2.9 Exploration, development and detailed design phase

2.9.1 General

At this exploration and design stage, there is usually a limited amount of activity that will generate significant emissions. Nevertheless, any drilling, excavation and handling or transport of materials that could potentially impact on neighbours should be conducted with that impact in mind. It may require the location or timing of various activities to be managed so that they have minimal impacts, and/or the watering of dusty operations that are close to sensitive areas.

As design detail progresses, there may be a need to refine emission control specifications based on improved inputs for modelling. Hence, it is important that the engagement with air quality consultants continues as required. Baseline monitoring, if any, should be in progress through this stage.

2.9.2 Risk assessment

Prior to any ground disturbance, a risk assessment of the operation should be carried out. An environmental specialist with particulate emissions experience should be involved to provide a sound understanding of the effects of any event being planned.

There are many cases in the mining industry where an incorrect understanding of the fundamental principles of particulate emissions formation has led to the creation of a particulate emissions problem and resulted in the mining operation’s having to expend disproportionate effort to resolve the problem. This kind of situation can be avoided when the risk assessment is carried out, if the risk assessment team contains the necessary skills.
