Welcome to Epping Forest!

Epping Forest District is an attractive, predominantly commuter area in the south west of Essex on the northeastern edge of London. The district has a population of around 121,000, of which nearly three quarters live in the suburban towns of Loughton, Buckhurst Hill, Chigwell, Epping and Waltham Abbey. The remaining quarter live in the surrounding rural areas including large villages such as Roydon, Nazeing, North Weald and Theydon Bois.

The main source of air pollution in the borough is road traffic. There are two large motorways in the district; the M25 and the M11 however the air quality issues are located in the urban areas, principally caused by stop-start traffic congestion.

We currently monitor nitrogen dioxide using 64 passive diffusion tubes at 28 monitoring locations around the district. Unfortunately we no longer have any continuous monitoring equipment.

Our reviews and assessments of air quality have kept us busy over the years, and the full list of reports can be found and downloaded below using the `reports` tab on this page. In summary, we have declared a couple of AQMA`s for Nitrogen Dioxide in Epping and revoked one that was no longer required. We may need to declare a few more AQMA`s in Epping and Loughton for Nitrogen Dioxide from stop-start traffic depending on whether or not the general improvements in cleaner vehicle technology deliver the desired results.

Recently we have been analysing the impact of emissions on air quality from the locomotives on the Epping Ongar Railway. Our nitrogen dioxide diffusion tubes have so far demonstrated that there is no appreciable impact on air quality over the monthly exposure period. We have also assessed hourly exposure to train emissions using new rapid air monitors (RAM), and note that the hourly nitrogen dioxide exposure objective has not been exceeded. Monitoring in relation to the Epping Ongar Railway will cease at the end of 2013 and an update on results will follow in the 2014 Progress Report.

And finally.......

The air quality review and assessment process is currently being reviewed at a national level, and may radically change how we review and assess air pollution. Please see the following web pages for more information:
