Description
This unit covers the rehabilitation of an exploration sites in the drilling and metalliferous mining industry industries. It includes: preparing for and rehabilitating exploration sites; capping drill holes; and rehabilitating access tracks.
Notes
Elements and Performance Criteria
1. Prepare for site rehabilitation
  • 1.1. Access, interpret and apply compliance documentation relevant to the rehabilitation of an exploration sites
  • 1.2. Access, interpret and apply the rehabilitation plan and Environmental Work Procedures (EWP)
  • 1.3. Identify, address and report potential hazards and risks
  • 1.4. Select and wear appropriate personal protective equipment
  • 1.5. Obtain map of area and identify location of sites to be rehabilitated
  • 1.6. Establish communication system and protocols
  • 1.7. Carry out rehabilitation plant and equipment pre-start checks
2. Rehabilitate exploration site
  • 2.1. Assess hydrocarbon spills at drill site and deal with according to legislation, environmental policies and procedures and company requirements
  • 2.2. Ensure saline or contaminated water sumps are completely dry
  • 2.3. Push waste materials resulting from exploration operations into sumps, and back fill, compact and cover with topsoil
  • 2.4. Operate plant and machinery, following EWPs, to scarify all cleared areas
  • 2.5. Retrieve cleared vegetation and put back onto rehabilitated site
  • 2.6. Remove and dispose of all rubbish
  • 2.7. Re-vegetate area if required under the rehabilitation plan
  • 2.8. Record rehabilitation details
  • 2.9. Inspect rehabilitated site for compliance with environmental and legislative requirements and safe entry
3. Cap drill holes
  • 3.1. Excavate hole collar to suitable depth
  • 3.2. Pour excess drill chips into drill hole
  • 3.3. Select and insert appropriate hole plug firmly into hole opening or collar, such that water ingress and future erosion is prevented
  • 3.4. Backfill excavated soil onto plug and compact firmly ensuring that sufficient compacted soil is left on hole to allow for subsidence and encourage run off
  • 3.5. Peg hole site and mark with ID number
4. Rehabilitate access tracks
  • 4.1. Remove all windrows
  • 4.2. Scarify tracks
  • 4.3. Retrieve as much as possible cleared vegetation and restore to access track
  • 4.4. Block or disguise the entrance to the track with any available materials

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit
The evidence required to demonstrate competency in this unit must be relevant to worksite operations and satisfy all of the requirements of the performance criteria, required skills and knowledge and the range statement of this unit and include evidence of the following:
knowledge of the requirements, procedures and instructions for rehabilitating exploration sites
implementation of requirements, procedures and techniques for the safe, effective and efficient completion of the rehabilitation of exploration sites
working with others to undertake and complete the rehabilitation of exploration sites that meet all of the required outcomes
consistent timely completion of the rehabilitation of exploration sites that safely, effectively and efficiently meets the required outcomes
Context of and specific resources for assessment
This unit must be assessed in the context of the work environment. Where personal safety or environmental damage are limiting factors, assessment may occur in a simulated environment provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills.
The assessment environment should not disadvantage the participant. For example, language, literacy and numeracy demands of assessment should not be greater than those required on the job.
Customisation of assessment and delivery environment to sensitively accommodate cultural diversity.
Aboriginal people and other people from a non English speaking background may have second language issues.
Assessment of this competency requires typical resources normally used in the work environment. Selection and use of resources for particular worksites may differ due to site circumstances.
Where applicable, physical resources should include equipment modified for people with disabilities.
Access must be provided to appropriate learning and/or assessment support when required.
Method of assessment
This unit may be assessed in a holistic way with other units of competency. The assessment strategy for this unit must verify required knowledge and skill and practical application using more than one of the following assessment methods:
written and/or oral assessment of the candidate's required knowledge
observed, documented and/or first hand testimonial evidence of the candidate's:
implementation of appropriate requirement, procedures and techniques for the safe, effective and efficient achievement of required outcomes
consistently achieving the required outcomes
first hand testimonial evidence of the candidate's:
working with others to undertake and complete the rehabilitation of exploration sites
