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 1 – 9 in accordance with the requirements of Environmental
Protection Licence 443.
There were no discharges from Awaba Colliery Licenced Discharge Points during the monitoring period.
WATER VOLUME
Water volume discharged off site is measured through licence discharge points (LDPs). Environment Protection
Licences (EPLs) set limits on the maximum volume of water to be discharged for a given period.
The volume limits for EPL443 Licenced Discharge Points are listed in table 2

* Results removed due to contamination of the sample. Specific information can be found below.
The following high readings were removed from the tables and graphs due to contamination of the results. The
following provides further information:
July – DG3 recorded a reading of 13.1 g/m2/month. A breakdown of the material shows 50% of the result
was a combination of Vegetation Matter and Polysaccharide slime.
September – DG3 recorded a reading of 7.8 g/m2/month. 50% of the dust was a combination of Vegetation
Matter and Polysaccharide slime.
February – DG3 recorded a reading of 4.4 g/m2/month. 60% of the dust was a combination of Vegetation
Matter and Polysaccharide slime.
June – DG3 recorded a reading of 11.8 g/m2/month. 60% of the dust was a combination of Vegetation Matter
and Polysaccharide slime.
A graphical representation of depositional dust monitoring data is shown in Figure 1.

Figure 1. Monthly Dust Deposition Gauge Results
Depositional dust monitoring data indicates that dust deposition results for June range from 0.1 g/m2/month to 11.8
g/m2/month.
Awaba Colliery development consent contains the following limit criteria for dust;
Annual average maximum total deposited dust level of 4 g/m2/month.
Maximum increase in Annual Average deposited dust level, 2 g/m2/month.
The rolling annual average for each of the dust gauges in June 2015 are shown in Table 4 and Figure 2 below.

NOISE MONITORING
Attended noise monitoring is undertaken quarterly in accordance with the Awaba Colliery Project Approval. A noise
monitoring survey was conducted between the 9th & 11th of June 2015 at two monitoring locations (Noise Sensitive
Receivers) surrounding the Awaba Colliery operations.
The results of the environmental noise compliance assessment conducted between the 9th & 11th of June 2015
indicated noise levels generated by the Awaba Colliery were compliant with the applicable noise criteria at all rural /
residential monitoring locations during day, evening and night periods.
The next round of noise monitoring is planned to be undertaken in August 2015.
COMPLAINTS
There were no community complaints during the month regarding Awaba Colliery.
