contract document: The Clauses are: 1. The Contractor shall follow the Updated IEE (UIEE) included in the Contract; 2. In order to ensure the compliance with proposed mitigation and monitoring measurements required under the UIEE, the Contractor shall closely liaise and coordinate with the Consultant's Environmental Safeguard Specialist. 3. Environmental Officers (at least qualified Graduate in environmental science/ engineer with relevant experience) as per field requirement shall be appointed by the Contractor. 4. The Contractor shall ensure compliance with the labor laws and pertinent occupational health and safety regulation of Tajikistan, and ADB. The Contractor shall ensure that all workers are supplied with and use the relevant protection safety equipment on the construction site. Abstain from employing child labor. 5.
