19 Criteria for draft site plans—Part A

(1) Part A of the draft site plan must: (a) be presented as “Part A—Behaviours predicted for the purposes of paragraphs 379(1)(e) and (f) of the Act”; and (b) 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 formation; and (c) include information relevant to the predictions.

Note: For paragraph (a), section 379 of the Act deals with when a serious situation exists in relation to an identified greenhouse gas storage formation.

(2) For the purposes of paragraph (1)(b) of this section: (a) the specified times must be of a sufficient number, and be at sufficiently frequent intervals, to ensure that: (i) the predictions are soundly based; and (ii) comparison of the actual and predicted behaviours of each substance will enable the timely detection of the existence of serious situations mentioned in paragraphs 379(1)(e) and (f) of the Act in relation to the formation; and (b) the predictions must be set out and explained in sufficient detail to demonstrate that the predictions are soundly based; and (c) the predictions must be consistent with the spatial extent of the formation (as declared under paragraph 312(11)(d) or 312A(11)(d) (as applicable) of the Act); and (d) the predictions for the behaviour of a substance must be described by reference to the following: (i) each known or expected migration pathway of the substance; (ii) each known or expected migration rate of the substance; (iii) any other matter relevant to the accuracy of the predictions; and (e) the predictions must demonstrate that the behaviour of each substance will be consistent with the formation being safe and secure for the permanent storage of: (i) any substances that are already stored in the formation; and (ii) the substances that are proposed to be injected into and stored in the formation; assuming that the predicted behaviour occurs at the times at which it is predicted to occur. (3) For the purposes of paragraph (1)(c) of this section, the information must include the following: (a) the information that was included in the application (including the application as varied) for the declaration under section 312 or 312A (as applicable) of the Act in relation to the formation in accordance with clause 3 (integrity of the formation) and Part 3 (estimates of spatial extent) of Schedule 1 to this instrument; (b) if a variation of the declaration under section 312 or 312A (as applicable) of the Act in relation to the formation has been made on application as mentioned in paragraph 313(3)(a) of the Act—the information relating to the integrity of the formation and the estimate of the spatial extent of the formation that was included in the application.
