1 Boral Maldon Cement Works POELA Act 2011 Monitoring Data Boral Cement Maldon, NSW Environmental Protection Licence No. 212 Explanation of units of measure: mg/m 3 = milligrams per cubic metre g/m2/month = grams per square metre per month μg/m 3 = micrograms per cubic metre mg/l = milligrams per litre NTU = Nephelometric Turbidity Unit Record updated on: 21 November 2017 Maldon Cement Plant s webpage became live in July The monitoring data has been uploaded to the internet for public use first time in July 2014 (including historical data back to April 2012) and are updated monthly. This report relates to calendar year Ambient air/dust monitoring 2.1 Dust Deposition Gauges The measurement is expressed as Total Insoluble Matter (g/m 2. month) (grams/square metre/month). This test measures the levels of the coarse dust (generated mostly from unsealed roads, raw material handling, open stockpiles, etc.). It is a measure of dust nuisance (dust on cars, washings, window panes) in the immediate vicinity of the source, as the heavy dust settles quickly and doesn t travel far. It is not an indication of potential health problems as it doesn t penetrate into the respiratory system due to a large size of dust particles. Licence limit: Not specified. The NSW State guideline of 4 g/m 2 /month (gram/square metre/month) (presented as 12- month rolling average) was adopted.

4 Berrima Colliery in Medway POELA Act 2011 Monitoring Data Berrima Colliery, Medway, NSW Environmental Protection Licence Number 608, held by Boral Limited Explanation of units of measure: mg/m 3 = milligrams per cubic metre g/m 2 /month = grams per square metre per month μg/m 3 = micrograms per cubic metre mg/l = milligrams per litre ML/d = megalitres per day Record updated on: 13 November Water monitoring Berrima Colliery has two licensed discharge points and four ambient background monitoring points: Discharge Points: Mine Adit - Naturally occurring groundwater is captured in the underground workings and is discharged into the Wingecarribee River. The monitoring point is referred to as the V Notch Weir Point 4). Pit Top Dam Referred to as the Chitter Dam, this dam collects water runoff from the surface facilities area. This dam did not discharge during the reporting period. Ambient background monitoring points: Wingecarribee River upstream of the mine adit discharge at Old Hume Highway Crossing at Berrima Point 9). Wingecarribee River upstream of the mine adit discharge at Macarthur s Crossing Point 10). Wingecarribee River downstream of the mine adit discharge at Biloela Camp Site Point 11). Wingecarribee River downstream of mine adit discharge at Black Bob s confluence Point 12). Ambient monitoring points provide background data for reference purposes and were added to the licence on 23 December 2013 along with additional monitoring parameters for the discharge points. The licence was amended on 9 th October The changes relate to a reduction in frequency of monitoring to two-monthly for the licensed discharge points and the ambient background monitoring locations Page 1

17 3. Ambient Air/Dust Monitoring Berrima Colliery has 4 dust monitoring locations as described below: Mine Office Dust Deposition (Gauge 1) Medway Village Dust Deposition (Gauge 2) Loch Catherine Coal Stockpile Dust Deposition (Gauge 3) Mine Entry Road PM10 Atmospheric Dust (Gauge 4) 3.1 Dust Deposition Gauges: Total Insoluble Matter (grams per square metre per month) Gauges 1 to 3 are dust deposition gauges which measure the levels of coarse dust. It is a measure of dust nuisance rather than an indication of potential health problems as this dust fraction does not penetrate into the respiratory system. Licence limit: Not specified Adopted limits: For dust deposition, the NSW State guideline of 4 g/m 2 /month (presented as a 12-month rolling average) has been adopted. Table 5 Dust Deposition Data Dust Deposition Gauges (g/m 2 /month as 12-month rolling average) Site 1 Office Site 2 Medway Village Site 3 Loch Catherine December /01/17 6/02/17 January /02/17 6/02/17 February /03/17 8/03/17 March /03/17 4/04/17 April /05/17 5/05/17 May /06/17 5/06/17 June /07/17 4/07/17 July /08/17 8/08/ Page 14

19 3.2 Atmospheric Dust Sampling Berrima Colliery is required to measure the very small fraction of total suspended particulate matter, namely the 10 micron fraction (PM10). This test measures the levels of the very fine dust suspended in the air which is a measure of potential health effects (irritation of the respiratory tract) as the small particles can penetrate into the airways and the lungs. Fine dust can persist in the atmosphere for days or even months before it settles and can travel some distance. Gauge 4 is located near the mine entrance which is midway between the mine facilities and the village of Medway. Licence limit: Not specified Adopted limits: the National Environment Protection (Ambient Air Quality) Measure standard of 50 μg/m 3 for a 24-hour average has been adopted. This is in line with current standards for the coal industry. Table 6 Atmospheric Dust Data Month Report Received Date Published PM10 μg/m 3 24 hour average January /01/17 06/02/ February /02/17 08/03/ March /03/17 04/04/ April /04/17 05/05/ May /05/17 05/06/ June /06/17 04/07/ July /08/17 08/08/17 <0.1 August /09/17 13/10/17 <0.1 September /09/17 13/10/ Compliance summary: The February result exceeded the NEPM standard at the mine office. The corresponding deposition monitoring data at the mine office and at Medway Village was still in compliance despite the elevated PM10 reading on the mine site, and therefore deposition rates at the nearest residential receptor remain in compliance. Elevated dust readings will be expected in future as part of the earthworks component of the rehabilitation program. REPORT ENDS Page 16

Water monitoring Runoff water from the cement works and surrounding agricultural land is captured in various storage dams on site and used as process water. In heavy rain, excess stormwater from the dam called Lake Quality is allowed to overflow into the Wingecarribee River. The quality of that water is required by the licence to be monitored once per overflow event. The licence specifies the parameters to be monitored, but does not specify any limits for these parameters. Licence limits: Not specified. The NSW State guidelines: Typical discharge limits are as follows: Biological Oxygen Demand: 20 milligrams per litre ph: Oil and Grease: 10 milligrams per litre Total Suspended Solids: milligrams per litre Sampling Date Report received Date published Biological Oxygen Demand (milligrams per litre) ph Oil and Grease (milligrams per litre) Total Suspended Solids (milligrams per litre) 04/02/16 11/02/16 08/03/16 <2 8.4 < /06/16 14/06/16 08/07/16 <2 9.8 < /07/16 17/07/16 08/08/16 <2 8.5 < /08/16 02/09/16 08/09/16 <2 8.5 < /09/16 13/09/16 08/10/ < /09/16 19/09/16 08/10/16 <2 8.5 < /10/16 31/10/16 08/11/ <5 7 07/02/17 16/02/17 08/03/ < /03/17 24/03/17 08/04/17 <2 8.5 <5 34 Compliance summary: Lake Quality s overflow generally meets the typical NSW discharge criteria. Occasionally, an exceedance of ph may occur in the overflow due to alkaline nature of raw materials and products handled on site. 4. Noise monitoring

Ambient Air/Dust Monitoring Berrima Colliery has 4 dust monitoring locations as described below: Mine Office Dust Deposition (Gauge 1) Medway Village Dust Deposition (Gauge 2) Loch Catherine Coal Stockpile Dust Deposition (Gauge 3) Mine Entry Road PM 10 Atmospheric Dust (Gauge 4) 3.1 Dust Deposition Gauges: Total Insoluble Matter (grams per square metre per month) Gauges 1 to 3 are dust deposition gauges which measure the levels of coarse dust. It is a measure of dust nuisance rather than an indication of potential health problems as this dust fraction does not penetrate into the respiratory system. Licence limit: Not specified Adopted limits: For dust deposition, the NSW State guideline of 4 g/m 2 /month (presented as a 12-month rolling average) has been adopted.

45 3.2 Atmospheric Dust Sampling Berrima Colliery is required to measure the very small fraction of total suspended particulate matter, namely the 10 micron fraction (PM 10 ). This test measures the levels of the very fine dust suspended in the air which is a measure of potential health effects (irritation of the respiratory tract) as the small particles can penetrate into the airways and the lungs. Fine dust can persist in the atmosphere for days or even months before it settles and can travel some distance. Gauge 4 is located near the mine entrance which is midway between the mine facilities and the village of Medway. Licence limit: Not specified Adopted limits: For atmospheric concentration the adopted limit is 50 μg/m 3 for a 24-hour average. This is in line with current standards for the coal industry.

46 Berrima Colliery in Medway POELA Act 2011 Monitoring Data Berrima Colliery, Medway, NSW Environmental Protection Licence Number 608, held by Delta Mining Explanation of units of measure: mg/m 3 = milligrams per cubic metre g/m 2 /month = grams per square metre per month μg/m 3 = micrograms per cubic metre mg/l = milligrams per litre ML/d = megalitres per day Record updated on: 08 January Water monitoring Berrima Colliery has two licensed discharge points and four ambient background monitoring points: Discharge Points: Mine Adit - Naturally occurring groundwater is captured in the underground workings and is discharged into the Wingecarribee River. The monitoring point is referred to as the V Notch Weir Point 4). Pit Top Dam Referred to as the Chitter Dam, this dam collects water runoff from the surface facilities area. This dam did not discharge during the reporting period. Ambient background monitoring points: Wingecarribee River upstream of the mine adit discharge at Old Hume Highway Crossing at Berrima Point 9). Wingecarribee River upstream of the mine adit discharge at Macarthur s Crossing Point 10). Wingecarribee River downstream of the mine adit discharge at Biloela Camp Site Point 11). Wingecarribee River downstream of mine adit discharge at Black Bob s confluence Point 12). Ambient monitoring points provide background data for reference purposes and were added to the licence on 23 December 2013 along with additional monitoring parameters for the discharge points. The licence was amended on 9 th October The changes relate to a reduction in frequency of monitoring to two-monthly for the licensed discharge points and the ambient background monitoring locations Page 1

47 in the Wingecarribee River, as well as a reduction in the parameters required to be monitored. Licence limits for both discharge points are as follows: ph: Oil and Grease: 10 mg/l Total Suspended Solids: 50 mg/l Table 1 shows the results of parameters for Licence Point 4 for which the licence limits apply as listed above. Table 2 provides the data for the new monitoring parameters added to the Licence Point 4 while Table 3 presents new ambient water monitoring data. No concentration limits were assigned to any of these new parameters.

72 3. Ambient Air/Dust Monitoring Berrima Colliery has 4 dust monitoring locations as described below: Mine Office Dust Deposition (Gauge 1) Medway Village Dust Deposition (Gauge 2) Loch Catherine Coal Stockpile Dust Deposition (Gauge 3) Mine Entry Road PM 10 Atmospheric Dust (Gauge 4) 3.1 Dust Deposition Gauges: Total Insoluble Matter (grams per square metre per month) Gauges 1 to 3 are dust deposition gauges which measure the levels of coarse dust. It is a measure of dust nuisance rather than an indication of potential health problems as this dust fraction does not penetrate into the respiratory system. Licence limit: Not specified Adopted limits: For dust deposition, the NSW State guideline of 4 g/m 2 /month (presented as a 12-month rolling average) has been adopted.

74 3.2 Atmospheric Dust Sampling Berrima Colliery is required to measure the very small fraction of total suspended particulate matter, namely the 10 micron fraction (PM 10 ). This test measures the levels of the very fine dust suspended in the air which is a measure of potential health effects (irritation of the respiratory track) as the small particles can penetrate into the airways and the lungs. Fine dust can persist in the atmosphere for days or even months before it settles and can travel some distance. Gauge 4 is located near the mine entrance which is midway between the mine facilities and the village of Medway. Licence limit: Not specified Adopted limits: For atmospheric concentration the adopted limit is 50 μg/m 3 for a 24-hour average. This is in line with current standards for the coal industry.

75 Berrima Colliery in Medway POELA Act 2011 Monitoring Data Berrima Colliery, Medway, NSW Environmental Protection Licence Number 608, held by Delta Mining Explanation of units of measure: mg/m 3 = milligrams per cubic metre g/m 2 /month = grams per square metre per month μg/m 3 = micrograms per cubic metre mg/l = milligrams per litre ML/d = megalitres per day Record updated on: 8 January Water monitoring Berrima Colliery has two licensed discharge points and four ambient background monitoring points: Discharge Points: Mine Adit - Naturally occurring groundwater is captured in the underground workings and is discharged into the Wingecarribee River. The monitoring point is referred to as the V Notch Weir Point 4). Pit Top Dam Referred to as the Chitter Dam, this dam collects water runoff from the surface facilities area. This dam did not discharge during the reporting period. Ambient background monitoring points: Wingecarribee River upstream of the mine adit discharge at Old Hume Highway Crossing at Berrima Point 9). Wingecarribee River upstream of the mine adit discharge at Macarthur s Crossing Point 10). Wingecarribee River downstream of the mine adit discharge at Biloela Camp Site Point 11). Wingecarribee River downstream of mine adit discharge at Black Bob s confluence Point 12). Ambient monitoring points provide background data for reference purposes and were added to the licence on 23 December 2013 along with additional monitoring parameters for the discharge points.

It is a measure of dust nuisance rather than an indication of potential health problems as this dust fraction does not penetrate into the respiratory system. Licence limit: Not specified Adopted limits: For dust deposition, the NSW State guideline of 4 g/m 2 /month (presented as a 12-month rolling average) has been adopted.

106 3.2 Atmospheric Dust Sampling Berrima Colliery is required to measure the very small fraction of total suspended particulate matter, namely the 10 micron fraction (PM 10 ). This test measures the levels of the very fine dust suspended in the air which is a measure of potential health effects (irritation of the respiratory track) as the small particles can penetrate into the airways and the lungs. Fine dust can persist in the atmosphere for days or even months before it settles and can travel some distance. Gauge 4 is located near the mine entrance which is midway between the mine facilities and the village of Medway. Licence limit: Not specified Adopted limits: For atmospheric concentration the adopted limit is 50 μg/m 3 for a 24-hour average. This is in line with current standards for the coal industry.

122 Note: Quality of groundwater released from Berrima Colliery to Wingecarribee River is currently monitored under separate conditions associated with the Subsidence Management Plan approval issued by the mineral resources Authority (NSW Trade and Investment - Resources and Energy). Multiple chemical parameters including a comprehensive range of trace metals are monitored weekly at the V-notch Weir. The Colliery has not exceeded any trigger levels set up for water quality and remains within the approved limits. Publication of monitoring data that are subject to approvals other than the Environment Protection Licence is currently not required by the NSW legislation. However, summaries of this monitoring are presented by the Colliery representatives at the Community Consultation Committee Meetings. See the Meeting Minutes and Presentations displayed on this webpage. REPORT ENDS
