Stack emissions testing should be performed by a suitably qualified and experienced emissions testing provider using appropriate sampling methods, equipment and laboratory analysis. For regulated projects, the testing approach should meet the requirements of the applicable environmental licence, regulator and approved methods. Ektimo provides stack emissions testing and associated laboratory analysis for industrial facilities across Australia. 

Stack emissions testing measures pollutants released from an industrial stack, duct or other point source to determine analyte concentrations, mass emission rates and support environmental assessment or compliance requirements. Testing may be required under an environmental licence, during commissioning or process changes, for periodic compliance monitoring, or when requested by the relevant Australian environmental regulator.

Yes. Ektimo provides stack and source emissions testing to support environmental licence and regulatory requirements across Australia. The appropriate testing methods, pollutants, frequency and reporting requirements depend on the applicable environmental licence, jurisdiction, regulator and approved methods. Ektimo can help scope the testing requirements and provide the associated measurements, analysis and reporting.

Depending on the industrial process, environmental licence and applicable testing methods, stack emissions testing can measure pollutants including particulate matter, NOx, SO₂, CO, VOCs, metals and acid gases. Other pollutants may also be measured where relevant. The required analytes should be determined based on the facility’s processes, regulatory requirements and conditions of the applicable environmental licence.

Whether NATA-accredited testing is required depends on the applicable environmental licence, regulatory requirements, testing method and purpose of the testing. Where accredited testing is required, the relevant testing or laboratory activities should be covered by the provider’s NATA scope of accreditation. Ektimo can help determine the appropriate testing and analytical requirements for your project.

The required testing frequency depends on the facility’s environmental licence, regulatory requirements, emission limits, process and monitoring conditions. Some facilities may require periodic or annual testing, while others may have different requirements. The applicable licence and conditions set by the relevant Australian environmental regulator should be checked before establishing a testing schedule.

An emissions exceedance should be investigated promptly against the applicable environmental licence and regulatory requirements. The appropriate response may include verifying the result, investigating the cause, reviewing operating conditions and implementing corrective actions or additional monitoring. Reporting or notification requirements depend on the relevant Australian jurisdiction, regulator and environmental licence conditions.

Useful information includes facility and process details, stack or emission-point information, pollutants to be tested, environmental licence conditions, previous test results, applicable methods, operating conditions and proposed testing dates. Stack dimensions, sampling locations, site access arrangements and relevant safety requirements can also help the testing provider plan the project effectively.
