I. EXECUTIVE SUMMARY
A Overview 1. The Government of the Socialist Republic of Viet Nam (GOV) has requested the Asian Development Bank (ADB) to provide financing to facilitate investments to support the upgrading of roads proposed in the technical assistance (TA) Transport Connections in Northern Mountainous Provinces Project TA 7245 – VIE (TCNMP). The TCNMP proposes a comprehensive program to upgrade and rehabilitate 12 roads in six northern provinces with a total length of about 304 km in Ha Giang, Yen Bai, Cao Bang, Tuyen Quang, Lao Cai, and Bac Kan (Figure I.1). The executing agencies (EA) are the respective Provincial People’s Committee (PPC) of each province. The implementing agencies (IA) will be six separate provincial project management units (PPMU) that are already established in all provinces except for Yen Bai province, which plans to establish its PPMU within 2011. 2. The Project supports ADB's Viet Nam Country Partnership Strategy 2007 to 2010 and GOV's Socio Economic Development Plan (2006-2020) that identifies a lack of rural infrastructure in the northern mountainous region as a constraint towards effective poverty reduction. In Ha Giang province the Project will cover stretches of two provincial roads in the network. The Project road stretches selected for improvement are along TL176A and TL183. This report is the initial environmental examination (IEE) for the improvement of the relevant section of the Project roads in Ha Giang Province (Figure I.2). This IEE is prepared by the Ha Giang PPC to ensure that the Project road design, construction and operation will comply with the provisions of ADB's Safeguard Policy Statement 2009 (SPS). 3. The proposed road improvement works are within the right of way (ROW) designated for the Project roads but some construction may take place on land yet to be acquired depending on detailed designs. These areas were subject to rapid environmental assessment. Based on ADB’s Safeguard Policy Statement 2009 (SPS), ADB has classified the Project as Category “B” and requires the preparation of an IEE. 4. The objectives and scope of this IEE are to (i) assess the existing environmental conditions along and in the vicinity of the Project roads (ii) identify potential environmental impacts from the proposed road improvement works (iii) evaluate and determine the significance of the impacts; (iv) develop an environmental management plan (EMP) detailing mitigation measures, monitoring activities, reporting requirements, institutional responsibilities and cost estimates to address adverse environmental impacts; and (v) carry-out public consultations to document any issues/concerns that stakeholders may have on the Project and to ensure that such concerns are addressed in the project design and mitigation measures. 5. This IEE is submitted to ADB by the Ha Giang PPC and the final IEE report will be disclosed to the public through the ADB website and to the public in Viet Nam by the PPC and PPMU. The IEE will also be disclosed by the PPC to the Ministry of Natural Resources and Environment (MONRE) and provincial Department of Natural Resources and Environment (DONRE) and to the local authorities in Ha Giang province for review and identification of additional environmental assessment and environmental permits that may be required.
B Policy, Legal And Administrative Framework 6. The Project shall comply with requirements of ADB SPS 2009 and the GOV’s Guidelines on Implementation of Law on Environmental Protection 2006 (under Law on Environmental Protection 2005 as amended by Decree 21-2008). The Ministry of Natural Resources and Environment (MONRE) has delegated powers to DONRE to approve environmental assessments and MONRE will receive a copy of the environmental assessment before construction commences. However certain activities commonly associated with infrastructure projects such as quarry operations, extraction of gravel or discharge of waste water will also require permission from the relevant provincial level Page 1
authorities. PPMU will submit the IEE to DONRE and disclose the scale and scope of the Project to the environmental authorities in due course.
C Description of the Project 7. The rehabilitation and upgrading of TL176A and TL183 will involve some alterations to the roads width by 1 m or less in some places on either side to improve road geometry within the ROW. The ROW is different for each road but it is approximately 3 m from edge of the slope or embankment either side of the road base. This puts the ROW at least 6 m either side of the centerline even for the narrowest parts of the roads. There will be a need for limited resettlement and the resettlement pans will be accomplished by the Provincial Peoples Committee of Ha Giang (PPC) who will also carry out the required social interventions. 8. The lengths of the roads are approximately 29.2 km for TL176A and 34.6 km for TL183 (Figure I.2). The construction of the improvements to TL176A and TL183 should be straightforward but as yet there are no detailed designs for these works. The existing alignments go through several villages. Road TL176A will be upgraded to Vietnamese Standard VI (VN VI) and road TL183 will be upgraded to VN IV. For purposes of the conceptual design it is assumed that where slope cutting is necessary the roads will generally be widened on the uphill side creating a requirement to excavate spoil but there are limited opportunities to use this material as fill. Therefore spoil disposal will be significant but other construction impacts should be of a scale typical for a road upgrading project. 9. Bridges on the Project roads will be improved to accommodate vehicles in accordance with Viet Nam Code for Bridge Design (HL 93 and 22TCN -272-05) constructed as permanent concrete and steel structures. There are 2 bridges and 204 culverts that have been considered for improvement or reconstruction. 10. A joint coordination committee (JCC) for the Project will be established to coordinate and monitor the activities of the six PPMUs. The JCC will be chaired by the Vice-chairman of Bac Kan PPC and comprise Vice-chairpersons of the six PPCs. The JCC will retain an international project coordinating consultant (PCC) with environmental capability provided by a suitably qualified international and national environment specialists to assist the PPMUs. The PPMUs will engage national detailed design consultants (DDC), national contractors and national project supervision consultants (PSC) for upgrading and/or reconstruction of the roads. The target date for completion of reconstruction and upgrading is by end 2016.
D Description of the Environment 11. The climate is subtropical and the area is subject to heavy rainfall between April and October. The roads are fairly flat in some places but there are many undulating and steeper sections through the hill terrain. During rainy periods surface water on the road runs to the adjacent fields and canals and in the hills via crossing drainage structures and culverts. The mountainous area of Ha Giang Province provides the catchment for several rivers including Lo, Chay, Nhiem, Sao, Gam, Bac, and Mien. The rivers and their tributaries serve agriculture and domestic water supply. 12. The biological environment is dominated by agriculture. There are also several areas of biodiversity and conservation value in Ha Giang Province. Tay Con Linh, Phong Quang and Bat Dai Son, Phong Quang-Vi Xuyen and Cang-Bac Me are all more than 5 km from any of the roads under consideration. The Project Roads do not cross a National Park or Nature Reserve or Protection Forest and none of the land in the ROW is production forest or protected forest but the buffer zone of Du Gia Nature Reserve is about 2.5 km south and west of the Project Road 176A. The valuable ecological resources in the core areas protected for the natural habitats for rare or endangered species in Du Gia Nature Reserve is much farther than 2.5 km south and west of the stretch of Project road TL176A selected for improvement (Appendix B). The Project Road 176A crosses the Dong Van Karst Plateau Geopark (DVKPG) which is protected
Page 2
for it’s geological resources and scenic landscape created by the extensive area of karst mountain formations. 13. The local provincial environmental authorities have not identified any issue of additional interference with sites protected for their biodiversity for TL176A and TL183. There does not appear to be any direct interference with protected forests or the geological resources due t the small scale nature of the works and because the works will be within the ROW for existing roads TL176A and TL183. The social and human impacts to village life and impacts to social infrastructure will be of short duration and these have also been subject to detailed assessment in the Resettlement Plan. Cattle are kept along on the Project roads and other animals and birds near the roads are typical of those that tolerate disturbance by human settlement. There are a few large trees that will need to be avoided in the detailed designs but if cut, compensatory tree planting will take place. 14. Ha Giang is developing socially and has an improving economy with many home craft enterprises. Traditional shop houses are located at intervals all along TL176A and TL183 and ribbons of residential development are present throughout the settlement areas. The land around the Project roads is used for rice cultivation. Rain-fed rice paddies and cultivation of vegetable and cash crops, in some cases based on shifting cultivation, are more common in the hilly areas. As yet the rivers are not subject to heavy industrial pollution and there are institutional arrangements to control pollution in future. 15. There are no sites of cultural significance found close to TL176A and TL183. There are schools, hospitals and some places of worship within sight of the Project roads in some nearby villages. All will be set back from where the road works are currently planned to take place and no significant impacts are anticipated.
E Anticipated Environmental Impacts and Mitigation Measures 16. The potential environmental impacts will require mitigation measures to minimize the impacts in the design, construction and operational phases. The main issues relate to planning design of road structures and drainage and control construction impacts such as spoil and waste disposal, traffic interruption, noise and dust during construction. The buffer distance between the works on the Project roads and the nearest residential sensitive receivers is ample in most cases. should only be moderate disturbance to the surrounding areas from the works provided the EMP is implemented fully. 17. Starting at the detailed design stage and throughout construction the PPMU will retain a suitably qualified environmental and safety officer (ESO) and with the assistance of the PCC will ensure proper implementation of the EMP prepared for the project. PPMU with the assistance of the PCC will: (i) disclose the final Project road design to DONRE and ADB; (ii) check that the Project site works boundaries correspond with those disclosed in this IEE; (iii) prepare tender documents to include the EMP to ensure the contractors comply with environmental requirements; (iv) ensure environmentally responsible procurement and the acceptability of sufficient borrow sites for rock based materials agreed with DONRE; (v) plan spoil and waste disposal (vi) plan to preserve and avoid road side trees and compensate for trees that will be removed; (vii) confirm hydrological and drainage impacts of the Project and ensure detailed bridge designs take account of a 100 year return rain storm event; (viii) plan to minimize disturbance of vehicular traffic and pedestrians during construction (viii) take baseline water quality, air and noise samples before construction commences; and (ix) assist the contractors to orient workers on EMP provisions as well as health and safety aspects. The PPMU will also make a reassurance check with the responsible authority that there is no potential threat from unexploded ordnance (UXO) before works commence. 18. Construction impacts will mainly be from works to reconstruct the road base, repairing bridges, renewing culverts across streams, providing better crossing drains in embankments and repairing road embankment base courses, and surfacing works. The location for construction works will be well away from most of the nearest residential
Page 3
sensitive receivers (SRs) that are outside the ROW and in principle this should allow ample buffer distance to attenuate many potential nuisances. 19. The PCC shall prepare specific EMPs (SEMPs) during detailed design phase. These SEMPS will include (i) waste management and spoil disposal; (ii) temporary drainage; (iii) temporary traffic management; (iv) materials management; (v) erosion control; (vi) noise and dust control; (vii) utilities and irrigation reprovisioning; and (vi) workers and public safety. Contractors will be required to commit to implementing the Project EMP and the SEMPs. The SEMPs will be based on the EMP matrix presented in this IEE (Table VIII.2). PCC with conduct workers’ orientation on implementation of construction mitigation measures in the Project EMP and SEMPs and shall monitor the implementation of EMP provisions. Unsuitable soils, spoil and construction waste will be disposed of to sites approved by DONRE as agreed with local authorities and disposal will be monitored. Wastes will not be burned. The acceptability of the borrow and quarry sites for fill materials will be agreed with DONRE and corresponding required environmental permit or clearance will be obtained by the contractors prior to operation of such sites. Building materials will be obtained from sites approved by DONRE using local sources as practicable to minimize transportation and stockpiling of building materials. Work that will result to emission of high noise levels will not be undertaken at night in the vicinity of sensitive receptors. A qualified environment and safety officer will be identified by the Contractors before construction commences. Facilities for workers and public safety, construction site offices and worker camps will be regulated in line with the labor codes of Viet Nam. Complaints will be monitored and investigated and additional mitigation measures will be implemented, as necessary. The EMP will be updated by PCC if unexpected impacts occur. 20. The Project road stretches pass through agricultural areas and villages and small towns. The TL176A runs through the Dong Van Karst Plateau Geopark protected for its landscape and geological resources. The PPMU will co-operate with the Geopark’s management board to introduce mitigation measures during construction phase to avoid or minimize impacts to this protected area. The landscape and forests will be protected and mitigation measures have been included in the EMP to prevent further conversion or degradation of biodiversity and to provide enhancement where practicable. 21. Due to the distance to the nearest nature reserve and the small scale nature of the proposed road works, there are no measurable adverse impacts on critical or natural habitats that can be foreseen which could impair the biodiversity value or function of nature reserves or protected forest areas. The improvements to the Project road stretches are not anticipated to lead to a reduction in the population of any recognized endangered or critically endangered species and there will be no loss of valuable habitats that could compromise the host ecosystem. 22. The operation of the improved Project roads should have little effect on the surrounding environment and the introduction of the wider pavement can be expected to reduce air pollution from disturbed dust and noise from vehicles on the smoother roads. The improvement of the Project roads will be within the existing corridor keeping vehicles away from sensitive receivers such as residences, commercial premises and schools that are set back from the Project roads. Gaseous and particulate emissions from the expected traffic flows will be well dispersed road to be affected and there will be insufficient traffic to increase noise above the acceptable standards. The upgrading is likely to increase the vehicle speed but additional future traffic should be moderate and unlikely to create many community safety issues and overall the condition of the road facilities will be enhanced and driving conditions should improve. Routine safety measures, signage and road markings will be introduced to reduce driving risk further and will be verified at detailed design stage.
F Information Disclosure, Consultation and Participation 23. The stakeholder consultation process has disseminated information in advance on the upgrading works and the expected impacts and the proposed mitigation measures.
Page 4
The process also gathered information on relevant concerns of the community so as to address these in the project implementation stages. 24. The results indicated there was very strong support for the Project and the main environmental concerns were interference with connection to water and power supplies, construction noise and dust. Other responses are mainly concerns on prompt compensation for land acquisition and a wish for further consultation between the local people and the Project authorities as well as concern that compensation for land to be acquired by PPC should be fair. The environmental concerns raised by the stakeholders shall be controlled and minimized by thorough implementation of the EMP.
G Grievance Redress Mechanism 25. Existing arrangements for redress of grievances are through complaints to the Ward committees up to the District level and then through the PPC and back to PPMU. 26. Through a Grievance Redress Committee (GRC), PPMU shall promptly address affected people’s concerns, complaints, and grievances about the Project’s environmental performance at no costs to the complainant and without retribution. The GRC, which shall be established by PPMU before commencement of site works, shall be chaired by PPMU and shall have members from the contractors, ward and district committees, DONRE, local NGO, and women’s organization. Grievances can be filed in writing or verbally with any member of the GRC. The committee will have 15 days to respond with a resolution. If unsatisfied with the decision, the existence of the GRC shall not impede the complainant’s access to the Government’s judicial or administrative remedies. 27. The PPC through the PPMU shall make public the existence of this grievance redress mechanism through public awareness campaigns. PPMU shall also provide telephone numbers for complaints and these shall be publicized through the media and numbers placed on the notice boards outside the site and suggestion/complaints boxes will be placed outside the construction camps and yards. Locally affected people will still be able to express grievances through the ward or district committees and these would be referred to PPMU through the usual channels in those committees.
H Environmental Management Plan 28. The institutional requirements and responsibilities for various stakeholders including the EA, JCC, PCC, PPMU, DDC, PSC and contractors have been identified. The Project EMP as well as the SEMPs will be used as a basis for an environmental compliance program. The EMP was compiled by close reference to best practices and in line with SPS. A suite of mitigation measures has been proposed and the IEE concludes that the impacts will be manageable if the mitigation measures spelled out in the EMP are implemented thoroughly. Any conditions of the environmental clearance from DONRE and any subsequent licenses and approvals from local authorities will also be included in the environmental requirements for the Contractors in the compliance program. The requirements of the IEE, Project EMP and SEMPs will be included in the contracts. The effective implementation of the design and construction stage mitigation in the EMP shall be audited by PPMU, PCC and ADB as part of the loan conditions. The main monitoring of the contractor’s environmental performance on implementation of the SEMPs and various provisions of the Project EMP will be done by PPMU assisted by the PCC. If this is done effectively the impacts can be controlled well within acceptable limits. 29. PPMU with assistance from PCC shall: (i) update the EMP during detailed design phase should there be additional environmental impacts not identified in this IEE and for which appropriate mitigation measures have not been included in the EMP; (ii) prepare a new or supplementary environmental assessment report in compliance with SPS if there are any additional components or changes in the Project such as specific location/alignment, among others, that will result to adverse environmental impacts and are not within the scope of the environmental assessment report approved by ADB. The
Page 5
above documents shall be submitted by PPMU to ADB for review and clearance prior to implementation.
I Conclusion and Recommendations 30. The Project construction is restricted to areas within the ROW as far as can be ascertained at this stage. This IEE study was carried out when the Project roads upgrading work was at the conceptual stage of design during the TA 7245 REG. Secondary data and preliminary observations and ambient environmental baseline surveys were used to assess the scale of environmental impacts and public consultation and site reconnaissance were carried out in order complete the environmental assessments in a comprehensive manner and recommend suitable mitigation measures. The impacts from construction and operation will be manageable and no insurmountable impacts are predicted, provided that the EMP is included in the contract documents, and the EMP provisions are implemented and monitored to the fullest extent. In the event that any design details change the locations or scope of the proposed works the environmental assessment and EMP shall be reviewed and revised accordingly. PPMU shall ensure that the EMP is included in the contract documents.

II. POLICY AND LEGAL FRAMEWORK
A Environmental Regulatory Compliance 31. The environmental regulations of GOV for environmental assessment rules are set out in the Guidelines on Implementation of Law on Environmental Protection 20061 (under Law on Environmental Protection 2005 as amended by Decree 21-20082) that requires environmental assessment (in the form of an EIA) for listed projects. MONRE has delegated powers to DONRE to approve the environmental assessment for provincial projects and MONRE will receive a copy of the environmental assessment before construction commences. In this case the environmental assessment will be the IEE prepared for ADB. Therefore PPMU will submit the IEE to DONRE Provincial Environmental Protection Service in the province to disclose the scale and scope of the projects to the environmental authorities in due course and as required under SPS. In Viet Nam the environmental assessment process is established and the rules, regulations, procedure and processes for environmental impact assessment of development activities have been reviewed under decree 80/2006 ND-CP. The rules and guidelines on environmental management have been amended under decree 21/2008 ND-CP (February 2008). The main decrees and statutory instruments of relevance to this IEE are: i) Decree 21-2008-ND-CP of the Government of the Socialist Republic of Viet Nam. on Amendment of and addition to a number of articles of Decree 80-2006-ND-CP dated 28 Feb 2008 providing detailed regulations for implementation of the Law on Protection of the Environment. ii) Decree 80-2006-ND-CP of the Government of the Socialist Republic of Viet Nam. of the Government dated 9 Aug 2006 providing detailed regulations and guidelines for implementation of some articles on the Law on Environmental Protection. iii) Viet Nam Environmental Protection Law, amended in 2005, approved by the National Assembly on 12/12/2005, validity from 01/07/2006. iv) Governmental Decree No. 81/2006/ND/CP dated 09/08/2006 of the Government On instruction for fines for breach of Environmental Protection Law’s implementation. v) Circular No. 08/2006/TT-BTNMT dated 08/09/2006 of the Ministry of Natural Resources and Environment providing instruction of environmental strategic assessment, environmental impact assessment, and environmental protection commitment. vi) Viet Nam standards on environment protection (TCVN and QCVN) from 1995 to 2010. vii) Government Decree N0.121/2004/ND-CP dated 12/05/2004 providing the regulations on settlement of violations on environmental protection (in replacement of the Decree No 26/CP dated 26/04/1996). 32. Pollution standards prescribed for the protection of the environment are described in the Law on Environmental Protection (and the TCVN and QCVN standards as amended).
1 Guidelines on Implementaion of Law on Environmental Protection 2006 – 80/2006/ND-CP require EIA for new construction of Grade IV roads and for upgrading of roads from Class I to III. Upgrading of roads that are Class IV or V to Class III is not specifically mentioned. The EIA has similar scope and content to IEE for ADB. 2 Decree 21-2008 28 February 2008 - Amendment of and addition to a number of articles of Decree 80-2006- ND-CP of the government dated 9 August 2006 providing detailed regulations for implementation of the Law on Protection of the Environment.

The following standards will be referred to for ambient environmental monitoring of the Project: QCVN 08:2008/BTNMT (surface water quality), QCVN 05:2009/BTNMT (air quality), and TCVN 5949:1998 (noise). Certain project activities commonly associated with road improvement such as quarry operations, extraction of gravel or discharge of waste water also require licenses that are issued at the provincial level by DONRE and Provincial Peoples Committee offices (PPC) depending on the duration and scale of those activities. PPC offices are the authorities to decide on the permit requirements at the provincial level. 33. In Viet Nam the environmental assessment process is established but the rules, regulations, procedure and processes for environmental impact assessment of development activities have recently been reviewed under decree 80/2006 ND-CP. The rules and guidelines on environmental management have been amended under decree 21/2008 ND-CP (February 2008). 34. PPMU/PCC will review the IEE at the detailed design stage in the light of future developments and forward required revisions of documents to DONRE and ADB. The EMP will be updated by the PCC at the detailed design stage should there be additional environmental impacts not identified in this IEE and for which appropriate mitigation measures have not been included in the EMPInternational Conventons 35. Viet Nam is a party to several international conventions that are relevant to environmental management (Table II.1). None of the conventions has any direct or specific relevance for this IEE as the Project does not encounter any areas of environmental sensitivity covered by the conventions.

III. DESCRIPTION OF THE PROJECT
A Background 36. The existing road infrastructure needs to be improved because the standards and conditions of many of the roads in Viet Nam are inadequate to meet rapidly growing demand for efficient travel. This situation limits national development and economic growth. 37. The existing conditions of the Project roads vary and are good in some places but only fair to poor in some places. The road is sealed in some sections and earthen shoulders are often in poor condition. Some of the bridges are in poor condition and have wide holes in places which are repaired improperly from time to time. The culverts are in fair condition but some require major upgrading and repair. 38. The JCC will engage a project coordinating consultant (PCC) who will assist the JCC and the PPMUs to manage detailed design and supervision of construction. Procurement at the provincial level will be using project detailed design consultant engineers (DDC) who will be responsible for detailed design. It is assumed that the PPMU will undertake the project construction supervision (possibly assisted by construction supervision consultants). Reconstruction and upgrading will be completed by end 2013. The PPMU in Ha Giang Province (PPMU) will engage the DDC and for purposes of this IEE it is assumed that there will be a conventional NCB bidding to secure contractors for upgrading and/or reconstruction of the road. Detailed design, bidding, securing contractors and upgrading works are proposed to take place over a two year period between 2011 and 2013.
B Existing Road 39. The sections of the existing roads due for upgrading connect several parts of Ha Giang Province. The current widths and proposed widening are summarized in Table III.1. At it’s northern end TL176A connects from the junction of National Highway 4C and runs 33.8 km southwards to Coc Pang at the northern edge of the Du Gia Nature Reserve. Road TL183 connects from the junction of National Highway 2 and runs more than 50 km northwest towards Bang Lang (This road runs on to join with provincial road 279). The major portion of the traffic on these roads consists of motor bikes (more than 80%) with a few cars, trucks and public motor vehicles. Some trucks carrying people as well as goods in and out of the area. Traffic flows counted in September 2009 resulted in 436 (on TL176A) and 734 (on TL183) vehicles per day3.

40. The existing alignments pass by many villages and isolated settlements. The roads are fairly flat in many places and then undulating with some steeper sections through the hilly terrain.
C Proposed upgrading 41. The Project roads TL176A and TL183 require rehabilitation and upgrading to Class VI and IV respectively. This will involve some alterations to the width by 1 m in some places to improve road geometry. The ROW for these roads is defined as 3 m from the toe of the embankment slope (below) or 3 m from the top of the cut slope (above) the road. In most places therefore the existing ROW either side of the centerline, is ample for the proposed rehabilitation works (Figure III.1 and Appendix 1). The works for TL176A and TL183 will therefore take place within the existing road corridor and no significant impacts are expected outside the road corridor. However to get a better road geometry some resettlement and minor land acquisition may be involved in some locations, subject to detailed design. The proposed geometric design standard and widening is shown in Table III.2. Figure III.2 shows typical cross sections for the proposed road standards.

The road works will include (i) excavation and reconstruction of the embankment, (ii) reconstruction of one carriageway (3.5 to 5.5 wide) plus hard shoulders; (iii) repair and reconstruction of bridges (iv) ensuring drainage and access near villages and at other key areas is unimpaired by extension of numerous culverts; (v) upgrading road drainage and (vii) installing slope stabilization and bioengineering measures, landscaping and accessories. Compensatory planting will also be required for any trees that are removed although this is not expected to be a major task. There will also be waste disposal issues for the works as there will be a surplus of cut materials in many areas where these materials cannot be reused on the project. Total cut materials are estimated to amount to about 353,258 m3 of which about 30% will be rock cutting. However the rock is grade 3 and grade 4 and can be excavated by powered mechanical equipment and there should be no need for blasting. Some of this material may be used as fill for the embankment to offset the need to extract fresh rock based materials from quarries and borrow pits. This would reduce the requirement for rock based materials for embankments, currently estimated at 161,289 m3 (Table III.3). 43. The works are generally expected to take place within approximately 7 m of the centerline of the alignment subject to detailed design (allowing about 3 m temporary working space either side).

E Implementation Schedule 45. The implementation schedule for the Project has not been worked out in detail by the SC and potential bidding contractors have not yet been identified. However in principle it is intended to start the detailed design phase in 2012 and the Project works in all provinces will commence in 2013 and last until 2016. The likely commencement and duration of the
Page 13
Project works may vary in each province and will depend to a large extent on the duration of the detailed design phase (Appendix D).

IV. DESCRIPTION OF ENVIRONMENT
A Physical Environment
1. Meteorology and Climate 46. The climate in Ha Giang is subtropical and influenced by the annual south west monsoon. There are two seasons. Dry season starts from November and lasts until March. The rainy season is between April and October. During the dry season no rain may fall for several months and it is cooler. The rainfall varies and the average precipitation is about 1,200-1,800 mm. About 73% to 81% of the rain falls during the period from May to September. The yearly average temperature is about 230C, rising to a maximum of 330C during May and August. Main direction of wind is from the South – East. In winter, wind direction is from the North – East (up to 20 % of the time) bringing cold air from China.
2. Topography, Geology, and Soils 47. The topography of Ha Giang Province is mainly mountainous, with elevations above 500masl typically characterized by steep terrain, narrow river valleys, and low agricultural potential. This mountainous landscape extends across most of the north of the country, except for the plain of Dong Van. Ha Giang is mostly rocky mountains. Together, the alluvial plains and river terraces cover only about 20% of the land area. Large proportion of the mountain area is limestone karst and the rest is for other types of rock including granite. Soils along the rivers’ banks are mixtures of silt clay and stone particulates that have been flushed by run off and precipitated from the water. These soils are poor in organic matter. In paddy terraces, narrow hill valleys soil quality is greatly improved as agricultural cultivation is common. Waterlogged areas with muddy layers and flooded grasses are sometimes seen in small areas. 48. In general the whole province is divided into three parts as follows: The northern part with high altitude includes many high mountains and narrow valleys formed of limestone and metamorphic rocks. The western part includes high mountains formed of granite and its weathered products. The low-mountain that includes low hills and some large plains formed of shale and schist overlain by a yellow soil cover of 0.8 to 2.0 meters. 49. The Project roads are in the biophysically diverse northern mountainous highlands of Viet Nam. The north parts of Viet Nam have encountered major earthquakes and Ha Giang areas have also been subject to moderate seismic activity in the recent past but there is no record of recent volcanic activity in the mountains. The steep mountainous slopes, with their moderately thin layers of soils, are particularly prone to erosion when vegetation is removed and soils are exposed to rainfall and surface water flows. Thus, water quality in the mountain streams and rivers can be rapidly degraded when soils are eroded and flushed in to them, and result increased turbidity that reduces water quality for aquatic life and domestic and livestock consumption. Heavy rainfall is responsible for deteriorated sections of the provincial and rural roads. The Project roads pass through sedimentary limestone material. In between these karst ridges and slopes are recently deposited gravels and silts in narrow river valleys. However soil type should have very little bearing on the implementation of the works.
Page 17
3. Surface and Groundwater 50. The mountainous area of Ha Giang Province provides the catchment for several rivers including Lo, Chay, Nhiem, Sao, Gam, Bac, and Mien. The rivers and their tributaries serve agriculture and domestic water supply. The water flow varies between seasons from 2-10 liters per second (l/s) in the dry season to about 50 to 400 l/s in the rainy season. Water level also varies by 2 to 2.5 meters between seasons. In the dry season it is difficult for people living in mountainous areas to get enough water for their daily requirements. 51. Road TL176A runs at some distance along the valley of the Nam Lang stream, a small branch of Gam river. 52. Road TL183 follows the valley of the Khuoi Luong River from Binh Tong and crosses the river three times at Km2+558, Km12+893 and Km24+589 but is generally at a distance of more than 50m only coming within 25 m at about Km3+850 and Km16+600. After Km34 the road passes over a crest into the valley of the river Ngoi Giang, crossing that river at Km35+580, Km39+172 and Km43+791. Road TL183 also comes within 25 m at of the river at about Km40+100. Road TL183 run alongside the Chung and Con rivers at a distance of several hundred meters for most of the way from Vinh Tuy to Yen Binh. There is an intersection of Chung, Con and Bac rivers at a location about 4km to road TL183. After this intersection, there is an extended branch of Bac river across the road TL183 at Bang Lang village. Other smaller rivers run nearby road TL183 before the confluence with Con and Lo river at Vinh Tuy river intersection. 53. The rivers and streams are an important resource to the people in the project area. River flows are the highest from April to October. Most of the streams and creeks discharge all year round carrying high sediment loads, depositing large quantities of gravels and sands in the lower reaches. During the wet season some of the bridges and culverts are regularly inundated, cutting off roads and villages. The area around Mau Due, Du Gia has limestone caves and subterranean rivers travel through the rock formations. 54. The area provides a wide range of aquatic resources for subsistence and trade, as well as water for drinking, bathing, and crop irrigation. In addition, these rivers form local transportation routes and have potential for local small hydropower stations. There are not many navigable rivers in the project area and transportation is mainly reliant on the roads. 55. None of the rivers near the Project roads are subject to industrial pollution but there is a number of newly developed small workshops scattered alongside the roads. Some mines are in operation mostly for limestone and/or gemstone exploitation. Bamboo processing and saw mills are also present on the banks of the rivers that will affect the water quality in future. The nearest other industry is the Ha Giang industrial park, several tens of km from the project roads. 56. Domestic water supply is generally obtained from wells within the boundary of properties or uphill streams and river water is used for irrigation ad livestock. Therefore B1 is the appropriate standards for comparison purposes. Water quality monitoring was undertaken at 9 locations on Project roads in Ha Giang. The results are presented in Table IV.1.

57. In some residential areas, surface water may be contaminated by domestic wastes as levels of oil and grease in almost all water samples collected from Ha Giang exceeded the standard for total oil and grease in surface water (QCVN 08: 2008/BTNMT, column A1). The explanation may be high levels from domestic sources from food and cooking waste discharged to streams and that many of the sampling points are not in big streams or rivers but only in small water ways. In addition there is the local custom of washing motor bikes in the nearest stream which will cause oily residues to accumulate. The concentrations of oil and grease also exceed the limits allowed for surface water of agricultural usages. (QCVN 08: 2008/BTNMT, column B1). Beside, the levels of oil and grease, water analysis indicates the samples are still within the limits allowed for surface water of agricultural usage. (QCVN 08: 2008/BTNMT, column B1). 58. Groundwater is abundant in Ha Giang territory. People in urban and low-mountain areas are popularly using groundwater in shallow wells for domestic purposes. However, due to the structure of geology here, it is not so easy to dig a well for ground water. Beside, intensive use of the water is lowering the water level in shallow wells in built up areas. Ground water in Ha Giang has high hardness and total dissolved solids and needs to be treated before use for daily activities. Thus, many people in Ha Giang still rely on surface water sources and/or water leaching from rocky mountains.
4. Air Quality 59. Air quality monitoring was undertaken at 14 locations on Project roads in Ha Giang. The results ate presented in Tables IV.2. In general, air quality levels are within acceptable limits of Vietnamese environmental standards. The gaseous pollutants of
Page 19
carbon monoxide (CO), sulphur dioxide (SO2), nitrogen dioxide (NO2) from traffic appear to be well dispersed in the open terrain and there is potentially adequate dispersion in the wide main streets of the towns. Air quality appears to be generally acceptable. The exceptions are dust concentrations. Dust in many analyzed samples exceed the Viet Nam standards. This is understandable owing to the difficult situation of the transportation system in the province. All existing roads in the project area are of poor quality. Traffic vehicles find it difficult to move along the roads with weak foundations and broken surface pavements. Engines must run with high capacity and of course make more noise. Dust arises as traffic passes over unsealed shoulders of roads in many places making its high concentration in the air over the bad roads. 60. The areas near the towns at Mau Due, Du Gia, Minh Ngoc, Hoang Su Phi, Vinh Tuy and Yen Binh have more potential sources of atmospheric pollution mainly from domestic sources but these are not making significant impacts on air quality based on observation. These areas are more polluted due to significant town development as well as emissions from a few modest industrial establishments. The othe source of air pollution is dust arising from ground or soil disturbance. Dust concentrations will be higher, if only intermittently, within about 10m of the Project roads when dust rises from the shoulders as vehicles pass, although dust levels are not high enough to obscure vision significantly, based on field observations. The Viet Nam criteria currently set by the MONRE or the standards set by World Bank will be used for the assessment whichever is stricter.

5. Noise 61. Noise from vehicles is not a concern in the areas around the Project roads at present as traffic is confined to occasional vehicles. Noise levels are within acceptable limits of Vietnamese standards and WHO guideline. There is no criterion for road traffic noise in Viet Nam therefore the World Bank ambient noise criteria will also be applied. The World Bank applies an ambient standard of Leq55dB(A) for residential areas, hospitals and schools. Where the background exceeds the ambient standards the World Bank criterion is background +3dB(A). The Viet Nam ambient standards are Leq50dB(A) for residential areas, hospitals and schools and Leq60dB(A) for residential areas. Measurements of background noise were taken as 1hour LeqdB(A) at more than one location on each road. Background noise ranged from Leq45.3dB(A) to Leq53.0dB(A) with traffic. Therefore in the settlements and towns where traffic runs throughout the day the Viet Nam criterion of Leq50dB(A) for school and hospital sensitive receivers is potentially exceeded but the Leq60dB(A) criterion for residential sensitive receivers is not exceeded. As some of the Viet Nam criteria are exceeded at some times of the day it is recommended that in order to make a consistent assessment for all locations the existing World Bank criterion of background +3dB(A) will be applied in the assessment. The Viet Nam criterion of Leq40dB(A)1hour can be used for nighttime. However there is a general presumption that there will be no night time working except in exceptional circumstances.
B Biological Environment
1. Agriculture 62. Rice is the staple food of the Viet Nam People but in the cultivated areas around the Project roads there is only a limited portion of the land area suitable for wet-paddy cultivation due to the project area’s terrain. Large wet-paddy areas are found in many of the project areas but rain-fed rice fields are also common. Although rice is the staple food but only a limited portion of the land area is suitable for wet-paddy cultivation. Rain- fed rice paddies are also common and swidden rice cultivation is also practiced and vegetable and cash crops are produced as a substitute for rice deficiencies in many areas based on shifting cultivation. In addition to rice cultivation, a number of vegetable and cash crops are produced on a more commercial basis and as a substitute for rice deficiencies. In some cases, these are produced based on shifting cultivation. These crops include soya beans, cassava, green beans, peanuts, job’s tear, sesame, corn, teak, mulberry fiber, and a variety of fruit trees. People maintain vegetable gardens near streams and riverbanks and plant fruit trees near their house to supplement diets and to generate cash income. A variety of vegetables are grown such as cabbage, cucumbers, tomatoes, lettuce, chilly eggplant, and pumpkin.

63. Only about 19% of the total land area is classified as arable Table IV.3). The forested land area has declined significantly since the 1970s as a result of logging and slash-and-burn farming. Cash crops, mainly tea and nut are also grown. Herbal medicinal plant cultivation is also common practice of the minority peoples for self medication and market sale. 64. Some of the valleys have good agricultural potential. Despite these significant areas of good agricultural potential, income levels are very low and people are vulnerable to land degradation, declining crop yields and low incomes limit the capacity of households to obtain food.
2. Forestry 65. The land for 6 m either side of the Project Roads centerline is declared as the ROW (Figure III.1). The Project roads do not cross a National Park or Nature Reserve or Protection Forest and none of the land in the ROW is production forest or protected forest. The lands adjacent to the ROW (more than 6 m from the roads) are mainly agricultural land. Production forests in some areas are allotted to individual households (FPD 2010, Appendix B) but they are mostly several kilometers (usually more than 3 km) from the Project roads. The production forests are plantations where residents plant certain tree species which are harvested later. Popular trees for planting include acacia, casuarinas, cajput, eucalyptus, and chinaberry but the most common is mo or “fat” tree (Mangleitia glauca). Trees within production forest areas with land use title can be cut and will probably go for local use. If for some unexpected reason the Project roads’ alignment is changed and trees need to be cut for the upgrading of project roads there will be a need for the design consultants (DDC) to inform the forest authority so they can plan, mark and cut them first. 66. The local production forests are managed by the Forest Protection Department (FPD) in the Provincial Office of Department of Agriculture and Rural Development (DARD) according to the instructions and quotas for cutting and planting received from Ministry of Agriculture and Rural Development (MARD). The production forests that are outside the ROW are degraded and not that densely vegetated with mature trees but mainly small-diameter trees, bamboos and shrubs. Local officials indicated that trees can be cut with permission form the forest authority who will mark the trees and areas of bamboo for cutting. Bamboo cutting is regulated by the villages under quotas. There is good cooperation locally with the villages and the forest authority is notified of sales and the authorities levy charges for the forest products that are cut. 67. The local forestry officers in Ha Giang could not provide any detailed information on the location or species composition of the nearest production forest or protected forests. Timber extraction is generally local small-scale/saw-mill production of timber for local construction purposes. 68. No other records of the species composition or the boundaries of the forests could be identified but the forestry officials have indicated that much of the standing crop is bamboo and other small trees and shrubs. Planted specimens of bamboo, acacia, pine, cajuput, linh and cedrela are apparently the most common nearest the Project roads. The chief officer of FPD in Ha Giang indicated that the widening of the roads is not a
Page 22
concern to FPD because the proposed road works are modest and the roads has been in place for many years.
3. Fauna and Flora 69. The human impact on the vegetation is most pronounced in the areas where grasslands created by numerous cycles of forest clearance for agriculture and their reversion to fallow gradually transformed the forest to short grassland with secondary regrowth forest. 70. In 2007, the total forest-cover of Ha Giang province was 301,182.93 ha (approximately 38% of the province’s area). This includes 80% natural forests and 20% planted forests. At present, about 84,326 ha are protected river-head forests and natural reserves protected by policies of national and local governments. The forest ecosystems have a high biodiversity and contain many valued and endangered species protected by law in Vietnam. 71. There are several areas in Ha Giang Province that have been considered for protection for their biodiversity and conservation value. Tay Con Linh, Phong Quang and Bat Dai Son, Phong Quang-Vi Xuyen and Cang-Bac Me are all more than 5 km from any of the roads under consideration in this Project. Du Gia Nature reserve is about 2.5 km south west from the southern end of Project road 176A.
4. Don Van Karst Plateau Geopark 72. The whole of Project road 176A is within the Dong Van Karst Plateau Geopark, an area promoted internationally for landscape and geological significance. The Dong Van Karst Plateau Geopark was established in 2009 by Decision 4844/QD-UBND and the Management Board was also set up at that time decisions 4845&6/QD-UBND (all dated 19th November 2009). DVKPG was recognized by UNESCO in 2010. 73. Project Road TL176A is settled for all its length and it runs through a series of small villages. In between the villages there are agricultural fields in flatter areas in between the limestone karst outcrops and a few areas of trees planted on the hills for harvesting later. The vegetation near the road is mainly grass, ferns and shrubs with agricultural crops in the fields and a few scattered trees. 74. The sensitivity of the DVKPG to environmental change as a result of the Project road stretch TL176A needs to be considered. The location and proximity suggests that there could be direct, indirect or induced effects from the Project works but DVKPG Management Board (DVKPGMB) did not indicate any concern in this regard and they consider the protected area may not necessarily be sensitive to direct, induced or indirect Project road impacts because there is only modest widening to an existing road. 75. Consultations with DVKPGMB did not indicate any current problems with any illegal activities affecting the geological resources. The extraction of raw materials near the project road will be controlled because all of the Project road is within the DVKPG but there is no wholesale moratorium on such activities in the DVKPG. Rather, DVKPGMB expect to be consulted and permission must be obtained from the DVKPGMB before any borrow pits are opened up and before worker camps and disposal sites are selected because landscape and visual impacts should be avoided. 76. The DVKPGMB did not see the need for any project specific mitigation measures to protect the DVKPG resources but routine controls on worker camp operations, opening up borrow pits and worker camps and disposal sites should be included to prevent damage to DVKPG resources. These measures are included in the EMP in addition to the normal administrative requirements from DONRE and agreements with local district authorities and commune PPCs that PPMU must obtain before work can start.
Page 23
77. It is expected by DVKPGMB that in principle all waste materials must be removed from the DVKPG but this may not be practical in all cases. Therefore DVKPGMB shall be consulted in advance during the detailed design stage and again before bidding commences in case the PPMU wishes to set up any project related facilities in areas of DVKPG. DVKPGMB must approve in advance all project facilities to be located in the DVKPG and may also require additional mitigation measures to avoid project impacts especially in areas which are potentially sensitive to geological landscape and visual impacts. 78. However overall DVKPGMB indicated that because the Project road has been in existence for a long time there would appear not to be any major opportunity for induced impacts due to possible increases in uncontrolled access for exploitation of DVKPG resources caused by the improved road conditions due to the Project. However as DVKPG is recognized by UNESCO the DVKPGMB must be notified about the project in advance in due course. DVKPGMB do not envisage any difficulties in obtaining UNESCO concurrence for the Project road but it will be necessary to compile a report for UNESCO in advance. Hence DVKPGMB must be informed and consulted as soon as possible in the detailed design phase so that the requisite report can be compiled for UNESCO. No additional measures were requested by DVKPGMB. This seems reasonable given that there are already other local statutory and guideline controls in operation by DONRE and the local authorities. 79. The chairman of DVKPGMB indicated that they did not have any in principle objection to the Project road (Appendix D) and the widening of the road was not a concern to DVKPGMB because the roads works were modest and the road has been in place for many years before the DVKPG was declared.
5. Du Gia Nature Reserve 80. The end of Project road TL176A is about 2.5 km from the area known as Du Gia Nature Reserve (DGNR) that has been identified for conservation, due to its biodiversity. DGNR is also recognized as an Important Bird Area by Birdlife International. 81. The southern stretch of road TL176A passes roughly north to south near the Du Gia Nature Reserve but this is not the Project road stretch (Figure IV.3). The road TL176A was in place before the special forest use was declared. 82. In 1993 the Provincial Peoples Committee of Ha Giang issued Decree No 137/UB- QD to establish and develop Special Use Forests in the province including Du Gia4. The Du Gia (Du Gia-Yen Minh) Nature Reserve was identified in 1994 by Decision 647/QĐ, dated 24th November 1994, by Ha Giang PPC. 83. According to the investment plan, originally the total area of the proposed nature reserve was 24,293 ha, comprising a strict protection area of 7,652 ha, a forest rehabilitation area of 14,294 ha and an administration and services area of 2,347 ha. In addition, there was a buffer zone of 19,700 ha. 84. An investment plan was prepared in 1994 and approved by PPC of Ha Giang (PPC) and subsequently by MARD and a nature reserve management board was established with four persons following Decision No 647/QD-UB of PPC. The DGNR management board is chaired by the provincial FPD. Location, management and resources are presented in Table IV.4 (source MONRE 2010). 85. Biodiversity surveys of DGNR carried out in 2000 recorded 61 bird species including the globally threatened beautiful nuthatch Sitta formosa. Further rapid biodiversity
4 Sourcebook of Existing and Proposed Protected Areas in Viet Nam, IUCN – Bird Life International 2004.
Page 24
surveys conducted by BirdLife International (May 2002) recorded an additional 55 species. Because of its importance for beautiful nuthatch and biome-restricted species, Du Gia qualifies as an Important Bird Area. 86. DGNR was also confirmed to support a significant population of Tonkin Snub-nosed Monkey Rhinopithecus avunculus. This globally critically endangered species is endemic to northern Vietnam, and the population at Du Gia is believed to be one of the largest remaining. DGNRMB indicated that the home range for Tonkin Snub-nosed Monkey in DGNR is about5 km south west of the end of the project road, 87. The Ha Giang FPD indicated that the DGNR core zone and buffer zone boundaries have subsequently been modified and reduced to exclude many agricultural areas and include other areas of important and improving habitat. 88. Based on field inspection and maps obtained in February 2011, DGNR buffer zone is about 2.5 km from the start of the project road at its nearest point.. The protected habitats which are much further south west are where the rare species are believed to range and these core areas are well away from the Project road. Figures IV.1 and IV.3 are based on the map provided by the FPD. 89. Information and maps received from Ha Giang FPD indicate that the DGNR has been included on the provincial and district zoning maps. The edge of the buffer zone for Du Gia Nature Reserve is confirmed by Ha Giang FPD as shown on the land use map for the commune (2007) and is be managed by the Ha Giang FPD. The current boundary is shown on Figure IV.3.

90. The road TL176A runs south from Pho Bang International Border Crossing (about 45 km) to Mau Due and then Lung Ho for several tens of kilometers before running directly through the centre of the Du Gia NR. The section of Project road 176A is not
Page 26
within the area of Du Gia Nature Reserve as confirmed by FPD. The origin of the Project road section for improvement commences several kilometers north east of the Du Gia core area. The FPD officials have commented that the core zones for protection are much further south and west than the Project Road 176A. The FPD officials did not express any concerns for illegal logging or hunting in the areas around Project road 176A as there is very little habitat remaining in these areas. The Deputy Manager of Resource Management Department of DONRE in Ha Giang has also commented that there are no other protected areas within 1 km of the Project road 176A. 91. Therefore whereas there are some valuable ecological resources and protected sites well to the south west of the stretch of Project road TL176A selected for improvement it is not near the buffer zone or core areas protected for natural habitats for rare or endangered species.
C. Social-Cultural Environment
1. Human Issues and Quality of Life 92. Ha Giang province is situated in the northeast of Viet Nam sharing a border with China. It is enclosed by China to the north, provinces of Ha Giang to the west the province of Cau Bang and Tuyen Quang to the east and Yen Bai to the south. Total area of the province is 793,600 hectares (ha). The province has a population of 708,000 people giving a population density 89 persons/km2. Twenty-two (22) different ethnic groups including Kinh people and the rest ethnic minorities such as Mong, Tay, Dao, Nung, Giay, La Chi, Hoa, Pa Then, Co Lao, Lo Lo, Bo Y, Khmu, Tai Daeng, Yao, Tai Kao, Tai Meuay, Tai Neua, Phu Noi live in Ha Giang. More than 94% of the population lives in rural areas. Kinh people occupy 12% of the total population and live mainly in district towns and commune headquarters. 93. The average population density of 89 persons/ km2 is relatively high for a rural area especially in Asia. About 68% of the total population lives on the lowlands and the river valleys, mainly in urban areas. Yao and H’mong ethnic groups live on the lower mountainous slopes, and make up about 22% of the population. In Ha Giang, the Viet Nam Soung are highlanders who usually live in areas 1000 meters above sea level (masl) or more and they make up about 10% of the total population. They retain their traditional languages and culture in the extremely remote areas that they and inhabit. 94. The strong agricultural pressures constrain the opportunities for people living in these areas. Income levels are generally very low except in the main towns and the areas around the Project roads have some of the most disadvantaged districts in Viet Nam. A detailed description of the socioeconomic environment of the study area is given in a separate Ethnic and Poverty Assessment Report for the project.
2. Land Use 95. The Project roads run along several valleys. The dominant land use in the vicinity of the Project road stretches is mainly agriculture that has been developed over many cycles in the past centuries. There are also large areas of swidden agriculture on the hills with some areas of irrigated rice and vegetable fields in the flatter valley bottoms. There are also several towns and villages scattered all along the Project roads. The hinterland of the towns and villages is agricultural with some areas of plantation forests. 96. Ha Giang has abundant natural resources and a rugged landscape. The province is famous for limestone mountains and many caves. Du Gia Nature Reserve, with its high numbers of mammals and other wildlife species, has ecotourism potential. The FFI Society is in the process of researching ecotourism development in the area that would provide income to local communities in support of conservation.
Page 27
97. The Dong Van Karst Plateau Geopark has been declared to be of international importance and is another ecotourism attraction. The province is also home to Lung Cu peak – the northerly point of Vietnam and Cong Troi (heaven’s gate). Pho Bang and Thanh Thuy Border Crossings are important historic sites. The province has spectacular scenery. Ha Giang is famous for its intricate silk and cotton weavings and other textiles.
3. Cultural and historical sites, schools and housing 98. There are no sites of cultural significance found near Project roads. There are places of worship nearby in some villages. There are graves in a few places along the road but 5m outside the road corridor and more than 10 m from the centerline and away from where the rehabilitation and upgrading works would need to take place. 99. Schools are located along the Project roads in a few locations usually at distances of more than 30 m. The boundaries of the school playgrounds and gates are generally near the road (within 10 m) but the noise sensitive facades of the school buildings are generally set well back from the Project roads by more that 30 m; outside the corridor of impact. However three schools are particularly vulnerable to impacts as they will be closer to the works at Du Gia, Mau Due on road TL176A and Vinh Tuy, Yen Minh on road TL183. 100. Traditional shops and houses are located at intervals all along the Project roads and residential development is spread out in patches along the roads. The ROW is not marked out in detail but in the villages the front facades of some of the houses are generally next to the road (just outside the corridor of impact) with the front fences and walls or temporary structures just a few meters from the existing road edge in many places. Some land acquisition will be required in places and relocation of some properties or resettlement. Land acquisition requirements are in the Resettlement Plan.
4. Power supply 101. Electrical power is supplied in Ha Giang from the grid in Vietnam known as EVN (Electricity of Vietnam). The low voltage distribution network runs on poles adjacent to the Project road and will need to be protected during the works. Many of these poles and lines may need to be reprovisoned before the upgrading works commence to ensure continuity of power supply. Small hydropower stations are present in Ha Giang and contribute a reasonable amount of electricity for local consumption. The Project road works do not create any impacts on these stations.

V. ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES
102. This section discusses the potential environmental impacts of the proposed upgrading of road the Project roads and identifies mitigation measures to minimize the impacts in the design, construction and operation. 103. The main physical issues relate to impacts such as earthworks, erosion control, obtaining rock based construction materials, noise, dust, spoil disposal, disposal of other waste, and water quality. Blasting cannot be ruled out but the requirement for blasting is likely to be minimal and will be determined at the detailed design stage and reviewed during construction. The construction for the civil works will create dust, noise and vibration and the prevention of landslides must be addressed. The main biological issues relate to acquisition of agricultural land, impacts to rivers and removal of occasional trees in the works areas. There is no issue of interference with sites protected for their biodiversity as the stretch of Project road TL176A is about 2.5 km from the buffer zone of Du Gia Nature Reserve. There will also be no interference with protected forests as the works will be within the ROW for the Project roads. As such, adverse impacts on critical or natural habitats that which could impair the biodiversity value or function of nature reserves or protected forest areas are not foreseen. The improvements to the Project road stretches are not anticipated to lead to a reduction in the population of any recognized endangered or critically endangered species and there will be no loss of valuable habitats that could compromise the host ecosystem. Mitigation measures have been included in the EMP to prevent further conversion or degradation of biodiversity and to provide enhancement where practicable. With regard to the Dong Van Karst Plateau Geopark, the Project works are not anticipated to cause damage to this protected area since the Project will be undertaken on the existing road TL176A which will require modest widening (1 m at the most). Further, proper implementation of mitigation measures included in the EMP will avoid or minimize impacts to areas which are potentially sensitive to geological landscape and visual impacts.The social and human impacts to village life and impacts to social infrastructure will be of short duration and these have been subject to detailed assessment in the Resettlement Plan. 104. The potential environmental impacts in the design, construction and operational phases are assessed below. Where impacts are significant enough to exceed accepted environmental standards, mitigation is proposed in order to reduce residual impact to acceptable levels and achieve the expected outcomes of the project. The criteria for assessment are in line with ADBs SPS, or if the GOV standard is stricter, the national standards and criteria set by GOV. Where GOV has no set of standards or guidelines, the standards given in World Bank’s Environmental Health and Safety Guidelines5 are used. The EMP is presented in Table VIII.2 as a matrix of mitigation and monitoring measures to prevent or minimize the impacts.
A Design / Pre-Construction Phase 105. The proposed project involves upgrading of a single carriageway existing road. As the existing alignment of the road will be followed, route selection is established but there may be minor adjustment at the detailed design stage. There are a number of mitigation measures that will need to be carried out by the project detailed design consultant engineers (DDC) and checked by the PCC to avoid construction impacts by good design to minimize operational environmental impacts. DDC will be engaged by the PPMU. The PCC will be engaged by the JCC. Detailed design will be required to ensure that the upgraded road can cope with flooding. Bridges will be designed to withstand a
5 World Bank, Environmetal Health and Safety General Guidelines 2007, Washington D.C.
Page 32
100 year return storm event and culverts will be designed to withstand a 25 year return storm event in line with Viet Nam standards (TCVN 4054 – 20056). In line with ADB policy on environmentally responsible procurement, opportunities to provide environmental enhancements will also be identified in the detailed design as well as routine matters such as avoiding unnecessary removal of trees and compensatory and enhancement planting. The opportunities for design, construction and operational enhancements have been included in the Environmental Management Plan (EMP). However as the detailed designs will be completed later, the IEE (together with the EMP) will be updated by the PCC based on the designs by the DDC during the detailed design phase, or a new environmental assessment report will be undertaken for submission to ADB if there are any changes to Project design that would result to environmental impacts or risks that are not within the scope of the current IEE.
1. Design measures and project disclosure 106. The DDC in cooperation with PCC and PPMU will prepare the detailed designs to address the requirements below including, but not necessarily be limited to the following design requirements, and all relevant measures in Table VIII.2: i) Acquisition of agricultural land will be minimized for temporary facilities (if needed) by selecting preferred locations in detailed designs for construction yards and asphalt plant on barren or marginal land and agree terms with local community. ii) Potential solution spaces to ensure sufficient disposal space for cut surface spoil materials and to avoid fly-tipping will be identified in advance by the DDC and approved by PPMU and PCC and the local community before bidding. iii) Arrangements will be made to facilitate the timely production and supply of rock and bitumen based materials for construction and to avoid impacts due to unnecessary stockpiling near the Project roads. iv) Extensions and improvements of drainage culverts for the Project roads road will be designed to account for increased rain due to a once in 100 year return storm event. v) Hydrological and drainage impacts during construction will be minimized by including in the detailed design early phasing of replacement of culverts and other infrastructure. vi) Disruption to current facilities for water supply will be avoided and facilities will be retained or re-provisioned before construction works commence; provisions will be made to preserve the operation of current facilities for water supply in sufficient quantity in agreement with the local community. vii) Disruption to current power supply will be avoided and movement of power lines will be planned well in advance. Power distribution circuitry will be re-provisioned before construction works commence; provisions will be made to preserve the operation of current facilities for power supply in sufficient quantity in agreement with the local power supply company. viii) Plans to minimize disturbance of vehicular traffic and pedestrians during construction will be included in the detailed designs. Phasing for construction will retain a passing lane along part of the road during construction in detailed designs programming and avoid community severance. ix) Aim to provide enhancements under ADB policy on environmentally responsible procurement and avoid negative impacts due to unnecessary removal of trees. 107. The roads requiring improvement are part of the existing road corridor and although the RoW is wide enough for the upgrading there are some encroachments and there will

Page 33
be some requirement for resettlement. This will probably be needed at a few hundred locations subject to confirmation and these requirements are presented in the Resettlement Plan. 108. The final alignment will be disclosed to DONRE and a check will be made at the detailed design stage that the road alignment has been designed as planned. The IEE/EMP shall be updated by the PPMU/PCC and resubmitted to ADB and incorporating any recommendations and requirements from the DONRE/MONRE, should there be additional environmental impacts not identified in this IEE and for which appropriate mitigation measures have not been included in the EMP. Further, if during detailed design there are any changes to Project design (such as change in alignment) that would result to environmental impacts or risks that are not within the scope of the current IEE, the PCC during the detailed design phase shall update the IEE (together with the EMP) or prepare a new environmental assessment report for submission to ADB. Prior to preparation of the updated or new environmental assessment report, the proposed Project change shall be screened by ADB for its potential environmental impacts and risks to determine the appropriate extent and type of environmental assessment to be undertaken. During Project implementation either, an updated IEE, an updated EMP or a new environmental assessment report, as necessary, shall be submitted to ADB for clearance, if any unanticipated environmental risks and impacts arise. The appropriate document for submission shall be determined by ADB. PPMU will also establish the Grievance Redress Mechanism at this stage before site works commence.
2. Project boundaries change near sensitive receivers 109. The residential sensitive receivers (SRs) near the Project road the Project roads are generally set back sufficiently for traffic fumes to be dispersed and road traffic noise will not be sufficient to affect the sensitive receivers. At this stage and given the modest traffic flows it appears that neither the Viet Nam criterion of 60B(A) for sensitive developments such as residences or the World Bank criterion of 55B(A) at the sensitive receiver for new noise sensitive developments such as residences, schools, colleges and hospitals could comfortably be achieved in the operation al phase. Noise and dust in construction will need to be controlled. 110. There are no medical facilities near the Project roads the Project roads. The roadside cemeteries are generally set back from the working areas and the DDC will carefully design the Project road works to avoid the cemeteries. The occasional roadside tea and food stalls are also set back from the likely working areas for road rehabilitation. There are many schools in Project road areas but the sensitive facades are also set well back from the road by more than 50m. There may be some as yet unidentifiable refinements to the alignment at the detailed design stage that mean the works must take place over a slightly different area. As mentioned above, a new environmental assessment or an updated IEE (together with the EMP) shall be prepared by PPMU/PCC if refinements or changes to the project alignment, based on the detailed design, would result to environmental impacts or risks that are not within the scope of the current IEE. Such documents shall be submitted for ADB’s review before changes are implemented.
3. Environmental capacity development of PPMU 111. PCC/PPMU will make sure that PPMU’s Environmental and Safety Officer (ESO) is trained and prepared to ensure that future contractors will be primed to cooperate with the implementing agency, project management, PSC, PCC and local population in the mitigation of environmental impacts. The PPMU would dedicate a suitably qualified staff as ESO to undertake this task. The PCC will also develop strengthening plan for the environmental management by PPMU and retention of environmental staff. Details of the proposed environmental capacity building for PPMU are provided in Chapter VIII (Environmental Management Plan).
Page 34
4. Preparation of site specific EMPs 112. The contractors will be primed by including the Project EMP (Table VIII.2 of the IEE) and specific EMPs (SEMPs) in the bidding and contract documentation. Prior to bidding, the PCC will produce a series of method statements or SEMPs that the contractors will need to implement. The broad content of the SEMPs is included in the construction mitigation section. The SEMPs will demonstrate the manner (location, responsibilities, schedule/ timeframe, budget, etc.) in which the contractors will implement the mitigation measures specified in the EMP. 113. Based on the EMP, the following method statements or SEMPs shall be prepared by the PCC in the preconstruction/detailed design stage for implementation by the contractors: i) Waste Management and Spoil Disposal Plan (WMSDP) for handling, storage, treatment, transport and disposal of solid and liquid wastes, hazardous materials, hazardous wastes and excavation spoils. The plan will include a provision prohibiting disposal of wastes within the Dong Van Karst Plateau Geopark. There must also be a provision that disposal of excavation spoils within DVKPG will not be undertaken unless: a) prior approval is obtained from DVKPGMB and UNESCO, b) disposal of excavation spoils will not cause negative visual impacts, and c) will not adversely affect the protected geological resources within DVKPG. The WMSDP will also provide details of a trip ticket system to ensure that contractors dispose excavation spoils in approved areas. Such system will be designed so that the PSC and PCC could readily monitor the volume and disposal site of excavation spoils, and to ensure that the total volume of spoils disposed will not exceed the maximum capacity of disposal sites approved by local authorities. ii) Materials Management Plan (MMP) detailing arrangements to be made to facilitate the timely production and supply of construction materials to avoid impacts due to unnecessary stockpiling outside the Project site. iii) Drainage Management Plan (DMP) to ensure that construction works will not cause ponding/flooding within the Project site, construction camps, borrow/quarry areas, other areas used for project-related activities and adjacent areas. iv) Erosion Control Plan (ECP) to ensure that construction works will not cause excessive runoff and siltation of adjacent waterways within the Project site, have sufficient provisions to ensure stabilization of cut slopes and other erosion-prone areas, minimize hydrological impacts, flooding and erosion of river banks and adjacent areas and to protect the works under construction; v) Tree-cutting and Replanting Plan (TRP) to ensure indiscriminate tree-cutting shall be avoided by clearly defining areas where vegetation removal is necessary based on Project requirements and that replanting shall be done to compensate for lost trees. vi) Temporary Traffic Management Plan (TTMP) to minimize disturbance of vehicular traffic and pedestrians during construction. Access arrangements for vehicles accessing the Project area will be formulated such that this will avoid community disturbance and severance and will at least retain a passing lane along all roads used during construction. vii) Utilities and Irrigation Reprovisioning Plan (UIRP) to minimize interruption to power, water supply telecoms and irrigation system; viii) Noise and Dust Control Plan (NDCP) to minimize impacts to sensitive receptors (residential areas, schools, hospitals, etc.) due to construction works, sourcing and transport of construction materials, and other project-related activities. ix) Workers and Public Safety Plan (WPSP) to identify interfaces between the works and public and ensure worker and public safety and prevent accidents due to the construction works.
Page 35
5. Environmentally responsible procurement 114. All the above management plans will be agreed in advance with PPMU/PCC in the project preparation phase and included in contract documentation. The requirements in the contract will include full implementation of the EMP. PPMU/PCC shall ensure that the EMP are included in the bid and contract documents for civil works. PPMU shall require the contractor to engage capable and trained staff or site agents to take responsibility for the environmental management at the working level and to audit the effectiveness of the contractor’s SEMP and review mitigation measures as the project proceeds. The effective implementation of the SEMP will be audited as part of the loan conditions and the executing agency (PPC) will be prepared for this. In this regard, the JCC and PPMU (implementing agency) will also prepare to allow sufficient resources for the PCC to fulfill the EMP requirements. The international and national environment specialists in PCC will train environmental officers of PPMU to guide the contractors on the environmental aspects of road construction. This process has begun on other road projects and will be carried forward in this project. Any recent recommendations and initiatives from MONRE/DONRE or other local environmental and forestry authorities will be incorporated in the EMP and updated and audited as necessary.
6. Unexploded ordinance (UXO) 115. In order to avoid the risks from UXO and avoid accidents, the PPMU will coordinate with appropriate agencies at the design stage to identify if UXO is a potential threat to works in the project areas and PPMU shall commission UXO clearing, as necessary. The contractors shall only commence site works after advise from PPMU that the UXO clearing firm has certified that the project areas are already cleared of UXO.
7. Ambient environmental baseline data a. Air quality and Noise 116. Baseline data on air quality and noise levels shall be collected before commencement of civil works. Such data will help in assessing project impacts during implementation. 117. PCC shall collect baseline data on total suspended particulates (TSP) and noise levels at each district along the alignment. At least two weeks before commencement of civil works, field sampling for TSP and noise will be conducted at representative sensitive receptors (SR), i.e., sampling stations shall be established and sampled for various SR types as follows: (i) residential area, (ii) school/office, (iii) temple and (iv) hospital/health center. Field measurements for TSP shall be carried out using 1-hr averaging period based on the prescribed methodology in QCVN 05:2009/BTNMT (Viet Nam Ambient Air Quality Standard) 118. Noise impacts may be short lived, although can be very intrusive if not controlled properly. Noise measurement shall be undertaken at the same sites sampled for TSP and shall follow the methodology specified in TCVN 5949: 1998 (Noise in Public and Residential Areas– Allowable Noise Levels). Noise shall be measured in dB(A) over a 24 hours covering the different periods (i.e., 6h to 18h, 18h to 22h and 2h to 6h). Measurement will also be taken to establish if the World Bank criterion of Leq55dB(A)1- hour is exceeded at the measurement points. If it is exceeded by the existing noise a criterion of background +3dB(A) will be applied in the monitoring. The criterion of Leq50dB(A) can be used where background is below Leq50dB(A)1hour. Works are not expected to be carried out at night but if this is unavoidable for unexpected reasons separate measurements will also be taken before construction commences to establish if the Viet Nam criterion of Leq40dB(A)1-hour is exceeded and the monitoring assessment criteria will be established accordingly.

119. Information such as recent rainfall will be documented as part of the baseline measurement. The sampling report will also specify if the sampling was undertaken during the rainy or dry season. Time and date of sampling, sources of dust and noise emissions during the sampling period, comparison of results to applicable standards shall also be included in the report. Actual location of the sampling stations shall be described in the report and plotted on a map together with GPS readings. The noise and TSP baseline monitoring will be reported by PCC at the end of the detailed design period, either in the detailed design report or in a dedicated baseline monitoring report before the bidding documents are completed. b. Water quality 120. Baseline data on surface water quality shall be collected by PCC. Sampling points shall be established in at least three major river crossings were bridge repairs and replacement will be undertaken as well as on river/stream sections close to construction camps (i.e., rivers that will most likely receive run-off/discharge from construction/workers’ camps). Baseline sampling shall be conducted at least two weeks before civil works contractors are deployed. Parameters will include pH, temperature, turbidity, dissolved oxygen (DO), oil and grease, and total suspended solids (TSS). For rivers/streams close to construction/workers’ camps, the following additional parameters shall also be analyzed: biological oxygen demand – 5 days (BOD5), coliform and fecal coliform. Sampling and analytical methodology shall be consistent with QCVN 08:2008/BTNMT (Viet Nam National Regulation for Surface Water Quality). 121. PCC shall collect water samples 20 m before (upstream) and 20 m after (downstream) the bridges at mid-width and mid-depth at each of the river crossings along the road alignment to establish a reference baseline. An industry standard multi- parameter water quality meter could be used for pH, DO, turbidity and temperature. 122. Information on weather conditions during sampling, recent rainfall, etc. will be documented as part of the baseline measurement. The sampling report will also specify if the sampling was undertaken during the rainy or dry season. Time and date of sampling, potential sources of contaminants/pollutants during the sampling period, comparison of results to applicable standards shall also be included in the report. Actual location of the sampling stations shall be described in the report and plotted on a map together with GPS readings. The water quality baseline monitoring will be reported by PCC at the end of the detailed design period, either in the detailed design report or in a dedicated baseline monitoring report before the bidding documents are completed.

123. For rivers that do not mix well, and/or are highly polluted such that it is likely that there will be different DO and TSS values at river bottom than at mid depth, samples shall be collected near river bottom. 124. Information such as recent rainfall will be documented as part of the baseline measurement. The sampling report will also specify if the sampling was undertaken during the rainy or dry season. Potential sources of pollution shall also be included in the report. 125. The (Table V.2) below shows the QCVN standards that will be used for the Project.

8. Enhancements 126. Environmental enhancements have not been a major consideration in the assessment of earlier projects. However it is noted that it has been common practice in many paces to plant trees along highways to provide visual interest in line with best international practice for highway design. Locations to create some local soft landscaping where successful planting of trees and shrubs could be accomplished and should be investigated at the detailed design stage. This practice should be in addition to tree replacement and be encouraged as far as practicable and to foster good will with the local community. It is also possible that the cross drainage and culverts may be modified to assist in the collection of surface water for irrigation purposes. Other opportunities for enhancements can be assessed prior to construction and proposed enhancements should be discussed with the local population to identify stewardship of any planting and also to serve as a vehicle for further public consultation at the implementation stage and to assist in public relations.
9. Measures to ensure protection of Don Van Karst Plateau Geopark (DVKPG) 127. The chairman of Dong Van Karst Plateau Geopark Management Board indicated that they did not have any in principle objection to the Project road and the widening of the road was not a concern to DVKPGMB because the roads works were modest and the road has been in place for many years before the DVKPG was declared. 128. However the DVKPG is potentially sensitive to environmental change as a result of the Project road stretch TL176A. DVKPG is recognized by UNESCO and the DVKPGMB must be notified about the project in advance in due course. DVKPGMB do not envisage any difficulties in obtaining UNECO concurrence for the Project road but it will be necessary to compile a report for UNESCO in advance. Hence DVKPGMB must be informed and consulted as soon as possible in the detailed design phase so that the requisite report can be compiled for UNESCO. Therefore the following mitigation measures are included in the EMP. i. Contact and liaise with Dong Van Karst Plateau Geopark Management Board and all relevant local authorities, district and commune PPCs.
Page 38
ii. Work with DVKPGMB and relevant local authorities, to provide sufficient information for DVKPGMB to prepare the necessary reports to DVKPGMB’s national and international collaborators and supporting organizations. iii. Ensure that there is sufficient time to compile report and inform collaborators (e.g. UNESCO) prior to bidding. iv. Commence bidding only after receipt of concurrence from collaborators including UNESCO. v. Any additional requirements or mitigation measures shall be implemented and operational before start of construction of on the relevant Project road 176A.
B Construction Phase 129. The source of the construction impacts from Project roads will include (i) excavation and reconstruction of the embankments, (ii) reconstruction of the single carriageway pavement (5.5 m wide) plus hard shoulders; (iii) construction, repair and reconstruction of bridges (iv) ensuring road drainage and access near villages and at other key areas is unimpaired by extension of numerous culverts; and (vi) installing slope stabilization and bioengineering measures, landscaping and accessories. In the hilly areas there will also be some slope cutting which will give rise to significant amounts of spoil for disposal. In this IEE project construction supervision is assumed to be carried out by PPMU.
1. Activate SEMPs and obtain permits and licenses. 130. The PCC will be engaged by JCC to assist PPMU in line with ADB policy on environmentally responsible procurement. The PCC will train and supervise the contractors to carry forward the environmental mitigation measures and enhancements identified in the detailed designs. The PCC will prepare SEMPs at the design stage. The benchmark for monitoring and reporting on the contractor’s environmental performance are the Project EMP (Table VIII.2 of the IEE), SEMPs,and any additional mitigation measures that may be required during construction phase. PPMU shall ensure that contractors and their suppliers comply with all statutory requirements for permits from DONRE with regard to use of mechanical equipment, establishment and operation of construction plants such as asphalt plant, concrete batching plant, rock crusher, spoils disposal, etc.
2. Orientation of contractor 131. PCC shall orient the workers on implementation of construction mitigation measures in the Project EMP, SEMPs and any additional mitigation measures that may be required during construction phase.
3. Loss of trees and impacts to fauna 132. The tree-cutting and replanting plan (TRP) designed by the PCC will be prepared with the designs and before vegetation clearing is undertaken. Cut slopes will be designed not to undercut or destabilize adjacent tree lined slopes and clearing of trees will be minimized in SEMP. The local forestry authority will be informed and will approve cutting and replacement of cut of trees based on the TRP. The PCC and PSC will ensure that contractors follow the TRP and local forest authorities may monitor marking of vegetation that will be removed under its jurisdiction. The TRP will be agreed with forest authority prior to commencement of construction. The PSC and PCC will supervise and monitor to check that the contractors do not remove any trees not covered by the TRP prior to commencement or during construction unless agreed with the PSC, PCC, PPMU and forest authority. 133. The PSC and PCC will supervise and monitor to check that the contractors to carry forward the mitigation measures and environmental enhancements identified in the
Page 39
SEMP as well as routine matters such as avoiding unnecessary removing of trees and compensatory and enhancement planting. 134. The PSc and PCC will supervise and monitor a ban on use of forest timber and Workers shall be prohibited from cutting trees for firewood. 135. Invasive species shall not be introduced. During replanting/revegetation works, new alien plant species (i.e., species not currently established in the region of the project) shall not be used unless carried out with the existing regulatory framework for such introduction. All replanting and compensatory planting will be planned in full agreement with the local forest authority. 136. The contractors will not use or permit the use of wood as a fuel for the execution of any part of the Works, including but not limited to the heating of bitumen and bitumen mixtures, and to the extent practicable shall ensure that fuels other than wood are used for cooking, and water heating in all his camps and living accommodations. The contractors shall not buy or use wood from the illegal sources (that come from the illegal logging). No construction camps, asphalt mixing plants, material storage sites are to be located in the forest areas. The contractors will take all precautions necessary to ensure that damage to vegetation is avoided due to fires resulting from execution of the works. The Contractor will immediately suppress the fire, if it occurs, and shall undertake replanting to replace damaged vegetation. 137. The PPMU, PSC and PCC will supervise and monitor a ban on use of forest timber that will be included in the SEMP and workers shall be prohibited from cutting trees for firewood. The TRP will include as a minimum consideration of: i) Identification of trees to be cut and locations ii) Ban on use of timber for fuel and ban taking of cycads and orchids from forests. iii) Justification for tree cutting as and alternative to road realignment. iv) Permissions from land owners, authorities and permits from PFPD for cutting. v) Methods for marking, protection of uncut cut trees and limitations to cutting. vi) Methods and timing for safe cutting to minimize interference with normal traffic. vii) Methods to remove trees cut timber and avoid stockpiling cut brushwood on site. viii) Methods to avoid under cutting adjacent tree lined slopes. ix) Programme for cutting trees and enhancement planting. x) Compensatory tree planting programme agreed with authorities & PFPD. xi) Discussion of the PSC, PCC/PPMU inspection/monitoring role. xii) Agreement on publicity/public consultation requirements.
4. Drainage and hydrology 138. The drainage system, irrigation and water resources on surrounding lands will be affected by construction activities as follows: a) local water supplies will need to be tapped to meet campsite and construction requirements, so bringing project based water use into competition with local use; b) surface and subsurface water resources near the selected Project road sections could be contaminated by fuel and chemical spills, or by solid waste and effluents generated by the kitchens and toilets at construction campsites; c) irrigation channels cross the works areas and require reprovisioning, (d) natural streams may become silted by borrow material (earth) in the runoff from the construction area, workshops and equipment washing-yards. The contractors will be required to implement the provisions of the Drainage Management Plan and to provide drainage facilities to avoid ponding/flooding within the Project site, construction camps, borrow/quarry areas, other areas used for project-related activities and adjacent areas. Potential impacts on water quality are already identified in the subsequent sections (e.g., under hazardous materials and hazardous waste disposal, water quality, etc.). 139. In areas close to the sensitive receiver (SR), the contractors will provide appropriate drains so that the outfalls of the surface run-off from the carriageway are diverted away
Page 40
from the SR. Measures will also be taken by the contractors during the construction phase to ensure that storm drains and road drainage systems are regularly cleared to maintain storm water flow.
5. Utilities and reprovisioning 140. Local water supplies, electrical power supply, telecommunications and irrigation water supply must be maintained during the works. Therefore the need to reprovide for power supply cables, telecommunication cables, irrigation or other water supplies needs to be reassessed and reconfirmed by the contractors well before works commence. Therefore the contractors will: i) Discuss with PCC and PPMU and update Utilities and Irrigation Facilities Reprovisioning Plan ii) Reconfirm railway, power, water supply, telecommunications and irrigation systems likely to be interrupted by the works and trees to be cut. iii) Contact all relevant local authorities for utilities and local village groups to plan reprovisoning of power, water supply, telecommunications and irrigation systems. iv) Relocate and reconnect utilities well ahead of commencement of construction works and coordinate with the relevant utility company at the provincial and district levels for relocation and reconnection well before works commence and include for compensatory planting for trees. v) Inform affected communities well in advance. vi) Arrange reconnection of utilities and irrigation channels in the shortest practicable time before construction commences. vii) If utilities are accidentally damaged during construction it shall be reported to the PSC, PCC and utility authority and repairs arranged immediately at the contractor’s expense.
6. Materials exploitation and management of quarry and borrow areas 141. In the detailed design stage the PCC will produce a Materials Management Plan (MMP) for implementation by the contractors. The plan must have a provision that no quarry sites and borrow areas within the Dong Van Karst Plateau Geopark shall be established and/or used for the Project unless: a) prior approval is obtained from DVKPGMB and UNESCO, and b) such activities will not cause negative impacts on the protected geological resources and landscape within DVKPG.The MMP will seek, as far as is reasonably practicable, to minimize the use of non-renewable resources and rock based materials and also to balance cut and fill requirements and contribute to the minimization of impacts due to extraction of rock based materials. As a first priority, where surplus materials arise from the removal of the existing surfaces these will be used elsewhere on the project for fill (if suitable) before additional rock, gravel or sand extraction is considered. The TA team has estimated that less than 10% may be reusable. 142. The MMP will include as a minimum consideration of the following: i) Required materials, potential sources and estimated quantities available. ii) Impacts to identified sources and availability. iii) Excavated slope material for reuse and recycling methods to be employed. iv) Endorsement from DONRE and local groups for use of sources. v) Methods of transportation to minimize interference with normal traffic. vi) Constraints of regular delivery schedule to reduce stockpiling on site. vii) Programme for reuse of slope excavated material for reuse viii) Programme for delivery of quarry and borrow materials. ix) Discussion of the PSC, PCC/PMU inspection/monitoring role. x) Agreement on publicity/public consultation requirements. 143. The contractors will be responsible to:
Page 41
i) Balance cut and fill requirements to minimize impacts from extraction of aggregates. ii) Ensure that no quarry sites and borrow areas within the Dong Van Karst Plateau Geopark are established and/or used for the Project unless: a) prior approval is obtained from DVKPGMB and UNESCO, and b) such activitites will not cause negative impacts on the protected geological resources and landscape within DVKPG. iii) Prioritize use of existing quarry sites with suitable materials and update the list of quarries and borrow pits monthly in MMP and report to PPMU and minimize impacts on other local resources. iv) Procure materials only from DONRE authorized quarries and borrow sites. v) If the contractors shall operate the quarry site, required environmental permits shall be secured prior to operation of quarry/borrow areas. vi) Borrow/quarry sites shall not be located in productive land and forested areas. vii) Follow compensatory planting plan if trees have to be removed. viii) Stockpile topsoil for later use and fence and re-contour borrow pits after use ix) Topsoil, overburden, and low-quality materials shall be properly removed, stockpiled near the site, and preserved for rehabilitation. x) Use quarry with highest ratio between extractive capacity (both in terms of quality) and loss of natural state. xi) Use quarry sites lying close to the alignment, with a high level of accessibility and with a low hill gradient; xii) Do not use quarries in areas of natural woodland or near rivers which provide food and shelters for birds and other animals. xiii) Damaged access roads agricultural land and other properties due to transport of quarry/borrow materials, other construction materials and due to various project-related activities shall be reinstated upon completion of construction works at each section. xiv) During quarry/borrow site operation, provide adequate drainage to avoid accumulation of stagnant water. xv) It is preferable to avoid or reduce the sections of quarry sites located on river bed. If it is not possible to locate quarries out of river beds, quarry sites lying on small rivers and streams shall be avoided. xvi) Alluvial terraces or alluvial deposits which lie on the river beds but not covered by water in normal hydrological conditions, shall be preferred; xvii) In quarries in the mountainous or hilly areas, or wherever slopes are important, cut terraces after extraction and implement a drainage system and vegetation cover for rehabilitation. xviii) Upon completion of extraction activities, quarry and borrow pits shall be dewatered and fences shall be installed, as appropriate, to minimize health and safety risks. xix) Ensure borrow pits are left in a tidy state with stable side slopes and proper drainage in order to avoid creation of water bodies favorable for mosquito breeding xx) To avoid drowning when pits become water-filled, measures such as fencing, providing flotation devices such as a buoy tied to a rope, etc. shall be implemented.
7. Spoil Disposal 144. The works will require major cutting to upgrade Project roads. It is estimated by the TA team that about 353,258 m3 of soil and rock based materials must be cut. The
Page 42
requirement for filling materials is expected to be much less (about 161,289 m3) and the TA team estimated that less than 10% can be reused near the same area for filling. Therefore there will be a surplus of more that 300,000m3 of soil based materials for reuse as fill material or disposal as spoil elsewhere. Therefore there will be a significant surplus of rock and soil based materials as spoil and if disposal is not planned in advance there will be significant impacts and environmental degradation due to the improper disposal of these materials. 145. In some locations the use of this immediately available material will reduce the need for additional extraction of rock based materials. The surplus material should be graded and the suitable cut materials directed for reuse as far as possible on Project roads and subsequently on other roads and other local infrastructure projects. This will reduce the need to extract other rock and gravel resources from vulnerable hillsides and river beds. The surplus can then be stockpiled at locations agreed with local authorities for use on other local district projects or other nationally planned infrastructure. 146. The surplus rock and soil based materials for disposal must be controlled to avoid potential impacts due improper disposal. A waste management and spoil disposal plan (WMSDP) will be required to ensure waste from Project road upgrading is managed properly and to reduce, reuse and recycle waste wherever possible. Contractors will initially review the PCC’s options for stockpiling and disposal locations for cut surface materials and reconfirm or propose alternative disposal locations for agreement with PPMU and local authorities. The WMSDP will cover all aspects of construction waste disposal. It is preferred that government land is used for dumping of material. If private land is to be used for the purpose of dumping it shall commence only after written permission from the land owner is checked and recorded by the PPMU and PCC and agreeable to DONRE. 147. Mitigation measures will seek to control the impacts at source in the first place. The PPMU assisted by the PCC will be responsible to report the update of the cut and fill estimates in conjunction with asphalt and aggregate materials planning (MMP) between the different areas and advise on overall balancing for cut and fill materials to minimize impacts on local resources. (Mitigation measures for cut slopes are covered under erosion control). 148. The Spoil Disposal section of the WMSDP will include consideration of the following i) Disposal of excavation spoils within DVKPG will not be undertaken unless: a) prior approval is obtained from DVKPGMB and UNESCO, b) disposal of excavation spoils will not cause negative visual impacts, and c) will not adversely affect the protected geological resources within DVKPG. ii) Locations and quantities of spoil arising. iii) Agreed locations for disposal / endorsement from DONRE and local groups. iv) Methods of transportation to minimize interference with normal traffic. v) Establishment of acceptable working hours and constraints. vi) Agreement on time scale and programme for disposal and chain of custody. vii) Programming issues including the time of year and available resources. viii) Details of a trip ticket system to ensure that contractors dispose excavation spoils in approved areas. Such system will be designed so that the PSC and PCC could readily monitor the volume and disposal site of excavation spoils, and to ensure that the total volume of spoils disposed will not exceed the maximum capacity of disposal sites approved by local authorities. ix) Discussion of the PSC, PCC/PMU inspection/monitoring role. x) Establishment of complaints management system for duration of the works xi) Agreement on publicity/public consultation requirements (advance signing etc.). 149. Mitigation measures will seek to prevent slope collapse impacts and control the impacts at source in the first place. The PPMU assisted by the PSC and PCC will be responsible to monitor the progress of cutting slopes and the implementation of
Page 43
mitigation measures, to minimize impacts. The mitigation measures in the Spoil Disposal section of the WMSDP will include but not necessarily be limited to: (i) Disposal of excavation spoils within DVKPG will not be undertaken unless: a) prior approval is obtained from DVKPGMB and UNESCO, b) disposal of excavation spoils will not cause negative visual impacts, and c) will not adversely affect the protected geological resources within DVKPG. (ii) Spoil will not be disposed of in rivers and streams or other natural drainage path. (iii) Spoil will not be disposed of on fragile slopes, flood ways, wetland, farmland, forest, religious or other culturally sensitive areas or areas where a livelihood is derived. (iv) Surplus spoil will be used where practicable for local repair works to fill eroded gullies and depression areas and degraded land in consultation with local community. (v) Spoils shall only be disposed to areas approved by local authority. (vi) Spoil disposal will be monitored by PSC, PCC/PPMU and recorded using a written chain of custody (trip-ticket) system to the designated disposal sites. (vii) Spoil will be to disposed of to disused quarries and abandoned borrow pits where practicable. (viii) Disposed spoil will be spread in 15 cm layers and compacted to optimum moisture content, covered with topsoil, landscaped and provided with drainage and vegetation to prevent erosion in line with best practice. (ix) Spoil disposal shall not cause sedimentation and obstruction of flow of watercourses, damage to agricultural land and densely vegetated areas. (x) Under no circumstances will spoils be dumped into watercourses (rivers, streams, drainage, irrigation canals, etc.) (xi) The spoils disposal site shall be located at least 50 m from surface water courses and shall be protected from erosion by avoiding formation of steep slopes and grassing.
8. General Construction Waste Management 150. Uncontrolled waste disposal operations can cause significant impacts. Mitigation measures will seek to reduce, recycle and reuse waste as far as practicable. The PPMU assisted by the PCC will be responsible to monitor the contractor’s progress of implementing the provision of the WMSDP and mitigation measures specified in the Project EMP. 151. The General Waste section of the WMSDP will include consideration of all matters related to solid and liquid waste disposal including the following: i) Wastes will not be disposed within DVKPG. ii) Expected types of waste and quantities of waste arising. iii) Waste reduction, reuse and recycling methods to be employed iv) Agreed reuse and recycling options and locations for disposal / endorsement from DONRE and local groups. v) Methods for treatment and disposal of all solid and liquid wastes. vi) Methods of transportation to minimize interference with normal traffic. vii) Establishment of regular disposal schedule and constraints for hazardous waste. viii) Programme for disposal of general waste / chain of custody for hazardous waste. ix) Discussion of the PSC, PCC/PMU inspection/monitoring role. x) Establishment of complaints management system for duration of the works xi) Agreement on publicity/public consultation requirements (advance signing etc.). 152. The Contractors mitigation measures in the General Waste section of the Spoils WMSDP will include but not necessarily be limited to the measures listed below. The contractors shall ensure implementation of these measures.
Page 44
i) Disposal of wastes will not be undertaken within the Dong Van Karst Plateau Geopark . ii) Areas for disposal to be agreed with local authorities and checked and recorded and monitored by the PSC, PCC/PPMU. iii) Segregation of wastes shall be observed. Cleared foliage, shrubs and grasses may be given to local farmers for fodder and fuel. Organic (biodegradables) shall be collected and disposed of on site by composting (no burning on site). iv) Recyclables shall be recovered and sold to recyclers. v) Residual and hazardous wastes shall be disposed of in disposal sites approved by local authorities. vi) Construction/workers’ camps shall be provided with garbage bins. vii) Burning of construction and domestic wastes shall be prohibited. viii) Disposal of solid wastes into canals, rivers, other watercourses, agricultural field and public areas shall be prohibited. ix) There will be no site-specific landfills established by the contractors. All solid waste will be collected and removed from the work camps and disposed in local waste disposal sites. x) Waste disposal areas approved by local authorities shall be rehabilitated, monitored, catalogued, and marked.
9. Hazardous materials and hazardous waste disposal 153. Use of hazardous substances such as oils and lubricants can cause significant impacts if uncontrolled or if waste is not disposed correctly. Mitigation measures will seek to control access to and the use of hazardous substances such as oils and lubricants and control waste disposal. The PPMU assisted by the PSC and PCC will be responsible to monitor the contractor’s progress of implementing the WMSDP to avoid or minimize impacts from use of hazardous substances such as oils and lubricants. 154. The Contractors mitigation measures in the Hazardous Waste section of the Spoil and Waste Management Plan of the SEMP will include but not necessarily be limited to the following measures. The contractors shall ensure implementation of such measures. i) Ensure that safe storage of fuel, other hazardous substances and bulk materials are agreed by PPMU/PCC and PSC and have necessary approval/permit from DONRE and local authorities. ii) Hydrocarbon, toxic material and explosives will be stored in adequately protected sites consistent with national and local regulations to prevent soil and water contamination. iii) Equipment/vehicle maintenance and refueling areas will be confined to areas in construction sites designed to contain spilled lubricants and fuels. Such areas shall be provided with drainage leading to an oil-water separator that will be regularly skimmed of oil and maintained to ensure efficiency. iv) Fuel and other hazardous substances shall be stored in areas provided with roof, impervious flooring and bund/containment wall to protect these from the elements and to readily contain spilled fuel/lubricant. v) Segregate hazardous wastes (oily wastes, used batteries, fuel drums) and ensure that storage, transport and disposal shall not cause pollution and shall be undertaken consistent with national and local regulations. vi) Ensure all storage containers are in good condition with proper labeling. vii) Regularly check containers for leakage and undertake necessary repair or replacement. viii) Store hazardous materials above flood level. ix) Discharge of oil contaminated water shall be prohibited. x) Used oil and other toxic and hazardous materials shall be disposed of in an authorized facility off-site.
Page 45
xi) Adequate precautions will be taken to prevent oil/lubricant/ hydrocarbon contamination of channel beds. xii) Ensure availability of spill clean up materials (e.g., absorbent pads, etc.) specifically designed for petroleum products and other hazardous substances where such materials are being stored. xiii) Spillage, if any, will be immediately cleared with utmost caution to leave no traces. xiv) Spillage waste will be disposed at disposal sites approved by local authorities and approved by PSC/PPMU. xv) All areas intended for storage of hazardous materials will be quarantined and provided with adequate facilities to combat emergency situations complying with all the applicable statutory stipulation. xvi) The contractors shall identify named personnel in the management plan/SEMP in-charge of storage sites for hazardous materials and ensure they are properly trained to control access to these areas and entry will be allowed only under authorization.
10. Asphalt, hot mix plant, rock crushing and bitumen supply 155. The rock crushing activities will generate noise and dust and pavement works will generate gas and odor from the asphalt hot-mix plant and noise from the compaction of the pavement. Upgrading Project roads will require more than 160,000 m3 of rock based material and about more than 2,000 tons of asphalt. Although the emissions from powered mechanical equipment that supply crushed rock and bitumen will be rapidly dispersed in the open terrain they will need to be sited carefully to avoid complaints. The works for the pavement in any section of the road are estimated by the TA Team to take only 1 to 2 weeks depending on the terrain and therefore emissions from mobile powered mechanical equipment for road surfacing will be short lived. 156. In order to maintain the existing air quality of the project area in a condition acceptable to the local population compliance with the following mitigation measures will be needed: (i) Cement batching and aggregate mixing plant shall be located as far as possible (preferably at least 500m) from settlements and habitation or as required by environmental regulations. (ii) All conditions of DONRE permits and local guidelines shall be observed. (iii) Dust suppression equipment shall be installed at cement and aggregate mix plants. (iv) Areas of construction on the roads as well as the haul road (especially where the works are within 50m of the SRs) shall be maintained damp by watering the construction area. (v) Where local roads are used for haulage they shall be kept in serviceable condition and any damage shall be repaired promptly without interference to local travel routes. (vi) Storage sites, mixing plants, and bitumen (hot mix) plants will be at least 500m downwind of the nearest human settlements or as otherwise required under DONRE permits and guidelines. (vii) All hot-mix plants, crushers, and batching plants will be located in agreement with the local town or municipality and installed on a sealed area only after receiving approval from the relevant local authority and DONRE. (viii) The above Project facilities (asphalt plant, crushing plant, etc.) will not be located within Dong Van Karst Plateau Geopark. 157. Due to the locations of the works fumes from bitumen and chemicals are likely to be well dissipated in the open terrain and the TCVN/QCVN standards should not be exceeded. However phenol compounds in the bitumen have a very low odor threshold and extremely low concentrations can cause nuisances. These are unlikely to
Page 46
accumulate to toxic levels but the plant for the supply of molten bitumen should be sighted as far away from sensitive receivers as is practicable. Asphalt plant and rock crusher activities (if required) will be controlled and hot-mix plants should not be located within 500m of any sensitive receiver, river bank or irrigation channel but located at convenient sites nearby but at least 500m (in the prevailing downwind direction) from sensitive receptors such as residences, schools, hospitals. 158. Bituminous materials will generally be applied using machines but if bituminous compounds are to be applied by hand labor methods and melted in heaters the fuel used shall be kerosene, diesel or gas fuel. Fuel wood shall not be used for heating bitumen; neither will bitumen be used as fuel. 159. Bitumen drums will be stored in a dedicated area, not scattered along the works and any small accidental spills of bitumen or chemicals will be cleaned up immediately. The waste including the top 2cm of any contaminated soil and disposed of as chemical waste to an approved landfill or approved local authority disposal site in line with the WMSDP. 160. It is possible that contamination of soil may occur from oils and chemicals at bitumen plant sites, workshop areas, equipment washing-yards and along the roads works. The contamination may limit the future use of land for agricultural purposes. 161. The following practices will be adopted to minimize the risk of soil contamination: i) The contractors will prevent soil contamination and will be required to instruct and train their workforce in the storage and handling of materials and chemicals that can potentially cause soil contamination. ii) Debris generated by the dismantling of existing pavement will be recycled subject to the suitability of the material. iii) Bitumen will not be allowed to enter either running or dry streambeds and nor will be disposed of in ditches or small unlined waste disposal sites prepared by the contractor. iv) Bitumen storage and mixing areas shall be protected against spills and all accidentally contaminated soil must be properly handled according to applicable national and local laws and regulations. As a minimum, these areas must be segregated, such that any spills can be immediately contained and cleaned up. v) Any petroleum products used in the preparation of the bitumen mixture must also be carefully managed to avoid spills and contamination of the local water table and streams. Bitumen and other hydrocarbon residues will be disposed of as hazardous waste. vi) All accidental spills of bitumen or chemicals will be cleaned up immediately with the top 2cm of any contaminated soil underneath and disposed of as chemical waste to a site approved by the local authority. vii) Solid waste generated during construction and at campsites will be properly treated and safely disposed of only in demarcated off-site waste disposal sites identified and agreed with PPMU and the local community and local authorities.
11. Noise and Dust 162. Earthworks and rock crushing activities will be the main sources of dust. The works in any given section of the road will generally be of short duration and in many locations there will be sufficient buffer distance between the work corridor and the existing SRs such that no significant impact is expected from the construction works on residential sensitive receivers in terms of noise, vibration, and dust. Also works will not take place at night except in special circumstances justifiable to the PSC and PPMU.
Page 47
163. However noise and dust were recognized as nuisances by the local population but were also considered acceptable nuisances in view of the likely short duration of the works and that there were good benefits from future improved road conditions. Nevertheless it is good practice to control all dusty materials at source so that nuisances do not occur and visibility on the adjacent road is not impaired and so that road safety can be maintained or improved. As a general approach it is recommended that if works are within 15m of any sensitive receivers, the contractor should install dust barrier segregation between the works at the road edge and the sensitive receivers. The segregation should be easily erectable 2.5m high and designed to retain dust and provide a temporary visual barrier to the works. The materials could be plastic or tarpaulin sheets or alternatively sections of the locally made close woven fences could be used (made by local artisans). Where dust is the major consideration the barrier can take the form of tarpaulins or fences strung between two poles mounted on a concrete base. These can be moved along the road as the work proceeds. The other mitigation measure will include: i) If the surface is dry water will be sprinkled on the road and exposed surfaces when work is carried out within 50m of residences or roadside food stalls. ii) No work will be carried out within 500m of any settlement during the night (2100hrs to 0700hrs). iii) If works have given rise to complaints over dust, the contractor shall investigate the cause, report it in the monthly progress reports and review and propose alternative mitigation measures before works recommence. iv) All heavy equipment and machinery shall be fited in full compliance with the national and local regulations (TCVN 5949 – 1998). v) Fuel-efficient and well-maintained haulage trucks will be employed to minimize exhaust emissions. Smoke belching vehicles and equipment shall not be allowed and shall be removed from the project. vi) Vehicles transporting soil, sand and other construction materials will be covered with tarpaulin sheets to avoid impact from dust. Speed limits of such vehicles within the works site and on unpaved edge areas of the Project roads will be established and agreed with the PSC. 164. The need for large stockpiles should be minimized by careful planning of the supply of materials from controlled sources. Stockpiles should not be located within 100m of schools, hospitals or other public amenities such as wells and pumps and should be covered with tarpaulins when not in use and at the end of the working day to enclose dust. If large stockpiles (more than 25 m3) of crushed materials are necessary they should be enclosed with side barriers and also covered when not in use. 165. Schools are particularly vulnerable to construction impacts and the scheduling of works near schools should be scheduled after discussions with the school principals to avoid impacts. In addition, as a general approach it is recommended that if works are within 15 m of schools school façade the contractor should install dust barrier segregation between the works and the school façade. The segregation should be easily erectable 2.5 m high and designed to retain dust and provide a temporary visual barrier to the works. In addition, it is recommended that where the schools request, close-fitting dust barrier segregation shall be provided to cover school windows and doors during the works. 166. PCC shall undertake semi-annual monitoring of TSP and noise at the stations which were sampled during pre-construction phase. Field measurements shall also be carried out, as necessary, to validate complaints.
Page 48
12. Blasting and vibration 167. At this stage the specific requirement for blasting is not known. It is clear from discussions with the project team and observations that blasting will not be the method of choice because most of the surface materials can be removed with powered mechanical equipment (PME). It is therefore anticipated that powered mechanical equipment and a lot of local labor with hand tool methods will be used to upgrade the Project roads. 168. In the event that blasting is required in special circumstances only controlled blasting will be allowed. Blasting will only be carried out in line with the rules set down by the local authorities and DONRE in the prescribed manner and after prior notice to all local residents and the local town authorities. One month prior to the blasting in any area, the contractors will undertake a condition survey including photographs will be made of all residences within 500 m of the blast sites. The condition of the residences shall be agreed with the PSC in case there are any future claims for damage to residences due to the blasting. All blasting shall be carried out in the daytime and at regular intervals after siren warnings. All residents within 500m of the blast sites shall be kept informed of the plans and progress of blasting and residents shall be temporarily evacuated and provided with alternative accommodation if required. 169. No blasting will be allowed at night. Controlled blasting will strictly follow the license requirements from DONRE and other authorities. Pre-splitting should be undertaken. Where the vibration from blasting is exceeding the maximum permissible level, information from the blasting should be used to modify blasting patterns and calculate a reduced charge for future blasts with the aim of eradicating damage and to minimize damage as far as possible. Blasting shall be under careful and strict management of properly trained and licensed personnel. The contractor shall observe proper warning and precautionary measures to ensure safety of residents, pedestrians, motorists and structures during blasting.
13. Erosion control and runoff 170. Engineering controls that include erosion protection measures will be designed and installed to control soil erosion both at all the constructed works and in peripheral areas, particularly in borrow areas and along haul tracks. The Erosion Control Plan (ECP) produced by the PCC and slope stabilization measures in the detailed designs will be implemented and maintained by the contractors during construction to protect the works. 171. The ECP will include consideration of the following: i) Climate and rainfall for the area and checking weather forecasts. ii) Terrain and typical locations susceptible to erosion and runoff. iii) Protection of the works and potential impacts to the environment. iv) Erosion control methods to be employed, locations and installation timing. v) Limits to stockpiling on sites near waterways and irrigation channels. vi) Discussion of the PSC, PCC/PPMU inspection/monitoring role. vii) Agreement on publicity/public consultation requirements. 172. Mitigation measures for cut slopes will be required by the contractors to prevent slope collapse. These will include but not necessarily be limited to: (i) Stockpile topsoil for immediate replanting after completion of work. (ii) Minimize damage and cutting of surrounding vegetation during slope formation. (iii) Protect the cut slope with planted vegetation, bioengineering or conventional civil engineering structures as soon as practicable after cutting. (iv) Prevent erosion and protect the cut slope with temporary or permanent drainage as soon as practicable after cutting.
Page 49
(v) If new erosion occurs accidentally, back fill immediately to restore original contours. 173. In order to preserve the constructed slopes and other works and embankments from soil erosion and runoff. i) Low embankments will be protected from erosion by seeding and planting indigenous grasses that can flourish under local conditions. ii) High embankments, i.e. 2m high and above, will be considered for protection by constructing stone pitching or a riprap across the embankment immediately after the works are completed. This practice will also be applied along cross-drainage structures where embankments are more susceptible to erosion by water runoff. iii) The contractors will also be required to include appropriate measures for slope protection, i.e. vegetation cover and stone pitching, as required in the detailed construction drawings and implement them accordingly. 174. Payments will be linked to the completion of the works as indicated by the installation of erosion control measures to protect the works to the satisfaction of PCC/PMU.
14. River protection and bridge repair 175. The Project proposes to replace or repair 204 culverts and 2 bridges. Careless construction and poor materials control can cause blockage to rivers and streams. Therefore in areas along and near rivers and streams the following will be carried out: i) Earth and stones will be properly disposed of so that they do not block rivers and streams, resulting in adverse impact on water quality and flow regime. ii) In bridge repair and demolition sites, the bridge structure will not be dropped into the river but alternative means will be used to avoid "dropping the bridge" into rivers/streams. This will be done by "sawing" appropriate sections of the bridge and using cranes to lift these sections away or alternatively by construction of a platform onto which the bridge could be lowered. iii) Cofferdams, silt fences, sediment barriers or other devices will be used as appropriate based on the design to prevent migration of silt during excavation and boring operations within streams. If cofferdams are used, these will be dewatered and cleaned to prevent siltation by pumping from cofferdams to a settling basin or a containment unit. iv) Other erosion control measures above and covering open surfaces with grasses and creepers to reduce runoff will be implemented as early as possible in construction.
15. Water Quality 176. In order to prevent water contamination the following precautionary measures will be undertaken by the contractors: i) Lubricants will be stored in dedicated enclosures with a sealed floor >50m from water bodies. ii) Solid waste from construction activities will not be thrown in rivers and shall be disposed of as per the WMP and there will be NO BURNING of waste. iii) Construction storage/stockpiles shall be provided with bunds to prevent silted run-off. iv) Stockpiled materials will be covered to reduce run-off. v) Stockpiling or borrow sites will not be allowed within 100m of water body. vi) If complaints occur there will be monitor and investigation of water quality. vii) Work in rivers will be scheduled during dry season and work duration shall be as short as possible.
Page 50
viii) Bare slopes shall be stabilized Immediately after works completed. ix) Stockpile areas and storage areas for hazardous substances shall be located away from water bodies. x) Washing of machinery and vehicles in surface waters shall be prohibited. 177. If complaints are received, the incidents and possible sources of water supply disruption will be investigated by the ESO in PPMU (assisted by the PCC) and where the complaint can be substantiated; water samples will be taken and analyzed based on the baseline monitoring results. In response to complaints to either the contractor or the local authorities the PCC and the PPMU will be immediately informed so that water quality measurements will be taken (by ESO assisted by PCC) 20 m before (upstream) and 20 m after (downstream) of the works giving rise to complaint in line with the methodology used in for baseline sampling. Samples will be taken as soon after the complaint as possible and analyzed immediately and again two weeks after the complaint to determine if water quality has been restored. Impacts will be determined by reference to the baseline results from the preconstruction stage. The criteria will be based on the QCVN 08 2008 BTNMT.
16. Water Resources 178. The availability of water for the works will need to be investigated by the PCC at the detailed design stage. A preliminary assessment of water availability should include consultation with the local authorities. In the event that sufficient water sources can be identified the local water resources could be used if sufficient yield is likely to be available. However local community water resources will not be used without the permission of the local authority. In the even that there is insufficient water available locally for the works the contractor must make alternative arrangements. 179. Measures to mitigate the adverse impact on water resources and surface drainage patterns have been incorporated into the other drainage mitigation measures. 180. The contractors will carry out the following measures to mitigate the impact of using local community water resources, and the impacts on rivers, where required: i) In all areas availability of water will be assessed to evaluate the impact on community resources. Project water will be brought in by tanker as necessary without depleting local village supplies. ii) Camps will be located at least 500m away from the nearest local settlement to prevent the contamination of community-owned water resources. iii) The contractors will be required to maintain close liaison with local communities to ensure that any potential conflicts related to common resource utilization for project purposes are resolved quickly. iv) Guidelines will be established to minimize the wastage of water during construction operations and at campsites. v) The use of river bed for construction materials will be avoided and minimized. vi) Confine winning river materials to 20% of river width in any location and keep away from river banks. vii) Reinstate river banks if necessary. viii) Re-provision irrigation channels affected by works two weeks before commencement of works to satisfaction of ESO in PPMU (assisted by PCC) and local community. ix) All irrigation canals along the alignment shall be clearly marked on the ground to prevent accidental dumping of fill materials into these canals; x) In case of obstruction or damage, irrigation ditches and ponds shall be cleaned or repaired immediately.
Page 51
17. Construction camps and canteen facilities 181. The contractors will adopt good management practices to ensure that fuels and chemicals, raw sewage, wastewater effluent, and construction debris/scarified material is disposed of in controlled conditions to reduce the risk of contamination. The proposed measures include: i) Worker camp location and facilities located at least 500m from settlements and agreed with local communities and facilities approved by PSC and PPMU and managed to minimize impacts. No project facilities (construction camps, workers’ camps, etc.) will be established within Dong Van Karst Plateau Geopark unless: a) prior approval is obtained from DVKPGMB and UNESCO, and b) such activities will not cause negative impacts on the protected geological resources and landscape within DVKPG. ii) Construction camp(s) will be established in areas with adequate drainage in order to prevent water logging at the camp and formation of breeding sites for mosquitoes in order to facilitate flow of the treated effluents. iii) Potable water, clean water for showers, hygienic sanitation facilities/toilets with sufficient water supply, worker canteen/rest area and first aid facilities will be provided. Separate toilets shall be provided for male and female workers. iv) Hire and train as many local workers as possible. v) Provide adequate housing for all workers at the construction camps and establish clean canteen/eating and cooking areas. vi) Portable lavatories (or at least pit latrines in remote areas) shall be installed and open defecation shall be prohibited and use of lavatories encouraged by cleaning lavatories daily and by keeping lavatory facilities clean at all times. vii) Wastewater effluent from contractors’ workshops and equipment washing- yards will be passed through gravel/sand beds and all oil/grease contaminants will be removed before discharging it into natural streams. Oil and grease residues shall be stored in drums awaiting disposal in line with the agreed WMSDP. viii) Predictable wastewater effluent discharges from construction works shall have the necessary permits from DONRE and local authorities before the works commence. ix) Borrow pits and natural depressions with pre-laid impervious liners will be used to dispose of scarified/scraped asphalt, and then covered with soil. This will check potential groundwater contamination. Options for completely or partially recycling scraped scarified materials will also be taken into account. x) As much as possible, food shall be provided from farms nearby or imported to the area. Bush meat supplies banned to discourage poaching. Solid and liquid waste managed in line with Waste Management Plan. xi) Use of guns and hunting equipment by workers will be banned and dismiss workers taking or using green timber or hunting or in possession of wildlife. xii) Camp site will be cleaned up to the satisfaction of and local community after use. xiii) All waste materials shall be removed and disposed to disposal sites approved by local authorities xiv) Land used for campsites shall be restored to the original condition as far as practicable and the area shall be planted with appropriate trees / shrubs as soon as practicable after it is vacated and cleaned.
18. Sanitation and Disease Vectors 182. Potential sanitation and impacts from disease will need to be controlled by maintaining hygienic conditions in the worker camps and implementing the social and health programmes for the Project. The contractor will ensure that:
Page 52
i) Measures to prevent malaria shall be implemented (e.g., provision of insecticide treated mosquito nets to workers, installation of proper drainage to avoid formation of stagnant water, etc.). ii) Standing water will not be allowed to accumulate in the temporary drainage facilities or along the roadside, to prevent proliferation of mosquitoes. iii) Temporary and permanent drainage facilities will be designed to facilitate the rapid removal of surface water from all areas and prevent the accumulation of surface water ponds. iv) Malaria controls and HIV-AIDS education will be implemented in line with social programmes and plans for the project. v) HIV/AIDS awareness and prevention program shall be implemented in line with social plans.
19. Safety Precautions for Workers 183. Worker occupational health and safety is generally governed by the Labour Code of Viet Nam, Decree 06/CP (20 Jan 1995), Decree / 202 ND-CP OP (27 Dec 2002) and Circular 13/ BYT 24 Oct 1996). A Worker and Public Safety Plan (WPSP) will be prepared by the PCC to establish routine safety measures as required by Labor Code of Viet Nam and by good engineering practice and will include provisions for first aid facilities. 184. Mitigation measures to be implemented by contractors to ensure health and safety of workers are as follows: (i) At least one month before construction commences the contractors will demonstrate to PPMU that the WPSP will be properly resourced and a qualified safety officer will be identified by the contractors in the bid. (ii) The contractors will conduct of training (assisted by PCC) for all workers on safety and environmental hygiene at no cost to the employees. The contractor will instruct workers in health and safety matters as required by law and by good engineering practice and provide first aid facilities. (iii) The contractors will instruct and induct all workers in health and safety matters (induction course) including construction camp rules and site agents/foremen will follow up with toolbox talks on a weekly basis. Workforce training for all workers starting on site will include safety and environmental hygiene. (iv) Fencing on all areas of excavation greater than 1m deep and sides of temporary works shall be observed. (v) Workers shall be provided with of appropriate personnel safety equipment such as safety boots, helmets, gloves, protective clothes, breathing mask, goggles, and ear protection at no cost to the workers. (vi) Ensure reversing signals are installed on all construction vehicles. 185. The contractors will implement the following measures for workers’ safety: i) Instruction and induction of all workers in health and safety matters, including railway safety as necessary. ii) Provision of potable water supply in all work locations. iii) Establishment of safety measures as required by law and by good engineering practice and provision of first aid facilities. iv) Fencing on all excavation, borrow pits and sides of temporary bridges. v) Providing to all workers appropriate personal protective equipment (PPE) such as safety shoes, hard hats, safety glasses, ear plugs, gloves, etc. vi) Scheduling of regular (e.g. weekly tool box talks) to orientate the workers on health and safety issues related to their activities as well as on proper use of PPE.
Page 53
vii) Where worker exposure to traffic cannot be completely eliminated, protective barriers shall be provided to shield workers from traffic vehicles. Another measure is to install channeling devices (e.g., traffic cones and barrels) to delineate the work zone. viii) Construction camps shall be provided with toilets/sanitation facilities in accordance with local regulations to prevent any hazard to public health or contamination of land, surface or groundwater. These facilities shall be well maintained and cleaned regularly to encourage use and allow effective operation. 186. Facilities for workers and public safety, construction site offices and canteen will be regulated in line with the Labor Code of Viet Nam. Complaints will be monitored and investigated and mitigation measures will be revised and the SEMP will be updated as necessary if unexpected impacts occur. All measures related to workers’ safety and health protection shall be free of charge to workers. The occupational health and safety plans to be submitted by the contractor before construction commences can be extended to cover public safety and approved by PPMU assisted by PCC.
20. Public Safety 187. Public safety, particularly of pedestrians and children can be threatened by the excavation of the trenches for side drain construction. Fencing will be installed prior to excavation work commencing on all sides of temporary excavations. The plans will include provisions for site security and guards, trench barriers and covers to other holes and any other safety measures as necessary. The contractor will provide warning signs at the periphery of the site warning the public not to enter and define this in the SEMP. The contractor will restrict the speed of project vehicles and also control traffic by contra- flow and provide flag men and warning signs at either end of the works where the traveling lanes must be temporarily reduced. The contractors will implement the following safety measures for the public: i) Barriers (e.g., temporary fence), shall be installed at construction areas to deter pedestrian access to the roadway except at designated crossing points. ii) The general public/local residents shall not be allowed in high-risk areas, e.g., excavation sites and areas where heavy equipment is in operation and these sites will have a watchman at the entrance to keep public out. iii) Speed restrictions shall be imposed on Project vehicles and equipment traveling within 50m of sensitive receptors (e.g. residential, schools, temples, etc.). iv) Upon completion of construction works, borrow areas will be backfilled or temporarily fenced, awaiting backfilling. v) Provisions for site security, trench barriers and covers to other holes and any other safety measures as necessary. vi) Provide warning signs at the periphery of the site warning the public not to enter and define this in the WPSP. vii) Strict imposition of speed limits along residential areas and where other sensitive receptors such as schools, hospitals, and other populated areas are located. viii) Educate drivers on safe driving practices to minimize accidents and to prevent spill of hazardous substances (fuel and oil) and other construction materials during transport. 188. The contractors will provide information boards near the work sites to inform and instruct the public on how to conduct themselves and to be aware of their surroundings if they must approach the works. The Public Safety section of the Worker and Public Safety Plan will include but not necessarily be limited to the following: i) Statement of contractor’s safety policy for Workers and Public. ii) Legal requirements (e.g. Labour Code of Viet Nam, Decree 06/CP 1995, Decree / 202 ND-CP OP 2002 and Circular 13/ BYT 24 Oct 1996).
Page 54
iii) Works safety issues and public safety issues. iv) Training the workforce and informing the public on works safety issues. v) Establishment and monitoring of acceptable working practices to protect safety. vi) Common concerns with traffic and road safety (e.g. traffic flow/delay requirements). vii) Discussion of the PSC, PCC/PMU inspection/monitoring role. viii) Establishment of complaints management system for duration of the works ix) Agreement on publicity/public consultation requirements. x) Reporting of accidents. xi) Complaints management.
21. Traffic Management 189. Construction activities on the Project road are likely to cause hindrance in traffic flow if not mitigated properly. A Temporary Traffic Management Plan (TTMP) will be developed by the PCC during detailed design phase and its provisions will be implemented by the contractors during construction phase. The main objectives of the plan shall be to maximize the safety of the workforce and the traveling public. The main secondary objective will be to keep traffic flowing as freely as possible. The TTMP will include consideration of the following: i) Lane availability and minimizing interference with traffic flows past the works site. ii) Establishment of acceptable working hours, constraints and public safety issues. iii) Agreement on time scale and establishment of traffic flow/delay requirements. iv) Programming issues including the time of year and available resources. v) Discussion of the PSC, PCC/PPMU inspection/monitoring role. vi) Establishment of complaints management system for duration of the works vii) Agreement on publicity/public consultation requirements (advance signing etc.). 190. The contractors shall implement the following mitigation measures: a. Implement provisions of the TTMP and awareness program for road and rail traffic. b. Communicate to the public through local officials regarding the scope and schedule of construction, as well as certain construction activities causing disruptions or access restrictions. c. Coordinate with local traffic authorities to implement appropriate traffic diversion schemes to avoid inconvenience due to project operations to road users, ensure smooth traffic flow and avoid or minimize accidents, traffic hold ups and congestion. d. In coordination with local traffic officials, schedule transport of materials to avoid congestion, set up clear traffic signal boards and traffic advisory signs at the roads going in and out the road and bridge construction sites to minimize traffic build-up. e. Provide safe vehicle and pedestrian access around construction areas. f. Installation of bold diversion signs that would be clearly visible even at night and provide flag persons to warn of dangerous conditions; 24hrs if necessary. g. Provide sufficient lighting at night within and in the vicinity of construction sites. h. Designation of traffic officers in construction sites.
22. Archaeological and cultural artifacts. 191. Viet Nam has a rich archaeological heritage although no major archaeological site has been identified within 100m of Project roads. Therefore the contractor will take the following precautions to avoid disturbance of any as yet undiscovered archaeologically valuable artifacts. i) Site agents will be instructed to keep a watching brief for relics in excavations.
Page 55
ii) Should any potential items be located, the PSC and ESO will immediately be contacted and work will be temporarily stopped in that area. iii) The ESO will inform the PSC and with the assistance of the PCC determine if that item is of potential significance. If it is so an officer from the Department of Culture and Information (DCI) will be invited to inspect the site and work will be stopped to allow time for inspection. iv) Until DCI has responded to this invitation work will not re-commence in this location until agreement has been reached between DCI, PSC and PPMU/PCC as to any required mitigation measures, which may include structured excavation.
23. Enhancements 192. Environmental enhancements such as tree planting near the road will be explored in the detailed designs and included in the Tree-cutting and Replanting Plan. Enhancements shall be re-assessed prior to construction and proposed enhancements should be discussed by the contractors with the local population to identify stewardship of any planting and also to serve as a vehicle for further public consultation at the implementation stage and to assist in public relations. Environmental enhancements introduced in the detailed designs may include tree planting. The panted specimens should be maintained and monitored for three years after planting to ensure their survival in line with the Tree-cutting and Replanting Plan
C Operational Phase 193. During the operational phase of the Project the Provincial Department of Transport (PDOT) will maintain the roads. 194. The improvement of the hard shoulders on road the Project roads and the improvement of the asphalt surfaced roads can be expected to reduce road traffic noise and air pollution from dust. The improvement of the Project roads road will be within the existing corridor keeping vehicles away from sensitive receivers and at this stage it is difficult to see that any residences or commercial premises or schools will still be close enough to the the Project roads road to be affected by noise and dust so as to exceed the assessment criteria.
1. Noise 195. The Viet Nam the ambient noise standard (TCVN 5949-1998) is Leq60dB(A) for residential sensitive receivers and World Bank criterion is (Leq55dB(A) for residential. school and hospital sensitive receivers. The TCVN criterion is more than 8dB(A) above the existing measured noise levels outside the towns. The main noise source in most areas is traffic nose and in order for the existing background to be exceeded by +8dB(A) the existing traffic would have to be more than quadrupled. Traffic forecasts indicate that traffic is not expected to quadruple for at least twenty years. Therefore the project is believed to be sustainable in terms of road traffic noise. No operational mitigation measures are required.
2. Gaseous Emissions 196. Vehicle emissions (gaseous) as indicated concentration of oxides of nitrogen will be the main air pollution sources during operation. There will be few other sources of emissions near the the Project roads road other than from domestic fuel burning. Sensitive receivers are set far enough back from the the Project roads road to allow adequate dispersion that there will be no significant impacts at the sensitive receivers.
3. Particulate Emissions 197. Vehicle emissions (particulate contamination) such as dust and fumes will also be air pollution sources during operation however toxic residues from vehicle emissions
Page 56
near the the Project roads road are unlikely to accumulate or create significant impacts under the local conditions. Dust from the existing road will be reduced due to the better asphalt surface for the new road. Therefore the project is believed to be sustainable in terms of gaseous and particulate emissions and no operational mitigation measures are required.
4. Soil Erosion 198. Soil erosion will be prevented by developing a comprehensive suite of engineering controls in the detailed designs to prevent and maintain erosion. A system will be devised and engineered to control erosion and flooding on either side of the embankments in case of heavy rains. Apart from affecting the community lands and resources, this would otherwise cause natural streams and irrigation channels to become silted. 199. Measures will also be taken during the operational phase to ensure that storm drains and highway drainage systems are periodically cleared to maintain clear drainage to allow rapid dispersal of storm water flow. An adequate system of monitoring, reporting and maintenance will be developed.
5. Driving Conditions and Community Safety 200. The rehabilitation and widening of the the Project roads road is likely to increase the vehicle speed on the road. Increases in traffic flow indicate additional future traffic should be moderate and unlikely to create many community safety issues. Overall the condition of the road facilities will be enhanced and driving conditions should improve. Routine safety measures, signage and road markings should be introduced to reduce driving risk further in accident prone areas and provide enhancements to driving conditions.
6. Tree planting 201. . Environmental enhancements introduced in the detailed designs may include tree planting, as necessary. The panted specimens should be maintained and monitored for three years after planting to ensure their survival in line with the Tree-cutting and Replanting Plan
7. Water Resources 202. Complaints about the contractors’ works will be resolved in the construction phase. The scale of the works indicates that there are unlikely to be any impacts that continue into the operational phase.
D Cumulative Environmental Impact Associated with the Project Locations 203. There should be no significant adverse cumulative impacts expected from the roads in TCNMP. Overall the improvement in the road system and Viet Nam will potentially lead to growing traffic, commercial activities, that may indirectly lead to additional pollution. It is not possible to quantify these impacts at this stage. However the TCNMP will be carried out on existing roads and there is not likely to be any significant change to the current pattern of movements caused by road upgrading that could potentially lead to uncontrolled access for exploitation of minerals or forest resources. The statutory provisions under the laws of Viet Nam cover pollution control, the forestry protection acts cover exploitation of forest products and there are also laws to protect wildlife in both countries. These laws are established but institutional strengthening is required and improvements in resources are needed to achieve better enforcement to support strategic management of pollution control and resource exploitation in the long term. 204. The Project roads are a part of an already well developed network and although the TCNMP will increase traffic gradually there will be other benefits in improved traveling conditions and vehicle cost savings that will off set the traffic impacts.
Page 57
VI. INFORMATION DISCLOSURE, CONSULTATION AND PARTICIPATION
205. The objectives of the stakeholder consultation process was to disseminate information on the project and its expected impact, long-term as well as short-term, among primary and secondary stakeholders, and to gather information on relevant issues so that the feedback received could be used to address these issues at early stages of project design. Another important objective was to determine the extent of the concerns amongst the community, to address these in the project implementation and to suggest appropriate mitigation measures.
A Identification of Stakeholders 206. Stakeholders are people, groups, or institutions that may be affected by, can significantly influence, or are important to the achievement of the stated purpose of a proposed intervention. The stakeholders consulted for the stretch of the subject Project road included individuals representing 60 persons from 20 family groups in 7 villages in the two districts that the Project roads run through. These were considered to be representative of the community living in the area, the road users, the business associated with the road and the locally elected representatives. Consultations took place in September 2009 and July 2010. Dates and locations are presented in Appendix B.
B Consultation with Stakeholders 207. The results of the public consultations are recorded in Appendix B. The main environmental concerns included protecting water supplies, preventing damage to local electricity cables and other infrastructure and utilities surroundings construction areas. Prompt completion of the works and minimization of land acquisition were also requested by many local stakeholders. Increased traffic noise and controlling project workers and sanitation during construction were also concerns. Full and prompt compensation for land acquisition was also raised as a social issue. No significant operational phase impacts were identified and the communities along the Project roads indicated they would fully support the rehabilitation Project. The affected persons also fully expect that the necessary arrangements to compensate loss of property are addressed before construction commences. Results are summarized broadly in Table VI.1. Further information is provided in Appendix B.

PMU should discuss compensation with local To be addressed in the Resettlement Plan people. * In many cases the interviewees were at first reluctant to discuss. The concerns are inferred from the replies in the field .
C Concerns Addressed 208. Concerns with respect to road alignment and drainage design and the disturbance or destruction of crops and gardens, private property and community disturbance have been brought to the attention of the project proponent and the relevant parties are well aware of the potential for local disturbance that can result from poorly controlled contractors. The main issues raised are addressed in the environmental management plan, as far as is reasonably practicable at this stage; a resettlement plan has been prepared to compensate for affected persons that can reasonably be predicted at this stage. Unforeseen impacts will also be captured by the requirements to update the environmental management plan and inform ADB in response to any unpredicted impacts that arise periodically as necessary. 209. The objectives of the stakeholder consultation process was to disseminate information on the Project construction and the expected impact, long-term as well as short-term, among primary and secondary stakeholders, and to gather information on relevant issues. Another important objective was to determine the extent of the concerns amongst the community, to address these in the project implementation and to suggest appropriate mitigation measures. The feedback received has been used to address these issues at early stages of project design.
D Information disclosure and Participation 210. Concerns have been expressed that the SC should disclose the road construction works in advance and complaints monitoring will provide further opportunities for consultation and can assist in public participation. Providing information through local authority offices will provide a conduit for the improvement of the project implementation to better serve the stakeholders. Public consultation can also assist in i) harnessing cooperation from informed people to help local authorities reconfirm the extent of local permits and licenses that will be required at a later stage; ii) obtaining cooperation from informed residents and groups which to avoid cost and time in dealing with complaints; iii) identifying local infrastructure projects or other local initiatives that will interface with the Project roads with assistance from informed local authorities; iv) the collection of anecdotal information on the current condition of the local environment including aspects of forest and wildlife and conservation. 211. The environmental assessment process under the SPS 2009 requires the disclosure of the IEE to the public during the completion of the IEE to be in strict adherence to the rules. This process will be concluded by displaying the IEE at the PPC Headquarters during the period when the IEE is disclosed on the ADB website
Page 59
VII. GRIEVANCE REDRESS MECHANISM
212. Existing arrangements for redress of grievances for affected persons are through complaints to the village and commune committees up to the district level and then through the PPC and back to the agency (e.g. PDOT/PPMU) that implements a project. This indirect route will remain in place to preserve the usual administrative remedies. There will be a need to deal with complaints and grievances during construction for this project, Therefore another mechanism will be available to affected persons whereby complaints can also be made direct to the PPMU (with the usual authorities PPC being kept informed). 213. Through a Grievance Redress Committee (GRC), PPMU shall promptly address affected people’s concerns, complaints, and grievances about the Project’s environmental performance at no costs to the complainant and without retribution. The GRC, which shall be established by PPMU before commencement of site works, shall be chaired by PPMU and shall have members from the contractor, ward and district committees, DONRE, local NGO, and women’s organization. Grievances can be filed in writing or verbally with any member of the GRC. The committee will have 15 days to respond with a resolution. If unsatisfied with the decision, the existence of the GRC shall not impede the complainant’s access to the Government’s judicial or administrative remedies. 214. PPMU shall make public the existence of this grievance redress mechanism through public awareness campaigns. PPMU shall also set-up a hotline for complaints and the hotline shall be publicized through the media and numbers placed on the notice boards outside the site and suggestion/complaints boxes be placed outside the construction camps and yards as well as on notice boards outside the Ha Giang provincial offices near the Project roads. Locally affected people will still be able to express grievances through the ward or district committees and these would be referred to PPMU through the usual channels in those committees. 215. The GRC will develop and maintain a database of all complaints received related to the Project and actions taken to resolve complaints, disputes or questions about the Project. It is also proposed that a hotline to PPMU/ESO be set up for complaints and that the hotline is publicized through the media and numbers placed on the notice boards outside the Ha Giang provincial offices near the Project road. The JCC and PPMU shall publicize the existence of the grievance redress mechanism through public awareness campaigns.

VIII. ENVIRONMENTAL MANAGEMENT PLAN
A Implementation Arrangements 216. In Viet Nam the environmental regulations of GOV are derived from the Law on Environmental Protection (2006) and subsequent decrees and regulations. The environmental assessment rules are set out in the Guidelines on Implementation of Law on Environmental Protection 2006 (under Law on Environmental Protection 2005) that requires Environmental Impact Assessment (EIA). DONRE will review the IEE and before construction can commence. 217. The project owner (PPC/PPMU) is required to obtain approval from the Ministry of Natural Resources and Environment (MONRE) following environmental assessment and public consultation. It has been clarified by MONRE that although the Guidelines on Implementation of Law on Environmental Protection 2006 applies the PPMU should disclose the scale and scope of the Project works at the detailed design stage so that DONRE can decide on procedures that need to be completed under the environmental laws in view of the pending developments in environmental assessment procedures in Viet Nam. Therefore PPC/PPMU will submit the IEE to DONRE to disclose the scale and scope of the projects in due course and obtain approval. 218. Pollution standards for the protection environment are described in the Law on Environmental Protection (2006). The following standards will be referred to for water quality, noise, dust monitoring during implementation of the Project: QCVN 08:2008/BTNMT (surface water quality), QCVN 05:2009/BTNMT (air quality), and TCVN 5949:1998 (noise). Certain associated project activities commonly associated with road improvement such as quarry operations, extraction of gravel or discharge of waste water also require licenses that are issued at the provincial level depending on the duration and scale of those activities. DONRE is the authority to decide on the permit requirements at the provincial level. The table below defines the responsibilities for EMP implementation. 219. During project implementation, the joint coordination committee (JCC) will engage one (1) international environment specialist and two (2) national environment specialists to undertake PCC’s tasks with regard to EMP implementation and monitoring (see Table VIII.1) for the six Project provinces (Lao Cai, Yen Bai, Bac Kan, Cao Bang, Tuyen Quang and Ha Giang) . The estimated cost for engaging these specialists and other expenses related to EMP implementation are presented in Table VIII.3. 220. The PPMUs will engage national project supervision consultants (PSC). Included in the PSC’s responsibilities (Table VIII.1) is to ensure that the contractors implement the provisions of the Project EMP and SEMPs.

C Environmental Monitoring
1. Compliance Monitoring 223. Table VIII.2 above also shows the program for monitoring the compliance on various provisions of the EMP during pre-construction, construction and operation phases. PCC needs to implement a number of measures during detailed design phase (e.g., incorporation of environmental design measures into the detailed design, preparation of method statements/SEMPs, etc.) and this will be confirmed by PPMU to ADB. During construction, most of the mitigation measures shall be implemented by the contractors and their environmental performance, in terms of implementation of such measures, shall be monitored by PCC. The timing or frequency of monitoring is also specified in Table VIII.2. During operation EMP implementation shall be the responsibility of PDOT. i) Design Stage 224. PPMU shall ensure that EMP measures for the design stage are incorporated in the detailed design. The effective incorporation of the EMP in the civil works contracts shall also be ensured be by PPMU with assistance from PCC and this, along with implementation of EMP provisions, shall be audited by ADB as part of the loan conditions. 225. Prior to implementation of the Project the IEE and EMP will be updated and amended, as necessary, by PCC after the detailed designs are complete and contracting arrangements are known. Such updating shall be based on reconfirmation and any additional information on the assumptions made at this feasibility stage on location scale and expected conditions of the Project. For example, in this case if there is additional land required (although not confirmed as yet) the designs may be amended and the environmental significance must be reviewed. Although no major additional impacts would be anticipated based on the information provided to date, the performance and evaluation schedules to be implemented during project construction can be reviewed, updated, and costs estimates can be revised if necessary. ii) Pre-construction Stage 226. Implementation of construction of the Project will need to comply with environmental requirements and clearance that has been obtained from DONRE for the whole Project at a provincial level for any statutory environmental assessment or an indication that no further assessment is required. PCC will also need to confirm that Contractor(s) and their suppliers have complied with all statutory requirements for permits from DONRE and provincial authorities. PCC shall also check that Contractor(s) have all the necessary valid licenses and permits for use of powered mechanical equipment if necessary and the use of local water supplies (and to construct or operate plant such as for cement batching or asphalt/bitumen (if required) in line with all environmental regulations and permit conditions from provincial authorities. (N.B. local suppliers of cement and bitumen will be preferred if practicable). iii) Construction Stage 227. The PCC shall undertake regular monitoring of the contractor’s implementation of mitigation measures specified in the Project EMP and SEMPs. Likewise, as part of its day to day project supervision, the PSC shall ensure that contractors comply with the Project EMP and SEMPs. iv) Operational Stage 228. PDOT shall implement the EMP mitigation and monitoring requirements during operation such as monitoring of erosion control measures, survival of planted trees, etc.
Page 96
Accidents along the Project roads shall also be monitored as basis for implementation of mitigation measures to improve road safety.
2. Environmental Effects Monitoring 229. As shown in Table VIII.3, PCC shall undertake baseline environmental monitoring for air quality, noise and surface water quality. One-time sampling shall be conducted prior to start of site works at the specified locations. During construction, PCC shall undertake quarterly monitoring of surface water quality and semi-annual monitoring of air quality and noise in the same locations sampled during pre-construction. Additional sampling occasions shall be carried out and additional parameters shall be analyzed (as necessary) to validate complaints and/or investigate pollution events caused by the project.
D Reporting 230. SC/PPMU shall submit the following environmental monitoring reports to ADB: 231. Baseline Monitoring Report: The results of baseline data collection carried out by PCC on air quality, noise and surface water quality (as specified in the EMP) shall be submitted to ADB prior to commencement of civil works. 232. Environmental Monitoring Reports: Environmental monitoring reports shall cover the status of EMP implementation in terms of required mitigation measures for different project phases, results of environmental effects monitoring (air quality, noise and surface water quality), necessary remedial actions to effectively address negative environmental impacts due to project implementation, status of environmental capacity building activities as well as documentation of complaints received and corresponding action/resolution. The environmental monitoring reports will be submitted to ADB semi- annually during the construction period and annually for two years after completion of construction.

E Capacity Building 233. In Viet Nam, the environmental assessment process is established but environmental awareness and capability for implementation of EMP in infrastructure projects of both the executing agency (PPC) and the implementation agency (PPMU) are limited and in development. There is no staff with direct responsibility to bring environmental issues to the notice of senior management. The status quo is that in PPMU is that engineering officers may be delegated to check environmental matters on an ad hoc basis. There is no capacity to check the adequacy of the Project EMP or SEMPs. The IEEs and EMP are referred to the environmental department in DONRE for approval. The environmental department in MOT is not directly involved with project implementation. In the long term it is recommended that a new environmental management unit should be set up to improve this capacity in the PPMU in PDOT that could work with the various environmental and forestry agencies as required. 234. The most significant challenge is the lack of human and financial resources and necessary infrastructure. To address this constraint, PDOT/PPMU will designate a full time staff as environment and safety officer (ESO) to handle the environmental aspects of the Project during implementation stage. The ESO and other relevant staff of PPMU and PDOT will be trained by the environment specialists of the PCC based on the indicative terms of reference presented in Table VIII.5. 235. The requisite ESO staff in PPMU should be delegated prior to the commencement of the tendering for the detailed design activities in order to work full time with PCC to ensure the inclusion of environmental requirements can be translated into contractual works for completion also respond to unexpected circumstances. The PCC environmental specialists can then train the environmental officers (ESO) in PPMU “on the job”. The ESO can initially fall back on assistance from PCC as they develop experience. 236. The PCC will also conduct workers’ orientation on Project EMP and SEMP provisions. Such orientation shall be periodically conducted by the PCC as every new contractor is engaged. The ESO in PPMU can take over this role as they develop capacity. 237. The table below shows the indicative terms of reference for the environmental management capacity building activity to be conducted by PCC for PPMU and PDOT staff tasked to oversee EMP implementation.

IX. CONCLUSIONS AND RECOMMENDATIONS
238. This IEE concludes that the construction impacts will be manageable if the mitigation measures are implemented thoroughly. The EMP is based on the type, extent and duration of the identified environmental impacts. The EMP has been prepared by close reference to best practices and in line with SPS. 239. This IEE study was carried out when the Project roads were at the initial stage of design during the TA 7245 (VIE). Secondary and primary data were used to assess the environmental impacts in a comprehensive manner and public consultation and route reconnaissance were carried out in order complete the environmental assessments and recommend suitable mitigation measures. The IEE report provides a picture of potential environmental impacts associated with the upgrading of the Project roads and suitable mitigation measures have been recommended. The EMP will be reviewed by the PCC as a basis for preparing SEMPs. Both Project EMP and SEMPs will be included in bidding documents for civil works. In the event that any design details for the locations or scope of the Project roads are changed, the IEE and EMP shall be reviewed and revised accordingly and submitted to ADB for review and clearance. 240. The upgrading of the Project roads offers a robust option for the enhancement of the existing road network. Several actions are required during the detailed design stage to minimize impacts to acceptable levels. The negative environmental impacts from the rehabilitation will mostly take place during the construction stage. The construction impacts should be very predictable and manageable and with appropriate mitigation few residual impacts are likely. Additional human and financial resources will be required to improve environmental capability and to progress and achieve necessary statutory compliance and environmental clearance certification for the Project roads or associated activities that also require environmental permits under the environmental laws of Viet Nam. 241. The responsibilities for the implementation of mitigation measures and the parities responsible will be clearly defined in contracts and agreements and the implementation by various parties will be monitored by PPMU with assistance from PCC and PSC. 242. Most of the anticipated environmental impacts related to the the Project roads will take place during the construction phase, there are no identifiable cumulative impacts during operation. The implementation of the environmental mitigation measures during the construction period shall be the responsibility of the contractors and shall be closely monitored by the PSC and PCC and these requirements will be included in contracts. PDOT will maintain the road and shall undertake the appropriate operational mitigation measures for maintenance during the lifetime of the Project roads. 243. Whereas the implementation of the environmental mitigation measures during the construction period will be assigned to the contractors, experience suggests that contractors may have little impetus or interest to deal with environmental problems in the absence of performance linked criteria. Therefore, the required environmental mitigation must be clearly described in the contract documents at the bidding stage and environmental performance and the completion of mitigation should be linked to payment milestones in the contracts. 244. Contractor environmental awareness training will undertaken by the PCC and this can assist PPMU to develop environmental awareness at all levels. It will require sustained effort over several years to achieve proactive management of environmental responsibilities but TCNMP and other previous ADB projects have also included provision to consolidate this process and over time so that environmental improvements can accrue in line with good sustainable practice and ADB guidelines. The ESO in the PPMU will be supported in the short term by the PCC who will be able to liaise with and advise the PPMU to better utilize the available staff resources to support environmental management. This capability can be used to extend environmental awareness for the
Page 102
contractors in the short term. In the medium to long term PPMU can strengthen the support their environmental management and dovetail the efforts with the environmental officers in MOT. At the completion of the TCNMP the environmental officers in PPMU will be retained in PPMU and their environmental obligations could be more easily taken up for more ambitious projects in future. 245. The construction is restricted to the existing road corridor and as far as can be ascertained at this stage the will be some small areas of land required where there road geometry is improved but these areas will generally be small and there is not likely to be any significant additional land required to complete the construction. However, it is possible that some additional land may be required at the detailed design stage. A resettlement plan and resettlement framework have been prepared to establish policies and procedures for payment of compensation to affected people for lost or damage assets. The scope of land acquisition impacts, where they occur, will be limited to the areas of the road where the geometry needs to be adjusted and in thee areas there will be some displacement of housing and affected people will experience small losses of crops, trees, fences or other secondary structures. 246. Environmental impact and compliance monitoring activities will focus on compliance with license conditions and EMP provisions, recording implementation of mitigation measures, recording environmental parameters, reviewing contractor environmental performance and proposing remedial actions to address unexpected impacts and complaints. 247. The EMP and SEMP prepared for the Project, will be used as a basis for an environmental compliance program in a regular programme of environmental monitoring and auditing. In addition, any conditions included as part of the environmental compliance from the Government (MONRE/DONRE) will also be included as a basis for the environmental monitoring and compliance program. Therefore, continued monitoring of (i) the implementation of mitigation measures, (ii) the implementation of the conditions of environmental compliance and (iii) the environmental impact related to the maintenance of the Project roads will be carried out regularly as scheduled in the EMP. Environmental monitoring reports will be submitted semi-annually by PPMU to ADB. 248. The IEE report is prepared based on the preliminary designs for rehabilitation and upgrading proposals along the specified routes. At the implementation stage, PPMU through PCC will make arrangements to monitor the schedules of mitigation measures and conduct of environmental effects monitoring activities specified in the EMP. With these measures in place, environmental impacts of the Project should be manageable and will not result in any residual impacts which are above accepted environmental standards. No further or additional impact assessment is considered necessary at this stage. .
