Lithuania tightens up air pollution requirements for medium combustion plants


Lithuania is tightening up the air pollution requirements for medium combustion plants. This is provided for in the Standards for emissions of pollutants from medium combustion plants approved by Minister of Environment Kęstutis Navickas that came into force on 22 September last Friday. They will apply to such plants regardless of the fuels used in them.

According to Eugenijus Leonavičius, chief specialist of the Ambient Air Division of the Pollution Prevention Department at the Ministry of Environment, in our country the majority of these plants includes boiler houses that supply heat to separate urban areas and towns. They often become the greatest air polluters in their respective locations. The operation of such plants in Lithuania has been regulated for more than 20 years already. Their operation requires compliance with the limit values for emissions of sulphur dioxide, nitrogen oxide, particulate matter and carbon monoxide set forth in the Standards for emissions of pollutants from medium combustion plants, and the accounting of fuel used and emissions of pollutants. Most of these plants can only be operated with a pollution permit granted under the prescribed procedure.

The new requirements will come into force as follows: in 2025 for plants with a rated thermal input of more than 5 megawatts, and in 2030 for 1-5 megawatt plants. If combustion plants are put into operation before 20 December 2018, these requirements will apply to them as from that date.
The limit values for sulphur dioxide, nitrogen oxides and particulate matter will be stricter. Limit values will be introduced also for stationary engines and gas turbines. However, no limit value for carbon monoxide has been set. Operators will only have to carry out measurements of the concentration of this pollutant, estimate its annual emissions and submit reports on that. Countrywide summary data of such reports will be provided to the European Commission.

According to Eugenijus Leonavičius, if the new requirements for medium combustion plants are implemented in a timely and appropriate manner, especially as conditions are currently available for using the EU 2014-2020 financial support for renovation of boilers, it is likely that improved air quality, social environment and human health indicators will be achieved shortly.
