The Vale of Glamorgan Council is to carry out a public consultation on whether or not to revoke the Air Quality Management Area in Windsor Road Cogan.
The Air Quality management Area was set up some five years ago because of the air pollution caused by passing traffic – and diesel trains – in the area around the “Cogan Dip”
The council says the latest report confirms that all air quality within the Vale of Glamorgan – including the AQMA in Windsor Road – “meets relevant air quality objectives”.
The council says that now there are “no monitoring sites with nitrogen dioxide (NO2) concentrations above 60µg/m3 in 2017 anywhere in the Vale of Glamorgan “.
A monitoring station in Windsor Road shows that “the annual average particulate matter PM10 concentration” [ very fine pollution produced by diesel engines] ” .. is compliant with the AQS objective” [i.e maximum, permitted level] “of 40µg/m3.”
As far as Ozone (O3) is concerned , the report states “There are no exceedences of the 8-hour mean objective of 100µg/m3 on more than 10 days per year as set by the Expert Panel on Air Quality Standards (EPAQs). “. [Ozone is normally present at very high altitudes in the troposphere but when it forms at ground level – when pollution from cars reacts with Ultra Violet light – it can irritate human lungs]
However the Vale Council report says “A detailed assessment is yet to be finalised to support this decision to revoke the Windsor Road AQMA and demonstrate compliance with the air quality objectives for future years for the defined AQMA.”
Next week the Vale Council’s ruling cabinet will be asked to agree that a public consultation be undertaken “on the removal of the revocation of the AQMA on Windsor Road”. [PDN Note: This sentence is a confusing and probably-erroneous double-negative].
The final decision to revoke – or not revoke – the Windsor Road AQMA will be made in due course by the Welsh Labour Government after the public consultation
