All local authorities are required to assess air quality in their areas. An Air Quality Management Area must be declared if pollutant concentrations are identified as exceeding, or likely to exceed, air quality objectives set out in The Air Quality Standards (England) Regulations 2007 and prescribed for Local Air Quality Management. These objectives must be met in any outdoor location where members of the public (receptors) are likely to be present.
The procedures that must be followed when investigating a likely breach of an air quality objective and when declaring an Air Quality Management Area are detailed in Technical Guidance LAQM.TG(22).
Derbyshire Dales District Council has declared 2 Air Quality Management Areas(AQMA).
An AQMA in relation to pollutant emissions from Stoneleigh Cottage Poultry Farm, Derby Road, Cubley was declared in February 2010. This was for a breach of the 24-h mean air quality objective for fine particulates (PM10). This objective for PM10 has a limit of
- 50 µg/m3, not to be exceeded more than 35 times a year.
This has now been revoked.
An air quality management area (AQMA) was declared for Nitrogen Dioxide on Detailed Assessment Buxton Road and St John's Street, Ashbourne on 5 May 2021. This was declared because it was likely the Nation Air Quality Objectives were being or likely to be exceeded.
The National Air Quality Objective for Nitrogen Dioxide is:
- annual average of 40ug/m3
- or a 1 hour mean of 200ug/m3, not to be exceeded more than 18 times a year.
