EQ4 Air Quality

The effect of development upon air quality is a material consideration. All applications should take account of the Council’s Air Quality Planning Guidance Document, which details when an air quality assessment is required.

All development should take account of the Council’s latest Air Quality Action Plan, local Air Quality Strategies, Local Transport Plans, as well as national air quality guidance.

All developments should include measures to minimise air quality impact at the design stage and should incorporate best practice in the design, construction and operation of all developments.

Where development (on its own or cumulatively) will have a negative impact on local air quality during either construction or operation, mitigation measures will be sought that will remove overriding impacts, such as an air quality neutral or negative development. Evidence of mitigation measures will be required upfront.

Where on-site mitigation is not sufficient, appropriate off-site mitigation measures may be required. Where adequate mitigation cannot be provided, development will not normally be permitted.

Developments must not:

  • lead to a breach or worsening of a breach of UK or EU limit values;
  • lead to a breach or worsening of a breach of an Air Quality objective or cause the declaration of an Air Quality Management Area or;
  • prejudice the implementation of any Air Quality Action Plan or local air quality strategy.
