from <strong>the</strong> coal stockpiles, to just a few at Grasstree Beach, 8.25km from <strong>the</strong> coal stockpiles.Regrettably <strong>the</strong>re are no measurements available for McEwens Beach, Bakers Creek and <strong>Mackay</strong>,where <strong>the</strong> prevail<strong>in</strong>g south-easterly w<strong>in</strong>ds would blow dust far<strong>the</strong>r and over more residential areas(Fig. 5).The percentages <strong>of</strong> coal dust fall<strong>in</strong>g on residential areas ranged from 1-30 per cent. Values less thanone per cent were considered to be zero per cent and not counted. Given that coal exports couldfirst double to 170Mtpa and <strong>the</strong>n quadruple <strong>in</strong> 20 years to 340Mtpa it is reasonable to expect that<strong>the</strong>se percentages <strong>of</strong> <strong>PM10</strong> coal dust particulates would <strong>in</strong>crease significantly. This is because coalrail l<strong>in</strong>es will <strong>in</strong>crease to eight, and much more coal would be unloaded and placed on conveyor beltsfor transport to <strong>the</strong> coal shipp<strong>in</strong>g. Coal dust would also be lost dur<strong>in</strong>g load<strong>in</strong>g <strong>the</strong> coal ships. The coalstock piles at Dudgeon Po<strong>in</strong>t will be up to 20 m high as <strong>the</strong>y will sit on a 5m base above storm surgelevels. Their additional height means <strong>the</strong>y will lose more coal dust than lower stock piles elsewhere<strong>in</strong> Hay Po<strong>in</strong>t port lands.Fig. 4 Location <strong>of</strong> On-Site and Surround<strong>in</strong>g Residential <strong>Dust</strong> Deposition Monitored Sites at Hay Po<strong>in</strong>t.<strong>Mackay</strong> Conservation Group. <strong>Dust</strong> <strong>Up</strong> Report.
