My Class I operating permit requires Method 9 testing. What is a Method 9 test?
Many stationary sources discharge visible emissions into the atmosphere; these emissions are usually in the shape of a plume. A Method 9 test involves the determination of plume opacity. Opacity is the amount of light obscured by pollution. A person conducting a Method 9 must be certified. Method 9 can be found in 40 CFR Part 60 Appendix A.
