Progress Report - Air Quality Issues within West Wiltshire (April 2004)

This progress report provides a review and update on air quality issues within West Wiltshire and includes information on developments that may affect air quality and the results of monitoring for 2003.

This report is not a further Updating and Screening Assessment, it is a report to assist the local authority. It can help in many ways such as helping Local Authorities to respond to requests for up to date information on air quality, provide a means of communicating air quality information to members of the public and maximise the value of investment in monitoring equipment.

Progress Reports are designed to ensure continuity in the Local Air Quality Management Process (LAQM). A local authority is only required to produce a Progress Report in years when the authority is not carrying out an Updating and Screening Assessment or a Detailed Assessment. West Wiltshire District Council did not have to proceed to a Detailed Assessment following the Updating and Screening Assessment completed in July 2003.

The monitoring results obtained in 2003 across the district show that there are no other areas of concern and that the two Air Quality Management Areas (AQMAs) at Bradford On Avon and Westbury declared in November 2001 shall remain.
