2. SURFACE WATER QUALITY
Myuna Colliery has two Licenced Discharge Points (LDP) for water. The following parameters;
pH, Total Suspended Solids (TSS mg/L) and Oil and Grease (mg/L) are monitored at Licenced
Discharge Point LDP00A and LDP00B daily during discharge in accordance with the
requirements of Environmental Protection Licence (EPL) 366.
Table 3 shows a summary of the monitoring results which have concentration limits specified in
the EPL, while figures 1 to 3 are a graphical representation. There were no discharges from LDP
A during the report period.

3. WATER VOLUME
Water volume discharged off site is measured through licence discharge point B (LDP B).
EPL366 set a limit on the maximum volume of water to be discharged per day through LDP B.
The daily volume limit for LDP B is 13000 kL.
A summary of total water volume discharged is provided below.

DG – Dust Gauge
A graphical representation of depositional dust monitoring data is shown in Figure 5
Figure 5 Monthly Dust Deposition Gauge Results
Depositional dust monitoring data indicates that dust deposition results for November range
from 0.7 g/m2/month to 5.3 g/m2/month. The Dust Deposition Gauge DG3 from 19 Oct -20
Nov 2015 was heavily contaminated with material not associated with deposited dust. The
visual analysis from the field staff indicated that the sample was primarily composed of bird
droppings and insects – this was confirmed by comments from Steel River, the NATA
10
accredited laboratory who analysed the sample, who found bird droppings, insects and plant
material as the principle components.
As such, there is no way or approved method of separating the actual deposited dust from
the contamination and the result for this month is not representative of true dust deposition
at the site and should not be used in annual averaging.
The Myuna Colliery Project Approval 10_0080 contains criteria for a maximum total
deposited dust annual average of 4 g/m2/month. The rolling annual averages for each of the
dust gauges in November 2015 are shown in table 6 and Figure 6 below. All rolling annual
averages are below the 4 g/m2/month criteria. The anomalous result from DG 3 is not
included in the annual average data.
EPL 366 does not contain a limit condition for depositional dust.

4.2 High Volume Air Sampling (HVAS)
The Myuna Colliery Project Approval 10_0080 contains a criteria for PM10 (particulate matter
less than 10 micrometres) and TSP (Total Suspended Particulates). There were no exceedances
of the Project Approval limits. EPL366 does not contain limit conditions for PM 10 and TSP.
A summary of monitoring results for October 2015 is provided in Tables 7 & 8, figures 7 & 8
below.

5. QUARTERLY MANGANESE MONITORING
In accordance with Special Condition 9, E1 Additional Monitoring of EPL366, Myuna Colliery
undertakes a quarterly manganese monitoring program in Wangi Bay. The locations of this
monitoring can be found in Plan MY10950 attached.
The quarterly monitoring was undertaken on the 4th September 2015. The results are
provided in table 9 and figure 9 below.

6. QUARTERLY NOISE MONITORING
Attended noise monitoring is undertaken quarterly in accordance with the Myuna Colliery
Project Approval. Noise monitoring is consistent with the OEH Industrial Noise Policy and
Australian Standard AS 1055 Acoustics, Description and Management of Environmental
Noise. The third quarter noise monitoring was conducted 1st – 2nd September 2015.
The third quarter monitoring is summarised below.

Attended noise compliance monitoring at designated noise sensitive receivers has taken place in
accordance with the requirements of Myuna Colliery EPL (EPL 366, latest revision dated 13 May
2015) and the Myuna Colliery Noise Management Plan (dated July 2012).
Colliery noise was inaudible at all locations during the day. The Colliery was audible at three
locations during the evening and at one location during the night-time. LAeq levels were largely
controlled by extraneous noise sources such as passing traffic, whereas LA90 levels were
controlled by traffic on nearby roads or Colliery operations during the evening and night. Colliery
operations were subjectively observed to contribute little to the measured LAeq noise levels
during any period of the day. Definitive compliance with EPL noise limits was, however, difficult
to determine through direct measurement due to the influence of extraneous noise events.
