Padma Multipurpose Bridge Project

field visits, sampling and environmental monitoring including but not limited to thefollowing:i. Physical Resources:o Topography, climate, soils, geology, landuse, aquatic resources, andsurface and groundwater resources.ii. Environmental Risks:o Cyclones, tornadoes, draughts, floods, earthquakes, road accidents, etc.iii. Ecological Resources:o Landscape and natural ecosystem, flora and fauna, wildlife and wetlandhabitats, and Protected areasiv. Environmental Quality:o Air (SPM, CO, NO x , SO x , Pb, etc.): Air samples should be collected fromRTW and approaches at Mawa and Janjira to identify the baseline and airquality in the project area.o Noise quality: Noise level should be measured along the approach roads,Ferry Ghats, resettlement sites, Service Areas and Construction Yardsduring day and night times to identify the baseline and present noise level inthe project area.o Groundwater quality (pH, Mn, Fe, As, EC, NH 3 -N 2 , Total hardness asCaCO 3 , Coliforms, Chlorine as Cl-): Samples should be collected twiceduring dry and wet seasons (to see seasonal variations) from resettlementsites, Service Areas, Construction Yards and Approach at Janjira Site.Samples should be tested for baseline setup and identifying the presentstatus of groundwater for drinking purpose.o Surface Water Quality (pH, BOD, Chlorine as Cl-, COD, TDS, TSS, DO,EC, Fe, As, Coliforms, NH3-N2, and oil and grease): Samples should becollected twice during dry and wet seasons (to see seasonal variations)from Padma River, Naodoba Channel at Janjira, Resettlement Sites,Service Areas and Construction Yards. Samples should be tested forbaseline setup and identifying the quality of the surface water.o River-bed Dredged materials: (Zn, Cu, Hg, Mn, Pb, Cd, Cr, As, and Se)Samples should be collected from the dredged sites at a reasonable depth.Samples should be tested for identifying the baseline chemical properties ofthe dredged materials and the suitability of the material to be used for roadembankment, bridge-end-facilities, service area, resettlement sites etc.v. Cultural Resources sites:o Structures or sites those are of historical, religious, or architecturalsignificancevi. Charland in Upstream and Downstreamo Detailed investigation on Charland in upstream and downstream in terms offlooding, fisheries, agriculture production, etc.5.2 Detailed Field Investigation to Screen Environmental Impacts5.2.1 Field Investigation and Analysis of Results9. Preparation of layout plan of environmental parameters and components of PMBconsisting of, but not limited to, the following information:o Bridge and approach road alignmentso River training workso Sampling location for environmental parameters (air, noise, water, anddredged materials)o Construction camp including storage of petroleum products and explosiveso Concrete, asphalt and batch mixing plantso Construction sites and campso Sand mining, quarry sites, and borrow pitso Water sourceso Waste disposal siteso Environmentally sensitive areasA1-20
