The Local Air Pollution Control (LAPC) and the Local Air Pollution Prevention and Control (LAPPC) systems were introduced as part of The Environmental Protection Act 1990. They are designed to impose conditions of control on emissions to the atmosphere from various industrial sectors covering approximately 17,000 individual processes.
These conditions can include controls over how a process is carried out as well as the setting of maximum permitted emission levels for certain types of pollutant; these are aimed at the protection of human health and the environment. Process Guidance Notes are published by the Secretary of State to help local authorities assess these 'prescribed' processes. Currently there are over 80 different types of industry covered by Process Guidance Notes, which offer a range of possible conditions to be considered and, where appropriate, applied to an individual process.
The final document which contains all of these conditions is called an 'Authorisation' or 'Permit' and the operator of a process is legally bound to adhere to these conditions.
