EES Scoping Requirements

Evaluation objective Key Legislation Amenity: To minimise adverse air quality, noise or vibration effects on the amenity of nearby residents and local communities, as far as practicable, especially during the construction phase Environment Protection Act 1970, State Environment Protection Policies and guidelines, Planning and Environment Act 1987, Transport Integration Act 2010

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

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

Model Predictions

• Arden Precinct
• Maximum 24-hour

average PM10 concentrations (µg/m3) including background of 21 µg/m3

• Criteria = 50 µg/m3

Air Quality

Model Predictions

• Domain Precinct
• Maximum 24-hour

average PM10 concentrations (µg/m3) including background of 21 µg/m3

• Criteria = 50 µg/m3

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

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

• Recommendation from Conclave is that EPR AQ1 is more

prescriptive in terms of the specific management measures.
