Justification for changes described in Table 11 are as follows: ∕ Updating the maximum volume of Sandstone Gully TSF, as justified in Section 2.2.3; ∕ Removing reference to “Cyanide” as referencing “Tailings” is sufficient to the purposes of describing the regulated structure; and ∕ Inclusion of the Upper Mundic Gully TSF in Table H2 is required to authorise the consequence category, maximum surface area, maximum volume and purpose.
