Epping Forest District CouncilLAQM Progress Report 20081. IntroductionThis Progress Report is a requirement of the Environment Act 1995, Part IV, whichplaces a duty on local authorities to periodically review and assess air quality withintheir location. The Progress Report follows on from the Updating and ScreeningAssessment (USA), which was carried out in 2006 as part of the third round of Reviewand Assessment. The USA report found a possibility that the NO 2 annual meanobjective could be exceeded and a Detailed Assessment was undertaken, which iscovered in greater detail below.The objective of the Progress Report is to provide continuity in the Local Air QualityManagement process by reporting any potential changes in air quality that may occurbetween the three yearly review and assessments of air quality.This report has been compiled with reference to the Progress Report Guidance(LAQM.PRG(03)) which was published by Defra in 2003. It presents information whichhas been collated since the production of the USA report, including: air qualitymonitoring data, information about emission sources and any proposed developmentswhich have the potential to affect air quality in the District.Outcomes of previous Review and Assessments for Epping ForestEpping Forest District Council carried out the First Round of review and assessment,including Stage 1, 2 and 3 reports, between 1998 and 2000. Modelling of pollutantscarried out for the first round of Review and Assessment indicated that the objectiveswere likely to be achieved at most locations affected by vehicle emissions. Possibleexceedances of objectives were identified at some locations, though these were inplaces where members of the public were unlikely to spend long periods of time. It wastherefore decided not to declare any air quality management areas. Further monitoringof nitrogen dioxide commenced in order to confirm that no exceedances were occurring.The second round of Review and Assessment was undertaken between 2003 and2005. It reconsidered the seven health based air quality objectives and concluded thatthere was a possible risk of exceedance of the NO 2 objective at several areas, basedon modelling results. The USA concluded that a Detailed Assessment was required fornitrogen dioxide due to road traffic emissions from the M25 (West of the M11), HighStreet (Epping), Hainault Road (Chigwell), Church Hill (Loughton) and A121 Link Road(Waltham Abbey). The outcome of the Detailed Assessment concluded that the NO2annual mean objective would be met at all receptors in all five assessment areas andthat it was not necessary to declare any AQMAs at the time. It also recommended thatmonitoring continued at these locations to confirm that concentrations remained belowthe objective levels. No other locations were considered at risk of exceeding the airquality objectives.The most recent USA (2006) reconsidered the seven health based air quality objectivesand concluded that there was a possible risk of exceedance of the NO 2 objective. It wasnoted that the Council should relocate their diffusion tubes closer to the receptorfacades at those sites nearing exceedance. Following the relocation of tubes to a moreappropriate location monitoring results identified an exceedance at Epping High Streetand it was necessary to declare an AQMA at Epping High Street in January 2008.1


Epping Forest District CouncilLAQM Progress Report 20082. Monitoring dataEpping Forest District Council measures air quality in the district using 52 diffusiontubes; many of these are with co-located tubes. Many of the monitoring sites are newfor 2007, as tubes were relocated to give results more representative of relevantexposure (see figure 2.1). Historic data are reported for those sites that were notrelocated in 2007, data for sites which have been decommissioned have been reportedin earlier air quality reports.The diffusion tubes are supplied and analysed by Gradko using the 50% TEA inacetone method. Gradko International Limited participates in the UK National DiffusionTube Network and the Workplace Analysis Scheme for Proficiency (WASP). Theycurrently hold UKAS accreditation for analysis of diffusion tubes.Technical Guidance (LAQM.TG03) recommends co-location of diffusion tubes with anautomatic analyser to ensure the accurate and representative reporting of NO 2concentrations, with any positive or negative local bias taken into account. In theabsence of a local co-location study the default Defra adjustment factors have beenapplied to the diffusion tube monitoring results.Table 2.1: Bias adjustment factors 2002-2007Year Factor DEFRA Helpdesk2005 1.1 2006 1.04 2007 0.93 The results of the diffusion tube monitoring is summarised in table 2.2.Table 2.2 Nitrogen dioxide diffusion tube results, bias adjustment applied (µgm -3 )Site IDs Location 2005 2006 2007 20101 / 8 Ladbrokes, High Street, Epping 39.7 35.42 / 10 69 & 70 High Street, Epping 37.3 33.221 / 23 Anesty, Ivy Chimneys Road, Epping (near M25) 31.5 28.05 / 24 13 The Elms, Woodbine Close, Waltham Abbey 40.3 36.6 35.9 31.931 / 32 15 The Elms, Woodbine Close, Waltham Abbey 38.4 34.4 37.6 33.46 / 29 34 Hayden Road, Waltham Abbey 37.1 33.07 / 30 3 Howse Road Waltham Abbey 35.0 31.245 / 46 Burrows Chase, Waltham Abbey 34.3 31.1 31.6 28.212 / 13 Hainault Road 105 Manor Road, Chigwell 50.0 44.9 44.3 39.549 / 50 Sherrell House Fencepiece Road 35.1 31.6 29.9 26.651 / 52 Sherrell House – Manor Road 32.7 29.2 27.2 24.222 / 33 Netherhall Lane /Glen Faber Road 25.2 21.0 19.2 17.13 / 34 Crown Close, Sheering 34.4 31.0 29.5 26.34 / 35 The Street, Sheering 31.8 28.9 27.5 24.541 / 42 High Road Tyler’s Green, North Weald 42.3 38.2 39.7 35.311 / 43 1 Canes Cotts, Canes Lane (A414) Hastingwood 45.2 40.1 30.9 27.59 / 44 Rundells Lodge, London Road, Hastingwood 42.3 37.7 28.0 24.915 / 26 5a Goldings Hill, Loughton 49.3 42.9 42.3 37.716 / 19 158a Harwater Drive, Loughton 30.7 27.317 / 18 Zizzi, Church Hill, Loughton 51.5 46.3 36.0 32.120 Brooklyn Court Loughton 31.3 27.925 Loughton High Road 2 43.5 40.5 34.7 30.927 / 14 Timpsons in alley, Loughton 35.1 31.228 76 & 78 Church Hill Loughton 42.1 37.536 / 37 58 Station Road Loughton 27.5 24.547 / 48 Loughton – Maple Gate 33.4 29.8 30.2 26.9Bold: exceeds objectiveDiffusion tube monitoring results show that three monitoring sites exceeded the NO 2annual mean objective in 2007 (see Table 2.1, figures in bold). None of the sites are2


Epping Forest District CouncilLAQM Progress Report 2008predicted to exceed the objective in 2010, although monitoring will continue in order toconfirm that this is the case.A review of 2007 monitoring data at 2 sites was recommended in the DetailedAssessment. These sites were Hayden Road (near Meridian Way) and Woodbine Close(near the M25), both in Waltham Abbey. The Detailed Assessment found a marginalexceedance of monitored data at these two sites, based on short term annualised 2007data. This report presents 2007 annual mean data for the two sites based on acomplete year of monitoring. Concentrations at the two locations were below thenitrogen dioxide objective level in 2007; therefore there is no requirement for thedeclaration of an AQMA at either location.DiscussionThe locations highlighted by the report as potential exceedence areas are allkerbside/roadside sites where it was not possible to reach an agreement with the ownerof the nearest sensitive receptor to undertake façade monitoring. It is generallyconsidered that the actual façade concentrations of NO 2 will be below objective levels.Further ActionFurther modelling work is proposed in order to determine the overall need for and extentof additional AQMAs for the potential exceedence areas highlighted by this progressreport. Indeed, a Defra grant has been applied for in partnership with the District andBorough councils for thing the ‘North London Cluster Group’ to undertake overlappingdistrict and borough wide detailed dispersion modelling, with a view to producing highresolutioncontour mapping.The high-resolution contour maps will be used for pro-active management of air quality,with specific regard to the development process, thereby controlling and minimising newexposure through targeted and managed development and land use.In addition to the above, detailed site specific scenarios will be run, such as thedelineation of any potential future AQMAs.3

Epping Forest District CouncilLAQM Progress Report 20083. Emission sourcesWhen the Updating and Screening Assessment was carried out in 2006, there were 2Part A industrial sources and 45 Part B industrial sources (of which, 21 were petrolstations) in the district of Epping Forest. These are listed in table 3.1. Since the 2007Progress Report was carried out 5 processes ceased to operate and 2 new processescommenced operating. In addition 15 dry cleaning processes have been identified andadded. These are shown in table 3.1. Additional information about changes to existingprocesses are listed in the Notes column of table 3.1.New DevelopmentsThere are currently no planned new developments that are likely to have a detrimentalimpact on air quality.Table 3.1 Industrial Emission Sources in Epping ForestInstallation Activity PG Note NotesHoppings SoftwoodManufacture of timber based 6/2Products Plc.products.Mobile plantC J Pryor (Plant) LimitedCrushing and screening brickstiles and concrete.Rye Street Coachworks Respraying road vehicles. 6/34Grove Coachworks Respraying road vehicles. 6/34Brian L Shilton & Co.

Epping Forest District CouncilLAQM Progress Report 20084. Planning and PoliciesThere are currently no planning applications for new developments for which an airquality assessment is required.Policy RP5a within the Epping Forest District Council Combined Local Plan (amended2008) states that:The Council will not grant planning permission for:(i)development where it could cause excessive noise, vibration, or air, groundwater or light pollution for neighbouring land uses, protected wildlifespecies and habitats; or(ii) sensitive development such as housing (or other forms of residentialoccupation, including mobile homes and caravans), hospitals or schoolswhich could be subject to either excessive noise from adjoining land usesor traffic (road, rail and air), or other forms of adverse environmentalconditions such as air pollution; except where it is possible to mitigate theadverse effects by the imposition of appropriate conditions.5. Local Transport PlanEpping Forest District is covered by the Essex County Council Local Transport Plan.There are a number of general measures in the Essex LTP, which are aimed atreducing the impact of road transport on air quality.The District Council are working in partnership with the Development, Highways andTransportation department to ensure that new traffic management schemes considerthe potential impact on air quality, in particular the impact on the AQMA at Epping HighStreet.6. Summary and ConclusionsThe Progress Report shows that Epping Forest District has recently declared oneAQMA at Epping High Street, following a relocation of diffusion tubes closer to façadereceptors wherever possible.The District Council is working in partnership with key stakeholders to ensure that theair quality in Epping Forest remains below objective limits outside of the one declaredAQMA and continues to improve.The District Council carried out a Detailed Assessment as a result of the findings of theprevious Progress Report. It concluded that concentrations at the two monitoredlocations were below the nitrogen dioxide objective level in 2007 and that thereforethere is no need to declare an AQMA at either location. The next air quality report to beprepared and submitted to Defra will be the 2009 Updating and Screening AssessmentReport.8
