9.—(1) If, after an examination under paragraph 8 or otherwise, an eligible vehicle for which a reduced pollution certificate is in force is found no longer to satisfy the reduced pollution requirements, the authorised examiner who carried out the examination shall give notice (“a rectification notice”) to that effect to the registered keeper or the person who brought the vehicle to the examination.
(2) A rectification notice shall state in what respect the vehicle was found not to satisfy the reduced pollution requirements.
(3) A rectification notice shall state that, unless the vehicle is submitted for a further examination, at the place and within the period specified in the notice (or at such other place) or within longer period as may be agreed by the Secretary of State), and is found at that further examination to satisfy the reduced pollution requirements, the Secretary of State will at the expiration of that period revoke the reduced pollution certificate for the vehicle.
(4) Paragraphs 2(3) and 3(2) apply to an examination under sub-paragraph (3).
