SURFACE WATER QUALITY
The following parameters pH, Total Suspended Solids (TSS mg/L), Electrical Conductivity (EC µs/cm) and Oil and
Grease (mg/L) are monitored at Licenced Discharge Point LDP001 and LDP002 daily during discharge in accordance
with the requirements of Environmental Protection Licence 365.
Table 2 and 3 show a summary of these results, whilst Figures 1 to 3 are graphical representations. Additional
pollutants are required to be monitored monthly during discharge; these results can be found in Table 4.

WATER VOLUME
Water volume discharged off site is measured through licence discharge points (LDPs). Environmental Protection
Licence 365 limits the maximum volume of water to be discharged at LDP001 to 5000 Kilolitres per day (note:
condition L3.2 of EPL365 permits the volume limit to be exceeded if a rainfall event greater than 10 mm occurred in
the prior 24 hours).
A summary of daily total water volume discharged is provided below.

Depositional dust monitoring data indicates that dust deposition results for October 2017 range from 0.2 g/m2/mth to
2.9 g/m2/mth. The rolling annual average for each of the dust gauges in October 2017 is shown in Table 7 and Figure
9. All rolling annual averages are below the 4 g/m2/month limit criteria.

The objective of installing and commissioning a Tapered Element Oscillating Microbalance (TEOM) Air Quality
Monitoring Station (AQMS) at the Cooranbong Services Site in June 2013 was to monitor continuous particulate
matter at EPL 365 Point 6 for the following parameters associated with the mining activities in accordance with
Condition M2.2 Air Monitoring Requirements of the Environment Protection Licence (EPL) Number 365:
Total suspended particulates (TSP) and
Particulate matter with an aerodynamic diameter less than 10 microns (PM10) concentration.
The 24-hr average PM10 concentrations were in compliance with the OEH and NEPM 24-hr criterion of 50 µg/m3
during the October 2017 monitoring period. The maximum recording for the monitoring period was 27.03µg/m3
which occurred on 10 October 2017. The rolling annual average PM10 concentration was in compliance with the
OEH and NEPM annual criterion of 30µg/m3. The rolling annual average recording is 16.2µg/m3.
The average TSP concentration was in compliance with the NSW Approved Methods annual average criterion of
90µg/m3 during the October 2017 monitoring period. The maximum recording was 31.78µg/m3 which occurred
on 25 October 2017. The rolling annual average TSP concentration was in compliance with the OEH and NEPM
annual criterion of 90µg/m3. The rolling annual average recording was 17.1µg/m3.
