METROPOLITAN COAL PROJECT INDEPENDENT ENVIRONMENTAL AUDIT
4.2.4 Particulate Matter
A high volume air sampler (HVAS) located at 12 Robertson Street, Helensburgh measures 24 hour
average PM 10 concentrations proximal to the mine.
PM 10 monitoring recorded results indicated that the annual average particulate matter concentration in
2010 was 17.7 µg/m 3 and in 2011 was 11.8 µg/m 3 , both less than the EPL and Project Approval
criterion of 30 µg/m 3 . The data set does indicate a small number of exceedances above 30µg/m 3 that
occurred in January and March 2010 and one exceedence on 9 March 2011.
The highest 24-hour average PM 10 concentration during 2010-2011 was 71.9μg/m 3 , recorded on 10
March 2011 (above the PM 10 24-hour impact assessment criteria of 50μg/m 3 ). It is considered that this
elevated recording was associated with prescribed burning being conducted in the Helensburgh area
between 4 and 9 March 2011 (same dates as affected the PM 10 results).
4.2.5 Real-Time Monitoring System
Metropolitan Coal established a Tapered Element Oscillating Microbalance (TEOM) real-time air
quality monitoring system and meteorological station at 12 Robertson Street Helensburgh during
2010. The TEOM results indicated full compliance with the annual and daily limits set by the Project
Approval.
4.2.6 Complaints
Two dust related complaints were received in 2010 and one complaint in 2011. Dust complaints
received during 2010 and 2011 have been less than the historical average of the previous six years.
Conclusion:
Dust management at the Metropolitan Colliery surface facilities areas is managed in a satisfactory
manner with monitoring results demonstrating compliance with the EPL and Project Approval criteria.
4.3 Biodiversity 1
[Project Approval Schedule condition 4(c) and 6(f); and Schedule 7 condition 2]
4.3.1 Biodiversity Management Plan
[Project Approval Schedule 3 condition 4(c) and 6(f)]
The Biodiversity Management Plan was prepared to satisfy the requirements of Project Approval
Schedule 3 condition 4(c) and 6(f) and Schedule 7 condition 2 for Long-walls 20-22 was submitted to
the DoP for approval on 14 May 2010.
The Biodiversity Management Plan provides a comprehensive review of the performance of the
project in relation to the implemented monitoring program and management protocols for terrestrial
ecological values associated with the approved project.
The Biodiversity Management Plan addresses the requirements outlined in Project Approval Schedule
7 condition 2 and adequately addresses each component:
