Horsham District’s Air Quality Management Areas (AQMAs)

An Air Quality Management Area (AQMA) is a geographical area surrounding a pollution hot spot. Over 230 have been declared across the UK, varying in size from single properties to entire boroughs. Every AQMA has its own Action Plan.

There are two AQMAs in Horsham District:

  • Storrington Air Quality Management Area, declared in 2010
  • Cowfold Air Quality Management Area, declared in 2011

All AQMAs are required to have an Air Quality Action Plan that reviews all possible pollution reduction measures and assesses them in terms of pollution reduction, acceptability, cost effectiveness and feasibility. The AQAPs have been developed in partnership with West Sussex County Highways Department. They are  reviewed every 12 months as part of the annual progress reporting schedule required by the Department for Environment, Food and Rural Affairs (DEFRA).

An Air Quality Management Area has been in effect in Storrington since December 2010 in areas of the village that are likely to exceed the annual air quality objective for nitrogen dioxide.

Storrington's Air Quality Action Plan

The measures recently taken forward for implementation to reduce traffic congestion and to aid air quality improvement in Storrington are:

  • Weight restriction for lorries on B2139 Manleys Hill between the A283 Manleys Hill/High St mini-roundabout and Mill Lane car park entrance within the Storrington AQMA; and
  • Restrictions for waiting, loading and unloading at any time on sections of North Street, The Square and West Street in Storrington.

Does Storrington have a Low Emission Zone?

No. A low emission zone trial was carried out in 2014/15 and it was concluded that such a zone would not be possible. For more information, please read the Storrington Low Emission Zone Project Report.
