Reduction of pollutant emissions

In accordance with EU regulations, and in particular Directive 2010/75/EU of the European Parliament and of the Council of 24 November 2010 on industrial emissions (integrated pollution prevention and control) (the Industrial Emissions Directive or IED), as of 1 January 2016 new, stricter environment protection standards are applicable. Therefore, all electricity producers in Poland who use first of all carbon-intensive technologies are obliged to adjust their power units to the new environmental requirements. To address the problems of entrepreneurs, EU law envisages a possibility of using derogation mechanisms. The alleviation of the IED requirements in the form of a derogation makes it possible to obtain additional time for adjusting generation units to the stricter air pollutant emission standards. On 17 August 2017, the so-called BAT conclusions for large combustion plants (Commission Implementing Decision (EU) 2017/1442 of 31 July 2017 laying down the conclusions on best available techniques (the BAT conclusions) for large combustion plants in accordance with Directive 2010/75/EU of the European Parliament and of the Council) were published in the Official Journal of the European Union. The published BAT conclusions introduce, among other things, stricter requirements (than in the IED) for pollutants such as sulphur dioxide, nitrogen oxides and dust. The BAT-associated emission levels (BAT-AELs) were also determined for additional substances such as mercury, hydrogen chloride, hydrogen fluoride and ammonia. The BAT conclusions will apply from 18 August 2021 after the end of the 4-year adjustment period.

Pursuant to the regulation of the Minister of Environment of 1 March 2018 on emission standards for certain installation types, fuel combustion sources and waste combustion or co-combustion installations (Polish Journal of Laws of 2018, item 680), in relation to Unit 11 for emission of all pollutants and in relation to Units 1-10 for NO_x emissions, the following conditions for the compliance with the emissions standards apply:
a) a) none of the approved average monthly concentrations of substances exceeds 100% of the emission standard,
b) none of the approved average daily concentrations of substances exceeds 110% of the emission standard,
c) 95% of all approved average hourly concentrations of substances during the calendar year does not exceed 200% of the emission standard.
If even one of the conditions specified in items a), b), c) is not met, there is a risk that a penalty will be imposed for each hourly exceedance counted from the beginning of the year.

In 2019, there were no violations of formal and legal requirements.

Kozienice Power Plant meets the objectives set by the national and community law (IED directive, BAT conclusion). The power plant operates five flue gas desulphurisation (FDG) installations, which guarantee the required reduction of SO₂ emissions from flue gases of all units. All units of the power plant are equipped with highly efficient electrostatic precipitators, which are upgraded on an ongoing basis in order to maintain high dust removal efficiency. All units (excluding Unit 3) are also equipped with selective catalytic NOx reduction (SCR) installations.

Issues regarding the Mining Area – LW Bogdanka

Land reclamation

in 2019, reclamation works were completed in the areas affected by mining damage in Nadrybie Wieś. The works consisted in making a fish pond and elevating the area using mining waste, covering it with earth masses and afforestation. The works were completed in August 2019
maintenance of organised greenery, a waste disposal facility and post-industrial areas in the area of Pole Bogdanka, Nadrybie and Stefanów reclaimed in previous years, as well as railway facilities in Zawadowo is carried out on an ongoing basis

Surface protection

the impact of mining operation conducted in 2019 on the surface was manifested, just as in the previous years, mainly through the expansion of the surface area of the impact exerted so far
the maximum subsidence in the “Puchaczów V” mining area remains in the area of Bogdanka and Nadrybie Wieś villages, commune Puchaczów and amounts to ca. 5.0 m in the central part of the subsidence trough in this region
just as it the previous years, the damage to buildings in 2019 was caused mainly in rural buildings, whereby the reported damage to buildings did not cause any hazard to users and was repaired on an ongoing basis
in 2019, works were carried out in connection with drainage of agricultural land on mining damage by rebuilding the drainage network and building a pumping station with compensating reservoirs.

Sanctions and fees which may be imposed on the Company for environmental protection purposes

mining activity involves the payment of operation fee, the fee for using the natural environment, and various other costs related to:
- mining waste management
- reclamation of industrial waste land,
- environmental monitoring,
- preparing the land surveys and documentation necessary for the proper operation of the facility,
the operation fees are paid every 6 months to the bank accounts of the municipalities where the operation is carried out (60%) and to the National Environmental Protection and Water Management Fund (NFOŚiGW) (40%)
LW Bogdanka S.A. meets the standards in the field of environmental protection and was not required to pay any penalties for violating the conditions of using the environment set out in applicable legal regulations in 2019.

Air protection

LW Bogdanka S.A. does not have any arranged emitter emitting dust and gases to the air
a non-arranged emitter is the extraction waste neutralisation plant at Bogdanka which may be the source of dusting on dry and windy days
fugitive air emissions come from combustion of fuels in combustion engines used in the company, from combustion processes and from refrigerant replenishment in air conditioners

Water and waste water management

Refers mainly to mine water, including:

rock mass drainage in the area of mine workingsdrenowania górotworu w obrębie wyrobisk górniczych
re-use of water for fire protection and process purposes
pumping water to the Surface
mine water retention in a surface reservoir and sedimentation tank for the purpose of suspended solids reduction
water discharge from the reservoir through a system of drainage ditches and Rów Żelazny watercourse to Świnka river in the amount of approx. 14,738 m³/24 hours
mine waters are characterised by the total contents of chlorides and sulphates in the amount of 1,075 mg/dm³
re-use of mine water (Zakład Przeróbki Mechanicznej Węgla, Łęczyńska Energetyka Sp. z o.o. – part of the Water Treatment Station)

Waste management:

in 2019, the total increase in mining waste was 6,299.9 thousand tonnes
approx. 49% of waste was subject to recycling and management. The amount of recycled waste, i.e., waste used for industrial waste land reclamation, road and yard hardening, cement production at “Ożarów” Cement Production Plant, and for other purposes, was 3,061.8 thousand tonnes
47% of waste is used to perform reclamation of industrial waste land. Reclamation consists in restoring the original relief of such land through filling sand pits with mining waste, covering them with a layer of soil and its agricultural or forest development
other extraction waste (3,238.1 thousand tonnes) is stored in the extraction waste neutralisation facility in Bogdanka
LW Bogdanka S.A. manages other industrial waste: it releases to the licenced entities any waste which is capable of reuse (timber, used oils, scrap metal, scrap conveyor belts) or intended for neutralisation (used light sources, glue and paint packaging, etc.)
