2012 Air Quality Updating and Screening Assessment for: Epping Forest District Council In fulfillment of Part IV of the Environment Act 1995 Local Air Quality Management Date (August, 2012) Epping Forest District Council Local Authority Fay Rushby Officer Department Public Health Environment & Street Scene Address Epping Forest District Council Civic Offices High Street Epping Essex CM16 4BZ Telephone 01992 564496 e-mail [email protected] Report WK/201214649 Reference number Date August 2012 LAQM USA 2012 1 Epping Forest District Council Executive Summary Epping Forest District is an attractive, predominantly commuter area on the north eastern 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. There are two large motorways in the district; the M25 and the M11 and the main source of air pollution in the district is road traffic. The air quality in the district is reasonably good with increased concentrations of vehicle emissions related polutants limited to congested high street areas and busy junctions. The District Council has completed all rounds of the review and assessment to date, which led to a number of detailed assessments for nitrogen dioxide. AQMA’s were declared for Epping High Street in 2010, and Bell Vue, Bell Common in 2011. The Epping High Street AQMA was declared on the basis of modelling information, but was revoked in 2011 on the completion of diffusion tube monitoring, which confirmed that nitrogen dioxide were below the air quality objective. All other reports judged that no AQMA was necesarry. Only one air quality management area remains, that being for Bell Vue, Bell common. An action plan is in the process of being agreed but has yet to be accepted by defra. Revisions to the source apportionment calculation are required. This updating and screening assessment builds on previous air quality work, and reports on 2011 monitoring data. The Updating and Screening Assessment has identified that there is no need to amend the boundaries of the current AQMA, and there is no need to declare any new AQMA. No local developments have the potential to impact on air quality other than the commencement of the Epping Ongar Heritage Railway. The Updating and Screening Assessment has identified the need for additional monitoring in relation to the Epping Ongar Railway. The impact (if any) of the operation of the railway is being reviewed and LAQM USA 2012 2 Epping Forest District Council will be reported in the 2013 Progress Report along with the need to progress to a Detailed assessment if necessary. The Updating and Screening Assessment has not identified the need to progress to a detailed assessment at this time. The proposed actions following this Updating and Screening Assessment are to: Ø Revise the source apportionment assessment for the action plan for the current AQMA. Ø Continue with the existing nitrogen dioxide monitoring survey. Ø Monitor at the Epping Ongar Railway for nitrogen dioxide and time spent idling at stations to see if a detailed assessment is required. Ø Submit a progress report in 2013.
