- Quarterly Environmental Monitoring Report - October to December 2023 Andrew Raal went through the Report with the following comments:
- Air Quality - Smoke and Dust from the Pilliga Bushfire caused slight elevation for a few days. This was reported and accepted by the Department of Planning, Housing and Infrastructure (DPHI) as being due to an extraordinary event and not mine related.
- Werris Creek Mine deposited dust - "Cintra" averaged "4" which is within the 12-month average.
4.0 Blasting - Total of fifteen blasts - all within required levels.
5.1.1 Monitoring Data Results - 2023 Monitoring will be in the Annual Report - this will be published on the Whitehaven Coal web page.
- General Business
- Closure of Mine extended to April 2024 with completion by 30 June 2024.

1.0 METEOROLOGY
1.1 WEATHER STATION
Werris Creek Coal (WCC) collects meteorological data from the onsite weather station located on the top level of the overburden emplacement. The following table summarises rainfall data for the last three months. The monthly rainfall during the reporting period was below the historical average for October 2023 but above November-December 2023. Directional wind data, presented in the wind-rose figures below, indicate the prevailing wind direction during the reporting period was predominantly from the south during October-November 2023 and from the north in December 2023.

- AIR QUALITY
- HVAS (PM10) and TEOM (PM10 & PM2.5)
WCC operates five High Volume Air Samplers (HVAS), four sites measuring particulate matter less than 10 microns (PM10) and one site measuring total suspended particulate (TSP) matter. HVAS sampling is scheduled every 6 days for a 24-hour run period in accordance with Environment Protection Authority (EPA) guidelines. Results are reported in micro grams per cubic metre (µg/m3) of air sampled. In addition, WCC operates a Tapered Element Oscillating Microbalance (TEOM) monitor in Werris Creek measuring real time PM10 and PM2.5 (particulate matter less than 2.5 microns) dust levels. Dust monitoring locations are identified in Figure 1.

2.1.2 Discussion - Compliance / Non-Compliance
All TSP, PM10 and PM2.5 dust results were within criteria during the period except for an elevated PM10 24hr average result of 52.7 ug/m3 that occurred on 9 December 2023 which was due to bush fires in the area. Incident was reported to the DPHI (Department of Planning, Housing and Infrastructure) and was accepted as an extraordinary event. Elevated PM10 results were also recorded for the 19/12/2023 HVAS run for sites HVP20 Tonsley Park and HVP98 Glenara result of Pilliga bushfire events. The exceedances were reported to the DPHI and accepted as extraordinary events.
2.2 WERRIS CREEK MINE DEPOSITED DUST
Deposited dust monitoring measures particulate matter greater than 30 microns in size that readily settles out of the air related to visual impact. Dust deposition is monitored at 18 locations around WCC. Sampling is scheduled monthly in accordance with EPA guidelines and results are reported as grams per square metre per month (g/m2.month). Dust monitoring locations are identified in Figure 1.

3.1.2 Discussion - Compliance / Non-Compliance
Noise from Werris Creek Coal Mine was inaudible at a high percentage of the monitoring sites during the quarter. Throughout the period, Werris Creek Coal Mine adjusted mining operations and shut down equipment at various times to reduce noise generation potential in response to noise levels measured at the real time noise monitors.
3.2 Noise complaints
There was one noise complaint recorded during the period.
4.0 BLASTING
During the reporting period there was a total of 5 blasts fired by WCC with monitoring of each blast undertaken at "Glenara", "Kyooma", "Werris Creek South" and "Werris Creek Mid". Compliance limits for blasting overpressure is 115dBL (and up to 120dBL for only 5% of blasts) and vibration is 5mm/s (and up to 10mm/s for only 5% of blasts). Blast monitoring locations are identified in Figure 3.

4.1.2 Discussion - Compliance / Non-Compliance
All blasts over the period complied with maximum licence limits (120dB(L) and 10mm/s) as well as the 95th percentile limits (115dB(L) and 5mm/s).
4.2 BLAST COMPLAINTS
There were no blast complaints during the reporting period regarding vibration.
5.0 WATER
The groundwater monitoring program monitors groundwater levels bi-monthly and groundwater quality six monthly. Surface water monitoring is undertaken quarterly.
5.1 GROUND WATER
Groundwater monitoring is undertaken to identify if there are any impacts on groundwater quality and water levels as a result of the mining operations. WCC monitors approximately 38 groundwater wells/bores and piezometers in the key aquifers surrounding WCC including Werrie Basalt (next to WCC and further afield) and Quipolly Creek Alluvium. Groundwater level surveys were completed between 27-29 November 2023. Groundwater monitoring locations are identified in Figure 4.
