Technologically impossible to stop the process of filling the reservoir Boguchanskaya HPP (BoHPP, Krasnoyarsk Krai) and drain all the water already typed, told RIA Novosti press-service of JSC "RusHydro".
Earlier Monday, prosecutors warned the Russian government about the possible adverse effects on the ecology of the flooded reservoir bed Boguchanskaya HPP. In particular, according to the main supervisory authority, "filling the reservoir with it growing on forest plantations will lead to its rubbish floating and sunken timber, obstruction to navigation, the emergence process of decay. Addition, reducing water exchange, temperature control will not be required to meet the breeding and feeding most fish species and negatively affect the quality of natural waters. "
"You will need to dismantle part of the concrete dam BoHPP — bottom openings through which the Angara construction period without a set of reservoirs. A total of five of them and they were closed in May 2012 after receiving authorization from the Government of the Krasnoyarsk region, responsible for the preparation of reservoir bed . These are enormous and totally pointless costs, "- said the press service of" RusHydro ".
Currently, all five bottom opening permanently concreted, the dam of the reservoir stations are under pressure. Actual depth of the reservoir at this point — more than 40 meters at the moment.
A company representative said that hydroelectric Boguchanskaya HPP is designed for use on the project around 208 meters, that is only at this level of the reservoir, the manufacturer guarantees their safe operation.
"When working at low water pressure equipment will work in non-project mode, which is not the best way affect its reliability, performance and efficiency. Thus, the absence of the project head (208 m) on the technical features of the project will prepare the nine generating units to work but will prevent them from running into a complete and safe commercial operation ", — he added.
The company is sure that in itself is not a hydroelectric environmental hazards.
"In the process of operation, hydropower produces no emissions to the atmosphere or waters of the river. Only theoretically recognized the threat to the environment of the stations can be sewage waste water and oil leaks from equipment. To store waste near the station there is a regular landfill, and to remove wastewater is to build a modern sewage treatment plant. To prevent the leakage of oil to each of the units installed drain tub, away from oil in the river, the station developed and approved "Oil Spill Response Plan", which includes organizational and technical measures to prevent environmental damage " — said the press service of "RusHydro".
He recalled that the project Boguchanskaya GES provides a number of conservation measures.
"This is a design and construction of fish protection structures for the conservation of biological resources hangars, maintenance of the water regime with providing sanitary low-water flow, which will create the right conditions for the development of aquatic life downstream from the station. After construction is supposed to complete reclamation of land used, establish systems to monitor health of watercourses and control techno-natural processes in waterworks, making it possible to monitor, prevent or minimize the impact on the environment in the future, "- he said.
BoHPP construction began in 1980, and then, after a stop in the early 1990s, reopened in 2006, JSC "RusHydro" and OK "Rusal" after agreement on a joint project to create Boguchansk Energy and Metals Association (BEMO).
Filling the reservoir BoHPP began in October 2012 and consists of two parts: to the level of 185 meters, and then to the level of 208 meters. When hydroelectric project in the flood zone reach 149.5 thousand hectares of land in the Krasnoyarsk and Irkutsk region.
