About these questions
Every question was written for this site and checked against the official rule text: EPA's Section 608 pages on epa.gov and 40 CFR Part 82, Subpart F on ecfr.gov. Each explanation links to the page or section it relies on. Real exams are written by EPA-approved certifying organizations from a question bank released only to them, so do not expect the same wording on test day.
Source for the test format: 40 CFR 82.161 and Appendix D to Subpart F.
