Secured Landfill or Hazardous Waste landfill is an engineered structure that is fully equipped with standards regulated components necessary to prevent any waste contaminants from polluting the environment and harming human health. As the landfill reaches its service life, the landfill is required to be closed and subjected to 30 years of post-closure care. An extensive post closure care period demands significant funding and resources to cover the cost of landfill aftercare. Aside from financial issue, post-closure care of hazardous waste landfill is emphasized to ensure maximum protection towards the environment and human health. In this case, reduction in post closure care period is believed to be a solution to the problem. Thus, this study aims to determine the completion criteria of post-closure care and investigates on the reduction of post closure care period in a hazardous waste landfill. The completion of the landfill post closure care was assessed based on three approaches which were impact/risk assessment approach, performance based approach and target values approach.
