Each year, the EPA receives a significant number of complaints from the public about licensed facilities by various means – telephone, writing, email, web etc. Once a complaint against a licensed facility is received, it is recorded and directed to the licensee by the EPA for investigation. At this stage, the EPA may also decide that it requires further investigation and open a Compliance Investigation with a specific set of Actions or Instructions for the licensee to carry out. The EPA may separately carry out its own monitoring and additional enforcement work may be necessary. If the complaints continue and/or if the licensee has not carried out the works required to rectify the problem, the EPA may take legal action against the licensee.

There was a 24% decrease in complaints received by the EPA in 2019 compared with 2018 and this is in keeping with an overall reduction in complaints over recent years as illustrated below:
