Stack Emissions Sampling
WHO NEEDS STACK SAMPLING?
In 2010 the very first list of activities was gazetted. It was passed under the National Environmental Management: Air Quality Act (NEMAQA) of 2004, and it was called “List of Activities which Result in Atmospheric Emissions which have or may have a Significant Detrimental Effect on the Environment.” This list of activities imposed limits on the concentration of pollutants that may be emitted from each industry. The list has been updated several times since, and today it regulates the following 69 industries within these 10 categories.

What Pollutants do we Measure??
The listed activities legislation stipulates pollutants that must be measured for each of the industries above. Yellow Tree is one of the few companies in South Africa that can measure all of the pollutants in the following table:
where do we operate?
Yellow Tree has offices in Cape Town, Jo’burg, and Durban and serves clients across the country and into Africa. The map beneath reveals that we are able to serve you anywhere in Southern Africa.
Why use Yellow Tree?
Is Yellow Tree the cheapest stack sampling company? No. But we represent great value. We operate with a slender single-digit profit margin, meaning that what you spend with us is spent where it matters: on the most accurate isokinetic machines and gas analysers; and on highly skilled Chemical Engineers who perform the measurements, calculations and reviews.
In addition, we avail ourselves to meet with you afterwards to answer questions and guide you towards compliance. All of this makes us more expensive than occupational hygiene companies that offer stack sampling as an add-on service. But one does not want to be penny-wise and pound foolish! The cost of non-compliance is far greater than the cost of accurate stack sampling and peace of mind that is offered by Yellow Tree.
