EPA recently released a revised version of its Part 75 Emissions Monitoring Policy Manual. The revised manual is intended to reflect the 2002 revisions to Part 75 and includes new recertification and diagnostic testing guidance and modified guidance concerning add-on controls. In light of the official release of EPA's long anticipated recertification and diagnostic testing guidance, sources are advised to modify their QA plans given the new "requirements." A copy of the revised Policy Manual is available from our FTP Library.
