Table 7.2: Environmental and Social Management Plan Potential Impact Mitigation Measures Implementation Schedule Monitoring Indicators Monitoring Responsibility Frequency Cost Estimate (US$) Supervision CONSTRUCTION PHASE IMPACTS Soil Erosion Possible increase in soil erosion as a result of the construction activities (clearing of vegetation and soil excavation) Loss of productive topsoil resulting from soil excavation Soil contamination resulting from the release of chemicals (lubricant, fuel, paint) from the machineries Re-vegetate the construction site by planting rapidly growing vegetation/plants Use excavated soil for construction work Ensure immediate up of the area by removing the contaminated topsoil and disposing properly in a designated place During and the construction activities During construction During construction Erosion Soil Monitor erosion occurrence within and around the construction site Ensure that all the excavated soil are used for construction Monitor and document the contaminated soil disposal procedure consultant LAPU Weekly $500 Water Run-off erosion may occur from unprotected excavated areas during heavy rain resulting to sedimentation of nearby water-bodies Run-off erosion may occur from heaps of excavated soils during heavy rain resulting to sedimentation of nearby water-bodies Potential water pollution through run off of hazardous construction waste (lubricants, paint) Attend to any excavation area as quick as possible or create an embankment to avoid run off Create barrier for appropriate containment measures Proper disposal of construction waste During excavation activities During construction During construction Sediments Sediments metals Monitor BOD, Nitrate, pH, Heavy metals of the nearby water bodies before the construction and thereafter weekly during the construction activities consultant LAPU Weekly $3,000
Air Particulate matters emission from excavation and construction activities Potential emission of pollutants from the construction machineries (NOx, SOx, CO, THC) Spray water periodically to control dust Limit the vehicles allowed into the site and use efficient machineries During excavation and construction activities During construction activities PM NOx, SOx, THC and CO Monitor PM, NOx, SOx, THC and CO in the surrounding air before the construction and thereafter hourly during the construction consultant LAPU Weekly $5,000 Noise Noise resulting from the construction works Equipment (e.g. cement-sand mixer machine) to be placed as far as possible from the sensitive area/ human settlement Construction staff to wear ear muffs During construction activities Noise Monitor staff compliance to the use of ear muffs/plugs consultant LAPU Daily $400 Flora and Fauna Destruction of vegetation, loss of habitat and biodiversity Possible loss of endangered and rare specie Change in land use and disturbance of ecosystem Re-vegetate the construction site by planting rapidly growing vegetation/plants During and construction Vegetation Monitor the process consultant LAPU Monthly $500 OPERATIONAL IMPACTS
Social Possible displacement of settlements and business. Possible loss of crops, properties, and sources of livelihood Possible disruption of vehicle movement pattern, leading to traffic congestion Relocate the affected people in accordance with appropriate regulations Bank OP/BP.4.12:Involuntary Resettlement Policy) Provide alternative route for traffic Before Construction Before construction begins Complaints from the affected people Road traffic Document relocation procedures Monitor the road traffic before and during construction activities Contractor/ supervising consultant LAP Soil Contamination of soil as a result of waste (chemical, solid waste) disposal Pre-treat waste before disposal (through neutralization, thermal pretreatment, oxidation, etc) Before disposal pH, BOD,COD, Nitrate etc (based on the type of chemical waste generated) Monitor the surrounding soil pH, BOD,COD, Nitrate etc (based on the type of chemical waste generated). Monitoring to be before construction and monthly during the construction Respective institution's supervisors Respective institution's LAPU Monthly $500 Water Depletion of water resources Contamination of surrounding water bodies through improper disposal of waste water Possible run off from the temporary solid waste storage site into the drainage system and recycle water, also minimize water usage Install water flow meter Pre-treat waste water before disposal (through neutralization, thermal pretreatment, oxidation, etc) Avoid siting temporary solid waste storage close to drainage system or water ways. Dispose waste as soon as possible to avoid leachate generation Ensure proper containment of the During operation Before waste water disposal During site selection Implement mitigation measures through the operation phase Increase in utility payment. Increase in water flow meter reading pH, BOD,COD, Nitrate etc (based on the type of chemical waste generated) Monitoring the water flow meter Monitor the surrounding water bodies pH, BOD,COD, Nitrate etc (based on the type of chemical waste generated). Monitoring to be before construction and monthly during the construction Respective institution's LAP II-SIU Respective institution's LAPU Monthly $500
temporary waste storage site Air Possible release of microorganism to the air Ensure appropriate procedures are observed in the laboratories (e.g. International Best Practice in Safety of Research Laboratories) Implement mitigation measures through the operation phase Respective institution's supervisors Respective institution's LAPU Weekly Noise Construction activity will involve use of equipment that are expected to generate noise Install sound proof at the areas where the noise can not be reduced or mitigated to limit the noise to these areas. Ensure staff at these areas are adequately protected with ear muffs/plugs Ensure that efficient equipment are used Implement mitigation measures through the operation Noise Monitor noise level daily to ensure that it does not exceed the national acceptable limit Respective institution's PPT Respective institution's LAPU Daily Social Increase in construction workforce to the area Increase in employment rate (Skilled and unskilled Increase the infrastructure in the area to accommodate the population During construction and operational phases Respective institution public relation officer Respective institution's LAPU
