Padma Multipurpose Bridge Project

1.5.5 ADB Study (ADB PPTA May 2007)54. The ADB Environmental Assessment study had taken into account the ADB Guidelines relevantto the project and reviewed and analyzed the existing relevant legislations of Bangladesh, e.g., theEnvironment Conservation Act, 1995 (ECA,1995), the Environment Conservation Rules, 1997(ECA,1997), the Bangladesh Wildlife (Preservation) Order, 1973, the Forests Act, 1927, the Protectionand Conservation of Fish Act, 1950 and the Protection and Conservation of Fish Rules, 1985.55. Baseline considered for ADB study had been Climate, Air Environment, Noise Environment,Topography, Geology and Soil, Seismicity, Water Resources, Hydrology, River Sediment, Landuse,Fisheries, Wildlife, Vegetation, Forests, Rare or Endangered Species, Land Acquisition, EconomicCharacteristics, Social Infrastructure, Health and Safety and Historical and Cultural Resources.Primary environmental quality baseline monitoring was done for surface and ground water, andRiverbed dredged material.Components Parameters Site of Sample CollectionSurface waterqualityGround waterqualityColor, temperature, turbidity, EC, hardness,chloride, nitrate, BOD, COD, pH, TDS, DO, SSand Grease & Oil, heavy metalsColor, temperature, turbidity, EC, hardness,chloride, nitrate, BOD, COD, pH, TDS, DO, SSand Grease & Oil, heavy metalsMoisture, Fe, Pb, Cr, Zn, Cu, Hg Ni, As, Cn,Se, Cd, and Mn5 locations5 locationsRiver bed14 locationsmaterial56. Findings of the May 2007 ADB Environmental Assessment study had focused on the aspectsunder the following two major heads:Valuable Ecosystem Components (VECs): Terrestrial and Aquatic Flora and Fauna includingLocal and Migratory Avian Species and Endangered Species; Landuse (Agricultural andFallow lands); Water (Water Quality of River and Ponds, Seizure of Ponds and GroundWater); Drainage (Flooding and Water-logging, Sedimentation, River Erosion); andSettlements (Houses, Fishermen and Business).Potential Environmental Impacts (PEIs): Physical Environment (Air, Noise, Topography andLandscape, Soil, Water Bodies, Ground Water, Hydrology and Flooding, River Erosion andSedimentation, Landuse, Agriculture); Ecological Environment (Hilsa Migration, Wildlife,Vegetation); and Socio-economic Environment (Establishments including Graveyards, Bazars,Madrassahs, Schools, Mosque, Communities, Water Supply and Sanitation, Socio-economicStatus, Accidents, Health and Safety).57. Estimated environmental management cost had been US$ 6.8 million.58. The ADB study had recommended the following actions: Obtaining prior clearance under ECA, 1995 and ECR, 1997 Additional EA in case of changes during detailed design and additional work components; Sampling of River sediments during bridge construction; Arrangement of safe drinking water prior to construction work; Adequate training of concerned EA officials as per EMP; Developing environmental guidelines with focus on implementation of mitigation measures; Implementation of EMP and monitoring plan as per schedule; Creating a Wildlife Museum similar to that of Jamuna Multipurpose Bridge; Additional flood modeling during detailed design; Detailed study with employment of appropriate models for soil erosion downstream of Rivertraining structure; and1-21
