The Medium Combustion Plant Directive (MCPD) Emission Level Values (ELV)
From 1st January 2025, emissions into the air of SO2, NOx and dust from an existing medium combustion plant with a rated thermal input >5MW shall not exceed the emission limit values set out in Tables 2 and 3 of Part 1 of Annex II.
From 1st January 2030, emissions into the air of SO2, NOx and dust from an existing medium combustion plant with a rated thermal input of ≤ 5 MW shall not exceed the emission limit values set out in Tables 1 and 3 of Part 1 of Annex II.
Part 1 – Annex II
Table 1
Emission limit values (mg/Nm3) for existing medium combustion plants with a rated thermal input equal to or greater than 1 MW and less than or equal to 5 MW, 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) |
| SO2 | 200 | 1,100 | – | 350 | – | 200 |
| NOx | 650 | 650 | 200 | 650 | 250 | 250 |
| Dust | 50 | 50 | – | 50 | – | – |
