Management procedures
A range of routine measures will be used to manage and mitigate the effects of discharges of dust, odour or construction vehicle exhaust emissions during the Project. An adaptive approach to management of dust, including additional mitigation may be required in the event that: •
Monitoring indicates that abnormal discharges of dust are occurring;
•
Weather conditions are changing such that dust or odour discharges are more likely as determined using the Dust Risk Assessment; and / or
Complaints are received regarding discharges of dust, odour or construction vehicle exhaust emissions. If the available mitigation methods are unsuccessful in controlling discharges (i.e. dust and odour) that cause significant adverse effects on receptors beyond the Site boundary, the activities causing the discharge shall be suspended until adequate mitigation can be put in place.
•
5.1 Dust Risk Assessment To provide guidance to the Environmental and Sustainability Manager and area supervisors (refer Section 9 of this AQ DWP) on implementing dust mitigation, this Project will use a Dust Risk Assessment (DRA) approach. The DRA is described in Appendix C, and assigns a risk classification to each proposed activity with the potential to generate dust based on the scale of potential dust emissions and local environmental conditions (including sensitivity of adjacent activities and weather conditions). As the dust risk is dependent on local environmental conditions, the dust risk associated with activities should be re-calculated as conditions change. A “traffic light” indication of dust risk will be posted in each work area so that Project staff are aware of the dusk risk. The dust risk will be indicated as: • • •
Low risk (green). Moderate risk (orange). High or extreme risk (red).
5.2 Dust mitigation measures Dust management measures are specified for proposed enabling works activities in Table 5-1. Dust management measures may differ based on the dust risk of the activity calculated in accordance with the DRA in Appendix C. The control measures specified for the calculated dust risk level should be employed in addition to the measures for all preceding levels– e.g. a medium risk activity requires application of measures applicable to the corresponding low risk activity as well as measures specified for medium risk. Alternate methods may be employed after the effectiveness of those methods is demonstrated and this AQ DWP updated accordingly. The list of control methods is not exhaustive and additional methods may be found to be effective.
