Description
This unit of competency describes the various maintenance functions carried out at a waste site.
Notes
Elements and Performance Criteria

2 Maintain access roads
  • 2.1 Maintain condition of roads to ensure public and personnel safety and maximise the efficiency of site operations2.2 Plan and carry out normal wear and damage repairs to minimise disruption to site operations2.3 Maintain effective drainage to maximise the removal of excess water2.4 Spread water to maintain a uniform wet surface to suppress dust
3 Maintain landfill cells
  • 3.1 Create ditches, bunds and slopes to prevent overland flow from entering exposed working face of cell, in accordance with company requirements and relevant legislation3.2 Maintain minimum coverage on landfill cell and batter covers in accordance with company requirements and relevant legislation3.3 Replace eroded cover and take preventative action to avoid further erosion
  • 3.4 Keep cover smooth and rounded to prevent pitting of surfaces and flooding3.5 Detect any vermin infestations and undertake pest management response in accordance with company requirements3.6 Trim, mow, clear or replace vegetation on landfill site, as appropriate, in accordance with company requirements3.7 Follow required company security procedures to prevent unauthorised scavenging
4 Maintain surroundings
  • 4.1 Clear drains regularly to prevent build-up of silt or blockages4.2 Clear fences, gates and barriers regularly to remove litter and debris and maintain a safe and clean environment4.3 Repair fences, gates and barriers as required to ensure integrity of form and prevent unauthorised entry to waste site or site areas4.4 Clear and clean signs of litter and debris to ensure full and clear visibility of all signage
5 Document maintenance activities

Potential job requirement risks and hazards
are those risks and hazards identified by the organisation that could lead to injury or illness of employees, contractors, visitors or the public; damage to plant, vehicles or property; or that could cause harm to the environment.
This relates to on-site and off-site activities (whether company owned or occupied premises, customer/client premises or public property) over which it could be expected the organisation had control.

Preventative action to avoid further erosion may include
drainage systems to prevent water erosion, planting grasses, ground covers, shrubs, tight compaction of cover, use of wind breaks and watering to prevent wind erosion.

Relevant legislation and codes cover state and federal
Australian Code for the Transport of Dangerous Goods by Road or Rail
duty of care
industry codes of conduct
occupational health and safety
Australian Standards
environmental protection legislation
road laws.

Safe operating procedures include
any activity or operation conducted on site to ensure health and safety of personnel/equipment in the area.

Waste site may include
landfill, materials recovery facility, processing plant, transfer station, treatment plant and waste generator's site.

Critical aspects of competency
Selection of appropriate emergency and personal protective equipment requirements.
Accurate identification of potential risks and hazards to maintenance activities.
Appropriate response to pest management.

OHS hierarchy of control.

Specific skills needed to achieve the performance criteria

To achieve the performance criteria, some complementary skills are required. These are:

following instructions, giving information
reading and interpreting schedules and work requirements
plant and equipment operation
covering and compacting roads
basic gardening (including lawn mowing, pruning and clearing)
maintaining landfill cell covers
using communications equipment (two-way radio and mobile phone)
hazard identification
record keeping
working in confined spaces
use of emergency and personal protective equipment
following MSDS
correct interpretation of job sheet and schedule
accurate determination of plant, equipment, tools, and materials requirements.

Other units of competency that could be assessed with this unit

This unit could be assessed on its own or in combination with other competencies relevant to the job function, for example:

PRMWM21B Cover waste
PRMCMN201A Participate in workplace safety arrangements
BSBCMN215B Participate in environmental work practices.

Resources required to assess this unit

The following resources should be available:

waste site for maintenance
maintenance materials and equipment
company maintenance policy
company environmental management policy
OHS requirements
personal protective equipment
site safety plan
MSDS.

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 customer/workplace interruptions and involvement in related activities normally experienced in the workplace.
Evidence of competency is best obtained by observing activities in this field and reviewing maintenance activities at a waste 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 the plan meets the objectives of the client and that it complies with industry expectations in the particular client environment. If the environment is narrowly defined or is not representative of industry needs, it may be necessary to refer to portfolio case studies of a variety of waste requirements to assess competency in maintenance activities.
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 audit, 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.
