Medium Combustion Plant Directive (MCPD) permitting, Trafford

Established in 1995 The Environment Agency is a non-departmental public body and is sponsored by the United Kingdom government's Department for Environment, Agriculture, and Rural Affairs.  The agency functions to uphold, protect, and enhance the environment throughout England. 

Ensafe were appointed to undertake a Medium Combustion Plant Directive (MCPD) permitting project via the Environment Agency to support an Environmental Permit Application. The MCPD regulates emissions from the combustion of fuels in plants with a rated thermal input equal to or greater than 1 Megawatt thermal (MWth) and less than 50 MWth.

The client’s Short Term Operating Reserve (STOR) site installation comprised of 8 natural gas-powered electricity generators with an overall thermal input of 47.72MWth. The installation will provide balance to the national grid during peak demand or where constraints on electricity capacity occur.

The Ensafe air quality team undertook a Dispersion Modelling Assessment which utilising ADMS-5 software which was required to support an Environmental permit application to the Environmental Agency (EA) for a proposed Short Term Operating Reserve (STOR) site. Given the nature of the installation, a Dispersion Modelling Assessment is required in support of a Complex Bespoke Environmental Permit application as required under the Medium Combustion Plant Directive (MCPD).

The team concluded that based on the predictions of the dispersion model, relevant Air Quality Environmental Standards were not exceeded at any sensitive locations within the modelling extents. Additionally, it was considered that overall air quality impacts associated with the operation of the facility would be insignificant in accordance with the Environment Agency significant criteria. The dispersion modelling and accompanying permit documentation was reviewed by the Environment Agency and subsequently granted to the client. Operations were therefore permitted subject to specific on-site conditions including monitoring regimes and annual operating restrictions.

We look forward to continuing to work on projects of this nature but also to the potential of working again with this client in the future.
