Decision

Revocation of the Air Quality Management Area (AQMA) for High East Street, Dorchester.

Reasons for the decision

The AQMA was declared in 2009 when the NO2 annual mean was found to exceed 40µg/m3. An Air Quality Action Plan (AQAP) was drawn up to improve the air quality in this area. 

Since 2009 the NO2 levels have generally declined in this management area. 

Since 2019 the NO2 levels have been consistently below the objective, and in 2023 were found to be 28.2 µg/m3. DEFRA have agreed with Dorset Council that the air quality has significantly improved, and a revocation is appropriate.  

A consultation with key stakeholders offered found no objections to the revocation.  

Alternative options considered
