(2) Where an application for the registration of an old mining permission has been granted, any person who is an owner of any land to which the permission relates, or is entitled to an interest in a mineral to which the permission relates, may apply to the planning authority to determine the conditions to which the permission is to be subject. (3) The application must set out proposed conditions. (4) The application must be served on the planning authority— (a) after the date mentioned in sub-paragraph (5), and (b) except where paragraph 10(3) applies, before the end of the period of 12 months beginning with that date or such extended period as may at any time be agreed upon in writing between the applicant and the authority. (5) The date referred to in sub-paragraph (4) is— (a) the date on which the application for registration is granted by the planning authority, if no appeal is made to the Secretary of State under paragraph 17, and (b) in any other case, the date on which the application for registration is finally determined. (6) On an application under this paragraph— (a) the planning authority must determine the conditions to which the permission is to be subject, and (b) if, within the period of 3 months beginning with the service of notice of the application (or within such extended period as may at any time be agreed upon in writing between the applicant and the authority) the authority have not given the applicant notice of their determination, the authority shall be treated for the purposes of paragraph 10 and this Part of this Schedule as having determined that the permission is to be subject to the conditions set out in the application. (7) The condition to which an old mining permission is to be subject by reason of sub-paragraph (1)(c) is not to be regarded for the purposes of the planning Acts as a condition such as is mentioned in section 41(1)(b) (planning permission granted for a limited period).
