4.2.3 Dust Monitoring Results
Dust monitoring results have demonstrated compliance with Project Approval Schedule 4 conditions
11 and 12 during 2010 and 2011. There were only three (3) occasions in 2010-2011 when dust
deposition results exceeded the Project Approval maximum total deposited dust level criteria of
4g/m2/month:
Two readings above the Project Approval criteria occurred at the EPA licenced dust gauge at the
Mine Entrance (DG3 - EPA ID 3) in August 2010 and January 2011, and one exceedence at
additional gauge DG7 at 32 Old Station Road occurred in August 2010:
Mine Entrance dust gauge (DG3) recorded 5.0 g/m 2 /month - DG3 is located on land owned by
the Metropolitan Colliery near the main entrance, which is more likely to be exposed to dust
from the movement of vehicles in and out of the mine site. (It is also noted that DG3 is not
representative of a sensitive receptor).
32 Old Station Road (DG7) recorded 6.0 g/m 2 /month in August 2010- there is no immediate
mining source located in close proximity to DG7 that would result in this level of dust. It was
considered most likely that DG7 was exposed to a localised source of dust that resulted in the
measurement of 6.0 g/m 2 /month. The increased deposition value could have been caused by
Council construction activities proximal to the dust gauge during August.
All other gauges exhibited dust deposition levels below 4.0 g/m 2 /month during 2010 and 2011.
