Observations of compliance performance emission tests are an important part of any air pollution enforcement
program. Data obtained during these tests are used to determine compliance with regulatory standards or to
determine baseline operating conditions for a source. We present the basic principles of STO and the fundamentals
of source testing methods, including Method 5, sampling train and procedures. We also discuss sample recovery
observations, procedural inspections, calculations, report writing and QA techniques. Students will participate in a
Method 5 sampling train "mock inspection" and receive hands-on training. SITE VISIT RECOMMENDED.
