Oct 12 (Reuters) - Russia's state-owned pipeline monopoly Transneft said on Wednesday that it expects Poland to notify it when maintenance of the Druzhba pipeline ends, after a leak was discovered on a section of the pipeline in Poland.

The Polish operator of the pipeline, PERN, said earlier that it had detected an oil leak in a section of the pipeline around 70 kilometers from the central Polish city of Plock. (Reporting by Reuters; editing by Guy Faulconbridge)
