Stack Emissions Monitoring

The Integrated Pollution Prevention and Control (IPPC) requires industrial processes to regularly report their emissions to the atmosphere to the regulatory authority. These may be emitted via chimneystacks, ventilators or by other means. Accurate assessment of the various gaseous concentrations of these emissions requires the use of specialist monitoring equipment.

RPS can provide a full range of consultancy support, including MCerts accredited site visits to collect information and take emissions samples, processing of samples through our UKAS accredited facilities, and reporting upon the findings in a commercial and objective manner.

Our areas of expertise include:

Air Dispersion Modelling

Groundwater Monitoring

Nuisance Dust Assessments

Odour Monitoring

IPPC Applications and Improvement Conditions.

Case Studies

Nuisance Dust

Water stored below the surface forms the largest reservoir of available fresh water. The Environment Agency is responsible for ensuring the protection of these waters.

Dust consists of tiny solid particles carried by air currents. It is a problem for a wide range of manufacturing, domestic, and industrial activities. Construction, waste facilities, agriculture, and mining are among the industries that contribute to atmospheric dust levels.

The Environment Agency states that particles larger than 30 - 50 µm tend to be deposited quickly and as such are generally a nuisance. Settled particles may show up as a deposit on clean surfaces such as cars and window ledges. Deposited (nuisance) dust gives rise to the greatest number of complaints from residents in affected areas and without appropriate alleviation, residents can potentially be affected by dust up to 1km from the source (although concerns are most likely to be within 100 metres).

RPS has experience in undertaking nuisance dust projects. The work normally takes the form of an initial baseline survey and then surveying during and after a project has been completed in order to indicate whether activities result in an increase in the levels of nuisance dust.

Odour Monitoring

The generation and control of offensive odours from industrial facilities is a key concern for regulators, developers and local residents. RPS has a phased approach to odour investigations to ensure problems are clearly understood and solutions are developed to address the root cause(s) of odorous emissions.

The phases are:

Assessment of odour issues- identification and risk assessment of odour sources, compliant history and process evaluation.

Quantification of odour sources- odour sampling for olfactometry using a dilution procedure, MCERTS accredited chemical constituent analysis and sensory community questionnaires.

Odour impact assessment- modelling of measured odour emissions using recognised Gaussian dispersion models.

Solution development- to develop practical effective solutions including control technology review and preparing Odour Management Plans (OMP).

Albania

RPS supported an Oil Company based in Albania looking to expand operations on the Patos-Marinze Oil Field, the largest on-shore oilfield in Europe. To secure the funding necessary, the client was required to produce an Environmental and Social Action Plan (ESAP).

There were five distinct points to the ESAP which were to:

Perform an air quality baseline assessment

Carry out an air emissions control assessment

Perform an air quality assessment and emissions dispersion modeling

Develop an air monitoring programme

Develop routine workplace monitoring of air quality and noise


Working alongside the RPS’ Planners, an initial assessment of the point source releases on the oilfield was made. From this assessment a strategy for sampling  air quality and point sources, and the subsequent dispersion modeling, was developed and agreed with the client.

Point source sampling was carried out from a representative number of landfill gas engines, diesel engines, oil heaters and storage tanks for a broad range of pollutants, with air quality sampling undertaken during similar periods. The data from both surveys were used to feed into dispersion models and produce an air impact assessment. Ultimately the project was able to successfully address points 1-4 of the ESAP.
