Chad, Cameroon - Petroleum Development and Pipeline Project : environmental assessment
ESSO Exploration and Production Chad Inc. | Dames & Moore | COTCO/Esso Pipeline Company | Societe Nationale des Hydrocarbures
The Petroleum Development and Pipeline Project includes the oil field development in Chad, and a pipeline transportation system originating in Chad that traverses Cameroon. The environmental impact assessment covers both countries. Resettlement plans will be implemented for displacement of households from farm lands. The impacts on biological resources include removal of vegetative cover and shade canopy increasing soil surface temperature, decreasing moisture content, killing soil organisms and increasing potential for erosion in the oil field development and along the pipeline. A buffer zone will be set up to minimize the impacts. The project will also incorporate environmental measures to avoid potential disturbance to aquatic resources from oil spills. Induced access to undisturbed wooded savanna and riverine vegetation during construction and operation may lead to reduction of natural resources. This will be mitigated by controlling unauthorized use of pipeline route during construction. Increased peak flows and sediment loads of small tributaries of drainage will be corrected by draining surface runoff to more than one tributary. Disturbances to existing local supply wells caused by continuous withdrawal of project water supplies will be reduced by staggering project water supply wells. Reduced water quality caused from wastewater discharge will be corrected by treating sanitary wastewater in compliance with the World Bank effluent guidelines.
