Implement landfill rehabilitation plans

Assessment tool

Version 1.0
Issue Date: April 2024


This unit of competency specifies the outcomes required to rehabilitate a landfill site. The unit covers reviewing site development plans to identify rehabilitation requirements and organising required plant, equipment, materials and personnel. The unit also covers recontouring the area; constructing soil profiles, drains and berms; and using gardening methods to plant flora according to rehabilitation plans.

The unit supports those who work in lead roles in a waste management team.

No licensing, legislative, regulatory, or certification requirements apply to this unit of competency at the time of endorsement.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
