This manual has been assembled with the most current information available at the time of this edition. Should EPA regulations change after a technician becomes certified, it is the responsibility of the technician to comply with any future changes. The EPA also reserves the right to modify the test questions and or call for a new certification based on advancements in future technology. The ESCO Institute will update this manual as necessary to keep current with EPA rulings.
