Compliance Assurance Associates, Inc. (CAA) provides a complete visible emission evaluator training and certification program (aka smoke school or opacity training) in accordance with 40 CFR 60 Appendix A, Method 9, Method 22, 203A, 203B, 203C. CAA trains your employees to properly determine and document compliance to visible emission requirements. CAA's philosophy is simple - we want our students to fully understand the concepts behind visible emissions observations and certification testing. By teaching the concepts, the certification process is made easy, and the observations definitive and defensible.
