(1) Where a monitoring methodology plan has an installation under Article 8 of the Free Allocation Regulation, the regulator may, by notice to the registry administrator, require the registry administrator to withhold allowances that would otherwise have been allocated in respect of the installation under article 34E.

(2) Where a notice under paragraph (1) is given, no allowances may be allocated in respect of the installation set out in the notice until the regulator gives a further notice to the registry administrator, which must be given as soon as reasonably practicable after a monitoring methodology plan is approved.
