Tainted Russian oil has been fully removed from the Unecha-Polotsk oil pipeline. Now that this phase is over, the transportation of standard-quality oil to Naftan oil refinery via two branches of the Unecha-Polotsk oil pipeline will commence. Work to clean the Belarusian section of the Surgut-Polotsk oil pipeline by mid-August continues. Over a million tons of Russian tainted oil mixture reached Belarus.
