We are aware of community concerns regarding dust (particulates) and odour within the local area and are proactively seeking to eliminate emissions from our Munster Plant through a range of actions, as outlined on our improvements page.
Throughout the past decade we have dramatically reduced our environmental footprint at Munster, particularly in relation to dust emissions from the stacks. Cockburn Cement has ceased clinker manufacture at Munster, with Kilns 3 and 4 currently in care and maintenance.
Our Kiln 5 and 6 stack emissions are heavily regulated by the Department of Environment Regulation via our Environmental Protection Act 1986 licence. Our extensive stack emission monitoring includes the use of Continuous Emissions Monitoring Systems (CEMS), quarterly stack monitoring and modelling.
Continuous Emissions Monitoring Systems (CEMS)
We operate a Continuous Emission Monitoring System (CEMS) as per our Environmental Protection Act 1986 licence. The CEMS provides, on a continuous basis, a permanent record of emissions from Kiln 5 and 6.
The CEMS monitors dust (opacity), sulphur dioxide and nitrogen oxides. The data is logged continuously to an environmental emissions database and reported to the Department of Environment Regulation on a monthly basis. The dust emissions data is displayed live on our Community Website and is available to the public at any time.
Independent, NATA Accredited Stack Monitoring and Modelling
Our stack emissions are heavily regulated by the Department of Environment Regulation via our Environmental Protection Act 1986 licence. As per our licence, an independent NATA accredited consultancy conducts quarterly stack monitoring on Kiln 5 and 6 for specific pollutants. This data is then used for modelling to determine the ground level concentration of the pollutants. Modelling is carried out using the Ausplume version 6.0 dispersion model. The model configuration is based on the configuration developed by our consultants and approved by the Department of Environment Regulation (formerly Department of Environment and Conservation). The ground level concentrations are compared to various state, national and international air quality standards and guidelines.
The results of the stack monitoring and modelling are reported to the Department of Environment Regulation quarterly.
