Air Stack Testing Services
Federal and state regulations require industrial sources to maintain ambient and regional air quality standards by obtaining air permits and installing and maintaining pollution control equipment. Air stack testing is an important tool used to determine a facility’s compliance with regulatory air emission limits and permit requirements.
An air stack test, also known as emission test, source test, compliance test, and performance test, is a procedure for sampling emissions from a stack, process equipment, pollution control device, or other emission point. Air stack tests are used to identify specific regulated pollutant(s) and to determine pollutant emission rates and concentrations, and/or to demonstrate the capture, destruction or removal efficiency of pollution control devices. 
Air stack tests must be conducted while equipment is operating at the highest emission or pollutant value output, unless required differently by a permit condition or enforcement action.
In most cases, an air stack test is comprised of three (3) sampling runs with specified sample collection duration times. However, permit conditions and enforcement actions may require altered sampling parameters. Each air stack test, for each pollutant, must be performed using EPA or state approved sampling and analytical methods.
