Strong winds prompt a number of PM10 level exceedances in the Upper Hunter


Strong winds across the Hunter have prompted a number of PM10 level exceedances in the Upper Hunter. 

The Department of Planning Industry and Environment has told Radio Hunter Valley the deep cold front combined with the drought conditionshas raised large amounts of dust between Dubbo and Armidale, with that dust landing in the Hunter region between 2 and 4pm yesterday afternoon. 

That prompted exceedances in Muswellbrook and Aberdeen yesterday afternoon and today at Muswellbrook, Mason Dieu, Camberwell, Singleton, Singleton South, Jerrys Plains, Warkworth and the Lower Hunter.

The Department also added:

"Increased PM10 levels associated with these high winds continued overnight, leading to additional exceedances further south in Singleton and Mount Thorley,"

"Strong winds are likely to continue today and tomorrow, with high PM10 in the Upper and Lower Hunter expected as a result of these conditions."

The wind whipped up at the Mount Arthur Coal mine at around 2pm yesterday. 

A spokesperson has said that operations were stopped intermittently in a bid to minimise the dust at the site. 

At other mines in the area, MACH Energy's Mount Pleasant mine restricted their operations until 3:41pm yesterday and after that ceased all dust generating activites.

A spokesperson added that "during the shutdown we had six water carts in operation".

"Operations were ceased this morning, Friday 9th August and only water carts are operating."
