Air quality assessment
When is an Air Quality Assessment required?
Where the development is proposed inside, or adjacent to an air quality management area (AQMA), or where the development could in itself result in the designation of an AQMA or where the grant of planning permission would conflict with, or render unworkable, elements of a local authority’s air quality action plan, applications should be supported by such information as is necessary to allow a full consideration of the impact of the proposal on the air quality of the area. Where AQMAs cover regeneration areas, developers should provide an air quality assessment as part of their planning application.
Further advice is available in Planning Policy Statement 23: Planning and Pollution Control (November 2004).
