Air emissions sampling and analysis is a particularly difficult aspect of environmental monitoring and specialist equipment may need to be used. Both the sampling and analysis stages of air emissions monitoring require a high level of competency and quality control. There may be cases where the use of simpler techniques or measurement of surrogate parameters (i.e. measurement of a different parameter with a known relationship to the parameter under investigation) is justified, once this method is shown to be suitable, providing the required level of accuracy, precision and resolution.
Most licensees will not carry out their own emissions monitoring but will instead employ a contractor to carry out the monitoring and provide a report. The Agency generally supports the approach of using external specialist service providers and would not recommend that licensees attempt to carry out their own air emissions monitoring unless the relevant staff have been properly trained, appropriate and properly maintained and calibrated equipment is used, adequate procedures and quality control measures are in place and all relevant licence conditions are being fully complied with. Licensees must receive Agency approval (in advance) for the use of an in – house air monitoring team if the resulting is to be used to demonstrate licence compliance.
It is a mandatory requirement that all air emissions monitoring carried out to satisfy a licence requirement is performed by an accredited air monitoring contractor. It is important to ensure that both the sampling and analysis (where analysis is carried out subsequent to a sample being collected) is carried out by competent personnel. Accredited service providers are available for both emissions monitoring and laboratory analysis. Further information on the accreditation process for monitoring contractors can be found here. When employing accredited monitoring contractors or laboratory services it is important to check that the scope of accreditation covers the type of monitoring/analysis which is being sought.
Also, a licensee may choose to audit air monitoring service providers to review items such as personnel competency and training details, quality management systems, equipment maintenance and calibration records and standard operating procedures.
