The below examples of Detailed Assessments and Detailed Modelling Studies show a range of approaches taken by local authorities in order to provide additional information to support the decision to declare, amend or revoke and Air Quality Management Area (AQMA). Whilst Detailed Assessments are no longer a formal requirement for local authorities in England, Scotland or Wales, the guiding principles are still of relevance when developing detailed modelling studies to support air quality activities within a local authority area.
