(c) provide such information in support of the application as is requested by the relevant authority.

4.  The relevant authority must assess the application and any information in its possession and must authorise the treatment if it is satisfied that—

9.  Where the relevant authority has informed an operator under paragraph 6 of its refusal to authorise a treatment under paragraph 4 or withdraws authorisation of a treatment under paragraph 8, the person who wishes to carry out the treatment may apply to the Agency for a review of that decision.

10.  Upon receiving the application for review, the Agency must make such inquiry into the matter as may seem to the Agency to be appropriate and, having considered the results of that enquiry and any relevant facts elicited by it, must either confirm the decision or direct the relevant authority to grant or restore, as appropriate, authorisation of the treatment process in operation. In the case of such a direction the relevant authority must thereupon comply with the said direction.
