Article 67 2.

The Commission may exercise the powers conferred onto it by this Regulation with respect to shipments of waste that fall under the scope of application of this Regulation pursuant to Article 2(1), which are of a complex nature and potentially have serious adverse effects on human health or the environment and where the investigation needed has a cross-border dimension involving at least two countries. The Commission may initiate actions according to these powers on its own initiative, on the request of the authorities of one or more Member States, or on a complaint if there is sufficient suspicion that the carriage of the substance or object concerned or the shipment of waste concerned constitutes an illegal shipment. The Commission may also forward such complaints to the competent authorities of the Member States concerned.
