The Council carries out monitoring and assessment of air quality within the Borough
We are required by law to assess the quality of air to determine if it is likely to meet the standards set out in the Government’s Air Quality Objectives. These objectives relate to seven pollutants:
- carbon monoxide
- 1,3 - butadiene
- nitrogen dioxide
- sulphur dioxide
- particulate matter
Air quality has been monitored for a number of years and the Council is satisfied that the air quality objectives are being met for all the pollutants except for nitrogen dioxide (NO2). Nitrogen dioxide is a pollutant largely linked to road traffic vehicle emissions; further information on the significance of nitrogen dioxide as a pollutant is contained in this document: Nitrogen Dioxide Summary
The air quality objective for nitrogen dioxide is a yearly average of 40ug/m3 (micrograms per cubic metre). The Council submits an annual report to Defra to inform Government of the outcome of our monitoring. Further information on current levels of pollutants including data and reports from Brentwood is collated and presented on the Essex Air website which also provides information from Councils across Essex.
Air Quality Management Areas
If an area is not likely to meet the Government’s Air Quality Objective then the Council is obliged to designate an Air Quality Management Area (AQMA). In Brentwood there were predicted exceedances of the Air Quality Objectives in a number of areas, which resulted in the declaration of seven areas as AQMAs in the Borough in 2004/5. All of these areas are near to busy roads, principally the M25 and A12 and in Brentwood town centre:
- Nags Head Lane at its junction with the M25
- Brook Street at its junction with the M25 and A12 (Brook Street Roundabout)
- Greenshaw/Porters Close near to the A12 Brentwood Bypass
- Warescot Road/Hartswood Avenue/Ongar Road at their junction with the A12
- B1002 Roman Road, Mountnessing close to A12
- Fryerning Lane, Pemberton Avenue and Trimble Close close to the A12
- Junction of A128/A1023 - Wilson’s Corner
A copy of the maps of the Air Quality Management Areas that were declared can be viewed here: Brentwood AQMA maps
Declaring an Air Quality Management Area does not mean that the air quality will improve, but the Council has to produce an action plan to help to reduce the effects of pollution by working with the Highways Agency (the Government body responsible for the major roads such as the M25 and the A12) and Essex County Council (responsible for other main roads such as the A128 and A1023) to examine ways of improving the quality of air in Brentwood.
Four of the original AQMAs declared in Brentwood have now been revoked, following several years of compliance with the Air Quality Objectives and a trend towards improved air quality - these AQMAs were associated with the A12. The remaining three AQMAs are listed in bold type above.
