The supply of low-quality raw materials through the Unecha-Polotsk pipeline was stopped on time. The contaminated oil was sent to the reservoir park of the Polotsk-Transneft Druzhba enterprise. Now, according to preliminary estimates, there are more than 400 thousand tons of low-quality raw materials in the system of main oil pipelines. The local authorities of Novopolotsk are concerned about the situation. Naftan is a city-forming enterprise that forms 90 percent of the city’s economy.
