Air Quality Reports

All local authorities have a duty to inspect air quality in their area in order to determine whether air quality standards and objectives are being achieved. Wrexham County Borough Council has completed the three-stage review and assessment process for the Air Quality Strategy.

Stage 1 Report

The aim of the Stage 1 Review is to establish if any 'significant' existing or proposed sources of the regulated pollutants are unlikely to meet the air quality standards. The Wrexham County Borough Council Air Quality Strategy Stage 1 Review highlighted that particulates (PM¹⁰) and oxides of nitrogen (NOx) needed further investigation to determine whether the standards and objectives would be met.

Stage 2 Report

If the information gathered during the Stage 1 Review suggests that standards are unlikely to be met, a more detailed assessment should be carried out under the Stage 2 Review. The Wrexham County Borough Council Air Quality Stage 2 Review highlighted that industrial sources were unlikely to cause breaches of NOx and particulate standards and road traffic emissions would not be in breach of the standards for PM¹⁰ or NOx. However additional data was required to determine if domestic coal burning was likely to breach SO² and PM¹⁰ standards.

Stage 3 Report

If Stage 1 and 2 Reviews indicate that air quality standards are unlikely to be met then the local authority will carry out a detailed and accurate third stage air quality review and assessment. If this establishes the likelihood of a specific pollution problem, an 'Air Quality Management Area' (AQMA) may be declared, and an action plan drafted in order to bring pollutant levels within Air Quality Standards by the year 2005.

Stage 4 Report

If an AQMA is declared a Stage 4 Review will set out an action plan detailing the various measures and target dates for meeting the required air quality standards. The action plan will be revised accordingly.

Updating and Screening Assessment (USA) 2003

The USA is intended to identify significant changes that may have occurred since the first round of Review and Assessment, which may lead to a risk of the Air Quality standards being exceeded. They often report on new monitoring data, new or increased emission sources, such as from new industrial companies or any changes that may have been made to the Air Quality Standards.

Progress Report 2004/2004

The progress report is a continuation of the Review and Assessment process, which much like the USA considers new monitoring data and new or increased emissions sources. It also identifies new planning applications that may impact on the air quality, such as from a large commercial development that may give rise to an increase in road traffic associated pollution.

Updating and Screening Assessment 2005 (USA)

This is a repeat of the USA process described above where any significant changes since the last USA or new developments, which may lead to a risk of the Air Quality Standards being exceeded, are considered. The report also re-examines potential pollutants that may not have been required under the Progress Report criteria, for example previously considered traffic sources.

Progress Report 2006

This report is a continuation of the above USA (2005) and evaluates the Air Quality in the County Borough for 2006. It mainly looks at the monitoring conducted over the year as well as identifying if there are any new sources that may exceed the Air Quality Objectives.
