Best Practice Guidance on Air Dispersion Modelling
PAEHolmes provided the Australian Aluminium industry with best practice guidance on the selection and application of models to simulate and predict the impact of air emissions. Our advice covered all aspect of modelling including model types, uncertainties and limitations and recommendations as to the suitability of each model to different applications. Using PAEHolmes' guide, the aluminium industry is able to achieve regulatory compliance in the best way possible. Their approach is now robust and secure against external critique by regulators, peer reviewers and key stakeholders.
We have also designed and implemented a series of best practice air quality modelling studies for the BHP Billiton Worsley Alumina Refinery in Western Australia.
Predictive Shemes for Dust Events
PAEHolmes developed predictive schemes that have enabled clients to accurately forecast dust events and be in a position to adapt their operations accordingly. These schemes have benefited relevant sites enormously as they are able to tailor their operations and take appropriate mitigating action whenever they have a firm view of an impending dust event.
Advanced Odour Characterization and Assessment Techniques
PAEHolmes developed methodologies and models for estimating odour emissions from operations such as poultry farms, cattle feedlots and piggeries. These best practice models and evaluation tools take into account farm management practices, shed designs, and meteorological factors enabling operators to determine effective separation distances, minimise odour emissions and optimise their productivity.
We have provided best practice advice to industry bodies including the Rural Industries Research and Development Corporation (RIRDC), Australian Pork Limited (APL) and Meat & Livestock Australia (MLA). We have also provided advice on the development of the “Odour Footprint Tool” to the University of Nebraska, USA including advice on emissions estimation, peak to mean factors, source representation and the influence of terrain on odour impacts.
NPI Emission Estimation Technique Manuals
PAEHolmes was instrumental in the development of the National Pollutant Inventory (NPI). We drafted the original Emission Estimation Technique (EET) manuals for many industries and have updated many since.
EET manuals are designed to assist organisations that have to report emissions of listed substances to the NPI each year. They describe procedures and recommended approaches for estimating emissions on a sector by sector basis.
Our expertise in emissions estimation and inventory development enables us to write these manuals and update them to ensure the best approach is adopted in each situation, so users can achieve compliance with ease and confidence.
