Local air quality management
The Councils' Public Health & Regulation Team has a key role in managing local air quality. The Team review and assess air quality against specific health based national objectives for seven key pollutants and are required to produce annual reports of air quality within Adur & Worthing.
Under the Environment Act 1995 every local authority must review present and likely future air quality within its area on an annual basis. Where air quality objectives (as set out in the Air Quality (England) Regulations 2000) are not being achieved, or are unlikely to be achieved within the relevant period, local authorities must designate Air Quality Management Areas (AQMAs). This applies only to those locations where members of the public might reasonably be exposed. An AQMA is a geographical area that is drawn up around a pollution hot spot. Once an area has been designated the local authority must carry out a further assessment and develop an Action Plan, describing what actions relevant agencies will be taking to try and comply with the relevant objective.

Council monitoring shows that levels at Lyons Farm and Grove Lodge continue to be elevated above the national annual mean objective for Nitrogen Dioxide (NO2) of 40µg/m3. A Further Assessment of air quality in and around the Grove Lodge AQMA, prepared by Sussex-air for the Council, confirmed that levels of NO2 are predicted to continue to exceed the annual average objective for NO2 in the area around Lyons Farm, Grove Lodge (A27) and Offington Corner (A27/A24 junction).
Consequently, following a period of consultation the existing Grove Lodge Air Quality Management Area (AQMA) was extended. The 'Worthing Borough Council Air Quality Management Area No.2' came into force on 15th December 2014. The designated area incorporates:
- the eastern end of Crockhurst Hill from the eastern boundary of Durrington Cemetery towards Offington Corner Roundabout
- Offington Corner Roundabout
- Warren Road
- 1-3 Warren Farm Place
- 1 Links Road
- Hill Barn Lane
- 17 Mansfield Court Sanditon Way
- Grove Lodge Roundabout
- Grove Lodge
- 1-2 Grove Lodge Cottages
- 22-27 Lamorna Grove
- Upper Brighton Road leading onto the Sompting Bypass, up to and including the Downlands Retail Centre
- and Lyons Way
Following on from the completion of a Review and Assessment of Air Quality at the end of December 2000, we carried out an Updating and Screening Assessment (USA) of Air Quality in May 2003. The conclusions of this USA meant that a further Detailed Assessment (DA) of Air Quality was carried out on certain parts of the District.
This showed that the Air Quality Objective for nitrogen dioxide was likely to be breached in two areas of Adur - High Street, Shoreham-by-Sea and Old Shoreham Road, Southwick, in the vicinity of Kingston Lane. This resulted in two Air Quality Management Areas being declared in December 2005.

Old Shoreham Road, Southwick AQMA:
Where an AQMA has been declared, the local authority must produce an Action Plan which sets out the options for working towards improving the air quality. We are updating our draft Plan which will set out how we intend to work towards reducing levels of nitrogen dioxide in the AQMA. As the elevated levels are primarily caused by traffic, we will be working with the Highways Agency (responsible for the A27) and West Sussex County Council (the other highway authority) to look at ways of reducing levels of nitrogen dioxide.
The Councils have published Air Quality Action Plans for both the Worthing and Shoreham Air Quality Management Areas (AQMA). The Action Plans set out measures devised to try and deliver improvements to air quality by reducing pollution emitted from vehicles and the amount of traffic passing through the AQMAs. The Plans includes actions specifically targeted at the AQMAs and measures that will affect the Districts as a whole. Some actions will involve Highways England, as the A27 is a trunk road under their jurisdiction, and West Sussex County Council who are responsible for all other roads in Adur and Worthing. Other actions will target reducing emissions from various sources across the two Districts that contribute towards the background pollution levels within the AQMAs. It is hoped these will also help to reduce pollution across the Districts.

We are always interested in the views of members of the community on how we can reduce levels of pollution.
You can submit your views by contacting the Public Health & Regulation Team and clearly stating 'Air Quality' using our on-line contact form:
Exceedances of the hourly mean objective for monitoring at Grove Lodge suggests levels of Nitrogen Dioxide (NO2) exceed 60ug/m3. Guidance states that exceedance of the 1-hour mean objective for NO2 is indicated when measured levels regularly exceed 60ug/m3.
Defra have therefore suggested we redesignate the existing Worthing Air Quality Management Area (AQMA) to include exceedance of the 1-hour mean for NO2.
The Council has a statutory duty to review air quality within its area and compare the levels of specific pollutants with National Objectives (target levels) to be achieved. Where these levels have exceeded, or are predicted to exceed the objectives, the local authority is under a legal duty to declare an Air Quality Management Area (AQMA).
The air quality objectives are set out in the Air Quality (England) Regulations 2000, as amended by the Air Quality (England) (Amendment) Regulations 2002.
Air Quality Objectives included in Regulations for the purpose of LAQM in England
Pollutant: Nitrogen dioxide - Air Quality Objective:
- Measured as 1-hour mean:
Concentration 200 µg/m3 not to be exceeded more than 18 times a year
- Measured as Annual mean:
Concentration 40 µg/m3
Section 82 of the Environment Act 1995 states that every local authority shall review both the present and likely future air quality within its area. Section 83 requires local authorities to designate an AQMA where air quality objectives are not being achieved, or are not likely to be achieved within the relevant period, as set out in the Air Quality (England) Regulations 2000. This applies only to those locations where members of the public might reasonably be exposed.
What is an AQMA?
An AQMA is an area where the local authority is aware that there is a problem with air quality and consequently must actively work towards improving air quality within
that area. The boundary of an AQMA is generally based upon computer models and monitoring results, but is also drawn according to existing geographical features to provide easily understandable maps. The boundary of the AQMA is shown below. There are no changes planned to this boundary.
The Worthing Borough Council Grove Lodge AQMA was first declared in 2010, for exceedances of the NO2 annual mean. It was subsequently extended in 2014. The AQMA is shown hatched in red on the plan below.
What is the issue?
Government guidance states that any monitoring site exceeding 60µg/m3 as an annual mean for Nitrogen Dioxide risks exceeding the 1-hour mean objective of 200µg/m3. A diffusion tube monitoring site adjacent to Grove Lodge Cottages on the A27 has exceeded 60µg/m3 for many years (see the plan below for the monitoring site location). Feedback from Defra following submission of our Annual Status Reports (ASR's) advises Worthing Borough Council to amend the existing AQMA to incorporate exceedance of the 1-hour mean objective for NO2.
Location of Monitoring site exceeding the 1-hour mean
What is the proposal?
The proposal is to re-declare the current AQMA to include an exceedance of the hourly mean for NO2. No other changes are proposed. The boundary of the current AQMA will remain the same.
If the Council were to do nothing it risks breaching its legal duties under the Environment Act 1995.
- The Council are legally obliged to hold a period of consultation regarding the proposed change before it can be officially declared.
- The consultation lasted for 21 days.
- The closing date for comments was 8th April 2019.
- The consultation has now closed and we are considering any responses.
Comments should be sent to:
or by post to:
- Environmental Protection Team,
Public Health & Regulation,
Adur & Worthing Councils,
44 Richmond Road,
West Sussex, BN11 1HS
What happens after the consultation?
The results of the consultation will be reported to the Executive Member for the Environment. A draft Order declaring the AQMA will also be placed before the Executive Member.
