2. Environmental Projects/ActivitiesManagement Area Project Status
Reporting EPL 11745 Annual Return •Completed and submitted
Air Quality Pollution Reduction Programs
Real-Time Dust Management
•PRP U3 Handling overburden in adverse weather conditions – weather station alarming and response protocol is now being implemented.•Several alarms received from the Real-time dust unit (TEOM) in November resulting from local bushfires and hazy conditions in the valley. No operations and wind direction not consistent with contribution from the mine. Alarms also received on 9-Jan from power outage.
Flora 2014 Noxious Weed Program •Completed
Fauna 2014 Wild Dog Control Program Completed. Program will reassessed in 2015.
Noise • Quarterly Noise Assessment• Mobile Plant Assessment• Real-Time Noise
•Continuous improvement Projects
•November assessment completed.•Scheduled for March 2015.• System operational for period 8pm to 8am. Noise profiles continue to be monitored and generally indicate no exceedence of the performance criteria due to mining/CHPP activities. •Several alarms were received during the quarter and investigation generally found contributions from birds & insects, traffic and freight trains. Occasionally dull noise from the plant was audible.•During December the RTN unit had been giving intermittent unusual high readings over extended time periods. Novecom performed attended monitoring and found inconsistency in the readings. The unit was replaced on 9-Jan-15 to undergo repairs. •No changes during the last quarter.

Management Area Project Status
Rehabilitation • BRN Pit
•Roseville West Pit
•Shaping and topsoiling of waste dump completed.•Rehabilitation works of approx. 40 ha of BRN waste dump completed including new areas and existing rehab requiring maintenance.•Rehabilitation of BRN go-line area.•Improvement works on existing Roseville rehab.
Lighting •CHPP Lighting •The continual improvement of the control of lighting, to enable us to easily turn off lights when not required.
Bushfire Management •Bushfire Management • RFS visited site with Alan Andrews to discuss a bushfire reduction burning plan. Due to RFS resources and weather condition during previous quarter back-burning was not possible. RFS have proposed a plan the next 2-3 years management.

Coal: Black sharp angled grains with glossy conchoidal fractures or dull with cellular features.
Dirt/Minerals: Subhedral to euhedral crystalline grains including fine sand, clay and other fine mineral particulates.
Insects: Whole insects such as spiders, ants, moths or outer parts of insects including wings, legs and exoskeletons.
Vegetation: Plant debris and algae including trichomes, decomposed organic matter and charred particulates showing characteristic cellular plant structures.
Contamination: Gelatinous material such as bird droppings

• All sites generally well below NEPM 24hr average level.
• Spike in October is due to fires to the west and south of the mine site. Not considered a breach of
licence criteria as the Development consents exclude extraordinary events such as bushfires.

Air Quality – TEOM (Real Time) Monitoring

• Several alarms received from the Real-time dust unit (TEOM) in November resulting from local bushfires and
hazy conditions in the valley, particularly 1-5 November 2015. No operations and wind direction not consistent
with contribution from the mine.
• Zero/negative values are due to moisture vapour/dew drying on filter creating small negative mass readings.
