TRANSCO CLSG, a Regional Transmission Company set up under the West African Power Pool (WAPP), contracted INTEGEMS to undertake consulting services for the “Establishment of a Baseline Database of the Environmental Component of the CLSG Project Area in Sierra Leone”. INTEGEMS specifically undertook water quality monitoring of the specified watercourse crossed by the corridor of the transmission line; preliminary characterization of the soils, vegetation and wildlife of the project area; and air quality and noise level monitoring in the settlements of the Project area. The project also includes field data monitoring and collection; data management and laboratory analysis and mapping; development and deployment of a Web-based GIS mapping application and database to support TRANSCO in its mission to streamline baseline environmental data-flows and provide accurate, reliable and timely baseline environmental data and information to policy-makers and the public.
The total length of CLSG interconnection line is approximately 1,411km and the section in Sierra Leone is 530km. Although the line route is 530km long, the actual area affected by the transmission line project is relatively small. The project will be carried out within a Right of Way (RoW) of 40 m that will span seven districts namely, Pujehun, Kenema, Kono, Tonkolili, Koinadugu, Bombali, and Kambia for a distance of about 530km.
