2.0 LICENSED DISCHARGE POINT MONITORING

2.1 EPL Identification Point No. 1: Effluent Quality Monitoring Effluent quality is to be monitored on a quarterly basis. The Licence also specifies that if there is no discharge on the scheduled sampling day, a sample must be taken on the first day of discharge after the scheduled sampling day. The effluent was not discharging during quarterly sampling on 10th June, 2015. Results are presented in Appendix E – Effluent Water Monitoring.

Pollutant Unit of Measure 100 percentile

concentration limit Ammonia milligrams per litre 0.9 pH pH 6.5 – 8.5 Total suspended solids milligrams per litre 50

2.2 EPA Identification Point No. 7 & 8: Dust Monitoring One dust monitoring locations exist on the site. As per the EPA licence, the sampling and analysis of the dust gauges was conducted in accordance with AS 3580.10.1. Dust gauges were collected and replaced for monthly analysis for the period between:

• 23rd of March 2015 - 24th of April 2015 • 24th of April 2015 – 21st of May 2015 • 21st of May 2015 -18th of June 2015

The monthly dust results are included on a separate monthly report.

3.0 ENVIRONMENTAL MONITORING

3.1 EPL Identification Point No.10: Air Emissions Monitoring According to the Licence, surface methane should be measured (% by volume) on a quarterly basis. Sampling was carried out on 10th of June, 2015 using a Model Inspectra Laser All surface methane levels measured were below the specified Landfill Gas Hazard Reporting level of 1.25% methane (v/v). Results are presented in the Appendix A – Air Emissions Monitoring

3.2 Ground Water Monitoring. Licence condition M2.3 specifies that eight ground water monitoring bores (EPL Points 12, 14, 16, 17, 23, 24, 25 & 28) are to be sampled on a quarterly basis. The bores were sampled on 10th of June, 2015. All bores were analyzed for the ‘quarterly’ parameters detailed in the Appendix – Ground Water Monitoring. The attached graphs show variation of parameters with time. Results are presented in the Appendix B – Ground Water Monitoring

3.3 Surface Water Monitoring. Licence condition M2.3 specifies that three surface water-monitoring locations (EPL Points 18, 20 & 22) are to be sampled on a quarterly basis. The three locations were sampled on 10th of June, 2015 and were analyzed for the ‘quarterly’ parameters detailed in the Appendix – Surface Water and Leachate Monitoring. The attached graphs show variation of parameters with time. Results are presented in the Appendix C – Surface Water Monitoring

3.4 Leachate Monitoring Licence condition M2.3 specifies that the licensee must monitor two Leachate locations (EPL Point 21 & 26) on a quarterly basis. Sampling for the two Leachate dams was conducted on 10th of June, 2015. All leachate water was either contained on site or pumped under a Trade Waste Agreement on the day of sampling. Results are presented in the Appendix D – Leachate Monitoring
