Licence conditions for pollution studies and reduction programs

Summary
 
Licence number: 5590
Title: Air Quality Impact Assessment 2023
Start date: 19 Jun 2023
 
Licence Condition
The licensee must engage a suitably qualified person to complete a comprehensive Air Quality Impact Assessment (AQIA) for Cadia Valley Operations in accordance with the Approved Methods for the Modelling and Assessment of Air Pollutants in NSW using the most recent information available. The AQIA must be completed and submitted to the EPA by 14 July 2023. The AQIA must include the following: a) All sources of particulate and metal emissions b) For each emission source, details of daily average and maximum operating parameters c) An emission inventory for all emission sources with supporting information or justification for all assumptions and, where available, based on actual emission data (eg. vent shaft testing) d) Emission rates (g/s and kg/yr) modelled including details on any hourly varying emission rates e) Details of controls used for each source and assumed control efficiencies used in modelling f) Use of site-specific meteorological data g) Include metal speciation from each source with supporting information h) Predicted incremental impacts for PM2.5, PM10, TSP, and individual metals for the current total Cadia operations i) Source apportionment analysis of the incremental impacts for PM2.5, PM10,TSP, and individual metals to identify the major contributors to offsite impacts (eg. a specific tailings dam or specific ventilation shaft) j) Sensitivity of predicted impacts to emissions estimates and meteorological variability k) Discussion on the meteorological conditions resulting in the offsite impacts for each source l) Evaluation of maximum extent of offsite impacts
