CleanAir has added links for cross reference and equipment to EPA Emission Test and Stack Testing methods to make them much more convenient to use for Stack Testers. We have also corrected some of the glaring errors that were published in the Federal Register. We try to keep them up to date and welcome any suggestions to improve. However, if you want to read the unlinked EPA versions they are at the USA EPA Emission Measurement Center.
