RESULTS OF 2023
Atmospheric air protection
According to the results of 2023, the volume of gross air emissions remained flat with 2022 indicators because of inventory of air emission sources and establishment of standards for maximum permissible air emissions.The Company engaged accredited laboratories to control the volume of air emissions in 2023. The test results did not show any above-limit values.
2023 activities and events:
- Laboratory and instrumental control of air emissions at sources under contracts with accredited laboratories. The control results did not show any above-limit values
- Development of industrial environmental control programmes
- Development of measures to reduce emissions of harmful (polluting) substances into the atmospheric air during periods of unfavourable meteorological conditions
- Development of sanitary protection zone projects for production sites, measures on observation programme at the boundaries of sanitary protection zones
- Monitoring of carbon monoxide content in vehicle exhaust gases and timely repair of vehicles
- Improvement of operational activities and repair production technology (by the enterprise)
- Use of certified fuels
- Formation of statistical observation data on atmospheric air protection
- Generation of reports on industrial environmental control programmes at production sites of branches
Protection and rational use of water resources
In order to protect and rationally use water resources under licence agreements, groundwater quality assessment was carried out in 2023 (observation of groundwater level and temperature, recording of water consumption, sampling for bacteriological and chemical analysis, determination of physical properties of water).
2023 activities and events:
- Transfer of wastewater to specialised enterprises for treatment. To control the composition and properties of wastewater, submission of a declaration to MUE Vodokanal on the composition and properties of wastewater discharged by the subscriber into the wastewater disposal system during 2023
- Laboratory control of wastewater quality
- Well abandonment and licence cancellation in the Volgograd Region
- Development of a suspension project for a water intake well in the Rostov Region
- Groundwater monitoring in accordance with the programmes developed and registered with the subsoil assets manager for Volgogradenergo and Rostovenergo branches
Waste management
Indicators | 2021 | 2022 | 2023 | Change 2023/2022, % |
|---|---|---|---|---|
Volume of generated waste, tonnes | 5,991.339 | 7,172.023 | 6,826.870 | –4.810 |
Volume of waste transferred for disposal and treatment, tonnes | 3,994.560 | 4,625.968 | 4,852.450 | 4.900 |
At all production sites, waste is accumulated in places arranged in accordance with the requirements of environmental protection legislation and legislation on ensuring the sanitary and epidemiological well-being of the population, with a view to its further transfer to specialised organisations.
In order to protect and rationally use land, the Company organised regular control over separate accumulation of municipal and industrial waste (waste tyres, transformers, batteries, mercury-containing lamps, oils, metal waste, etc.), their timely transfer to specialised organisations for treatment and disposal. In 2023, 237 condensers containing
2023 activities and events:
- Timely removal of industrial and solid municipal waste by specialised organisations
- Generation of statistical observation data on generation, use, treatment, transportation and disposal of production and consumption waste
- Maintenance of records of waste generation and movement
- Control over separate accumulation of industrial waste (waste tyres, scrap metal, waste transformers, batteries, mercury-containing lamps that have lost their consumer properties, waste oil, etc.) and solid municipal waste in places specially designed and equipped for accumulation of waste of a certain type
Ecosystem and biological diversity conservation
Overhead power lines and open switchgear of substations of different voltage classes pose a potential threat to birds. Birds using overhead lines and substation equipment at various stages of their life cycle can cause damage and outages to overhead transmission lines and substations, resulting in damage to equipment and birds being exposed to risks of mortality. The Company ensures the required level of ornithological safety at power grid facilities and, consequently, the required level of power supply reliability, which is achieved through the use of various types of bird diverters.
Main objectives of the Company in the field of environmental safety for 2024:
- Provision and monitoring of a safe level of pollutant atmospheric emissions from stationary sources
- Sanitary and hygienic control at the boundaries of sanitary protection zones
- Personnel upskilling in environmental protection
- Installation of pedestal-mounted bird diverters in birds habitation and migration areas
- Elimination of waste accumulation periods at production sites, timely removal of waste from the territory of production sites, fulfilment of the schedule for decommissioning of PCB-containing equipment and its delivery for destruction for
2023–2024 - Compliance with subsoil license agreements
