Hafod-Yr-Ynys Air Quality Feasibility Study (WelTAG Stage 3) Consultation

The European Union Ambient Air Quality Directive (2008/50/EC) sets legally binding limits for concentrations of certain air pollutants in outdoor air termed ‘limit values’. The A472, Hafod-yr-Ynys Road exceeds the limit value for nitrogen dioxide (NO2) and Caerphilly County Borough Council is investigating measures to bring forward reductions in NO2 to ensure compliance with the Ambient Air Quality Directive in the shortest possible time.

A feasibility study has predicted that a ‘Do Minimum’ scenario, which involves public awareness raising and educational campaigns would achieve compliance by 2025.  The study also assessed a number of options and concluded that demolition of the houses at 1-20 Woodside Terrace to include 1&2 Woodside Shops and Yr Adfa will achieve compliance with the air quality limit values in the shortest possible time; by 2023.

Caerphilly Council’s Cabinet have considered the findings from the study. Following deliberations regarding the potential impact on the mental health and well-being of the residents, together with the potential to create financial hardship; the Cabinet agreed to consult on the ‘Do Minimum’ option as the preferred option for securing compliance with the Air Quality Directive. In addition, the Council is lobbying Welsh Government for additional financial support, in order to prevent those affected residents being forced into financial hardship in the event that the demolition option is subsequently required.
