Petroleum and Greenhouse Gas Storage (Submerged Lands) (Greenhouse Gas Injection and Storage) Regulations 2026

Part A of a draft site plan must —

be presented as “Part A — Behaviours predicted for the purposes of section 74AJ(c) of the Act”; and

set out predictions for the behaviour, at specified times, of each greenhouse gas substance that is already stored in, or is proposed to be injected into and stored in, the identified GHG storage formation; and

include information relevant to the predictions.

For the purposes of subregulation (1)(b) —

the specified times must be of a sufficient number, and be at sufficiently frequent intervals, to ensure that —

the predictions have been arrived at on a sound basis; and

the comparison of the actual and predicted behaviours of each substance will enable the timely detection of the existence of a serious situation mentioned in section 74AJ(c) of the Act in relation to the identified GHG storage formation;

the predictions must be set out and explained in sufficient detail to demonstrate that the predictions have been arrived at on a sound basis; and

the predictions must be consistent with the estimated spatial extent of the formation (as declared under section 74AE(3)(a) of the Act); and

the predictions for the behaviour of a substance must be described by reference to the following —

each known or expected migration pathway of the substance;

each known or expected migration rate of the substance;

any other matter relevant to the accuracy of the predictions;

the predictions must demonstrate that the behaviour of each substance, if it were to occur at the times at which it is predicted to occur, would be consistent with the formation being safe and secure for the permanent storage of —

any substances that are already stored in the formation; and

the substances that are proposed to be injected into and stored in the formation.

For the purposes of subregulation (1)(c), the information must include —

the information that was included in the application for the declaration under section 74AB of the Act in relation to the identified GHG storage formation in accordance with clause 3 and Division 3 of Schedule 1; and

if a variation of the declaration under section 74AE of the Act has been made under section 74AG of the Act — the information in relation to the identified GHG storage formation in accordance with clause 3 and Division 3 of Schedule 1 that was included in the variation application.
