Clean Air Act Approval
To protect against high concentrations of air pollutants at ground level, which could create health effects, the Clean Air Act 1993 allows Local Authorities to control the height of chimneys serving industrial processes.
Under section 14 of the Act, unless the height of the chimney has been approved by the local authority and any conditions attached to approval adhered to, it is an offence to cause or knowingly permit a furnace to be used to:
- burn pulverised fuel
- burn at a rate of 45.4 kg or more an hour any other solid matter or
- burn at a rate equivalent to 366.4 kW or more any liquid or gaseous matter
The theory behind this is to ensure that emissions from chimneys exit at high levels to aid dispersion and dilution and limit the process of gravity from bringing high concentrations of grit, dust, soot and gases down to ground level.
Applications for chimney height approval always contain technical data and calculations to support the overall height applied for and Local Authorities will ensure that information is correct before granting an approval. The Local Authority may also attach conditions to approvals.
In addition provisions are also contained within legislation dealing with prescribed processes under the Environmental Protection Act 1990 and the Pollution Prevention and Control Regulations 2000; details of these processes in Tendring District Council can be found under Authorised Processes.
