Test Methods

This page lists some of the most common source test methods we use. We have extensive experience performing California Air Resources Board (CARB) test methods, Bay Area Air Quality Management District (BAAQMD) test methods, and EPA test methods. As a general rule of thumb, CARB test methods are accepted by all regulatory agencies within the state of California, BAAQMD test methods are accepted only by the BAAQMD, and EPA methods are accepted nationwide. If your source is mobile and you need to submit your test report to multiple agencies, the use of EPA test methods is recommended.

Analyzers

The following are continuous emissions monitoring test methods using gas analyzers. These methods provide real time data for the specified analyte.
