Emission limit values (mg/Nm³) for new medium combustion plants other than engines and gas turbines

Pollutant	Solid biomass	Other solid fuels	Gas oil	Liquid fuels other than gas oil	Natural gas	Gaseous fuels other than natural gas
The value does not apply in the case of plants firing exclusively woody solid biomass.
Until 1 January 2025, 1 700 mg/Nm³ in the case of plants which are part of SIS or MIS.
400 mg/Nm³ in the case of low calorific gases from coke ovens, and 200 mg/Nm³ in the case of low calorific gases from blast furnaces, in the iron and steel industry.
100 mg/Nm³ in the case of biogas.
500 mg/Nm³ in the case of plants with a total rated thermal input equal to or greater than 1 MW and less than or equal to 5 MW.
Until 1 January 2025, 450 mg/Nm³ when firing heavy fuel oil containing between 0,2 % and 0,3 % N and 360 mg/Nm³ when firing heavy fuel oil containing less than 0,2 % N in the case of plants which are part of SIS or MIS.
50 mg/Nm³ in the case of plants with a total rated thermal input equal to or greater than 1 MW and less than or equal to 5 MW; 30 mg/Nm³ in the case of plants with a total rated thermal input greater than 5 MW and less than or equal to 20 MW.
50 mg/Nm³ in the case of plants with a total rated thermal input equal to or greater than 1 MW and less than or equal to 5 MW.

Emission limit values (mg/Nm³) for new engines and gas turbines

Pollutant	Type of medium combustion plant	Gas oil	Liquid fuels other than gas oil	Natural gas	Gaseous fuels other than natural gas
Until 1 January 2025, 590 mg/Nm³ for diesel engines which are part of SIS or MIS.
40 mg/Nm³ in the case of biogas.
Engines running between 500 and 1 500 hours per year may be exempted from compliance with those emission limit values if they are applying primary measures to limit NO_x emissions and meet the emission limit values set out in footnote (4).
Until 1 January 2025 in SIS and MIS, 1 850 mg/Nm³ for dual fuel engines in liquid mode and 380 mg/Nm³ in gas mode; 1 300 mg/Nm³ for diesel engines with ≤ 1 200 rpm with a total rated thermal input less than or equal to 20 MW and 1 850 mg/Nm³ for diesel engines with a total rated thermal input greater than 20 MW; 750 mg/Nm³ for diesel engines with > 1 200 rpm.
225 mg/Nm³ for dual fuel engines in liquid mode.
225 mg/Nm³ for diesel engines with a total rated thermal input less than or equal to 20 MW with ≤ 1 200 rpm.
190 mg/Nm³ for dual fuel engines in gas mode.
These emission limit values are only applicable above 70 % load.
Until 1 January 2025, 550 mg/Nm³ for plants which are part of SIS or MIS.
Until 1 January 2025, 75 mg/Nm³ for diesel engines which are part of SIS or MIS.
