The fly ash precipitator refurbishment project is ongoing. IMPLEMENT LARGE-SCALE ASH AND SLAG WASTE UTILISATION INITIATIVES according to the plan of LLC Baikal Energy Company. DEVELOP PROJECT DOCUMENTATION FOR THE BRANCHES OF LLC EUROSIBENERGO- HYDROGENERATION to ensure the organised collection, treatment, and disposal of surface and drainage wastewater from HPPs, and to equip drainage systems with local wastewater treatment systems. Draft materials for a preliminary feasibility study for similar projects at Krasnoyarsk HPP. The project for using the wastes for mines restoration/land habitation is on the Environmental examination stage. After the examination it will be decided how to scale up this practice. A second project concerns the use of waste as a component in road construction. In 2021, the appropriate R&D has been started. 150 metres of roadbed near Irkutsk has been constructed by using fly and bottom ash. The monitoring of road conditions was started in autumn of 2021 and will continue in the first half of 2022 to assess the use of fly and bottom ash in road construction. The project documentation stage for wastewater treatment facilities was started in 2021 at Bratsk, Ust-Ilimsk and Irkutsk HPPs. The pre-preliminary examination for wastewater treatment facilities at Krasnoyarsk HPP has been completed. En+ Group takes a responsible approach to the use of natural resources and applies the precautionary principle in its risk management system and when evaluating environmental impacts to minimise the adverse consequences of its activities. The Company uses innovative high-tech solutions that allow us to combine the minimisation of environmental impacts with optimisation of the production process. The key aspects of the Company's environmental protection activities are: • Identifying and assessing the environmental and climate aspects and risks generated by the Company's facilities, as well as the impact of environmental and climate risks on the Company's activities Complying with environmental legislation in the regions where the Group operates, as well as with internal corporate regulations and industry best practice, which can be more tough than local regulations Preventing and mitigating environmental and climate impacts Restoring of territories and offsetting the residual impacts on ecosystems from operational activity Engaging with stakeholders and respecting their views In line with its environmental policy, the Company is constantly improving the existing environmental management system to comply with ISO 14001, the international standard on environmental management systems, and GOST R 14001-2016, the Russian national standard on environmental management systems. In 2021, the ISO 14001 implementation project has been completed at LLC EuroSibEnergo-Hydrogeneration including the Bratsk, Irkutsk, and Ust-Ilimsk HPPs. The environmental management system is ready for certification. In 2021, the supervisory authorities carried out inspections of the Company's enterprises. No significant environmental fines or incidents (exceeding USD 1 million) were reported. Work is underway to remedy all recorded minor incidents. We take a responsible approach to air quality issues in regions of operation All of the Company's facilities, without exception, comply with the requirements of environmental legislation. Despite this, En+ Group is constantly striving to improve its environmental performance by implementing measures and initiatives aimed at reducing emissions of pollutants into the atmosphere. As part of its responsible approach to air quality issues in its regions of operation, En+ Group has been taking an active part in the implementation of the Environmental National Project and Clean Air Federal Programme since 2018. The goal of this programme is to significantly improve air quality in 12 industrial Russian cities, including Bratsk, Novokuznetsk, and Krasnoyarsk - cities where En+ Group operates. According to the plan, the reduction in emissions should reach 20% of the volume of the 2017 base year by 2024, and automatic continuous emissions measurement systems should be installed. The Company's facilities located in the cities affected by the programme are taking various measures to reduce the volume of emissions of pollutants released into the atmosphere. Enterprises of the Metals segment are implementing a list of measures aimed at improving air quality in the regions of operation, including: . • • • Monitoring atmospheric conditions through automatic continuous emissions measurement systems and mobile laboratories Using modern gas treatment facilities, including units engineered by RUSAL's design and scientific departments Conducting R&D activities and implementing the results Applying Eco-Søderberg technology (at the Krasnoyarsk, Bratsk, Irkutsk, and Novokuznetsk aluminium smelters) Using best available technologies to reduce air emissions Refurbishing aluminium smelters The main emissions of the Power segment are associated primarily with the combustion of fossil fuels for energy generation. One of the ways to reduce the volume of pollutant emissions into the atmosphere is to increase the efficiency of generation at the Company's facilities. Baikal Energy Company LLC is continuing to upgrade the electrostatic precipitators at the Novo-Irkutsk CHP and the Novo-Ziminskaya CHP, and replacing fly ash traps with modern electrostatic precipitators at CHP-6 and UICHP to reduce the pollutant output. We comply with the limits on water withdrawal from water bodies and wastewater discharge The majority of water usage at Company sites relates to the alumina facilities of the Metals segment and the power generation facilities in the Power segment. All enterprises of En+ Group comply with the limits on water withdrawal from water bodies and wastewater discharge; no significant violations of legal requirements were recorded in the reporting period. Most of the enterprises are located in regions that are not classified as water scarce. The Company's activities in the field of water management include: • Reducing the volume of fresh water used in operational processes Reducing the volume of wastewater produced and the concentration of hazardous substances contained therein Increasing the quantity and quality of • Increasing water recycling ° wastewater treatment processes Water quality monitoring 2 3 回 82 83
