EPA’s Air Emissions Monitoring Programme

In addition to the licensees own monitoring data, the EPA also carries out a programme of independent air emissions monitoring at licensed sites called the Air Emissions Monitoring Programme (AEMP). The purpose of this programme is to spot check the actual air emissions from stacks against the allowable emission limit values specified in the licence. This enables the EPA to not only check the reliability or otherwise of companies own emissions data, but to provide a level of public confidence in the management of industrial air emissions.

Each year sites are selected for monitoring using a risk based approach, with all sites generally being visited at least once in every three year period. The criteria used for site selection include the following:

  • The number of ELV breaches detected by EPA monitoring;
  • If any EPA compliance investigations have been initiated;
  • The number of ELV breaches reported by the licensee;
  • Whether dioxin monitoring is specified in the licence; and
  • The type of activity (i.e. power sector/priority site).

For the most part, visits are unannounced. Monitoring is carried out at 1 or 2 individual emission points at each site. In general, those selected are the most significant emission points or emission points which have had previous emission breaches as reported by either the licensee or through the independent EPA monitoring.
