Construction of Single Line Dual Gauge Railway Track from Dohazari to Cox’s Bazar via Ramu and Ramu to Gundum Near Myanmar
EXECUTIVE SUMMARY
1. Bangladesh Railway has taken numbers of initiative to improve railway connectivity among the South Asian and other Asian countries with Bangladesh. The project for which this semi- annual report has prepared is entitled as “Construction of Single Line Dual Gauge (DG) Railway Track from Dohazari to Cox’s Bazar via Ramu and Ramu to Gundum near Myanmar”. 2. Monitoring works mainly focused on inspection of construction activities during construction period as per approved EMP & EIA for this project. A monitoring checklist has submitted by the Contractor which is already approved by the Engineer and has used in the field level to monitor environmental safeguards. This Semi-annual EMR has gathered all the information, summarized all results and evaluated the overall environmental safeguard status from 1st July of 2018 to 31st December of 2018 for DCRP. 3. Considering the full compliance (C) issues over the reporting period, it is found that significant numbers of checklist items were complied with the standard level or EMP. As the project was at initial stage, most of the issues were found as not applicable (NA) for the specific sites. Beside this, since the commencement of the DCRP, HSE team of CREC-TOMA JV (CTJV) and CCECC-MAX JV (CMJV) has been working proficiently in order to comply with contract agreement, EMP of the EIA and eventually save every sector of environment from the construction effects. 4. During the reporting period, HSE team of CTJV & CMJV has submitted HSE Plan, Traffic Management Plan, Hill Cutting Management Plan and Waste Management Plan to the Engineer for approval. After reviewing the submitted plans, Engineer will approve based on which Contractor will implement environmental safeguards at construction site. According to the Subsection H: Environment Safeguard, a noise decibel meter and calibration tool will be used in the field level for recording spot noise readings as required. Accordingly, HSE team of CMJV has submitted an official letter to the Engineer for their review and approval where it enclosed necessary information such as Noise Meter Model with detailed specification. Consequently, the approval is being done from the Engineer’s side. 5. An environmental expert’s team from the Contractor’s side has conducted 2nd and 3rd Quarter Environmental Sampling from 18th September to 25th September and 19th December to 26th December 2018 respectively to monitor Air Quality, Noise, Surface Water & Groundwater Quality at different sites using sophisticated instrument. The 2nd & 3rd Quarter Environmental Sampling data has attached in this report. As a result, a comparison made between June (baseline survey), September 2018 and December 2018 quarterly findings. 6. Consultant’s environmental team along with the HSE team of CTJV & CMJV has been working on environmental, health and safety issues raised in the field level during regular visits at all construction sites. The team has taken mitigative and monitoring measures when required through physical activity, maintaining records and through reporting of different potential environmental impacts associated with construction activities.

7. During the site inspection generated noise pollution, dust pollution, disposal of construction waste, maintenance of equipment, pollution & contamination such as leaks & spillage of oils, hill cutting and occupational health & safety arrangement have monitored as a key environmental issue for the reporting period. 8. Overall based on the construction activity and its associated impact, it can likely be concluded that, the project has less significant impact to the environment till now. No major environmental impacts due to project activities have been identified or recorded, therefore, complied with the EMP as well as contract. 9. Furthermore, it is prime duty of all to cooperate to ensure both work place safety and carried out the construction work in an environmentally acceptable manner for the DCRP. Furthermore, to ensure the monitoring and reporting are completed in a compliant and timely fashion, acceptable to BR and ADB.

INTRODUCTION
A. Purpose of the Report 10. The Construction of Single Line Dual Gauge Railway Track from Dohazari to Cox’s Bazar via Ramu (about 100.8 Km) was classified as Category Red by the Department of Environment (DoE) and a Category A project by the Asian Development Bank (ADB), thus the EMP of the EIA report designates best applicable available mitigative measures to be taken either to avert negative impacts from taking place or if that is not possible to mitigate them to an acceptable limit. 11. The purpose of this Semi-annual EMR is to gather all the information, summarize all results and evaluate the overall environmental safeguard status from 1st July of 2018 to 31st December of 2018 for DCRP (Lot 1 & Lot 2). Accordingly, this report will reflect the Contractor’s professional effort to comply with contract agreement, EMP of the EIA and eventually save every sector of environment from the construction effects.
B. Project Description 12. The project area covers from Dohazari Upazila of Chittagong District to Cox’s Bazar Sadar Upazila of Cox’s Bazar District via Ramu and it covers Chandanaish, Satkania, and Lohagara Upazilas of Chittagong District; Chakaria, Cox's Bazar Sadar and Ramu Upazilas of Cox’s Bazar District. In addition, nine new rail stations and access roads have been designed for this project (Figure 1). 13. The proposed alignment will cross mainly crop land (59.67%), highland/hilly land (24.78%), orchard/ forest land (8.98%), homestead land (5.58%), and others (0.99%). The areas designated as reserve forest is owned mainly by the Bangladesh Forest Department (BFD). The first 29 km from Dohazari onward consist of flat-open land located in three Upazilas of Chittagong District. The next 33 km fall within the Chakaria Upazila of Cox’s Bazar District and traverse agricultural farmland and some forest land. For the next 33 km, within the Cox's Bazar Sadar and Ramu Upazilas of Cox’s Bazar District, the alignment climbs to about 400 m above sea level and passes through mostly tropical jungle and rural agricultural land.

24. Figure 3 represents the overall status of the environmental safeguards monitoring over six months for Lot 1. It is evident that first three months of this year there was no major activities take place therefore; no issues have been recorded throughout this period. Afterwards, some noticeable activities were started gradually, for instance site preparation, earthwork and construction of Bridge No. 3 and nearby batching plant. From Figure 3, it is evident that record amount (5 out of 67) of non-compliance (NC) issues are found in the month of September in the field level at different sites as because of very initial moment of work and lack of proper 25. management and resource unavailability. However, the condition has been improving overtime and NC issues reduced from 5 to 3 in the end of December.On the other hand, partially compliance (PC) issues are found in highest quantity for instance, 24, 25, 29 and 31 out of 67 environmental monitoring items for the month of September, October, November and December respectively.

Figure 3: Schematic representation of environmental safeguards monitoring status for Lot 1
26. Considering the full compliance (C) issues, over three months, it is found that significant number of checklist items for instance 19 in September, 22 in October, 20 in November and 22 in December, are complied with the standard level or EMP or found in good condition. Finally, there are some issues recorded, where the requirements do not apply at the Project current time which indicated as not applicable NA. And the NA amount was high in number during the commencement of the work. It can be concluded that, based on the statistics of major four months activities, the overall progress of environmental monitoring of this DCRP is good enough (PC) and have huge chances to improve noticeably NC and PC items in the coming months. 27. Figure 4 represents the overall status of the environmental safeguards monitoring over six months period (i.e. July to December 2018) for Lot 2. It is evident that the first three months of the second half of this year there was no major activities take place but started the pilot pile work at different places i.e. Camp construction and Bridge construction at BR 124, BR 96, and BR 130. 28. Besides, during this first three month it was rainy as well, therefore, no significant earthwork was performed. Additionally, sometimes it was hard to maintain proper housekeeping due to torrential rain. Afterwards, some noticeable activities were started gradually, for construction of pilot pile and working pile at 9 different bridge locations, earthworks (i.e. clearing, grubbing and stripping, installation PVD, Placement of Granular Sand Drainage Layer, installation of Geo textile, back filling, embankment filling, establishment of Ramu Lab and Ramu Yard.
14
Construction of Single Line Dual Gauge Railway Track from Dohazari to Cox’s Bazar via Ramu and Ramu to Gundum Near Myanmar
29. Since, there were so many constructions at various places, therefore, it was hard to control eventually found some non-compliance issues. From the Figure 1, it is evident that record amount (12 out of 67) of non-compliance (NC) issues are found in the month of July in the field level at different sites as because of very initial moment of bridge construction works, lack of proper management and torrential rain. 30. However, the condition has been improved overtime and NC issues reduced from 12 to 0 in the end of December. Some partially compliance issues were recorded during this six month period such as in July there were 15 partially comply issues recorded. Likewise in August there were 22, September- 19, October- 16, November-10 and in December there were only 8. On the other hand, a record amount of compliance issues were found during the last six months period. Considering the full compliance (C) issues, during the last quarter, it is found that significant number of checklist items for instance 40 in October, 45 in November and 48 in December, are complied with the standard level or EMP or found in good condition. 31. Finally, there are some issues recorded, where the requirements do not apply at the Project current time which indicated as not applicable NA, for instance, human elephant conflict, and hill cutting. Apparently, these kinds of works not started yet due to land acquisition problem. Finally, it can be concluded that, based on the statistics of major last three months activities, the overall progress of environmental monitoring of this DCRP Lot 2 is good enough and put the level in between partially compliance an compliance. 32. However, there are lot of chances to improve noticeably NC and PC items in the coming months. HSE team of CT JV & CMJV has been working on new issues raised in the field and trying to overcome the worse situation.

SUMMARY OF ENVIRONMENTAL MONITORING
A. Construction Period Environmental Quality Assessment 33. In order to ensure proper implementation of the environmental safeguard requirements during the construction period, the Contractor has appointed Bangladesh Railway approved organization named Environmental and Resource Analysis Center (ENRAC) Ltd., to conduct air quality testing, noise measurements, surface water quality testing, and groundwater quality monitoring and recording on a quarterly basis. The organization has necessary technical resources and work experience to conduct this work credibly. All instrument used by the organization are maintained International Standard and calibrated in accordance with the manufacturer’s instructions. 34. ENRAC has conducted a baseline survey in the field level (26th to 30th of June 2018 at Lot 2 only), second quarterly survey from 18th to 25th September 2018 and the 3rd one between 19th to 26th December 2018 to measure Air, Noise, Surface Water and Ground Water quality at different sites using sophisticated instrument for accurate measurement. A comparison was made based on 2nd and 3rd sampling findings in the report. 35. According to the Clauses H 4.2 to H 4.5, Environmental safeguard implementation program is described in the following:
1) Air Quality 36. During every quarterly survey, air sampling was undertaken at 8 sample stations 2 samples per station, making a total of 16 samples. The objective of this air sampling at 8 different stations under DCRP Lot 1 & 2, is to verify air quality on a quarterly basis in order to make comparisons between pre-development and post-development, detect change, and make
comparisons against a standard. The measured parameters are such as CO, SO2, NO2, PM10,
PM2.5, & Air Temp (°C). The parameters were measured in the field using a real-time sampling device, the Environmental Parameter Air Sampler or EPAS (HAZ-SCANNER, model-HIMM- 6000) built by the Environmental Devices Corporation (EDC), USA. The ambient air quality monitoring was performed in presence of Consultant representatives. i) Ambient Air Quality Monitoring Frequency, and Locations 37. Table 6 shows the three quarters sampling locations of the DCRP.

ii) Ambient Air Quality Monitoring Methodology 38. Accordingly, to comply with both the EIA and EMP, the team has taken two samples from each station, the first at the closest sensitive receptors such as settlement areas less than 50m from the track, and the second at around 100 m distance from the centerline of the proposed alignment with maintaining 4hrs time period of continuous monitoring. The parameters were measured in the field using a real-time sampling device. Measurements were recorded continuously using a battery-operated instrument, sampling once every five minutes over a one-hour sample period (the sample time interval is selectable on the EPAS data logger). iii) Analysis of ambient air quality measurement Lot 1 39. The following Table 7 and Table 8 represent the ambient air quality measurements for four different stations during baseline environmental monitoring and second quarterly environmental monitoring respectively.

44. From the Table 9, it can be concluded that CO and SO2 concentration is showing a decreasing
trend whereas the NO2 concentration is showing an increasing trend from baseline to second
quarterly environmental monitoring. The PM2.5 and PM10 does not show any trend in concentration, that it means those parameter concentrations vary from one sampling station to the other. However, such comparisons can be made only for AQ_1, AQ_3 and AQ_4 as samples were taken from AQ_2 only during baseline monitoring while samples were taken from AQ_5 only during second quarterly monitoring. v) Analysis of ambient air quality measurement Lot 2 45. Analysis of ambient air quality measurement (September, 2018): It is evident from the Table 10 that the Carbon Monoxide concentration ranges from 0.02 to 0.61 µg/m3. The concentration of the samples was found within the DoE air quality standards. Additionally, breathing CO can cause headache, dizziness, vomiting, and nausea which is not recorded at any of our construction sites after having few conversations with workers. Overall due to any construction activities the concentration of CO in our selected stations is not increasing.
46. Ambient SO2 concentrations (which is released from the fossil fuel combustion) in all sampling locations showed compliance with the specified air quality standards for BD which

2) Noise Quality 52. During every quarterly survey, noise sampling was undertaken at 8 sample stations; 2 samples per station, making a total of 16 samples. The objective of this noise sampling at 8 different stations under DCRP Lot 1 & 2, is to verify noise quality on a quarterly basis in order to make comparisons between pre-development and post-development, detect change, and
make comparisons against a standard. The filed level noise was measured in (Leq) dBA using Lutron SL 4033SD Sound Level Meter (Photo 21 & 24). i) Noise Quality Monitoring Frequency, and Locations 53. Table 13 shows the three quarters sampling locations of the DCRP Lot 1 & 2.

ii) Noise Quality Monitoring Methodology 54. The environment team from the CTJV & CMJV has finished data collection from the field to measure required noise quality parameters from the pre-specified (Table 13) locations. Noticeably, the team followed both the EIA and EMP guidelines, therefore, two measurements per station, in two time periods, 1 sample during the day time (after 9.0 am) considerably 100m away from the source point while using a one-hour cycle recording values every minute and 1 sample after 9.00 pm 100m away from the source point using one measurement for 15 minutes with a one-minute interval. Likewise, a total of 16 samples were collected from 8 different sampling stations using Lutron SL 4033SD Sound Level Meter in presence of Consultant representative. iii) Analysis of noise quality measurement of Lot 1 55. Other than the noise from adjacent roads, there are no major noise pollution sources in the Project area. The noise level measurements of four sampling stations, in the day and night from 22nd to 25th September, 2018 during baseline environmental monitoring and 19th to 22nd December 2018 during second quarterly environmental monitoring, are shown in Table 14 and Table 15 respectively. 56. Of the five sampling stations, two stations were very near to the main road. For instance, Chakaria & Dohazari Stations which can be considered as mixed area since there is neither any big industry nor large scale commercial activities take place rather residential area; green fields can be seen very often. On the other hand, Lohagara and Harbang station is situated a bit far from the city crowds within the middle of the remote agricultural land. Consequently, this station can be put in the category of both residential and mixed zone. Bridge No. 15 is the newly added sampling station replacing Lohagara Station during second quarterly environmental monitoring located in a rural setting surrounded by residential houses.

57. The existing general average noise level within the study area varies from 33.9 dBA to 49.1 dBA found near to the batching plant of Chakaria station premises during night time and near the batching plant of Dohazari station area during the daytime respectively. During the second quarterly environmental monitoring, average noise level within the study area varies from 39.39 dBA to 57dBA found near to the batching plant of Chakaria station premises during both day and night time. 58. Noticeably, these recorded values are within the standard of mixed zone land use (DoE, 1997), as well as for the commercial zone, which is the designation for the railway corridor. Being a commercial area, the ambient standard is 70 dBA (day) and 60 dBA (night) (DoE, 2006). All the noise records of both day time and night time data meet the desired standard for mixed zone, residential and commercial area. Overall, the noise measurements were found moderate as all the sampling sites were located in semi-rural to rural setting.

The Table 16 shows comparison of noise level status between the baseline environmental monitoring and second quarterly environmental monitoring. From the Table 16, it can be concluded that the average noise levels, both during day and night time showing an increasing trend from baseline to second quarterly environmental monitoring except for NM_1 during daytime. However, such comparisons can be made only for NM_1, NM_3 and NM_4 as samples were taken from NM_2 only during baseline monitoring while samples were taken from NM_5 only during second quarterly monitoring.

Analysis of noise quality measurement (September 2018) of Lot 2: The noise level measurements in the day and night from 18th to 21st September 2018 shown in Table 17. The data were collected from four different sampling stations. Of the four sampling stations, two stations, are very near to the Cox’s Bazar Chattogram high way, for instance, Cox’s Bazar, Max Yard/Ramu Yard which can be considered as mixed area since there is neither any big industry nor large scale commercial activities take place rather residential area, green fields can be seen very often. On the other hand, the remaining Rubber dam and Napith Khali camp
27
Construction of Single Line Dual Gauge Railway Track from Dohazari to Cox’s Bazar via Ramu and Ramu to Gundum Near Myanmar
station is situated a bit far from the city crowds within the middle of the remote agricultural land. 61. Consequently, this station can be put in the category of both residential and mixed zone. The existing general average noise level within the study area varies from 63.17 dBA to 69.41 dBA found near to the Rubber dam area during night time and daytime respectively. Noticeably, these recorded values are slightly above the standard of both mixed and commercial zone land use (DoE, 1997). Being a mixed area, the ambient standard is Leq 60 dBA (daytime), and Leq 55 dBA (night time), and for the commercial area it is 70 dBA (day) and 60 dBA (night) (DoE, 2006). Most of the noise records during the day time data exceed the desired standard for mixed zone that varies from 58.68 to 69.41 dBA, however, on the other hand night measurements meet the minimum standard (ranges from 47.38 dBA to 63.17 dBA) but one that recorded at the rubber dam area which was 63.17 dBA because of rain drops sound. As the day and night time noise monitoring for each location has conducted parallelly (same location at same date). To maintain this, the night time measurement of noise at rubber Dam Area has conducted at the time of rainfall. Overall, the noise measurements were higher than what one would expect in a totally rural setting.

measurements in the day and night from 23rd to 26th of December 2018 shown in Table 18. The data were collected from four different sampling stations (See Table 13) of the DCRP of Lot 2 as selected by the Engineers. Of the four sampling stations, two stations, are very near to the Cox’s Bazar Chattogram high way, for instance, Cox’s Bazar, Ramu Yard which can be considered as mixed area since there is neither any big industry nor large scale commercial activities take place rather residential area, green fields can be seen very often. 63. On the other hand, the remaining Rubber dam and Islamabad station is situated a bit far from the city crowds within the middle of the remote agricultural land. Consequently, this station can be put in the category of both residential and mixed zone. The existing general average noise level within the study area varies from 51.7 dBA to 48.8 dBA in Rubber dam area during day time and night time respectively which is under the standard of both mixed and commercial zone land use (DoE, 1997). Being a mixed area, the ambient standard is Leq 60 dBA (daytime), and Leq 55 dBA (night time), and for the commercial area it is 70 dBA (day) and 60 dBA (night) (DoE, 2006). Overall, the noise measurements during this quarter were found within the acceptable level.

A comparison is made based on quarterly reports i.e. June, September and December 2018. Table 19 shows that September data found slightly over the permissible standard (Day- 69.41 & Night- 63.17 dBA) at BR 124. Noticeably, at that time many construction activities were on going therefore, exceeds the limit. Overall the noise quality under DCRP Lot 2 is under control and have no such negative impact identified on the workers. Additionally, noise barricading is provided as per controlling excessive noise near generator and workers usually don’t work nearby noise source for long time. Therefore, there is no objection recorded from the workers as well as from the local regarding the noise pollution at the construction sites.

The objective of this surface water sampling at 4 different stations under DCRP Lot 1 & 2, is to verify water quality on a quarterly basis in order to make comparisons between pre-development and post-development, detect change, and make comparisons against a standard. The measured parameters are
such as pH, Turbidity, Temperature, DO, BOD5, COD, TSS, TDS, Oil and grease. The collected sample water was tested at reputed scientific laboratory in Bangladesh i.e. DPHE & BCSIR. The surface water quality monitoring was performed for the DCRP in presence of Consultant representative. i) Surface Water Quality Monitoring Frequency and Locations 66. Table 20 shows the three quarters sampling locations of the DCRP.

ii) Surface Water Quality Monitoring Methodology 67. According to the Clause 2.4.1 of the EMP, samples were collected at four proposed bridge crossing sites: two water samples per bridge: one 25m upstream and 25m downstream from the planned bridge alignment. Prior starting the sampling procedure, the team dressed appropriate PPEs. However, due to shallow water level of the source, sometimes it was not possible to maintain 1.5m depth. The collected water samples were poured into 1 plastic and 2 amber bottles (for E. coli and Oil & grease), then put some marking to identify them later before analysis and stored according to standard methods and analyzed within 24 hours of being collected at an ISO14000-certified laboratory. iii) Analysis of Surface water quality measurement Lot 1 68. Rivers, canals, and ponds water quality within the proposed alignment of the DCRP is one of the key concerns as they are used for drinking and domestic purpose, irrigation and aquatic life including fish and fisheries. Thus, it was a requisite to test surface water quality of the project area. Accordingly, four sampling stations were identified using GPS coordinates, with one station upstream and one downstream of the crossing area, for a total of 8 sampling points along the proposed alignment. 69. After collecting surface water quality samples, they were sent to the laboratory for testing the necessary parameters including Temperature, Turbidity, pH, TDS,TSS, Fe, DO, COD, BOD, Total P, Oil, and Grease. Department of Public Health Engineering (DPHE) and Bangladesh Council of Scientific and Industrial Research (BCSIR), Dhaka are the organization that tested the required parameters from the submitted samples and provided test reports enclosing in their official letter heading. Results of the water tests are shown in Table 26 and Table 27 respectively. 70. COD: The following Table 21 represents the laboratory analysis results of baseline environmental monitoring. It shows that the level of COD was found highest in all the upstream and downstream samples. COD value varies from 4.00 to 32 mg/l, most of which exceeds the permissible limit (4mg/l) of Bangladeshi standard (except the D/S concentrations at SW_2 and SW_3). In the second quarterly environmental monitoring (Table 22), COD value varies from 4 to 72 mg/l. Higher COD values were found only in both upstream (72 mg/l) and downstream (64 mg/l) water samples of SW_4 where utensils washing and bathing activities of local people was observed during sample collection. The upstream COD of SW_1 was also found higher (20 mg/l) than the acceptable limit.

71. BOD: Natural waters will have a BOD of 5mg/l or less. BOD directly affects the amount of dissolved oxygen in rivers or streams. The greater the BOD, the more rapidly oxygen is depleted in the stream. During the baseline environmental monitoring, the BOD values vary between 1.10 to 2.20 mg/l in only three out of eight collected water samples. No BOD value was found in five of the collected water samples, indicating less pollution load on water. The results of second quarterly environmental monitoring show the BOD values vary between 1 to 20 mg/l in eight collected water samples. Higher BOD values were found in both upstream (20 mg/l) and downstream (17 mg/l) water samples of SW_4 where utensils washing and bathing activities of local people was observed during sample collection. ADB (1994) and GoB (1997) proposed BOD of 10 mg/l in irrigation water quality standards for Bangladesh. 72. DO: Dissolved Oxygen or free oxygen is needed for respiration of aquatic organisms. It is evident that the DO levels below 1 mg/l will not support fish population, thus, 5 to 6 mg/l are required for fish survival. DO values in our collected samples are varied between 6.90 to 7.64 mg/l during baseline environmental monitoring and 4.8 to 7.02 mg/l during second quarterly environmental monitoring, indicating average quality of river/canals water. 73. TDS: Total Dissolve Solids (TDS) refers to the sum of all the components dissolved in water. Noticeably, the water that contains too much dissolve matter is not for common uses, therefore, the standard limit set for Bangladesh is 500 to 1000 mg/l. TDS in the collected samples were varied from 29.40 to 184.20 mg/l during baseline environmental monitoring and 25 to 142 mg/l during second quarterly environmental monitoring which is slightly less than baseline concentration. Comparison between tested values and standard value shows higher difference of concentrations in upstream and downstream samples of SW_1 and SW_3, while the samples of SW_2 and SW_4 shows relatively closer upstream and downstream concentrations during baseline environmental monitoring. During second quarterly environmental monitoring, higher difference of concentrations in upstream and downstream samples was found inSW_4 only while the samples of SW_1, SW_2 and SW_3 showed relatively closer upstream and downstream concentrations. Overall, the collected water samples showed TDS concentrations of less than 200 mg/l, thus indicating the water moderately suitable for common use. 74. TSS: The level of TSS found in the samples range between 58 to 224 mg/l during baseline monitoring while 7 to 15 mg/l range was found during second quarterly environmental monitoring which is quite low compared to the baseline concentration. However, the set standard is 150 mg/l. Accordingly, the downstream concentration of SW_1 and SW_3 exceeds the standard limit during baseline monitoring (158 and 224 mg/l respectively) 75. Turbidity: Turbidity values of the surface water samples range between 9.0 to 296 NTU during baseline monitoring and reduced to 1.04 to 37.3 NTU during second quarterly environmental monitoring. However, the set standard value is 10 NTU. All the collected samples show higher concentration of turbidity during baseline monitoring while only SW_2 show higher concentration of turbidity due to its shallow water depth and local people and cattle movement by foot crossing the canal during second quarterly environmental monitoring. 76. Oil and Grease: The concentration of oil and grease in most of the surface water sample were found 8 to 35 mg/l in the surface water sample which is beyond the standard limit for
32
Construction of Single Line Dual Gauge Railway Track from Dohazari to Cox’s Bazar via Ramu and Ramu to Gundum Near Myanmar
Bangladesh (< 1 mg/l). During second quarterly environmental monitoring, the oil and grease concentration reduced to less than 2 mg/l which is slightly beyond the standard limit for Bangladesh (< 1 mg/l). At SW_2, the upstream concentration was found 3.6 mg/l. In the selected surface water bodies, water usually used for irrigation, fishing and sometimes washing utensils and bathing purposes which give an indication of slightly higher level of oil and grease concentration. 77. pH: There is less significant version of pH in various sampling stations and the tested samples ranged from 6.80 to 7.57 during baseline monitoring and 6.9 to 7.3 during second quarterly environmental monitoring. The set standard is 6.5 to 8 .5 (FAO, 1992) indicating suitability of water for common purposes.

79. From the Table 23, it can be seen that, parameters like Temperature, TSS, Turbidity and Oil and grease shows a decreasing trend whereas BOD shows an increasing trend from baseline to second quarterly monitoring. DO and TDS are also showing a decreasing trend except for the sample SW_3 D/S (DO) and SW_1 D/S and SW_3 D/S respectively. In case of COD, three out of eight samples are showing increasing trend (SW_1 U/S, SW_4 U/S and SW_4 D/S), another three is showing decreasing trend (SW_1 D/S, SW_U/S and SW_3 U/S) and the rest
35

two remain unchanged (SW_2 D/S and SW_3 D/S). In case of pH, half of the samples showing an increasing trend whereas other half is showing a decreasing trend. v) Analysis of Surface water quality measurement Lot 2 80. Analysis of Surface water quality measurement Lot 2 (September, 2018): During the second quarter, Bangladesh Council of Scientific and Industrial Research (BCSIR) organization in Chattogram has tested the required parameters from the submitted samples and provided test reports enclosing in their official letter heading. Based on the test report, following parameter wise brief descriptions are given. 81. COD: The following Table 24 represents the laboratory analysis results. It shows that the level of COD, was found highest in most of the upstream and downstream samples. During this study, COD value varies from 0.00 to 52.00 mg/l that exceeds the permissible limit (4mg/l) of Bangladeshi standard. The found COD values are harmful for the aquatic organism and the water only can be used for irrigation purposes. Noticeably, no construction activity has been started yet nearby Bakkhali River but still found a higher concentration (52mg/l & 24mg/l). In this regard, the river water might be affected in the upstream with the industrial effluent and our project activity is not liable for this level of COD concentration at the surface water. 82. BOD: Unpolluted, natural waters will have a BOD of 5mg/l or less. BOD directly affects the amount of dissolved oxygen in rivers or streams. The greater the BOD, the more rapidly oxygen is depleted in the stream. Accordingly, the study shows the BOD values that varies between 0.0 to 8.0 mg/l with less deviation means good quality of river or stream water. The highest value recorded was 8.0mg/l in the upstream water sample of the Bakkhali River. However, ADB (1994) and GoB (1997) proposed BOD of 10 mg/l in irrigation water quality standards for Bangladesh. 83. TDS: Total Dissolve Solids (TDS) refers to the sum of all the components dissolved in water. Noticeably, the water that contains too much dissolve matter is not for common uses, therefore, the standard limit set for Bangladesh is 500 to 1000 mg/l. TDS in the collected samples were varied from 45.24 to 182.42 mg/l. Comparison between tested values and standard value show a small variation and the field value is less than the standard acceptable limit thus the river/canals water is moderately suitable for common use. 84. DO: Dissolve Oxygen or free oxygen is needed for respiration of aquatic organisms. It is evident that the DO levels below 1 mg/l will not support fish population, thus, 5 to 6 mg/l are required for fish survival. DO values in our collected samples are varied between 6.4 to 7.76 mg/l, indicates the average quality of river/canals water. 85. TSS: The level of TSS found in the samples range between 4.0 to 310.0 mg/l, however, the set standard is 150 mg/l. Noticeably, most of the tested samples exceed the standard limit and found highest 310.0 mg/l at the Bridge location 96. 86. Turbidity: Turbidity values of the surface water samples range between 21.3 to 288.0 NTU whereas the set standard value is 10 NTU. All the collected samples show higher concentration of turbidity. The increased turbidity could also have been due to the monsoon rains. The higher concentration might be because of dissolve particulate matter including sediment from the upstream due to surface runoff - especially clay and silt, fine organic and
36
Construction of Single Line Dual Gauge Railway Track from Dohazari to Cox’s Bazar via Ramu and Ramu to Gundum Near Myanmar
inorganic matter, soluble colored organic compounds, algae, and other microscopic organisms. The project activity is not harming the existing water quality anyway. 87. Oil and Grease: The concentration of oil and grease were found higher (ranges from 7.0 to 65.0 mg/l) in the surface water sample which is beyond the standard limit (<1 mg/l) for Bangladesh. The selected surface water usually used for irrigation, fishing, sometimes bathing and boating (both shallow engine and manual) purposes etc. were observed during sample collection. However, the set BD standard is applicable for drinking water on the other hand 10mg/l is applicable for industrial discharge. Since, the construction activities are not started in these selected sampling locations, therefore, project impact will not be accounted here right now. The higher concentration of Oil & Grease in the tested water may be caused due to spillage of oils from the engine boats or from the irrigation pumps.

88. Analysis of Surface water quality measurement Lot 2 (December, 2018): Rivers, canals, and ponds water quality within the proposed alignment of the DCRP Lot 2 is one of the key concerns as they are used for drinking and domestic purpose, irrigation and aquatic life including fish and fisheries. Thus, it was a requisite to test surface water quality of the project area. Accordingly, four sampling stations were identified using GPS coordinates, with one station upstream and one downstream of the crossing area, for a total of 8 sampling points along the proposed alignment (See Appendix 5 for locations). 89. After collecting surface water quality samples, the sealed bottles were sent to the Department of Public Health Engineering (DPHE) and Bangladesh Council of Scientific and Industrial Research (BCSIR) Dhaka laboratory for testing the necessary parameters including Temperature, Turbidity, pH, TDS, TSS, Fe, DO, COD, BOD, Total P, Oil, and Grease. 90. COD: The following Table 25 represents the laboratory analysis results. It shows that the level of COD, was found highest in most of the upstream and downstream samples. During this study, COD value varies from 20.00 to 176.00 mg/l that exceeds the permissible limit (4mg/l) of Bangladeshi standard. Higher COD levels mean a greater amount of oxidizable organic material in the sample, which will reduce dissolved oxygen (DO) levels. A reduction in DO can lead to anaerobic conditions, which is deleterious to higher aquatic life forms. Noticeably at BR 96 the concentration was found higher (176 mg/l). Moderated deviation of river COD values refers moderate quality of the river water for fish or other aquatic organisms and applicable for irrigation purposes. Additionally, there is less chances to affect the water quality due to bridge construction since, proper barricading is provided and no chemical solvent is thrown away to the canal or river water. 91. BOD: Unpolluted, natural waters will have a BOD of 5mg/l or less. BOD directly affects the amount of dissolved oxygen in rivers or streams. Accordingly, the study shows the BOD values that varies between 5.0 to 46.0 mg/l. Among the four sampling stations, BOD found highest at BR 96 downstream sample (46mg/l) and BR 161 (12 & 16 mg/l for up and down stream water). However, ADB (1994) and GoB (1997) proposed BOD of 10 mg/l in irrigation water quality standards for Bangladesh. When BOD levels are high, dissolved oxygen (DO) levels decrease because the oxygen that is available in the water is being consumed by the bacteria. Since less dissolved oxygen is available in the water, fish and other aquatic organisms may not survive. Noticeably, canal was blocked with the sand bags temporarily for construction and water become stagnant at these points, therefore, BOD is found higher. Additionally, water quality is not affected anyway due to construction activity at any surface water body locations. The water can be used only for bathing, fishing and agricultural activities. Noticeably, this blockage helps the farmer for their upcoming irrigation during the summer. 92. TDS: Total Dissolve Solids (TDS) refers to the sum of all the components dissolved in water. Noticeably, the water that contains too much dissolve matter is not for common uses, therefore, the standard limit set for Bangladesh is 500 to 1000 mg/l. TDS in the collected samples were varied from 33.00 to 14500.00 mg/l. Only at BR 96 location sample shows the highest level of TDS caused by the presence of potassium, chlorides and sodium. These ions have little or no short-term effects, but toxic ions (lead arsenic, cadmium, nitrate and others)
38
Construction of Single Line Dual Gauge Railway Track from Dohazari to Cox’s Bazar via Ramu and Ramu to Gundum Near Myanmar
may also be dissolved in the water. Despite this location, other tested values show a small variation and the field value is less than the standard acceptable limit thus the river/canals water is moderately suitable for common use. 93. DO: Dissolve Oxygen or free oxygen is needed for respiration of aquatic organisms. It is evident that the DO levels below 1 mg/l will not support fish population, thus, 5 to 6 mg/l are required for fish survival. DO values in our collected samples are varied between 3.87 to 6.24 mg/l, indicates the average quality of river/canals water. BR 96 shows the lowest DO concentration it is because of highest BOD and COD values and lack of natural flow of water. 94. TSS: The level of TSS found in the samples range between 12.0 to 18.0 mg/l, however, the set standard is 150 mg/l. Noticeably, most of the tested samples found within the standard limit. 95. Turbidity: Turbidity values of the surface water samples range between 10.8 to 61.70 NTU whereas the set standard value is 10 NTU. All the collected samples show higher concentration of turbidity. Too much algae or sediment in lakes and streams can make them unsuitable for recreation and aquatic life. Turbidity is caused by particles suspended or dissolved in water that scatter light making the water appear cloudy or murky. 96. Oil and Grease: The concentration of oil and grease were found slightly lower than 2mg/l in the surface water samples. Under this amount of oil and grease in every sampling location can induce skin rashes and scabies who take bath from Bakkhali River. It will be wise to note that the oil and grease have skin penetration properties. However, project activity has no significant impact due to taken precautionary measure at the construction area i.e. installation proper barricading, signage, restriction of dumping any chemical or washing equipment at the BR locations. The selected surface water is suitable for irrigation, fishing, sometimes bathing and boating (both shallow engine and manual) purposes etc. were observed during sample collection.

A comparison is made shown in Table 26 based on quarterly reports (September and December 2018). BOD and COD values fond higher compared to September data. There is no significant changes in the DO concentration. The highest TDS value found in the December 2018. TSS concentration found higher in September quarter and Turbidity values change noticeably as ranges from 10.8 to 288.0 NTU within the nine months period. Finally, oil and grease concentration was found relatively higher in the month of September at most of the sampling locations. 98. Remarks: Considering the three quarterly reports, there is no significant changes found within the DCRP Lot 2 sampling locations or specifically BR locations. Despite some abrupt changes in few parameters, overall there is no noticeable changes observed. Therefore, it can be concluded that, the project activity has no significant on the surface water quality. Additionally, as per precautionary measure, at every active BR location safety in charge installed proper barricading, signage and restrict dumping of any chemical or washing equipment at the surface water body.

Ground water samples were collected from 14 sampling stations (14 tube wells around bridge crossings; and one sample per tube well). Prior starting the sampling, the team dressed appropriate PPEs and sterilized the faucet of the deep-well for 2 minutes and then took the samples. The parameters that were measured are pH, total phosphate (TP), arsenic (As), iron (Fe), manganese (Mn), and E-coli, Oil & Grease. All collected samples were stored in plastic sampling bottles, except E-coli and Oil & grease (amber bottle) then put some marking to identify them later before analysis and stored according to standard methods and analyzed within 24 hours of being collected at an ISO14000-certified laboratory.

Construction of Single Line Dual Gauge Railway Track from Dohazari to Cox’s Bazar via Ramu and Ramu to Gundum Near Myanmar iii) Analysis of groundwater quality Lot 1 102. Table 27 shows the groundwater sampling locations. The selected four samples i.e. GW_1, GW_3, GW_5 & GW_7 were collected from four proposed stations of the DCRP (Deep well of local people at the vicinity). Two of the remaining selected three samples i.e. GW_4 & GW_6 were collected from local people’s tube well near to the river or canal crossing bridge area. GW_2 water sample was collected from the nearby deep well of the proposed Satkania station (Ch 8+760). The sampling site is still a virgin land, surrounded by rice fields where no construction activity has been started yet. 103. Water for human consumption should be undergone regular physicochemical tests. Physicochemical properties are high priorities in determining acceptability, although they may have little bearing on whether the water is safe to drink or not. Generally, the standards used to evaluate the suitability of water for drinking and domestic purposes are more restrictive than those that would be applied to water for other purposes. 104. Groundwater samples were collected from 7 tube wells near the project corridor on 24th of September, 2018. The laboratory tests performed were for pH, Arsenic (As), Manganese (Mn), Iron (Fe), Phosphorus (as Phosphate), oil and grease, and E. coli and Temperature was recorded simultaneously during sample collection. The collected samples were sent to the Bangladesh Council of Scientific and Industrial Research (BCSIR) for testing the required parameters. Results of the groundwater testing are shown in Table 28.

105. The ground water test results for some parameters (As, Mn, Oil and Grease) received from BCSIR Chattogram Lab during baseline environmental monitoring has been found erroneous by the team of engineers. As per instruction of the team of engineers, the contractor has changed testing laboratory to Department of Public Health Engineering (DPHE), Dhaka from December, 2018. 106. Arsenic (As): Arsenic was not found in any of the collected water samples. The Bangladesh Standards for Drinking water (ECR, 1997) is 0.05 ppm and WHO guideline is 0.01 ppm for Arsenic in any water sample. Considering this, it can be concluded that the water samples are arsenic free. However, these results cannot be taken into account as BCSIR Laboratory has not been approved by the team of Engineers. So, the contractor has discarded the BCSIR Laboratory and opted DPHE (Department of Public Health Engineering) laboratory for future tests. 107. Iron (Fe): Concentrations of Iron have been found from 0.07 to 10 ppm (Table 28). The standard value ranges from 0.3 to 1.0 ppm for Bangladeshi perspective. Three out of seven samples were found exceeding the standard iron concentration; GW_2, GW_4 and GW_5. Although high iron in drinking water is not a major health problem, it may be unacceptable to users at such high concentrations. 108. Manganese (Mn): Manganese on the other hand, is regarded as a potential health problem in waters and WHO have set a guideline value of 0.5 mg/l for this element while BD sets 0.1 mg/l. The tested report shows (Table 28) the Mn value was found below the detection limit considering all the samples. However, these results cannot be taken into account as BCSIR Laboratory has not been approved by the team of Engineers. So, the contractor has discarded the BCSIR Laboratory and opted DPHE (Department of Public Health Engineering) laboratory for future tests. 109. P (as Phosphate) and pH: The concentrations of P (as Phosphate) found in the tested sample rage from 0.20 to 7 ppm, however, the standard value sets as 6.0ppm for drinking water. Accordingly, two (GW_1 and GW_3) of the seven water samples were found to have higher phosphate concentration than the permissible limit. However, groundwater samples meet the pH standards, however, the found values vary from 6.20 to 7.81 (Table 28). 110. Oil & Grease: Oil and grease concentrations found in the samples ranging from 0.52 to 1.25 mg/l which is higher than the standard 0.01 mg/l (Table 28). This may have happened as most of these tube wells are used to wash cooking utensils having some amount oil attached on

its surface. However, these results cannot be taken into account as BCSIR Laboratory has not been approved by the team of Engineers. So, the contractor has discarded the BCSIR Laboratory and opted DPHE (Department of Public Health Engineering) laboratory for future tests. 111. E.Coli: Despite the significant improvement in bacterial quality afforded by groundwater over surface water sources, many ground water sample from tube wells in Bangladesh show higher than acceptable concentrations of bacterial contaminants. The tested report shows that only one tube well had significant levels of E.Coli which is >1100/100 ml whereas the standard set as 0 (Table 28). The reports indicating that, the supplied water sample are contaminated with thermo-tolerant Escherichia Coli. This appears related to a number of factors, including proximity of latrines or drains to the tube wells, tube well depth or method of completion, and factors such as the practice of tube well priming. iv) Analysis of groundwater quality Lot 2 112. Analysis of groundwater quality (September 2018) of Lot 2: Groundwater samples were collected from 7 tube wells near the project corridor on 21st of September 2018 (See Table 27 for locations). The laboratory tests performed were for Temperature, pH, Arsenic (As), Manganese (Mn), Iron (Fe), Phosphorus (as Phosphate), Oil and grease, and E. coli. The collected samples were sent to the Bangladesh Council of Scientific and Industrial Research (BCSIR) at Chattogram Lab for testing the required parameters. Results of the groundwater testing are shown in (Table 29). Bangladesh Council of Scientific and Industrial Research (BCSIR), Chattogram, has tested the required parameters from the submitted samples and provided test reports enclosing in their official letter heading. 113. Arsenic (As): The level of Arsenic (As) was found 0.00ppm in the tested water samples which complies the Bangladesh Standards for Drinking water (ECR, 1997) as 0.05 ppm and WHO guideline 0.01 ppm in all samples (Table 29). Considering this level of As found in the samples indicating the potability of water quality and workers are free form carcinogenic effect in future. 114. Iron (Fe): All the tested groundwater samples contain higher concentrations of Fe accept GW_04 and GW_06 (< 0.1 ppm) while the standard value ranges from 0.3 to 1.0 ppm for Bangladeshi perspective. Concentrations have been found from ranges from 0.1 to 2.80 ppm (Table 29). Although high iron in drinking water is not a major health problem, it may unacceptable to users at such high concentrations. 115. Manganese (Mn): Manganese on the other hand, is regarded as a potential health problem in waters and WHO have set a guideline value of 0.5 mg/l for this element while BD sets 0.1 mg/l. The tested report shows (Table 29) the Mn value found under detection level which meets both BD and the WHO guideline. The inhalation higher concentration Mn to the human body might cause brain effect. Since, the tested water doesn’t contain this element meaning we are safe and environment is well maintained. 116. TP (as Phosphate) and pH: The concentrations of TP (as Phosphate) found in the tested samples rage from 0.30 to 5.60 ppm, however, the standard value sets as 6.0ppm for drinking water. Accordingly, the concentration of P was less than the permissible limit. Similarly,
45
Construction of Single Line Dual Gauge Railway Track from Dohazari to Cox’s Bazar via Ramu and Ramu to Gundum Near Myanmar
groundwater samples meet the pH standards, however, the found values vary from 6.20 to 7.84 (Table 29). The water is suitable for all household purposes. 117. Oil & Grease: Oil and grease concentrations found in the samples range between 0.3 to 2.0 mg/l which is higher than the standard 0.01ppm (Table 29). Further testing is required in order ensure the oil and grease amount found this time. The non-point sources of oil & grease tend to be in the form of pesticides and nutrients that enter the soil as a result of intense agricultural operations or the widespread use of road salts and chemicals. As the groundwater sampling stations are located nearby area of agricultural land and also salt firming is common here which can be a major source of oil & grease in groundwater. 118. E.Coli: The tested report shows 0.0 CFU/100ml levels of E.Coli which meets the standard set as 0. The water is potable for all users.

5) Drinking water Quality 120. Based on the Engineers requirement in the month of September one sample (from CCECC- MAX JV Camp) and in December two samples (from Ramu Lab and Ramu Yard) were collected additionally in order to check the drinking water quality. The objective of these drinking water samplings was to verify existing water quality and make comparisons against a standard. Besides, it is essential to know the status of the drinking water since more than 100 workers are dependent on these sources. The measured parameters are such as pH, DO, TDS, TSS, Salinity, As, TC, FC, Fe, and Temperature. The collected sample were tested at the

6) Noise Meter 126. The Engineers gave approval to buy a noise meter which will be used on a regular basis in the field level (Ref: SMEC/5060126/CSC1/2018-745(DM). CCECC-MAX JV has been issued a work order to purchase the requested noise meter model (SL-4033SD LUTRON) and expected to be reached at the site very soon.
7) Flora and Fauna 127. During our visit on 23rd April,2018 we have seen The Chunati Reserve Forest harbours a rich floral resource of Garjan (Dipterocarpus spp.) and Boilam (Anisoptera scaphula) trees etc. We visited Medhakachhapia and Fasiakhali reserve forest and talked with the local people on 23rd April, 2018.The opined that movement of elephant (Elephas maximus) is frequent.Oher faunas wher are rarely seen are - slow loris (Nycticebus bengalensis), rhesus macaque (Macaca mulatta), capped langur (Trachypithecus pileatus), mouse deer (Tragulus javanicus), and Rufous-tailed hare (Lepus nigricollis).

B. Construction Period Qualitative Assessment 1) Environmental Issue EMP_2.6/H-6.1 (e.g. Noise attenuation measure) 128. According to the EMP 2.6, Noisy works may not be occurred near to the sensitive areas like residents, schools, religious places and hospitals. But during the pilot pile work at BR 124 (Ch. 73+706) which was located just beside of a local mosque where various machines were observed working for instance Rotary rigging, excavator, crane, generator etc. (Photo 1). During the reporting period, other noise sources also observed within the construction sites (Photo 2 to 4) 129. Due to lack of noise meter, it was not possible to measure the exact noise level during the field visit. However, during the quarterly noise measurement in September at BR 124 beside the sensitive receptor, it was found 69.41 dBA (Day) and 63.17 dBA (Night). Considering this zone as commercial, the standard is 70 dBA (Day) and 60 dBA (Night) for Bangladesh, meaning noise generation was around the standard limit. Additionally, due to work pressure at BR 124, the 3rd quarterly Noise monitoring in December has been performed at this site again. Data analysis was not performed yet, therefore, 3rd quarterly measurement result is not incorporated in this report. However, no objection found either from the mosque authority or local inhabitant nearby due to noisy work, therefore, no necessary immediate measures were taken on the spot. Considering the Napitkhali camp, the retention wall has been constructed which will act as a good noise barrier. Besides, usually tin shed was provided for generators at the site. 130. The Engineers gave approval to buy a noise meter which will be used on a regular basis in the field level (Ref: SMEC/5060126/CSC1/2018-745(DM). CCECC-MAX JV has been issued a work order to purchase the requested noise meter model (SL-4033SD LUTRON) and expected to be reached at the site very soon. 131. Environment Specialist along with HSSE team has been waiting to receive the digital noise meter. The noise measurement will take place during every field visit. Then necessary measure can be taken if exceeds standard limit, for instance, establishment of noise barrier/enclosure to minimize or reduce the noise level near to the residential area and providing hearing protecting device to the workers in order to comply with the EMP. Toolbox talk and training session will be conducted to raise awareness among the worker to maintain safe working environment and safe themselves.
2) Air quality and dust control 132. According to the Subsection H: Environment Safeguard, it is stated that, all roads, permanent or temporary, pukka or katcha, that become dusty and all areas where construction related activities are carried out, need to ensure necessary suppression measures i.e. watering, sweeping or other measures approved or directed by the Engineer. However, due to monsoon period the weather was humid and rainy (I.e. July to mid- October). Therefore, no dust suppression measures were taken or needed at all. Besides, rainy weather makes the work more difficult to progress (Photo 5 to Photo 8). During month of July to October, apparently there was no dust suppression measure taken due to frequent and torrential rain. Besides, humidity was high as well. Consequently, after the monsoon,
50
Construction of Single Line Dual Gauge Railway Track from Dohazari to Cox’s Bazar via Ramu and Ramu to Gundum Near Myanmar
CMJV has been decided to ensure dust control measure. Overall, 5 vehicles have been using for dust control on a daily basis (2 times per day) to spread water at different sites. Approximately a total of 27, 000, 00 L of water has been spread throughout the month and covered a total of 8-10 Km daily including local road (Photo 26 to Photo 30). The information was collected informally from the field (CCECC part). However, the contractor doesn’t keep any record of dust control measure. CMJV’s higher official decided to keep maintain log book alike petroleum products from the next month which will be incorporated in the monthly report of January 2019. 133. Additionally, four air quality monitoring has been performed as quarterly basis at different sites (Photo 25). As the construction activity shifting on a regular basis for the good progress achieved by the Contractor, to define the impact of construction activity on the ambient air quality at different sites, same air monitoring stations for each and every sampling quarter was not possible to maintain. But since the camp sites will not shift, the Contractor will maintain the same sampling stations particularly where there are crushing plants or other polluting plants. 134. Weekly inspection is being conducted by the environment specialist in order to monitor and report environmental and safety noncompliance and compliance issues. Additionally, a log book will be maintained from the month of January 2019.
3) Environmental Issue EMP_2.4/H-6.3 (e.g. Protection of Wetlands/Ponds/Rivers/Canals) 135. Considering this clause 2.4 mentioned in the EMP as “Undertake protection of watercourses”, the contractor (CCECC-MAX JV) of Lot 2 has been working on to ensuring the protection of all wetlands, ponds, rivers and canals lied under the project boundary throughout Construction period of New Dual Gauge Railway Line from Dohazari to Cox's Bazar via Ramu (DCRP- Lot 2). 136. Construction activity i.e. pilot pile, working pile, and pile cap construction was performed at the BR 155 (Bakkhali River), BR 124, BR 120, BR 129, BR 130, BR 147, BR 161 and BR 162 over the last six months period but the earth moving in the vicinity of watercourses were kept to a minimum to avoid sedimentation and contamination from fuel and lubricants. Noticeably, considering the wetlands protection, CMJV has been working on ensuring the quality of water resources at bridge locations mainly. 137. There was no identifiable construction or earthwork activities were observed yet that might affect watercourses anyway. During the pilot pile (i.e. pilot pile 8) and working pile (i.e. working pile 48), water body near the Bridge construction area was not affected anyway. Noticeably, during the pilot pile/work pile, proper barricading was observed nearby water bodies to protect their natural flow and quality of water. However, at some point due to lack of flow of water (very narrow khal) the diversion road was made on the surface water body on a temporary basis (i.e. BR 129, 130, and 161). Besides at some points contractor put together concrete rings to maintain the flow of water bodies (i.e. BR 120, BR 124, and BR 162). The Photographs show the protection measures and existing status of water bodies (Photo 31 to Photo 35). Additionally, MAX has been constructing a temporary concrete based bentonite holding tanks on the ground in order to avoid contamination of soil as well as potential surface water bodies adjacent to the pilot pile area (i.e. BR 161, BR 147, BR 155, &
51
Construction of Single Line Dual Gauge Railway Track from Dohazari to Cox’s Bazar via Ramu and Ramu to Gundum Near Myanmar
BR 162). The contractor was clearly informed about the importance of the surface water bodies to protect from any kind of pollutions. 138. Additionally, three surface water quality monitoring surveys have been conducted on a quarterly basis at different bridge locations i.e. BR 124, BR 96, BR 161, BR 147 & BR 155 (Photo 36) in order to monitor their exiting surface water quality and to know any potential impacts due to constructions. The water samples were collected to measure parameters
such as pH, Turbidity, Temp (°C), DO, BOD5, COD, TSS, TDS, and Oil & Grease. 139. New bridge construction will be continued at new places, therefore, the HSE team will ensure to protect wetlands and surface water quality near bridge locations. Regular visit will be conducted as well along with consultant and fill up approve checklist.
4) Environmental Issue H_6.6 (Servicing and Operating Equipment) 140. The work regarding servicing and operating equipment have been carried out by the CMJV’s experienced mechanical personnel in such a manner so that near rivers, streams or other bodies of water will not be affected and get polluted with gasoline, diesel fuel, oil, grease, or surplus or disposable materials. 141. During the field visit, a few servicing activity was observed at the Link road area, Ramu Camp, BR 124, BR 129 and Napith Khali camp. However, the safety team informed to the site engineer regarding the safe servicing and operating activities. No major servicing was observed, but minor because of using brand new vehicles and equipment during the operations which are all equipped with modern technology (CCECC part). A total of 314 (CCECC- 169 & MAX- 145) different types of equipment were used at different sites at the end of November 2018 for various activities and held very common servicing which maintained on a regular basis. In December there were 214 fully functional equipment mobilized to the field and few were under servicing due to break down at once on site. 142. No major servicing was observed, but minor because of using brand new vehicles and equipment during the operations which are all equipped with modern technology. A total of 314 (CCECC- 169 & MAX- 145) different types of equipment are listed to be used (i.e. some are idle at the CCEECC camp & some are yet to come but owned) or have been using at different sites for various activities and held very common servicing which maintained on a regular basis. However, site engineers, mentioned that for major servicing they usually send their vehicles/machines to the nearby garage or company’s own servicing area for further repairing activities. Besides, site engineers were instructed to perform servicing and operating equipment carefully in urgency and avoid pollution due to oil spillage, gasoline, diesel fuel, grease, or surplus or disposable materials. Additionally, mechanic have been informed clearly that they should not perform any servicing of machines or equipment near rivers, streams or other bodies of water to avoid water pollution. 143. Mechanical department at both camp (i.e. EMD workshop MAX site) site personnel and site engineers have been informed to perform servicing and operating equipment carefully in urgency and avoid pollution due to oil spillage, gasoline, diesel fuel, grease, or surplus or disposable materials. Additionally, HSE team will visit every site and keep informing mechanical engineers not to perform any servicing of machines or equipment near rivers, streams or other bodies of water to avoid water pollution.

5) Control of Petroleum Product 144. It is clearly stated in the specification H that all petroleum products need to be stored in a designated storage location i.e. fuel storage/tank, where any spillage can be safely maintained without contamination of surrounding area. Additionally, the storage site need to be established far away from the vicinity of streams, rivers or other bodies of water. Considering these requirements, the CCECC-MAX JV has been performing construction activities in such a manner so that they can comply with the specification. 145. Regarding the control of petroleum products, few non-compliance issues were recorded at different places. For instance, at various construction sites (i.e. bridge 124, 129, 130, 155, 161 & 162), the contractor usually uses temporary oil storage facility (i.e. plastic or tin made oil drum) in order to meet their essential oil demand (Photo 11). In this regard no oil abetment initiative was seen, however, no spillage or accident was reported due to momentary fuel oil storage facility at the sites. At Link road temporary oil usage facility was observed which was not complied with EMP, therefore the site engineers were informed to take permanent or at least some protection measures so that ground spillage can be prevented (Photo 10). On the other hand, at the Napith Khali camp, two oil tankers usually ensure their necessary fuel oil demand (i.e. fuel collected form the local fuel oil station) on a daily basis, therefore, no noncompliance issues have been found there (Photo 09 & 12). 146. The site engineer was instructed strictly before and during the field visit in presence of the Consultant team, to take necessary measures for instance, to install signage at the site indicating danger sign and oil storage area, arrange oil deep/spill tray under the oil container to avoid oil spillage to the ground or spill to the nearby area, provide fire extinguisher to avoid fire hazard. Besides, the identified noncompliance issues were informed to the responsible authorities to take recommended measures by preparing a report using photographs and send through email. Additionally, permanent cylindrical fuel oil storage tank having a capacity of 15,000 L was observed fully functional from December 2018 at Ramu camp wherever daily demand is around 3000 L (Photo 37 & Photo 38). On the other hand a permanent 2 cylindrical fuel oil storage tanks have been set (Photo 39 & Photo 40) to ensure fuel oil facility which is not functional yet. However, both stations have spill control capacity. 147. A regular site visit will be conducted in order to check whether the site engineer takes necessary measures or maintain their standards against non-compliance issues identified during every site visit. Additionally, spill abatement measures will be adopted as soon as possible after finishing their construction of fuel storage area.
6) Occupational Health and Safety 148. Occupational health and safety is one of the major construction issues that has been handling very carefully since the projected started by the CCECC-MAX JV in order to ensure workers welfare and safe working environment at the site. Therefore, workers safety issue in every aspects have been given first priority. A number of HSE officers have been engaged in order to perform and monitor workers health and safety. Over the last six months period, occupational health and safety measures were mainly observed at the bridge locations i.e.
53
Construction of Single Line Dual Gauge Railway Track from Dohazari to Cox’s Bazar via Ramu and Ramu to Gundum Near Myanmar
BR 96, BR 124, BR 120, BR 129, BR 130, BR 155, BR 161, BR 162, CCECC-MAX JV camp, and Ramu Camp. 149. Proper PPEs, signage and barricading: During the field visit, the HSSE team always tried to observe and ensure proper PPEs at the site while workers working at different sites. During the month of July, when the first pilot pile work started, there was lack of proper PPEs especially shoes and hand globes. Gradually, the situation have changed for the CCECC part. Proper signage and barricading was observed very frequently at various sites (Photo 41 & 42). On the other hand during the commencement of Ramu Camp there were lack of PPEs of the workers which is because of few workers were from the subcontractor part (Photo 13 & Photo 14). However, overtime proper PPEs were ensured for the workers. Proper signage and barricading at the Ramu Camp was ensured from beginning. Despite some non- compliance issues sometimes, most of the cases PPEs were ensured for the workers (Photo 55, 57, 58, 60 & 61). Apparently, non-compliance issues were raised due to engaging subcontractors at different site for various constructions. However, CMJV’s higher official was informed regarding that issue and they only ensure PPEs for their staffs only. As per ADB’s requirement, the main contractor is also responsible for ensuring the subcontractor’s compliance with all environment safeguard requirements including PPE’s. Accordingly, subcontractors have been informed clearly to ensure their workers PPEs otherwise they are not allowed to work at the site. Additionally, proper signage and barricading was observed most of the construction sites over the whole last six months period. 150. Electrical and mechanical safety: From the Photo 15, it is evident that electrical safety was not properly ensured the site. Photo 16 shows the lack of proper PPEs of 2 welders. Additionally, sometimes found non-comply with the IEC 6066, BDS 1360- 1992, & BDS- 1436- 1994 codes. Therefore, the electrical department personnel was informed to either change electrical appliances, ensure proper insulation, and better face shield while electrical welding is performed. Additionally, at the MAX part, it was found haphazard conditions surrounded with electrical wears at the sites. Safety officer was informed to ensure proper housekeeping and if possible change old electrical appliances. However, it will take some time to improve electrical and mechanical safety at the workplace. 151. Drinking water, toilet and First aid Facility: CMJV has been working on ensuring primary facilities such as potable water at all construction sites, and hygienic toilets. Unfortunately, due to lack of permanent workers at the bridge construction sites, therefore, there was lack of proper toilet facility (Photo 20). Besides, readily accessible first aid facility was observed at work places. Noticeably, temporary accommodation facility was observed for workers at bridge 155, 147 and 162 since, they stayed for long time. Therefore, proper toilet and potable water facility was ensured. 152. Housekeeping and others: Photo 19 represent a lack of proper housekeeping at Ramu Laboratory area. It was because of under construction but proper initiative was taken later on. Additionally, Photo 17 shows a potential suspect of a child labor at the construction site by the HSE manager. To clarify this issue, the Foremen of the Team (under whom the suspected child labor has been working) has shown the National ID of the Suspect. Which clearly defined that, the suspect was not child labor. Therefore, he asked proper document from the subcontractor and stopped his work temporarily. Finally, Photo 18 reveal the
54
Construction of Single Line Dual Gauge Railway Track from Dohazari to Cox’s Bazar via Ramu and Ramu to Gundum Near Myanmar
unsecured work on height. There was lack of full body harness for the workers. Photo 43 to Photo 56 shows a good example of proper housekeeping at different site. CMJV has been aiming to ensure that kind of proper housekeeping for all sites, however, it will take a little bit more time to establish. Photo Photo 54, shows an example of awareness training and tool box talk to the workers where safety officer provides necessary guidelines for safe work avoid occupational hazards. Finally Photo 62 represents the HIV-AIDS awareness action and orientation program conducted monthly basis by a NGO called EBS at different sites of the DCRP Lot 2.
7) Environmental Issue EMP_2.3/H-6.11 (Protection of top soil and erosion) 153. As defined in the EMP, Clause 2.3, it is necessary to implement topography, landscape and soil plans. Accordingly, CCECC-MAX JV has been working on protecting and storing top soil while excavated during the stripping work. Additionally, some erosion control measures were observed at different sites as well. 154. During the last six months few clearing, grubbing and stripping activities were performed where CMJV stored the top soil on the surface of the ground in a linear pattern adjacent to the filled/ developed land between RoW so that soil can be used later on used as per embankment preparation. It can be seen that top soil management practices at Ch- 88, 89, 83, 84, 79, 80, 77, 68, 69, 72, 73, 97, 98 and 100. Table 34 shows the various earthworks activities that have been performed throughout the last six months period 155. During the month of November and December 2018, some clearing, grubbing and stripping activities were performed where they stored the top soil on the surface of the ground in a linear pattern adjacent to the filled/ developed land between RoW so that soil can be used later on used as per embankment preparation. Photo 47 to Photo 53 & Photo 59 shows some example of top soil management practices at different changes (Table 34) i.e. Ch- 88, 89, 83, 84, 79, 80, 77, 68, 69, 72, 73, 97, 98 and 100. Overall a total of around 77,940.0 m3 top soil was stored temporarily for further use and covered an area of approximately 6.81 Km (Table 34). However, top soil stockpiling and/or disposal of material is not placed in any area where natural drainage or storm water could pond and become stagnant, or where could erode the material and cause silting of the adjacent area or of any natural or manmade water course.

Grievances and Complaints 157. During the reporting period, no complaints has received or addressed due to the construction activity. But if in near future GRC receive any complaints, then the date of receipt of complaint; complainant’s name and location; nature of complaint; response provided; date of providing response; and whether the grievance has been redressed or not will be reported.
UNANTICIPATED SAFEGUARD ISSUES 158. During the reporting period from 1st July of 2018 to 31st December of 2018, no such anticipated safeguard issues came across.
CONCLUSION
A. Overall Progress with Implementation of Environmental Safeguard Measures 159. The environmental awareness creation, particularly regarding the direct construction impacts and especially for health, environmental pollution and safety issues are important. The need to develop self-regulation of the contractors will have to be emphasized, with the consultant’s supervisory role that to be in conformity the relevant Environmental Clauses (Section 6, Subsection H: Environmental Safeguards of contract technical specification) incorporated in the construction contracts and national legislation. 160. Overall during July 2018 to December 2018, environmental team has performed different activities related to environmental issues such as, visited different sites very frequently, monitoring site activities and record activities that might affect existing environment and inform appropriate personnel to take necessary measures to avoid environmental pollution and ensure work place safety. Despite some non-compliance issues at different sites, overall the construction activities have been progressing smoothly without hindering environmental quality and putting safety at the first place of this development. Furthermore, environmental safeguard awareness programs were conducted among the workers and necessary instructions were given to take effective measures to avoid environmental pollutions and become aware about our precious environment. 161. Additionally, quantitative assessment like air, water, and noise quality have been performed two times as quarterly basis in the reporting period and analyzed data presented here for better understanding of project effect to the environment. Based on the analysis, it can be concluded that, the construction activities have no significant impact on any of the environmental components. 162. Based on the present status, further next level planning needs to be executed. Proper planned activities could rather help to implement the EMP efficiently with minimum impact on the exiting environment. The disputes identified in the report, from those both the Engineer & the Contractor shall take lessons and advice the Contractor to work more effectively. However, cooperation from every one related to this project is very essential to make this project successful with minimum impact to the environment.
