The MCPD stands for Medium Combustion Plant Directive and is a European Union (EU) directive aimed at controlling emissions from medium-sized combustion plants. The directive was introduced in December 2015 and came into effect on December 17, 2018. 

The MCPD applies to combustion plants with a rated thermal input between 1 MW and 50 MW, and covers a range of fuels, including biomass, coal, oil, and gas. The directive sets emission limit values for nitrogen oxides, sulfur dioxide, and particulate matter, and requires combustion plants to be operated in accordance with Best Available Techniques (BAT) to minimize emissions. 

The MCPD is designed to reduce emissions from medium-sized combustion plants, which are a significant source of air pollution in the EU. The directive aims to improve air quality and public health by reducing harmful emissions from these plants. It also aims to create a level playing field for businesses by setting common emission standards across the EU. 

Member states of the EU are required to transpose the MCPD into national law and enforce it through their regulatory bodies. Compliance with the MCPD is mandatory for medium combustion plants in the EU, and non-compliance can result in fines and other penalties. 

The emission limit values (ELVs) set out in the Medium Combustion Plant Directive (MCPD) for the UK are aimed at controlling emissions of nitrogen oxides (NOx), sulphur dioxide (SO2), and particulate matter (PM) from medium-sized combustion plants. 

The ELVs for NOx are set on a sliding scale based on the rated thermal input of the combustion plant, ranging from 1000 mg/Nm³ for plants with a thermal input of 1 MW or less, up to 175 mg/Nm³ for plants with a thermal input of 50 MW or more. For SO2, the ELVs range from 200 mg/Nm³ to 400 mg/Nm³, depending on the fuel type and the rated thermal input of the plant. The ELVs for PM are set at 30 mg/Nm³ for plants with a thermal input of 5 MW or more. 

The MCPD also requires that combustion plants be operated in accordance with Best Available Techniques (BAT) to minimize emissions. The BAT-associated emission levels (BAT-AELs) are set out in the directive and provide guidance on the maximum emissions that can be expected from a well-run combustion plant. The MCPD requires that all combustion plants comply with the BAT-AELs by 2027, although some plants may need to comply earlier if they exceed certain thresholds. 

It is important for businesses operating medium combustion plants to understand the emission limit values and BAT requirements set out in the MCPD to ensure compliance with the directive and avoid penalties for non-compliance.
