Air quality assessment
Used to assess the impacts of proposed development on the air quality either in isolation or cumulatively with other developments.
Any development meeting the following criteria will normally be required to complete a full air quality assessment in order to predict the impact of the development on air quality.
- if the development provides 50 or more new parking spaces or more than 25 in an AQMA (Air Quality Management Area) (Kendal only)
- residential development of more than 80 units or more than 1.0ha site area
- industrial or commercial development with a floor space over 2,500m2
- industrial or commercial development with the potential for emissions to air, Use Class B1(1500m2), Use Class B2 (2,500m2) and Use Class B8 (3,000m2)
- coach or lorry park or distribution warehouse
- sensitive development (residential, school, healthcare etc.) within an AQMA (Kendal only)
- development that is a prescribed process under the Environmental Permitting Regulations
- sensitive development close to an existing prescribed process
- development that will significantly alter flows or speeds on busy roads (of more than 10,000 vehicles per day) or any road in an AQMA (Kendal only)
- development that will lead to a change in traffic volume of 2% of the annual average daily traffic (AADT) or 1% AADT within an AQMA (Kendal only)
- development that will lead to a change in average vehicle speed of 5km per hour or a significant increase in congestion
- development that would significantly alter the road or rail network (e.g. construction of new road)
- development that will lead to a change in vehicle split to a greater percentage of heavy duty vehicles (including buses)
- development that is part of a major phased redevelopment
- development that may create a street canyon (where the building height on both sides of the road is greater than its width)
Examples of proposed development likely to need an air quality statement.
- increase in congestion or HGV movements
- significant amounts of car parking
- significant dust emissions
- introduction of sensitive development (dwellings, schools, hospitals) other into an area of poor air quality
For information on whether an air quality statement should be submitted with your planning application please seek pre-application planning advice.
