Stack Emissions Monitoring

Stack Emissions Monitoring ECL Banner

Stack Emissions Monitoring (also commonly referred to as Stack Emissions Testing and Air Emissions Testing) is often used to demonstrate compliance against limits outlined for permitted processes (including the Environmental Permitting Regulations (2010) and the Industrial Emissions Directive (2011)).

To comply with the Environmental Permitting Regulations, those who carry out most industrial processes are required to report any  emissions released into the atmosphere on a periodic basis.


What Is Stack Emissions Monitoring?

Stack Emission Monitoring is essentially the monitoring of air from an emission point. This type of monitoring is often carried out on  printer exhausts, thermal oxidisers and boiler stacks amongst others.

Stacks from industrial processes carry pollutants such as solvents, gases, dusts and particles. Local air quality can see a detrimental effect and for this reason such emissions are often regulated.

Air Emission Testing is a very important service used to determine a processes compliance within the regulated emission limits.


How Often Is Air Emissions Testing Required?

Regulation varies from process to process, however measurement of the concentration of such pollutants are required on a regular basis (Periodic stack emission monitoring). The regulator sets limits for the concentration whilst the monitoring will set out to determine whether the emissions are above or below these set limits.

Part A processors are regulated by the Environment Agency whilst lower emitting processors (Part B) are regulated by Local Authority. Individual requirements will be documented within each site’s permit. 

The schedule of this type of monitoring can range from quarterly to every three to four years dependant on permit regulations. Sometimes there will be a need for a process to be monitored continuously over a 24 hour period depending on the scale of emissions being emitted.


Who Can Monitor Such Emissions?

Part A processors can only be monitored by MCERTS accredited test houses such as ECL. For smaller Part B processors MCERTS accreditation is not a requirement however Local Authorities do recommend it due to the quality of service, in place management systems and proper training / experience required.

When emission levels exceed the set limits set by the regulator via permits or licences, a non-conformance would be issued and the regulator would need to see that every effort is being made to rectify this. This can be achieved via abatement such as scrubbers, thermal oxidisers, bag filters and/or cyclones depending on the nature of the pollutant. Another option would be to undertake Atmospheric Dispersion Modelling to ensure there is no detrimental effect on the local air (ambient air quality).

This is again where an experienced, fully qualified and accredited Air Emissions Testing company is beneficial.

Our Stack Emissions Monitoring Accreditations

Our Stack Emissions Testing team has project managed and delivered contracts for the Environment Agency, Scottish Environmental Protection Agency, and numerous Local Authorities.

ECL were the first company to develop a training course for Industrial Companies that covered the requirements of Operator Monitoring Assessment (OMA). This was supported by the Environment Agency and delivered with them for several years.

In addition to this, ECL were also one of the first companies in the to deliver specific BS EN 14181 Training courses and seminars in the UK.

In support to the MCERTS and UKAS accredited Stack Emissions Monitoring teams, our office based staff in Pontypridd, Wales and the West Midlands, England are able to provide technical support and statistical interpretation for all QAL2 (BS EN 14181) and routine monitoring undertaken.

ECL hold UKAS and MCERTS Accreditation for monitoring a vast range of pollutants. An outline of our schedule of accreditation can be viewed below:
