Guideline: Continuous Emission Monitoring System (CEMS) Code

For monitoring systems for stationary source air emissions.
Last updated: 19 May 2023

This Continuous Emission Monitoring System (CEMS) Code (the CEMS Code) establishes requirements for the design, installation, performance, maintenance, and verification of continuous emission monitoring systems for stationary air sources.

Works approvals and licences granted by the Department of Water and Environmental Regulation under Division 3, Part V of the Environmental Protection Act 1986 may require continuous emissions monitoring on a stationary source. The CEMS Code identifies acceptable methods and specifications for the installation and operation of such monitoring systems.
