6. In addition to the conditions set out in paragraphs 2 and 3, flaring shall be allowed only where either re-injection, utilisation on-site, storage for later use or dispatch of methane to a market are not feasible for reasons other than economic considerations. In such a situation, as part of the reporting obligations set out in Article 16, operators shall demonstrate to the competent authorities the necessity to use flaring instead of either re-injection, utilisation on-site, storage for later use or dispatch of methane to a market.
