Medium Combustion Plant Directive and Specified Generator Regulations

Closed 19 Aug 2019

Opened 6 Sep 2018


The Environmental Permitting (England and Wales) (Amendment) Regulations 2018 SI 110 were published in January 2018 to transpose the requirements of the Medium Combustion Plant Directive (MCPD) EU/2015/2193 of 25 November 2015 and to control emissions from the operation of Specified Generators

Medium Combustion Plants and Specified Generators are a major source of air pollutants that may cause harm to human health and the environment.  The Medium Combustion Plant Directive (MCPD) sets out rules to control emissions of sulphur dioxide (SO2), nitrogen oxides (NOx) and dust into the air. The Specified Generator regulations also control emission to air, primarily NOx, from generators that would not be captured by the MCPD. Together they seek to protect the environment by securing reductions of these pollutants.

Within the regulations the requirements for Medium Combustion Plants (MCPs) are set out in Schedule 25A and for Specified Generators (SGs) in Schedule 25B. The schedules include significant dates for submitting a permit application.

The Environment Agency administers and regulates the scheme for England. The other UK regulators include: Scottish Environment Protection Agency (SEPA), Northern Ireland Environment Agency (NIEA) and Natural Resources Wales (NRW)
