8. Operators shall comply with this Article without delay and, in any case, not later than 5 February 2026 for existing sites and not later than 12 months from the date of start of operations for new sites. Where operators are unable to comply with this Article due to exceptional delay caused by the need to obtain a permit or any other administrative authorisation from the relevant authorities or the unavailability of venting or flaring equipment, they shall provide the competent authorities with a detailed implementation schedule. That schedule shall include sufficient evidence of the fulfilment of the conditions laid down in this paragraph. The competent authorities may require modifications to that schedule.
