Air Quality Impact Assessment Shane Lakmaker 1
Air Quality EES Scoping Requirements Evaluation objective Key Legislation Environment Protection Act Amenity: To minimise adverse air quality , 1970, State Environment noise or vibration effects on the amenity of Protection Policies and nearby residents and local communities, as far guidelines, Planning and as practicable, especially during the Environment Act 1987, Transport construction phase Integration Act 2010 2
Air Quality Environmental Risk Assessment Outcomes • Dust emissions from construction activities • Exhaust emissions from on-site plant and equipment • Emissions from construction traffic movements • Increased / concentrated traffic emissions due to road closures or diversions • Emissions from ventilation outlets • Odorous emissions from excavation, transport and disposal of soils and sediments 3

Air Quality Existing Air Quality • EPA measures air quality at 10 locations in the Port Phillip Air Quality Control Region; some results for Richmond are shown below Statistic from 2011 2012 2013 2014 Objective Richmond data Maximum 24 ‐ hour 42 47 42 63 50 average PM 10 (µg/m 3 ) Annual average PM 10 17 17 17 N/A ‐ (µg/m 3 ) 7
Air Quality Model Predictions • Arden Precinct • Maximum 24-hour average PM 10 concentrations (µg/m 3 ) including background of 21 µg/m 3 • Criteria = 50 µg/m 3 8
Air Quality Model Predictions • Domain Precinct • Maximum 24-hour average PM 10 concentrations (µg/m 3 ) including background of 21 µg/m 3 • Criteria = 50 µg/m 3 9
Air Quality Conclusions to the EES Technical Appendix H • Construction activities at Arden and Domain represent the highest risk • Concentrations of environmental indicators are predicted to comply with air quality objectives and goals • Compliance based on conventional dust mitigation practices • Operational impacts are expected to be minimal, consistent with monitoring in the vicinity of the existing network 10
Air Quality Conclave of Air Quality Experts 1. Robust and transparent framework 2. The Botanica apartments will be sensitive to increases in local dust 3. Design criteria from SEPP (AQM) for point sources 4. Dispersion modelling and adequate basis for defining residual risk 5. Respirable crystalline silica 6. Further dispersion modelling 7. Community Liaison Committee 11
Air Quality Environmental Performance Requirements • Recommendation from Conclave is that EPR AQ1 is more prescriptive in terms of the specific management measures. 12
