Typically low results during Annual Rolling Average - 12 Months to June 2018 winter and higher during spring/summer. 35 • High results at Ellis in Sep-17 due to burning off next 30 to HVAS monitor. Bushfire smoke contributed to high levels in late Sep-17. 25 PM 10 (ug/m 3 ) • High results across all monitors on 20-Mar-18 due to 20 hazy conditions across valley following a southerly 15 change and prolonged dry weather. • 10 Flat trend over previous 12 months. • HVAS results provide more reliable data compared to 5 dust deposition results and should be referred to when 0 interpreting dust emissions.

3b. Blast Management Management Area Project Status • Blast Monitoring • Blasting is scheduled to recommence at Stratford in August 2018. Blasting • The blast monitors are currently being upgraded and calibrated in preparation for installation. • Blasting Preparations • A Road Closure management plan has been prepared for closures during blasting along Wenham Cox Rd. Consultation with MCC is ongoing. • An updated blast notifications register is currently being prepared. • The blast hotline has been re-established. • Baseline condition • Notification of residents within 2kms of blasting was undertaken in April 2018. Building Inspections inspections Building inspections of residences which requested inspections have been undertaken during July 2018. 26 July 2018 7 7

3c. Noise Management Management Area Project Status • Monthly Noise Survey • Monthly attended noise monitoring commenced in July 2018. Monitoring • No non-compliant results were recorded during the survey. However, exceedances of the noise criteria were recorded at times when weather conditions were present which exclude some results. Mitigation measures are required to be implemented at times when noise enhancing weather conditions are recorded. Reports will be made available on the Stratford Coal website. The next monitoring is scheduled in August 2018. • Real-Time Noise System • A second real-time noise monitor has been installed near the Stratford village. Real-Time Noise • The integrated real-time noise management system is currently being configured. The system analyses monitoring data from the noise units, the weather station and the inversion towers and records times when either the noise criteria is likely to be exceeded or when noise enhancing weather conditions are present. The system will then provide alarms to staff to implement additional noise mitigation measures where required. 26 July 2018 8 8

3d. Water Management Management Area Project Status • Annual water balance • The annual water balance review for 2017 has been completed an is included in the Site Water Management review. SMC Annual Review 2017. • Routine monitoring • Sporadic and low rainfall conditions through Summer 2017/18 followed by a single Surface Water Monitoring large rain event in March 2018. • Routine water sampling continued. All results consistent with the SCM Environmental Assessment predictions. • Aquatic Ecology - • Scheduled in September 2018 Macroinvertebrates • Routine monitoring • Routine groundwater sampling continued. All results consistent with the SCM Groundwater Monitoring Environmental Assessment predictions. 26 July 2018 9 9

3e. Rehabilitation Management Management Area Project Status • BRN cutback visual bund • Construction and rehabilitation of the BRN Cutback visual bund along Wenham Rehabilitated Waste Emplacements Cox Road has been finalised. The visual bund was seeded in June 2018. • Vegetation Monitoring - • Rehabilitation monitoring incorporating landscape function analysis and Monitoring Ecosystem Function Analysis vegetation dynamics was undertaken in May 2018. The report is currently being finalised and a summary will be included in the Annual Review. • Fauna Monitoring • Fauna monitoring in the rehabilitation areas was undertaken during January 2018. The results found – “A total of 104 species of vertebrate were recorded, comprising 8 frogs, 10 reptiles, 56 birds and 30 mammals, most of which were native. Eight of the species detected are listed as threatened or migratory.” Photo: Brush-tailed Phascogale in established rehabilitation recorded during fauna monitoring in 26 July 2018 12 Jan 2018. 12
