What is EPA Method 9?
EPA Method 9 is the federal reference method for quantifying visible emissions. The complete description of Method 9 can be found in Volume 40 of the Code of Federal Regulations, Part 60, Appendix A. You can also visit the EPA Website here.
Method 9 training is often referred to as “Smoke School” or “Opacity Certification”.
When you come to our Smoke School, you will learn to evaluate the opacity of visible emissions from 0-to-100% and how to correctly complete a Method 9 Visible Emissions Observation Form (VEO Form) for record. To become certified, you must evaluate to the nearest 5%, 25 plumes of White smoke and 25 plumes of Black smoke. No single error is to exceed 15% and you must pass the 25 White plumes and 25 Black plumes consecutively. Those wishing to remain certified in EPA Method 9 must pass the Field Certification test every six months. The classroom session should be attended about once every two years.
