Stack Testing and Monitoring

EM – November 2022: This month, EM discusses fundamental concepts in stack testing, its methods, and applicable regulations; ambient air monitoring procedures; and new technologies.

Stack testing, also called performance testing or emissions performance testing, is a critical tool to determine compliance with U.S. Clean Air Act regulations, state regulations, and air permits, and to provide real-world data for emission inventories and air quality modeling. A wide variety of measurement methods and technologies are used in stack testing.

In the first article, “Introduction to Stack Testing” by Banks Miller, the author provides a primer on current stack testing regulations, methods, and technologies.

Next, in their article, “Establishing an Ambient Air Monitoring Network Utilizing the Data Quality Objective Process,” the authors, headed by Lynn E. Bisping, describe how the Data Quality Objective process plays an important role in defining the type, quality, and quantity of data needed to develop and implement adefensible ambient air monitoring program.

In the third article, the authors, headed by Saikat Ghosh, present a case study of “Stack Sampling of Radionuclide Emissions at a Well-Mixed Location for Regulatory Compliance”. In this article, the authors provide an overview of the regulatory requirements for sampling radionuclides from nuclear facility exhaust and the options for determining a well-mixed sample location.
