Prior to the commencement of the expansion project, authorisation is required on the basis of an environmental impact assessment (EIA) report. On request of the Ministry of Environment and Tourism (MET): Directorate of Environmental Affairs (DEA), the draft EIA regulations (April 2009) have been used as a guideline for this EIA process and report. To supplement this, reference has also been made to the Namibian Environmental Assessment Policy (1995).
