The Clean Air Act 1993, introduced a wide range of regulations such as those which control smoke emissions and the height of chimneys, and those relating to the content and composition of motor fuels. The control of chimney heights enables local authorities to take into account a number of relevant factors in determining the height of a chimney. 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 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.
An application for chimney height approval must contain adequate information to enable the necessary calculations on air quality impact to be carried out. For more information/advice contact the council.
