Information request
ii.
Describe the results of leachate testing to determine the potential for contaminants to leach into groundwater. Potential impacts on ecological systems and groundwater environmental values.
iii.
d) Identify and describe all seepage pathways and flows from the UGM TSF including the receiving receptors.
e) Provide a seepage management plan which includes:
i.
Design specifications to mitigate or manage potential flows through the facility, including evidence of the liner's ability to withstand the hydraulic pressure from the high liquid content and storage of water under extreme climatic events, and prevent seepage.
ii.
Proposed measures to minimise seepage, including monitoring and maintenance strategies.
iii.
Contingency measures in the event of seepage detection.
f) Describe in detail the potential impacts due to the proposed activity and all associated risks to the groundwater environmental values in consideration of the above requested information. Consideration must be given on whether the identified impact on receiving waters supports the management intent for those waters, to the extent practicable. g) Describe in detail the strategies to mitigate and manage the identified risks to groundwater environmental values. For example:
i.
The locations, depths and purpose of the monitoring bores.
ii.
Frequency and parameters for groundwater quality and level monitoring.
h) Submit a long-term groundwater monitoring plan for the UGM TSF, including post-closure monitoring requirements and measures to
