The EPA has developed a system of performance-based indicators to rank industrial and waste licensed sites in order of priority for enforcement.  We use the National Priority Sites List to target our enforcement effort at the licensed operators with the poorest environmental performance. This helps us to drive improvements in environmental compliance. 

A score is assigned to each licensee based on the scores assigned to them, over the previous six months, under four key indicators of environmental performance and licence compliance: 

  • complaints 
  • incidents 
  • compliance investigations (CIs) 
  • non-compliances (NCs) with the licence

Higher scores indicate poorer compliance at a licensed site. 

The EPA updates the National Priority Sites list on a quarterly basis. 

See details about the NPS system and how the scores are allocated.

The EPA has developed a system to rank industrial and waste licensed sites in order of priority for enforcement. The National Priority Sites List will be used to target our enforcement effort at the poorest performing sites in order to drive improvements in environmental compliance.

A score is assigned to each facility based on enforcement factors such as complaints, incidents, compliance investigations (CIs), and non-compliances (NCs) with the licence.
