Detailed environmental management plan for standard construction and good engineeringpractices. Environmental, Health and Safety Manager with Contractors’ Team.‣ Impact of Riverbed Dredged Materials: Analysis of the chemical properties of dredged materials Assessing the presence of toxic and heavy metals like As, Pb, Cd, Cr, Hg, Mn, Zn, etc. andmulti-residue Pesticides (carbamates, pyrtheods,organo-chloride, Organo-phosphate, Organonitrogen) Impact of such contaminants on end use and disposal of dredged spoil materials‣ State of Aquatic and Terrestrial Flora and Fauna Hilsa, dolphins, gharial Wildlife Avian species like migratory and local birds Vegetation, especially due to Tree cutting‣ Local Hydrology Impacts on local hydrology Erosion and siltation effects‣ Climate Change Assessment of climate change impact and associated risks to the project; and Identify other climate change mitigation measures for the various components (bridge, RTWand approach roads).‣ Associated and Induced Impact Impact assessment for associated project components (widening of Dhaka-Mawa road as partof the Asian Highway, railway network development, and bypass road in Group Bdevelopment area of Rajuk) and regional economic development due to the implementation ofthe project. A qualitative assessment will be made based on the available information.‣ Charland Study Investigation on Charland (sand bar) in upstream and downstream in terms of flooding,agricultural production, fisheries, high ecological significance as riparian habitat for migratorybirds, Water Supply, Sanitation and hygiene program etc.‣ Sand mine, Quarry, and Borrow Sites Impacts on ecological resources in the area associated with sand mining, quarry and borrowpit operations needed for construction.‣ Health and Safety Issues Workers’ safety Safety of inmates of the project area and visitors Provision of safe drinking water, proper sanitation facilities in construction yard, resettlementsites, and in the induced development area of the regional highway STD and HIV/AIDs‣ Tourism Development Development of infrastructural facilities to support tourism in the project area Designated landing areas in RTW for speedboats and Country boats to encourage tourists. Concept development for a proposed museum in Padma bridge site.‣ Environmental Risks Flood Earthquake Cyclone/Tornado Road Accident Terrorist threats/events Accidental Spills of chemicals Emergency Preparedness for HP Gasmain1.6 Key Additional Aspects for Consideration1.6.1 Addressing Rail Components62.
