3. Where a Member State requests to postpone the deadline laid down in paragraph 1, point (d), of this Article the Commission may, within 3 months of receipt of the implementation plan submitted pursuant to paragraph 2, point (d), of this Article request the Member State to revise the plan if the Commission considers that the plan does not comply with the requirements set out in Annex XI. The Member State shall submit a revised implementation plan within 3 months of receipt of the Commission’s request. If the Commission considers that the revised implementation plan does not comply with the requirements set out in Annex XI and that it is unlikely that the Member State will be able to meet the targets within the period of postponement pursuant to paragraph 2 of this Article, the Commission shall reject the implementation plan and the Member State shall be obliged to comply with the targets within the deadlines set in paragraph 1, point (d), of this Article.
