Management Area Project Status Air Quality

Pollution Reduction Programs
Real-Time Dust Management
PRP U2 Haul road wheel generated dust monitoring – Three

rounds of monitoring completed with control efficiencies of 92%, 92% and 93%. Final report to demonstrate 80% control efficiency to be sent to EPA in August 14.

PRP U3 Handling overburden in adverse weather conditions –

Performance indicators for adverse weather conditions have been developed and weather station alarming established. Following an alarm being received an investigation would be undertaken to determine the need for any management measures.

No verified alarms have been received.

Flora

2014 Noxious Weed Program
Commenced April – focusing on Giant Parramatta Grass &

Blackberry Fauna

2014 Wild Dog Control Program
Commenced April 2014 (trapping)
Scheduled to be repeated later in 2014

Management Area Project Status Noise

CAT D10 dozer to 110dB
New conveyors to be consistent with current low

noise technology

Duralie train unloading facility
Rail loop acoustic barriers
Low noise idlers on CV18 and CV17
Enclosure on coal loader
Real-Time Noise
Complete
Ongoing
Alsynite replaced with standard sheeting (complete).
Complete August 2013.
Noise assessment conducted with reductions of 9-16 dB

recorded.

Complete; 6dB gain achieved per conveyor
Completed February 2014.
System operational. No alarms received in last quarter.

Real-time noise monitoring profiles continue to be monitored and indicate no exceedence of the performance criteria due to mining operations. Lighting

Lighting optimisation (reductions)
Implementation of change to prevent daytime use of

exterior CHPP lighting.

Further optimisation work planned for night-time
perations
Stockpile lighting now controllable, lights turned off during

the day Rehabilitation

Roseville West Pit
BRN Pit
Old Main Pit
5 Ha cover crop of millet established, planting of additional

pasture grasses completed

Planting of 13 Ha of native plant species completed
Reshaping of southern edge of main pit in progress,

planting of cover crop upon completion of shaping – May.

Air Quality – Petrographic Analysis

16 Samples are examined under a stereo-microscope (50x) to determine the nature

f the dust deposits.

The relative amount of dust deposits on the filter paper is described as: Trace

traces only on filter paper

Light

thin cover over most of the filter paper

Moderate

thin cover over filter paper

Heavy

thicker cover over filter paper

The dust is grouped into:

coal
inorganic (clays, etc.)
insect and plant remains

The proportions are described as: Major - >30% Minor - 5% - 30% Trace - <5% Slight trace- <1% Note: Estimated percentages are considered as: 5% +/- 2% 10% +/- 5% 30% to 80% +/- 10% 90% +/- 5% 95% +/- 2%
