A new version of the Guidance on the assessment of odour for planning has been published. This version is edited by the Institute of Air Quality Management. This version from July 2018 reviews and modify some text, tables and diagrams from the previous version.
The planning system has the task of guiding development to the most appropriate locations: ideally, significant sources of odour should be separated from odour-sensitive users of the surrounding land (sensitive receptors); failing this, it may be possible to employ control and mitigation measures to make a proposed development acceptable from a land-use perspective. New proposals for such developments may require an odour impact assessment to be submitted, either as a stand-alone assessment or as part of an Environmental Statement, to accompany the planning application.
