What is the BREF?
The ‘BREF’ is the European guidance document for the Industrial Emission Directive (formerly IPPC) for the pig and poultry sectors.
It outlines Best Available Techniques (BAT), or best practice, covering a range of activities on farm which must be transferred into guidance (e.g. how to comply) in England and Wales. It is applicable to all permitted pig and poultry units which house more than:
- 40,000 poultry places;
- 2000 production pigs (over 30kg); or
- 750 sows;
It is enforced by the Environment Agency in England and Natural Resources Wales in Wales.
The BREF was last updated in 2003 and is now being revised.
