Performance Evidence

A person demonstrating competency in this unit must satisfy the requirements of the elements, performance criteria, foundation skills and range of conditions of this unit.

The person must also cover waste at a landfill site on two separate occasions.

While conducting waste covering activities, the person must:

conduct an assessment of the landfill cell to correctly identify:

accessibility due to weather or ground conditions

cover material requirements for batter and stage of landfill development

prepare for the plant operation by interpreting work specifications and organising the required equipment, materials and personnel

follow organisational procedures to work safely and comply with regulatory and legal requirements

follow manufacturer specifications to:

conduct pre-operational checks of the plant and associated equipment to confirm correct function and operation, including:

pre-start visual checks, as specified in the range of conditions

service checks, as specified in the range of conditions

clean the plant and associated equipment

start-up, shut-down and isolate the plant

identify waste contaminants and non-conformances

use industry-approved techniques to cover and create a batter ensuring:

an even, smooth and tight cover is placed over the waste batter

erosion is minimised

correct depth and thickness.


Knowledge Evidence

A person demonstrating competency in this unit must demonstrate knowledge of:

classifications of waste

equipment and materials which may be required to operate, clean and maintain plant for waste covering

hazards and risks associated with waste covering

key features of the waste management hierarchy

organisational policies and procedures and regulatory and legal requirements relating to covering waste

procedures used to start-up, shut-down, isolate, maintain and clean plant used for waste covering

techniques used to cover waste in a landfill cell to maintain the batter and minimise erosion
