In deciding whether to approve the proposed amendment the Minister must consider--
(a) the development plan criteria; and
(b) the extent to which the current development plan for the GHG lease has been complied with; and
(c) if the proposed plan provides for a significant change that is a reduction of GHG stream injection--
(i) whether the reduction is reasonable; and
(ii) whether the GHG lease holder has taken all reasonable steps to prevent the reduction.
