INDUSTRIAL SAFETY *ORENBURG LOCAL GOVERNMENT

On August, 19th, 2005 in Oktabrskoe village in the result of not authorized cutting in the Orenburg - Salavat - Ufa (77 km) condensate line there was an emergency emission of gas condensate. About 145 m3 of gas condensate has been thrown out to the atmosphere. The major part of the pollution got into Gumbet river. The adjoining territory - inundated meadows undergone the pollution, the pollution has extended to more than 5 km.

Due to the operative actions of the Orenburg militarized unit of the "Orenburggazprom" Open Company and the experts from UESP "Orenburggazprom" Open Company the condensate outflow has been eliminated and were quickly undertaken the prime actions on localization and collecting of the condensate.

The experts of the "Orenburggazprom" Open Company, UESPand the scientific and technological centre "Prombezopasnost- Orenburg" accepted a decision to use the biological method of additional cleaning of the polluted remote territory. For the best results special actions have been taken: the natural microflora was preliminary activated by entering humin substances and massive stage-by-stage processing of the polluted territory by the activated biological product DEVOROIL. The biological product was preliminary activated by continuous aeration in the water environment at presence of biogenic additives for restoration of the microorganisms*activity.

4 processing stages were conducted each with 6-10 days break. For acceleration of the condensate pollution oxidation process the doze of the preparation and biogenic additives has been increased in 2,5 times. Results of visual inspection of the territory showed that in 4 days there appeared the attributes of active destruction of the condensate film. In 12-16 days the condensate film was almost completely destroyed. Active growth of seaweed was marked at the former polluted territory.

The chemical-analytical control has shown that reduction efficiency of oil products dissolved in water has exceeded 90 %.

Now we keep working with the additional cleaning of the territory.
