Heggies conducted an Air Quality Impact Assessment of the proposed HUB Resource Reprocessing Facility.
Heggies was commissioned to conduct an Air Quality/Odour Impact Assessment of construction and operational activities associated with the proposed HUB Regional Resource Reprocessing Facility, near Orange, New South Wales.The scope of the air quality assessment was to identify existing air quality characteristics, establish suitable air quality management controls and determine the likely impact of the HUB Facility on local air quality, including both particulate matter and odour.Three scenarios were modelled to reflect different stages of the proposed operation, and to assess the potential impacts of both particulate matter and odour. Each stage took into consideration the location of the active landfill face, the internal haul route used to transport material to the face and the location of individual items of plant and equipment. For odour scenarios, the operation of the biofilter, leachate ponds and the quantity of putrescible material directed to landfill were additionally taken into account. Modelling of fugitive dust, PM10, and odour emissions was undertaken using the Ausplume Gaussian Plume Dispersion Model software developed by the Victorian EPA. Meteorological inputs were derived using the TAPM dispersion model.The output for all modelling scenarios were tabulated and presented graphically using concentration contours, indicating the air quality impacts upon the residential receivers. The facility was also assessed for greenhouse gas emissions.
