Involuntary resettlement induced by river rehabilitation and embankment work is not expected. Survey method: Survey on existing conditions of floodwater reservoir, dam sites as well as their surrounding areas and sites for river rehabilitation and embankment works. Stakeholder meetings with local people. Most of the sites and the surrounding areas of floodwater reservoir, dam and locations where river rehabilitation and embankment work will be conducted are farmland. Survey method: Survey on land utilization at the sites of floodwater reservoir and buildings. No impact is expected on governmental offices, but the matter should be confirmed with governmental offices in each province, as the river basin is significantly wide. No impact is expected on schools and healthcare centers, but the matter should be confirmed with governmental offices in each province, as the river basin is significantly wide. The Luo tribe lives mainly in the downstream of the river basin, and the Kalenjin tribe lives in the upstream. However, governmental offices in each province should confirm the location of ethnic groups and low-income people, as the river basin is significantly wide. Same as item 9 It is assumed that there are no cultural heritages and properties, but the matter should be confirmed with governmental offices in each province, as the river basin is significantly wide. When implementing river rehabilitation and embankment work, conflict of interest may arise between left and right banks of the river. Mitigation measures: areful consideration during the planning stage. ommunication with local community leaders and other relevant parties. When planning dam construction, river rehabilitation or embankment works, adjustments regarding existing water rights in both small and large-scale plans should be considered. Survey method: Detailed survey of the local area during the planning stage and investigation of registers of water rights and other such documents. Percentage of HIV/IDS carriers is extremely high among workers engaged in the yen loan project, Sondu/Miriu Hydropower Project. Similar situation can be expected from other dam construction projects. Large-scale construction such as dam or floodwater reservoir can bring changes to topographical and geographical features. Mitigation measures: areful consideration during the planning stage (design of the dam, dam height, spillway position, restoration of raw stone mounds, establishment of management buildings and facilities, etc.). Water may leak to the ground around the floodwater reservoir. Survey method: Spring water survey of the ground around the floodwater reservoir during the planning stage. 8

Survey methods: Follow-up monitoring survey. Large amount of discharge sand may accumulate in dam, causing a decrease in the amount of sand supplied to the banks of Lake Victoria, which may eventually lead to erosion of the lake shore. Survey method: Follow-up monitoring survey. onstruction of dam and floodwater reservoir may have some impact on the reproduction and possibly extinction of species because of direct changes to habitat conditions. However, the extent of the impact is unclear. Survey method: Data collection from relevant documents and detailed survey of the local area during the planning stage. onstruction of the dam and floodwater reservoir may have regional impacts on weather conditions. Survey method: Follow-up monitoring survey. ir pollution may occur from dust produced during construction works and during transport of materials and equipments. Mitigation measures: Usual countermeasures for preventing dust, such as by spraying water during construction works, and by asphalting roads and spraying water to minimize dust from road transport. Water contamination may occur from construction works related to dam and raw stone mountain. Mitigation measure: ontaminated water treatment facility far downstream of the site. Waste soil may be produced by drilling work related to dam and raw stone mountain construction. Mitigation measure: Proactive prevention of waste soil for use as embankment material, backfilling material, and lean-mix aggregate. Noise and vibration may occur from works related to dam and raw stone mountain construction. Mitigation measure: When necessary, introduction of noise-free and vibration-free construction machinery. Large amount of soil and sand discharged from upstream may accumulate in the dam. Some amount of sediment is also expected to accumulate along the road rehabilitation segment. Survey method: Investigation of dam sand discharge methods during the planning stage. ccidents may occur during construction and other operations. Mitigation measure: Strict safety management during construction and operations. Overall rating () : Serious impact is expected, : Some impact is expected, : Extent of impact is unknown (Examination is needed. Impacts may become clear as study progresses.), No mark: No impact is expected. IEE/EI is not necessary. 9
