Smoke School Lecture Course
EPA Method 22 was established in 1982 and is a test method for determining the frequency of emissions from fugitive sources and from flares. It is not an alternative method to EPA Method 9. Instead of determining the opacity of emissions, Method 22 determines the frequency of emissions.
A source's air permit will usually indicate if a Method 22 test is required.EPA Method 22 may be used for the following applications:
Unlike Method 9, there is no certification requirement for Method 22. However, it is strongly recommended that you are familiar with visible emissions observations by completing a lecture course for Method 9 and at least one smoke school.
