5.0 Depositional Dust Sampling
Fifteen depositional dust gauges were collected for the reporting period. Sampling
and analysis is conducted in accordance with AS 3580.10.1 – 1991 – Determination
of particulates – Deposited matter – Gravimetric method. All gauges were
analysed for insoluble solids (IS) and ash residue (AS). Field observations include
water quantity and quality, and any visible contaminants in the sample.
Insoluble solid results are reported on the annual average of 4g/m2/month of all
uncontaminated results which are not located on Wambo Coal owned land. No
depositional dust gauge locations were outside the prescribed criteria level for the
reporting period.
March results are presented in Table 3 and Figure 2 below.

All units sampled Total Suspended Particulates (TSP) over a 24-hour period on a six
day cycle, in accordance with AS 2724.3 – 1984 – Determination of total
suspended particulates (TSP) – High volume sampler gravimetric method.
Reported yearly means for locations are within the reporting criteria of 90g/m3.

7.0 Blast Events
Four monitoring sites measure ground vibration and air blast overpressure for blasts
conducted at Wambo. Six blasts were conducted during the reporting period.
Monitoring at all four sites is conducted under the blast monitoring requirements set
out in the Wambo EPA licence (EPL 529) and DA 305-7-2003. The blasting criteria
are summarised in Table 5 below.

8.0 Noise Monitoring
8.1. Attended Monitoring
Attended noise monitoring is undertaken on a monthly basis and can be found on the
Peabody Wambo website at www.peabodyenergy.com/content/404/Australia-Mining-
New/New-South-Wales/Wambo-Mine.
8.2. Real Time Monitoring
Real time noise monitoring results are reported in a quarterly format and can be found
on the Peabody Wambo website at www.peabodyenergy.com/content/404/Australia-
Mining-New/New-South-Wales/Wambo-Mine.
9.0 Real-Time Air Quality Monitoring
Four real time Tapered Element Oscillating Microbalance (TEOM) units were in
operation during the reporting period. The sites are located at Coralie (PM01), the
Caban residence (PM02), Thelander residence (PM03) and the Muller residence
(PM04). These units measure particulate matter less than 10 microns in diameter
(PM10) on a continuous basis and provide a 24 hour average result. These units
operated and sampled in accordance with AS 3580.9.8 - 2002, Method for Sampling
and Analysis of Ambient Air - Determination of Suspended Particulate Matter -
PM10 Continuous Direct Mass Method using a Tapered Element Oscillating
Microbalance Analyser.
March results are presented in Table 7 and Figure 4 below.
All PM10 sites were within the yearly and 24hr average criteria average criteria limits of
30ug/m3 and 50ug/m3 respectively.
