Site Visits

The EPA visits industrial and waste licensed facilities to assess compliance and overall environmental performance. The visits can involve monitoring of emissions to air, water, or noise, odour assessments, and/or an assessment of compliance with licence conditions. The EPA issues a report for each visit and these site visit reports are made available on the EPA’s website ( The Industrial Emissions Directive (IED) sets out a minimum standard for visiting facilities. The period between two site visits must be based on an assessment of environmental risks, and must not exceed one year for high risk sites and three years for low risk sites. Summary information for Site Visits completed during 2019 are provided in the table and charts below.
