Medium Combustion Plant Directive (MCPD) implications for chemical sites
The Medium Combustion Plant Directive (MCPD) forms part of the EU’s Clean Air Policy and fills a regulatory gap between small and large combustion plant, targeting emissions from combustion plants of between 1 and 50MWth input.
The Environmental Permitting Regulations (England and Wales) were amended in 2018 to implement the requirements of the ‘Medium Combustion Plant’ (MCP) Directive and additional controls on ‘Specified Generators’. In short, the amendments require operators to obtain and comply with the conditions of an environmental permit if they operate a MCP or Specified Generator, with a small number of exemptions.
‘Medium Combustion Plant’ (MCPs) are defined as combustion plant with a thermal input rating between 1MWth and 50MWth.
‘Specified Generators’ (SGs) are those MCPs that generate electricity for >50hrs per annum (incl. testing) or export electricity to the grid.
The dates by which MCPs and SGs are required to obtain an environmental permit differ depending on whether they are MCPs or SGs, age, thermal input, emissions, and capacity market agreements.
Key dates for MCPs
Key dates for MCPs are as follows:
Key dates for SGs
Key date for SGs are as follows:
Tranche A generators are those which came into operation before 1st December 2016, or benefit from capacity agreements from the 2014 and 2015 capacity market auctions or generators <1MWth with capacity agreements from the 2016 capacity market auction.
There are several exemptions relevant to the chemical industries including for:
