AIR QUALITY
To monitor regional air quality, HVO operates and maintains a network of nine depositional dust gauges and four Total Suspended Particulate (TSP) High Volume Air Samplers
(HVAS) on private land surrounding the mining operations. The location of these monitors can be found in Appendix A – HVO Monitoring Locations Plan.
2.1

SURFACE WATER
3.1
Mine Water Discharge Monitoring
HVO participates in the Hunter River Salinity Trading Scheme (HRSTS), and maintains six monitoring locations associated with this scheme (EPA Monitoring Points 3, 4, 5, 6, 7
and 8, Condition M2.3) as follows:

EPA Identification Number 3 – Discharge Pipe from Dam 11N

EPA Identification Number 4 – Discharge end of outlet pipe on Parnell’s Dam

EPA Identification Number 5 – At the discharge end of the alluvial lands discharge pipeline

EPA Identification Number 6 – In Farrell’s Creek within 100m, and upstream of the confluence of flow from POINT 3

EPA Identification Number 7 – In Farrell’s Creek within 100m, and downstream of the confluence of flow from POINT 3
4

EPA Identification Number 8 – Outlet of discharge pipe from Lake James storage dam
The location of these sampling points can be viewed in Appendix A: HVO Monitoring Location Plan
During the reporting period no mine water was discharged under the HRSTS.

BLAST MONITORING
4.1
Blast Monitoring
In accordance with the requirements of Condition M8.1, Hunter Valley Operations maintains a network of blast monitors to measure airblast overpressure and ground vibration for
all blasts carried out at HVO. The location of these monitors can be found in Appendix A –Blast Monitoring Location Plan. The last date sampled was the 31 March 2015; the data
was obtained on 8 April 2015.
During the reporting period no blasts exceeded the 115dB(L) threshold for airblast overpressure or the 5mm/s threshold for ground vibration.
Blast monitoring results are detailed in Tables 3 (Airblast Overpressure) and Table 4 (Ground Vibration).
