No further concern with environmental parameter EIA needed as described in IEE Comments: The Wainuri-Kirakira and Kirakira-Warihito Road already exists, does not traverse any primary forests, protected, ecologically sensitive or densely populated areas and will not create any conflicts in resource use or development. Of the 79 km of road to be included in the subproject 95% of the length will be covered by routine maintenance activities and construction of approximately 27 crossings. About 3.4 km will involve the rehabilitation of old logging roads and construction of some 890 m of new road (comprising five short sections) for bridge approaches. The proposed new crossings and approach roads are entirely located in areas already impacted by past land-use and logging. For three of these sections minor resettlement relating to land acquisition and loss of a maximum of two houses and areas of crops and trees will require the preparation of a short resettlement plan. Therefore, the recommendation is that this subproject should have an environmental categorization of Category B and does not require further investigation or a full EIA.
