Section E – Details of Non-Compliance with Licence Condition
Please use a separate page for each condition with which the licence holder was non-compliant at a time during the reporting period.
Condition no:
1.2.1
The Licensee shall operate all pollution control and monitoring equipment to the manufacturers specification or any relevant and effective internal management system.
Date(s) of non- compliance:
Variable across the reporting period.
Details of non-compliance:
Pollution control equipment that was a) not operational, b) failed or c) was not maintained to the standard as intended by this condition includes:
Dust Scrubbers within the processing plant;
o Dust Scrubbers within the crushing circuit of the processing plant experienced a delayed return to service following equipment failure during the reporting period.
Process Water Pond liner;
o Groundwater monitoring results from a monitoring bore immediately adjacent to the Process Water Pond indicate that the integrity of the HDPE liner on the Process Water Pond to be potentially compromised.
The groundwater monitoring bore adjacent to the Process Water Pond recorded a maximum result of 0.024 mg/L WAD Cyanide during the reporting period.
Tailings Storage Facility liner;
o The operation of the TSF has been observed to have a localised impact to groundwater quality and groundwater levels during the reporting period.

What was the actual (or suspected) environmental impact of the non-compliance?
NOTE – please attach maps or diagrams to provide insight into the precise location of where the non- compliance took place.
DUST SCRUBBERS
Due to the physical location of this infrastructure within the broader disturbed footprint, there has been no observable impact to any environmental receptors, including vegetation.
4
Annual Audit Compliance Report Form (September 2018)
PROCESS WATER POND LINER
Localised detection of very low levels of WAD Cyanide in the groundwater environment are not anticipated to have any detrimental impact on the existing saline to hypersaline groundwater regime. There is no known beneficial users of the groundwater in the vicinity of the TGM operation.
5
Annual Audit Compliance Report Form (September 2018)
TAILINGS STORAGE FACILITY
Localised changes in groundwater quality are not considered to have had any detrimental impact to environmental values. The existing groundwater environment is typically saline to hypersaline and has no known beneficial users.
Groundwater levels surrounding the TSF were observed to rise during the reporting period.
Increases in groundwater level were not observed to have any impacts on environmental receptors, including vegetation.
o Monitoring of vegetation condition in proximity to operational areas has not identified any impacts to vegetation health associated with changes in groundwater quality or groundwater levels.
Cause (or suspected cause) of non-compliance:
DUST SCRUBBERS
The spare parts held on site were not correct and there was a delay in sourcing the correct components.
PROCESS WATER POND LINER
Suspected failure in the integrity of both the primary and secondary HDPE pond liners in specific areas of the Process Water Pond.
6
Annual Audit Compliance Report Form (September 2018)
TAILINGS STORAGE FACILITY
The cause/s of the localised change in groundwater levels and quality from the TSF have not yet been determined and are subject to ongoing monitoring investigation.
Action taken to mitigate any adverse effects of non-compliance and prevent recurrence of the non-compliance:
DUST SCRUBBERS
Actions to be undertaken are:
Review Planned Maintenance tasks for Dust Scrubbers to improve reliability and asset integrity.
Review onsite holdings of critical spares for Dust Scrubber components.
PROCESS WATER POND LINER Actions to be undertaken are:
During a planned maintenance shutdown in 2019, the Process Water Pond liner integrity will be inspected and any identified damage repaired and/or a maintenance plan developed to action remedial repairs in a timely manner.
TAILINGS STORAGE FACILITY Actions completed include:
Groundwater monitoring of water levels and water quality around the TSF.
Implementation of a Seepage Mitigation Project to install recovery bores in target areas around the perimeter of the TSF.
Actions to be undertaken include:
Continued groundwater monitoring of water levels and water quality around the TSF.
Install additional recovery bores as required.
Development of a Seepage Management Plan.

Annual Audit Compliance Report Form (September 2018)
Condition no:
1.3.2
The licensee shall ensure that waste produced on the premises are only subjected to the processes set out in Table 1.3.1 and in
accordance with any process limits described in that table.
Date(s) of non- compliance:
Various times throughout the reporting period.
Details of non-compliance:
During the reporting period routine workplace inspections identified that package waste hydrocarbons were, on occasion, temporarily stored outside of appropriately bunded areas. No release of hydrocarbons to the receiving environment occurred as a result of the temporary non-compliance.
What was the actual (or suspected) environmental impact of the non-compliance?
NOTE – please attach maps or diagrams to provide insight into the precise location of where the non- compliance took place.
No detrimental impact to the environment has occurred as a result of the incorrect storage of packaged waste hydrocarbons.
Cause (or suspected cause) of non-compliance:
Inconsistent application of bunding for packaged waste hydrocarbons across site.
Action taken to mitigate any adverse effects of non-compliance and prevent recurrence of the non-compliance:
Routine workplace inspections are undertaken and if a non-conformance in waste hydrocarbon storage is identified, corrective actions are assigned in the TGM Event Management System.

Condition no:
1.3.6
The licensee shall ensure that tailings, decant water, process plant storm water and waste water treatment plant (WWTP) effluent are only discharged into
containment cells with the relevant infrastructure requirements and at the locations specified in Table 1.3.3.
Date(s) of non- compliance:
Various times throughout the reporting period.
Details of non-compliance:
Throughout the reporting period the following containment devices did not sufficiently contain the material as required by Condition 1.3.6:
Process Water Pond liner;
o Groundwater monitoring results from a monitoring bore immediately adjacent to the Process Water Pond indicate that the integrity of the HDPE liner on the Process Water Pond to be potentially compromised.
The groundwater monitoring bore adjacent to the Process Water Pond recorded a maximum result of 0.024 mg/L WAD Cyanide during the reporting period.
