On November 5, 2018, EPA issued a final rule that made corrections and updates to Test Methods, Performance Specifications, and Testing Regulations for Air Emission Sources. The revisions consist of corrections of typographical errors and technical errors in equations and diagrams, updates to procedures, and the addition of alternative methods that EPA has deemed acceptable to use. Testers and facilities are responsible for implementing any changes as applicable. To review the rule, see the link below:
