Emissions sampling services
Combustion stacks typically need to be sampled for only Particulate Matter, Sulphur Dioxide (SO2), and Oxides of Nitrogen (NOx) but process stacks require a wide variety of pollutants to be sampled. Yellow Tree can sample for all of the pollutants that are required by the South African legislation – including Dioxins/Furans (PCDDs and PCDFs) and Polycyclic Aromatic Hydrocarbons (PAHs). Few stack sampling companies can sample such a diverse range of pollutants. We have developed a relationship with a world-class European laboratory to make this possible.
Stack emissions testing is a legal requirement for many industries in South Africa according to the Listed Activities and Controlled Emitters legislation. Click to learn more.
The National Ambient Air Quality Standards (NAAQS) identify certain pollutants, such as benzene, toluene, ethylbenzene, and xylene (BTEX) that pose a threat to human health. These are monitored at the fenceline.
Leak Detection and Repair (LDAR) Programme and Monitoring
Section 21 of the National Environmental Management: Air Quality Act (NEMAQA) requires the petro-chemical industry, amongst others, to develop LDAR programmes and then to conduct subsequent LDAR monitoring.
Consolidated Emissions Results
With our multiple testing teams and short lead times, we can conduct testing at all of your sites nationwide and provide consolidated feedback to head office. Our reports are comprehensive and simple to understand, even for non-technical people.
The Bridge Between You and Law
We know the legislation well. We will sit with you and share how the legislation applies to your site. We can assist you with your Atmospheric Emissions License (AEL), NAIES and Annual Reporting. And we can help you build a relationship of trust with your Air Quality Officer as we have worked with many of the AQO’s in SA.
