The location of these monitors can be found in Appendix A – HVO Monitoring Locations Plan. 2.1 Depositional Dust Monitoring 2.1.1 Depositional Dust Results Results of Depositional Dust Monitoring (EPA Monitoring Point 1, Condition M2.2) are shown in Table 1. The outcomes of annual average compliance assessment will be reported in the Annual Review. The last sample date for Depositional Dust was 21 May 2015; the data was obtained on 12 June 2015.

The location of these monitors can be found in Appendix A – Hunter Valley Operations Monitoring Locations. The last date sampled was the 30 May 2015; the data was obtained on 16 June 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).
