45. Final cover and revegetation: The final cover material for a sanitary landfill site must consist of earth and be at least 60 centimetres thick. However, if the thickness of each layer of solid waste is 6 metres or more, the final cover material must consist of at least 120 centimetres of earth. The landfill area must always be levelled following a minimum slope of 2 % and not exceeding 30 %.
All holes, cave-ins and faults must be filled in or repaired until the ground has stabilized. The operator of the sanitary landfill site must seed the soil and take all measures required in order that vegetation is still growing 2 years after the final cover.
