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 submits its Air Quality Reports on an annual basis and publishes them on this web page once the conclusions have been accepted by the Welsh Assembly Government.

Progress Report 2015

This report is a continuation of the Updating and Screening Assessment (2014) and evaluates the Air Quality in the County Borough for 2015. It mainly looks at the monitoring conducted over the year as well as seeking to identify if there are any new sources that require evaluation.

Updating and Screening Assessment (USA) 2014

This report evaluates the Air Quality in the County Borough during 2014. It considers whether any new sources identified since the last USA could have an adverse impact on Air Quality. It also discusses the results of Wrexham County Borough Councils air monitoring carried out in 2014.

Progress Report 2013

This report is a continuation of the Progress Report (2012) in which the air quality in Wrexham County Borough Council for 2013 is evaluated. It considers the results of the monitoring undertaken by the Council as well as reviewing the Borough for any potential new sources or developments which may have affected air quality.

Progress Report 2012

This report is a continuation of the above Updating and Screening Assessment (2011) and evaluates the Air Quality in the County Borough for 2012. It mainly looks at the monitoring conducted over the year as well as seeking to identify if there are any new sources that could lead to the Air Quality Objectives being exceeded in the County Borough.

Updating and Screening Assessment (USA) 2011

This report evaluates the Air Quality in the County Borough during 2011. It re-evaluates all the sources discussed in previous reports to identify any changes that could have an adverse impact on the Air Quality in the County Borough. It also considers the results of the Wrexham Councils Air Quality monitoring carried out in 2011.

Progress Report 2010

This report is a continuation of the above Progress Report (2009) and evaluates Wrexham County Borough Council’s air quality during 2010. It is mainly concerned with the monitoring undertaken by the Council over the year as well as seeking to identify any new sources or developments that could lead to the Air Quality Objectives being exceeded in Wrexham.

Progress Report 2009

This report is a continuation of the above Updating nad Screening Assessment (2008) and evaluates the Air Quality in the County Borough for 2009. It mainly looks at the monitoring conducted over the year as well as identifying if there are any new sources that could lead to the Air Quality Objectives being exceeded in an area.

Progress Report 2008

This report is a continuation of the above Progress Report (2007) and evaluates the Air Quality in the County Borough for 2008. It mainly looks at the monitoring conducted over the year as well as identifying if there are any new sources that could lead to the Air Quality Objectives being exceeded in an area.

Progress Report 2007

This report is a continuation of the above Progress Report (2006) and evaluates the Air Quality in the County Borough for 2007. It mainly looks at the monitoring conducted over the year as well as identifying if there are any new sources that could lead to the Air Quality Objectives being exceeded in an area.

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.

Updating and Screening Assessment 2005 (USA)

This is a repeat of the USA process 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 2003/2004

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 (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.

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.

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 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 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.
