Emissions Measurement Center

The Emission Measurement Center (EMC) provides information on test methods for measuring pollutants from smokestacks and other industrial sources. This site compiles the test methods available for emission measurement, and EMC staff provide technical assistance in the use and application of the methods. For information on a specific test method or performance specification (method text, relevant documents, and frequently asked questions), use the pull-down menus below. For other information available on this site, use the links in the left margin of this page.
