Pollution Incidents

Duty to notify of incidents

You must notify the NT EPA if you are undertaking an activity and an incident occurs which causes, or threatens to cause, pollution resulting in material or serious environmental harm. We call this a Section 14 Incident Report.

Notifying the NT EPA

You must notify us as soon as possible after the incident occurs.
You must notify us within 24 hours of becoming aware of the incident.

You can notify us in any of the following ways:



When reporting an incident you are to give us as much of the following information as you can:

  • what happened (the incident)
  • where the incident occurred
  • the date and time of the incident
  • how the pollution is occurring, or if it is not yet happening, how you think it may occur
  • the attempts being made to prevent, reduce, control, rectify or clean up the pollution and address any environmental harm
  • your identity. 



If you report the incident within 24 hours we can’t use the report as evidence to take legal action against you.

You do not have to make a report if the potential pollution or environmental harm is trivial or negligible, or if the incident results in only localised noise, smoke, dust, fumes or odour.

Generally you will need to make a report if there has been a spill of a contaminant or waste (such as hydrocarbons, paint, pesticides, or other toxic chemicals), and the spill:

  • has entered a waterway (including a drain)
  • spread more than 3 metres, or
  • left your premises. 



If you are unsure about making a report, contact us.

Pollution Incidents Reported

Section 14 Incident Reports are not confirmation of serious pollution events, rather they are notifications of pollution incidents that have potential to be more than trivial or negligible. These reports help keep us informed of all potential incidents across the NT and enable us to organise appropriate responses.
