Elements and Performance Criteria

1. Organise for rehabilitation
   • Review environmental management and site development plans to clearly identify all job requirements
   • Identify and manage potential risks and hazards to job requirements, in accordance with company requirements, OHS, and other relevant legislation
   • Identify and obtain appropriate plant and equipment required for work in accordance with company requirements
   • Identify and obtain appropriate tools and materials required for work, in accordance with company requirements
   • Select and fit emergency and personal protective equipment in accordance with job requirements, manufacturers' specifications, company requirements and relevant legislation
   • Erect safety barriers and signage at work sites to ensure safety of surrounding personnel and public, in accordance with company requirements and relevant legislation
2. Recontour rehabilitation area
   • Ensure recontouring blends into the surrounding environment or as specified in the closure/rehabilitation plan
   • Minimise creation of dust using appropriate earthmoving techniques
   • Ensure final landform replicates surrounding environment or as specified by closure/rehabilitation plan and environmental guidelines
   • Determine catchment construction by site and weather conditions according to closure/rehabilitation plan and environmental guidelines
   • Carry out recontouring activities in accordance with closure/rehabilitation plan and environmental guidelines
3. Profile soil
   • Construct the soil profile in accordance with environmental guidelines, which are designed to stabilise contamination of materials and present contamination of soil and surrounding areas
   • Choose appropriate selection of materials for sub-soil, taking into account vegetation requirements
   • Ensure that construction of soil profile horizons emulate the surrounding environment or are in accordance with closure/rehabilitation plan
   • Check landform construction for completion prior to placement of final soil layer
   • Ensure that soil horizon construction follows land contour to reduce water flow down slope and increase water storage capabilities
   • Add nutrients to soil in accordance with closure/rehabilitation plan and environmental guidelines
4. Construct drains and berms
   • Peg and construct drain locations in appropriate locations and angles to ensure the control of water flow, in accordance with closure/rehabilitation plan
   • Place drain mechanisms at required dimensions and provide appropriate catchment locations for sediment in accordance with closure/rehabilitation plan
   • Construct berms to ensure water flows into designated areas in accordance with closure/rehabilitation plan
   • Control erosion of drain edges through the placement of appropriate drain mechanisms to reduce the speed of water flow
   • Reduce erosion by placing berms and intervals in accordance with closure/rehabilitation plan
5. Plant flora
   • Ensure planting activities are undertaken within appropriate season and growing conditions
   • Plant, protect and maintain seeds, ground covering, plants and trees in accordance with planting requirements and specifications
   • Apply fertiliser according to plant type, soil quality, manufacturers' specifications, company requirements and rehabilitation plan
   • Ensure planting arrangement conforms to contour of site and pattern specification as detailed in closure/rehabilitation plan
6. Document rehabilitation activities
   • Document all details of landfill site rehabilitation accurately and promptly in accordance with company requirements and relevant legislation

Other units of competency that could be assessed with this unit

This unit could be assessed on its own or in combination with other units relevant to the job function for example all the units covering landfill maintenance at a similar level may be able to be assessed in conjunction

Where assessment covering a cluster of units is to be conducted it may be useful to assess the units together as far as practicable This may be most useful when an experienced applicant is being assessed for the purpose of recognition of current competency

Resources required to assess this unit

The following resources should be available

company environmental management strategy

plant and equipment for rehabilitation

safety barriers and signage

materials for rehabilitation

PPE

OHS requirements

environmental protection legislative requirements

site safety plan

Gaining evidence to assess this unit

For valid and reliable assessment of this unit the competency should be demonstrated over a period of time and be observed by the assessor or assessment team working together to conduct the assessment The competency is to be demonstrated in a range of situations which may include customerworkplace interruptions and involvement in related activities normally experienced in the workplace

Evidence of competency is best obtained by observing activities in the field and reviewing the rehabilitation of a landfill site under normal industry operating conditions If this is not practicable observations in realistic simulated environments may be substituted

Consistency in performance

Assessment requires that strategies meet the objectives of clients and comply with industry expectations in the particular client environment If the environment is narrowly defined or is not representative of industry needs it will be necessary to assess the unit within a variety of waste management environments or different client needs to assess competency in the rehabilitation of a landfill site

Oral questioning or written assessment and hypothetical situations scenarios may be used to assess underpinning knowledge In assessment situations where the candidate is offered a preference between oral questioning and written assessment questions are to be identical

Supplementary evidence may be obtained from relevant authenticated correspondence from existing supervisors team leaders or specialist training staff

Note All practical demonstrations must adhere to the safety and environmental regulations relevant to each state or territory

Key competency levels

There are a number of processes that are learnt throughout work and life that are required in all jobs They are fundamental processes and generally transferable to other work functions Some of these are covered by the key competencies although others may be added
