Under the Clean Air Act 1993 local authorities may declare the whole or part of the borough of the authority to be a smoke control area.
It is an offence to emit smoke from a chimney of a building, from a furnace or from a fixed boiler if located in a designated smoke control area. It is also an offence to acquire an "unauthorised fuel" for use within smoke control area unless itis used in an "exempt" appliance ("exempted from the controls which generally apply in the smoke control area").
The current maximum level of fine is £1,000 for each offence.
The whole Borough is a smokeless zone area.
Although Broxbourne does not have a large industrial base which affects air quality, the council has a duty to regulate a number of industrial activities.
To protect against high concentrations of air pollutants at ground level, the Clean Air Act 1993 allows Local Authorities to control the height of chimneys serving industrial processes.
Broxbourne Borough Council must consider an application for approval for chimney height for a furnace. In addition, certain industrial processes are regulated by Pollution Prevention and Control Regulations 2000 within are provisions for calculating chimney heights.
