Local Authorities are required to assess and report every year to the government on the air quality in their local area. The reports must assess whether the statutory health-based objectives are being met. Where the objectives are not being met, a Local Authority has to produce an Air Quality Action Plan to improve local air quality.
These reports provide an overview of air quality in Arun District Council.

Arun District Council: Review and Assessment Summary
The review and assessment of air quality in this authority has been undertaken following the Local Air Quality Management process. The link to the local authority air quality reports is below: Arun D.C. Air Quality Reports
There are no air quality management areas in Arun District
Arun District Council has completed it’s stage I, II and III air quality review and assessment. Arun District Council undertook assessments for roads and industrial sources in the area, undertaking monitoring and modelling of sources to ascertain their air quality impacts.
Advanced modelling was undertaken using the BREEZE ROADS model which incorporates emissions, traffic and meteorological data and provides estimates for both moving and idling vehicles. Predicted NO2 concentrations for 2005 were found to be less than the required air quality objective, so it was not necessary to declare an Air Quality Management Area (AQMA).
The contribution of SO2 and PM10 from the Lafarge Redland stack was estimated using the GSS Environment Agency model, incorporating geographical and engineering data. When this value was added to the predicted background concentration, the total SO2 concentration for 2004/2005 was found to be below the air quality objectives set for SO2 Therefore no further assessment was needed. However, for PM10 the predicted total 2004 concentration was found to be within 5 mg/m3 of the annual mean air quality objective, so advanced modelling was undertaken to confirm whether the objective would be met by 2004. The advanced AERMOD model results were of similar concentration to those from the GSS model and therefore it was decided not to proceed further.
