Elements and Performance Criteria

1. Review and evaluate landfill rehabilitation strategies to determine possible options
   • Review landfill rehabilitation strategies to determine all site development options, including catchment devices, drain and berm mechanisms to minimise erosion
   • Assess feasibility oflandfill rehabilitation strategies to ensure development of a realistic and achievable plan which conforms to client, OHS and relevant legislative requirements
   • Consult and involve client where appropriate in the development of a landfill rehabilitation plan with impacting environmental, legislative and OHS issues
2. Develop landfill rehabilitation plan
   • Consult local government authorities regarding the local provenance guidelines pertaining to the development of a landfill rehabilitation plan
   • Produce a landfill rehabilitation plan that fully addresses the construction of soil profile to ensure that the contaminated material is stabilised in accordance with OHS, legislative and environmental guidelines
   • Produce a landfill rehabilitation plan that details all aspects of implementation, including OHS, environmental and legislative requirements, process changes, education, resource requirements, timelines, schedules and targets
   • Ensure that landfill rehabilitation plan includes all aspects of client's environmental aims, where appropriate
3. Document plan
   • Document landfill rehabilitation plan in accordance with company requirements and relevant legislation
4. Present plan
   • Present landfill rehabilitation plan to client in businesslike manner, in accordance with company requirements using suitable aids where appropriate
   • Explain benefits, rationale and implementation of the landfill rehabilitation plan
   • Provide opportunities for client questions and discussion

Specific skills needed to achieve the performance criteria

To achieve the performance criteria some complementary skills are required These are

communication including liaison consultation facilitation conciliation report writing interpersonal giving information and presentation

reading and interpreting data and information

development of strategies

methodical organisation of work

brainstorming

feasibility analysis

prioritising

computer skills

report preparation

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 development of waste management plans and environmental policies 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

landfill rehabilitation assessment data

landfill rehabilitation strategy options

client requirements

relevant environmental protection legislative requirements

plan documentation tools eg computer wordprocessing software

case studies

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 development of a landfill rehabilitation plan 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 development of a landfill rehabilitation plan

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

Information below highlights how these processes are applied in this competency standard

	Perform the process			Perform and administer the process		Perform administer and design the process
How can communication of ideas and information be applied						Discuss strategies with relevant personnel
How can information be collected analysed and organised						Gather and analyse information from a number of sources including regulatory sources relevant personnel and company specifications
How are activities planned and organised						Develop landfill rehabilitation plan and organise presentation
How can teamwork be applied						Work cooperatively with colleagues to prepare the waste management plan and conduct a professional presentation
How can the use of mathematical ideas and techniques be applied						Conduct and document appropriate mathematical calculations
How can problemsolving skills be applied						Identify and solve risk elements in the landfill rehabilitation plan
How can the use of technology be applied						Demonstrate understanding of technological principles and physical skills to use appropriate equipment
