A Compliance Investigation (CI) is opened by the EPA when further information and/or action is required in relation to a compliance issue at a licensed site.  Under the CI, we can direct the licensee to provide additional information about the issue and to take specified corrective and preventative actions to restore compliance with the licence.  

When opening a CI, the EPA inspector assigns a risk rating (Low, Medium or Highdepending on the risk to the environment posed by the compliance issue. We consider the degree of risk when setting out timescales for the licensee to implement corrective actions.  

The CI remains open until the licensee provides us with clear evidence demonstrating that they have completed the required improvements and achieved compliance.  

The chart below provides details of Compliance Investigations from January to September 2021. 

The EPA maintains oversight of the licensee’s progress in resolving each CI. Unsatisfactory progress in resolving the issue may itself result in the escalation of enforcement action by the Agency. 

CIs in the National Priority Sites scoring system 

Compliance Investigations are used as an indicator in the National Priority Sites scoring system.  The system allocates increasing scores for higher risk rating (Low to High). 

A licenced site with an open CI is at risk of being included on our list of National Priority Sites 

See further details of the NPS scoring system.
