class criteria for each outlined construction activity. As demolition will not be undertaken during the construction phase, impacts associated with demolition have not been considered within the assessment.
Table A1. Criteria Used in the Determination of Dust EmissionMagnitude Activity
Small Earthworks Construction Trackout Total site area <2,500m2.
Total building volume <25,000m3.
<10 outward HDV trips in any one day.
Unpaved road length <50m.
Total site area 2,500 – 10,000m2.
Total building volume 25,000 – 100,000m3.
10-50 outward HDV trips in any one day.
Unpaved road length 50- 100m.
Criteria used to Determine Dust Emission Class Medium
Total site area >10,000m2.
Total building volume >100,000m3.
>50 outward HDV trips in any one day.
Unpaved road length >100m.
The potential dust emission magnitude for the proposed development site was determined using the criteria detailed in Table A1:
The dust magnitudes for earthworks, construction and trackout are summarised in Table A2.

20.1.4 Step 2B: Define the Sensitivity of the Area 10.
Large Large Large
The sensitivity of the area takes into account the following factors:
The specific sensitivities of receptors in the area; The proximity and number of receptors; The local background PM10 concentration; and
Site-specific factors, such as whether there are natural shelters, such as trees, to reduce the risk of windblown dust.
