See here for the Environment Agency’s information on agricultural waste exemptions.
New regulations introduced on 6 April 2010 changed the system of waste exemptions. Farm-based exemptions registered before 6 April 2010 will expire on 30 September 2013. New exemptions should be registered by 30 September 2013.
The regulations which implemented this change are the Environmental Permitting (England and Wales) Regulations 2010.
The old waste exemptions are replaced by a completely new list of exempt waste activities. The new exemptions are grouped into five categories:
• Non- registerable exemptions – also known as Non – Waste Framework Directive exemptions. You don’t have to register these.
• Use of waste -U
• Treatment of waste – T
• Disposal of waste – D
• Storage of waste – S
Some of the new exemptions are almost identical to exemptions in the old system, some are similar but have different limits and conditions, and some are completely new.
