Under the Pollution, Prevention and Control Act 1999, Permitted Processes are those industrial activities that have a potential to cause pollution. The Pollution Prevention and Control regime requires that such processes must have a permit to operate.
There are currently three types of process classification:
Also regulated by local authorities - called LA-IPPC
What must Part A1 and A2 Installations control?
There are a wide range of activities that must be controlled from Part A installations, such as emissions to land, water and air. In addition, energy efficiency, waste reduction, raw materials consumption, noise, vibration and accident prevention must be effectively controlled.
What do Part B Installations have to control?
The permit for a Part B installation only covers emissions to air. Other emissions are likely to be controlled either by Sedgemoor DC under the Statutory Nuisance provisions of the Environmental Protection Act 1990 or by the Environment Agency.
There is a General Guidance Manual issued by Defra that contains detailed guidance on the the type, size, throughput of installations that need a permit. It covers the application process, compliance monitoring, and other issues such as variations and surrender. The Guidance is available here:
Local Authority Pollution Control: general guidance manual
There are also a series of what is called Process Guidance Notes. These cover the various types of activities that require a permit, for example there is one on quarries, petrol stations, paint sprayers, cement plants etc.
Application for a LA-IPPC Permit
You must have an environmental permit if you operate a regulated facility under the above legislation. Not all processes or installations are covered by the legislation as it is depends on the type and size of the operations being undertaken.
