Attenuation A general term used to indicate the reduction of noise or vibration, by whatever method or for whatever reason, and the amount in decibels, by which it is reduced.

Biodiversity Variety of all life forms on earth - the different plants, animals and micro-organisms and the ecosystems of which they are a part.

Carbon dioxide equivalent A metric measure used to compare the emissions from various greenhouse gases based upon their global warming potential (expressed as CO2-e).

Clean water Surface runoff from catchments undisturbed or relatively undisturbed by mining activities.

Consequence How much harm the impact could have, how many people in could affect and the duration of the harm.

Conservation significance Communities of conservation significance listed as critically endangered or endangered under the EPBC Act.

Contaminated water Surface runoff and underground mine water production which could potentially contain hydrocarbons, salts or other chemical contaminants.

Conveyor Mechanical handling equipment (which may include a belt, chain or shaker) used to move ore or other materials from one location to another.

Critical incident

An incident that:

Causes death or permanent injury to a person;

Incident requiring emergency medical response;

Involves an employee of company in the course of their employment;

Involves an employee of a Consultant or Subcontractor working on behalf of company;

Occurs at a place under the control of company, or a Subcontractor while engaged in activities related to the works; or
