A stack test measures the amount of a specific pollutant or pollutants being emitted through regulated stacks at facilities subject to the requirements of state and federal regulations and permit conditions. Stack testing is an important tool used to determine a facility's compliance with emission limits. Many companies hire contractors to conduct performance tests. KDHE maintains a list of contractors who are available for performance testing in Kansas as well as a List of Performance Testing Companies (PDF). The Environmental Protection Agency (EPA) also maintains a list of national performance testing companies; visit the Air Emission Measurement Center page to view said list.
In addition, KDHE provides Performance Testing Guidelines to help facilities and stack testing companies prepare protocols for, conduct, and prepare reports for performance tests in Kansas.
