This Technical Guidance Note (TGN) on sampling requirements for monitoring stackemissions to air is one of a series providing guidance to our staff, monitoring contractors, industry and other parties interested in stack-emission monitoring. It is also a key reference document in support of our Monitoring Certification Scheme (MCERTS) and Operator Monitoring Assessment (OMA).
It provides guidance on:
    • the selection of the sampling position, sampling plane and sampling points;
    • access, facilities and services required;
    • safety considerations.
Throughout the document, references to sampling from stacks should be interpreted as also meaning sampling from vents, ducts and flues, unless otherwise stated. The section on safety draws attention to the importance of health and safety in stack emission monitoring, provides guidance on the hazards and risks associated with stack-emission monitoring and highlights the relevant health and safety legislation.

The TGN is divided into four chapters. Chapter 1 describes the main monitoring approaches, the fundamental principles of sampling and the importance of a monitoring strategy. Chapters 2 and 3 give guidance on the sampling requirements for periodic stack-emissions measurements and continuous emissions monitoring systems, respectively. Chapter 4 provides guidance on sampling facilities and safety
requirements for stack-emission monitoring.
