I. INTRODUCTION
A. Report Purpose and Rationale
1. As defined in the Summary Initial Environmental Examination (SIEE)1 for the Tongi- Bhairab Bazar Double Line Project as the selected sample subproject for the Bangladesh Railway Sector Improvement Project under ADB Loan, semi-annual environmental monitoring reports (EMR) have to be prepared by the borrower in order to evaluate and assess overall project activities to ensure the effective implementation of the Environmental Management Plan (EMP).
2. The purpose of this second EMR is to document the environmental management activities and compliance with the approved EMP for the period between November 2012 and 31st August 2013. This report is prepared in accordance with the environmental monitoring program as defined in the EMP. As the second EMR, it will only cover the construction phase as the compliance with the EMP for the design, bidding, and construction preparation stages was detailed in the first report to October 2012. In line with targets aimed at reducing the negative environmental impacts of the Project and in accordance with all the relevant specifications and standards of the GOB, as well as the policies of the Asian Development Bank (ADB), this report will emphasize: (i) progress made in implementing the EMP, (ii) implementation of mitigation measures, (iii) Monitoring actions undertaken, as prescribed in the EMP, (iv) environmental compliance and (v) problems that have occurred and corrective actions taken
3. This report is prepared by SMEC International and Associates (SMEC) as the project implementation consultant. The monitoring plan was updated on the basis of discussion with Bangladesh Railway.
B. Sector Objective
4. The Government of the People’s Republic of Bangladesh adopted the National Land Transport Policy (NLTP) in April 2004 following recommendations from DFID and other agencies, through which the Institutional and Operational Capacity of Bangladesh Railway are to be enhanced and improved. Financing to achieve the targets set in the NLTP was to be provided by the Asian Development Bank (ADB), the World Bank and JICA and an umbrella DPP for a cost of BDT 36.01 billion was approved in September 2006.
5. Recognising that the Bangladesh Railway (BR) needed both reform and investment before it could achieve the targets set for the railway sector the GOB requested the ADB to help finance a Railway Sector Investment Program. This financial support from the ADB is being extended through a multitranche financing facility (MFF). The Government committed to implement a Roadmap and Investment Program that consists of two components viz:
The Reform Project to improve the performance of the railway sector through organisational, institutional strengthening & policy reforms;
The Investment Project to finance implementation of priority investments (“Investment Subprojects”) to overcome capacity bottlenecks in areas of the railway network where such investments are both economically and financially viable (e.g. the Dhaka- Chittagong Corridor.)

6. The MFF for the Bangladesh Railway Sector Investment Program was approved by the Board of Directors of the ADB on 15 September 2006 for US$ 430 million. The scope of the MFF includes (i) a Reform component for US$ 30 million of Asian Development Fund (ADF) and (ii) an investment component of US$ 400 million of Ordinary Capital Resources (OCR).
C. Project Inception
7. An umbrella project named “Bangladesh Railway Sector Improvement Project” was approved by ECNEC on 17 September 2006 at a total cost of BDT 36,012.50 million (GOB – BDT 7,202.50 million and PA – BDT 28,810.00 million) under ADB Financing. With the approval of the umbrella DPP implementation of sub-projects named “Construction of Double Track between Tongi and Bhairab Bazaar including signalling” and “Reform of Bangladesh Railway” was commenced. Other sub-projects were to be taken in hand after fulfilment of the 2nd, 3rd and 4th PFR conditions of the ADB loan. A separate DPP for each sub-project is to be prepared on the basis of the appraisal study of the consultants engaged for the implementation of the subprojects. Bangladesh Railway under the Ministry of Railways (formerly the Railways Division, Ministry of Communications) is the Executing Agency of the program
8. The Loan Agreement for the 1st tranche of US$ 130 million was signed with ADB on 15 February 2007 for two loans viz:
- Loan No 2316-BAN; US$ 100 million (OCR) - Loan No 2317-BAN; US$ 30 million (ADF); RSIP Reform Project
Loan No 2316-BAN is financing part of the investment component and was approved as PFR-1 together with the MFF and became effective on 24 April 2007.
9. Loan 2845-BAN for $150 million was approved on 22 December 2011 and finances (i) the cost overrun in the Tongi-Bhairab Bazar double track project; (ii) rehabilitation of yards and extension of loops at different stations in the Darsana-lshurdi-Sirajganj Bazar section; (iii) upgrading of Signalling at 11 Stations between lshurdi and Darsana; and (iv) construction supervision consulting services. The loan agreement was signed on 27th August 2012 and became effective on 5th November 2012.
D. Project Objective
10. The investment component of the Bangladesh Railway Sector Improvement Program will concentrate on enhancing capacity to overcome constraints to increasing rail services in the Dhaka-Chittagong, western corridor to India and other corridors where there is a high demand for intercity passenger and freight (principally container, iron & steel, coal & petroleum products) services. In addition to capacity improvements on the Dhaka-Chittagong corridor, other components include improvement of signal systems and loop lines in the western zone, rehabilitation of bridges and procurement of rolling stock.
11. The total project length was envisioned as 500 km & comprised of 7 sub-projects viz:
(i) Construction of double line between Tongi to Bhairab Bazar; (ii) Partial Financing of construction of chord line from Dhaka to Laksam (iii) Strengthening of Jamuna Bridge for higher axle load; (iv) Line Capacity improvement between Dhaka & Tongi by introducing intermediate block signaling; (v) Upgrade signaling in 14 stations between Ishurdi & Darsana;
Bangladesh Railways Environmental Monitoring Report Ministry of Railways 2 #2 Bi-Annual Report - August 2013 BRSIP:Tongi-Bhairab Bazar Double Line Project – Implementation Consulting Services ADB Loan No 2316-BAN, 2845-BAN
(vi) Rehabilitation of yards and extension of loops at different stations between Khulna to Parbatipur; (vii) Construction of new metre guage line from Bogra to Jamtoil;
12. The construction of the double line between Tongi to Bhairab Bazar (64km) was selected as the “sample” sub-project for loan processing under the MFF as the Tongi-Bhairab Bazar section is common to the Dhaka-Chittagong, Dhaka-Sylhet, Dhaka-Mymensingh (via Bhairab Bazar) and Dhaka-Noakhali Routes. The line capacity is already saturated and it is envisaged that commissioning of the subproject will reduce travel time by rail removing the bottleneck in the section, enhancing passenger services and reduce the risk of train accidents.
E. Project Implementation
13. An International Tender was called for Consultancy Services for the detailed design of the sample subproject and appraisal of the other subprojects. SMEC International Pty Ltd in association with Maunsell/AECOM (NZ), No. 5 Institute of China Railway, Balaji Railroad Systems Ltd (India) and ACE Consultants Ltd (Bangladesh) was the successful tenderer and a consultancy contract was signed on 06 January 2007.
14. The detailed design of the selected subproject viz “Construction of double line between Tongi and Bhairab Bazar including Signalling” (TBDLP) was completed in 2008. Based on the completed design, tender documents were prepared and re-issued to prequalified contractors in April 2010. A contract was signed for the TBDLP between Bangladesh Railway and the China Railway Group Ltd. (CREC) on 27 July 2011 for a Contract Amount of BDT 14,054,202,610 (US$ 202,670,742) of which ADB will finance 94.7%
15. After signing of the contract for the construction works SMEC was appointed the “Engineer” for the construction contract on 11 August 2011. CREC and SMEC mobilised their staff after signing of this contract and the Notice to Commence was issued to the Contractor on 02 November 2011. The total physical construction period in the Contract is 1095 calendar days (36 months) with the Contract Completion Date being 31 October 2014. The works schedule agreed as per the contract has been attached herewith as Appendix1.

II. PROJECT LOCATION AND COMPONENTS
A. Project Location
16. The line from Tongi to Bhairab Bazar passes 14 railway stations and the Project area is administratively located in 3 districts: Gazipur, Narsingdi and Kishoreganj. The rainy season in this area starts between April and July and ends between September and November. The track passes through low, flat and alluvial land and crosses several major rivers viz, Balu, Pipulia Khal, Sitalakha, Arial Khan and Old Brahmaputra and many smaller rivers, streams and canals some of which are dry during the dry season.
Figure 2.1 Project Location Plan
B. Project Components
17. The scope of the Tongi-Bhairab Bazar Double Line Project (TBDLP) and the major project activities are summarised as follows:
(i) Construction of 64 km of main line and 22 km of loops and sidings involving widening of embankment and construction of new embankment for bridge approaches alongside the existing operating main line. The embankment is to be constructed to accommodate future broad gauge (BG) tracks.
(ii) More than 2 million cubic metres of new embankment will be placed along the existing alignment of which approx 20% will be taken from the ROW and the rest from approved and/or designated areas outside of the ROW (mostly via river dredging). Geotechnical Investigations undertaken identified unstable foundation

conditions over 20 km of the length requiring specific soft ground treatment2 to be undertaken during embankment construction.
(iii) Construction of new Metre Gauge (MG) track with 90A rails for the down-line including new loops and sidings at stations involving 64 km of main line and 22 km of loops and sidings. The existing MG track will form the up-line and replacement, realigning & removal of this track (where applicable) will be carried out. Sub-Ballast and Ballast will be provided for the new MG track with 90A rails provided to accommodate heavier loadings. Pre-stressed Concrete (PSC) Sleepers to carry 90A rail will be provided with timber sleepers only where specified. Track laying equipment including 1 Ballast Tamping Machine, 1 Heavy Gang Car & 2 Motor Trolleys for MG track will be supplied by the contractor.
(iv) Construction of 40 new bridges and 31 new culverts will be undertaken. Three bridges fall under The Bangladesh Department of Environment’s (DOE’s) Red category and require full EIAs, while others are in the amber and green category and require lesser types of assessment.. The three red category bridges are:
Br #79 – Km 40+000; length 345 metres – Lakhya River Br #34 – Km 5+000; length 171 metres – Old Brahmaputra Rive Br #63 – Km 22+000; length 122 metres – Arial Khan River
(v) Construction of 10 station buildings, platforms, platform sheds, several foot overbridges and remodelling of station yards;
(vi) Modernisation of signalling systems of 12 stations involving the Supply and installation of computer based interlocking (CBI) signalling system with associated telecommunications facilities at these stations.
(vii) Relocation of overhead electricity wire crossings and underground utility crossings affecting construction works. Construction of 37 Level Crossings including Gate Goomties and Equipment Rooms for Signalling.
(ix) Construction and upgrading of access roads to the stations
18. The following activities will affect the natural environment on varying degrees:
Transportation and stockpiling of construction materials such as embankment fill, cement, sand, aggregates, reinforcing steel, ballast, rails, sleepers, and timber;
Bridge construction may require boring or driving of piles for foundations or temporary works, transportation of heavy precast sections, use of high capacity cranes and lifting equipment and fabrication of steel members at site
Manufacture of sub-ballast and ballast by crushing of rock;
Manufacture and delivery of concrete from central batching plants
Set up and operation of construction work camps
Clearing of station new access roads or widening existing access road alignments.
2 Soft ground treatment includes a variety of engineering methods to induce immediate settlement in embankment materials permitting the embankments to support heavy weights from passenger or freight trains and avoid long-term settlement of the track.

III. ENVIRONMENTAL RESPONSIBILITIES AND INSTITUTIONAL SETUP
A. Environmental Category
19. The project falls under ADB Category B and hence an Initial Environmental Examination (IEE) is sufficient to meet the environmental requirements. An IEE report was prepared by the consultant engaged by the ADB during appraisal. However an updated Environmental Management Plan (EMP) was required during the detailed design stage to serve as guidelines for the Contractor and a means of completing compliance monitoring for the “Engineer”.
20. The recommendations of the EMP were incorporated into the detailed design and the tender documents and have then become a part of the civil works contract. The cost for the implementation of the EMP has been included in the Contract and the approved Revised Development Project Proforma/Proposal (RDPP). The updated EMP was approved by ADB in 2008 and was included in the tender documentation in 2008.
B. Environmental Clearances
21. The initial environmental clearance for the project, valid for one year, was obtained from the DOE on 01 July 2009 vide their memo no DOE/Clearance/4041/2009/223. Subsequently renewal of the environmental clearance certificate was obtained for the years 2010, 2012 (2 years) and 2013. The last environmental clearance certificate up to June 2014 was received on 01 August 2013. These certificates are provided in Appendix 2.
C. Institutional Setup and Responsibilities
22. The Executing Agency for the Project is the Bangladesh Railway represented by General Manager/Project Director TBDLP. The Contractor is the China Railway Group Ltd (CREC) represented by the Contractor’s Representative in Dhaka. The Implementation Consultant is SMEC and Associates represented by the Team Leader/Project Manager who has also been delegated as “The Engineer” under the Contract. The responsibilities of each organisation during the various Phases of the Project are shown in Table 2.1 below.

D. Key Findings in the SIEE report
23. The conclusion and recommendations of the updated EMP of 2008 are as follows:
“Double lining of the Tongi-Bhairab Bazar section track has only nominal impact on Impacted Environmental Components (IECs) because the proposed track passes by the side of existing track. The anticipated impacts can be further reduced if the contractor and other stakeholders adhere to good practice during the implementation stage and duly implement provisions of the EMP and environmental clauses. However, studies recommended below are mainly to generate data under ambient conditions for future monitoring whether or not the subproject really impacts the IECs.
Ambient air pollution data at Tongi, Narsingdi and Bhairab Bazar stations and villages through which the rail track passes at busy and lean hours may be recorded in March. Data on noise pollution at day/night time at busy stations and in densely populated villages through which the track passes may be recorded once a year during February/March. Study on local hydrology, land use pattern, wildlife biology of project impacted area during the operation stage. The Subproject, however, has no serious impact on IECs at any stage of its implementation.
Railway is less land intensive and more energy efficient compared to other modes of transport, hence is more environmental friendly. With introduction of high speed and more energy efficient designs of locomotives, the environmental pollution caused by the transport sector can be substantially reduced. Hence it is recommended that even if there remain any minor residual adverse environmental impacts, development of railway should be give high priority at the planning and policy level as it is by far the most environmentally friendly mode of transport”

IV. PROJECT STATUS
A. Project Status at 31 August 2013
24. The Bill of Quantities (BOQ) for the civil works is sub-divided in to 7 major activities against which works are measured and appropriate payment is made. These activities also formed the basis for the planning and scheduling of the works as represented in the Contractor’s Works Programme (Appendix 1).
25. The Contractor commenced mobilization of his staff in October and November 2011 and physical works commenced on site in December 2011 on the construction of the Engineer’s Offices and provision of temporary works for the major bridge #79 at Km 41+167.
26. Sixty-four km of embankment provides the base formation on which sub-ballast and ballast must be placed before the sleepers and tracks can be laid. Including the embankment, sub-ballast, ballast and topsoil materials, a total of more than 2,700,000 m3 of material will need to be transported and placed. Of that more than 2 million m3 of embankment will be obtained via river dredging. This wet mostly sandy material dredged using suction dredges will be sucked from the river bottoms and conveyed by temporary pipelines to the rail corridor.
27. In addition to these amounts more than 1,000 concrete piles are being placed (bored and cast in place) within rivers, streams and canals for bridge piers and another 1,300 piles will be built on shore and dry land for pier and abutments. Thirty one (31) heavy duty new railway culverts and 40 bridges are being built. Of these bridges three have spans of > 135m. At the major bridge sites high capacity temporary concrete batching plants have been established.
28. The TBDLP also has 11 existing passenger stations where new station buildings, platforms, platform sheds, foot over bridges and access and parking facilities will be constructed with 2 additional equipment buildings to be constructed at existing stations. This work will require the management of tens of thousands of cubic metres of waste building materials, that will need to be sorted, inventoried, recycled and stored.
29. To facilitate these works four offices have been constructed for the Engineer along the alignment and the Contractor has established his construction camps and storage areas for major materials to be used including sub-ballast and ballast, PSC sleepers, rail and associated connection materials, sand and aggregates for concrete manufacture, major track components and other associated equipment and materials.
30. Overall progress up to 31 August 2013 against each of the major activities in the BOQ is shown in the following Table 4.1.

31. Overall Progress of the Project at 31 August 2013 was reported as 50.12% against a target of 53.93% indicating a lag of 3.81%. This level of progress reflects the increase in project activities following the end of the 2012 monsoon season in Oct 2012 and continuing through the 2013 monsoon season commencing in June 2013.
B. Environmental Management Plan
32. The 2006 SIEE contained an Environmental Management Plan (EMP) which in 2008 was updated and included in the bid documentation. At that time the draft EMP was reviewed and considered to be inadequate and various revisions and improvements were made, but did not find their way into the final EMP included in the bid material.
33. In 2011 the Contractor was instructed by the CSC to revise the EMP, making it compliant with 2011-12 safeguard requirements. This requirement was also included in Sub- clause 4.18 of the General Conditions of Contract (GCC) and the Particular Conditions of Contract (PCC).
34. After several revisions by CREC the EMP remained incomplete, specifically lacking clear information on monitoring and timing of mitigation actions. In August 2012, CSC prepared a final
Bangladesh Railways Environmental Monitoring Report Ministry of Railways 9 #2 Bi-Annual Report - August 2013 BRSIP:Tongi-Bhairab Bazar Double Line Project – Implementation Consulting Services ADB Loan No 2316-BAN, 2845-BAN
revision of the EMP (focusing on the construction period) and instructed CREC to implement it. This EMP is included as Appendix 4.
35. The construction contract signed by the Contractor in 2011 also contains more than 100 specific environmental and occupational health and safety clauses (see Appendix 3) which CREC must comply with. All environmental clauses were extracted (as shown in Appendix 3) from the contract documents and given to the contractor in August 2012, reminding the contractor of the environmental commitments which the contractor had signed off on.
C. Environmental Management Implementation Works Schedule (EMWS)
36. In Sub-clause O.8.6 of the Contract Specifications CREC was required to prepare an Environmental Management Implementation Work Schedule (EMWS), expanding on the EMP requirements and defining in a time-bound chart how the mitigation and monitoring measures defined in the latest EMP and the contract clauses would be implemented over the 3-year construction period.
37. This was not satisfactorily completed by the Contractor and therefore a revised EMWS was prepared for the Training and Workshop sessions delivered by the CSC in August 2012 and issued to the Contractor to ensure that the necessary activities would be executed to achieve satisfactory compliance with the EMP. This EMWS is included in Appendix 5.
D. EMP Related Activities
38. Environmental Audit by CSC – 30 Oct – 01 Nov 2012. An environmental audit of the Project was carried out that involved a field inspection of all active worksites and locations where labourers lived as well as the evaluation of all environment-related documentation required of CREC. Given the level of non-compliance and the many letters sent to CREC, immediate actions by the Supervising Consultant were proposed as follows:
“(i) This draft audit report will be submitted to CREC for their written comments to be submitted to the Supervising Consultant by 30th November 2012. CREC will be given until the end December 2012 to fully implement the monitoring program as defined in this audit report, show specific improvements in the areas of occupational health and safety matters by providing weekly written updates and submit a fully compliant October 2012 monthly report. CREC must use this audit report as a guide to the specific improvements needed. (ii) If by the 15th December 2012 a full monitoring cycle is not complete and there is no marked improvement vis-à-vis environmental compliance we will propose that further to this letter and pursuant to GCC 7.5, a final notice shall be sent to the Contractor confirming that “…workmanship is found to be defective or otherwise not in accordance with the Contract…” on the basis of the various omissions recorded in the 01 November 2012 Audit Report. (iii) Accordingly and as provided in GCC 7.6, the Contractor shall be allowed a grace period of 28 days to urgently rectify such omissions and implement the necessary environmental monitoring and mitigating measures to ensure “…the safety of the Works, whether because of an accident, unforeseeable events or otherwise.” (iv) If for whatever reason the Contractor fails to implement the necessary actions on or before the aforesaid deadline, the Employer shall be entitled to invoke the contractual right to “…employ and pay any persons to carry out the work…” and “…the Contractor shall subject to Sub-Clause 2.5 [Employer’s Claims] pay to the Employer all costs arising from this failure.” (v) In addition the Supervising Consultant will recommend that a series of deductions be made from the various items in the BOQ where environmental activities specified in the EMP related to that works item are not carried out satisfactorily. A schedule

39. ADB Review Mission 13-16 Mar 20133 During the ADB Project Review Mission in Mar 2013 the implementation of the EMP was reviewed following a site visit to the Works with the following findings.
“5. …………The Mission visited the site and assessed the progress of the civil works satisfactory, although there are still room for improvement in terms of safety and environmental monitoring. The contractor expressed concerns over the possible delay due to frequent hartals (general strikes) these days. The Mission requested that mitigation measures to cope with the current unrest situation shall be sought, so that negative impact can be minimised.”
“11. Implementation of Environmental Management Plan. Through the site visit, the Mission identified that there is room for improvement in terms of the Environmental Management Plan. In particular the Mission noted that some of the important construction equipment and material on Site were not necessarily stocked and piled up in a proper manner, which may undermine the quality of works. The Mission requested BR and the Contractor for corrective actions. The Mission explained that another loan review focussing on safeguard issues will be planned later this year.”
“12. Compliance with Loan Covenants. The Mission observed that most covenants are being complied with. Details are as per Attachment 2.” Quote from 2013 ADB mission report. Further details relating to Item 12 are included in Part D of Section V of this report following.

V. COMPLIANCE WITH ENVIRONMENT RELATED PROJECT COVENANTS
42. An Environmental Due Diligence Report5 was submitted to ADB at the commencement of the civil works contract in November 2011 along with the 2nd PFR application. The relevant sections of this report are reproduced in this section and updated to 31 August 2013 where applicable.
A. Compliance with National Environmental Laws
43. The environmental legislation of GOB emphasises reducing the negative impacts of infrastructure development projects and enhancement of the positive impacts. This conforms to the National Environmental Policy 1992 that was enacted based on the Agenda 21 of Rio Conference and subsequent enactments of the Bangladesh Environmental Conservation Act (BECA) 1995 and Bangladesh Environmental Conservation Rules (BECR) 1997. The DOE documents through do not make mention about the provisions for railway tracks and railway bridges specifically. So, the conditions for roadways were followed during preparation of the EMP. The compliance with the national laws is as follows:
Table 5-1 Compliance with National Laws

Subsequently Bangladesh an Environmental renewal of the environmental Environmental Clearance (EC) clearance certificate was Conservation Rules obtained for the years 2010, (BECR) 1997 2012 (2 years) and 2013. Environmental clearance certificate up to Jun 2013 was received on 21 Jun 2012. A further renewal up to Jun 2014 was issued by the DOE on 01 Aug 2013.
B. Compliance with ADB Guidelines
44. According to the environmental guidelines of ADB the project falls under Category B and hence an IEE is sufficient to meet the environmental requirements. An IEE report was prepared by the consultant engaged by the ADB during appraisal. However during the detailed design stage between 2009 and 2011 an updated Environmental Management Plan (EMP) was prepared. The project is also in conformity with the latest Guideline of ADB i.e. Safeguard Policy Statement 2009.
C. Compliance with the Environmental Assessment Review Framework (EARF)
45. An EARF was prepared in 2008 for the original project which involved the implementation of 8 subprojects. Since funding for each subproject would take place at different times, the Multi-tranche Financing Facility (MFF) loan modality was applied. The EARF defines

Bangladesh Railways Environmental Monitoring Report Ministry of Railways 14 #2 Bi-Annual Report - August 2013 BRSIP:Tongi-Bhairab Bazar Double Line Project – Implementation Consulting Services ADB Loan No 2316-BAN, 2845-BAN
the steps to be followed for preparation of environmental safeguard documentation for any of the subprojects, using a step-by-step approach compliant with GOB and ADB regulations and guidelines respectively. It also provides EIA templates and other guidance as well as delineating the role and responsibilities of BR and ADB.
46. According to the requirements of the EARF, the project components selected under Project Financing Request 2 (PFR 2) are being subjected to environmental categorisation and assessment. Three project components proposed under PFR 2 are:
i) Additional financing for double tracking of the Tongi-Bhairab Bazar section; ii) Upgrading of signalling in 11 stations between Irshudi and Darsana; and iii) Rehabilitation of yards and extension of loops at 7 stations from Ishurdi to Darsana and Shirajganj Station.
In accordance with the EARF and ADB, component i), which is the continuation of the investment component under PFR 1 is a category B project and hence had an IEE report and EMP prepared. Component ii) is proposed to be a category C project and hence no further assessment was required. Component iii) is proposed to be a category B project and hence an IEE and its EMP was to be finalised.
47. The EARF also mentions the need for the Reform Project under the MFF to include institutional strengthening and capacity building within BR to address safeguard issues. Accordingly under tranche 1, the delineation of Line of Business (LOB) under BR will address needs for safeguards. Further identification of specific capacity needs and capacity strengthening activities for safeguards will take place in line with other activities under the Reform Project through the course of MFF implementation.
D. Compliance with Framework Financing Agreement (FFA)
48. Schedule 5 of FFA stipulated environmental considerations6. The project’s compliance with contractual environmental safeguards requirements are shown in the Table 5.2.

VI. ENVIRONMENTAL MITIGATION AND MONITORING REQUIREMENTS
A. The Environmental Management Plan
49. The EMP contains 34 mitigation measures and 34 associated monitoring actions, presented in the project work period (preconstruction, construction and operating) they would most likely take place in. Each of the tasks is numbered such that any mitigation measure can be cross referenced to the associated monitoring requirement.
This same numbering is then extended to the EMWS as well as the monitoring checklist, permitting an easy confirmation of the entire EMP implementation procedure (see Appendix5).
50. The potential environmental impacts of the Project and the required mitigation and monitoring measures and the related general timelines are set out in the Environmental Management Plan (see Appendix 4). The detailed implementation schedule is found in the EMWS, a mandatory document of the Contractor, and provided in Appendix 5.
51. The EMP’s mitigation tasks are defined in the EMP’s mitigation table (EMiT) and describe the component of the environment affected, the impact, proposed mitigation action, where it is to take place, when and who will implement and supervise the action.
52. The environmental monitoring requirements are presented in the second part of the EMP, the EMP’s environmental monitoring table (EMoT), also in Appendix 4. This plan considers the scope of monitoring; monitoring parameters; time and frequency; the outputs required and implementing and supervising agencies. This plan also includes a number of specific impacts for which sampling of a range of parameters is required to determine the extent of the impact as a result of the various work activities.
B. Sampling Program
53. The extent of the impacts of environmental pollution related to surface water, ground water, air quality and noise can be determined in quantitative terms by sampling a range of related parameters. Based on these results the mitigation measures provided for in the EMP can be adjusted accordingly. The field sampling work was specified for the construction and operating period.
54. The sampling program is presented in Appendix 6 and is summarised in Table 6.1 below
Table 6.1 Sampling Program Summary
Impact Construction Operating Period Parameter Frequency Dur’n. Frequency During Years
1 Surface Water monthly 3 yrs 2X/yr. 1,3,5 pH, TSS, BOD5, DO, TP, Oil & grease, FC 2 Ground Water 2X/yr 3 yrs 0 Not pH, TSP, As, Fe, Mn, S, Cl, needed FC
3 Air Quality quarterly 3 yrs 2X/yr 1,3,5 TPM, SO2, NO2, CO, Dust & Soot 4 Noise & Vibration quarterly 3 yrs 3X/yr 1,3,5 dBA
55. The sampling follows the methodology provided in the Bangladesh national standard methods for monitoring pollutants. Other associated standards are national environmental quality standards and pollutant emission standards.

VII. ENVIRONMENTAL MITIGATION MEASURES IMPLEMENTED
A. Pre-Construction Stage
56. The implementation status of the mitigation measures to be addressed during the pre- construction stage of the project was presented in the #1 Annual Report to October 2012. These measures have all been addressed effectively and further monitoring and reporting is not required as the Contract is now into the Construction Stage.
B. Construction Stage
57. The implementation status of the mitigation measures during this reporting period are summarised in the Compliance Monitoring Check List provided in Appendix 7. The status of each measure is summarised in the last columns of the tables for comparison with the designed mitigation measures stated in the EMP. Although to date many of the mitigation measures have been implemented there are some significant deficiencies that need to be addressed7 as the number and range construction activities has increased on site.
58. One important area where deficiencies continue to exist and that needs further on-going action is the Health and Safety Issues. Further improvement of the general condition of the camps and work areas in relation to waste disposal, hygiene, medical facilities, etc is still required and general cleanliness and tidiness needs attention. Personal safety including the provision and use of the range of Personal Protective Equipment (PPE) for the workforce is also an area that requires continual attention with frequent and regular training and awareness sessions for all staff.
59. Safety at the many work sites with the provision of signs and notices, warning flags, safety barriers and fences, shoring of excavations and general safe working practices is also an area that requires continual attention with regular maintenance and frequent replacement of many of the precautionary devices used.
60. The extent of the impacts on surface and ground water, air quality, noise and vibration from the various work activities has not been determined as the sampling program, defined for the Contractor at workshops, meetings and through personal communications has not been carried out correctly. Therefore the data that has been obtained is of limited use. There has however been a marked improvement in this area since May 2013 and further improvement to achieve full compliance has been committed to by the Contractor. These activities are discussed in detail in the following section on the Sampling Program.
C. Sampling Program Results and Analysis.
1. Surface Water (EMP 2.5.1)
a. Results of Sampling
61. Sampling is required monthly at 4 main rivers and one dredging site (10 samples/month) with a set of samples to be taken at each location upstream and downstream of the work site.
62. In the absence of applicable Bangladesh standards for aquatic life the reference standard of Canadian Water Quality Guidelines for the Protection of Aquatic Organisms (2003) has been applied. In particular the limit of faecal coliform for aquatic harvesting where applicable has been referenced. The data presented was collected while active pile placement
7 CSC has formally notified CREC of these deficiencies by letter and during regular meetings

b. Summary and Assessment
63. With the data now available it is possible to draw initial conclusions regarding the effects of the project activities on the water quality as summarised in the following table

64. Since the samples from upstream and downstream of the worksites indicated very similar results, in some cases higher values upstream of the work sites, project impact would appear to be marginal.
65. Of considerable significance is the large variation in DO levels between the April-end of dry season and low flow period and the July-August rainy season. The data suggests that all four rivers are anoxic during part of the year, making them unfit as fish habitat, at least for part of the year. The generally high nutrient loading (TP) and BOD5 levels support these findings. Background faecal coliform levels are dangerously high making any fish caught from these waters and not cleared in clean water for 5-7 days, unfit for human consumption. Drying does not clear the bacteria. As well the high grease and oil levels in these waters impact the quality of any fish taken from the rivers, tainting the flavorand significantly decreasing their salability
66. In the case of pH, total suspended solids, biological oxygen demand, and dissolved oxygen the majority of the levels are within the acceptable limits, with upstream and downstream readings varying little suggesting no significant impact by the project. In the case of phosphates the recorded levels are just above the limit during the dry season, but below the limit in August indicating the affects of the increased river flow during the wet season. There is also little deviation up and down stream. The levels for Oil and Grease and Faecal Coliform however are well in excess of the limits both up and downstream of the worksites and show large variations suggesting large periodic industrial discharges of pollutants upstream of the sampling sites, not attributable to project activities.
67. Although there is no reliable baseline data the upstream and downstream results suggest that there is minimal impact of the project activities on the surface water quality of these water courses.
2. Ground Water (EMP 2.5.2)
a. Results of Sampling
68. Sampling is required every 6 months at new wells bored for camp water supplies and at existing tube wells within 150 metres of pile boring (5 samples/6 months). However sampling and testing of ground water quality have not been carried as specified out until recently. Starting in August 2013 two samples were tested at each of five tubewells near the major construction sites.

b. Assessment
69. With the absence of baseline data it is difficult to draw any logical conclusion from the new results. CREC was alerted to this issue already in June 2012. However with the majority of parameters in excess of the GOB drinking water standards the need to provide alternative sources of drinking water is essential. This has been addressed by the use of bottled water as drinking water at project site offices and some camps with local staff using drinking water from nearby houses.
70. The Contractor has also taken note of the high arsenic levels in the water at the Br#34 camp and has prohibited all staff from using it as drinking water and is providing alternative potable water sources.

71. The high TSP level would also suggest that the tubewell water has been contaminated from a surface water source. Continued testing will hopefully help in defining the source of these high particulate matter levels. Often, poorly dug and sealed tubewells, result in chronic leakage of contaminated surface water back into the well. The contractor has been alerted to inspect all tubewell sites to insure that they are sealed and that no contaminated water enters the system. Secondly the contractor has been instructed to erect signs at each tubewell instructing users not to wash, brush teeth or otherwise use the water within 10m of the tubewell site-where water remains fit for human consumption.
3. Air Quality (EMP 2.5.3)
a) Results of sampling
72. Sampling is required quarterly (every 3 months) at 4 main bridge construction sites, one crushing plant site, 2 active works sites and 3 stations (10 samples/quarter). One sample within 50m of active works site and one sample at closest boundary to the community. Sampling and testing of air quality have not been regularly carried out to date as specified although the Contractor indicated in his April 2012 report that he had suitable equipment available for this testing. Limited sampling and testing was done in June 2013 with further sampling and testing to be carried out in the coming months in line with the Sampling Program.

b. Assessment
73. The data presented in this table indicates that the results for the specified parameters are well below the GOB standards and where records are available are less than the baseline recordings suggesting that the project activities are having minimal impact on air quality. Given the extremely small sample size, these results should be viewed as preliminary findings. The complete survey analysis being undertaken in September 2013 should provide a much more robust dataset.
4. Noise
a) Results of Sampling 74. Sampling is required quarterly (every 3 months) at 2 major bridge construction sites (#79, #89), one crushing and one batching plant site, one ballast dumping/laying site, one dredging site and one Class B station (7 sample sets/quarter). Samples are to be taken at the nearest occupied structure to the works (A) and the next closest receptor (B), with & without a train passing, once during peak working time and once at night.
75. For the 14 month period from the first recordings in April 2012 until May 2012 sampling was carried out for four months at the sites indicated in Table 7.5. During the period there was no construction activity at any of these sites with the exception of the Pubail Station until January 2013, therefore they represent background conditions. The data shows that in relation to standards for mixed commercial, industrial and residential land-use, noise levels are already exceeded during the day and at night. However, there is also no indication whether any of the samples include train movements at these locations.

b) Assessment
77. The data presented suggests that the ambient noise levels at these locations exceed the maximum limits specified by the GOB.
78. It is also observed that the single measurement showing the effect of passing trains shows a >20 dBA rise in noise while a train is passing. This effect will be checked as further data becomes available in the coming months. It is likely that residences within 50m of the rail line will require noise attenuation measures to be identified as the future noise measurements become available.
5. Fisheries Resource.
79. Of the many smaller waterways crossed by bridges or passing under the existing railroad in culverts, there are four significant rivers, in terms of flow and width, crossed by railroad bridges. These are the Old Brahamaputra, Arial Khan and Sitalakha Rivers with the, Balu waterway being the smallest.
a) Old Brahamaputra River
80. The Old Brahamaputra River at the bridge crossing (No. 34) is well over 200m wide and has an average annual flow of 1,270m3/sec.. It is between 5 and 12 m deep and the new bridge
Bangladesh Railways Environmental Monitoring Report Ministry of Railways 26 #2 Bi-Annual Report - August 2013 BRSIP:Tongi-Bhairab Bazar Double Line Project – Implementation Consulting Services ADB Loan No 2316-BAN, 2845-BAN
has 5 new equally spaced piers in the water, each measuring 1.75 m in width. Therefore the width of the river taken up by the new pier is approximately 9 m or 4.5% of the total width. The world literature on fish movement and obstructions in rivers indicates that a blockage of ≥30% of the river width could impact fish movement.
81. Common species of catfish (Rui, Catla, Mrigal, Ghania, Kalbasu, Kalia) and carp (Rita, Boal, Pangas, Silon, Aor, Bacha), as well as several species of snakehead fish are likely found in this tributary of the Padma River and do not migrate for the most part. They live in local territories and move into shallow wetland areas to spawn. With only about 4.5 % obstruction of the river width the impact on Bramahputra fish is far less than the chronic discharge of oily, toxic and bacterial laden wastes, killing the fish or tainting their flesh. This is the only project activity affecting the fish and is not considered a serious concern. The Old Brahamaputra actually empties into the Arial Khan just before the water reaches the Padma.
b) Arial Khan River
82. The Arial Khan River, where the rail line now crosses it (Bridge No. 63), is about 170- 180m wide and has an average annual flow of 2030m3 /sec. Four new bridge piers are in the water, each around 1.5 m in width, occupying a total distance of 6 m, equivalent to around 3.4% of the river width. The removal of 3.4 % of the width is far less than the average annual dry-wet season variations as well as the daily tidal fluctuations which can be around 0.31m reducing the river width by more than 15%. The water quality data suggest conditions similar to the Old Brahamaputra river, namely near anoxic during the dry season, due to massive organic matter and chemical loadings. The Arial Khan empties into Padma through at least six secondary natural canals or khals, providing many options to fish movement . 83. Species found in the river are likely close to the diversity found in the Old Brahamaputra, and possibly more diverse, due its very low topography and abundant wetland conditions. Seasonal wetlands are critical habitat for small food-fish species vital to the rural diets, and should be minimally impacted by the project since closely spaced culverts are being installed to insure wetland maintenance. However, the contractor is being instructed to monitor this situation very carefully, and report wetland drying or flooding.
c) Sitalakha River
84. The Sitalakha River is the largest to be crossed by the project, at 330m. It has an average annual flow of 1,470m3/sec. Ten new piers have been placed into the river, each around 1.7m in width, occupying around 17m of the river cross-section. This equals around 5.3% of the river width at the crossing site, and is of no concern regarding a potential block to fish movement.
85. For at least 20 km upstream from where the Balu River emptiesinto the Sitalakha, the water quality is that of an industrial discharge canal (Md. Akramul Alam, A.B.M. Badruzzaman and M. Ashraf Ali. 20128). There are several different types of industries like textiles and dyeing, paper and pulp, jute, pharmaceuticals, fertilizers, all discharging untreated wastes into the river. There are also moderate to big urban developments along the entire stretch of the river, all without sewage treatment facilities.
86. The river where the rail line passes over it is not fit for fish life. At the downstream end where it and the Balu river join is a virtual open sewer, with a massive pollution load from the Balu joining the Sitalakha effectively blocking any fish movement upstream.
8AkramulAlam et al. 2012. Spatiotemporal Assessment of Water Quality of the Sitalakhya River, Bangladesh. International Journal of Engineering and Technology:2 ( 6) pg 953-962
Bangladesh Railways Environmental Monitoring Report Ministry of Railways 27 #2 Bi-Annual Report - August 2013 BRSIP:Tongi-Bhairab Bazar Double Line Project – Implementation Consulting Services ADB Loan No 2316-BAN, 2845-BAN
87. An indication ofit level of contamination is that even during the rainy season with high water flows the DO levels remain less than 6 mg/L and drops to 0.53mg/l during the dry season. BOD5 levels which for moderately polluted waters are around 2mg/L are two to three times that at the river crossing which is quite far upstream from the major industrial discharges.
88. To conclude, and given the scale of existing contamination and habitat loss in this river, there is literally no chance that the bridge crossing work , which has been undertaken according to the EMP mitigative measures, could impact the fish and fisheries. The first priority should be the reduction of untreated industrial and sewage waste into the river.
d) Balu River
89. The Balu River, is 60m wide at the point where the bridge has been placed. Since there are no piers in the water and no activity on the water this work has no fish and fisheries implications.
e) General Assessment
90. There is no doubt that fish populations, their habitat and water quality in general are all seriously threatened by industrial chemical and sewage discharges, the dewatering of essential wetlands home to many of the small food fish essential in rural Bangladesh diets, and unregulated fishing. Well over 100 of Bangladesh’s wetland and river fishes are vulnerable, some threatened with extinction, all due to land use changes and chemical pollution.
91. Construction of a second rail line within an existing corridor has virtually no impact when compared with the ongoing degradation of rivers and wetlands through various types of uncontrolled pollution.
93. During the field surveys, both the Arial Khan and Sitalakha Rivers were seen running purple, green and black from upstream industrial discharges. Regardless, water quality will continue to be monitored and fish surveys will be conducted to establish the species present and the quality of the catch.
6. Wildlife
94. The impact of the second set of tracks within the rail ROW is not expected to displace wildlife given that the area disturbed is largely plantation and second growth trees and scrub.
95. Bird species such as terns, kingfishers, kites and sandpipers have been observed along the corridor at the river crossings, but none other than sparrows, swallows, raven and mynahs along the tracks. Occasionally varies species of common kite found along wetland areas were observed. The Brahmaputra and Arial Khan wetland along the rail line have additional aquatic birds, most common being the cattle egret and coot. None of these habitats will significantly be impacted by the work, since only very small narrow stretch within the RoW will be used to establish the new embankment.
96. Within the RoW and the areas where embankment is to be placed is all either paddy, pasture or water ditches paralleling the tracks. Some of these ditches may be home to common amphibians and reptiles, non-endangered by this project. During the many field inspection and during the more than 1.5 years of work, no wild mammals have been reported or seen either dead or alive in the project corridor.

7. Overall Assessment of Sampling Program
97. Prior to April 2013 the Contractor was not complying with any of the sampling requirements. Since that time the Contractor has increased sampling activities significantly with further improvements committed to for the forthcoming months and some indication of the project affects can be inferred. CREC has been regularly reminded of the issues with the sampling program and for each monthly report submission and has received feedback concerning data collection.
98. For all the sampled parameters the results suggest that in many cases the ambient levels for water, air and noise are already near or in excess of the national and international standards. Future more credible and precise sampling will help identify if the project is having any measureable impacts on the environment.
D. Compliance Status Reporting
99. Overall compliance status with key actions defined in the EMP, as indicated in the Compliance Monitoring Check List in Appendix 7 is summarised in Table 7.6

With the improvement in the sampling activities to be carried out in the forthcoming months in line with the sampling program it is likely that the fully compliant status could be well in excess of the 70% shown in Table 7.6 for August 2013. . The Contractor has been advised that partial compliance in key areas such as waste management and discharge of pollutants in not acceptable and that immediate action is needed.

103. The chart shows a decline in compliance during 2012, as construction activities increased triggering mitigative measures that the Contractor did not act on. The intensive actions by the CSC and assistance given the Contractor is now paying off, as the compliance status has risen steadily with no applicable clauses remaining non-compliant on August 31st, 2013.
104. The number of clauses where the contractor remains marginally compliant is too high and further reminders have delivered. CSC is optimistic that significant improvements will be recorded for the next reporting period, particularly as the Contractor retained a Bangladesh environmental specialist in May 2013 to carry out the environmental safeguard mitigation and monitoring program.

IIX. KEY ENVIRONMENTAL ISSUES AND ACTION PLAN
A. Key Issues Identified
105. Based on the results of monitoring and inspection as presented, there are no significant environmental issues raised during the reporting period. However there are a number of areas where more action needs to be taken by the Contractor to ensure full compliance with the EMP as many more activities will commence on site.
B. Action Plan of Environmental Mitigation and Monitoring in between August 2013 and December 2013.
106. It is expected that further substantial increase in construction activities will occur from September 2013 when many of the work sites will become accessible after the wet season. The focus of environmental monitoring will be on the following aspects: (a) better implementation of environmental management plan and mitigation measures to minimize the negative environmental impact of the work under construction; (b) Continue to improve water, air and noise quality sampling and analysis of the project by adhering to specific instructions provided by the CSC. Pay close attention to the causes of non-compliance and remediation measures to secure safe water supply, air quality and acoustic environment; (c) Ensure soil erosion protection of the embankment and the bridge sites; and (d) Strengthen the implementation of the Health and Safety aspects of the EMP for the entire workforce.CSC intends to strictly enforce these requirements and with the help of BR be able to demonstrate a substantial improvement by the Contractor over the remaining months of 2013.
107. Of these the Health and Safety issues will need continued and on-going attention with all of the site activities including track laying and signaling works in progress where the safety of works adjacent to the operating line will be paramount, both for worker’s safety and for the safe operations of the train services. The action plan is defined in Table 8.1, and will be expanded by the contractor.
108. The CSC considers the earlier submissions by the Contractor to be substandard and as a result an environmentally acceptable assessment of impacts has been difficult. However the CSC is encouraged by the renewed commitment of the Contractor and his staff who are working closely with the CSC to make significant improvements.

IX. CONCLUSION
A. Overall Progress of Implementation of Environmental Safeguard Measures
110. Based on the monitoring by the CSC of the environmental activities on the TBDLP it is found that the contractor, CREC has begun to undertake many of the environmental mitigation measures specified in the EMP although there are many areas where further action and improvement need to be provided. The conclusions of the environmental monitoring are summarised as follows.
111. The potential adverse impact of the finished works on the major watercourses and overall drainage of the area have been minimized by ensuring the design and construction of the new embankment and structures generally match the embankment and structures of the existing track alignment. The potential adverse impact of dust from the transport of large quantities of embankment materials has been minimized by use of dredged sand delivered by pipelines to the worksites with borrow generally obtained with the ROW locally to avoid large haul distances9.
112. Further improvement is still needed to execute the monitoring of water and air quality, noise levels and soil contamination fully in line with the Sampling Program so that the impacts on these of the construction activities can be quantified and thereafter minimized wherever possible.
113. Further emphasis is also required on the Health and Safety issues related to the various camp sites and work sites with more training and awareness sessions needed regarding the use of personal protective equipment (PPE) for the workforce. The Operational Safety aspects of working adjacent to the existing open line must also be highlighted with training and awareness sessions being held on a regular basis against an agreed program with improved presentation and delivery by specialised personnel.
B. Problems Identified and Actions Recommended.
114. Based on the site surveys and monitoring of the execution of the Environmental Safeguards program the relevant recommendations are included below.
9.1 Recommendations
