The Part 75 Emissions Monitoring Technical Q&A (formerly referred to as the Policy Manual) is a series of technical questions and answers (Q&As). These Q&As are intended to answer frequently asked questions and ensure that the monitoring requirements of 40 CFR part 75 (Part 75) are applied consistently. EPA will issue new or revised Q&As as they arise. If, after reviewing the regulations and these Q&As, you have additional questions, you should contact your Emission Monitoring Contact at EPA headquarters.
Please note that the information in these Q&As provides clarification only; it cannot create any rights enforceable by any party in litigation with the United States. EPA may decide to follow the clarification provided in this document, or to act at variance with this clarification, based on its analysis of the specific facts presented.You may need a PDF reader to view some of the files on this page.
