1 INTRODUCTION
Moolarben Coal Operations Pty Ltd (MCO) operates the Moolarben Coal Mine located at 4250 Ulan Road, Ulan,
NSW which is approximately 40km north-east of Mudgee, within the Western Coal Field. It is located east of the
Ulan Coal Mine and west of the Wilpinjong Coal Mine.
The purpose of this report is to provide a monthly update of monitoring data in accordance with the requirements
of Environmental Protection Licence (EPL) 12932, section 66(6) of the POEO Act and the MCO Project Approvals
05_0117 and 08_0135.
To view MCO EPL 12932 in full please refer to the link below.
http://www.environment.nsw.gov.au
On 26 May 2016 EPL 12932 Variation was approved. The variation replaces all previous versions of the licence.
2 MONITORING REQUIREMENTS
The Moolarben Environment Protection Licence (EPL) 12932 specifically requires the monitoring of:
Eight dust gauge sites (dust deposition monitoring);
Three Tapered Element Oscillating Microbalance (TEOM) PM10 sites;
One PM10 High Volume Air Sampler (HVAS);
Three water discharge points;
Two surface water quality sites;
Four effluent discharge sites;
Blast monitoring;
Noise monitoring; and
Meteorological monitoring.
Monitoring of sites not required by the EPL are carried out in accordance with MCO Environmental Monitoring
Program (EMP) and Project Approval 05_0117 and 08_0135.
The MCO EPL12932 Environmental Monitoring Network is shown on Figure 1.

3 DUST DEPOSITIONAL GAUGES
During December 2016 samples from eleven dust gauges were collected and analysed by a NATA accredited
laboratory (Table 1). As at 31 December 2016 no depositional dust gauges had recorded an exceedance of the
12-month rolling average criteria of 4 g/m2/month (Figure 2).
Table 1: Dust Deposition Results – December 2016
Note: Contaminated results are not included in the 12 month rolling average
Monthly results above 4g/m2/month are not classed as an exceedance of criteria as the criteria is an annual average of 4g/m2/month

4 REAL TIME PM10 MONITORING
Continuous particulate matter less than 10μm (PM10) monitoring was conducted by four tapered element
oscillating microbalance (TEOM) units at Moolarben during December 2016.
The EPA identification numbers 15, 17 and 27 refer to the TEOMs installed on Ulan-Wollar Road (TEOM06), Ulan
Public School (TEOM 1) and Southern Ridge Road (TEOM 5) respectively. In addition, a fourth unit is located on Ulan
Road (TEOM 4) with data used for management purposes only.
No results were above the daily or annual limit (Table 2). Real time PM10 results for December 2016 are illustrated
in Figure 3.

5 HIGH VOLUME AIR SAMPLER (HVAS) PM10 MONITORING
Moolarben Coal monitors PM10 with two high volume air sampler (HVAS) units located on John Street in Ulan
Village and on Ridge Road. The Ridge Road HVAS is not required by the EPL. Samples were taken every six days with
a 100% data capture rate for the period. The annual rolling average and PM10 results for December 2016 are
presented graphically in Figure 4.

8 NOISE
In accordance with the MCO Noise Management Plan attended noise compliance monitoring is undertaken
monthly by a suitably qualified and experienced person. Monthly monitoring was conducted in December 2016
with results obtained on 17 January 2017. All monitoring measurements were undertaken during night time, except
for monitoring site NA1 (Ulan School) which was monitored during the day.
A brief description of the measurements at all sites are shown below and full attended noise monitoring results for
December 2016 are shown in Table 7.
NA1, Ulan School
During the day measurement on 14 December 2016, MCO was inaudible. Birds generated the measured LA1, LA10 and LAeq. Breeze in foliage generated the measured LA90. Road traffic noise, aircraft, insects and noise from a nearby school were also noted. The wind speed during this measurement was 3.5 m/s with a stability class of A. NA6, Lower Ridge Road
During the night measurement on 13 December 2016, MCO was inaudible. Dogs were primarily responsible for generating the measured LA1 and contributed to the measured LA10 and LAeq. Insects and frogs were primarily responsible for the measured LA10 and LAeq and generated the measured LA90. Birds, livestock and road traffic noise were also noted. The wind speed during this measurement was 1.1 m/s with a stability class of D. NA12, Winchester Crescent
During the night measurement on 13 December 2016, MCO was inaudible. Frogs and insects were primarily responsible for measured levels. Road traffic noise, aircraft, birds, dogs, livestock and owls were also noted. The wind speed during this measurement was 0.9 m/s with a stability class of D.

9 BLASTING
Blast monitoring is required by EPL 12932 at Ulan School (BM1). Monitoring is also undertaken at Ridge Road
(BM5). A total of eight blasts were conducted during December 2016. The blast results are shown in Table 8.

10 METEOROLOGY
Weather data is measured continuously at the Ulan Road Weather Station (Weather Station 3). Temperature (2m)
and rainfall data are presented below. In addition to these parameters the weather station also measures wind,
temperature (10m), solar radiation, humidity, atmospheric pressure, and sigma theta. All data was captured during
December 2016.
