Draft PPS18: Renewable Energy
Annex 1 Energy from Waste (Thermal Processes) Planning Issues: Visual Effects
D25. In many cases, Energy from Waste developments are likely to be proposed in industrial areas, where they will be broadly in keeping with the existing buildings. Even so, the developments can be prominent features, and therefore the Department will expect a high standard of design and landscaping in order to minimise their visual impact.
D26. Chimney height will vary with the scale of plant and the technology used. Pyrolysis and gasification plant generally need significantly lower stack height than incineration. Chimney height will be determined by pollution control procedures under the Pollution Prevention and Control Regulations (Northern Ireland) 2003 or the Clean Air (Northern Ireland) Order 1981, to ensure adequate dispersal of emissions in the exhaust gas.
