Ash and slag waste from burning of coal (hazard class IV) is disposed of in ash disposal areas at Company facilities based on a special license. The same procedure is used to dispose of ash and slag waste from burning of coal, which is referred to hazard class V (not subject to licensing)."
2 => "The higher hazard category wastes were generated in significantly smaller volumes: I-III. Oil and petroleum product sludge in hazard class III is used as lubricants or transferred to specialised licensed providers for neutralisation (incineration)."

1 => "The Company pays special attention to the conservation and restoration of the fish stocks of rivers. Unipro assesses the impact on aquatic biological resources of those water bodies that it plans to use in its activities. Following the assessment results, certain conservation and compensation measures are taken. In particular, fish protection devices (FPD) are designed, baby fish is released."
2 => "In 2020, lake stocking was carried out at Shaturskaya GRES. In October, the branch carried out another stocking operation on the Shatursky lakes: 929 species of silver carp were released into Lake Svyatoe. Shaturskaya GRES stocks the Shatura area lakes with baby fishes every year to restore the local ecosystem. According to the established rules, the fall is the best season to stock lakes with fish, because the survival rate is relatively high. The baby fishes have been delivered to their new habitat in a special vehicle equipped with containers with oxygen frames. The place was inspected before their release. There was a check whether the artificial environment matched the natural environment, the temperature conditions and noise wave level were recorded. Baby silver carps were released to the water body by means of a special release hose."
3 => "Within the reference period the fish protection facilities were completed at PP Surgutskaya-2; fullscale tests of the actual fish protection efficiency under the program agreed with Rosrybolovstvo were started. The technical solution involved the use of a combined FPD with bottom electrodes, pontoon sections and a baffle boom."
4 => "Also in 2020, the construction of fish protection facilities was completed at Yaivinskaya GRES. The technical solution was an air bubble curtain with a floating boom."

The designers carefully calculated and justified the guaranteed fish protection efficiency of the facilities at both branches, to ensure zeropass of fish into the water-intake structures, which it will no longer be able to leave due to high speeds and flow turbulence. This was a truly fascinating and interesting engineering challenge. Now Unipro faces an equally important stage of instrumental confirmation of its effectiveness"
