Part B Processes / Installations
Combustion plant with a thermal input capacity of 20-50MW will generally be regulated by Local Authorities in England and Wales (under LAPPC) and by SEPA in Scotland.
The relevant Guidance Notes issued by Defra, are:
- PG1/3 Boilers and Furnaces, 20-50MW Net Rated Thermal Input.
- PG1/4 Gas Turbines, 20-50MW Net Rated Thermal Input.
- PG1/5 Compression-ignition Engines, 20-50MW Net Rated Thermal Input.
These Guidance Notes are issued as a guide to local enforcing authorities on the techniques appropriate for the control of air pollution for the process.
In the case of Part B plants, it is the rated input of the individual gas turbine, engine or boiler that is compared with the 20-50MW threshold and regulated accordingly. Aggregation of the rating of multiple units of plant is not carried out.
