(d) to minimise the risks associated with gases or liquids contained within the earth:
(i) appropriate controls must be applied to effectively manage these risks until the drill holes are permanently plugged or sealed in accordance with the Exploration Licence conditions;
(ii) all drill holes must be constructed so as to minimise contamination, cross-contamination and discharge of aquifers during the drilling of the hole; and
(iii) venting or flaring of gases must be conducted in a way that minimises the risk of fire, explosion and pollution.
(e) groundwater monitoring bores must be licensed in accordance with Government requirements;
(f) all drill holes which are maintained in an accessible condition must be cased to prevent collapse and fitted with a removable cap to ensure the safety of persons and fauna; and
