An amendment to the Environmental Permitting (England and Wales) (Amendment) Regulations was published at the beginning of the year to implement the Medium Combustion Plant Directive (MCPD). From 20th December 2018 new combustion plant in the range 1MW ? 50MW will require an Environmental Permit with upper limits on emissions of sulphur dioxide, nitrogen oxides and dust. This will include all boilers, combustion plant used electricity generation and Combined Heat and Power (CHP) units. Measures for existing plant will be implemented on a phased basis depending on the capacity of the plant, with implementation dates in 2024 and 2029. Additional permit requirements are proposed for ?Specified Generators? used for electricity generation, and are not connected to the electricity transmission and distribution network. Draft guidance on the implementation of the MCPD is due to be published by the EA in May.
