Best available techniques for assessment and control of odour

Provides a body of information on the assessment and control of odorous emissions, operations and activities.



The Environment Agency has responsibilities for regulating odorous releases from a wide range of industrial activities under Pollution Prevention and Control (PPC). It also has odour-related responsibilities under the Waste Management Licensing regime, some aspects of which will transfer to PPC. The Operators of prescribed activities (except landfills which will be required to meet the requirements of the landfill directive) will have to conduct their activities such that “all the appropriate preventative measures are taken against pollution in particular through the application of best available techniques”. This includes odorous releases. The term “odour” covers a very broad range of compounds released from a potentially wide range of industrial activities. Odour can be a very subjective issue; a given exposure will evoke a different response between individuals. The requirement is to avoid harm which, in the case of odour, is considered in terms of “offence to the senses of human beings”.
