Cheaper Solutions Put Value at Risk with Stack Testing
December 6, 2021

Gas emissions and pollutants such as smokestacks and vehicles are becoming a more significant public health issue than ever before. The EPA has mandated more stringent regulations to regulate harmful emissions in environmental conditions, resulting in a higher number of companies offering emission testing. But not all testing is created equal, and cheaper testing options often put data integrity at risk.
Many companies provide standard stack testing that reports on only emissions measured below a certain number. However, in certain situations, a facility may try to secure a permit for a particular emission. To do so, it can become quite costly with emission reduction credits. But if the facility chooses to run a dilution tunnel sampling, such as the OTM37 method, instead, they can measure concentration at least twenties times lower than a standard test can measure.
In many cases, a company cannot measure very low concentration with traditional methods, so they take other measures to demonstrate compliance. With OTM37, however, our team is able to measure that low and provide results from the beginning so companies are able to pass and receive permits changes.
For example, you may have a company that has a emission limit established that they have to achieve when they’re running. But as control technology improves, they have to start achieving lower and lower limits. The problem? Technology has not been able to keep up with those lower limits show that indeed the company is passing, until OTM37 came to market.
Additionally, OTM37 can provide an actual emission measurement rather than reporting that it’s not higher than a certain number. The cost of running OTM37 is much lower than purchasing credits, the data is reliable and accurate, and the reports show that a facility’s emissions will be much lower.
