For the purposes of administrative use and state supervision, the Company has developed National Standard PNST 15-2014 "Environment protection. Standards for the oil products losses in hydro turbine equipment in operation. Method for calculation of turbine oil losses while operating the hydro turbine equipment". Based on this standard, another standard GOST R (Russian National Standard) with the same name is developed.


See the texts of the standards of PJSC RusHydro at the website.


Environmental Impact Assessment


PJSC RusHydro ensures environmental safety of production activities at all stages of industrial facilities lifecycle. The measures to assess the projects’ impact on the environment (EIA) are conducted prior to the implementation of a new project or before the modification of existing facilities (at the initiation and design stages).


In accordance with the Russian law, the conduct of the EIA procedure is a prerequisite at the stage of the decision-making about the project’s implementation.


At the stage of initiating RusHydro projects, all EIA procedures are organized and conducted, including public hearings of EIA materials.


Activities to comply with the legal requirements in the field of environmental protection


RusHydro carries out its activities in compliance with the planning documentation. During the construction and operation of the facilities, the draft standards for permissible emissions and discharges of pollutants into the environment, draft regulations on waste production and limits on waste disposal, sections of planning documentation with justification of measures for biodiversity conservation are developed.


The documents are approved by the executive authorities that provide state regulation in the field of environmental protection:

  • Ministry of Natural Resources and Environment of the Russian Federation
  • Federal Service for Supervision in the Sphere of Nature Management
  • Federal Water Resources Agency
  • Federal Fishery Agency
  • Federal Supervision Agency for Customer Protection and Human Welfare On the basis of the agreed projects, permits for environmental protection required for the performance of production activities are obtained.

Impact of the RAO ES of the East on water bodies


Subsidiaries of PJSC RAO ES of the East also use water bodies for the purpose of withdrawal of water and wastewater disposal. Most of Holding’s companies do not impact significantly the water sources as total amount of water taken by the affiliates is less than 5% of the water body amount.


RAO ES of the East does not take water from water bodies classified as natural area of preferential protection. The sources providing water are not valuable from the point of view of biological diversity. An exception is water intake by JC Chukotenergo at water reservoir on Kazachka river in Anadyr – water intake amounts to 1,602.82 thousand m3 or 20.5% of the total amount of water body – 7.8 million m3.


An important project on reduction of the negative impact on water bodies is the construction of a chemical-biological treatment and sanification station for wastewater of the Khabarovskaya CHPP-2.


In 2016, the amount of repeatedly used water by RAO ES of the East increased by 7.1%.

WASTE MANAGEMENT

Production and consumer wastes are generated during the operating activities of the RusHydro Group enterprises. Primarily, there are wastes of hazard class IV and V, they are generated during reconstruction, repair works and maintenance of the equipment at facilities. The RusHydro Group companies do not transport wastes by their own efforts. Generated wastes are transferred on a contractual basis to specialized organizations that have licenses to collect and handle the wastes.

MEASURES FOR BIODIVERSITY CONSERVATION

RusHydro Group implements biodiversity conservation activities in five areas.


Activities of RusHydro Group for Biodiversity Conservation



PJSC RusHydro develops international cooperation in the field of environmental protection in regard of biodiversity conservation. In 2016, the second edition of "Compendium of innovative biodiversity solutions for the hydropower sector" was prepared with the participation of PJSC RusHydro within the project of the United Nations Development Program/Global Environment Facility and the Ministry of Natural Resources and Environment of the Russian Federation (UNDP Project). The Compendium is a practical guide for designing engineers, environmental specialists, authorities and other stakeholders for the planning of environmentally-oriented activities. The second edition of the Compendium includes the experience of PJSC RusHydro on biodiversity conservation.


Also in 2016, a specialized portal (gisamur.ru) was developed with the participation of PJSC RusHydro to ensure the solution of geo-ecological tasks for planning the development of hydropower potential in the Amur Region. This is a complex geoinformation system that allows analysing the possibilities of hydropower development taking into account environmental risks and issues of biodiversity conservation. This system can be widely used for creation of strategies and plans for the Amur region development, territorial planning, preparation of environmental passports of the subjects of the Russian Federation. The data collected on the geoportal can be used to solve many issues of state-management orientation, as well as those of industrial, scientific and educational significance.


Four years ago, the UNDP Project initiated the environmental project "Bureysky Compromise" as part of the construction of the Nizhne-Bureyskaya HPP in the Amur Region. It is implemented by the Amur Region state-financed institution "Directorate for the Protection and Exploitation of Wildlife and Specially Protected Natural Territories", JSC Nizhne-Bureyskaya HPP, scientific and environmental organizations of the region, mass media. The project is intended to demonstrate the advanced domestic and world principles of conservation of biological diversity in the implementation of large industrial facilities. In addition, the product serves as example of an effective interaction with government bodies, business and society on issues of nature conservation. The "Bureysky Compromise" project is comprehensive and includes many activities for each factor of possible negative impact of the reservoir creation on flora and fauna.


Measure on preservation of the ungulate animal population


The network of feeding stations was arranged in the depth of the Natural Park "Bureysky" in order to concentrate the animals in the centre of the Park and remove them from the construction site.


More than 25 feeding stations have been arranged in the entire territory of the Natural Park. The complexes are equipped with surveillance cameras for photo and video recording, which allows receiving information about the attendance of feeding stations by animals.


Measures on the plants preservation


Five rare and endemic plant species were found in the flood zone of the reservoir of the Nizhne-Bureyskaya HPP. In order to conserve the rare plant species their transfer to new habitats was arranged. This operation was carried out in two stages: one part of the plants was moved in 2015, an additional transfer was carried out in 2016. As a result, specialists managed to move more than 400 specimens to places suitable for growing.


An additional measure of plant support was the "ex-situ" measure in regard of the fern "Alevritopteris Kuna" listed in the Red Book, its main habitats located in the flood zone of the Nizhne-Bureya Reservoir. A specialized climatic chamber was created in the Botanical Garden of Blagoveshchensk, where from the rare fern spores the plants are grown for subsequent introduction into places suitable for growth. Bedding of plants grown in a climatic chamber will be carried out until 2019.


Preservation of the bird species


Measures to minimize the impact on the bird fauna are aimed at the two most vulnerable species: the mandarin duck and the oriental white stork.


The habitat of the mandarin duck happened to be directly into the flood zone in the area of the reservoir of the Nizhne-Bureyskaya HPP in the Amur Region.


The key habitats and natural nesting of this species were threatened with extinction. To conserve the population of the mandarin duck, about 100 artificial nest boxes have been built above the level of the reservoir design marks, mainly on tributaries. According to the monitoring results, it was established that the nest boxes began to be populated with mandarin ducks before the reservoir was filled, which confirmed the efficiency of this measure and determined the necessity to install additional artificial nest boxes. In 2016, installation of additional artificial nest boxes and the monitoring of the effectiveness of this solution was continued in order to maintain the Mandarin population in the process of a water body creation.


The south of the Amur Region is the nesting place for most of the world population of the oriental white stork. The distribution of the population of this species is in the downstream of the Nizhne-Bureyskaya HPP. In order to minimize the possible negative impact on the population of the oriental white stork, the artificial nest supports were installed with the support from UNDP Project.


The nests can hold up the weight of the stork. In 2017, it is planned to install artificial nest supports for the oriental white storks in the Muravievsky Nature Reserve, as the Amur regional public environmental organization "AmurSoES" and the regional "Directorate for the Protection and Exploitation of Wildlife and Specially Protected Natural Territories" filed a request to the energy sector.


Moreover, according to the information of the Amur regional public ecological organization "AmurSoES", in 2016, there were about 100 inhabited nests of oriental white storks in the southern regions of the Amur Region, and more than 40% of them were located on the supports of overhead transmission lines.


The PJSC Yakutskenergo (subsidiary of RAO ES of the East) equips the high-voltage power transmission lines passing through a specially protected natural territory in Ust-Maysky ulus in Yakutia with special bird protection devices. 24 species of birds are protected there.


Also, PJSC Yakutskenergo provides isolation of the power transmission lines with a special cable SIP in the territory of the Natural Park "Living Diamonds of Yakutia", where the high-voltage transmission line 6-10 kW passes through. In addition, the company equips transformer substations on transmission lines with fences and covers to prevent animals from entering into the substation and into the mechanisms of the substation.


Restoration of the fish resources


Due to the specifics of the Company's activity, the RusHydro pays a special attention at the conservation and restoration of fish resources of rivers. For this purpose, since 2003, the annual voluntary planting of fish actions has been taking place at the rivers and reservoirs of HPPs.


In 2016, the Kabardino-Balkarian branch of PJSC RusHydro together with the West Caspian Territorial Administration of the Federal Agency for Fishery released 43 thousand fries of the Russian sturgeon and 71 thousand fries of the Caspian salmon into the Terek River and its tributaries on the territory of the Republic of Dagestan and the Cherek River and the White River in Kabardino-Balkaria.


The companies of RAO ES of the East also implement measures for the artificial reproduction of aquatic biological resources. For example, the Bystrinskaya Small HPP produces an annual release of fry in the rivers of the Kamchatka Region.


Support of protected natural areas


In 2009, an active work to preserve the population of the Caucasian bison listed in the Red Book of the Russian Federation and IUCN began in the North Caucasus.


In 2016, with the support of PJSC RusHydro, a specialized open-air cage with an area of 5 hectares for individuals of the Caucasian bison was built on the territory of the Tourmonsky Nature Reserve in the Republic of North Ossetia-Alania. Open-air cage allows to perform the primary acclimatization of animals grown in captivity for subsequent release into the natural habitat in the territory of the North Ossetian State Nature Reserve.


PJSC RusHydro became sponsor of the international program to restore the population of this endangered species. The cost of financial assistance of PJSC RusHydro in the opening of the open-air cage was about 300 thousand roubles.
